The 2009 WIC revisions significantly increased purchases of whole-grain bread and rice among WIC-participating families.
Eighteen months following the WIC food package revisions, significant decreases in total fat and saturated fat and increases in dietary fiber and overall diet quality were observed among Hispanic children only. No significant changes in nutrient intake or diet quality were observed for any other group.
This research suggests that recent policy change to the WIC food package improves WIC participant access to healthful food options without decreasing satisfaction
Compared to their African American counterparts, diets of Hispanic mothers and children were lower in percentage of calories from fat, added sugars, sodium, and sweetened beverages, but higher in vitamin A, calcium, whole grains, fruit, and total dairy. However, no groups met national recommendations for percentage of calories from saturated fat, fiber, sodium, whole grains, vegetables, and total dairy.
Results suggest the WIC policy revision contributed to modest reductions in F/V prices. WIC participants’ purchasing power can differ depending on the type and neighborhood of the WIC vendor used.
After four weeks, the mothers reported increased child's consumption of low-fat milk vs. whole milk. Mothers' consumption of low-fat milk did not significantly change after introduction of the new package.
The availability of healthful food increased significantly in stores, overall, with more substantial increases in WIC-authorized stores
Federal policy changes to the WIC program had the intended effect of increasing consumption of the prescribed food items.
The WIC-AI is a simple tool useful in summarizing complex food store environment data and may be adapted for use in other states or a national level to inform food policy decisions and direction
Fruit consumption increased among Hispanic mothers and low-fat dairy intake increased among Hispanic mothers, Hispanic children and African-American children. Changes in home food availability were not significantly correlated with changes in diet.
