Exploring the association between non-regular employment and adverse birth outcomes: an analysis of national data in Japan.

Background: As few studies have explored the association between non-regular or precarious employment in parents and adverse birth outcomes, this study aimed to investigate this association using national data in Japan. Methods: This study utilized the census data from 2020 and birth data from the vital statistics in 2021 and 2022 in the analysis. Adverse birth outcomes, including preterm birth, term low birth weight (TLBW), and small-for-gestational-age, were examined. Data linkage was conducted between birth data and census data to link parental employment statuses and educational attainments with birth data. Rates of adverse birth outcomes were calculated for each parental employment status. Additionally, regression analysis was used to determine adjusted risk ratios (RRs) of parental employment statuses for each birth outcome. Results: After data linkage, 334,110 birth records were included in the statistical analysis. Rates for non-regular workers were consistently higher than those for regular workers across all adverse birth outcomes for maternal employment status. Results of regression analyses indicated that the risks of preterm birth for non-regular workers were statistically significantly higher than those for regular workers, both in mothers and fathers with a RR (95% confidence intervals [CIs]) of 1.053 (1.004-1.104) and 1.142 (1.032-1.264), respectively. Furthermore, the risk of TLBW birth for non-regular workers was statistically significantly higher than that for regular workers in fathers (RR [95% CI]: 1.092 [1.043-1.143]). Conclusions: Our findings demonstrate that non-regular workers have a higher risk of some adverse birth outcomes compared to regular workers.

Estimated Number of Injection-Involved Overdose Deaths in US States From 2000 to 2020: Secondary Analysis of Surveillance Data.

BACKGROUND: In the United States, both drug overdose mortality and injection-involved drug overdose mortality have increased nationally over the past 25 years. Despite documented geographic differences in overdose mortality and substances implicated in overdose mortality trends, injection-involved overdose mortality has not been summarized at a subnational level. OBJECTIVE: We aimed to estimate the annual number of injection-involved overdose deaths in each US state from 2000 to 2020. METHODS: We conducted a stratified analysis that used data from drug treatment admissions (Treatment Episodes Data Set-Admissions; TEDS-A) and the National Vital Statistics System (NVSS) to estimate state-specific percentages of reported drug overdose deaths that were injection-involved from 2000 to 2020. TEDS-A collects data on the route of administration and the type of substance used upon treatment admission. We used these data to calculate the percentage of reported injections for each drug type by demographic group (race or ethnicity, sex, and age group), year, and state. Additionally, using NVSS mortality data, the annual number of overdose deaths involving selected drug types was identified by the following specific multiple-cause-of-death codes: heroin or synthetic opioids other than methadone (T40.1, T40.4), natural or semisynthetic opioids and methadone (T40.2, T40.3), cocaine (T40.5), psychostimulants with abuse potential (T43.6), sedatives (T42.3, T42.4), and others (T36-T59.0). We used the probabilities of injection with the annual number of overdose deaths, by year, primary substance, and demographic groups to estimate the number of overdose deaths that were injection-involved. RESULTS: In 2020, there were 91,071 overdose deaths among adults recorded in the United States, and 93.1% (84,753/91,071) occurred in the 46 jurisdictions that reported data to TEDS-A. Slightly less than half (38,253/84,753, 45.1%; 95% CI 41.1%-49.8%) of those overdose deaths were estimated to be injection-involved, translating to 38,253 (95% CI 34,839-42,181) injection-involved overdose deaths in 2020. There was large variation among states in the estimated injection-involved overdose death rate (median 14.72, range 5.45-31.77 per 100,000 people). The national injection-involved overdose death rate increased by 323% (95% CI 255%-391%) from 2010 (3.78, 95% CI 3.33-4.31) to 2020 (15.97, 95% CI 14.55-17.61). States in which the estimated injection-involved overdose death rate increased faster than the national average were disproportionately concentrated in the Northeast region. CONCLUSIONS: Although overdose mortality and injection-involved overdose mortality have increased dramatically across the country, these trends have been more pronounced in some regions. A better understanding of state-level trends in injection-involved mortality can inform the prioritization of public health strategies that aim to reduce overdose mortality and prevent downstream consequences of injection drug use.

The effect of educational attainment on birthrate in Japan: an analysis using the census and the vital statistics from 2000 to 2020.

BACKGROUND: In Japan, difference in birth rates depending on educational attainment has not been investigated. This study aimed to reveal birth rates in Japan depending on the highest level of educational attainment and their trends over the years using nationwide government statistics data. METHODS: Individual-level data from Vital Statistics and the Census from 2000, 2010, and 2020 were used for birth and population data, respectively. Data linkage was conducted for males and females in the Census and fathers and mothers in the Vital Statistics using information about gender, household, nationality, marital status, birth year, birth month, prefecture, and municipality for individuals. The birth rate was calculated by gender, a five-year age group, the highest level of educational attainment achieved, and year. In addition, the slope index of inequality (SII) and relative index of inequality (RII) were calculated to evaluate the degree of inequality in birth rates, depending on the educational attainment. RESULTS: Birth rates were higher in persons with lower educational attainment compared to those with a higher educational attainment among males and females in their twenties, while they tended to be higher in persons with higher educational attainment among those in their thirties and forties. Additionally, an increase in the birth rate from 2000 to 2020 was the largest in university graduates among males aged 25-49 years and women aged 30-49 years, and a decrease in the birth rate was the smallest in university graduates among males and females aged 20-24 years. As a result, SII and RII increased from 2000 to 2020 among males and females in their thirties and forties. CONCLUSIONS: In conclusion, persons with higher educational attainment tended to have a relatively favorable trend in the birth rate compared with persons with lower educational attainment in recent decades. It suggested that enhanced administrative support for individuals with lower educational attainment or lower socioeconomic status may be required to ameliorate the declining birth rate in Japan.

Metastatic Sites in Rare Genitourinary Malignancies and Primary Cancer Sites in Genitourinary Organ Metastases: A Secondary Analysis Using the Japanese Pathological Autopsy Registry Database.

