The study analyzed the temporal tendency of stunting prevalence among children under five years of age in the Brazilian Northern Region from 2008 to 2017. It found a reduction in stunting prevalence in the Northern Region, particularly in three states. The study also revealed a negative correlation between SISVAN coverage and stunting prevalence in four states.
Objective: To analyze the temporal tendency of stunting prevalence among children under five years of age registered in the Food and Nutritional Surveillance System (SISVAN) in the Brazilian Northern Region, from 2008 to 2017. Methods: Ecological time-series study with data from SISVAN. The annual variation rate for the prevalence of undernutrition, measured by the presence of stunting (low height-for-age index), was estimated for the Northern Region and for each of its states using the Prais-Winsten regression model with and without variable adjustment for SISVAN coverage to explore the relationship between these variables. Results: The Northern Region showed a tendency toward the reduction of chronic child stunting, with an annual variation of -5.30% (95%CI -9.64; -0.77) in the period studied. The states of Acre (-7.19%; 95%CI -12.31; -1.77), Para (-4.86%; 95%CI -9.44; -0.03), and Tocantins (-6.22%; 95%CI -9.88; -2.41) showed a tendency to reduce the prevalence of stunting, while the other four states showed stability during the period. A strong negative correlation was found between SISVAN coverage and the prevalence of stunting in the states of Acre (beta: -0.725), Amazonas (beta: -0.874), Para (beta: -0.841), and Tocantins (beta: -0.871), indicating that the increase in system coverage is associated with a reduction of stunting. Conclusions: There is a tendency toward a reduction in the prevalence of stunting particularly in three states and in the North Region as a whole, from 2008 to 2017. The coverage by the system was associated with a reduction in the prevalence of child stunting in four states. (c) 2022 Sociedade Brasileira de Pediatria.
