OR: odds ratio; 95%CI: 95% confidence interval; ap<0.05, adjusted for all covariates; banalysis according to other covariates, keeping those with p≤0.20. For the association between excess weight and other covariates, the final model comprising the variables gender and age group showed a pseudo R2=0.1292, Akaike information criterion (AIC)=674.48, and Bayesian information criterion (BIC)=691.95. Compared to the saturated (pseudo R2=0.1344, AIC=680.52, and BIC=719.84) and null (pseudo R2=0, AIC=767.40, and BIC=771.77) models, the final model had a value of 0.55 and <0.001, respectively, according to the likelihood ratio test. For the association between abdominal obesity and other covariates, the final model comprising the variables gender, maternal schooling, alcohol consumption, cigarette smoking, and screen time-based sedentary behavior showed a pseudo R2=0.0297, AIC=418.77, and BIC=444.95. Compared to the saturated (pseudo R2=0.0350, AIC=422.52, and BIC=461.79) and null (pseudo R2=0, AIC=421.21, and BIC=425.57) models, the final model had a value of 0.52 and 0.03, respectively, according to the likelihood ratio test.
