Background: Different people are classified into different physiological constitution types in the Traditional Chinese Medicine (TCM) theory. Two instruments, the Body Constitution Questionnaire (BCQ) and the Constitution in Chinese Medicine Questionnaire (CCMQ), have been developed in Taiwan and Mainland China respectively to measure constitution. They were adapted and pilot tested in primary care Chinese patients in Hong Kong, which showed acceptable validity and reliability. These instruments have potential applications for epidemiological studies on body constitution.
Aim and objectives: The aim of this study is to establish the prevalence and epidemiology of body constitution classified by the Traditional Chinese Medicine Theory in the Chinese population in Hong Kong. It would also determine whether the prevalence of constitution types change with seasons and whether it is associated with socio-demographic factors, place of origin or residence, life style, or quality of life.
Design and subjects: Two cross-sectional telephone surveys of the Hong Kong (HK) general Chinese population, one in Summer and one in Winter, will be carried out. Sample size for each survey is 3200 subjects.
Methods: Residential-telephone-owning households will be contacted through random dialing by the Social Science and Research Centre of the University of Hong Kong using the Computer-Assisted Telephone Interviewing (CATI) system that covers 95% households in Hong Kong. A member, aged 18 or above, of the contacted household who last had his/her birthday will be invited to the study to answer either the BCQ or the CCMQ and a structured questionnaire on socio-demographics, place of origin, place of residence, health service utilization, life style and quality of life.
