Fatores associados ao óbito entre diabéticos com covid-19 no município de Vitória da Conquista ­ Bahia / Factors associated with death among diabetics with covid-19 in Vitória da Conquista, Bahia / Factores asociados con la muerte en personas diabéticas con covid-19 en el municipio de Vitória da Conquista, en Bahía

Este trabalho objetiva caracterizar o perfil de mortalidade entre diabéticos com covid-19, em Vitória da Conquista, na Bahia, entre 2020 e 2021. É um estudo descritivo e quantitativo, com dados municipais do Sistema de Informação Epidemiológica da Gripe (SIVEP-Gripe). Foram considerados para o estudo pacientes diabéticos com idade ≥ 20 anos, entre abril de 2020 e setembro de 2021. Foi estimada a Odds Ratio (OR) de óbito com intervalos de confiança de 95%. Foram 1423 casos, a maioria do sexo feminino e idade ≥ 70 anos, com 11,6% de óbito. As maiores chances de óbito foram associadas ao sexo masculino (OR 1,60), idade ≥ 70 anos (OR 7,85), com dessaturação de oxigênio (OR 9,55), doença cardíaca crônica (OR 1,71) e doença renal crônica em estágio avançado (OR 3,15). Os pacientes com ≥ 70 anos apresentaram a dessaturação de oxigênio como principal achado clínico. A doença cardíaca crônica, a doença renal crônica em estágio avançado e a imunossupressão foram associadas a um maior risco de óbito.

This study characterizes the mortality profile among diabetics with COVID-19 in Vitoria da Conquista, Bahia, between 2020 and 2021. A descriptive quantitative study was conducted with data obtained from the municipal Influenza Epidemiological Information System (SIVEP ­ Gripe). Inclusion criteria consisted of diabetic patients aged ≥20 years, hospitalized between April 2020 and September 2021. Odds Ratio (OR) of death was calculated with 95% confidence intervals. A total of 1423 cases were registered, most of them involving female patients aged ≥ 70 years, with 11.6% resulting in death. The highest odds of death were associated with male sex (OR 1.60), age ≥ 70 years (OR 7.85), with oxygen desaturation (OR 9.55), chronic heart disease (OR 1.71) and advanced-stage chronic kidney disease (OR 3.15). Patients aged ≥ 70 years presented oxygen desaturation as the main clinical finding. Chronic heart disease, advanced-stage chronic kidney disease, and immunosuppression were associated with increased risk of death.

Determinantes do nascimento prematuro: proposta de um modelo teórico hierarquizado / Determinants of preterm birth: proposal for a hierarchical theoretical model

Resumo O nascimento prematuro (NP) é uma síndrome resultante de uma complexa relação entre múltiplos fatores que não possuem relações e causalidade totalmente compreendidas. Esse artigo traz uma discussão de um modelo teórico hierarquizado dos determinantes de NP, considerando características maternas como aspectos sociodemográficos, psicossociais, nutricionais, comportamentais e biológicos, tradicionalmente associados ao risco aumentado de NP. As variáveis foram distribuídas em seis dimensões, alocadas em três níveis hierárquicos (distal, intermediário e proximal). Nesse modelo, os determinantes socioeconômicos da mãe, da família, do domicílio e do bairro exercem efeitos indiretos sobre o NP por meio de variáveis no nível intermediário, que por sua vez afetam fatores biológicos de risco no nível proximal, os quais apresentam um efeito direto sobre o NP. O estudo adota um modelo teórico hierarquizado dos fatores envolvidos na cadeia de determinação do NP e suas inter-relações. O entendimento dessas inter-relações é um passo importante na tentativa de interromper a cadeia causal que torna algumas mulheres vulneráveis ao parto prematuro.

Abstract Preterm birth (PB) is a syndrome resulting from a complex relationship between multiple factors which do not have fully understood relationships and causality. This article discusses a hierarchical theoretical model of PB determinants, considering maternal characteristics such as sociodemographic, psychosocial, nutritional, behavioral and biological aspects, traditionally associated with increased risk of PB. The variables were distributed in six dimensions within three hierarchical levels (distal, intermediate and proximal). In this model, the socioeconomic determinants of the mother, family, household and neighborhood play indirect effects on PB through variables at the intermediate level, which in turn affect biological risk factors at the proximal level that have a direct effect on PB. The study presents a hierarchical theoretical model of the factors involved in the PB determination chain and their interrelationships. Understanding these interrelationships is an important step in trying to break the causal chain that makes some women vulnerable to preterm birth.

Performance evaluation of tuberculosis control in Brazilian municipalities.

