Background Prepregnancy overweight and obesity are determinants of excessive gestational weight gain and thus pregnancy complications and poor health outcomes. The association of prepregnancy weight status with diet quality during pregnancy remains unclear. Objective We aimed to investigate the relation between prepregnancy weight status and diet quality during pregnancy. Methods The study was based on 795 U.S. pregnant women in National Health and Nutrition Examination Survey (NHANES) 2003–2012. Prepregnancy weight status was classified by <18.5 (underweight), 18.5–24.9 (normal), 25.0–29.9 (overweight), and ≥30 kg/m 2 (obese). Diet quality during pregnancy was assessed by the Healthy Eating Index (HEI)‐2010 based on a 24‐hour recall. Multiple logistic regressions were used to estimate the adjusted odds ratios (AOR) and 95% confidence intervals (CI) for the association between prepregnancy BMI and diet quality during pregnancy assessed by the HEI‐2010 after controlling for maternal sociodemographic characteristics and physical activity during pregnancy. Results For all pregnant women in this study, the mean HEI‐2010 was 50.7 (± 0.9). Women with obese prepregnancy BMI had significantly lower HEI‐2010 compared to underweight and normal prepregnancy BMI groups, respectively (45.8 ± 1.6 vs. 52.4 ± 1.7, 52.3 ± 1.6). In an unadjusted model, women with prepregnancy obesity BMI had increased odds for being in the lowest tertile of HEI‐2010 compared to those with normal prepregnancy BMI (OR 4.99; 95% CI 2.19–11.37). The inverse association between prepregnancy obesity status and diet quality persisted even after controlling for physical activity levels (AOR 5.50; 95% CI 2.05–14.77). Conclusion Prepregnancy weight status was inversely associated with diet quality during pregnancy. Our findings suggest that women with overweight and obese prepregnancy BMI need to be targeted for nutritional interventions during pregnancy.
