We investigated the association between working status changes and hand-grip strength (HGS) among middle-aged and older Korean adults using data from the 2006-2018 Korean Longitudinal Study of Aging. After excluding those with less than normal HGS in the baseline year, newly added panels, and missing values, 3843 participants (2106 men; 1737 women) were finally included. After adjusting for potential confounders, we used a 2-year lagged multivariable generalized estimating equation model to examine this association longitudinally. Men who quit working or who continued to be non-working were more likely to have lower HGS than those who continued to work (working → non-working, adjusted odds ratio [OR]: 1.47, 95% confidence interval [CI] 1.26-1.70; non-working → non-working, adjusted OR: 1.52, 95% CI 1.34-1.72). Compared to women who continued to work, the other three groups showed high ORs with low HGS (working → non-working, adjusted OR: 1.19, 95% CI 1.01-1.40; non-working → working, adjusted OR: 1.18, 95% CI 0.98-1.42; non-working → non-working, adjusted OR: 1.38, 95% CI 1.22-1.56). Middle-aged and older adults whose working status changed to non-working were at higher risk of reduced HGS than others and required muscular strength training interventions to improve HGS and prevent sarcopenia.
我们使用 2006-2018 年韩国老龄化纵向研究的数据，调查了中年和老年韩国成年人工作状态变化与握力（HGS）之间的关联。在排除了基线年度、新加入的面板和缺失值中 HGS 低于正常值的人后，最终纳入了 3843 名参与者（2106 名男性；1737 名女性）。在调整了潜在混杂因素后，我们使用 2 年滞后多变量广义估计方程模型对这种关联进行了纵向检查。与继续工作的人相比，失业或继续失业的男性更有可能握力较低（工作→失业，调整后的优势比[OR]：1.47，95%置信区间[CI]：1.26-1.70；失业→失业，调整后的 OR：1.52，95% CI：1.34-1.72）。与继续工作的女性相比，其他三组握力较低的优势比均较高（工作→失业，调整后的 OR：1.19，95% CI：1.01-1.40；失业→工作，调整后的 OR：1.18，95% CI：0.98-1.42；失业→失业，调整后的 OR：1.38，95% CI：1.22-1.56）。工作状态变为非工作状态的中年和老年人握力下降的风险较高，需要进行肌肉力量训练干预，以提高握力，预防肌肉减少症。
