Nonresponse and intensity of follow-up in an epidemiologic study of Vietnam-era veterans.
Veterans who could not be located were more likely than respondents to possess baseline characteristics predictive of increased mortality.
In contrast, subjects who were located but refused to be interviewed were similar to respondents.
Among veterans who were interviewed, those who were hardest to locate had the highest prevalence of known risk factors for diminished health status and reported many health problems with higher relative frequencies than respondents who were easier to locate.
