RESUMO

BACKGROUND: Acute myocardial infarction (AMI) is the main cause of death in Brazil and the world. Approximately half of these deaths occur outside the hospital. OBJECTIVES: To analyze the distribution, temporal evolution, and sociodemographic characteristics (SDC) of in- and out-of-hospital deaths by AMI in Brazilian state capitals and their relationship with municipal development indicators (MDI). METHODS: This is an ecological study of the number of deaths due to AMI reported annually by the 27 Brazilian state capitals from 2007 to 2016; these were divided into 2 groups: in-hospital (H) and out-of-hospital (OH). We evaluated the temporal evolution of mortality rates in each group and differences in SDC. Negative binomial regression models were used to compare the temporal evolution of the number of deaths in each group with the following variables: residing in the South/Southeast regions (S/SE), municipal human development index (MHDI), Gini coefficient, and expected years of schooling (EYS). We considered p-values<0.05 as statisticallysignificant. RESULTS: The OH mortality rate increased with time for all state capitals. All studied SDC were different between groups (p<0.001). In the OH group, most deaths were of men and patients aged 80 years or older and not married. S/SE increased the incidence of OH deaths (incidence rate ratio [IRR]=2.84; 95% confidence interval [CI]=1.67-4.85), while higher EYS reduced it (IRR=0.86; 95% CI=0.77-0.97). In the H group, higher MHDI reduced the incidence of deaths (IRR=0.44; 95% CI=0.33-0.58), while higher EYS increased it (IRR=1.09; 95% CI=1.03-1.15). CONCLUSIONS: In- and out-of-hospital deaths due to AMI in Brazilian state capitals were influenced by MDI, presented sociodemographic differences and a progressive increase in out-of-hospital occurrences.


FUNDAMENTO: O infarto agudo do miocárdio (IAM) é a principal causa de óbito no Brasil e no mundo. Aproximadamente metade dos óbitos ocorrem fora do ambiente hospitalar. OBJETIVOS: Analisar a distribuição, a evolução temporal e as características sociodemográficas (CSD) dos óbitos intra e extra-hospitalares por IAM nas capitais brasileiras e a sua relação com indicadores municipais de desenvolvimento (IMD). MÉTODOS: Estudo ecológico com contagem anual dos óbitos por IAM nas 27 capitais brasileiras de 2007 a 2016, os quais foram divididos em dois grupos, intra-hospitalar (H) e extra-hospitalar (EH). Avaliou-se a evolução temporal das taxas de mortalidade em cada grupo e as diferenças das CSD. Modelos de regressão binominal negativa compararam temporalmente a contagem de óbitos em cada grupo com as seguintes variáveis: residir nas regiões Sul e Sudeste (S/SE), índice de desenvolvimento humano municipal (IDHM), índice de Gini e expectativa de anos de estudo (EAE). Considerou-se estatisticamente valores significativos de p < 0,05. RESULTADOS: A taxa de mortalidade EH para o conjunto das capitais aumentou ao longo do tempo. Todas as CSD pesquisadas foram difententes entre os grupos (p < 0,001). No grupo EH prevaleceram os óbitos em homens, em pacientes ≥ 80 anos e em solteiros. O S/SE elevou a incidência de óbitos extra-hospitalares (IRR = 2,84; IC 95% = 1,67-4,85), enquanto o maior EAE registrou queda (IRR = 0,86; IC 95% = 0,77-0,97). Para o grupo H, o maior IDHM reduziu a incidência de óbitos (IRR = 0,44; IC 95% = 0,33-0,58), enquanto o maior EAE apresentou crescimento (IRR = 1,09; IC 95% = 1,03-1,15). CONCLUSÃO: Os óbitos intra e extra-hospitalares por IAM nas capitais apresentam diferenças sociodemográficas, incidência influenciada por IMD e progressivo aumento da ocorrência extra-hospitalar.

RESUMO

The aim of this study was to analyze the association between birth by cesarean section and central adiposity in adolescents in São Luís, Maranhão State, Brazil. This was a cohort study that included 601 participants evaluated at birth and at 18-19 years. At birth we assessed type of delivery, maternal education, family income, maternal marital status, maternal body mass index before pregnancy, prenatal care, maternal smoking habit, gestational age at delivery and intrauterine growth restriction. In the adolescents, we evaluated central adiposity using the dual X-ray energy absorptiometry method. The indicators of central fat used were the trunk-to-total fat mass ratio (T/T), the android-to-gynoid fat mass ratio (A/G), the trunk-to-limb fat mass ratio (T/Lb), and the trunk-to-leg fat mass ratio (T/Lg). A theoretical model for the study of associations was developed using directed acyclic graphs, which allowed selecting the variables that required minimum adjustment for inclusion in the predictive model of exposure to cesarean delivery. The data were analyzed with marginal structural models weighted by the inverse of the probability of selection. A total of 38.6% of the adolescents studied were delivered by cesarean section. There was no significant difference in the central adiposity of adolescents delivered by cesarean section according to the indicators used: T/T ( coefficient = -0.003; 95%CI: -0.013; 0.007), A/G (coefficient = 0.001; 95%CI: -0.015; 0.018); T/Lb (coefficient = -0.016; 95%CI: -0.048; 0.016); T/Lg (coefficient = 0.014; 95%CI: -0.060; 0.030). In conclusion, there was no association between cesarean section delivery and greater central adiposity in the studied adolescents.