OBJECTIVE: To evaluate the performance of tuberculosis control in Brazilian municipalities. METHODS: This is an ecological study on Brazilian municipalities that notified at least four new cases of tuberculosis, with a minimum of one new case of pulmonary tuberculosis between 2015 and 2018. The municipalities were stratified according to the population in < 50 thousand, 50-100 thousand, 100-300 thousand, and > 300 thousand inhabitants, and the k-means method was used to group them within each population range according to the performance of six indicators of the disease. RESULTS: A total of 2,845 Brazilian municipalities were included, comprising 98.5% (208,007/211,174) of new tuberculosis cases in the period. For each population range, three groups (A, B, and C) of municipalities were identified according to the performance of the indicators: A, the most satisfactory; B, the intermediates; and C, the least satisfactory. Municipalities in group A with < 100 thousand inhabitants presented results above the targets for laboratory confirmation (≥ 72%), abandonment (≤ 5%), and cure (≥ 90%), and comprised 2% of new cases of the disease. Conversely, municipalities of groups B and C presented at least five indicators with results below the targets - HIV testing (< 100%), contact investigation (< 90%), directly observed therapy (< 90%), abandonment (> 5%), and cure (< 90%) -, and corresponded to 66.7% of new cases of tuberculosis. In group C of municipalities with > 300 thousand inhabitants, which included 19 of the 27 capitals and 43.1% of new cases of tuberculosis, the lowest percentages of contact investigation (mean = 56.4%) and directly observed therapy (mean = 15.4%) were verified, in addition to high abandonment (mean = 13.9%) and low coverage of primary health care (mean = 66.0%). CONCLUSIONS: Most new cases of tuberculosis occurred in municipalities with unsatisfactory performance for disease control. Expanding the coverage of primary health care in these places can reduce abandonment and increase the contact investigation and directly observed therapy.

Evaluating the effect of Bolsa Familia, Brazil's conditional cash transfer programme, on maternal and child health: A study protocol.

BACKGROUND: Conditional Cash Transfer Programs have been developed in Latin America in response to poverty and marked social inequalities on the continent. In Brazil, the Bolsa Familia Program (BFP) was implemented to alleviate poverty and improve living conditions, health, and education for socioeconomically vulnerable populations. However, the effect of this intervention on maternal and child health is not well understood. METHODS: We will evaluate the effect of BFP on maternal and child outcomes: 1. Birth weight; 2. Preterm birth; 3. Maternal mortality; and 4. Child growth. Dynamic retrospective cohort data from the 100 Million Brazilian Cohort (2001 to 2015) will be linked to three different databases: Live Birth Information System (2004 to 2015); Mortality Information System (2011 to 2015); and Food and Nutritional Surveillance System (2008 to 2017). The definition of exposure to the BFP varies according to the outcome studied. Those who never received the benefit until the outcome or until the end of the follow-up will be defined as not exposed. The effects of BFP on maternal and child outcomes will be estimated by a combination of propensity score-based methods and weighted logistic regressions. The analyses will be further stratified to reflect changes in the benefit entitlement before and after 2012. DISCUSSION: Harnessing a large linked administrative cohort allows us to assess the effect of the BFP on maternal and child health, while considering a wide range of explanatory and confounding variables.

RESUMO OBJETIVO Avaliar o desempenho no controle da tuberculose dos municípios brasileiros. MÉTODOS Estudo ecológico com municípios brasileiros que notificaram pelo menos quatro casos novos de tuberculose, com no mínimo um caso novo de tuberculose pulmonar entre 2015 e 2018. Os municípios foram estratificados de acordo com a população em < 50 mil, 50-100 mil, 100-300 mil e > 300 mil habitantes e foi utilizado o método k-médias para agrupá-los dentro de cada faixa populacional segundo desempenho de seis indicadores da doença. RESULTADOS Foram incluídos 2.845 municípios brasileiros abrangendo 98,5% (208.007/211.174) dos casos novos de tuberculose do período. Para cada faixa populacional identificou-se três grupos (A, B e C) de municípios segundo desempenho dos indicadores: A os mais satisfatórios, B os intermediários e C os menos satisfatórios. Municípios do grupo A com < 100 mil habitantes apresentaram resultados acima das metas para confirmação laboratorial (≥ 72%), abandono (≤ 5%) e cura (≥ 90%), e abrangeram 2% dos casos novos da doença. Por outro lado, os municípios dos grupos B e C apresentaram pelo menos cinco indicadores com resultados abaixo das metas - testagem HIV (< 100%), exame de contatos (< 90%), tratamento diretamente observado (< 90%), abandono (> 5%) e cura (< 90%) -, e corresponderam a 66,7% dos casos novos de tuberculose. Já no grupo C dos municípios com > 300 mil habitantes, que incluiu 19 das 27 capitais e 43,1% dos casos novos de tuberculose, encontrou-se os menores percentuais de exames de contatos (média = 56,4%) e tratamento diretamente observado (média = 15,4%), elevado abandono (média = 13,9%) e baixa cobertura da atenção básica (média = 66,0%). CONCLUSÕES Grande parte dos casos novos de tuberculose ocorreu em municípios com desempenho insatisfatório para o controle da doença, onde expandir a cobertura da atenção básica pode reduzir o abandono e elevar o exame de contatos e tratamento diretamente observado.

