Objective:
To identify the possible risk factors of endometriosis in Chengdu.
Methods:
A hospital-based pair matched case-control study was carried out in 100 pair of female patients with endometriosis and their controls. The data were analysed by univariate analysis, multi-variate conditional logistic regression and ANOVA.
Results:
Univariate analysis showed that the positive response rates for "high educational level, history of ectopic pregnancy, short menstrual cycle, menorrhagia, dysmenorrhea, not warmly dressed during menses, depression, history of coitus during menstruation or puerperium and heavy pungent food" in the endometriosis group were much higher than those in the control group (P < 0.05). The multivariate analysis confirmed that the risk factors associated with endometriosis were menorrhagia, not warmly dressed during menses, depression during menstruation, heavy pungent food, and history of ectopic pregnancy (OR = 0.388, 3.066, 4.292, 2.742, 3.612, respectively).
Conclusion:
The above findings suggest that endometriosis may be associated with menorrhagia, negligence in menstrual hygiene, and certain behavioral and psychological factors.
