a

Models adjusted for BMI, work, physical activity, and weight gain attitudes. Estimated values are for women who delivered at term, were working during the second trimester, had mean levels of recreational physical activity, and mean levels of weight gain attitudes.

b

p-values test the effect of restrained eating, dieting, or weight cycling on total weight gain within each category of BMI

c

Models adjusted for BMI, maternal age, maternal race, and poverty. Estimated values are for white women age 29 (mean age) who delivered at term and were in the middle income category.

d

Models adjusted for BMI, work, physical activity, weight gain attitudes, maternal education, maternal race, and poverty. Estimated values are for white women who delivered at term, were working during the second trimester, had mean levels of recreational physical activity, mean levels of weight gain attitudes, some college education, and were in the middle income category. Estimated values shown are for underweight women, however there was no effect modification by BMI.
