  • ORs of the HBW group for overweight and obesity were assessed by multivariate logistic regression with the dependent variable (overweight or obesity) and independent variable (birth weight).

  • *P<0.05.

  • †Model 1 was unadjusted for any covariates.

  • ‡Adjusted for urban–rural area, single child, delivery, fruit and vegetable intake, sugar-sweetened beverage, moderate and vigorous physical activity, sedentary time, and elevated blood pressure.

  • §Further adjusted for paternal and maternal education level, hypertension, diabetes and obesity.

  • AOR, adjusted OR; HBW, high birth weight; NBW, normal birth weight.
