Prevalence of Sedentary Leisure-time Behavior Among Adults in the United States Data from the newly released 1997 National Health Interview Survey show that 4 in 10 U.S. adults say that they NEVER engage in any exercises, sports, or physically active hobbies in their leisure time. Estimates of sedentary behavior shown here are based on responses to a series of questions asking how often and how long respondents engaged in leisure physical activities for at least 20 minutes that caused sweating or changes in their heart rate or breathing. Sedentary behavior has been identified as a risk factor for a variety of chronic health conditions, including coronary heart disease, hypertension, colon cancer, and diabetes mellitus.
The National Health Interview Survey is a survey of the non-institutionalized civilian population, conducted continuously throughout each year. The survey has been conducted since 1957 and underwent a major redesign of its questionnaire and of its data capture instrument in 1997. These findings are the first published from the new design. Physical activity questions were self-reported. Occupation, home, and transportation-related activities are all important contributors to the total picture of physical activity among adults, but due to constraints on the length of the survey these could not be assessed in the 1997 NHIS.
