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.
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.
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).
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.
众所周知，肌肉力量在老年人健康中起着重要作用。老年人吸烟的健康负担仍然很大。我们调查了韩国老年长期吸烟者戒烟与肌肉减少症之间的关联。
本研究是对2016 - 2019年韩国国家健康与营养检查调查（KNHANES）的横断面数据进行的二次数据集分析。我们纳入了1450名65 - 79岁的参与者，排除了从不吸烟的人。根据2019年亚洲肌肉减少症工作组的标准，肌肉减少症定义为男性握力<28千克，女性握力<18千克。多变量逻辑回归分析评估了戒烟与肌肉减少症之间的关联。
与当前吸烟者相比，既往吸烟者发生肌肉减少症的调整优势比（AOR）为0.66（95%置信区间：0.44 - 0.99）。戒烟时间≤10年、10 - 20年、20 - 30年和>30年的AOR分别为0.67（95%置信区间：0.39 - 1.16）、0.61（95%置信区间：0.36 - 1.03）、0.65（95%置信区间：0.37 - 1.14）和0.52（95%置信区间：0.25 - 1.06）。自戒烟以来，肌肉减少症的AOR随时间显著降低（趋势p值 = 0.043）。
我们的研究结果表明，戒烟可以降低老年长期吸烟者发生肌肉减少症的可能性，且戒烟时间越长，这种可能性降低的趋势越明显。