Background: The epidemiology of metastases from rare genitourinary cancer and metastases to genitourinary organs from other primary neoplasms remains poorly understood. Objective: To investigate the epidemiology of rare genitourinary metastases from rare genitourinary organ-type cancer and to genitourinary organs using data from a large national autopsy registry in Japan. Design setting and participants: A secondary analysis of the data reported in the Annual of the Pathological Autopsy Cases in Japan and the Japanese Mortality Database from 1993 to 2020 was performed. Outcome measurements and statistical analysis: Via a retrospective epidemiologic analysis, we evaluated the frequency (probability of occurrence [number per person]) and proportion (percentage) of metastases from upper urinary tract, adrenal, testicular, urethral, and penile cancers. Moreover, the sites of primary tumors metastasizing to genitourinary organs were examined. Results and limitations: In Japan, the mortality rate of upper urinary tract cancer is increasing rapidly. In the integrated database with 365 099 autopsies and 835 959 metastatic organs, the major metastatic sites (range of frequency ratios) of rare genitourinary organ-type cancers were the lungs (0.38-0.47), liver (0.21-0.56), bone (0.16-0.33), adrenal gland (0.10-0.20), peritoneum (0.0-0.16), and kidneys (0.07-0.22). The major primary sites (range of proportions) of genitourinary organ metastases were the respiratory tract (5.6-34.0%), stomach (4.7-27.0%), hematologic site (0.9-24.9%), lymphoid (2.4-22.2%), bladder (0.8-20.0%), prostate (0.7-14.1%), rectal (2.0-11.7%), and pancreas (2.6-11.0%). The cancers with a high likelihood of genitourinary metastasis were respiratory and stomach cancers. However, the study lacked individual-level information, and there might be a concomitant selection bias in this autopsy study. Conclusions: This large-scale autopsy database analysis identified the epidemiology of metastasis from rare genitourinary organ-type cancer and the origins of metastasis to genitourinary organs. Patient summary: This study provides valuable metastatic epidemiologic data and clinical information that are fundamental to the mechanisms of genitourinary metastasis.

Trends and disparities in deaths among young persons in the US during the COVID-19 pandemic.

PURPOSE: To examine changes in death rates by demographic group and by the leading causes of death in U.S. persons 1 to 24 years of age during the COVID-19 pandemic. METHODS: A retrospective cross-sectional study using mortality data from the National Vital Statistics System from April 2017 to March 2023. Pre-pandemic death rates were compared with death rates during the pandemic overall, by race/ethnicity, age, sex, and cause group. RESULTS: Age-adjusted death rates in young persons 1-24 years of age increased by 14.3% during the pandemic. Injury-related causes accounted for 78.2% of the increase, driven mainly by increases in homicides and unintentional injuries related to drug overdose, firearms, and motor-vehicle traffic crashes. Non-Hispanic Black and Hispanic teens and young adults experienced the largest increases in deaths overall and across the leading causes of death. CONCLUSIONS: During the COVID-19 pandemic, injury-related causes accounted for the majority of the increases in deaths in children and young adults, driven mainly by firearms, drug overdoses, and motor vehicle traffic crashes. Findings highlight the importance of understanding the drivers of these marked increases in injury-related mortality and the need for injury prevention efforts among children even in the context of an infectious disease pandemic.

Similar geographic distribution of mortality from multiple sclerosis, Hodgkin lymphoma, and inflammatory bowel disease in the United States.

BACKGROUND: Previous epidemiologic studies have suggested a linkage between the occurrence of multiple sclerosis (MS), Hodgkin lymphoma (HL), Crohn's disease (CD), and ulcerative colitis (UC). It was hypothesized that the 4 diagnoses would be characterized by similar geographic distributions within the United States. AIMS: To compare the US geographic distributions of these 4 diagnoses in a cross-sectional study. METHODS: Using the US vital statistics, state-specific death rates and age-specific proportional mortality ratios (PMR) were calculated for each diagnosis. Similarities in the geographic distributions of the 4 diagnoses were tested by linear and Poisson regression analyses. The PMR values from different states were correlated among pairs of consecutive age-groups. RESULTS: The 6 linear correlation coefficients (r) among the geographic distributions of the 4 diseases were as follows: HL vs. MS (r = 0.28), HL vs. CD (r = 0.74), HL vs. UC (r = 0.64); MS vs. CD (r = 0.18), MS vs. UC (r = 0.66); CD vs. UC (r = 0.58). Using Poisson regression, the geographic distributions of MS, HL, CD, and UC were all found to be significantly correlated with each other. In MS, significant correlations between the PMR values of each two consecutive age-groups started with the age-group 25-44 years. In HL, such significant correlations started at age 10-14, in CD at age 20-24, and in UC at age 20-24 years. CONCLUSIONS: Within the United States, mortality from MS, HL, CD, and UC are characterized by similar geographic distributions. The environmental influences responsible for these resembling geographic distributions start exerting their influence during early lifetime.

Análise dos feminicídios no estado de Pernambuco: violência de gênero e invisibilidade / Analysis of femicides in the state of Pernambuco: gender-based violence and invisibility / Análisis de los feminicidios en el estado de Pernambuco: violencia de género e invisibilidad

