Odds ratio and 95% confidence interval of being overweight (BMI≥25 kg/m²) as a young-adult (age 20–29 years) according to percentile of the WHO infant growth standards: Infants ≥85^th percentile vs. <85^th percentile.

-Overall N = 422, 101 overweight young adults (BMI≥25 kg/m²).

- OR (95% CI) represents estimate for ≥85^th percentile by target age compared to <85^th percentile by target age (OR = 1.00).

- ^aN^ovwt/ N^85th =  Number who became overweight as young adults in the group who were ≥85^th% 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.
