This investigation sought to determine the associations between handgrip strength (HGS) asymmetries and limitations in individual activities of daily living (ADL). The analytic sample included 18,468 participants from the 2006 to 2016 waves of the Health and Retirement Study. Those with HGS >10% stronger on either hand had any HGS asymmetry. Individuals with HGS >10% stronger on their dominant or non-dominant hand had dominant or non-dominant HGS asymmetry, respectively. ADL abilities were self-reported. Those with any HGS asymmetry had 1.21 (95% confidence interval [CI] = [1.01-1.46]) greater odds for a toileting limitation and 1.25 (CI = [1.03-1.52]) greater odds for a transferring limitation. Individuals with dominant HGS asymmetry had 1.24 (CI = [1.01-1.53]) greater odds for a transferring limitation. Those with non-dominant HGS asymmetry had 1.39 (CI = [1.01-1.93]) and 1.44 (CI = [1.05-1.96]) greater odds for a bathing and toileting limitation, respectively. HGS asymmetries could help to identify future limitations in specific ADLs.
本研究旨在探讨握力（HGS）不对称与日常生活活动（ADL）受限之间的关联。分析样本包括来自 2006 年至 2016 年健康与退休研究的 18468 名参与者。那些单手 HGS 强 10%以上的人存在任何 HGS 不对称。单手或非优势手 HGS 强 10%以上的人分别存在优势或非优势 HGS 不对称。ADL 能力是自我报告的。任何 HGS 不对称的人如厕受限的几率增加 1.21 倍（95%置信区间 [CI] = [1.01-1.46]），转移受限的几率增加 1.25 倍（CI = [1.03-1.52]）。优势 HGS 不对称的人转移受限的几率增加 1.24 倍（CI = [1.01-1.53]）。非优势 HGS 不对称的人洗澡和如厕受限的几率分别增加 1.39 倍（CI = [1.01-1.93]）和 1.44 倍（CI = [1.05-1.96]）。HGS 不对称性可能有助于识别未来特定 ADL 的受限情况。