O feminicídio é um fenômeno decorrente da herança patriarcal machista e de estruturas sociais historicamente permeadas por relações desiguais de gênero. O objetivo desta dissertação, que é um estudo ecológico, foi analisar os aspectos epidemiológicos dos feminicídios registrados em Pernambuco, entre 2016 e 2019. Como proxy dos eventos de feminicídio, foi admitido como referência o registro de homicídios e de mortes por causas indeterminadas de mulheres no Sistema de Informações sobre Mortalidade. Foram estabelecidas etapas de buscas com o linkage probabilístico em bases de dados da saúde e, de forma complementar, de revisões manuais em plataforma do Tribunal de Justiça de Pernambuco (TJPE) e mídias noticiosas online. Realizou-se a descrição dos dados mediante a distribuição de frequências, medidas de tendência central e dispersão. Para analisar o padrão espacial das taxas de feminicídio, foram utilizados o método bayesiano empírico local e o índice de autocorrelação de Moran. Aplicou-se a regressão logística hierarquizada para verificar a associação entre o feminicídio e a violência interpessoal e estimar a razão de chances (Odds Ratio) com intervalos de confiança de 95% (IC95%). Assim, foram localizados 490 feminicídios, o que correspondeu a uma taxa de 2,5 por 100.000 mulheres. A maior proporção de feminicídios foi identificada pela busca manual em mídias noticiosas online e na base processual do TJPE (n = 247; 50,41%). As características principais das vítimas são: idade entre 20 e 39 anos (n = 286; 58,37%); raça/cor negra (n = 400; 81,63%); sem companheiro(a) (n = 407; 83,06%); e escolaridade superior a oito anos de estudo (n = 303; 61,84%). A autocorrelação espacial do evento foi confirmada pelo índice global de Moran das taxas suavizadas (I = 0,3; p = 0,001); a autocorrelação local reforça a interiorização do evento ao apontar área crítica (Q1) formada por municípios localizados na macrorregião do Vale do São Francisco e Araripe. No nível de determinação distal, identificou-se que as seguintes variáveis elevam as chances de ocorrência do feminicídio: residir em município de pequeno porte (OR = 2,10); indisponibilidade de delegacias especializadas no atendimento à mulher (OR = 1,11); e ausência de encaminhamentos para rede assistencial e protetiva na oportunidade de agressão anterior (OR = 1,32). Nos determinantes intermediários, destacou-se que, quanto maior é a intensidade do meio de ação empregado na prática da violência, maior é a chance do desfecho fatal, ressaltando-se o uso de objeto perfurocortante (OR = 3,93) e arma de fogo (OR = 11,14). E, acerca dos determinantes proximais, as vítimas inseridas na faixa etária entre 10 e 19 anos apresentaram menor chance quanto à ocorrência de feminicídio (OR = 0,51). A caracterização da população de estudo pode proporcionar a ampliação dos conhecimentos sobre violência estrutural contra as mulheres, aspectos da notificação e da rede assistencial e protetiva. A análise espacial identificou a interiorização do evento e áreas de transição em Pernambuco, as quais requerem priorização de intervenções. E a modelagem evidenciou que as mulheres estão expostas a múltiplos fatores de risco para a ocorrência de feminicídio, de forma que a discussão, de modo particularizado a todos os níveis de determinação, faz-se ainda mais necessária.

Feminicide results from the sexist patriarchal heritage and social structures historically permeated by unequal gender relations. This ecological study analyzes the epidemiological aspects of feminicides recorded in Pernambuco between 2016 and 2019. Records of homicides and undetermined causes of death of women available in the Mortality Information System were the proxy for feminicide events and accepted as reference. Search steps were established with probabilistic linkage in health databases, as well as manual reviews on the Pernambuco Court of Justice (TJPE) platform and online news media as a complement. Data were described by the distribution of frequencies, measures of central tendency and dispersion. Local empirical Bayesian method and Moran's autocorrelation index were used in the spatial pattern analysis of femicide rates. Hierarchical logistic regression was applied to verify the association between femicide and interpersonal violence and to estimate the Odds Ratio with 95% confidence intervals (95%CI). Search returned a total of 490 feminicides, corresponding to a rate of 2.5 per 100,000 women. The highest proportion of feminicides was identified by manual search in online news media and in the TJPE database (n = 247; 50.41%). Most victims were aged between 20 and 39 years (n = 286; 58.37%), black (n = 400; 81.63%), had no partner (n = 407; 83.06%) and with over eight years of schooling (n = 303; 61.84%). Spatial autocorrelation of the event was confirmed by the Global Moran Index of smoothed rates (I = 0.3; p = 0.001). Local autocorrelation reinforces the interiorization of the phenomenon by pointing to a critical area (Q1) formed by municipalities located in the Vale do São Francisco and Araripe macroregion. At the distal level, the following variables increase the chances of feminicide: living in a small city (OR = 2.10); unavailability of specialized police stations (OR = 1.11); and absence of referrals to the care and protection network in the event of a previous aggression (OR = 1.32). Regarding intermediate determinants, the greater the violence inflicted the greater the chance of a fatal outcome, emphasizing the use of sharp objects (OR = 3.93) and firearms (OR = 11.14). Regarding proximal determinants, victims in the age group 10-19 years old were less likely to be a victim of femicide (OR = 0.51). Characterizing the study population can further knowledge about structural violence against women, and aspects of the notification and the care and protection network. Spatial analysis pointed to the interiorization of the phenomenon and transition areas in Pernambuco, requiring prioritization of interventions. The modeling showed that women are exposed to multiple risk factors for feminicide and further discussions at all levels of determination are necessary.

Este estudio de tipo ecológico tuvo por objetivo analizar los aspectos epidemiológicos de los feminicidios registrados en Pernambuco, en el período entre 2016 y 2019. Como proxy de los eventos de feminicidio, se utilizó como referencia el registro de homicidios y de causas indeterminadas de muertes de mujeres en el Sistema de Informaciones sobre Mortalidad. Se establecieron etapas de búsquedas con vinculación probabilística en las bases de datos de salud y, de forma complementaria, búsquedas manuales en la plataforma del Tribunal de Justicia de Pernambuco (TJPE) y medios en línea. Para describir los datos se utilizaron la distribución de frecuencias, medidas de tendencia central y dispersión. Para analizar el padrón espacial de las tasas de feminicidio se emplearon el método bayesiano empírico local y el índice de autocorrelación de Moran. Se aplicó la regresión logística jerarquizada para constatar la asociación entre el feminicidio y la violencia interpersonal, y estimar la razón de posibilidades (Odds Ratio) con intervalos de confianza del 95% (IC95%). Los resultados apuntaron a 490 feminicidios, lo que correspondió a una tasa de 2,5 por 100.000 mujeres. La mayor proporción de feminicidios se identificó mediante la búsqueda manual en prensa en línea y en la base procesal del TJPE (n = 247; 50,41%). Las principales características de las víctimas fueron edad entre 20 y 39 años (n = 286; 58,37%), raza/color negro (n = 400; 81,63%), sin compañero(a) (n = 407; 83,06%) y nivel de estudios superior a ocho años de estudio (n = 303; 61,84%). La autocorrelación espacial del evento se confirmó mediante el índice de Moran global de las tasas suavizadas (I = 0,3, p = 0,001); la autocorrelación local refuerza la interiorización del evento al señalar área crítica (Q1) formada por municipios situados en la macrorregión del Valle de São Francisco y Araripe. En el nivel de determinación distal se identificó que las siguientes variables aumentan las posibilidades de feminicidio: residir en municipio de pequeño tamaño, (OR = 2,10); indisponibilidad de comisarías especializadas en la atención a la mujer (OR = 1,1); y ausencia de remisiones a la red asistencial y protectora en la ocasión de agresión anterior (OR = 1,32). En los determinantes intermediarios, se destacó que cuanto mayor es la intensidad del medio de acción empleado en la práctica de la violencia, mayor es la posibilidad de desenlace fatal, destacándose el empleo de objeto cortopunzante (OR = 3,93) y arma de fuego (OR = 11,14). En cuanto a los determinantes proximales, las víctimas comprendidas en el tramo de edad comprendido entre los 10 y los 19 años presentaron menos posibilidad de incidencia de feminicidio (OR = 0,51). La caracterización de la población de estudio puede proporcionar la ampliación de los conocimientos sobre violencia estructural contra la mujer, aspectos de la notificación y de la red asistencial protectora. El análisis espacial identificó la interiorización del evento y áreas de transición en Pernambuco, las cuales requieren priorización de las intervenciones. Y el modelaje reveló que las mujeres están expuestas a múltiples factores de riesgo para la incidencia de feminicidio y el debate, de modo particularizado de todos los niveles de determinación, se hace todavía más necesario.

