National Health and Nutrition Examination Survey I: Epidemiologic Follow-up Study, 1992

The National Health and Nutrition Examination Survey I Epidemiologic Followup Study (NHEFS) is a longitudinal study that follows participants from the NHANES I who were aged 25-74 in 1971-1975. The NHEFS surveys were designed to investigate the association between factors measured at the baseline and the development of specific health conditions and functional limitations. Follow-up data were collected in 1982-1984 (ICPSR 8900), 1986 (ICPSR 9466), 1987 (ICPSR 9854), and 1992. The 1992 NHEFS collected information on changes in the health and functional status of the NHEFS cohort since the last contact period. The Vital and Tracing Status file (Part 1) provides summary information about the status of the NHEFS cohort. The Interview Data file (Part 2) covers selected aspects of the respondent's health history, including injuries, activities of daily living, vision and hearing, medical conditions, exercise, weight, family history of cancer, surgeries, smoking, alcohol use, and medical care utilization. The Health Care Facility Stay files (Parts 3 and 4) supply information about stays in hospitals, nursing homes, and mental health care facilities, as well as information abstracted from facility medical records. The Mortality Data file (Part 5) contains data abstracted from the death certificates for NHEFS decedents.

国家健康与营养调查一期流行病学随访研究（NHEFS）是一项纵向研究，对1971-1975年间年龄介于25至74岁的NHANES I参与者进行追踪调查。NHEFS调查旨在探究基线测量的因素与特定健康状况及功能障碍发展之间的关联。随访数据收集于1982-1984年（ICPSR 8900）、1986年（ICPSR 9466）、1987年（ICPSR 9854）以及1992年。1992年的NHEFS收集了自上次接触以来NHEFS队列健康和功能状态变化的信息。生命与追踪状态文件（第一部分）提供了关于NHEFS队列状态的综合信息。访谈数据文件（第二部分）涵盖了受访者健康史的选定方面，包括伤害、日常生活活动、视力与听力、医疗状况、锻炼、体重、癌症家族史、手术、吸烟、酒精使用和医疗保健利用情况。医疗设施停留文件（第三部分和第四部分）提供了关于住院、养老院和精神健康护理设施停留的信息，以及从设施医疗记录中摘录的信息。死亡率数据文件（第五部分）包含了从NHEFS去世者的死亡证明中摘录的数据。
