Predictors of dietary milk fat intake by preschool children

High-fat whole milk is the major dietary source of total and saturated fat for young children. Children from low-income families have higher total and saturated fat intakes and their parents have higher rates of cardiovascular disease compared with children from higher income families. We identified factors that predict the use of either high-fat whole milk or low-fat (1% and/or skim) milk by children to facilitate the development of targeted intervention strategies to reduce their dietary fat intakes.

Adults (91% mothers) with children > or =1 through <5 years of age, participating in the Supplemental Nutrition Program for Women, Infants, and Children (WIC) at 50 agencies throughout New York State, completed questionnaires.

Most (75%) of the 1,938 children drank whole milk, while only 6.9% consumed exclusively 1% and/or skim milk. The children tended to drink the same type of milk as other family members. In multivariate logistic regression, use of whole milk was associated with younger child age, black race or Hispanic ethnicity, parent/guardian belief that whole milk was healthier for children over 2, and parent/guardian having never tried reduced-fat milks (all P < 0.0001). In contrast, use of 1% and/or skim milk was associated with older child age, female gender, nonblack race, older parent/guardian age, parent/guardian belief that reduced-fat milks were healthier for children over 2, and parent/guardian having tried 1%-fat milk (all P < 0.01).

Individualized family-based strategies are needed to target specific behaviors and/or health beliefs held by different parent groups. For example, taste testing might be an effective strategy for parents who have never tasted reduced-fat milk. Interventions to overcome cultural barriers to the use of low-fat milk may require changing parental health beliefs, in addition to providing education about the health benefits of low-fat milk.