Methods to evaluate COVID-19 vaccine effectiveness, with an emphasis on quasi-experimental approaches. / Métodos para avaliação da efetividade de vacinas para COVID-19 com ênfase em abordagens quase-experimentais.

The evaluation of vaccine effectiveness is conducted with real-world data. They are essential to monitor the performance of vaccination programmes over time, and in the context of the emergence of new variants. Until now, the effectiveness of COVID-19 vaccines has been assessed based on classic methods, such as cohort and test-negative case-control studies, which may often not allow for adequate control of inherent biases in the assignment of vaccination campaigns. The aim of this review was to discuss the study designs available to evaluate vaccine effectiveness, highlighting quasi-experimental studies, which seek to mimic randomized trials, by introducing an exogenous component to allocate to treatment, in addition to the advantages, limitations, and applicability in the context of Brazilian data. The use of quasi-experimental approaches, such as interrupted time series, difference-in-differences, propensity scores, instrumental variables, and regression discontinuity design, are relevant due to the possibility of providing more accurate estimates of COVID-19 vaccine effectiveness. This is especially important in scenarios such as the Brazilian, which characterized by the use of various vaccines, with the respective numbers and intervals between doses, applied to different age groups, and introduced at different times during the pandemic.

A avalição da efetividade de vacinas é feita com dados do mundo real e é essencial para monitorar o desempenho dos programas de vacinação ao longo do tempo bem como frente a novas variantes. Até o momento, a avaliação da efetividade das vacinas para COVID-19 tem sido baseada em métodos clássicos como estudos de coorte e caso controle teste-negativo, que muitas vezes podem não permitir o adequado controle dos vieses intrínsecos da alocação das campanhas de vacinação. O objetivo dessa revisão foi discutir os desenhos de estudo disponíveis para avaliação de efetividade das vacinas, enfatizando os estudos quase-experimentais, que buscam mimetizar os estudos aleatorizados ao introduzir um componente exógeno para atribuição ao tratamento, bem como suas vantagens, limitações e aplicabilidade no contexto dos dados brasileiros. O emprego de métodos quase-experimentais, incluindo as séries temporais interrompidas, o método de diferença em diferenças, escore de propensão, variáveis instrumentais e regressão descontínua, são relevantes pela possibilidade de gerar estimativas mais acuradas da efetividade de vacinas para COVID-19 em cenários como o brasileiro, que se caracteriza pelo uso de várias vacinas, com respectivos número e intervalos entre doses, aplicadas em diferentes faixas etárias e em diferentes momentos da pandemia.

Evaluation of the Effectiveness of Brazilian Community Restaurants for the Dimension of Low-Income People Access to Food.

This study aimed to evaluate the effectiveness of community restaurants (CRs), managed by the Government of the State of Bahia/Brazil, for the dimension of access to food. The study used secondary data obtained from the public opinion survey Profile of users of community restaurants in Salvador. The nutritional information was accessed through the analysis of CRs' menus. Adequate effectiveness of access to food was considered when the CR served meals to 50% to 70% of the users considered the target audience (individuals served by the two CRs located in the city of Salvador/Bahia/Brazil). The participants (n = 1464; 778 as low-income individuals) were adult CR users from Salvador/Brazil. Most of the respondents were male, 40 to 54 years old, not white, had up to 9 years of formal education, without a partner, and living in the municipality of Salvador. The evaluated CRs are effective in serving 53.1% of the target population in their total service capacity. Meal provision only reached an estimated 0.7% of the socially vulnerable community in the district. The average energy value of the meal served by the CR units was 853.05 kcal/meal, with a mean energy density composition classified as average (1.15 kcal/g). The effectiveness of the evaluated community restaurants showed that these instruments were minimally effective in promoting access to food for the low-income population within their total daily service capacity, and the current quantity of these facilities was insufficient. However, these instruments stand out in the fundamental role of promoting the daily distribution of meals to the Brazilian population with the highest social vulnerability levels.

Combined association of obesity and other cardiometabolic diseases with severe COVID-19 outcomes: a nationwide cross-sectional study of 21 773 Brazilian adult and elderly inpatients.

