The Impact of the Special Supplemental Nutrition Program for Women, Infants, and Children on Child Health
利用美国第三次全国健康与营养调查数据，分析WIC营养计划对学龄前儿童健康的影响，发现参与该计划能显著改善儿童整体健康状况，尤其增加儿童处于极好健康状态的概率。
Data from the third National Health and Nutrition Examination Survey are used to analyze the effect of the Women, Infants, and Children (WIC) Program and other factors on the health of U.S. preschool children. Ordered probit equations are estimated for the physician's overall evaluation of the child's health. The WIC Program has a significant positive impact on the overall health of children. In particular, children in households participating in WIC are significantly more likely to be in excellent health. Increased household income also improves their health.
