Migração e mortalidade por câncer entre os migrantes colombianos nos EUA: um estudo com dados de declaração de óbito / Migration and cancer mortality among Colombian migrants in the USA: a death certification study

Resumo Este estudo teve como objetivo comparar padrões de mortalidade por câncer entre os imigrantes colombianos nos EUA e colombianos em sua terra natal. Dados de 2008 a 2012 foram coletados, e foram calculadas taxas de mortalidade por câncer de colombianos residindo em seu país natal e colombianos residindo em Califórnia, Flórida e Nova York, bem como taxas específicas de mortalidade por idade e sexo por cada 100.000 pessoas. Para comparar as duas populações, tanto antes como após a correção pela escolaridade, as razões de taxas de mortalidade (MRR) foram estimadas por modelo de regressão binomial negativa. Foi descoberto que colombianos em sua terra natal apresentam taxas de mortalidade por câncer mais altas quando comparados aos que residem nos EUA (MRR masculino 1,4 (IC 95%: 1,2-1,5), MRR feminino 1,5 (IC 95%: 1,3-1,7)). Essas diferenças persistem para a maioria dos tipos de câncer, mesmo após correção pela escolaridade. Os colombianos em sua terra natal apresentaram taxa de mortalidade por câncer gástrico (MRR masculino 2,6; feminino 2,8) e cervical (MRR 5,0) significativamente mais alta em comparação com os que residem nos EUA. As desigualdades educacionais na mortalidade por câncer foram mais acentuadas para aqueles que moram em sua terra natal. A menor taxa de mortalidade por câncer observada entre os colombianos nos EUA, porém, não pode ser atribuída às diferenças de escolaridade, um indicador de status socioeconômico. Em vez disso, provavelmente ocorre devido à maior acessibilidade aos serviços de saúde preventivos e curativos nos EUA.

Abstract We aim to compare cancer mortality rates of USA Colombian migrants (USA Colombians) to Colombians in their country of origin (CO Colombians). Using Colombian national mortality data and data on cancer deaths among Colombians residing in the states of California, Florida, and New York (USA Colombians) for the period 2008-2012, we estimated sex-specific and age-standardized mortality rates (ASMR), expressed per 100,000 persons. For comparisons between the two populations before and after adjustment for educational level, negative binomial regression models were used to compute Mortality Rate Ratios (MRR). CO Colombians had higher cancer mortality rates compared with USA Colombians (male MRR 1.4 [95%CI: 1.2-1.5], female MRR 1.5 [95%CI: 1.3-1.7]). These differences persisted for most cancers even after adjustment for education. CO Colombians had significantly higher mortality from gastric (MRR 2.6 in males and 2.8 in females) and cervical cancer (MRR 5.0) compared with US Colombians. Educational inequalities in cancer mortality were more pronounced among CO Colombians than among USA Colombians. Lower cancer mortality observed among USA Colombians cannot be attributed to differences in education, an indicator of socio-economic status. Rather, it is likely due to better access to preventive and curative healthcare in the USA.

Infant mortality in the municipality of São Paulo: trend and social inequality (2006-2019).

OBJECTIVE: Considering the published evidence on the impact of recent economic crises and the implementation of fiscal austerity policies in Brazil on various health indicators, this study aims to analyze how the trend and socio-spatial inequality of infant mortality behaved in the municipality of São Paulo from 2006 to 2019. METHODS: This is an ecological study with a temporal trend analysis that was developed in municipality of São Paulo, using three residence area strata differentiated according to their social vulnerability following the 2010 São Paulo Social Vulnerability Index. Infant mortality rate, as well as neonatal, and post-neonatal mortality rates, were calculated for each social vulnerability stratum, each year in the period, and for the first and last three triennia. Temporal trends were analyzed by the Prais-Winsten regression model and inequality magnitude, by rate ratios. RESULTS: We found a decline in infant mortality rate and its components from 2006 to 2015, greater in the stratum with low social vulnerability and in the post-neonatal period when compared to the neonatal one. This decline ended in 2015, stagnating in the next period (2016-2019). Our analysis of infant mortality inequality across social vulnerability stratum showed a significant increase from the initial to the final triennia in the analyzed period; rate ratios increased from 1.36 to 1.48 in the high stratum (compared to the low social vulnerability stratum), and from 1.19 to 1.32 between the medium and low social vulnerability strata. CONCLUSIONS: The observed stagnation of infant mortality rate decline in 2015 and the increase in socio-spatial inequality point to the urgent need to reformulate current public policies to reverse this situation and reduce inequalities in the risk of infant death.

