Cohort Profile: The Guangzhou Biobank Cohort Study, a Guangzhou–Hong Kong–Birmingham collaboration

Abstract
The Guangzhou Biobank Cohort Study (GBCS), initiated by TH Lam (Hong Kong), CQ Jiang (Guangzhou), and KK Cheng (Birmingham), has been in part modelled on the Kadoorie Study of Chronic Disease in China (KSCDC)1 and the UK Biobank.2 Initial seed funding came from the Universities of Hong Kong and Birmingham, the Guangzhou No. 12 Hospital (Guangzhou Occupational Disease Prevention & Treatment Centre), the Guangzhou Public Health Bureau, and the Guangzhou Science and Technology Bureau. The Clinical Trials Service Unit at Oxford University has provided technical advice, especially in the planning and setting up of the project.
