Abstract

Objective: This study assessed maternal mortality (MM) and related factors in a large-sized municipality in the Southeastern region of Brazil (Campinas, São Paulo) during the period 2000-2015.

Methods: This study consisted of two phases: 1. An analytical nested case-control phase that assessed the impact of individual and contextual variables on MM; and 2. an ecological phase designed to contextualize maternal deaths by means of spatial analysis. The case group consisted of all maternal deaths (n = 87) and the control group consisted of 348 women who gave birth during the same period. Data analysis included descriptive statistics, association, and multiple logistic regression (MLR) tests at p < 0.05 as well as spatial analysis.

Results: Maternal Mortality Ratio was 37 deaths per 100.000 live births. Deaths were dispersed throughout the urban territory and no formation of cluster was observed. MLR showed that pregnant women aged ≥ 35 years old (OR = 2.63) or those with cesarean delivery (OR = 2.51) were more prone to maternal death.

Conclusion: Maternal deaths were distributed dispersedly among the different socioeconomic levels and more prone to occur among older women or those undergoing cesarean deliveries.

Resumo

Objetivo: Esse estudo avaliou a mortalidade materna (MM) e fatores relacionados em um município de grande porte da região sudeste do Brasil (Campinas, São Paulo) no período de 2000-2015.

Métodos: Esse estudo consistiu de duas fases: 1. Uma fase analítica de caso-controle que avaliou o impacto de variáveis individuais e contextuais na MM; 2. Uma fase ecológica delineada para contextualizar as mortes maternas por meio de análise espacial. O grupo caso consistiu de 87 mortes maternas e o grupo controle de 348 mulheres que tiveram bebês durante o mesmo período. Os dados foram analisados por estatística descritiva, testes de associação e regressão logística múltipla (RLM) (p < 0,05) assim como análise espacial.

Resultados: A taxa de mortalidade materna foi de 37 mortes para cada 100.000 nascidos vivos. As mortes foram dispersas por todo o território urbano e não se observou formação de clusters. Na RLM observou-se que mulheres grávidas com idade ≥ 35 anos (OR = 2,63) ou aquelas que passaram por cesárea (OR = 2,51) foram mais propensas à morte materna.

Conclusão: As mortes maternas foram distribuídas dispersamente entre os diferentes níveis socioeconômicos e mais propensas a ocorrer entre mulheres ≥ 35 anos de idade ou que passaram por cesárea.
