| Sumario: | The National Health Examination Surveys, Cycle I (NHES I), conducted during the period 1959-1962, were designed to secure statistics on the health status of the population of the United States. More specifically, their purpose was to determine the prevalence of certain chronic diseases, the status of dental health, and the distributions of auditory and visual acuity and certain anthropometric measurements. This collection contains demographic, household, and personal information for each sample person including age, race, sex, income, region, size of residence, usual activity, and sampling weight. Also included are responses to 12 items from a medical history questionnaire that were selected as indicators of psychological distress. The items include past experiences with such symptoms as faintness, sleeping problems, and sweaty hands.
