老年男性握力増龄性变化横断面研究及与国外参考值比较

目的评估不同年龄层老年人的握力表现，并与国外参考值比较。方法112名老年人依其年龄分成65～69岁、70～74岁、75～79岁、80～84岁、85～89岁和90～95岁6组。通过Jamar握力器对受试者进行握力测量。结果握力与年龄之间呈现中度负相关（左侧：r=-0.681,P＜0.001；右侧：r=-0.68,P＜0.001）。逐步回归分析结果显示年龄因素可以解释47%右利手握力变化（R²=0.468, F=47.951,P＜0.001）。在75～79和85～89岁两个年龄段的握力下降程度较其他年龄段更为显著。结论老年人的握力随着年龄增大而呈逐渐下降趋势，在75岁以上老年男性人群中尤为明显。国外老年男性握力参考值并不适用于中国人。

Cross-sectional Study on Age-related Changes in Grip Strength of Elderly Men:Compared with Norms of Overseas

ObjectiveTo investigate the age-related changes in grip strength of the elderly men and compare with the norms of overseas. Methods112 subjects were divided into six groups: 65～69 years old, 70～74 years old, 75～79 years old, 80～84 years old, 85～89 years old, and 90～95 years old. The grip strength was measured with Jamar dynamometer. ResultsThe grip strength of both sides were significantly moderate negative correlated to age (r=-0.681 and -0.68, P<0.001) and stepwise regression analysis showed the age was important clinical factor to consider in determining grip strength in the elderly men （R²=0.468, F=47.951, P＜0.001). The grip strength was declined significantly during the 75～79 and 85～89 years old. ConclusionGrip strength had declined in the elderly men and these losses were significantly related to age. The highest loss in men was in the age over 75. The norms of grip strength overseas were not applicable to Chinese older adults.
