National Health and Nutrition Examination Survey I: Epidemiologic Follow-Up Study, 1982-1984 (ICPSR 8900)
The National Health and Nutrition Examination Survey I Epidemiologic Followup Study (NHEFS) originated as a joint project between the National Center for Health Statistics (NCHS) and the National Institute on Aging (NIA). The design of NHEFS, which contains follow-up data on the NHANES I cohort, consisted of five steps. The first step focused on tracing and locating all subjects in the cohort or their proxies and determining their vital status. The second step involved the obtaining of death certificates for subjects who were deceased. Interviews with the participants or their proxies constituted the third phase of the follow-up. The fourth phase of the follow-up included measurements of pulse, blood pressure, and weight for interviewed respondents, and the fifth step was the acquisition of relevant hospital and nursing home records, including pathology reports and electrocardiograms. The respondent interview was designed to gather information on selected aspects of the subject's health history since the time of the NHANES I exam. This information included a history of the occurrence or recurrence of selected medical conditions, an assessment of behavioral, social, nutritional, and medical risk factors believed to be associated with these conditions, and an assessment of various aspects of functional status. Whenever possible, the questionnaire was designed to retain item comparability between NHANES I and NHEFS in order to measure change over time. However, questionnaire items were modified, added, or deleted when necessary to take advantage of recent improvements in questionnaire methodology. The Vital and Tracing Status file is a master file containing tracing, vital status, and demographic data for all NHEFS respondents. In addition, it provides users with information on the availability of different survey components for each respondent. For example, variables have been created to indicate whether a death certificate was received for a deceased subject, hospital records were received, or a follow-up interview was completed. The Health Care Facility Record file offers data on respondents who had reported an overnight stay in a health care facility after 1970. Information on the name and address of the facility, the date of the stay, and the reason for the stay was recorded. The Mortality Data file contains death certificate information for 1,935 NHEFS decedents. The death certificate information is for deaths occurring from 1971 to 1983.

Per agreement with NCHS, ICPSR distributes the data file(s) and technical documentation in this collection in their original form as prepared by NCHS. The NHEFS subject identification number (Sample Sequence Number) is located in tape positions 1-5. This number is unique for each subject and can be used when linking the NHEFS and NHANES I Public Use Data Tapes.
physical examinations, self-enumerated forms, and official records
Restrictions: In preparing the data tapes for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
