Objective: To examine the association between prepregnancy body mass index (BMI=kg/m2) and diet quality during pregnancy. Methods: From 1995 to 2000, 3,163 women were enrolled in the Pregnancy, Infection and Nutrition study in central North Carolina. 2,036 completed a food frequency questionnaire used to compile a Diet Quality Index for Pregnancy (DQI-P), and had data on weight, height, and socio-demographics. DQI-P is based on national recommendations for pregnancy and includes: servings of grains, vegetables, fruits, folate, iron and calcium intake, percent calories from fat, and meal patterning for a maximum score of 80. BMI was categorized as underweight (<18.5), normal (18.6-24.9), overweight (25-29.9), and obese (>30). Multinomial logistic regression was used with DQI-P categorized into tertiles as the outcome, controlling for maternal age, parity, education, marital status, poverty and race. Results: Prevalence of underweight, normal, overweight, and obesity was 6%, 53%, 20%, and 6%, respectively. The average DQI-P score was 54.2 points; by BMI category it was: 56 underweight, 54.8 normal, 53.9 overweight, and 52.9 obese. After controlling for confounding, obese women had a 35% increased risk of falling into the lowest compared to highest DQI-P tertile, [adjusted OR= 1.35 (95% CI 1.01, 1.80)] using normal weight women as the referent group. Risk of poor diet quality was similar among underweight [adjusted OR=0.85 (95% CI 0.54, 1.35)] and overweight women [adjusted OR=1.16 (95% CI 0.86, 1.56)] compared to normal weight women. Conclusion: Dietary intake of obese pregnant women should be targeted for improvement if they are to meet national recommendations.
