The National Health and Nutrition Examination Survey (NHANES)--

The National Health and Nutrition Examination Survey (NHANES)--(0920-0237)--Revision--National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC). This three-year clearance request includes the data collection in 2009 and 2010 and data planning and testing activities for 2011-2012 data collection. NHANES programs produce descriptive statistics which measure the health and nutrition status of the general population. Through the use of questionnaires, physical examinations, and laboratory tests, NHANES studies the relationship between diet, nutrition and health in a representative sample of the United States. NHANES monitors the prevalence of chronic conditions and risk factors related to health such as arthritis, asthma, osteoporosis, infectious diseases, diabetes, high blood pressure, high cholesterol, obesity, smoking, drug and alcohol use, physical activity, environmental exposures, and diet. NHANES data are used to produce national reference data on height, weight, and nutrient levels in the blood. Results from more recent NHANES can be compared to findings reported from previous surveys to monitor changes in the health of the U.S. population over time. NHANES continues to collect genetic material on a national probability sample for future genetic research aimed at understanding disease susceptibility in the U.S. population. NHANES data users include the U.S. Congress; the World Health Organization; numerous Federal agencies such as the National Institutes of Health, the Environmental Protection Agency, and the United States Department of Agriculture; private groups such as the American Heart Association; schools of public health; private businesses; individual practitioners; and administrators. NHANES data are used to establish, monitor, and/or evaluate recommended dietary allowances, food fortification policies, environmental exposures, immunization guidelines and health education and disease prevention programs. This submission requests approval for three years.
