β (95% CI) values are given in relation to each continuous factor score; ORs (95% CI) of being in Q4 vs Q1–3 for each factor are shown
n = 15 participants excluded from the analyses due to missing values for covariates
n = 159 participants excluded from the analyses due to missing values for covariates
Percent variance accounted for by each factor with respect to the original metabolite dataset
Model 1: Adjusted for child’s age, sex and race/ethnicity
Model 2: Model 1 + mother’s smoking habits during pregnancy
Model 3: Model 2 + Tanner stage (based on pubic hair development in boys and breast development in girls), physical activity levels (mean METs/day over a 3-day period), and total energy intake (kJ/day)
Model 4: Model 3 + GDM treatment (diet and/or exercise only, diet and/or exercise with insulin or insulin only, or no treatment)
Model 5: Model 2 + pre-pregnancy BMI (kg/m2)
