The National Health and Nutrition Examination Survey (NHANES) study is a continuous nationwide survey conducted by the Centers for Disease Control and Prevention with a goal of describing the “health and nutrition status of the adults and children of the United States”6. NHANES uses multi-stage probability cluster sampling of non-institutionalized persons to systematically collect data from a representative sample of the US population6. After an in-home survey to determine eligibility, participants travel to the local mobile examination center (MEC) to have a physical exam, blood draw, and to provide their first 24-hour dietary recall (24 h). Within 3–10 days, a second 24 h is conducted over the telephone. Data from both 24 h were used in this study.