Avaliação da efetividade da intervenção para aprimoramento do Sistema de Informações sobre Mortalidade em Pernambuco, Brasil: um estudo quase-experimental / Evaluation of the effectiveness of the intervention to improve the Brazilian Mortality Information System in Pernambuco, Brazil: a quasi-experimental study / Evaluación de la efectividad de la intervención para mejorar el Sistema de Informaciones sobre la Mortalidad en Pernambuco, Brasil: un estudio cuasiexperimental

Resumo: Avaliou-se a influência da variação da implantação do Sistema de Informações sobre Mortalidade (SIM) nos resultados antes e depois da intervenção para aprimoramento do sistema em Pernambuco, Brasil. Foram explicitados o modelo lógico e a matriz de indicadores e julgamento do SIM. Coletaram-se dados primários nos 184 municípios e dados secundários na base do sistema. Obteve-se o grau de implantação (GI) a partir de indicadores de estrutura e processo, posteriormente relacionado aos de resultado, com base no modelo. A intervenção foi direcionada às falhas identificadas e se desenvolveu mediante etapas estratégicas. Foi calculado o percentual de variação anual do GI e dos resultados antes e depois da intervenção. Classificou-se o SIM como parcialmente implantado nas avaliações pré (70,6%) e pós-intervenção (73,1%), com incrementos em todos os componentes. As Regiões de Saúde seguiram a mesma classificação do âmbito estadual, excetuando-se a XII (80,3%), com escore implantado, após a intervenção. Cobertura do sistema, óbitos com causa básica definida, transferência mensal e envio oportuno de dados situaram-se acima de 90% nas duas avaliações. Houve melhora na completude das Declarações de Óbito infantil e no registro oportuno de eventos notificáveis. O fortalecimento da gestão e operacionalização do SIM por meio de intervenções aplicadas no contexto de produção dos dados pode aprimorar os resultados do sistema.

Abstract: This study evaluated the influence of the variation in the implementation of the Brazilian Mortality Information System (SIM) on the results, before and after the intervention to improve the system in Pernambuco, Brazil. The SIM logical model and matrix of indicators and assessment were described, primary data were collected from the 184 municipalities and secondary data were collected from the system database. The degree of implementation (DI) was obtained from the indicators of structure and process, and then related to result indicators, based on the model. The intervention was directed at the shortcomings identified, and developed using strategic stages. The percentage of annual variation of the DI and the results before and after the intervention were calculated. The SIM was classified as partially implemented in the pre- (70.6%) and post-intervention (73.1%) evaluations, with increments in all components. The Health Regions followed the same classification of the state level, except for XII (80.3%), regarding implemented score after the intervention. The coverage of the system; deaths with a defined underlying cause; monthly transfer; and timely submission of data were above 90% in both evaluations. There was an improvement in the completeness of infant Death Certificates and in the timely recording of notifiable events. Strengthening the management and operationalization of the SIM with interventions applied to data registration can improve the system's results.

Trend of incompleteness of the Robson Classification variables in the Live Birth Information (SINASC) in the state of Paraná, Brazil, 2014-2020 / Tendencia de incompletitud de variables de Clasificación de Robson en el Sistema de Información de Nacidos Vivos en Paraná, 2014-2020 / Tendência de incompletude das variáveis da Classificação de Robson no Sistema de Informação sobre Nascidos Vivos (Sinasc) no estado do Paraná, 2014-2020

ABSTRACT Objective: To assess the incompleteness of the Robson Classification variables in the Live Birth Information System (Sistema de Informação sobre Nascidos Vivos - SINASC), in the state of Paraná, and its trend, 2014-2020. Methods: This was a time-series study that analyzed six variables, according to health macro-regions. Incompleteness was classified (percentage of "ignored" and "blank fields") as follows: excellent (< 1.0%); good (1.0-2.9%); regular (3.0-6.9%); poor (≥ 7.0%). Prais-Winsten regression was used to estimate trends. Results: A total of 1,089,116 births were evaluated. The variable "cesarean section before the onset of labor" was classified as poor in 2014 (39.4%) and 2015 (44.3%) in the state and in all macro-regions, but with a decreasing trend in incompleteness. The variables "gestational age" in the North and Northwest macro-regions, and "parity" and "number of fetuses" in the Northwest macro-region showed an increasing trend. Conclusion: Most of the variables evaluated showed low percentages of incompleteness with a decreasing trend, but there is a need to improve the completion of some variables.

Conclusão: A maioria das variáveis avaliadas mostrou baixos percentuais de incompletude com tendência decrescente, mas é preciso melhorar o preenchimento de algumas variáveis.

Chagas disease deaths detected among garbage codes registered in mortality statistics in Brazil: a study from the buRden of ChAgas dISEase in the contemporary world (RAISE) project.

