Currently, one in every seven adolescents, aged 10-18, is uninsured. This translates to nearly 5 million uninsured adolescents nationwide. Uninsured adolescents, as opposed to insured adolescents, are more likely to be members of poor and minority families. In addition, adolescents without health insurance use fewer health services than their insured counterparts even after controlling for health status differences. Improving the health insurance status of adolescents is becoming an important public policy objective, although Congress recently rejected legislation that would have expanded Medicaid coverage for poor adolescents. Despite this setback, legislators and child health associates are increasingly striving for public and private insurance expansions for adolescents. These efforts are described, and the prospects for future improvements in health insurance coverage of adolescents are discussed.
