绝经后女性握力和体重指数与骨密度的相关研究

Relation of grip strength, bone mineral density and body mass index in postmenopausal women

目的 探讨绝经后女性握力和体重指数与骨密度之间的相关性.方法 收集2012年3月至2013年3月在天津市红桥医院检查治疗973名女性志愿者,所有志愿者均接受足跟部骨密度测量（T指数）、握力测试和体重指数测量并进行相关性分析.结果 在单变量分析中,握力和体重指数与T指数相关（Pearson相关系数分别为0.201、0.115,P=0.001、0.009）,年龄与T指数呈负相关（Pearson相关系数为-0.358,P=0.001）.骨质疏松发病率18.7％（182/973）.有骨质疏松和无骨质疏松绝经年龄、握力比较[绝经年龄（48±6）岁比（49±5）岁,P=0.020;握力（23±6）kg比（24±6） kg,P=0.001].结论 体重指数和握力二者均与骨密度密切相关,二者可作为预示骨疾病的关键因子.

Objective To study the positive association between hand grip strength and bone mineral density in postmenopausal women.We conducted a screening program for osteoporosis in a large cohort of postmenopausal women to investigate the relation among hand grip strength,other nutritional parameters and bone density.Methods This investigation involved 973 volunteers from March 2012 to March 2013 at Tianjin Hongqiao Hospital.Bone mineral density,hand grip strength measurement,body mass index and T score were analyzed.Results Univariate analysis showed that hand grip strength measurement,body mass index and T score were correlated （Pearson correlation coefficient were 0.201,0.115,P =0.001,0.009） ; age and T score were negatively correlated（Pearson correlation coefficient were-0.358,P =0.001）.Incidence of osteoporosis was 19.7% （192/973）.Conclusion Both body mass index and handgrip strength are strongly correlated to bone mineral density.
