AbstractPrevious studies have shown increased pain sensitivity in fertile-aged women with endometriosis in response to mechanical stimuli. As yet, population-based studies on the association of endometriosis with pain sensation and pain symptoms in late fertile age are lacking. The main objective of this population-based cohort study was to investigate whether a history of endometriosis is associated with altered pain sensation and musculoskeletal pain symptoms at age 46 years. Our data are derived from the Northern Finland Birth Cohort 1966, which contains postal questionnaire data (72% response rate) as well as clinical data assessing pressure-pain threshold and maximal pain tolerance. The study population consisted of 284 women with endometriosis and 3,390 controls. Our results showed that at age 46 women with a history of endometriosis had a 5.3% lower pressure-pain threshold and 5.1% lower maximal pain tolerance compared with controls. The most significant contributors besides endometriosis were anxiety, depression, and current smoking status. Women with endometriosis also reported an increased number of pain sites (0 pain sites, 9.6 vs 17.9%; 5–8 pain sites, 24.8 vs 19.1%, endometriosis vs controls respectively; P < .001), and their pain was more troublesome and intense. The results were adjusted for body mass index, smoking, depressive/anxiety symptoms, education, and use of hormonal contraceptives. These unique data revealed an altered pain sensation and a greater likelihood of reporting musculoskeletal pain at age 46 years among women with a history of endometriosis. The results imply that endometriosis has a long-term footprint on affected women, thus underlying the need for psychological support and medical treatment beyond fertile age. Perspective This population-based cohort study showed decreased pain threshold and maximal pain tolerance in women with endometriosis in the late fertile age of 46 years. The pain was also found to be more bothersome and intense compared with controls. see all
