Self-reported physical health practices and health care utilization: findings from the National Health Interview Survey.
Cross-sectional physical health practice and health care utilization data from the 1977 National Health Interview Survey were analyzed. After adjusting for the effects of age, sex, race, income, education, and marital status, there were significant relationships between hours of sleep and both doctor visits and hospital days; increased physical activity was associated with fewer doctor visits. Prospective intervention studies are needed to determine whether changes in health practices will lead to decreased utilization.
