Low grip strength has been associated with an increase in depressive symptoms, independent of age group or gender, although the literature has not investigated this association among different chronic diseases. The present study aims to investigate the association of grip strength and depressive symptoms among middle-aged and older adults with different chronic diseases. A cross-section of data from the Survey of Health, Ageing, and Retirement in Europe wave 6 (collected in 2015) was analysed. Grip strength was measured by a handgrip dynamometer, and the European Depression Symptoms 12-item scale (EURO-D) was used to assess depressive symptoms. Multivariable logistic regression analysis was conducted. Those in the high strength tertile had 42% (95% confidence interval: 0.50, 0.71; p < 0.005) and 41% (95% confidence interval: 0.50, 0.70; p < 0.001) lower odds of depressive symptoms in the ‘no disease’ and in the ‘metabolic diseases’ groups of participants, respectively, compared with those in the lower strength tertile. No statistically significant relationship between grip strength and depression was observed in the ‘arthritis diseases’ group of participants. The association of grip strength with depressive symptoms must consider, besides gender and age group, the chronic conditions that an individual could have.

不同慢性病中老年人的握力与抑郁症状的关系

低握力与抑郁症状的增加有关，而与年龄组或性别无关，尽管文献尚未研究不同慢性疾病之间的这种联系。本研究旨在调查不同慢性疾病的中老年人的握力与抑郁症状之间的关系。分析了欧洲健康，老龄化和退休调查第6浪（2015年收集）的横截面数据。用握力计测量握力，用欧洲抑郁症状12项量表（EURO-D）评估抑郁症状。进行了多变量逻辑回归分析。高强度三分位数中的那些有42％（95％置信区间：0.50，0.71; p<0.005）和41％（95％置信区间：0.50，0.70; p <0.001）的参与者中``无病''组和``代谢性疾病''组的抑郁症状发生机率分别比低组低力量三分。在“关节炎疾病”组的参与者中，没有观察到握力与抑郁之间的统计学显着相关性。除了性别和年龄组外，握力与抑郁症状的关联还必须考虑个人可能患有的慢性疾病。
