Reassessing the WIC effect: evidence from the Pregnancy Nutrition Surveillance System

Joyce T, et al. Reassessing the WIC effect: evidence from the Pregnancy Nutrition Surveillance System. J Policy Anal Manage. Spring 2008;27(2):277-303.

This study used data from nine states that participate in the Pregnancy Nutrition Surveillance System to address limitations in previous work. Studying the effects of the WIC Program, results suggested that the WIC effect in improving infant health exists, but on fewer margins and with less impact than has been claimed by policy analysts and advocates.