OBJECTIVES: To investigate the combined association of obesity, diabetes mellitus (DM) and cardiovascular disease (CVD) with severe COVID-19 outcomes in adult and elderly inpatients. DESIGN: Cross-sectional study based on registry data from Brazil's influenza surveillance system. SETTING: Public and private hospitals across Brazil. PARTICIPANTS: Eligible population included 21 942 inpatients aged ≥20 years with positive reverse transcription-PCR test for SARS-CoV-2 until 9 June 2020. MAIN OUTCOME MEASURES: Severe COVID-19 outcomes were non-invasive and invasive mechanical ventilation use, intensive care unit (ICU) admission and death. Multivariate analyses were conducted separately for adults (20-59 years) and elders (≥60 years) to test the combined association of obesity (without and with DM and/or CVD) and degrees of obesity with each outcome. RESULTS: A sample of 8848 adults and 12 925 elders were included. Among adults, obesity with DM and/or CVD showed higher prevalence of invasive (prevalence ratio 3.76, 95% CI 2.82 to 5.01) and non-invasive mechanical ventilation use (2.06, 1.58 to 2.69), ICU admission (1.60, 1.40 to 1.83) and death (1.79, 1.45 to 2.21) compared with the group without obesity, DM and CVD. In elders, obesity alone (without DM and CVD) had the highest prevalence of ICU admission (1.40, 1.07 to 1.82) and death (1.67, 1.00 to 2.80). In both age groups, obesity alone and combined with DM and/or CVD showed higher prevalence in all outcomes than DM and/or CVD. A dose-response association was observed between obesity and death in adults: class I 1.32 (1.05 to 1.66), class II 1.41 (1.06 to 1.87) and class III 1.77 (1.35 to 2.33). CONCLUSIONS: The combined association of obesity, diabetes and/or CVD with severe COVID-19 outcomes may be stronger in adults than in elders. Obesity alone and combined with DM and/or CVD had more impact on the risk of COVID-19 severity than DM and/or CVD in both age groups. The study also supports an independent relationship of obesity with severe outcomes, including a dose-response association between degrees of obesity and death in adults.

Epidemiological characteristics and temporal trends of new leprosy cases in Brazil: 2006 to 2017.

Our study aims to describe trends in new case detection rate (NCDR) of leprosy in Brazil from 2006 to 2017 overall and in subgroups, and to analyze the evolution of clinical and treatment characteristics of patients, with emphasis on cases diagnosed with grade 2 physical disabilities. We conducted a descriptive study to analyze new cases of leprosy registered in the Brazilian Information System for Notificable Diseases (SINAN), from 2006-2017. We calculated the leprosy NCDR per 100,000 inhabitants (overall and for individuals aged < 15 and ≥ 15 years) by sex, age, race/ethnicity, urban/rural areas, and Brazilian regions, and estimated the trends using the Mann-Kendall non-parametric test. We analyzed the distributions of cases according to relevant clinical characteristics over time. In Brazil, there was a sharp decrease in the overall NCDR from 23.4/100,000 in 2006 to 10.3/100,000 in 2017; among children < 15 years, from 6.94 to 3.20/100,000. The decline was consistent in all Brazilian regions and race/ethnicity categories. By 2017, 70.2% of the cases were multibacillary, 30.5% had grade 1 (G1D) or 2 (G2D) physical disabilities at diagnosis and 42.8% were not evaluated at treatment completion/discharge; cases with G2D at diagnosis were mostly detected in urban areas (80%) and 5% of cases died during the treatment (leprosy or other causes). Although the frequency of leprosy NCDR decreased in Brazil from 2006 to 2017 across all evaluated population groups, the large number of cases with multibacillary leprosy, physical disabilities or without adequate evaluation, and among children suggest the need to reinforce timely diagnosis and treatment to control leprosy in Brazil.

Physical disabilities caused by leprosy in 100 million cohort in Brazil.

BACKGROUND: Leprosy continues to be an important cause of physical disability in endemic countries such as Brazil. Knowledge of determinants of these events may lead to better control measures and targeted interventions to mitigate its impact on affected individuals. This study investigated such factors among the most vulnerable portion of the Brazilian population. METHODS: A large cohort was built from secondary data originated from a national registry of applicants to social benefit programs, covering the period 2001-2015, including over 114 million individuals. Data were linked to the leprosy notification system utilizing data from 2007 until 2014. Descriptive and bivariate analyses lead to a multivariate analysis using a multinomial logistic regression model with cluster-robust standard errors. Associations were reported as Odds Ratios with their respective 95% confidence intervals. RESULTS: Among the original cohort members 21,565 new leprosy cases were identified between 2007 and 2014. Most of the cases (63.1%) had grade zero disability. Grades 1 and 2 represented 21 and 6%, respectively. Factors associated with increasing odds of grades 1 and 2 disability were age over 15 years old (ORs 2.39 and 1.95, respectively), less schooling (with a clear dose response effect) and being a multibacillary patient (ORs 3.5 and 8.22). Protective factors for both grades were being female (ORs 0.81 and 0.61) and living in a high incidence municipality (ORs 0.85 and 0.67). CONCLUSIONS: The findings suggest that the developing of physical disabilities remains a public health problem which increases the burden of leprosy, mainly for those with severe clinical features and worse socioeconomic conditions. Early diagnosis is paramount to decrease the incidence of leprosy-related disability and our study points to the need for strengthening control actions in non-endemic areas in Brazil, where cases may be missed when presented at early stages in disease. Both actions are needed, to benefit patients and to achieve the WHO goal in reducing physical disabilities among new cases of leprosy.

