EXPACT NHANES dataset

The dataset is used in EXPACT: Explainable complex machine learning prediction of all-cause mortality in the U.S.The National Health and Nutrition Examination Survey (NHANES) from the National Center for Health Statistics (NCHS) \footnote[1]{http://www.cdc.gov/nchs/nhanes.htm} conducts interviews and physical examinations to assess the health and nutrition data for all ages in the United States. The interviews include demographic, socioeconomic, dietary, and health-related questions. The examinations include medical, dental, physiological measurements, and laboratory tests administered by highly trained medical personnel. Since 1999, data was collected and released at 2-year intervals. Each year NHANES examines a nationally representative sample of roughly 5,000 individuals across the Unites States. In this study, we include NHANES data sampled between 1999 and 2014. All-cause mortality is ascertained by a linked NHANES mortality file that provides follow-up mortality data from the date of survey participation through December 31, 2015.Our study includes samples with known mortality status who participated in NHANES 1999-2014 (n = 47,261). We include all demographic, laboratory, examination, and questionnaire features that could be automatically matched across different NHANES cycles.
