|Description:||The National Center for Health Statistics (NCHS) has conducted the National Health and Nutrition Examination Survey (NHANES) continuously since 1999. One of the major components of NHANES is the nutrition and dietary component. A recent National Academies panel on Enhancing the Data Infrastructure in Support of Food and Nutrition Programs recommended linking the NHANES data with food assistance and other related program records to more fully understand decisions that the population makes on food consumption and to guide policy makers. NCHS has decided to link 2005-2008 NHANES data with Food Stamp Program and Temporary Assistance for Needy Families administrative records in Texas. If additional funds become available, NCHS will also link 2005-2008 NHANES data with Women, Infants, and Children (WIC) and Unemployment Insurance Wage File Reports in Texas.
Under the project, the Ray Marshall Center for the Study of Human Resources at the University of Texas in Austin will perform the linkage of records. After the linkage has occurred, statistical analyses will be conducted. The analyses will assess the participation in food program assistance and the effects of long term participation as it relates to food consumption and nutrition. In addition, the analyses will assess the accuracy of collecting this information in a self reported survey compared to the results of record linkage to an administrative database. The results from this linkage analysis will help gain understanding for future food and nutrition-related policy planning in the United States and perhaps future linkage projects.
