Abstract [en]

OBJECTIVE: To compare women and men regarding course of disease activity and disability over 8 years from diagnosis of recent onset rheumatoid arthritis (RA). PATIENTS AND METHODS: 149 patients were followed for 8 years from RA diagnosis (1996-98) regarding 28-joint count disease activity score (DAS28), pain (visual analogue scale, VAS), grip force, Grip Ability Test (GAT), Signals of Functional Impairment (SOFI hand, upper/lower extremity), walking speed, activity limitation (Health Assessment Questionnaire, HAQ) and prescribed disease-modifying anti-rheumatic drugs (DMARDs). RESULTS: Disease activity pattern over time was similar in women and men, showing improvement during the first year and thereafter a stable situation during 6 years. However, at the 7- and 8-year follow-ups deterioration was seen with a less favourable course in women. HAQ did not differ between sexes at diagnosis, but at all follow-ups women had significantly higher scores than men. Women also had lower grip force and lower walking speed, but higher upper extremity mobility. DMARD prescription was similar for both sexes. Over eight years, disease duration, sex, biologics, grip force, SOFI-hand and pain intensity together explained 43% of the variation in DAS, while grip force, SOFI-lower, GAT and pain intensity could together explain 55% of variations in HAQ. CONCLUSIONS: Disease activity was fairly well managed, but disability gradually deteriorated. Despite similar medication, women had more disability than men. The discrepancy between disease activity and disability indicates unmet needs for multi-professional interventions to prevent progressing disability and patients at risk for disability need to be identified early in the process. © 2012 by the American College of Rheumatology.
