| Summary: | 碩士 === 亞洲大學 === 健康管理研究所 === 94 === The purpose of this study was to predict bone mineral density (BMD) from lifestyle factors. Seven hundred males and females aged 21 to 93 years received BMD examinations at a teaching hospital in Taichung since June 2005 to December 2005. We measured BMD by dual energy X-ray absorptiometry (DXA) at lumbar spine and bilateral femoral necks. Personal life styles including tobacco smoking, alcohol drinking, coffee consumption, exercise, milk consumption, Ca supplementation were also collected by a self-reported form at the BMD examination. Binary logistic regressions were performed for the prediction of BMD conditions. The result indicated that age, body weight, exercise and history of bone fracture are effective predictors of bilateral femoral necks BMD. Age, body weight, coffee consumption, smoking, and history of fracture are effective predictors of lumbar spine BMD. Menopause is an effective predictor of female BMD also. Regular physical activity and maintaining a normal weight are recommended for a healthy BMD.
