Note. NHANES = National Health and Nutrition Examination Survey; MET = metabolic equivalent scores; sample weight to conduct all the analyses; data are presented as mean ± SE or otherwise specified; the other values for continuous variable were obtained by performing SURVEYREG, and values for category variables were obtained by performing SURVEYLOGISTIC to perform the adjusted analyses, adjusted for age, race, parental education level, and family income to poverty ratio; ^$accumulated ≥1680 MET-minutes/week for 12–17 years old, and accumulated ≥600 MET-minutes/week for 18–19 years old; ^#data were only available for participants aged 12–15 years; ^anormal differs from overweight (); ^bthin differs from overweight (); ^cthin differs from normal weight ().