Social inequalities in male cancer in a metropolis in the Southeast region of Brazil.

OBJECTIVE: To analyze inequalities in incidence, mortality, and estimated survival for neoplasms in men according to social vulnerability. METHODS: Analysis of cases and deaths of all neoplasms and the five most common in men aged 30 years or older in the city of Campinas (SP), between 2010 and 2014, using data from the Population-Based Cancer Registry (RCBP) and the Mortality Information System (SIM). The areas of residence were grouped into five social vulnerability strata (SVS) using São Paulo Social Vulnerability Index. For each SVS, age-standardized incidence and mortality rates were calculated. A five-year survival proxy was calculated by complementing the ratio of the mortality rate to the incidence rate. Inequalities between strata were measured by the ratios between rates, the relative inequality index (RII) and the angular inequality index (AII). RESULTS: RII revealed that the incidence of all neoplasms (0.66, 95%CI 0.62-0.69) and colorectal and lung cancers were lower among the most socially vulnerable, who presented a higher incidence of stomach and oral cavity cancer. Mortality rates for stomach, oral cavity, prostate and all types of cancer were higher in the most vulnerable segments, with no differences in mortality for colorectal and lung cancer. Survival was lower in the most social vulnerable stratum for all types of cancer studied. AII showed excess cases in the least vulnerable and deaths in the most vulnerable. Social inequalities were different depending on the tumor location and the indicator analyzed. CONCLUSION: There is a trend of reversal of inequalities between incidence-mortality and incidence-survival, and the most social vulnerable segment presents lower survival rates for the types of cancer, pointing to the existence of inequality in access to early diagnosis and effective and timely treatment.

Educational inequalities in heart failure mortality and the cycles of the internal armed conflict in Colombia: An observational panel study of ecological data, 1999-2017.

Heart failure (HF) is a significant clinical problem and an important public health issue due to the morbidity and mortality that it causes, especially in a population that is aging and affected by social stressors such as armed conflict. We aim to describe the inequalities and trends of HF mortality by educational level in Colombia between 1999 and 2017 compared with the cycles of the internal armed conflict during the same period. An observational study of ecological data panels, with aggregates at the national level, was conducted. Information from death certificates with HF as the basic cause of death (COD) was used. Variables of the year of death, sex, age, department of residence, and educational level were considered. Mortality rates adjusted for age were calculated. A joinpoint regression was used to model the trend of rates by educational level. We found that both men and women with primary education had the highest adjusted mortality rates: among men, RR_primary = 19.06 deaths/100,000 inhabitants, SE = 0.13 vs. RR_tertiary = 4.85, SE = 0.17, and similar differences among women. Mortality rates tended to decrease at all educational levels, with a greater reduction in people with higher educational levels. In both sexes, the behavior of the relative index of inequality showed significant inequality, albeit with a strong reduction during the last decade. Mortality due to HF in Colombia shows inequalities by educational level. In the prevention of HF, education should be considered a structural social determinant. In addition, we analyzed the potential role of the Colombian long-term armed conflict in the observed trends. We highlighted the role of the health sector, together with other sectors (education, work, and housing), in developing intersectoral public policies that contribute to the reduction of cardiovascular mortality disparities.

Inequalities in infant vaccination coverage during the COVID-19 pandemic: A population-based study in Peru.

OBJECTIVE: To identify the associated factors and assess the inequalities of full vaccination coverage (FVC) among Peruvian infants aged 12-23 months during the COVID-19 pandemic in a nationally representative sample. METHODS: We carried out a population-based cross-sectional study based on a secondary data analysis using the 2021 Peruvian Demographic Health Survey (DHS) in infants aged 12 to 23 months. The sampling design was probabilistic, multistage, stratified, and independent at both departmental and area of residence levels. FVC was defined according to the WHO definition. We performed generalized linear models (GLM) Poisson family log link function to estimate crude (aPR) and adjusted prevalence ratios (aPR). Also, for inequality assessment, we calculated the concentration curve (CC), concentration index (CI), and Erreygers normalized concentration index (ECI). RESULTS: We included 4,189 infants in our analysis. Nationwide, the prevalence of FVC was 66.19% (95% CI: 64.33-68). Being younger, having a mother with no education or primary education, belonging to a large family, having no access to mass media, having had six or fewer ANC visits, and having a mother whose age was under 20 at first delivery were inversely associated with FVC. Meanwhile, living in the Highlands or on the rest of the coast, and living in rural areas were directly associated with FVC. We found a pro-rich inequality in FVC based on wealth-ranked households (CI: 0.0066; ECI: 0.0175). CONCLUSION: FVC has dropped among Peruvian infants aged between 12 and 23 months. There were several factors associated with FVC. It was more concentrated among the better-off infants, although in low magnitude.

