|Title:||National Health Interview Survey (NHIS), 1975 [United States]|
|Primary Investigator(s):||United States Department of Health and Human Services. National Center for Health Statistics (NCHS)|
|Abstract:||The purpose of the Health Interview Survey 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. There are five types of records in this core survey, each in a separate data file. The variables in the Household File (Part 1) include type of living quarters, size of family, number of families in the household, presence of a telephone, number of unrelated individuals, and region. The Person File (Part 2) includes information on sex, age, race, marital status, Hispanic origin, education, veteran status, family income, family size, major activities, health status, activity limits, employment status, and industry and occupation. These variables are found in the Conditions, Doctor Visits, and Hospital Episodes Files as well. The Person File also supplies data on height, weight, bed days, doctor visits, hospital stays, years at residence, and region variables. The Conditions File (Part 3) contains information for each reported health condition, with specifics on injury and accident reports. The Hospital Episodes File (Part 4) provides information on medical conditions, hospital episodes, type of service, type of hospital ownership, date of admission and discharge, number of nights in hospital, and operations performed. The Doctor Visits File (Part 5) documents doctor visits within the time period and identifies acute or chronic conditions.|
