National Health and Nutrition Examination Survey III, 1988-1994: Series II, No. 3A (ICPSR 4010)
Principal Investigator(s): United States Department of Health and Human Services. Centers for Disease Control and Prevention. National Center for Health Statistics
The third National Health and Nutrition Examination Survey (NHANES III, ICPSR 2231), conducted in 1988-1994, was designed to obtain nationally representative information on the health and nutritional status of the population of the United States through interviews and direct physical examinations. This release, Series II, No. 3A, contains data obtained from a second exam of selected survey participants who had had a primary exam. This release does not replace any previous NHANES III data releases. The second exam sample consists of seven separate data files. The Combination Foods file contains information on food weight, nutrient data, and descriptions about combination foods. The Total Nutrient Intake file records respondent intake of foods and beverages in a 24-hour time period. The Examination file consists of a comprehensive physical/dental examination. The Individual Foods file lists the food records and component food records for single and multi-component combination foods. The Laboratory file contains data collected through whole blood, serum, plasma, and urine specimens collected from respondents. The Second Laboratory file contains blood and urine assessments by specimen type and age group. The Variable Ingredient file reports data pertaining to the variable ingredients for many recipe foods in the Individual Foods file.
These data are available to the general public.

Scope of Study
Subject Terms: demographic characteristics, diet, disease, ethnicity, health behavior, health services utilization, health status, hospitalization, malnutrition, medical evaluation, nutrition, populations, risk factors, social indicators
Geographic Coverage: United States
Date of Collection:
Universe: The civilian noninstitutionalized population two months of age and over in the 50 states and the District of Columbia.
Data Types: clinical data, survey data
Data Collection Notes:
Per agreement with NCHS, ICPSR distributes the data files and text of the technical documentation for this collection as prepared by NCHS.
The second exam data files can be linked to the primary exam data and the household interview data using the unique identifier (SEQN). This is necessary to obtain the demographic data for the sample. Further, NCHS recommends that the survey design variables (e.g., sample weights) not be linked with these second exam data files, since the survey design variables were created for the full sample. There are no sample weights or other design variables specifically created for the second exam sample.
The codebook is provided by ICPSR as a Portable Document Format (PDF) file.
Sample: Select survey participants from the primary NHANES III who completed an exam. The primary survey used a complex, stratified, multistage, probability design.
personal interviews, laboratory reports, and clinical examinations
Restrictions: In preparing the data files for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution NCHS requires, under Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
