The National Health and Nutrition Examination Survey (NHANES) is a program designed to assess the health and nutritional status of adults and children in the United States conducted by the Centers for Disease Control and Prevention (CDC). Since 1999, the survey became a continuous program that examines a nationally representative sample of about 5,000 persons each year. Findings from this survey have been used to determine the prevalence of major diseases and risk factors for diseases.
Multiple studies published in the last five years using levels of metabolites of chlordane/heptachlor in the blood of Americans (NHANES)(1999-2006) reported that higher concentrations of heptachlor epoxide and oxychlordane increase the risk of cognitive decline,[Full Article, PDF] liver damage (liver enzymes),[PDF] peripheral arterial disease,[PDF] prostate cancer (trans-nonachlor),[PDF] type 2 diabetes,[PDF][PDF] and obesity ( waist circumference).[PDF]
In other large epidemiological surveys, higher levels of oxychlordane in both blood and adipose increased the risk of non-Hodgkin lymphoma,[PDF][PDF] and likewise higher concentrations of heptachlor epoxide in brain tissues increase the risk of Parkinson diseases.[PDF]
