Abstract
More than 45 million Americans—nearly one fifth of the non-Medicare population—lack health insurance.1 Lacking health insurance has serious negative health consequences.2 Research has demonstrated that uninsured adults are less likely than insured adults to receive preventive services, such as screening for breast, cervical, or colorectal cancer.3-6 Other studies have shown that lacking health insurance is associated with not receiving recommended treatment for chronic illnesses, such as diabetes,7 arthritis, or hypertension.8
