RESUMEN
BACKGROUND: The aim of this study was to evaluate the association between urbanization of residential area, parent education level, employment status, overweight/obesity, physical activity, and exposure to environmental tobacco smoke (ETS), in a sample of healthy Italian school-age children (5-11 years). METHODS: A cross-sectional study was conducted on 432 children resident, respectively, in a highly urban and in a rural area (Latium Region) in 2014. Information on children and families were obtained via questionnaire. RESULTS: One-third of children were overweight or obese, 15% did not participate in any sport outside school, and more than one-third were exposed to ETS in the domestic environment. Living in a rural area (adjusted OR, 2.55; 95%CI: 1.18-5.52) and lower maternal education (adjusted OR, 2.32; 95%CI: 1.03-5.27) were significant predictors of overweight/obese status. Moreover, lower maternal education level (adjusted OR, 2.74; 95%CI: 1.40-5.33) and paternal education level (adjusted OR, 3.06; 95%CI: 1.54-6.07) were significant predictors of ETS exposure. CONCLUSIONS: It is essential to investigate the reasons underlying the higher frequency of overweight/obesity in children living in rural environments compared with those in urban areas; and preventative actions should be designed to be easily understood by those with lower education levels.
