Children with onset 1997\u20132000 were part of the Nordic JIA cohort. Controls were age- and sex-matched. In 2015\u20132017, study visits with investigator-blinded quantitative sensory testing (QST) comprising cold and warm detection thresholds (CDT\/WDT), cold and heat pain thresholds (CPT\/HPT), pressure pain threshold (PPT), and a suprathreshold heat pain test were performed. We constructed separate multilevel models for each variable of detection and pain thresholds with interaction between groups and site adjusted for the effect of age and sex.<\/jats:p>\n              <\/jats:sec>\n              <jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Among 96 young adults with JIA, 71% were female, median age was 22.7\u2009years, disease duration was 16.1\u2009years, and 47% had oligoarticular disease. Among 109 controls, 71% were female, and\u00a0median age was\u00a023.5\u2009years. Participants with JIA had lower pressure pain thresholds (PPTs) (95% CI) compared to controls, upper limb 888 (846,930) versus 1029 (999,1059) kPa and lower limb 702 (670,734) versus 760 (726,794) kPa. Participants with inactive disease had the lowest PPTs and cold pain thresholds (CPTs), compared to those in remission off medication and those with active disease. Minor differences were found regarding CDT\/WDT and CPT\/HPT in JIA compared to controls. The median (IQR) temperature needed to evoke pain = 6 on a 0\u201310 numeric rating scale (NRS) in the suprathreshold heat pain tests were lower in JIA than in controls (46\u2009\u00b0C (45\u201347\u2009\u00b0C) versus 47\u2009\u00b0C (46\u201348\u2009\u00b0C)).