Associated factors with spatial variation of adolescent pregnancy in Brazil, 2014: an ecological study of spatial clusters. / Fatores associados à variação espacial da gravidez na adolescência no Brasil, 2014: estudo ecológico de agregados espaciais.

OBJECTIVE: To identify socioeconomic and health care determinants of spatial variation in adolescent pregnancy in Brazil in 2014. METHODS: This was a spatial ecological study having municipalities as units of analysis. Spatial linear regression was used to verify association between the fertility rate in 15-19 year-old women and socioeconomic and health variables. RESULTS: The adolescent fertility rate was negatively associated with higher Family Health Strategy coverage (ß = -0.011 - 95%CI -0.017;-0.005), an adequate number of prenatal consultations (ß = -0.122 - 95%CI -0.132;-0.224) and low average family income per capita (ß = -0.104 - 95%CI -0.105;-0.103). Association was positive in relation to the Gini index (ß = 7.031 - 95%CI 4.793;9.269), low income (ß = 0.127 - 95%CI 0.108;0.145), higher household density (ß = 6.292 - 95%CI 5.062;7.522) and less schooling (ß = 0.260 - 95%CI 0.224;0.295). CONCLUSION: Reduced access to primary care and lower income are associated with higher adolescent fertility rates. Poorer socioeconomic and health care indicators are associated with higher adolescent fertility rates.

The relationship between nutritional deficiencies and mental health

ABSTRACT The objective of this mini review was to discuss the relationship between nutritional deficiencies and mental health, and to present a structure that helps to visualize these associations based on a literature review and the scenarios of the COVID-19 pandemic. The study was conducted to demonstrate the effect of the nutritional deficiencies on the occurrence and/or worsening of mental health problems, mainly related to the most drastic measures of social distance during the COVID-19 pandemic. Studies have already shown that a nutritionally unbalanced diet may be associated with greater chances of mental health problems. Insufficient levels of micronutrients can, by regulating the stress response, immune and oxidative systems, negatively affect brain functions and, consequently, cognitive functions and mental health of individuals. The current pandemic of COVID-19 reveals an increase in food and nutritional insecurity, and a worsening of this situation among already vulnerable populations. Micronutrient deficiencies may be exacerbated in a context of increased food insecurity and the COVID-19 pandemic, which may contribute to increased mental health problems.

RESUMEN El objetivo de esta revisión fue discutir la relación entre las deficiencias nutricionales y la salud mental, y presentar una estructura que ayude a visualizar estas asociaciones con base en la revisión de la literatura y en los escenarios de la pandemia de COVID-19. El estudio se realizó para demostrar el efecto de las deficiencias nutricionales sobre la ocurrencia y/o agravamiento de problemas de salud mental, principalmente relacionados con las medidas más drásticas de distanciamiento social durante la pandemia COVID-19. Los estudios ya han demostrado que una dieta nutricionalmente desequilibrada puede estar asociada con mayores posibilidades de problemas de salud mental. Los niveles insuficientes de micronutrientes pueden, al regular la respuesta al estrés, los sistemas inmunológico y oxidativo, afectar negativamente las funciones cerebrales y, en consecuencia, las funciones cognitivas y la salud mental de las personas. La actual pandemia de COVID-19 revela un aumento de la inseguridad alimentaria y nutricional, y un agravamiento de esta situación entre poblaciones ya vulnerables. Las deficiencias de micronutrientes pueden agravarse en un contexto de mayor inseguridad alimentaria y la pandemia de COVID-19, lo que puede contribuir a un aumento de los problemas de salud mental.

Objetivo: Identificar determinantes socioeconômicos e de atenção à saúde na variação espacial da gravidez na adolescência, Brasil, 2014. Métodos: Estudo ecológico espacial com municípios como unidades de análise. Utilizou-se regressão linear espacial para verificar associações entre taxa de fecundidade em adolescentes de 15 a 19 anos e variáveis socioeconômicas e de saúde. Resultados: A fecundidade na adolescência associou-se negativamente a maior cobertura da Estratégia Saúde da Família (ß = -0,011 ­ IC95% -0,017;-0,005), número adequado de consultas de pré-natal (ß = -0,122 ­ IC95% -0,224;-0,132) e menor renda familiar média per capita (ß = -0,104 ­ IC95% -0,105;-0,103); e positivamente, ao índice de Gini (ß = 7,031 ­ IC95% 4,793;9,269), baixa renda (ß = 0,127 ­ IC95% 0,108;0,145), maior densidade domiciliar (ß = 6,292 ­ IC95% 5,062;7,522) e baixa escolaridade (ß = 0,260 ­ IC95% 0,224;0,295). Conclusão: Menores acesso a atenção básica e renda associam-se a maior taxa de fecundidade na adolescência. Piores indicadores socioeconômicos e de atenção à saúde associam-se a maior taxa de fecundidade na adolescência.