Social inequalities in male cancer in a metropolis in the Southeast region of Brazil / Desigualdades sociais em câncer no sexo masculino em uma metrópole da região Sudeste do Brasil

RESUMO OBJETIVO Analisar as desigualdades segundo a vulnerabilidade social na incidência, mortalidade e estimativa de sobrevida de neoplasias no sexo masculino. MÉTODOS Foram analisados os casos e as mortes do total de neoplasias e das cinco mais incidentes em homens com 30 anos ou mais no município de Campinas (SP), entre 2010 e 2014, utilizando dados do Registro de Câncer de Base Populacional (RCBP) e do Sistema de Informação sobre Mortalidade (SIM). As áreas de residência foram agrupadas em cinco estratos de vulnerabilidade social (EVS) utilizando o Índice Paulista de Vulnerabilidade Social. Para cada EVS, foram calculadas as taxas de incidência e de mortalidade padronizadas por idade. Um proxy de sobrevida em cinco anos foi calculado pelo complemento da razão da taxa de mortalidade pela taxa de incidência. As desigualdades entre os estratos foram mensuradas pelas razões entre taxas, pelo índice relativo de desigualdade (IRD) e pelo índice angular de desigualdade. RESULTADOS O IRD revelou que a incidência do total de neoplasias (0,66, IC95% 0,62-0,69) e dos cânceres colorretal e de pulmão foram menores entre os socialmente mais vulneráveis, que apresentaram maior incidência dos cânceres de estômago e da cavidade oral. As taxas de mortalidade por câncer de estômago, cavidade oral, próstata e por todas as neoplasias foram superiores nos segmentos mais vulneráveis, sem diferenças na mortalidade por câncer colorretal e de pulmão. A sobrevida foi menor no estrato de maior vulnerabilidade social para todos os cânceres estudados. O índice angular de desigualdade (IAD) mostrou o excesso de casos nos menos vulneráveis e de óbitos nos mais vulneráveis. As desigualdades sociais revelaram-se distintas conforme a localização do tumor e o indicador analisado. CONCLUSÃO Constata-se uma tendência de inversão das desigualdades entre incidência e mortalidade e sobrevida, sendo esta última desfavorável ao segmento de maior vulnerabilidade social para os tipos de câncer, apontando a existência de inequidade no acesso ao diagnóstico precoce e ao tratamento efetivo e oportuno.

RESUMO OBJETIVO Considerando as evidências publicadas sobre o impacto de crises econômicas e da implementação de políticas de austeridade fiscal em vários indicadores de saúde, e a ocorrência recente desses eventos no Brasil, o objetivo deste estudo foi analisar o comportamento da tendência e da desigualdade socioespacial da mortalidade infantil no município de São Paulo, entre 2006 e 2019. MÉTODOS Trata-se de estudo ecológico de análise de tendência temporal, desenvolvido no município de São Paulo e em três estratos de áreas de residência, diferenciadas segundo nível de vulnerabilidade social, a partir do Índice Paulista de Vulnerabilidade Social de 2010. Calcularam-se as taxas de mortalidade infantil, neonatal e pós-neonatal para cada um dos estratos de vulnerabilidade social, para cada ano do período e para o primeiro e o último triênios. A tendência temporal foi analisada com o modelo de regressão de Prais-Winsten e a magnitude da desigualdade avaliada pelas razões de taxas. RESULTADOS O declínio das taxas de mortalidade infantil e de seus componentes, observado entre 2006 e 2015, que foi mais elevado no estrato de baixa vulnerabilidade social e no período pós-neonatal em comparação ao neonatal, foi interrompido em 2015, com estagnação das taxas no período subsequente (2016-2019). A análise da desigualdade da mortalidade infantil entre os estratos de vulnerabilidade social revelou aumento significativo entre os triênios inicial e final do período analisado; as razões de taxas cresceram de 1,36 para 1,48 entre o estrato de alta em relação ao de baixa vulnerabilidade social e de 1,19 para 1,32 entre o de média e de baixa vulnerabilidade social. CONCLUSÕES O estancamento do declínio da taxas de mortalidade infantil em 2015 e o aumento da desigualdade socioespacial observados apontam para a necessidade premente de reformulação das políticas públicas vigentes para reversão desse quadro, visando reduzir a iniquidade presente no risco de morte infantil.

Educational level and tuberculosis mortality in Colombia: growing inequalities and stagnation in reduction.