OBJECTIVES: The objective of this study was to identify Brazil's most critical garbage codes (GCs) reclassified to Chagas disease (ChD) in mortality data and their proportions. We also estimated the potential impact of misclassification on the number of deaths attributed to ChD. STUDY DESIGN: Population-based descriptive study. METHODS: We used the Mortality Information System (SIM; in Portuguese) data before and after routine GC investigation in 2015-2019 to evaluate ChD deaths detected among them. We identified priority GCs, which contributed more than 0.1 % to the percentage of total ChD deaths registered. Spearman's correlation was used to evaluate the association between the reclassification of priority GCs and ChD prevalence. Then, we applied the GC correction factors to estimate the number of deaths attributed to ChD. RESULTS: 22,154 deaths were reported as ChD in the study period. Among them, 1004 deaths originally listed as priority GCs were deaths reclassified to ChD after an investigation in the SIM final database. Unspecific cardiomyopathy (10.2 %), unspecific heart diseases (4.7 %), and heart failure (2.8 %) were GCs with the highest proportions of reclassification to ChD in Brazil. Higher ChD prevalence at the state level was associated with a higher proportion of GC deaths reclassified as ChD. When applying correction factors identified after investigation, we estimated an increase of 26.4 % in registered ChD deaths, mostly in states with higher endemicity. CONCLUSIONS: GCs might conceal deaths due to ChD, particularly in Brazil's states with higher endemicity. The approach suggested in this study may offer an alternative method for estimating ChD-related deaths in endemic countries.

Is there an association between family members' season of birth that could influence birth seasonality? Evidence from Spain and France.

The number of births varies by season. Research on birth seasonality has shown that women's season of birth somehow influences that of their children, but factors underlying the intergenerational transmission of birth seasonality remain unknown. With data from Spain and France, we analysed the possibility of transmission of birth season between generations, testing whether relatives tended to be born in the same season. Results indicated that there was an association-a similarity-between parents' and children's birth seasons, partially explaining the stability of seasonal patterns over time. This association also existed between parents' birth seasons. While parents' association is directly explained by an excess of marriages with spouses born in the same month, the overall association may be explained by two facts: different socio-demographic groups show differentiated birth patterns, and relatives share socio-demographic features. Birth season seems to be related to family characteristics, which should be controlled for when assessing birth-month effects on subsequent social/health outcomes.

Evaluación de la calidad de las estadísticas vitales de niños menores de cinco años. Colombia, 2000-2018

Introducción: Las estadísticas vitales son fundamentales para conocer las condiciones de salud de la población y diseñar intervenciones. De su calidad depende la precisión y validez de las métricas derivadas y la relevancia de las decisiones de política pública. Objetivo: Evaluar la calidad de las estadísticas vitales de niños menores de cinco años en Colombia, entre 2000 y 2018. Métodos: Estudio descriptivo y exploratorio. Se analizó la calidad de los registros de nacidos vivos y defunciones publicados por el DANE, utilizando los criterios recomendados por las Naciones Unidas: exactitud (precisión), cobertura (compleción) y oportunidad. Resultados: Se encontraron registros de nacimientos y defunciones con datos perdidos en categorías que indican gradiente social. El 8,2 % de los registros de defunción tenían como causa básica de muerte códigos poco útiles para la toma de decisiones en salud pública. El 97,8 % de los nacidos vivos fueron registrados durante el mismo año de ocurrencia. El subregistro de la mortalidad infantil se estimó en un 28,9 %, con diferencias entre territorios. Conclusiones: La calidad de las estadísticas vitales en niños menores de cinco años de Colombia mejoró en los 19 años evaluados, en particular en exactitud y oportunidad. Sin embargo, persisten problemas en la asignación de la causa básica de muerte y en el subregistro, con diferencias importantes entre territorios. Mejorar la calidad del sistema de estadísticas vitales debe ser un imperativo ético, en especial para comprender las poblaciones de áreas geográficas históricamente invisibilizadas en el país.

Introduction: Vital statistics are essential to identify the health conditions of a population and design interventions. Vital statistics are essential to understand population health and design public health interventions. The accuracy and validity of the derived metrics and the relevance of public policy decisions depend on its quality. Objetive: To evaluate the quality of the vital statistics of children under five years of age in Colombia, between 2000 and 2018. Methods: A descriptive and exploratory study was carried out and the quality of records of live births and deaths published by DANE was analyzed using the criteria suggested by the United Nations: accuracy (precision), opportunity, and coverage (completeness). Results: Of the death records, 8.2% show codes useless for public health purposes as underlying cause of death. Of the live births, 97.8% were registered during the same year of occurrence. We estimated the underregistration of infant mortality at 28.9%, with differences between territories. Conclusions: The quality of vital statistics of children under five years of age has improved in Colombia in the 19 years analyzed, particularly in accuracy and opportunity. However, problems persist in assigning the underlying cause of death and in underregistration, with significant differences between territories. Improving the quality of the vital statistics system must be an ethical imperative, especially to understand the populations of geographic areas historically invisible in the country.

Birth Notification and Registration: A Survey on Knowledge and Attitude Among Postpartum Women in Northwest Ethiopia.

Background: Birth registration is the official and permanent recording of a child's birth within a civil registry, according to the legal requirements of a country. Although the Sustainable Development Goal targets providing legal identity for all by 2030, birth registration levels remain critically low. Therefore, this study aimed to assess postpartum women's knowledge of and attitudes towards birth registration and its associated factors in Northwest Ethiopia. Methods: An institution-based cross-sectional study was conducted from September 1-30/2022 among 422 participants who were selected using systematic random sampling. A pretested and structured interviewer-administered questionnaire was used to collect the data. Data were entered into EPI Info 7 and analyzed using SPSS version 25. A multivariable logistic regression model was fitted to identify the factors associated with knowledge and attitudes towards birth registration. Variables with a p-value of <0.05 were considered to be significantly associated with the dependent variable. Results: Among the participants, 41.7% had good knowledge of birth registration. Less than one-quarter (22.6%) had a favorable attitude towards birth registration. Having a college and above educational level (AOR = 4.01, 95% CI: 2.3-8.4), being urban resident (AOR = 3.4, 95% CI: 3.1-7.4) and full exposure to media (AOR = 3.02, 95% CI: 1.5-5.7) were associated with knowledge of birth registration. Having primary educational status (AOR = 2.04, 95% CI: 2.96-8.31), being fully exposed to different media (AOR = 2.32, 95% CI: 1.22-11.36) and having four or more antenatal care visits (AOR = 5.10, 95% CI: 1.18-14.35) were associated with favorable attitudes towards birth registration. Conclusion: Postpartum women had poor knowledge of and attitudes towards birth registration. Increasing educated women at all levels, awareness rising through different media and integration of birth registration with antenatal care is crucial for realizing the registration of all births by 2030.

