Endometriosis is a chronic, inflammatory disease affecting 10% (1 out of 10) of women of reproductive age. Pelvic pain is common among women with endometriosis.

Women with chronic pelvic pain conditions have elevated rates of relational stress and lower quality of life.

A cross-sectional study was conducted involving women with diagnosis of endometriosis.Patients with endometriosis and healthy women as controls are also recruited in the study.

The investigators used self-composed questionnaire for evaluating socio-demographic data and life-style factors, gynecological anamnesis, endometriosis diagnosis and further chronic conditions. Pain intensity was evaluated using Visual Analog Scale (VAS) focusing on perceived pain at present, the avarage perceived pain last month and the most intense perceived pain last month. Further measuring instruments were the Perceived Stress Scale (PSS) for evaluating stress levels among subjects, SF 36 short form health survey questionnaire for measuring health-related quality of life, Global Physical Activity Questionnaire (GPAQ) for evaluating physical activity of the subjects, Pain Catastrophizing Scale (PCS) for examining the subjects' perception of and reaction for a painful event, Pelvic Pain Impact Questionnaire (PPIQ) for evaluating the pelvic pain impact on the subjects' ability to perform physical activity, prolonged sitting, limitations in social activities, sexual activities and intimacy, Pain Self-Efficacy Questionnaire (PSEQ) for evaluating the confidence in performing different activities.

Data were analysed using IBM SPSS 28.0 and Microsoft Excel 2018 softwares and descriptive statistics, average, mean, standard deviation, two sample t-test, Pearson chi square test, Kolmogorov-Smirnov and Shapiro-Wilk test.

Dependent variables were the level of pelvic pain, physical activity, scores on the questionnairies, body mass index (BMI), independent variables were age, diagnosis of endometriosis, educational level.
