EXTERNAL CAUSE MORTALITY IN CHILDREN UNDER FIVE IN BRAZIL: A TIME SERIES STUDY FROM 2000 TO 2020
Child Health. Epidemiology. Child mortality. External causes.
Important progress has been made in reducing infant and early childhood mortality. However, deaths from external causes are preventable and have a major impact, making them an important public health problem worldwide. This study aims to assess mortality from external causes in children under five in a historical series from 2000 to 2020 in Brazil. This is an ecological study using secondary data from the Mortality Information System, a DATASUS system, collected from 2000 to 2020 and analyzed using Joinpoint software to obtain linear regression to correct the rates from junction points in the time series and temporal analysis of the variables. Geoda was used for the spatial analysis. The results showed that the most prevalent chapters were, respectively: Chapter XVI - certain conditions originating in the perinatal period; Chapter XVII - congenital malformations, deformities and chromosomal anomalies; Chapter I - certain infections and parasitic diseases; Chapter X - diseases of the respiratory system and Chapter XX - external causes of morbidity and mortality, the latter showing large variations in the rate each year and with an upward trend, followed by a downward trend in mortality. We also found a spatial distribution of infant mortality among Brazilian states, so that the Southeast, South and Northeast regions have higher incidences of deaths from external causes. We also evaluated the linear regression of the mortality rate based on the fragmentation into age groups, making it possible to assess the behavior of deaths in the age group between 1 and 4 years and under one year, showing a change in ranking depending on the age group. Thus, it can be concluded that the reduction of preventable deaths in the child population depends on the implementation of public policies for which society as a whole is responsible, as well as the need to develop public policies in order to enable the development of strategies based on epidemiological indicators.