Temporal, seasonal, and spatial patterns in fall-related mortality in Japan: Analysis of national vital statistics from 1975 to 2019.

BACKGROUND: Falls are a significant public health issue in aging societies. This study aimed to examine the temporal, seasonal, and spatial patterns in fall-related mortality in Japan, and to investigate the potential factors associated with fall-related mortality. METHODS: The number of unintentional fall-related deaths from 1979 to 2019 were obtained from Japanese vital statistics and crude and direct age-standardized mortality rates (DSR) were calculated. We also calculated the standardized mortality ratio (SMR) to determine seasonal and prefectural differences. In addition, spatial regression was conducted to examine the potential factors associated with fall-related mortality. RESULTS: The DSR among those over 65 years old showed a decreasing trend from 1979, but remained unchanged from 1990 to 2019. Based on the spatial regression model, the factors significantly associated with SMRs were the proportion of the aged population (Coefficient: 0.049), the number of hospitals (0.118), the number of clinics (1.169), the number of hospital beds (-0.060), and the number of physiotherapists (-0.069) for men; and the proportion of aged single households (-0.060), the number of hospitals (0.132), the number of clinics (1.498), the number of hospital beds (-0.051), and the number of physicians (-0.308) for women. CONCLUSIONS: Fall-related mortality among Japanese elderly people has remained unchanged in recent years. In addition, seasonal and spatial patterns were also observed, and it was found that demographic data and healthcare resources in the prefectures affected fall-related mortality rates. Appropriate prevention measures of fall-related deaths should be considered according to the region-specific characteristics and issues.

Applied risk mapping and spatial analysis of address-level decedent data to inform opioid overdose interventions: The Massachusetts HEALing Communities Study.

BACKGROUND: Death certificate data provide powerful and sobering records of the opioid overdose crisis. In Massachusetts, where address-level decedent data are publicly available upon request, mapping and spatial analysis of fatal overdoses can provide valuable insights to inform prevention interventions. We describe how we used this approach to support a community-level intervention to reduce opioid-involved overdose mortality. METHODS: We developed a method to clean and geocode decedent data that substituted injury locations (the likely location of fatal overdoses) for deaths recorded in hospitals. After geomasking for greater privacy protection, we created maps to visualize the spatial distribution of decedent residence addresses, alone and juxtaposed with drive and walk-time distances to opioid treatment programs (OTPs), and place of death by overdose address. We used spatial statistical analyses to identify locations with significant clusters of overdoses. RESULTS: In the 8 intervention communities, 785 individuals died from opioid-involved overdoses between 2017 and 2020. We found that 19.7% of fatal overdoses were recorded in hospitals, 50.2% occurred at the decedent's residence, and 30.1% at another location. We identified overdose hotspots in study communities. By juxtaposing decedent residence data with drive- and walk-time analyses, we highlighted actionable spatial gaps in access to OTP treatment. CONCLUSION: To better understand local fatal opioid overdose risk environments and inform the development of community-level prevention interventions, we used publicly available address-level decedent data to conduct nuanced spatial analyses. Our approach can be replicated in other jurisdictions to inform overdose prevention responses.

Association of sociodemographic and maternal healthcare factors with birth registration in Angola.

OBJECTIVES: Angola has a high burden of unregistered children and efforts to increase birth-registration coverage have not yielded the desired progress. This study aimed to examine sociodemographic and healthcare-related factors associated with birth registration in Angola. STUDY DESIGN: Secondary data analysis of the Maternal and Child Health (MCH) Handbook randomised controlled trial conducted in Benguela province, Angola and involving 11,006 women. METHODS: For this analysis, we excluded women with missing data on birth registration (n = 1424), multiple gestation (n = 243), and those with infant death (n = 6). The final study population included 9333 women with infants under one year of age. We used multilevel mixed-effects logistic regression analysis to determine sociodemographic and healthcare-related factors associated with the registration of a child's birth. RESULTS: Of the 9333 live births, 25% (95% confidence interval [CI] = 13.4-41.8) were registered, while 21% (95%CI = 11.1-35.7) were registered with certificate. There were higher proportions of registered births among mothers who possessed the MCH Handbook across various demographic and healthcare indicators. Birth registration was most significantly associated with facility-based delivery (odds ratio [OR] = 2.97; 95%CI = 2.45-3.61), possession of MCH Handbook (OR = 2.04; 95%CI = 1.70-2.46), and complete scheduled vaccination visits (OR = 1.69; 95%CI = 1.44-1.97). Higher maternal age and education level, belonging to the highest wealth quintile, beginning antenatal care in the first trimester, attending at least four antenatal care visits, and using postnatal care services were positively associated with registration of birth. CONCLUSION: Maternal healthcare factors showed significant associations with birth registration and integrating birth-registration processes with certain maternal and child health services may further raise awareness and boost registration levels in Angola.

Analysis of the Incidence of Macrosomia in Japan by Parental Nationalities at 5-year Intervals From 1995 to 2020.

OBJECTIVES: We investigated trends in the incidence rate of macrosomia and its association with parental nationalities using Vital Statistics data in Japan. METHODS: We used singleton birth data every 5 years from 1995 to 2020. The incidence rate of macrosomia was calculated according to specific attributes (maternal age, infant's sex, parental nationalities, parity, and household occupation) over time (years). In addition, a log-binomial model was used to investigate the relationship between the incidence of macrosomia and the attributes. This study compared Korea, China, the Philippines, Brazil, and other countries with Japan in terms of parental nationalities. "Other countries" indicates countries except for Japan, Korea, China, the Philippines, and Brazil. RESULTS: The study included 6 180 787 births. The rate of macrosomia in Japan decreased from 1.43% in 1995 to 0.88% in 2020, and the decrease was observed across all parental nationalities. The rates for Japanese parents were the lowest values among parental nationalities during the timespan investigated. Multivariate regression analysis showed that mothers from Korea, China, the Philippines, Brazil, and other countries had a significantly higher risk of macrosomia than those from Japan (risk ratio, 1.91, 2.82, 1.59, 1.74, and 1.64, respectively). Furthermore, fathers from China, the Philippines, Brazil, and other countries had a significantly higher risk of macrosomia than those from Japan (risk ratio, 1.66, 1.38, 1.88, and 3.02, respectively). CONCLUSIONS: The rate of macrosomia decreased from 1995 to 2020 in Japan for parents of all nationalities, and the risk of macrosomia incidence was associated with parental nationality.

