However, in patients with juvenile idiopathic arthritis (JIA) AP has scantily been studied. Among other reasons, gastrointestinal symptoms may present as side effects due to the medical treatment of JIA. The aim of the study was to explore the frequency of AP and its relationship to disease components and health-related quality of life (HRQoL) among young adults with JIA. Methods This study included a cohort of 97 Finnish patients belonging to the population-based Nordic JIA cohort at their 17-year follow-up study visit. Mean age of the patients was 23 years. AP, functional status, fatigue, HRQoL, disease characteristics of JIA, and comorbidities were evaluated. AP was classified into three categories according to frequency: (1) never, (2) seldom (one to three times a month) and (3) frequent (at least once a week). Results About 48 (50%) young adults with JIA reported AP. Seldom AP was reported by 37 (38%), and frequent AP by 11 (11%) patients. AP was significantly associated with fatigue, female gender, functional status and arthritis-related pain. Patients having frequent AP reported lower HRQoL. AP was associated with the use of methotrexate and sulfasalazine, but not with nonsteroidal anti-inflammatory drugs (NSAIDs). Conclusion AP is an important complaint in young adults with JIA and is associated with fatigue, female gender, methotrexate and sulfasalazine use. Patients with JIA reporting frequent AP with lower functional status and higher arthritis-related pain values have lower HRQoL.6engcc_by_nc_ndinfo:eu-repo/semantics/openAccessAbdominal painjuvenile idiopathic arthritisoutcome measureshealth-related quality of lifesynthetic disease modifying antirheumatic drugsyoung adultsQUALITY-OF-LIFEINFLAMMATORY-BOWEL-DISEASEFATIGUE SEVERITY SCALERHEUMATOID-ARTHRITISPOPULATIONCHILDRENRISKEPIDEMIOLOGYASSOCIATIONSPREVALENCEGeneral medicine, internal medicine and other clinical medicineArticleopenAccess9488f93b-d015-444c-b417-10c0faf98688000793914900001
