Abstract

Observational studies suggest a comorbid link between asthma and endometriosis, but the evidence remains limited and inconsistent. This study presents a meta-analysis examining this association. A comprehensive search of literature databases was conducted through August 2024. Prevalence rates and odds ratios (ORs) were calculated to assess the relationship between asthma and endometriosis. For the prevalence analysis, sixteen studies, including 54,856 endometriosis cases and 300,613 controls, were included. The analysis yielded a prevalence of asthma in endometriosis patients of 14.9% (95% CI [10.3, 19.6], p < 0.001), with high heterogeneity (I2 = 99.9%). In the control group, asthma prevalence was 9.1% (95% CI [6.5, 11.6], p < 0.001, I2 = 99.9%). For the odds ratio (OR) analysis, twelve studies, including 295,845 endometriosis cases and 28,030,081 controls, were included. The meta-analysis demonstrated a significant association between asthma and endometriosis with an OR of 1.59 (95% CI [1.22, 2.07], p = 0.0007, I2 = 100%). Subgroup analyses stratified by study region and study type were also conducted. This meta-analysis suggests a significant association between asthma and endometriosis, indicating that common factors underlying these chronic inflammatory diseases may contribute to this comorbidity. The findings support the biological plausibility of this association.
