In 1989, the Child Nutrition and WIC Reauthorization Act increased the amount of eligible program participants by allowing groups such as Medicaid, Aid to Families with Dependent Children (AFDC), Temporary Assistance for Needy Families (TANF), and those qualified for food stamps automatically became eligible for WIC assistance. Allowing these groups to be eligible, in effect, raised the income eligibility threshold for WIC services. Participants in the WIC program are now viewed as those that are inherently eligible because of an income at 185% below the poverty line or adjunctively eligible through eligibility and participation in the aforementioned programs. Research has identified an increase in health benefits among WIC program participants that could offset the additional costs of Medicaid in the future. Changes in welfare benefits are also estimated to increase the adjunctive eligibility rate.
