Carlson A, Senauer B. The impact of the Special Supplemental Nutrition Program for Women, Infants, and Children on child health. Am J Agric Econ. 2003;85(2):479-491.
The authors used data from the third National Health and Nutrition Examination Survey (NHANES) to analyze the effect of the WIC Program and other factors on the health of US preschool children. Findings revealed that the WIC Program had a significant positive impact on the overall health of children. In particular, children in households participating in WIC were significantly more likely to be in excellent health.
