Evaluation of the risk factors related to dysfunctional uterine bleeding in peri-menopausal women in Sanandaj

Dysfunctional uterine bleeding (DUB) is one of the common problems in peri-menopausal women that can affect their physical، emotional and social conditions. In addition DUB is one of the main causes of hysterectomy. The aim of this study was to investigate risk factors associated with DUB in peri-menopausal women in Sanandaj. This case–control study included 62 women with DUB (case group) and 124 women without DUB (control group). We used a questionnaire consisted of different items which was completed for every subject after clinical interview. Using SPSS software، data analysis was performed by chi-square، Fisher exact test and logistic regression. DUB showed significant relationships with type of delivery (p=0. 015) and age (p=0. 045). DUB had no significant relationship with diabetes (p=0. 095)، hypertension (p=0. 917) and type of contraceptive methods (p=0. 906). Analysis by logistic regression revealed that women over 50 years of age and women with history of Cesarean section (C/S) had a respective risk of 2. 284 (p=0. 021) and 2. 493 (p=0. 009) times greater to develop DUB than women without these factors. The age over 50 years and C/S was suggested as risk factors which can be related to DUB. Attention to the advantages of vaginal delivery and complications of C/S is necessary and reduction of C/S rate can be effective in decreasing the incidence of DUB.
