  1. aCross-sectional data from the Korea School Health Examination Survey (2011–2015, 1761 schools)
  2. bOutcome variables: Body mass index (BMI)
  3. c P-value of Wald’s test; β, coefficient of regression parameters; SEM, standard error of the mean; R 2, coefficient of determination
  4. dAll variables in the left column of the table are explanatory variables, and their associations (including place of residence, 17 cities and provinces in South Korea) with BMI were simultaneously adjusted using multiple linear regression
  5. eReference group: Aged 9 y = 0; Urban areas = 0; Dietary patterns, food intake > 5 servings/wk = 0; Exercise ≥ 5/wk = 0; Internet or games < 2 hr/d = 0
