The National Health and Nutrition Examination Survey (NHANES) will be conducting a survey in Polk County beginning April 6 through June 6. A sample of about 619 people from Polk County will be asked to participate in the survey. Interviewers will be knocking on the doors of randomly selected households throughout the county. They will conduct a brief questionnaire at the doorstep in order to obtain demographic information used to identify sample participants for the survey. 

The NHANES interview includes demographic, socioeconomic, dietary, and health-related questions. The examination component consists of medical, dental, and physiological measurements, as well as laboratory administered tests by highly trained medical personnel. 

Findings from this survey will be used to determine the prevalence of major diseases and risk factors for diseases. Information will be used to assess nutritional status and its association with health promotion and disease prevention. NHANES findings are also the basis for national standards for such measurements as height, weight, and blood pressure.
