Summary health statistics for U.S. adults: National Health Interview Survey, 1998

This report presents health statistics from the 1998 National Health Interview Survey for the civilian noninstitutionalized adult population, classified by sex, age, race and Hispanic origin, poverty status, and region of residence for chronic condition prevalence, health status and limitations in activity, health care access and utilization, health behaviors, and attitudes toward acquired immunodeficiency syndrome (AIDS). Health statistics by education, income, health insurance coverage, marital status, and place of residence are also presented for health status and limitations in activity, health care access and utilization, health behaviors, and knowledge and attitudes toward AIDS.

The NHIS is a multistage probability sample survey conducted annually by interviewers of the U.S. Census Bureau for the National Center for Health Statistics, Centers for Disease Control and Prevention, and is representative of the civilian noninstitutionalized U.S. population. Data are collected during face-to-face interviews with adults present at the time of the interview. Also, the self-reported health information for adults in this report was obtained from one randomly selected adult per family.

In 1998, 65% of adults 18 years of age and over reported excellent or very good health. However, 17% of adults less than 65 years of age had no health insurance coverage, and 14% of adults did not have a usual place of medical care. Twelve percent of adults had ever been told by a doctor or health professional that they had heart disease and 19% had been told on two or more visits that they had hypertension. Nearly a quarter of adults were current smokers, and 23% were former smokers. Sixty percent did not engage in any leisure-time vigorous physical activity, and based on estimates of body mass index, 35% were overweight and 20% were obese.
