正常老年男性的握力與橈骨骨質密度之關係

Abstract

The purpose of this study is to investigate the relationship between grip strength and bone mineral density (BMD ) in normal elderly males who were subject to senile osteoporosis. We examined grip strength and BMD in 49 healthy volunteer males, aged 65-80 years-old ( mean age : 71.1 + 3.9 y/o). Radial BMD was measured in the distal and middle radius by dual energy X-ray absorptiometry ( DEXA ). Isometric grip strength was assessed with a hand-held dynamometer for both forearms. A significant positive correlation was found between radial BMD and grip strength in both dominant and non-dominant forearms. Meanwhile, no significant correlation existed between body weight and radial BMD. In addition, we also compared the radial BMD between life style active/ sedentary groups, and smoker/ non-smoker groups. The two-tail paired t-test showed significant difference between life style active/sedentary groups, but no significant difference between smoker/non-smoker groups. We conclude that grip strength can be a predictor of radial BMD in elderly men, and habitual physical activity is one of the major determinants of BMD especially for aged male subjects.
