Data collection for the National Health and Nutrition Examination Survey (NHANES) comprises three levels: a household screener, an interview, and a physical examination. The primary objective of the screener is to determine whether any household members are eligible for the interview and examination. Eligibility is determined by the preset selection probabilities for the desired demographic subdomains. After selection as an eligible sample person, the interview collects person-level demographic, health, and nutrition information as well as information about the household. The examination includes physical measurements, tests such as eye and dental examinations, and the collection of blood and urine specimens for laboratory testing.
This report will first describe the broad design specifications for the 1999-2006 survey including survey objectives, domain and precision specifications, operational requirements, sample design, and estimations procedures. Details of the sample design are divided into two sections. The first section (NHANES 1999-2001 Sample Design) broadly describes the sample design and various design changes during the first three years of the continuous NHANES (1999-2001). The second section (NHANES 2002-2006 Sample Design) describes the final sample design developed and applied for 2002-2006. Weighting and variance estimation procedures are presented in the same manner; however, to correspond to the public data release cycles, the weighting and variance sections are separated into those used for 1999-2002, and those used for 2003-2006. Much of this report is based on survey operations documents and sample design reports prepared by Westat. Documentation of the survey content, procedures, and methods to assess nonsampling errors are reported elsewhere.
美国国家健康与营养检查调查（NHANES）的数据收集包括三个层面：家庭筛查、访谈和体格检查。筛查的主要目的是确定哪些家庭成员有资格接受访谈和检查。资格是根据所需人口子领域的预设选择概率来确定的。被选为合格样本个体后，访谈会收集个体层面的人口统计学、健康和营养信息以及有关家庭的信息。检查包括体格测量、眼科和牙科检查等测试，以及采集血液和尿液样本进行实验室检测。
本报告将首先描述1999 - 2006年调查的总体设计规范，包括调查目标、领域和精度规范、操作要求、样本设计以及估计程序。样本设计的细节分为两个部分。第一部分（1999 - 2001年NHANES样本设计）大致描述了连续NHANES（1999 - 2001年）前三年的样本设计及各种设计变更。第二部分（2002 - 2006年NHANES样本设计）描述了为2002 - 2006年制定并应用的最终样本设计。加权和方差估计程序以相同方式呈现；然而，为了与公共数据发布周期相对应，加权和方差部分分为用于1999 - 2002年的以及用于2003 - 2006年的。本报告的大部分内容基于Westat编写的调查操作文件和样本设计报告。调查内容、程序以及评估非抽样误差方法的文档在其他地方有报告。
