AbstractWith China's aging population, the incidence of eye diseases is increasing, leading to urgent concerns about visual impairment and blindness. The cause-and-effect relationship between asthma and eye diseases in the Chinese population remains unclear. This study aimed to investigate the link between asthma and eye-related diseases, including cataracts and glaucoma, among Chinese adults. This study utilized data from the 4th wave of the China Health and Retirement Longitudinal Survey conducted in 2018, involving 19,816 Chinese participants. We first described baseline characteristics, then constructed 5 logistic regression models to study the relationship between asthma and eye diseases in the Chinese context. Additionally, subgroup analyses were performed with selected variables. Across 5 models adjusting for covariates, we found that asthma was significantly associated with cataracts (odds ratios [95% confidence intervals]: 1.36 [1.01-1.79], P = .034) and glaucoma (odds ratios [95% confidence intervals]: 1.92 [1.46-2.49], P < .001). Subgroup analyses revealed that Chinese women, former smokers, or drinkers were at higher risk of developing cataracts (all P < .001), while those aged ≤ 60 years were at higher risk of developing glaucoma (P < .001). Our study provides possible observational evidence linking asthma to cataracts, glaucoma, and visual impairment in the Chinese population. These findings are crucial for disease prevention strategies in China's healthcare system.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
