The NHIS database includes an eligibility database for all demographic data (age, sex, socioeconomic variables, type of eligibility), a medical treatment database (diagnoses encoded by the International Classification of Disease, Tenth Revision of Clinical Modification [ICD-10], treatment, and prescription at inpatient and outpatient services), a health examinations database (anthropometric measurements, regular blood tests, and self-reported questionnaires on lifestyle factors and medical history), a medical care institution database (types of medical care institutions, location, equipment, and number of physicians), and death information [ 14 ].
