MJ Health Questionnaire Database

For population-based longitudinal studies, the "MJ Health Questionnaire Database" serves as an important research resource. This health questionnaire is divided into five major categories, containing over 100 items that include basic information, personal and family medical history, recent health surveys, lifestyle habits, and dietary habits. Since 1996, a substantial amount of data has been collected. Unlike typical medical databases that primarily gather information from "patients," the data from the "MJ Health Resource Center" includes a broad range of healthy and sub-healthy populations. Additionally, long-term health check-up data reported by participants is one of the most significant features of the "MJ Health Resource Center."

MJ Biochemical Examination Database

The "MJ Health Examination Database" includes data on over 100 health check items, encompassing basic physical measurements, blood tests, blood sugar, lipid levels, liver function, kidney function, lung function, bone density, tumor markers, thyroid function, inflammatory markers, stool tests, ENT evaluations, eye examinations, electrocardiograms, ultrasounds, chest and abdominal X-rays, gynecological assessments, and upper gastrointestinal X-rays, among others. Data digitization has been implemented since 1994, allowing for integration with the "MJ Health Questionnaire Database" for statistical analysis.
