INTRODUCTION Muscle strength is known to play an important role in the health of older adults. The health burden of cigarette smoking among older adults remains significant. We investigated the association between smoking cessation and dynapenia among older lifetime smokers in Korea. METHODS This study is a secondary dataset analysis of cross-sectional data from theKorea National Health and Nutrition Examination Survey (KNHANES) 2016- 2019. We included 1450 participants aged 65-79 years, excluding those who had never smoked. Dynapenia was defined as grip strength <28 kg for men and <18 kg for women based on the Asian Working Group for Sarcopenia 2019 criteria. Multivariable logistic regression analysis evaluated the association between smoking cessation and dynapenia. RESULTS Compared with current smokers, the adjusted odds ratio (AOR) of dynapenia in former smokers was 0.66 (95% CI: 0.44-0.99). The AORs for smoking cessation periods of ≤10 years, 10-20 years, 20-30 years, and >30 years were 0.67 (95% CI: 0.39-1.16), 0.61 (95% CI: 0.36-1.03), 0.65 (95% CI: 0.37-1.14), and 0.52 (95% CI: 0.25-1.06), respectively. The AOR for dynapenia significantly decreased with the years since smoking cessation (p for trend=0.043). CONCLUSIONS Our findings suggest that smoking cessation can reduce the likelihood of dynapenia among older lifetime smokers, with a decreasing likelihood trend associated with longer cessation periods.

韩国老年吸烟者戒烟与缺乏症的关联。


简介 众所周知，肌肉力量在老年人的健康中发挥着重要作用。老年人吸烟的健康负担仍然很重。我们调查了韩国老年吸烟者戒烟与缺乏症之间的关系。方法 本研究是对 2016-2019 年韩国国家健康和营养检查调查 (KNHANES) 横截面数据的二次数据集分析。我们纳入了 1450 名年龄在 65-79 岁的参与者，不包括从未吸烟的参与者。根据亚洲肌少症工作组 2019 年的标准，Dynapenia 的定义为男性握力<28 kg，女性握力<18 kg。多变量逻辑回归分析评估了戒烟与缺乏症之间的关联。结果 与当前吸烟者相比，前吸烟者无症状的调整优势比（AOR）为0.66（95% CI：0.44-0.99）。戒烟期限≤10年、10-20年、20-30年和>30年的AOR分别为0.67（95% CI：0.39-1.16）、0.61（95% CI：0.36-1.03）、0.65（ 95% CI：0.37-1.14）和 0.52（95% CI：0.25-1.06）。随着戒烟后年数的增加，无症状的 AOR 显着下降（趋势 p=0.043）。结论 我们的研究结果表明，戒烟可以降低老年吸烟者发生无性缺乏的可能性，且戒烟时间越长，可能性就越低。
