One of the most used methods to assess pain is the visual analogue scale (VAS). The aim of the present research was to study the pain experienced by patients who referred to our unit for endometriosis, using the VAS to understand the variables that could influence it.<\/jats:p><jats:p>\n            Methods\u2003We have conducted a prospective study from February 2012 to December 2016, enrolling 388 patients who referred to a university hospital, in Florence, Italy. We have included in the present study patients during their follow-up for endometriosis; we have also included patients who underwent surgery with a histological diagnosis of endometriosis. We have collected sociodemographic and clinical information regarding age, body mass index (BMI), smoking habit, number of pregnancies, and endometriosis staging. Finally, we have administered the VAS for several symptoms.<\/jats:p><jats:p>\n            Results\u2003Dysmenorrhea was the symptom associated with the highest perception of pain (mean VAS score of 5.76). The logistic regression showed that the stage of endometriosis could influence the pain associated to constipation and to dysuria. The linear regression showed that age could influence the pain associated to constipation, to dyspareunia, and to dysmenorrhea. A positive correlation was found between dysmenorrhea and chronic pelvic pain (CPP), between dysmenorrhea and dyspareunia, and between constipation and dysuria.<\/jats:p><jats:p>\n            Conclusion\u2003Using a validated method, the VAS, we have studied the pain experienced by a group of patients with a history of endometriosis and observed that smoking habit and BMI did not influence the VAS scores, and that dysmenorrhea was associated with the highest perception of pain.<\/jats:p>","DOI":"10.1055\/s-0039-1679879","type":"journal-article","created":{"date-parts":[[2019,4,16]],"date-time":"2019-04-16T23:11:05Z","timestamp":1555456265000},"page":"170-175","source":"Crossref","is-referenced-by-count":33,"title":["Variables
