Studies show WIC helps :

•  reduce miscarriages and get babies off to a healthier start.
•  reduce premature births.
•  increase the birth weight of newborns.
•  decrease the incidence of iron deficiency anemia in children.
•  improve the diets of women who are pregnant or have recently given birth.
•  achieve recommended weight gain throughout pregnancy.
•  increase early prenatal care.
•  improve children's diet to make them healthier.

WIC participation has also been associated with improved intakes of protein, calories and other nutrients which often are inadequate in the diets of low income pregnant women and children. Improved utilization of immunization services by children has also been found.