We aim to describe the role of educational inequalities, for sex and age groups, in adult tuberculosis (TB) mortality in Colombia, 1999-2017. We linked mortality data to data estimation of the national population based on censuses and surveys to obtain primary, secondary, and tertiary adult (25+ years of age) age-standardized mortality rates (ASMR) by educational level. Thus, a population-based study was conducted using national secondary mortality data between 1999 and 2017. Tuberculosis age-standardized mortality rates were calculated separately by educational level, sex, and age groups, using Poisson regression models. Educational relative inequalities in adult mortality were evaluated by calculating the rate ratio, and the relative index of inequality (RII). Trends and joinpoints were evaluated by annual percentage change (APC). We found that, out of the 19,720 TB deaths reported, 69% occurred in men, and 45% in older adults (men and women, aged 65+). Men presented higher TB mortality rates than women (ASMR men = 7.1/100,000 inhabitants, ASMR women = 2.7/100,000 inhabitants). As mortality was consistently higher in the lowest educational level for both sexes and all age groups, inequalities in TB mortality were found to be high (RII = 9.7 and 13.4 among men and women, respectively) and growing at an annual rate of 8% and 1%. High and increasing inequalities, regarding educational level, in TB mortality in Colombia suggest the need to comprehensively address strategies for reducing TB by considering social determinants and including health education strategies throughout the country.

Pretendemos describir el papel de las inequidades educacionales, según sexo y grupos de edad, en la mortalidad de adultos por tuberculosis (TB) en Colombia, 1999-2017. Relacionamos datos de mortalidad con la estimación de datos de la población nacional, basada en censos y encuestas, con el fin de obtener las tasas de mortalidad primarias, secundarias, y terciarias de adultos (25+ años) estandarizadas por edad, según el nivel educativo. Se realizó un estudio basado en población, usando datos de mortalidad nacional secundaria entre 1999 y 2017. Las tasas de mortalidad por tuberculosis estandarizadas por edad (ASMR), fueron calculadas separadamente por nivel educacional, sexo, y grupos de edad, usando modelos de regresión de Poisson. Las inequidades educacionales relacionadas con la mortalidad en adultos fueron evaluadas calculando el cociente de tasas, y el índice de inequidad relacionado (RII). Se evaluaron tendencias y joinpoints mediante la variación porcentual anual (APC). Se descubrió que, de las 19.720 muertes informadas por TB, un 69% se produjeron en hombres, y un 45% en hombres y mujeres adultos mayores (65+). Los hombres presentaron tasas de mortalidad más altas por TB que las mujeres (ASMR hombres = 7,1/100.000 habitantes, ASMR mujeres = 2,7/100.000 habitantes). Asimismo, la mortalidad fue consistentemente más alta en los niveles educacionales más bajos y ambos sexos, además en todos los grupos de edad existieron inequidades altas en la mortalidad por TB (RII = 9,7 y 13,4 entre hombres y mujeres, respectivamente) y creciendo a una tasa anual de un 8% y 1%. Las altas y crecientes inequidades por nivel educacional en la mortalidad por TB en Colombia apuntan la necesidad de dirigir estrategias que reduzcan la TB ampliamente, tomando en consideración determinantes sociales e incluyendo estrategias de educación en salud en todo el país.

O estudo tem como objetivo descrever o papel das desigualdades educacionais por gênero e grupo etário na mortalidade por tuberculose (TB) em adultos colombianos entre 1999 e 2017. Relacionamos os dados de mortalidade com as estimativas da população nacional, com base nos censos demográficos e inquéritos para obter as taxas de mortalidade padronizadas por idade (TMPI), primárias, secundárias e terciárias, em adultos com 25 anos ou mais, de acordo com o nível de escolaridade. Foi realizado um estudo populacional com o uso de dados de mortalidade secundários entre 1999 e 2017. Foram utilizados modelos de regressão Poisson para calcular separadamente as taxas de mortalidade por tuberculose padronizadas por idade, de acordo com o nível de escolaridade, sexo e grupo etário. As desigualdades educacionais relativas na mortalidade em adultos foram avaliadas pelo cálculo da razão de taxas e o índice relativo de desigualdade (IRD). Foram avaliadas as tendências e os joinpoints através da mudança percentual anual média (APC). Entre os 19.720 óbitos por TB notificados, 69% ocorreram em homens e 45% em homens e mulheres adultos (65+). Os homens apresentaram taxas de mortalidade por TB maiores que as mulheres (TMPI masculina = 7,1/100.000 habitantes, TMPI feminina = 2,7/100.000 habitantes). A mortalidade era mais alta no nível mais baixo de escolaridade em ambos os sexos e em todos os grupos etários, portanto, as desigualdades na mortalidade por TB eram altas (IRD = 9,7 e 13,4 em homens e mulheres, respectivamente), com crescimento anual de 8% e 1%. As desigualdades altas e crescentes na mortalidade por TB de acordo com o nível de escolaridade na Colômbia sugerem a necessidade de adotar estratégias abrangentes para reduzir a carga da tuberculose, levando em conta os determinantes sociais e incluindo estratégias nacionais de educação em saúde.

