Complementary and alternative medicine use in multiracial Singapore

OBJECTIVE: To determine the prevalence of complementary and alternative medicine (CAM) use in Singapore, the factors influencing CAM use, and the attitudes, beliefs and perceptions of the general population towards CAM. DESIGN: An interviewer-administered questionnaire survey in a housing estate with demographic and socioeconomic characteristics closely matching that of Singapore. RESULTS: 76% (95% C.I. 73.9-77.9%) used CAM over a 12-month period. Females were 2.1 times (95% C.I. 1.3-3.4) more likely than males to use CAM. Chinese (84%) were the most frequent users, followed by Malays (69%) and Indians (69%), with adjusted odds ratios of 0.4 (95% C.I. 0.2-0.7) for Malays and 0.4 (95% C.I. 0.2-0.8) for Indians. Traditional Chinese Medicine (88%) was the most widely used form of CAM, followed by Traditional Malay (Jamu) Medicine (8%) and Traditional Indian (Ayuverdic) Medicine (3%). Similar to western studies, CAM was more likely to be used for maintenance of health than for treatment of illness. Different from western studies, CAM use was not independently associated with household income, marital status, age and education. Seventy-four percent did not discuss their use of CAM with their western-trained doctors. CONCLUSIONS: The high prevalence of CAM use in multi-racial Singapore suggests the same may be true in other Asian countries. Western-trained doctors need to understand CAM better and communicate more with their patients regarding CAM use. The lack of a scientific evidence base for most forms of CAM notwithstanding, its ubiquitous use worldwide is something that governments and the medical profession cannot afford to ignore.
