This study is a cross-sectional study carried out on 250 already diagnosed rheumatoid arthritis patients who attended Baghdad Teaching Hospital/Medical City/Rheumatology department.

The results of the current study showed that rheumatoid arthritis has a significant effect on the quality of life of patients. The mean of the total quality of life score was 46.9 ± 9.7.  Older age was associated with the reduced psychological and environmental score. Female patients had high physical and psychological score compared to male patients. Higher education levels worked patients directly predict the elevated quality of life score.
