Abstract

Objectives : To assess the prevalence of osteoporosis in a rural community and to elucidate the related factors of this health problem in order to develop educational methods for the prevention of residents osteoporosis as well to provide basic data for prospective research. Methods : Over a period of forty-five days starting from January, 2006, 986 subjects whose age of 40 through 70 and living in Bongwhang Township, Naju City, Chollanamdo were interviewed and examined. To find the related factors with osteoporosis, 394 persons with osteopenia were excluded for the convenience of analysis. The criteria of osteoporosis are based on T-score measurement values. A T-score from -1.0 to -2.4 is considered to reflect "osteopenia", while a T-score below -2.5 is considered to reflect "osteoporosis". To accomplish the goal of study, χ2-test and multiple regression analysis were performed with SPSS 12.0. Results : The prevalence of osteoporosis among the subjects was 17.0%. For men, multiple logistic regression analysis showed that the odds ratio(OR) of osteoporosis among middle and higher as compared to non education was 0.28(95%CI 0.10-0.78). The OR of osteoporosis among smokers against non smokers was 3.11(95%CI 1.32-7.29). The OR of osteoporosis among drinkers against non drinkers was 0.44(95%CI 0.20-0.97). For women, multiple logistic regression analysis showed that the OR of osteoporosis among elementary as compared to non education was 0.34(95%CI 0.16-0.73). The OR of osteoporosis among subjects who had fracture history against no experienced persons was 2.85(95%CI 1.22-6.66). The OR of osteoporosis among subjects whose BMI(body mass index) were 25kg/㎡ or more against lower than 25kg/㎡ was 0.32(95%CI 0.15-0.70). The OR of osteoporosis among subjects whose WHR(waist hip ratio) 0.9 or more against lower than 0.9 was 2.58(95%CI 1.18-5.64). The OR of osteoporosis among subjects who had started menarche later than 20 years old as compared to subjects who had started menarche before 15 years old was 4.73(95%CI 1.27-17.7). Conclusions : Smoking was the risk factor, while high education and drinking were the protective factors for osteoporosis in men. Fracture history, abdominal obesity and later menarche age were the risk factors, while high education and high body mass index were the protective factors for osteoporosis in women.
