Abstract

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.

Keywords: Korea; dynapenia; older adults; smoking; smoking cessation.
