The National Health and Nutrition Examination Survey is underway in Stockton, operating out of mobile trailers at the Sherwood Mall.
San Joaquin is one of 15 counties chosen this year for the survey sampling the nation's health.
Researchers are compiling data from more than 500 people as they look at hearing, bone density, cholesterol, diabetes, oral hygiene and more.
Ryne Paulose with the National Center for Health Statistics said in this way the country’s population can be studied for high-risk factors. People are chosen and invited to be part of the study, and their data helps provide information aboout a larger group in the popuation.
In the past few years some groups, such as Asian-Americans, are oversampled to provide national estimates on their health conditions.
“We were able to look at obesity, diagnosed and undiagnosed hypertension, undiagnosed diabetes, various infectious diseases, nutritional status, and much more in this subgroup of the U.S. population,” Paulose said.
Paulose said these surveys have helped find the link between high cholesterol and heart disease, and fortifying cereals with vitamins for children’s health.