Objetivo: Identificar determinantes socioeconómicos y de atención a la salud en la variación espacial del embarazo adolescente en Brasil en 2014. Métodos Estudio espacial ecológico con municipios como unidades de análisis. La regresión lineal espacial se utilizó para verificar la asociación entre la tasa de fecundidad adolescente (15-19 años) y variables socioeconómicas y de salud. Resultados: La tasa de fecundidad adolescente se asoció negativamente con mayor cobertura de la Estrategia de Salud Familiar (ß = -0,011 ­ IC95% -0,017;-0,005), número adecuado de consultas prenatales (ß = -0.122 ­ IC95% -0,132;-0,224) e bajo ingreso familiar promedio per cápita (ß = -0,104 ­ IC95% -0,105;-0,103). Esta asociación fue positiva con el índice de Gini (ß = 7,031 ­ IC95% 4,793; 9,269), bajos ingresos (ß = 0,127 ­ IC95% 0,108; 0,145), mayor densidad familiar (ß = 6,292 ­ IC95% 5,062; 7,522) y baja escolaridad (ß = 0,260 ­ IC95% 0,224; 0,295). Conclusión: El menor acceso a la atención primaria y menores ingresos están asociados con una mayor fecundidad en la adolescencia. Los peores indicadores socioeconómicos y de atención a la salud se asocian con una mayor tasa de fecundidad en la adolescencia.

Objective: To identify socioeconomic and health care determinants of spatial variation in adolescent pregnancy in Brazil in 2014. Methods: This was a spatial ecological study having municipalities as units of analysis. Spatial linear regression was used to verify association between the fertility rate in 15-19 year-old women and socioeconomic and health variables. Results: The adolescent fertility rate was negatively associated with higher Family Health Strategy coverage (ß = -0.011 - 95%CI -0.017;-0.005), an adequate number of prenatal consultations (ß = -0.122 - 95%CI -0.132;-0.224) and low average family income per capita (ß = -0.104 - 95%CI -0.105;-0.103). Association was positive in relation to the Gini index (ß = 7.031 - 95%CI 4.793;9.269), low income (ß = 0.127 - 95%CI 0.108;0.145), higher household density (ß = 6.292 - 95%CI 5.062;7.522) and less schooling (ß = 0.260 - 95%CI 0.224;0.295). Conclusion: Reduced access to primary care and lower income are associated with higher adolescent fertility rates. Poorer socioeconomic and health care indicators are associated with higher adolescent fertility rates.

Epidemiological characteristics and temporal trends of new leprosy cases in Brazil: 2006 to 2017 / Características epidemiológicas e tendências temporais de casos novos de hanseníase no Brasil: 2006 a 2017 / Características epidemiológicas y tendencias temporales de nuevos casos de lepra en Brasil: de 2006 a 2017

Abstract: Our study aims to describe trends in new case detection rate (NCDR) of leprosy in Brazil from 2006 to 2017 overall and in subgroups, and to analyze the evolution of clinical and treatment characteristics of patients, with emphasis on cases diagnosed with grade 2 physical disabilities. We conducted a descriptive study to analyze new cases of leprosy registered in the Brazilian Information System for Notificable Diseases (SINAN), from 2006-2017. We calculated the leprosy NCDR per 100,000 inhabitants (overall and for individuals aged < 15 and ≥ 15 years) by sex, age, race/ethnicity, urban/rural areas, and Brazilian regions, and estimated the trends using the Mann-Kendall non-parametric test. We analyzed the distributions of cases according to relevant clinical characteristics over time. In Brazil, there was a sharp decrease in the overall NCDR from 23.4/100,000 in 2006 to 10.3/100,000 in 2017; among children < 15 years, from 6.94 to 3.20/100,000. The decline was consistent in all Brazilian regions and race/ethnicity categories. By 2017, 70.2% of the cases were multibacillary, 30.5% had grade 1 (G1D) or 2 (G2D) physical disabilities at diagnosis and 42.8% were not evaluated at treatment completion/discharge; cases with G2D at diagnosis were mostly detected in urban areas (80%) and 5% of cases died during the treatment (leprosy or other causes). Although the frequency of leprosy NCDR decreased in Brazil from 2006 to 2017 across all evaluated population groups, the large number of cases with multibacillary leprosy, physical disabilities or without adequate evaluation, and among children suggest the need to reinforce timely diagnosis and treatment to control leprosy in Brazil.

