Eighteen percent of the non-disability-based adult Medicaid population is at high risk for developing type 2 diabetes.

Life-style change intervention programs to prevent type 2 diabetes in Medicaid beneficiaries at high risk for type 2 diabetes are likely to be cost effective in the long-term from a healthcare system perspective.

The cost effectiveness is lower from a narrow Medicaid perspective and the population-level health impact of intervening in beneficiaries at high risk for type 2 diabetes is small.
