National Health and Nutrition Examination Survey 2010-2012, Chemosenses Component

该协议的目的是为科学和技术支持提供资金，并为国家健康和营养检查调查（NHANES）中的化学感觉（嗅觉和味觉）检查和问卷部分提供质量保证，该调查由国家卫生统计中心（NCHS），疾病控制和预防中心（CDC）运营。NIDCD基金将支持将味觉和嗅觉的标准测量纳入这项具有全国代表性的、基于人口的调查，以确定美国味觉和/或嗅觉障碍的患病率，以及识别味觉/嗅觉丧失的风险因素和可能的相关状况，例如肥胖、改变的饮食摄入和慢性疾病（哮喘、心血管疾病等）。该议定书将在2010年国家健康和营养状况调查中进行试点测试和评估，然后在2011年及以后的国家健康和营养状况调查中在全国实施。该方案建立在标准临床测试程序，2006年比弗坝威斯康星州（BOSS研究）味觉测试，以及为NIH设计嗅觉和味觉测试方案的化学传感科学家的建议基础上。这似乎是在NHANES中添加味觉/嗅觉检查的适当时机，因为：1）2011年将首次添加几年来的完整牙科检查组件，以及2）NHANES营养流行病学家最近认识到添加嗅觉和味觉测试的价值，以增强广泛的NHANES饮食调查组件。每年将有大约2,000名年龄在40岁至85岁以上、来自不同种族和民族背景的成年人参加味觉和嗅觉考试。NIDCD已与NCHS/NHANES资助了一个IAA，NCHS将承包实地工作。

The purpose of this agreement is to provide funding for scientific and technical support as well as quality assurance for the chemosensory (smell & taste) examination and questionnaire components in the National Health and Nutrition Examination Survey (NHANES), which is operated by the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC). NIDCD funds will support incorporating standard measures of taste and smell into this nationally-representative, population based survey to determine the prevalence of taste and/or smell impairment in the U.S., as well as to identify risk factors for taste/smell loss and possible associated conditions such as obesity, altered dietary intake, and chronic illness (asthma, cardiovascular disease, etc.). The protocol will undergo pilot testing and evaluation in NHANES 2010 before implementation nationally in NHANES 2011 and beyond. The protocol builds upon standard clinical test procedures, the 2006¿2009 Beaver Dam Wisconsin (BOSS Study) taste exam, and the recommendations of the chemosensory scientists who have designed the smell and taste exam protocols for the NIH Toolbox. This seems to be an appropriate time to add taste/smell exams to NHANES, since: 1) there will be a full dental exam component for the first time in several years added in 2011, and 2) the NHANES nutritional epidemiologists have recently recognized the value of adding smell and taste testing to augment the extensive NHANES diet survey components. Approximately 2,000 adults, ages 40 to 85+ years, from diverse racial and ethnic backgrounds will participate each year in the taste and smell exam. NIDCD has funded an IAA with NCHS/NHANES and NCHS will contract the field work.
