NHANES I (National Health and Nutrition Examination Survey I) Epidemiology Followup Study (NHEFS), Vital and Tracing Status, 1986. Public Use Data Tape Documentation

摘要

The NHANES I Epidemiologic Followup Study (NHEFS) is a longitudinal study which uses as its baseline those adult persons ages 25-74 years who were examined in 1971-75 in the first National Health and Nutrition Examination Survey (NHANES I). The first followup data collection wave was conducted in 1982-84 for subjects (i.e., NHANES I participants) who were 25-74 years old at their NHANES I examination (n=14,407). The next wave, the 1986 NHEFS, was conducted for subjects aged 55-74 years at NHANES I and not known to be deceased at the 1982-84 NHEFS (n=3,980). As with the 1982-84 NHEFS, the design of the 1986 NHEFS consists of four components: tracing subjects (or their proxies); conducting subject and proxy interviews; obtaining hospital and nursing home records; and acquiring death certificates. The 1986 NHEFS Vital and Tracing Status Public Use Data Tape contains vital status, tracing and demographic information on all subjects 55 years or older at NHANES I (n=5,677) and may be linked to all other NHEFS and NHANES I Public Use Data Tapes.
