Abstract:

This study aimed to analyze the trends2008 to 2018 of overweight (OW) prevalence among under-five-year-old children assisted by the Programa Bolsa Familia (PBF; Bolsa Família Programme, in English). The panel was based on the nutritional status reports of the Food and Nutritional Surveillance System (SISVAN) (n=30,574,118). Age- (infants and preschoolers) and region-specific joinpoint regression models were used to analyze OW’s prevalence temporal changes. Besides, the coverage of SISVAN for PBF and national representativity were calculated according to census projection. In the decade analyzed, OW in infants decreased11.9% (11.8; 12.0 95%CI) to 8.5% (8.4; 8.6 95%CI) (-3.6%/year [-5.1; -2.0 95%CI]); for preschool children, the prevalence of OW increased by 3.1%/year (2.0; 4.2 95%CI) until 2015, followed by a decrease until 2018 (-6.4%/year [-10.1; -2.6 95%CI]). In both age groups, the North region had the lowest prevalence in all time-series, and the Northeast had the worst performance in controlling childhood obesity. The SISVAN\'s coverage in the PBF was high, and the data representativity varied between 13.9% (South) and 42.2% (Northeast). Although the prevalence was higher than expected, after 2014, it was detected a linear reduction in EP in infants and a deceleration in the growth rate in preschoolers.
