Description

For sample persons over age 18 in 1983 and over age 55 in 1984, this variable indicates if the respondent ever had hardening of the arteries. The condition did not have to be diagnosed by a doctor or health professional, and a definition of "hardening" was not provided in the survey text or in the Field Representative's Manuals . In 1983, the question used the phrase "hardening of the arteries" and in 1984 the question used the phrase, "hardening of the arteries or arteriosclerosis." According to the National Library of Medicine, the latter if a condition which is caused when fat and other substances "build up in the walls of arteries and form hard structures called plaques." Interviewers were instructed to circle the appropriate condition or circle both if necessary, although the NHIS and IPUMS NHIS do not provide separate variables.
