Body Constitution Clinical Trial
Official title:
Epidemiological Study on Body Constitution Classified by Traditional Chinese Medicine Theory
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.