Educational inequalities in suicide in a middle-income country: A socioeconomic approach of mental health.

OBJECTIVE: This research aims to describe trends in inequalities in suicide mortality by educational level in Colombia between 1998 and 2015. METHOD: Standardized suicide mortality rates (SMR) were calculated by educational level, sex, and age in adult men and women over 25 years of age. Poisson regression models were used to calculate the RR (rate ratio) with those highly educated as a reference, and the RII (relative index of inequality). RESULTS: The number of reported deaths by suicide between 1998 and 2015 was 24,654, of which 84.7% were men. By age-group, 48.5% of suicides were among young adult men and women (25-44). Men had higher suicide rates than women (SMR men = 10.44/100,000; SMR women = 1.72/100,000). The age-standardized mortality rates (SMR) were higher in the groups with the lowest educational level in both sexes and all age-groups, except for senior adult women (65+). Broadly, while SMR reduced throughout most of the period, inequalities grew. CONCLUSIONS: We found that the educational inequities associated with suicide in Colombia grew slightly. This suggests the need to work on suicide prevention strategies that go beyond the individual risk factors. Socioeconomic issues need to be considered as a key tool to prevent suicide by improving peoples' quality of life and their mental health.

Ethnicity and Low Birth Weight: Inequalities Between Ethnic Minorities and the Predominant Mestizo Population, Colombia, 2008-2014.

Low birth weight (LBW) is a global problem that annually affects nearly 20 million children, 96% of these in developing countries. According to the WHO, the poorest and the ethnic minorities are the groups most affected by this indicator. A cross-sectional study of the database of all newborns officially registered in Colombia in 2008-2014 was done. While dichotomizing the mestizo population and ethnic minorities (Afro-descendants, indigenous, ROM), normal and low birth weight was used as the dependent variable and ethnicity as the explanatory variable. Other variables of the parents and the newborns were used as covariates. To assess associations, bivariate and multivariate logistic regression analyses were performed. The incidence of LBW among newborns registered in Colombia fluctuated at around 9%. Among the ethnic minorities, the probability of LBW, adjusted for other variables, was significantly higher (OR 1.07, 95% CI 1.05-1.08) than among mestizos. A significantly higher risk of LBW to newborns in the ethnic minorities' group, and those with unfavorable socioeconomic conditions, was found.

RESUMEN: El bajo peso al nacer (BPN) es un problema global que afecta anualmente a casi 20 millones de niños, el 96% de estos en países en desarrollo. Según la OMS, las más pobres y las minorías étnicas son los grupos más afectados por este indicador. Se realizó un estudio transversal de la base de datos de todos los recién nacidos registrados oficialmente en Colombia en 2008-2014. La población fue dicotomizaba en mestiza y minorías étnicas (afrodescendientes, indígenas, ROM). Se utilizó Bajo Peso al Nacer (BPN) como variable dependiente y el origen étnico como variable explicativa. Otras variables de los padres y los recién nacidos se utilizaron como covariables. Para evaluar las asociaciones, se realizaron análisis de regresión logística bivariada y multivariada. La incidencia de BPN entre los recién nacidos registrados en Colombia fluctuó alrededor del 9%. Entre las minorías étnicas, la probabilidad de LBW, ajustada por otras variables, fue significativamente mayor (OR = 1.07, 95% _CI: 1.05-1.08) que entre los mestizos. Se encontró un riesgo significativamente más alto de BPN para los recién nacidos en el grupo de minorías étnicas y aquellos con condiciones socioeconómicas desfavorables.

Time trends of diabetes in Colombia from 1998 to 2015: the recent stagnation in mortality, and educational inequities.

