INTRODUCTION: Fatigue is a common, disabling, and poorly understood aspect of Rheumatoid arthritis (RA) treatment. Better understanding of fatigue is required for holistic treatment of RA. The present study was conducted to evaluate factors (disease activity, pain, sleep quality, and vitamin D) contributing to fatigue in RA.
METHOD: A cross-sectional study was conducted on 204 patients of RA. Fatigue was measured using CFQ-11 scale, pain and sleep impairment were assessed on visual analogue scale, disease activity by DAS 28 ESR, and vitamin D levels by enzyme chemiluminescence immunoassay. Univariate and multivariate binary logistic regression analyses were done to study association.
RESULTS: Mean age of study subjects was 51±11.63 years with majority (89.7%) being females and mean duration of RA was 8.54 years. Prevalence of fatigue was 66.2% (CFQ-11 score >4/11). Deficiency of vitamin D was found in 12.3% subjects. Mean sleep impairment and pain score on VAS were 32.60±21.53 and 26.37±21.65 respectively. Univariate analysis revealed that CFQ-11 fatigue score was independently associated with disease activity, pain, sleep, and vitamin D deficiency. Further Multivariate binary logistic regression analysis showed strongest association of vitamin D deficiency with fatigue (OR of 6.38 with 95% confidence interval of 1.58, 25.71). Disease activity (OR - 1.714, 95% CI- 1.14, 2.55) and sleep impairment (OR - 1.038, 95% CI- 1.005, 1.071) have also been found to be significantly associated with fatigue.
CONCLUSION: Fatigue in RA is multifactorial, and it is mediated by disease-related factors (disease activity, sleep impairment) and non-disease-related factors (vitamin D deficiency).
