绝经后女性握力与骨密度的相关性研究

摘要

目的 研究绝经后女性握力和骨密度的相关性.方法 对120例绝经后女性进行握力测量和骨密度测定,观察≤60岁组、61 ～ 70岁组和＞70岁组的握力和骨密度变化,应用单因素Person相关性分析和散点图研究握力与骨密度的相关性.结果 最大握力:≤60岁组25.86 ±4.77 kg,61 ～ 70岁组23.37±4.64 kg,＞70岁组16.63 ±5.40 kg.骨密度测定提示:65例股骨颈T值≤-2.5;90例腰椎T值≤-2.5.最大握力与骨密度均随年龄增加而减少.握力与股骨颈和腰椎骨密度呈非常显著正相关.结论 绝经后女性握力越大,股骨颈和腰椎骨密度越高.%Objective To study the correlation between handgrip and bone mineral density (BMD) in postmenopausal women.Methods The handgrip and BMD were measured in 120 postmenopausal women.The patients were divided into ≤60 yrs group,61-70 yrs group,and ＞ 70 yrs group.The effect of age on handgrip and BMD was studied.The correlation between handgrip and BMD was studied with univariate Persons analysis and scattered diagram.Results The maximal handgrip was 25.86 ±4.77 kg in the patients aged ≤60 yrs,23.37 ± 4.64 kg in the patients aged 61-70 yrs,and 16.63 ± 5.40 kg in the patients aged ＞ 70yrs.BMD showed that 65 patients had T score ≤-2.5 at the femoral neck and 90 patients had T score ≤-2.5 at the lumbar spine.The handgrip and BMD decreased with increase of age in postmenopausal women.Conclusion The greater handgrip it is,the higher BMD at the femoral neck and lumbar spine in the postmenopausal women.
