Nutritional supplements in health-conscious pre-/ post-menopausal Thai women.
OBJECTIVE
To survey prevalence, knowledge, attitude, and factors affecting the behavior of nutritional supplement consumption in health-conscious pre-/post-menopausal Thai women.


METHODS
A survey was conducted in 327 women, aged 40-67 years, who were new participants in the health promotion education program of Siriraj Menopause Clinic, Gynecologic Endocrinology Unit, Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol University, between January and July 2008. The participants completed a self-administering questionnaire inquiring their demographic data, attitude, knowledge, and behavior of supplement consumption. The participants were divided into three groups, i.e., current-, past-, and never-users, and then compared.


RESULTS
The majority (54.7%) of the presented participants consumed at least one kind of supplements, 37.3% and 17.4% were current-and past-users, respectively. The current-, past-, and never-users were not different in age, medical diseases, education levels, reading frequency, and economic status. The majority of participants obtained the information ofsupplements from newspaper or magazine. The users primarily purchased the supplements from hospitals or clinics. All participants had knowledge on health promotion and supplement products, however, 7.6% and 11.5% of such knowledge, respectively, was inaccurate. All participants had both positive and negative attitudes on supplement consumption, the negative attitude was found in 33.4% of the items tested. The never-users had trivial but statistically significant (p < 0.001) more accurate knowledge and more negative attitude than other groups had.


CONCLUSIONS
More than 50% of health-conscious pre-/post-menopausal Thai women are ever-users of nutritional supplements. A lot of misunderstanding and misconception do exist even in the health-conscious women, regardless of their consumption behaviors. More education on this issue should be provided in order to reduce unnecessary expenditure and increase the efficiency of supplement consumption expenditure.
