Background
We have demonstrated in a previous systematic
review that Rheumatoid Arthritis (RA) impacts on all
aspects of Quality of Life (QoL), with detrimental
effects observed in all 8 health domains of the
Medical Outcomes Study 36-item Short-Form Health
Survey (SF-36). The recent shift in the paradigm of
RA management towards early combination therapies
may have altered the impact of RA on QoL. We
therefore performed an updated systematic review
examining the impact of RA on QoL measured using
the SF-36, and are the first to present meta-analysed
data showing QoL in RA.
Methods
Medline and Embase were searched using the terms
Rheumatoid Arthritis or RA and Quality of Life or SF-36.
Observational studies were included that reported mean
and standard deviation scores for all SF-36 domains in
RA patients. Domain scores across studies were
combined within a meta-analysis to provide summary
scores for each domain. The clinical and psychosocial

Reduced physical QoL was associated with increased
disease activity, physical disability, pain and fatigue;
reduced mental QoL was generally associated with
increased disease activity, pain, fatigue, and
increasing age.
Conclusions
RA impairs QoL, particularly the physical components
of the SF-36. QoL is associated with several
