Objectives: We analyzed state-specific uninsurance trends among US adults aged 18 to 64 years.
Methods: We used logistic regression models to examine Behavioral Risk Factor Surveillance System data for uninsurance from 1992 to 2001 in 47 states.
Results: Overall, uninsurance rates increased in 35 states and remained unchanged in 12 states. Increases were observed among people aged 30 to 49 years (in 34 states) and 50 to 64 years (in 24 states), and increases were also observed among individuals at middle and low income levels (in 39 states and 19 states, respectively), individuals employed for wages (in 33 states), and the self-employed (in 18 states).
Conclusions: Among adults aged 18-64, rates of uninsurance increased in most states from 1992 through 2001. Decreased availability of employer-sponsored health insurance, rising health care costs, and state fiscal crises are likely to worsen the growing uninsurance problem.
