80岁以上长期卧床患者握力与营养状况的关系

目的探讨评估长期卧床的80岁以上老人营养状况的简便、有效的方法。方法采集22例卧床时间〉1年的80岁以上患者的空腹静脉血，检测白蛋白和血红蛋白水平，并采用JAMAR握力器分别测试其左、右手的握力。结果本组高龄老年人左、右手握力与白蛋白水平均呈正相关（r=0．439，r=0．424，P〈0．05），与年龄和血红蛋白无相关性。结论长期卧床的高龄患者握力与其营养状态有显著相关性，可采用握力测试其营养状态。

The association between grip strength and nutritional status in bed-ridden patients aged more than 80 years old

Objective To study the association between grip strength and nutritional status in bed-ridden patients aged more than 80 years old. Methods The venous blood among twenty-two older than 80 years patients who were bed-ridden for more than 1 year were collected and the serum albumin and hemoglobin were analyzed. The left and right hand grip strength were tested with JAMAR Hand Dynamometer. Results Hand-grip strength was positively correlated with serum albumin (r=0.439 and 0.424, P<0.05). Pearson correlation showed that age and hemoglobin were significant independent predictors of hand-grip strength. Conclusions Hand-grip strength was positively correlated with nutritional status in bed-ridden elderly patients, as a result the hand-grip strength can evaluate the nutritional status.
