title: The impact of rheumatoid arthritis on work capacity in Chinese patients: a cross-sectional study.
abstract: OBJECTIVE
  To evaluate the impact of RA on work capacity and identify factors related to work capacity impairment in patients with RA.
  
  
  METHODS
  A cross-sectional multicentre study was performed in 21 tertiary care hospitals across China. A consecutive sample of 846 patients with RA was recruited, of which 589 patients of working age at disease onset constituted the study population. Information on the socio-demographic, clinical, working and financial conditions of the patients was collected. Logistic regression analyses were used to identify factors associated with work capacity impairment.
  
  
  RESULTS
  The rate of work capacity impairment was 48.0% in RA patients with a mean disease duration of 60 months (interquartile range 14-134 months), including 11.7% leaving the labour force early, 33.6% working reduced hours and 2.7% changing job. Multivariable logistic regression analysis showed that reduced working hours was significantly related to current smoking [odds ratio (OR) 2.07 (95% CI 1.08, 3.97)], no insurance [OR 1.94 (95% CI 1.20, 3.12)], in manual labour [OR 2.66 (95% CI 1.68, 4.20)] and higher HAQ score [OR 2.22 (95% CI 1.36, 3.60)]. There was an association of current smoking [OR 3.75 (95% CI 1.54, 9.15)], in manual labour [OR 2.33 (95% CI 1.17, 4.64)], longer disease duration [OR 1.01 (95% CI 1.00, 1.01)] and lower BMI [OR 0.90 (95% CI 0.82, 0.99)] with leaving the labour force early.
  
  
  CONCLUSIONS
  There is a substantial impact of RA on the work capacity of patients in China. Social-demographic, disease- and work-related factors are all associated with work capacity impairment.
