title: Characteristics of diet among a culturally diverse group of low-income pregnant women.
abstract: This study reports on diet quality and variety in food selection among a culturally diverse group of 335 low-income pregnant Massachusetts women. The Index for Nutritional Quality (INQ), which is the observed nutrient density divided by the recommended nutrient density, was estimated for seven nutrients from data reported on food frequency questionnaires and diet recalls. Mean INQs for protein and vitamin C were above the recommended level of 1.0, whereas INQ for iron was 0.6 or less. Mean INQ for calcium was 1.2 for whites and between 0.9 and 1.0 for non-whites. When comparisons were made among ethnic groups by site of prenatal care, significant differences in INQ were found for all nutrients except iron and vitamin B-6. WIC participants had higher diet quality for protein, calcium, iron, and vitamin B-6 than did non-participants. Employed women had higher protein and zinc INQs than did unemployed women, and non-smokers had higher iron and vitamin B-6 INQs than did smokers. Variety was not significantly correlated with diet quality but differed (p less than .001) among site-specific ethnic groups. We conclude that there is a need for investigation of factors influencing dietary practices that are associated with sites of prenatal care.
