摘要: OBJECTIVE: To evaluate the association of demographic, disease, workplace, social, and household factors with ability patients rheumatoid arthritis (RA) to remain employed over time. METHODS: Four hundred seventy-two RA recruited from a national sample rheumatology practices were followed. Patients interviewed once year by telephone for 9 years patients9 physicians provided data on clinical aspects such as disease stage, joint deformity, flares. A proportional hazards survival model based stepwise variable selection was developed investigate between continuance work period work, attitudinal, social support variables. RESULTS: In univariate analysis, significant associated longer being younger, self-employed, having higher prestige occupation, working more hours per week, education level, missing fewer days during baseline year. The final multivariate included age, type occupation number missed time varying co-variate. CONCLUSION: Ability study strongly characteristics, lost than factors. underlying mechanisms related occupational predictor should be investigated in order develop interventions reduce risk disability.
