Values are β (95% CI) derived from multiple linear regressions and expressed for per 1% energy substitution of a macronutrient for another macronutrient in the substitution model and per 1 g increase in absolute macronutrient intake in the addition model.
Model 1 was adjusted for age at MRI measurement.
Model 2 was further adjusted for ethnicity, maternal age, height, pre-pregnancy BMI, pregnancy weight gain until 26-28 weeks gestation, education status, gestational diabetes mellitus, infant gender, gestational age, and birth order.
