Maternal mortality in adolescents and young adults: temporal trend and correlation with prenatal care coverage in the state of Bahia, Brazil, 2000-2020.

MAIN RESULTS: From 2000 to 2020, maternal mortality among adolescents and young adults showed a decreasing trend in the state of Bahia. It could be seen an inverse and significant correlation between the highest number of prenatal care visits and maternal mortality in the studied groups. IMPLICATIONS FOR SERVICES: The study suggests the importance of quality obstetric care during prenatal, childbirth, and postpartum period for reducing maternal mortality among adolescents and young adults, especially from preventable causes. PERSPECTIVES: Improving the records of causes of death on information systems, enhancing obstetric care, and investing in sexual and reproductive health policies aimed at adolescents may contribute to the reduction of maternal deaths. OBJECTIVE: to analyze the temporal trend of maternal mortality and correlate it with prenatal care coverage among adolescents and young adults, state of Bahia, Brazil, 2000-2020. METHODS: this was an ecological time-series study and correlation between maternal deaths and prenatal care visits in 10-19 and 20-24 age groups, using the Mortality Information System; the trend analysis was performed by means of Prais-Winsten regression, according to race/skin color, timing and causes of death; and Spearman coefficient was used for correlation. RESULTS: in the study period, 418 deaths among adolescents and 574 among young adults were recorded; maternal mortality ratio was 59.7 and 63.2 deaths/100,000 live births, with a significant decreasing trend (-2.2% and -2.9% respectively); it could be seen an inverse correlation between a higher number of prenatal care visits and maternal mortality in the age groups. CONCLUSION: maternal mortality showed a decreasing trend in the study period, but with high proportions of death; there was a significant correlation between prenatal care coverage and maternal mortality among adolescents and young adults.

Objetivo: analisar a tendência temporal da mortalidade materna e correlacioná-la com a cobertura pré-natal entre adolescentes e adultas jovens, Bahia, Brasil, 2000-2020. Métodos: estudo ecológico de série temporal e correlação entre óbitos maternos e consulta de pré-natal aos 10-19 e 20-24 anos, utilizando-se o Sistema de Informações sobre Mortalidade; a tendência foi analisada pela regressão de Prais-Winsten, segundo raça/cor da pele, causas e momento do óbito; para a correlação, utilizou-se o coeficiente de Spearman. Resultados: no período, foram registrados 418 óbitos de adolescentes e 574 de adultas jovens; razão de mortalidade materna de 59,7 e 63,2 óbitos/100 mil nascidos vivos, com tendência decrescente significante (-2,2% e -2,9% respectivamente); observou-se correlação inversa entre maior número de consultas e mortalidade materna, nos grupos etários. Conclusão: a mortalidade materna apresentou tendência de redução no período, porém com altas proporções de óbito; houve correlação significante entre cobertura pré-natal e mortalidade materna, entre adolescentes e adultas jovens.

Objetivo: analizar la tendencia temporal de la mortalidad materna y correlacionarla con la cobertura prenatal, entre adolescentes y adultas jóvenes, en el estado de Bahía, período 2000-2020. Métodos: estudio ecológico de series temporales y correlación entre muertes maternas y atención prenatal, en grupos de edad de 10-19 y 20-24, utilizando el Sistema de Información de Mortalidad.

Resultados: en el período se registraron 418 muertes de adolescentes y 574 de adultas jóvenes; razón de mortalidad materna de 59,7 y 63,2 muertes/100.000 nacidos vivos, con importante tendencia a la baja (-2,2%; -2,9%, respectivamente). Se observó correlación inversa entre el mayor número de consultas y la mortalidad materna en grupos. Conclusión: la mortalidad materna mostró tendencia descendente en el período, pero con altas proporciones de muertes. Hubo una correlación significativa entre la cobertura prenatal y la mortalidad materna, adolescente y adulta joven.