Resumo: O estudo teve com objetivos descrever as tendências na taxa de detecção de casos novos (TDCN) de hanseníase no Brasil em 2006-2017, global e por subgrupos, e analisar a evolução das características clínicas e terapêuticas dos pacientes, com ênfase nos casos diagnosticados com incapacidade física grau 2. Realizamos um estudo descritivo par analisar casos novos de hanseníase registrados no Sistema de Informação de Agravos de Notificação (SINAN), 2006-2017. Calculamos a TDCN de hanseníase por 100.000 habitantes (global e para indivíduos < 15 e ≥ 15 anos de idade) por sexo, idade, raça/etnicidade, área urbana/rural e macrorregião do Brasil e estimamos as tendências com o teste não paramétrico de Mann-Kendall. Analisamos as distribuições de casos de acordo com características clínicas relevantes ao longo do tempo. No Brasil, houve uma queda marcante na TDCN global, de 23,4/100.000 em 2006 para 10,3/100.000 em 2017; entre crianças < 15 anos, de 6,94 para 3,20/100.000. A queda foi consistente em todas a regiões brasileiras e em todas as categorias de raça/etnicidade. Até 2017, 70,2% dos casos eram multibacilares, 30,5% apresentavam incapacidades físicas grau 1 (G1D) ou grau 2 (G2D) ao diagnóstico e 42,8% não foram avaliados ao encerramento do tratamento ou alta; os casos com G2D ao diagnóstico foram detectados majoritariamente nas áreas urbanas (80%), e 5% dos casos faleceram durante o tratamento (devido à hanseníase ou por outras causas). Embora a frequência da TDCN da hanseníase tenha diminuído no Brasil entre 2006 e 2017 em todos os grupos avaliados, o número grande de casos com hanseníase multibacilar, incapacidades físicas ou sem avaliação adequada e entre crianças sugere a necessidade de reforçar o diagnóstico e tratamento oportunos para controlar a hanseníase no Brasil.

Resumen: Se realizó este trabajo con el fin de describir la tendencia general y en subgrupos de la tasa de detección de nuevos casos de lepra (NCDR por sus siglas en inglés) en Brasil, entre 2006-2017, así como para analizar la evolución de las características clínicas y de tratamiento de los pacientes, con énfasis en los casos diagnosticados con un grado 2 de discapacidad física. Realizamos un estudio descriptivo para analizar los nuevos casos de lepra registrados en el Sistema Brasileño de Información de Enfermedades de Notificación (SINAN), 2006-2017. Calculamos la NCDR de lepra por cada 100.000 habitantes (general e individuos con una edad < 15 y ≥ 15 años) por sexo, edad, raza/etnicidad, áreas urbanas/rurales y regiones brasileñas, y estimamos las tendencias usando el test no paramétrico de Mann-Kendall. Analizamos las distribuciones de casos según las características clínicas relevantes a lo largo del tiempo. En Brasil, hubo una drástica disminución en general de NCDR de los 23,4/100.000 en 2006, a los 10,3/100.000 en 2017; entre niños < 15 años, desde los 6,94 a los 3,20/100.000. El decremento fue consistente en todas las regiones brasileñas y categorías de raza/etnicidad. En 2017, un 70,2% de los casos fueron multibacilares, un 30,5% tenían grado 1 (G1D) o 2 (G2D) discapacidad física en el diagnóstico y un 42,8% no fueron evaluados al completar el tratamiento/ser dados de alta; casos con G2D en el diagnóstico fueron en su mayoría detectados en áreas urbanas (80%) y un 5% de los casos murieron durante el tratamiento (lepra u otras causas). A pesar de la frecuencia de lepra los NCDR decrecieron en Brasil de 2006 a 2017, a través de todos los grupos de población evaluados, el elevado número de casos con lepra multibacilar, discapacidad física o sin una adecuada evaluación, y entre niños sugiere la necesidad de reforzar a tiempo el diagnóstico y tratamiento para controlar la lepra en Brasil.

Associated factors to spatial variation of pregnancy in adolescence in Brazil, 2014: ecological study of spatial aggregates / Factores asociados a la variación espacial del embarazo en la adolescencia en Brasil, 2014: estudio ecológico de agregados espaciales / Fatores associados à variação espacial da gravidez na adolescência no Brasil, 2014: estudo ecológico de agregados espaciais

Objective. To identify socioeconomic and health care determinants of the spatial variation of teenage pregnancy in Brazil in 2014. Methods. Spatial ecological study with municipalities as units of analysis. Spatial linear regression was used to verify the association between fertility in adolescence (15-19 years) and socioeconomic and health variables. Results. Fertility rate in adolescence was negatively associated with greater coverage of the Family Health Strategy (ß = -0.011 ­ 95%CI -0.017;-0.005), an adequate number of prenatal consultations (ß = -0.122 ­ 95%CI -0.132;-0.224) and low per capita average family income (ß = -0.104 ­ 95%CI -0.105;-0.103). This association was positive in relation to the Gini index (ß = 7.031 ­ 95%CI 95%CI 4.793;9.269), low income (ß = 0.127 ­ 95%CI 0.108;0.145), household crowding (ß = 6.292 ­ 95%CI 5.062;7.522) and less education (ß = 0.260 ­ 95%CI 0.224;0.295). Conclusion. Lack of access to primary care and lower income are associated with higher fertility in adolescence. Worse socioeconomic and health care indicators are associated with higher fertility rate in adolescence.