AIMS: To study the observed trends in Diabetes Mellitus (DM) mortality rates according to educational level, age group and sex in Colombia between 1998 and 2015. METHODS: A cross-sectional study was conducted based in official databases. Age-standardized mortality rates were calculated by age-gropus, educational level, sex and year. Rate Ratios (RR) were estimated with higher educational level as reference. The Relative Index of Inequality (RII) was estimated. Joinpoint regressions were applied to identify inflexion points in mortality trends, and Percent Annual Change (APC) between inflexion points. RESULTS: 124,198 deaths caused by DM among adults (25+ years) were analysed, 57% among women (71,093); 74% of deaths occurred among those older than 45 years, especially senior adults (65+). The highest adjusted mortality rates were for those with primary and secondary educational levels. The highest mortality occurred in adult women (65 years or more) with primary education level. Relative Index of Inequality was higher for women than for men along the period. CONCLUSIONS: Educational levels were found to be strongly associated with death by DM in adults (25+). Intersectoral actions are required to influence the risk factors and to improve the treatment of the disease in groups with lower levels of education.

Education and pneumonia mortality: a trend analysis of its inequalities in Colombian adults.

OBJECTIVE: To explore the existence and trends of social inequalities related to pneumonia mortality in Colombian adults using educational level as a proxy of socioeconomic status. METHODS: We obtained individual and anonymised registries from death certificates due to pneumonia for 1998-2015. Educational level data were gathered from microdata of the Colombian Demography Health Surveys. Rate ratios (RR) were estimated by using Poisson regression models, comparing mortality of educational groups with mortality in the highest education group. Relative index of inequality (RII) was measured to assess changes in disparities, regressing mortality on the midpoint of the cumulative distribution of education, thereby considering the size of each educational group. RESULTS: For adults 25+ years, the risk of dying was significantly higher among lower educated. The RRs depict increased risks of dying comparing lower and highest education level, and this tendency was stronger in woman than in men (RR for primary education=2.34 (95% CI 2.32 to 2.36), RR for secondary education=1.77 (95% CI 1.75 to 1.78) versus RR for primary education=1.83 (95% CI 1.81 to 1.85), RR for secondary education=1.51 (95% CI 1.50 to 1.53)). According to age groups, young adults (25-44 years) showed the largest inequality in terms of educational level; RRs for pneumonia mortality regarding the tertiary educated groups show increased mortality in the lower and secondary educated, and these differences decreased with ages. RII in pneumonia mortality among adult men was 2.01 (95% CI 2.00 to 2.03) and in women 2.46 (95% CI 2.43 to 2.48). The RII was greatest at young ages, for both sexes. Time trends showed steadily significant increases for RII in both men and women (estimated annual percentage change (EAPC)men=3.8; EAPCwomen=2.6). CONCLUSION: A significant increase on the educational inequalities in mortality due to pneumonia during all period was found among men and women. Efforts to reduce pneumonia mortality in adults improving population health by raising education levels should be strengthened with policies that assure widespread access to economic and social opportunities.

How Educational Inequalities in Cardiovascular Mortality Evolve While Healthcare Insurance Coverage Grows: Colombia, 1998 to 2015.

OBJECTIVES: We aim to explore how the current increase in Healthcare Insurance Coverage in Colombia potentially affected educational inequalities in cardiovascular disease (CVD) mortality from 1998 to 2015. METHODS: The official death database for the period 1998 to 2015, codified by cause of death for CVD (International Classification of Diseases, Tenth Revision: I00-I99) was analyzed (men = 279 537, women = 292 122). We compared Healthcare Insurance Coverage (HIC) fluctuations with the trends and annual percentage changes (APCs) in CVD age-standardized mortality rates (ASMRs), the rate ratios of the ASMR to educational level, and the Relative Index of Inequality (RII), which was used to measure the educational inequalities. RESULTS: Mortality from CVD is higher in men than in women (ASMR/men = 148.2; 95% CI: 147.6-148.7 vs ASMR/women = 139.4; 95% CI: 138.9-139.9). People with a lower educational level have an increased risk of dying prematurely owing to CVD, the higher inequalities being those for young women (RII = 2.62; 95% CI: 2.60-2.64). Inequalities by educational level (APC of the RII) grew at a rate of 2.5% per year in men and 1.7% in women, despite the steady increase of HIC throughout the period. From 1998 to 2011, there was a significant decrease in mortality rates owing to CVD (APC = -2.4% and APC = -2.1% for men and women, respectively). As of 2011, there was an increase only for men (APC = +3.9%). CONCLUSIONS: In Colombia, educational inequalities could be a cause of the worrying increase in mortality caused by CVD, which affects women more than men, whereas the HIC seem to be ineffective at reducing educational inequalities, and therefore mortality by CVD.

Trends of Rural/Urban Homicide in Colombia, 1992-2015: Internal Armed Conflict and Hints for Postconflict.

