Distinct multi-trajectories over 15-year follow-up for five different self-reported pain-related health outcome measures (Health Assessment Questionnaire Disability Index, visual analogue scores for pain, arthritis, global health and the Assessment of Quality of Life utility index) were identified using latent variable discrete mixture modelling. Random effects models were used to determine associations with medication use and biologic therapy modification during follow-up.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Four, approximately equally sized, pain\/health status groups were identified, ranging from \u2018better\u2019 to \u2018poorer\u2019, within which changes over time were relatively small. Important determinants of those with poorer pain\/health status included female gender, obesity, smoking, socioeconomic indicators and comorbidities. While biologic therapy use was similar between groups during follow-up, biologic therapy modifications (p<jats:sub>linear<\/jats:sub>&lt;0.001) and greater tendency of non-tumour necrosis factor inhibitor use (p<jats:sub>linear<\/jats:sub>&lt;0.001) were observed in those with poorer pain\/health status.
