The National Health and Nutrition Examination III will provide important data for examination of the health and nutritional status of persons in the U.S. Innovations in the study, particularly the inclusion of persons over age 74 and the focus of the survey on the major chronic diseases of old age, will enhance the value for older persons. Response rates for phase 1 (1988-1991) show that about 80% of all older subjects agreed to the interview; examination rates declined with age, but the use of a home examination increased the response rate for those aged 75 or older by about 9% to 67% for men and about 62% for women. Analytic plans include examination of the effect of nutrition on health, as well as the effect of health status on the distribution of nutritional risk factors in old age.
第三次全国健康与营养检查将为研究美国人群的健康和营养状况提供重要数据。该研究中的创新之处，尤其是纳入了74岁以上的人群以及将调查重点放在老年主要慢性病上，将提高对老年人的价值。第一阶段（1988 - 1991年）的应答率表明，所有老年受试者中约80%同意接受访谈；检查率随年龄下降，但采用上门检查使75岁及以上人群的应答率提高，男性提高了约9%，达到67%，女性达到约62%。分析计划包括研究营养对健康的影响，以及健康状况对老年营养风险因素分布的影响。
