Background : The bone mineral densities of men decrease with increasing age like women. The incidence of osteoporosis gradually increase according to increasing proportion of older people, but the studies on osteoporosis of men are now beginning. The association between the bone mineral density and behavioral factors among adult men in Korea were studied.
Methods : The study subjects who visited health promotion center of one hospital located in Seoul from April to May 2001, aged 28 to 76 years, were all mearsured bone mineral density at left calcaneus using quantitative ultrasonography (QUS). We interviewed all subjects to get the information about past medical history and behavioral risk factors such as smoking, drinking, intake of dairy food, and exercise patterns. We also checked height, weight, blood chemistry including alkaline phosphatase and Prostate Specific Antigen. We calculated the Pearson’s partial correlation coefficient between Speed of Sound (SOS) and each variables after adjusting age and body weight, and compare the mean SOS among each categories of the variables using Analysis of Covariance (ANACOVA). Finally, multiple regression analysis was done, using the model including significant variables of baseline analysis.
Results : One hundred six men, who did not have any metabolic disease influencing bone mineral density, were included. Age and smoking amount were negatively correlated and body weight was positively correlated with SOS. In univariate analysis, exercise, past history of fracture and dairy food intake was significantly associated with bone mineral density of men. In multiple regression analysis, body weight and dairy food intake were positively associated, but age and smoking amounts were negatively associated with bone mineral density.
Conclusion : To increase bone mineral density of men, one should maintain adequate body weight, ingest dairy food regulary and reduce smoking amount or quit smoking.
