Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Tzu Chi Vegetarian Study (TCVS) recruited 12062 community volunteers of the Buddhists Tzu Chi Foundation throughout Taiwan in the year 2005. All participants completed a self-administered questionnaire on basic information, medical history, lifestyle, and diet.

The Tzu Chi Health Study (TCHS) recruited 6002 participants who came to the Buddhist Tzu Chi Dalin General Hospital for health examination. All participants were interviewed on basic information, medical history, lifestyle, and diet. Biochemical and anthropometric data was collected through a health examination:

Biochemical variables: CBC, fasting glucose, lipid profile (TCH, LDL, HDL, TG), BUN, Cr, ALT, AST, and UA. In addition, homocysteine, serum vitamin B12, folate, and C-reactive protein (CRP) are available for 1500 subjects.

Blood: Extra blood samples have been obtained and stored for 3500 subjects and will be available for future investigation.

Anthropometric variables: body weight, height, waist circumference, % body fat (with BIA), blood pressure, pulse wave velocity, bone mineral density through DXA (at spine for female and hip for male), lung function test (spirometric), abdominal sonography, colonoscopy, esophageal-gastro-duodenal-scopy, chest X-ray, KUB.

Follow-up: Individual baseline data were linked to the National Health Insurance Database and the National Death Registry to ascertain disease outcomes at the Health and Welfare Data Science Center.
