National Health Interview Survey, 1975: Physical Fitness Supplement (ICPSR 9762)

Principal Investigator(s):


The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. The 1975 Physical Fitness Supplement provides variables from the core Person File (see HEALTH INTERVIEW SURVEY, 1975 [ICPSR 7672]) including sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. The variables unique to this supplement include type of exercise in which respondent engaged (biking, calisthenics, jogging, lifting weights, swimming, walking), type of sports played (basketball, bowling, football, golf, softball, swimming, tennis), and level of participation (participant, team member, tournament).
