They had kept taking the LDA or started treatmentduring the study period and kept taking LDA during the whole period of observation. Of these, 119 patients (87 males, 32 females) were diagnosed as having LDA-associated peptic ulcer. We examined the clinical factors associated with LDA-associated peptic ulcer in both sexes.RESULTS: A history of peptic ulcer was found to be the risk factor for LDA-associated peptic ulcer common to both sexes. In female patients, age greater than 70 years (prevalence ORs 8.441, 95% CI: 1.797-33.649, P = 0.0069) was found to be another significant risk fac-tor, and the time to diagnosis as having LDA-associat-ed peptic ulcer by endoscopy was significantly shorter than that in the male patients (P = 0.0050). CONCLUSION: We demonstrated gender differences about the clinical features and risk factors of LDA-asso-ciated peptic ulcer. Special attention should be paid to aged female patients taking LDA.展开更多
