Temporal trend of early neonatal mortality among children of adolescent mothers in Brazil and regions between 2000 and 2020

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Objectives: to analyze the temporal trend in early neonatal mortality among adolescent mothers in Brazil and macroregions between 2000 and 2020.

Methods: a mixed ecological study, using secondary data publicly available from the Live Birth Information System and the Mortality Information System, from which information was consulted on children born in Brazil, according to macro-region, between 2000 and 2020, descendants of adolescents. Infant mortality rates were calculated for Brazil and its macroregions for each year analyzed. Temporal analysis was performed using the Joinpoint Regression Model.

Results: we observed 101,508 early neonatal deaths. The Northeast region had the highest number of early neonatal deaths (37,919). The temporal trend between 2000 and 2020 in the early neonatal mortality rate among children of adolescent mothers in Brazil showed a decreasing pattern, presenting an average variation for the period (AAPC, Average Annual Percent Change) of -0.90; p<0.001. The greatest decrease was observed in the Southern (AAPC = -2.23; p<0.001) and the lowest in the North, with a general stationary temporal trend (APC = -2.64; p<0.001).

Conclusion: the findings showed a decreasing temporal trend in the early neonatal mortality rate among children of adolescent mothers from 2000 to 2020 in Brazil. The greatest reduction was observed in the South, while the North presented a general stationary temporal trend.
