Description: 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 followup 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 followup. The fourth phase of the followup 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.
Notes: The National Health and Nutrition Examination Surveys were designed to measure the nutritional status and health of the U.S. population. The first NHANES, conducted during the period 1971-1975, collected these data on a sample of the U.S. population ages 1-74 years, and obtained more detailed information on the health status and medical care needs of adults ages 25-74 years in the civilian non-institutionalized population. Information obtained includes a detailed dietary interview, general medical histories and detailed histories of respiratory disease, cardiovascular disease, and arthritis, health care needs and general well-being questionnaire, a general medical examination, dental, dermatological, and ophthalmological examination, anthropometry, vision and speech tests, data on X-rays of the hands, knees, hips, and chest, blood and urinary laboratory tests, electrocardiogram results, spirometry and pulmonary diffusion tests, and tap water samples. There were a total of 32,331 sample persons of which 31,973 were interviewed and 23,808 were examined. Some of the data files contain a smaller number of respondents.

LRECL format. 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. The data contain ampersands (&), dashes (-), and blanks ( ). 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 followup 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 were 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.