Eclampsia, in vitro fertilization and the risk of preterm birth: a retrospective cohort study based on 2,880,759 samples.

Background: Eclampsia and in vitro fertilization (IVF) are independent risk factors for preterm birth. Understanding the combined effects of multiple risk factors for preterm birth is critical to making accurate and personalized risk predictions. This study aimed to explore the interaction between eclampsia and IVF on the risk of preterm birth. Methods: A total of 2,880,759 eligible participants from Birth Data Files in the National Vital Statistics System (NVSS) database 2019 were enrolled in this retrospective cohort study. Some characteristics were collected, such as maternal age, prepregnancy body mass index (BMI), history of preterm birth, paternal age, race, newborn sex. Preterm birth was defined as <37 weeks gestation. Univariate and multivariate logistic regression models were utilized to assess the associations between eclampsia, IVF and preterm birth. The odds ratio (OR) and 95% confidence interval (CI) were calculated in this study. Relative excess risk due to interaction (RERI), attributable proportion (AP) and synergy index (S) were adopted to evaluate the interaction between eclampsia and IVF on the risk of preterm birth. Results: The age of mothers and fathers, the number of multiple births, the proportion of mothers with a history of preterm birth, pregnancy infections, eclampsia and IVF among the preterm birth group were all higher than those among the non-preterm birth group. The incidence of preterm birth in eclampsia and IVF population was approximately 37.31% and 22.96%, separately. After adjusting some covariates, subjects with both eclampsia and IVF had a higher risk of preterm birth (OR =9.197, 95% CI: 6.795-12.448, P<0.001). Furthermore, the results (RERI =3.426, 95% CI: 0.639-6.213, AP=0.374, 95% CI: 0.182-0.565, S =1.723, 95% CI: 1.222-2.428) suggested that the interaction between eclampsia and IVF on preterm birth was statistically significant, indicating a synergistic interaction. Conclusions: Eclampsia and IVF might interact in a synergistic manner to increase the risk of preterm birth. Awareness of the risk profile associated with preterm birth is crucial for pregnant woman with IVF to implement dietary and lifestyle modifications.

Padrões espaciais da mortalidade fetal e carência social no estado de Pernambuco, Brasil / Spatial patterns of fetal mortality and social deprivation in the state of Pernambuco, Brazil / Estándares espaciales de mortalidad fetal y privación social en el estado de Pernambuco, Brasil

A mortalidade fetal é um indicador da assistência obstétrica e de condições de vida capaz de refletir o estado de saúde da mulher e a qualidade e a acessibilidade dos cuidados no pré-natal e na assistência intraparto. Com o objetivo de analisar os padrões espaciais da mortalidade fetal, a evitabilidade dos óbitos e a carência social no estado de Pernambuco, foi realizado um estudo ecológico considerando municípios, regiões de saúde e mesorregiões como unidades de análise. Incluíram-se os óbitos fetais registrados no Sistema de Informação sobre Mortalidade no período de 2010 a 2017. Classificou-se a evitabilidade dos óbitos pela Lista Brasileira de Causas de Mortes Evitáveis por Intervenções do Sistema Único de Saúde. Aplicou-se a estatística descritiva e o teste qui-quadrado para comparação de proporções das causas de morte. Na elaboração do índice de carência social, utilizou-se a técnica de análise fatorial por componentes principais com o teste de esfericidade de Bartlett para identificar a matriz de correlação. Com o índice calculado, os municípios foram agrupados em estratos de carência social pela técnica de k-means. Foram aplicadas a análise bayesiana e a estatística espacial de Moran para identificação de áreas prioritárias de mortalidade fetal e do índice de carência social. Registraram-se 12.337 óbitos fetais, sendo 8.927 (72,3%) por causas evitáveis. As variáveis idade da mãe, número de filhos mortos, tipo de gravidez, tipo de parto e peso ao nascer estiveram relacionadas à evitabilidade do óbito. Na construção do índice de carência social, o teste de esfericidade de Bartlett (χ² de 144,463; p < 0,01) e o coeficiente KMO (0,8) mostraram que as correlações entre os itens eram adequadas para a análise fatorial, assim como as correlações entre os indicadores. O índice de carência social indicou dois fatores que, juntos, explicaram 77,63% da variância total. A taxa de mortalidade fetal evitável apresentou aumento entre estratos de carência social, com taxas de 7,99 por mil nascimentos (baixa carência), 8,06 por mil (média carência), 8,83 por mil (alta carência) e 10,7 por mil (muito alta carência). O índice global de Moran verificou autocorrelação espacial significativa para a taxa de mortalidade fetal bayesiana (I = 0,10; p = 0,05), para a taxa de mortalidade fetal evitável bayesiana (I = 0,13; p = 0,03) e para o índice de carência social (I = 0,53; p = 0,01). Alguns municípios das mesorregiões do São Francisco e do Sertão Pernambucano tiveram simultaneamente elevada mortalidade fetal e mortalidade fetal evitável, além de índice de carência social muito alto. A análise espacial identificou áreas com maior risco para a mortalidade fetal. O índice de carência social relacionou alguns determinantes das mortes fetais em áreas com piores condições de vida. Detectaram-se áreas prioritárias para a intervenção de políticas públicas de redução da mortalidade fetal e seus determinantes.

