This paper used a case-control design to investigate factors associated with endometriosis and potential differences between Chinese and UK patients. The authors recruited 387 endometriosis cases and 199 non-cases from Oxford (John Radcliffe Hospital) and 101 cases and 50 non-cases from Guangzhou First Affiliated Hospital of Guangzhou University of Chinese Medicine, collecting standardized data via the WERF EPHect questionnaire covering anthropometrics, menstrual and reproductive history, prior surgeries, and clinical context. Multivariable logistic regression found that in UK patients, higher BMI, surgery for dysmenorrhea, history of pregnancy, number of previous endometriosis surgeries, and work status were associated with endometriosis, whereas in Chinese patients dysmenorrhea history was associated. The study’s limitation, as reflected by the cross-sectional retrospective case-control approach and reliance on questionnaire-reported exposures, is that it cannot establish causality; overall, pain-related history appears central but risk factor profiles may differ across settings. This paper is centrally about endometriosis — it compares associated risk factors for endometriosis between China and the UK.

Abstract

OBJECTIVE: To explore the differences in the factors associated with endometriosis between Chinese and British patients. METHODS: This case-control study was conducted in 387 patients with endometriosis and 199 non-endometriosis patients admitted to John Radcliffe Hospital (Oxford, UK) and in 101 patients with endometriosis and 50 non-endometriosis patients admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine. The clinical data including height, weight, body mass index, marital status, employment, menstruation, fertility, and operation reasons were collected via a standardized WERF EPHect questionnaire. RESULTS: < 0.05). CONCLUSION: Dysmenorrhea may be the most important common factor associated with endometriosis in China and the UK, but the other factors contributing to endometriosis may differ between these two countries.
