Vitamin D deficiency is prevalent in rheumatoid arthritis (RA) patients and is linked to increased disease activity and reduced quality of life (QoL).
A study involving 97 RA patients showed negative correlations between vitamin D levels and disease activity scores, while higher vitamin D levels correlated with better QoL and physical activity.
The research suggests that regular physical activity may improve vitamin D levels and overall well-being in RA patients, indicating a need for further studies to understand these relationships better.
