Objective: To develop the DQI-W, a modified version of an existing diet quality index, to assess diet quality among low-income pregnant women and to compare diet quality of American Indians (AI) and whites. Participants: North Dakota pregnant women enrolled in WIC, a special supplemental program for women, infants and children N=7,627). AI comprised 13.5% of the population. Design: Dietary intake was assessed using a semi-quantitative food frequency questionnaire, and DQI-W scores were derived for all participants based on 10 individual components: % recommended servings of grains, vegetables, fruits, % recommended intake of folate, calcium, and iron, % energy from fat, and saturated fat, %cholesterol intake, and a diet diversity score. Each component contributed 10 points to the total score, giving the DQI-W a maximum score of 100. Results: The mean DQI-W score was 53.5±12.9. Energy from total fat was higher than recommended, whereas servings of vegetables and grain and intakes of iron, and folate were below recommended values. AI had significantly lower DQI-W scores as compared to whites (51.6 for AI versus 53.6 for whites, p <0.0001). Cholesterol, total fat intake, and saturated fat intake were significantly higher among AI. However, AI consumed significantly higher amounts of iron and folate. Conclusion: The DQI-W scores indicate that this population is not meeting dietary recommendations through food intake alone and that there are significant differences in diet quality between AI and white pregnant women. Interventions should focus on decreasing fat intake and increasing iron and folate intake to meet national dietary recommendations.
