Remnant cholesterol inflammatory index and chronic lung disease in middle-aged and older Chinese adults: A cross-sectional analysis of the China Health and Retirement Longitudinal Study
Cross-sectional analysis reveals remnant cholesterol inflammatory index is linked to chronic lung disease in older adults, suggesting further investigation is needed.
Key Points
To assess the association between remnant cholesterol inflammatory index (RCII) and chronic lung disease (CLD) in middle-aged and older Chinese adults.
Cross-sectional analysis using data from the China Health and Retirement Longitudinal Study.
Included 7694 adults aged ≥ 45 years with complete lipid and inflammation measurements from 2011 and 2015.
Utilized multivariable logistic regression models to estimate associations between RCII and CLD.
12.6% of participants reported chronic lung disease (CLD).
Higher baseline RCII quartiles indicated increased odds of CLD: ORs of 1.18, 1.32, and 1.47 for the 2nd, 3rd, and 4th quartiles respectively (ref: lowest quartile).
Cumulative RCII was also linked to CLD with ORs of 1.24, 1.52, and 1.72 for increasing quartiles.
