The National Health and Nutrition Examination Survey (NHANES), administered by the Centers for Disease Control and Prevention (CDC), collects extensive health and nutritional information from a diverse U.S. population. Though expansive, the dataset is often too broad for specific analytical purposes. In this sub-dataset, we narrow our focus to predicting respondents' age by extracting a subset of features from the larger NHANES dataset. These selected features include physiological measurements, lifestyle choices, and biochemical markers, which were hypothesized to have strong correlations with age.
For what purpose was the dataset created?
The NHANES dataset was created to assess the health and nutritional status of adults and children in the United States.
Who funded the creation of the dataset?
Centers for Disease Control and Prevention (CDC), specifically through its National Center for Health Statistics (NCHS)
What do the instances in this dataset represent?
Survey respondents throughout the United States
Data was gathered through interviews, physical examinations, and laboratory tests.
Was there any data preprocessing performed?
For this subset respondents 65 years old and older were labeled as “senior” and all individuals under 65 years old as “non-senior.”
