HEI, Healthy Eating Index-2015. ¹ Linear regression was performed with FIML, full information likelihood ratio. n = 303 in pregnancy and n = 206 in postpartum. Adjusted model was adjusted for income, race, education, proportion of recalls on weekend, mean weekly frequency of moderate/vigorous physical activity, highest value reported for eating less due to nausea (pregnancy models only), and breastfeeding duration (postpartum models only). * α < 0.05 indicates statistical significance.