OBJECTIVE: To analyze the relationship between rural and urban homicide rates in Colombia between 1992 and 2015 and the fluctuations in these rates. METHODS: Individual records of homicides and population aggregates in men and women aged 15-64 years were used. The adjusted rates of annual homicides were calculated for urban/rural areas and standardized by age. Rate Ratios (RRs) adjusted by region were calculated. A joinpoint analysis was performed to identify inflection points and the Annual Percentage Change (APC). RESULTS: Four joinpoints were identified in rural and urban rates: after peaking in 1992, homicide rates fell until 1997, and then increased until 2002. From this point on there was a continuous reduction until 2015, although this reduction slowed down from 2005 onward. During almost the whole period, the rates of rural homicides were higher than those of urban homicides, although they equalized at the end of the period. CONCLUSIONS: Unlike in other countries, during the study period Colombian homicide rates, which coincided with the dynamics of the armed conflict, were higher in rural than in urban areas. In recent years, a predominance of urban homicides committed by younger men has been identified, which could pose a challenge to postconflict in Colombia.

Health insurance coverage, neonatal mortality and caesarean section deliveries: an analysis of vital registration data in Colombia.

BACKGROUND: Low-income and middle-income countries have introduced different health insurance schemes over the past decades, but whether different schemes are associated with different neonatal outcomes is yet unknown. We examined the association between the health insurance coverage scheme and neonatal mortality in Colombia. METHODS: We used Colombian national vital registration data, including all live births (2 506 920) and neonatal deaths (17 712) between 2008 and 2011. We used Poisson regression models to examine the association between health insurance coverage and the neonatal mortality rate (NMR), distinguishing between women insured via the contributory scheme (40% of births, financed through payroll and employer's contributions), government subsidised insurance (47%) and the uninsured (11%). RESULTS: NMR was lower among babies born to mothers in the contributory scheme (6.13/1000) than in the subsidised scheme (7.69/1000) or the uninsured (8.38/1000). Controlling for socioeconomic and demographic factors, NMRs remained higher for those in the subsidised scheme (OR 1.09, 95% CI 1.05 to 1.14) and the uninsured (OR 1.16, 95% CI 1.10 to 1.23) compared to those in the contributory scheme. These differences increased in models that additionally controlled for caesarean section (C-section) delivery. This increase was due to the higher fraction of C-section deliveries among women in the contributory scheme (49%, compared to 34% for the subsidised scheme and 28% for the uninsured). CONCLUSIONS: Health insurance through the contributory system is associated with lower neonatal mortality than insurance through the subsidised system or lack of insurance. Universal health insurance may not be sufficient to close the gap in newborn mortality between socioeconomic groups.

Time trends in educational inequalities in cancer mortality in Colombia, 1998-2012.

OBJECTIVES: To evaluate trends in premature cancer mortality in Colombia by educational level in three periods: 1998-2002 with low healthcare insurance coverage, 2003-2007 with rapidly increasing coverage and finally 2008-2012 with almost universal coverage (2008-2012). SETTING: Colombian population-based, national secondary mortality data. PARTICIPANTS: We included all (n=188,091) cancer deaths occurring in the age group 20-64 years between 1998 and 2012, excluding only cases with low levels of quality of registration (n=2902, 1.5%). PRIMARY AND SECONDARY OUTCOME MEASURES: In this descriptive study, we linked mortality data of ages 20-64 years to census data to obtain age-standardised cancer mortality rates by educational level. Using Poisson regression, we modelled premature mortality by educational level estimating rate ratios (RR), relative index of inequality (RII) and the Slope Index of Inequality (SII). RESULTS: Relative measures showed increased risks of dying among the lower educated compared to the highest educated; this tendency was stronger in women (RRprimary 1.49; RRsecondary 1.22, both p<0.0001) than in men (RRprimary 1.35; RRsecondary 1.11, both p<0.0001). In absolute terms (SII), cancer caused a difference per 100 000 deaths between the highest and lowest educated of 20.5 in males and 28.5 in females. RII was significantly higher among women and the younger age categories. RII decreased between the first and second periods; afterwards (2008-2012), it increased significantly back to their previous levels. Among women, no significant increases or declines in cancer mortality over time were observed in recent periods in the lowest educated group, whereas strong recent declines were observed in those with secondary education or higher. CONCLUSIONS: Educational inequalities in cancer mortality in Colombia are increasing in absolute and relative terms, and are concentrated in young age categories. This trend was not curbed by increases in healthcare insurance coverage. Policymakers should focus on improving equal access to prevention, early detection, diagnostic and treatment facilities.

