* p < 0.05 within wave and sex; ** p < 0.01 within wave and sex

a Obesity defined as BMI ≥ 30 kg/m2 equivalent age- and sex-specific IOTF cut-points at Wave II; BMI ≥ 30 kg/m2 at Wave III.

b National Longitudinal Study of Adolescent Health [N = 9,155]. Weighted for national representation, standard errors corrected for survey design effects of multiple stage cluster sampling.

c Combined with "Current" in regression modeling for Wave II

d Variable is not applicable for Wave II

e Insufficient cell size; combined with Summer for Wave II
