This study investigated the relationship between regional distribution of childhood obesity in Italy, family environment, and adolescent's dietary habits, physical activity, nutritional knowledge, and obesity. The findings showed that parental BMI had a direct influence on adolescent's BMI, independent of parental nutritional knowledge and habits. It was also found that parents transmitted eating and physical activity habits to their children. The study concluded that family-based approaches should be considered in the prevention of childhood obesity.
There are marked differences in the regional distribution of childhood obesity in Italy. This study sought to investigate the interaction between geographical areas and family environment of dietary habits, physical activity, nutritional knowledge and obesity of adolescents. A cross-sectional study was conducted on 426 school-aged children and 298 parents residing in Central Italy (Florence, Tuscany) and Southern Italy (Corigliano, Calabria), in 2021. Survey questionnaire investigated anthropometry, eating behavior, nutritional knowledge and physical activity. BMI was determined and compared with reference percentile charts for adolescents. Multivariate regression analyses showed that: (1) an adolescent's BMI was directly influenced by their parents' BMI independently of parental nutritional knowledge and dietary or physical activity habits; (2) parents transmitted eating or physical activity habits to their children; (3) the geographic region of residence is not in itself an independent determinant of children's BMI. The clear message is that prevention of childhood obesity should consider family-based approaches. Parental obesity can be the point of convergence of the complex interactions between a parent's and child's habits and should be one of the most important factors to look for.
