Unadjusted and adjusted results of analyses examining relationships between wave IV weight category with metabolic health (Hypothesis 1 A) and change in BMI (Hypothesis 1B), among eligible participants in the add health study

Hypothesis 1 A: Association between wave IV weight category and wave V metabolic health (n = 788)
Wave IV weight category	Unadjusted risk difference (95% CI)	Adjusted risk difference (95% CI)
Normal weight	Ref	Ref
Overweight	0.17 (0.084, 0.25)	0.15 (0.066, 0.24)
Obesity	0.30 (0.22, 0.38)	0.32 (0.24, 0.40)

Hypothesis 1B: Association Between Wave IV Weight Category and change in BMI between Wave IV and Wave V (n = 901)
Wave IV Weight Category	Unadjusted β (95% CI)	Adjusted β (95% CI)
Normal weight	Ref	Ref
Overweight	0.48 (− 0.19, 1.15)	0.45 (− 0.18, 1.08)
Obesity	− 0.88 (− 1.64,− 0.11)	− 0.98 (− 1.75,− 0.20)

BMI body mass index, CI confidence interval

Bold indicates statistical significance at the α = 0.05 level

Logistic regression models were used to examine changes in metabolic health and linear models were used to examine changes in BMI. Models were adjusted for Wave IV age, race, sex, Wave IV educational attainment, and Wave IV smoking status
