Abstract
To analyze the temporal trend of Food and Nutrition Surveillance System (SISVAN) coverage and nutritional status of adults undergoing follow-up in the Brazilian Primary Health Care, 2008-2019. This was an ecological time series study using data on Brazilian macro-regions. The annual percent change in the classification of nutritional status and total coverage was estimated using the Prais-Winsten regression model. A total of 115,034,534 records were identified in the period. Coverage increased from 5.0% in 2008 to 10.6% in 2019, with an annual change of 8.4%, 95% confidence interval (95%CI 6.7;10.0). Obesity and overweight showed a rising trend between 2008 and 2019, with an annual change of 6.4% (95%CI 5.3;7.3) and (1.8%; 95%CI 1.2;2.5) respectively, while underweight (-7.0%; 95%CI -8.0;-6.1) and eutrophy (-3.8%; 95%CI -4.1;-3.4) decreased in the period. There was an improvement in SISVAN coverage, with an increase in overweight and obesity among the population studied.
