Exposure to communities of higher obesity prevalence may be shifting the publicâs perception of ideal weight to heavier weights.

We conducted a cross-sectional study using the Youth Risk Behavior Survey 2011. A total of 11,972 adolescents were included for analysis. All variables were self-reported. Data were stratified by sex and analyzed using multivariate logistic regression models adjusted for confounders and accounting for sampling weights. BMI was included as an interaction term in all models. Results. High obesity prevalence was associa
