OR, odds ratios; CI, confidence intervals; MVPA, moderate-vigorous PA. * International Obesity Task Force body mass index cut-off values. † Waist circumference cut-off values for predicting risk factor clustering, as proposed by Bogalusa Heart Study. ‡ Logistic regression analysis was performed controlling for sex and age. ** Low, middle and high PA levels represent the 1^st, 2^nd and 3^rd tertiles, respectively. They all were age- and sex-specifically calculated. †† Since the number of children not meeting PA recommendations were very small (≤ 1%), this analysis was performed only for adolescents.
