Race and SES were self-reported prenatally; SES was categorized into four groups: high-income, middle-income and low-income WIC (Special Supplemental Nutrition Program for Women, Infants, and Children) participant/non-participant. The Alternative Healthy Eating Index for Pregnancy (AHEI-P) measured diet quality, including four moderation and nine adequacy components (higher scores = healthier diet). Generalized linear models adjusted for covariates and<jats:italic>post hoc</jats:italic>testing with Tukey adjustment compared AHEI-P scores between groups, using a threshold of<jats:italic>P</jats:italic>< 0·05.</jats:p></jats:sec><jats:sec id="S1368980019003240_as3" sec-type="other"><jats:title>Setting:</jats:title><jats:p>Infant Feeding Practices Study II, conducted in a national US convenience cohort.</jats:p></jats:sec><jats:sec id="S1368980019003240_as4" sec-type="other"><jats:title>Participants:</jats:title><jats:p>Women in their third trimester (<jats:italic>n</jats:italic>1322) with dietary history.</jats:p></jats:sec><jats:sec id="S1368980019003240_as5" sec-type="other"><jats:title>Results:</jats:title><jats:p>Participants were of 28·9 (<jats:sc>se</jats:sc>5·6) years on average and predominantly non-Hispanic White (84 %); approximately one-third participated in WIC and 17 % were high-income. The mean AHEI-P score was 61·7 (<jats:sc>se</jats:sc>10·8) of 130 points. High-income women had higher total (62·4 (<jats:sc>se</jats:sc>1·0)) and moderation component AHEI-P scores than middle-income (60·1 (<jats:sc>se</jats:sc>0·8),<jats:italic>P</jats:italic>= 0·02), low-income WIC participants (58·3 (<jats:sc>se</jats:sc>0·8),<jats:italic>P</jats:italic>< 0·0001) and non-participants (58·9 (<jats:sc>se</jats:sc>0·9),<jats:italic>P</jats:italic>= 0·001). Non-Hispanic Black participants had lower total (57·8 (<jats:sc>se</jats:sc>1·4)) and adequacy scores than Other races (i.e. neither non-Hispanic Black nor White, 62·1 (<jats:sc>se</jats:sc>0·9),<jats:italic>P</jats:italic>= 0·02).</jats:p></jats:sec><jats:sec id="S1368980019003240_as6" sec-type="other"><jats:title>Conclusions:</jats:title><jats:p>Disparities in prenatal diet quality were observed, with non-Hispanic Black women, low-/middle-income and WIC participants having lower diet quality. However, interventions are needed to improve prenatal diet quality broadly among US women.</jats:p></jats:sec>
