Home food availability, parents’/caregivers’ support, and family meals influence on dietary servings of low-income urban adolescent girls from Brazil

Background: There is a striking lack of evidence about parents’/caregivers’ influence on their children’s dietary intake across Brazil and other middleand low-income countries. Therefore, the purpose of this study was to identify the associations between adolescents’ dietary intake and home environment, family meals and parental support. Methods: Cross-sectional study with 14–18 years old adolescent girls was conducted in 10 public schools in the city of São Paulo. Girls’ dietary intake, home food environment, parental support, and family meals’ frequency were selfreported by 253 adolescents. Brazilian Food Pyramid recommendation was used as reference for the dietary intake. Linear regressions were used to verify the associations between home environmental, parental support, and family meal frequency with dietary intake. Results: Girls parents’ support for healthy eating was positively associated with the fruits group (mean (95%CI) 0.75 (0.66 to 0.84) ß = 0.26, p = 0.003), and the vegetables group (3.40 (3.08 to 3.72, ß = 0.25, p = 0.006) and negatively associated with the meat and eggs group (2.09 (1.93 to 2.25), ß = −0.14, p = 0.041). Home environment was associated with fruits group (0.73 (0.63 to 0.82), ß = 0.35, p = 0.001). The associations between sharing family meals and food groups were not statistically significant. However, girls demonstrated a positive association with dietary intake and sharing family meals. Conclusion: Parental support and home food environment were associated with dietary intake of the adolescent girls. Future studies—mainly from lowand middle-income countries —are needed to provide additional evidence on these associations and the effects of youth home environment.
