-Overall N = 422, 101 overweight young adults (BMI≥25 kg/m2).- OR (95% CI) represents estimate for ≥85th percentile by target age compared to th percentile by target age (OR = 1.00).- aNovwt/ N85th = Number who became overweight as young adults in the group who were ≥85th% at the target age.- Model 1: 1OR (95% CI) = Adjusted for sex, gestational age at birth, age at adulthood obesity assessment, birth year,- Model 2: 2OR (95% CI) = Model 1 further adjusted for birth WHO weight-for-age or weight-for-length Z-score.- Model 3: 3OR (95% CI) = Model 2 plus maternal and paternal age and BMI.
