摘要

lass="h4">Objective

To explore the impact of the new Special Supplemental Nutrition Program for Women, Infants and Children (WIC) food package on WIC participant consumption of fruit, vegetables, whole-grain food, and lower-fat milk.

lass="h4">Design

Telephone surveys of cross-sectional samples of California WIC families before and after the changes to the food package.

lass="h4">Participants

Random samples of pregnant or postpartum women and/or caregivers of children enrolled in WIC: 3,004 in September, 2009; 2,996 in March,聽2010.

lass="h4">Main Outcome Measures

Consumption of fruit, vegetables, whole-grain food, and lower-fat milk.

lass="h4">Analysis

Comparisons of outcome variables were made by examining the differences by time point, adjusted for sociodemographic variables, using ANOVA (for means) or logistic regression (for percentages).

lass="h4">Results

Following the changes to the WIC food package, consumption of whole-grain food increased by 17.3 percentage points, a 51%increase over baseline. Caregivers and children who usually consumed whole milk decreased by 15.7 and 19.7 percentage points, respectively, a 60%-63%reduction over baseline. Accompanying increases in lower-fat milk consumption were demonstrated. Small but significant increases in consumption of fruits and vegetables were also observed.

lass="h4">Conclusions and Implications

Federal policy changes to the WIC program had the intended effect of increasing consumption of the prescribed food items.