The public health impact of economic fluctuations in a Latin American country: mortality and the business cycle in Colombia in the period 1980-2010.

INTRODUCTION: Studies in high-income countries suggest that mortality is related to economic cycles, but few studies have examined how fluctuations in the economy influence mortality in low- and middle-income countries. We exploit regional variations in gross domestic product per capita (GDPpc) over the period 1980-2010 in Colombia to examine how changes in economic output relate to adult mortality. METHODS: Data on the number of annual deaths at ages 20 years and older (n = 3,506,600) from mortality registries, disaggregated by age groups, sex and region, were linked to population counts for the period 1980-2010. We used region fixed effect models to examine whether changes in regional GDPpc were associated with changes in mortality. We carried out separate analyses for the periods 1980-1995 and 2000-2010 as well as by sex, distinguishing three age groups: 20-44 (predominantly young working adults), 45-64 (middle aged working adults), and 65+ (senior, predominantly retired individuals). RESULTS: The association between regional economic conditions and mortality varied by period and age groups. From 1980 to 1995, increases in GDPpc were unrelated to mortality at ages 20 to 64, but they were associated with reductions in mortality for senior men. In contrast, from 2000 to 2010, changes in GDPpc were not associated with old age mortality, while an increase in GDPpc was associated with a decline in mortality at ages 20-44 years. Analyses restricted to regions with high registration coverage yielded similar albeit less precise estimates for most sub-groups. CONCLUSIONS: The relationship between business cycles and mortality varied by period and age in Colombia. Most notably, mortality shifted from being acyclical to being countercyclical for males aged 20-44, while it shifted from being countercyclical to being acyclical for males aged 65+.

Trends in inequalities in premature cancer mortality by educational level in Colombia, 1998-2007.

BACKGROUND: There is a paucity of studies on socioeconomic inequalities in cancer mortality in developing countries. We examined trends in inequalities in cancer mortality by educational attainment in Colombia during a period of epidemiological transition and rapid expansion of health insurance coverage. METHODS: Population mortality data (1998-2007) were linked to census data to obtain age-standardised cancer mortality rates by educational attainment at ages 25-64 years for stomach, cervical, prostate, lung, colorectal, breast and other cancers. We used Poisson regression to model mortality by educational attainment and estimated the contribution of specific cancers to the slope index of inequality in cancer mortality. RESULTS: We observed large educational inequalities in cancer mortality, particularly for cancer of the cervix (rate ratio (RR) primary vs tertiary groups=5.75, contributing 51% of cancer inequalities), stomach (RR=2.56 for males, contributing 49% of total cancer inequalities and RR=1.98 for females, contributing 14% to total cancer inequalities) and lung (RR=1.64 for males contributing 17% of total cancer inequalities and 1.32 for females contributing 5% to total cancer inequalities). Total cancer mortality rates declined faster among those with higher education, with the exception of mortality from cervical cancer, which declined more rapidly in the lower educational groups. CONCLUSIONS: There are large socioeconomic inequalities in preventable cancer mortality in Colombia, which underscore the need for intensifying prevention efforts. Reduction of cervical cancer can be achieved through reducing human papilloma virus infection, early detection and improved access to treatment of preneoplastic lesions. Reinforcing antitobacco measures may be particularly important to curb inequalities in cancer mortality.

Socioeconomic inequalities in premature mortality in Colombia, 1998-2007: the double burden of non-communicable diseases and injuries.

OBJECTIVES: Non-communicable diseases have become the leading cause of death in middle-income countries, but mortality from injuries and infections remains high. We examined the contribution of specific causes to disparities in adult premature mortality (ages 25-64) by educational level from 1998 to 2007 in Colombia. METHODS: Data from mortality registries were linked to population censuses to obtain mortality rates by educational attainment. We used Poisson regression to model trends in mortality by educational attainment and estimated the contribution of specific causes to the Slope Index of Inequality. RESULTS: Men and women with only primary education had higher premature mortality than men and women with post-secondary education (RRmen=2.60, 95% confidence interval [CI]: 2.56, 2.64; RRwomen=2.36, CI: 2.31, 2.42). Mortality declined in all educational groups, but declines were significantly larger for higher-educated men and women. Homicide explained 55.1% of male inequalities while non-communicable diseases explained 62.5% of female inequalities and 27.1% of male inequalities. Infections explained a small proportion of inequalities in mortality. CONCLUSION: Injuries and non-communicable diseases contribute considerably to disparities in premature mortality in Colombia. Multi-sector policies to reduce both interpersonal violence and non-communicable disease risk factors are required to curb mortality disparities.