Fetal mortality is an indicator of obstetric care and living conditions, capable of reflecting the state of women's health and the quality and accessibility of prenatal care and intrapartum care. To analyze the spatial patterns of fetal mortality, preventability of deaths, and social deprivation in the state of Pernambuco, an ecological study was carried out considering municipalities, health regions, and mesoregions as units of analysis. Fetal deaths registered in the Mortality Information System in the period from 2010 to 2017 were included. The deaths are classified as preventable by the Brazilian List of Causes of Preventable Deaths by Interventions of the Unified Health System. Descriptive statistics and the Qui-square test were applied for comparisons of proportions of causes of death. In the elaboration of the social deprivation index, the factorial analysis technique by principal components with the Bartlett's sphericity test was used to identify the correlation matrix. With the calculated index, the municipalities were grouped in social deprivation strata by the k-means technique. Bayesian analysis and Moran's spatial statistics were applied to identify priority areas of fetal mortality and the index of social deprivation. There were 12,337 fetal deaths registered, of which 8,927 (72.3%) were due to preventable causes. The variables of mother's age, number of dead children, type of pregnancy, type of birth, and weight at birth were related to preventability of death. In the construction of the social deprivation index, Bartlett's sphericity test (χ² of 144.463; p < 0.01) and the KMO coefficient (0.8) showed that the correlations between the items were adequate for factor analysis, as well as the correlations between the indicators. The social deprivation index pointed to two factors that, together, explained 77.63% of the total variance. The rate of preventable fetal mortality showed an increase among social deprivation strata, with rates of 7.99 per thousand births (low deprivation), 8.06 per thousand (medium deprivation), 8.83 per thousand (high deprivation), and 10.7 per thousand (very high social deprivation). The global Moran index verified significant spatial autocorrelation for the Bayesian fetal mortality rate (I = 0.10; p = 0.05), for the Bayesian preventable fetal mortality rate (I = 0.13; p = 0.03) e for the o social deprivation index (I = 0.53; p = 0.01). Some municipalities of the mesoregions of São Francisco and of Sertão of Pernambuco have simultaneously high fetal mortality and preventable fetal mortality, in addition to a very high rate of social deprivation. The spatial analysis identified areas with the highest risk for fetal mortality. The index of social deprivation relates to some determinants of fetal deaths in areas with the worst living conditions. We detected priority areas for the intervention of public policies to reduce fetal mortality and its determinants.

La mortalidad fetal es un indicador de la asistencia obstétrica y de las condiciones de vida capaz de reflejar el estado de salud de la mujer y la cualidad y accesibilidad de los cuidados en el prenatal y la asistencia intraparto. Con el objetivo de analizar los estándares espaciales de la mortalidad fetal, la evitabilidad de los fallecimientos y la privación social del estado de Pernambuco (Brasil), se realizó un estudio ecológico con los municipios, las regiones de salud y las mesorregiones como unidades de análisis. Se incluyeron los fallecimientos fetales registrados en el Sistema de Información sobre Mortalidad en el período de 2010 a 2017. Se clasificó la evitabilidad de los fallecimientos desde la Lista Brasileña de Causas de Muertes Evitables por Intervenciones en el Sistema Único de Salud. Se aplicaron la estadística descriptiva y la prueba de chi-cuadrado para comparar las proporciones de las causas de muerte. En la elaboración del índice de privación social, se utilizó la técnica de análisis factorial por componentes principales con la prueba de esfericidad de Bartlett para identificar la matriz de correlación. Con el índice calculado, los municipios se agruparon en estados de privación desde la herramienta de k-means. Se aplicaron el análisis bayesiano y la estadística espacial de Moran para identificar las áreas prioritarias de la mortalidad fetal y el índice de privación social. Se registraron 12.337 fallecimientos fetales, de los cuales 8.927 (72,3%) fueron por causas evitables. Las variables edad de la madre, número de hijos muertos, tipo de embarazo, tipo de parto y peso al nacer estuvieron relacionadas con la evitabilidad del fallecimiento. En la construcción del índice de privación social, la prueba de esfericidad de Bartlett (χ² de 144,463; p < 0,01) y el coeficiente de KMO (0,8) mostraron que las correlaciones entre los ítems estaban adecuadas para el análisis factorial, así como las correlaciones entre los indicadores. El índice de privación social señaló a dos factores que juntos explican el 77,63% de la variancia total. La tasa de mortalidad fetal evitable tuvo un aumento entre los estados de privación social, con tasas de 7,99 por mil nacimientos (baja privación), 8,06 por mil (mediana privación), 8,83 por mil (alta privación) y 10,7 por mil (muy alta privación). El índice global de Moran evaluó la autocorrelación espacial significativa para la tasa de mortalidad fetal bayesiana (I = 0,10; p = 0,05), para la tasa de mortalidad fetal evitable bayesiana (I = 0,13; p = 0,03) y para el índice de privación social (I = 0,53; p = 0,01). Algunos municipios de las mesorregiones de São Francisco y de Sertão Pernambucano tuvieron alta mortalidad fetal, además del índice de privación social muy alto. Un análisis espacial identificó áreas con mayor riesgo de mortalidad fetal. El índice de privación social relacionó algunas de las causas de las muertes fetales en áreas con peores condiciones de vida. Se detectaron las áreas prioritarias a la intervención de las políticas públicas para reducir la mortalidad fetal y sus determinantes.

Discrepancies between preliminary and final COVID-19 mortality data-the case of Serbia.

PURPOSE: Since the start of the COVID-19 pandemic, countries have scrambled to set up data collection and dissemination pipelines for various online datasets. This study aims to evaluate the reliability of the preliminary COVID-19 mortality data from Serbia, which has been included in major COVID-19 databases and utilized for research purposes worldwide. METHODS: Discrepancies between the preliminary mortality data and the final mortality data in Serbia were analyzed. The preliminary data were reported through an emergency-necessitated system, while the final data were generated by the regular vital statistics pipeline. We identified databases that include these data and conducted a literature review of articles that utilized them. RESULTS: The number of deaths due to COVID-19 in Serbia, as reported preliminarily, does not align with the final death toll, which is more than three times higher. Our literature review identified at least 86 studies that were impacted by these problematic data. CONCLUSIONS: We strongly advise researchers to disregard the preliminary COVID-19 mortality data from Serbia due to the significant discrepancies with the final data. We recommend validating any preliminary data using excess mortality if all-cause mortality data are available.
