Gueorguieva R, Morse SB, Roth J. Length of prenatal participation in WIC and risk of delivering a small for gestational age infant: Florida, 1996–2004. Matern Child Health J. Jul 2009;13(4):479-488.
The objective of this study was to assess the association between length of prenatal participation in the WIC Program and a marker of infant morbidity. The researchers found that the risks of delivering a small for gestational age, very preterm, or late preterm infant significantly decreased with WIC participation for a small dose response relationship.
