MORTALITY AND HOSPITAL ADMISSIONS AMONG CHILDREN IN BRAZIL AND THE NORTHEAST MACROREGION: ECOLOGICAL TIME SERIES STUDY, 2000-2019
Mortality. Morbidity. Child Health. Hospitalization.
Child morbidity and mortality in Brazil have significantly decreased over the past decades. However, mortality rates remain high compared to countries with very high Human Development Index (HDI). Additionally, health challenges and social inequities remain evident across the country, requiring the implementation of effective public policies. This research aimed to investigate trends in mortality and hospital admission rates among children aged 0 to 14 years. The study is an ecological, time-series analysis using a quantitative approach, based on secondary data on infant mortality and hospital morbidity (<1 year), early childhood (<5 years), and children aged 5 to 14 years in Brazil and the Northeast Region from 2000 to 2019. Data were collected through the Department of Informatics of the Brazilian Unified Health System (DATASUS), and trend analysis was conducted using the Joinpoint statistical software.
The findings reveal a significant downward trend in infant and childhood mortality rates in Brazil and the Northeast. However, following an inflection point in 2014, mortality rates stabilized. For children aged 5 to 14 years, the decline was even more pronounced, beginning in 2013 nationwide and in 2012 in the Northeast. Hospital admission rates showed more fluctuations. Among children under 1 year, there was a significant decrease in hospital admissions, but after inflection points in 2014 (Brazil) and 2011 (Northeast), a sharp increase in hospitalizations was observed. A similar trend occurred for children under 5 years, with inflection points in 2015 (Brazil) and 2008 (Northeast). For children aged 5 to 14 years, the national trend showed the greatest reduction after 2010, while in the Northeast, the decline persisted until 2017, followed by an upward trend.
Over the two decades studied, significant progress was made in reducing child morbidity and mortality in both regions. However, improvements in social indicators and healthcare actions have been affected by austerity measures, posing challenges for Brazil in maintaining and advancing public health policies.
