The Impact of Endometriosis on the Quality of Life and the Incidence of Depression-A Cohort Study

The objective was to evaluate the quality of life and the incidence of depression among women suffering from endometriosis. Afterwards, the dependency between pelvic pain, its severity and stages of endometriosis were analyzed. The study protocol included women of reproductive ages with confirmed endometriosis. The stage of disease was conferred according to the ASRM (American Society of Reproductive Medicine) classification. Women fulfilled two questionnaires: "WERF EPHect Clinical Questionnaire" and self-prepared survey about fertility disorders. The study group comprised of 246 respondents. A total of 77.2% of women were symptomatic. The most common complaints were chronic pelvic pain (CPP, 71.1%), dysmenorrhea (69.0%) and dyspareunia (45.2%). Intensity of pain was independent from the stage of endometriosis. The incidence of infertility and the time to conceive increased with the stage of disease (stage 1-52.8%, 3.4 years; stage 2-66.7%, 4.1 years; stage 3-61.3%, 3.7 years; stage 4-96%, 6.1years; p = 0.02 and 0.03, respectively). The prevalence of depression was positively correlated with the beginning of dyspareunia (14.5 vs. 19.6 years old., p = 0.002). CPP (OR(odds ratio) = 3.8, 95% CI 1.2-12.8, p = 0.04) and painful defecation (OR = 7.7, 95% CI 1.4-42.3, p = 0.01) increased the risk of depression. Symptoms related to endometriosis and severity of pain correlate with the prevalence of depression. Stage of endometriosis is significantly related to the prevalence of infertility.
