From staff reports:

The National Health and Nutrition Examination Survey (NHANES), the most comprehensive study of the health and nutritional status of the U.S. population, gets under way in King County beginning Sept. 23.

The survey will target 1,000 households in King County, including the Federal Way area. Results help develop health policies and programs. Each year, about 7,000 residents are randomly selected in 15 total counties across the nation.

All participants receive an examination by a physician, as well as a dietary interview, and body measurements that include height and weight. Some will be eligible for a hearing test, a scan to evaluate body fat, a breathing test, as well as a blood pressure test.
