About 1.5 million uninsured children in California are eligible for Medi-Cal or Healthy Families, the state's primary public health insurance programs for children. The Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides a natural entry point for reaching these eligible families. This briefing report was written for WIC specialists, health professionals, agency officials, and policymakers to provide a road map of policy strategies for increasing health insurance outreach and enrollment activities through WIC sites. The report includes a brief review of the WIC, Medi-Cal, and Healthy Families programs, and a look at the data available on the health insurance status of children enrolled in WIC. The report also presents an examination of WIC's current health insurance outreach and enrollment activities, including a look at some California best practices and models elsewhere in the nation. This framework is followed by an analysis of some of the challenges involved with strengthening California WIC's linkage to health care, and recommendations for moving forward. (EV)
