Association between Sarcopenia and Chronic Lung Diseases among Older Chinese: Findings from the China Health and Retirement Longitudinal Study

Abstract

To analyze the association between sarcopenia and chronic lung diseases among older Chinese,we obtainted the data from China Health and Retirement Longitudinal Study (CHARLS) in 2015. Sarcopenia were classified according to the Asian Working Group for Sarcopenia (AWGS) 2019 criteria. Chronic lung diseases were previously diagnosed by physicians. The logistic regression model was used to analyze the association between sarcopenia and chronic lung diseases. A total of 5093 participants aged over 60 were included. The prevalence of chronic lung diseases in total populations, non-sarcopenia, possible sarcopenia, sarcopenia individuals were 13.9% (710/5093), 12.3% (353/2875), 14.8% (253/1705), and 20.3% (104/513), respectively. Both possible sarcopenia (OR: 1.30; 95% CI: 1.07-1.57, P = 0.008) and sarcopenia (OR: 1.36; 95% CI: 1.00-1.86, P = 0.051) were significantly associated with the prevalence of chronic lung diseases. In conclusion, possible sarcopenia and sarcopenia are independent risk factors for the prevalence of chronic lung diseases among older Chinese.
