Announcement: NHANES 50th Anniversary and Conference

NHANES has long been a primary source of data on the nation's health. NHANES findings were used to set the goals and track the progress in reducing cholesterol levels, the prevalence of high blood pressure, and the risks of blood lead exposure in the United States. NHANES documented the rise in obesity and diabetes and produced the first population-based estimates of human immunodeficiency virus infection and osteoporosis. NHANES data also are used for the growth charts by which pediatricians and parents check children's growth and development.

A hallmark of NHANES is its partnerships with other CDC programs, the National Institutes of Health, other U.S. Department of Health and Human Services programs, and other government agencies to collect data needed for public health policies and practice. Additional information about the NHANES 50th anniversary is available at http://www.cdc.gov/nchs/nhanes/nhanes50th.htm.
