Try the following data challenges:

1. Do an online search for what is considered a healthy weight for an 18-year-old. How does this compare to the average weight of youth in this dataset?
2. Examine the relationships between women who are pregnant and their age, marital status, education status, and household income. What trends do you notice?
3. Are certain groups more likely to be anemic than other groups? Can you predict how much iron a person has in his or her blood based on the individual’s age, race, or other factors?

The National Health and Nutrition Examination Survey (NHANES) is a population survey designed to collect information on the health and nutrition of the U.S. population. If you have ever wondered about the average height of, say, a 32-year-old male in the U.S., this dataset will provide that kind of information. Many health professionals have come across this data as part of their medical training. NHANES data has been used to improve the health of the U.S. population in several ways, including informing policies leading to the removal of lead from U.S. gasoline, creating pediatric growth charts, and estimating baseline standards for cholesterol, blood pressure, and Hepatitis C.

The NHANES program suspended field operations in March 2020 due to the coronavirus disease 2019 (COVID-19) pandemic. As a result, data collection for the NHANES 2019-2020 cycle was not completed and the collected data are not nationally representative. Therefore, data collected from 2019 to March 2020 were combined with data from the NHANES 2017-2018 cycle to form a nationally representative sample of NHANES 2017-March 2020 pre-pandemic data.
