The National Health and Nutrition Examination Surveys (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The NHANES combines personal interviews and physical examinations, which focus on different population groups or health topics. These surveys have been conducted by the National Center for Health Statistics (NCHS) on a periodic basis from 1971 to 1994. In 1999, the NHANES became a continuous program with a changing focus on a variety of health and nutrition measurements designed to meet current and emerging concerns. The sample for the survey is selected to represent the U.S. population of all ages. Many of the NHANES 2001-2002 questions also were asked in NHANES II 1976-1980, Hispanic HANES 1982-1984, NHANES III 1988-1994. New questions were added to the survey based on recommendations from survey collaborators, NCHS staff, and other interagency work groups. In the 2001-2002 wave, the NHANES includes more than 100 datasets. Most have been combined into three datasets for convenience. Each starts with the demographic dataset and includes datasets of a specific type. 1. National Health and Nutrition Examination Survey (NHANES), Demographic and Examination Data, 2001-2002 (the base of the Demographic dataset + all data from medical examinations). 2. National Health and Nutrition Examination Survey (NHANES), Demographic and Laboratory Data, 2001-2002 (the base of the Demographic dataset + all data from medical laboratories). 3. National Health and Nutrition Examination Survey (NHANES), Demographic and Questionnaire Data, 2001-2002 (the base of the Demographic dataset + all data from questionnaires). Not all files from the 2001-2002 wave are included. This is for two reasons, both of which related to the merging variable (SEQN). For a subset of the files, SEQN is not a unique identifier for cases (i.e. some respondents have multiple cases) or SEQN is not in the file at all. The following datasets from this wave of the NHANES are not included in these three files and can be found individually from the NHANES website at the CDC: Examination: Dietary Interview (Individual Foods File) Examination: Dual Energy X-ray Absorptiometry (DXX) Examination: Dual Energy X-ray Absorptiometry (DXX) Questionnaire: Analgesics Pain Relievers Questionnaire: Dietary Supplement Use -- Ingredient Information Questionnaire: Dietary Supplement Use -- Supplement Blend Questionnaire: Dietary Supplement Use -- Supplement Information Questionnaire: Drug Information Questionnaire: Dietary Supplement Use -- Participants Use of Supplement Questionnaire: Physical Activity Individual Activity File Questionnaire: Prescription Medications Variable SEQN is included for merging files within the waves. All data files should be sorted by SEQN. Additional details of the design and content of each survey are available at the NHANES website.
