In linear regression models described here, the primary exposure was total reported carbohydrate intake in the 24 hours (ASA24, SPRING) and 6 weeks (FFQ, BABI) preceding the OGTT (grams). The coefficient for outcome, 120-minute postload glucose, is given per 50-g increase in carbohydrate intake.
Unadjusted model: no adjustments. Caloric intake model: adjustment for total caloric intake (kcal/24 hours). Adjusted model: adjustment for age, BMI, time postpartum, race/ethnicity, education, total caloric intake (kcal/24 hours).
