Younger Siblings Can Be Good for Your Health: An Examination of Spillover Benefits from the Supplemental Nutrition Program for Women, Infants, and Children (WIC)

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a food assistance program designed to
help pregnant (or postpartum) women and young children consume a nutritious diet. With WIC’s emphasis on providing healthy
foods, and food being (generally) a communal commodity, age-ineligible children may benefit from living with a WIC participant.
This paper used data from the third National Health and Nutrition Examination Survey to examine whether age-ineligible children
who lived in WIC households were in better health than similar children who lived in households that did not participate in
the program. Results suggested that older males received a health benefit as a result of living in a WIC household; however,
no similar effect was found for younger males or for female children.
