This study sought to investigate the potential risk factors associated with weak and asymmetric handgrip strength (HGS) in older Chinese adults.
A total of 2702 participants aged ≥65 years from the two waves of data (2011 and 2013) from the China Health and Retirement Longitudinal Study were analyzed. The highest recorded HGS values (Method A) or the average HGS values (Method B) for the dominant hand were used to compute the HGS asymmetry (nondominant HGS/dominant HGS out of 0.9-1.1) and HGS weakness (male <28 kg, female <18 kg). Risk factors associated with the weak and asymmetric HGS were identified by logistic regression analysis.
Risk factors associated with weak and asymmetric HGS of varying severity differed between the two methods. Both methods identified age and illiteracy as risk factors for weak HGS with 10%-20% asymmetry. Method A also identified speech impediment, stroke, and sleep duration as additional risk factors. Similarly, both methods identified age, illiteracy, primary school education and below, diabetes, and stroke as risk factors for weak HGS and asymmetry over 30.1%. Method B additionally identified a history of falls as a risk factor. However, apart from age, the risk factors for weak HGS with 20.1%-30% asymmetry differed between the two methods-Method A identified kidney disease, while Method B identified illiteracy and asthma.
The results revealed that risk factors associated with the abnormal HGS in older adults varied based on the methods used to define these conditions.
本研究旨在探讨与老年中国人握力弱和不对称相关的潜在危险因素。
对来自中国健康与养老追踪调查（CHARLS）2011 年和 2013 年两轮数据的 2702 名年龄≥65 岁的参与者进行分析。使用记录的最高握力值（方法 A）或惯用手的平均握力值（方法 B）计算握力不对称性（非优势手握力/优势手握力的 0.9-1.1 倍）和握力减弱（男性<28kg，女性<18kg）。采用 logistic 回归分析确定与弱握力和不对称握力相关的危险因素。
两种方法确定的与握力强弱和不对称程度不同的危险因素存在差异。两种方法均发现年龄和文盲是握力弱（不对称性 10%-20%）的危险因素。方法 A 还发现言语障碍、中风和睡眠时长是额外的危险因素。同样，两种方法均发现年龄、文盲、小学及以下教育程度、糖尿病和中风是握力弱和不对称性超过 30.1%的危险因素。方法 B 还发现有跌倒史是一个危险因素。然而，除了年龄，握力弱（不对称性 20.1%-30%）的危险因素在两种方法之间存在差异——方法 A 发现肾病，而方法 B 发现文盲和哮喘。
结果表明，与老年人异常握力相关的危险因素因定义这些情况的方法而异。
