BMI—body mass index, zBMI—body mass index z score.
↵* Being overweight is defined as zBMI > 1 to ≤ 2; being obese is defined as zBMI > 2 using World Health Organization growth standards.
↵† A 2 × 2
2 test comparing prevalence of both being overweight (yes or no) and being obese (yes or no) by age group. Each age group was compared to the adjacent older age category (< 1 y to 1–4 y, 1–4 y to 5–9 y, 5–9 y to 10–14 y, and 10–14 y to 15–19 y).↵‡ P < .001.
↵§ P < .05.
↵‖ A 2 × 2
2 test comparing prevalence of both being overweight (yes or no) and being obese (yes or no) versus sex (female or male) within each age group. Male is the referent.↵¶ P < .01.
