Social determinants of health associated with the experience of hunger among Brazilian adolescents.

The aim of this study was to identify social determinants of health associated with the experience of hunger among school-age adolescents in Brazil. We conducted a cross-sectional study with a sample of 16,526 adolescents using data from the 2015 National School-based Student Health Survey. Experience of hunger was determined based on the answer to the question "In the last 30 days, how often have you been hungry because there wasn't enough food at home?" The social determinants of health were analyzed using Poisson regression with robust variance. The prevalence of the experience of hunger was 22.8% (95%CI: 21.9-23.7). The experience of hunger was directly associated with being male (PR = 1.12; 95%CI: 1.07-1.16); not being overweight (PR = 1.08; 95%CI: 1.04-1.13 ); irregular consumption of beans (PR = 1.20; 95%CI: 1.13-1.26), vegetables (PR=1.16; 95%CI: 1.09-1.22) and fruit (PR = 1.19; 95%CI: 1.13-1.24); body dissatisfaction (PR = 1.26; 95%CI: 1.18-1.35); and not regularly eating lunch or dinner with parents or guardians (PR = 1.41; 95%CI: 1.32-1.52). An inverse association was found between the experience of hunger and maternal education level and living in the Mid-West, Southeast and South. The findings show that the experience of hunger among Brazilian adolescents coexists with risky eating behaviors, body dissatisfaction, and social inequality.