Incidence of and Factors Associated With Leprosy Among Household Contacts of Patients With Leprosy in Brazil.

Importance: Despite progress toward reducing global incidence, leprosy control remains a challenge in low- and middle-income countries. Objective: To estimate new case detection rates of leprosy among household contacts of patients with previously diagnosed leprosy and to investigate its associated risk factors. Design, Setting, and Participants: This population-based cohort study included families registered in the 100 Million Brazilian Cohort linked with nationwide registries of leprosy; data were collected from January 1, 2007, through December 31, 2014. Household contacts of patients with a previous diagnosis of leprosy from each household unit were followed up from the time of detection of the primary case to the time of detection of a subsequent case or until December 31, 2014. Data analysis was performed from May to December 2018. Exposures: Clinical characteristics of the primary case and sociodemographic factors of the household contact. Main Outcomes and Measures: Incidence of leprosy, estimated as the new case detection rate of leprosy per 100 000 household contacts at risk (person-years at risk). The association between occurrence of a subsequent leprosy case and the exposure risk factors was assessed using multilevel mixed-effects logistic regressions allowing for state- and household-specific random effects. Results: Among 42 725 household contacts (22 449 [52.5%] female; mean [SD] age, 22.4 [18.5] years) of 17 876 patients detected with leprosy, the new case detection rate of leprosy was 636.3 (95% CI, 594.4-681.1) per 100 000 person-years at risk overall and 521.9 (95% CI, 466.3-584.1) per 100 000 person-years at risk among children younger than 15 years. Household contacts of patients with multibacillary leprosy had higher odds of developing leprosy (adjusted odds ratio [OR], 1.48; 95% CI, 1.17-1.88), and the odds increased among contacts aged 50 years or older (adjusted OR, 3.11; 95% CI, 2.03-4.76). Leprosy detection was negatively associated with illiterate or preschool educational level (adjusted OR, 0.59; 95% CI, 0.38-0.92). For children, the odds were increased among boys (adjusted OR, 1.70; 95% CI, 1.20-2.42). Conclusions and Relevance: The findings in this Brazilian population-based cohort study suggest that the household contacts of patients with leprosy may have increased risk of leprosy, especially in households with existing multibacillary cases and older contacts. Public health interventions, such as contact screening, that specifically target this population appear to be needed.

Nutritional aspects of people affected by leprosy, between 2001 and 2014, in semi-arid Brazilian municipalities. / Aspectos nutricionais de pessoas acometidas por hanseníase, entre 2001 e 2014, em municípios do semiárido brasileiro.

The study aimed to characterize food insecurity, nutritional status, and eating habits of people affected by leprosy. This is a descriptive cross-sectional study based on a census population. We evaluated 276 cases, reported in the Notifiable Diseases Information System, between 2001 and 2014, in the municipalities of Vitória da Conquista and Tremedal, in the state of Bahia. Food insecurity was estimated according to the Brazilian Food Insecurity Scale. We collected weight and height measurements, meal frequency, and household, socioeconomic, psychosocial and clinical variables. The prevalence of food insecurity was 41.0% among the study population - 28.3% mild, 8.0% moderate and 4.7% severe. Overweight/obesity was estimated in 60.1% of the study participants, and excessive salt intake was reported by 8.6%. Beans and red meat were the most regularly consumed foods; there was low consumption of milk, raw and cooked vegetables, and fruits. This population presented high food insecurity prevalence, inadequate eating habits and nutritional status, reflecting nutritional vulnerability. The insertion of nutritional assistance in the leprosy control programmes is recommended, to improve health care.

O estudo buscou caracterizar a insegurança alimentar, o estado nutricional e os hábitos alimentares de pessoas acometidas por hanseníase. Trata-se de um estudo transversal descritivo, de população censitária, em que foram avaliados 276 casos, notificados no Sistema de Informação de Agravos de Notificação, entre 2001 e 2014, nos municípios de Vitória da Conquista e Tremedal, Bahia. Na análise foi empregada a Escala Brasileira de Insegurança Alimentar. Foram coletadas medidas de peso e altura, frequência alimentar, variáveis domiciliares, socioeconômicas, psicossociais e clínicas. A prevalência de insegurança alimentar foi de 41,0% na população; sendo 28,3% leve, 8,0% moderada e 4,7% grave. O sobrepeso/obesidade foi estimado em 60,1% das pessoas avaliadas e o consumo excessivo de sal foi relatado por 8,6%. O feijão e a carne vermelha foram os alimentos mais regularmente consumidos e houve baixo consumo de leite, hortaliças cruas e cozidas e frutas. A insegurança alimentar apresentou elevada prevalência, associada à inadequação do hábito alimentar e estado nutricional, refletindo a vulnerabilidade nutricional desta população. Recomenda-se a inserção da assistência nutricional às políticas públicas da hanseníase, como forma de qualificar a atenção à saúde.
