Abstract

Introduction/Objective

Ankylosing spondylitis (AS) is usually seen in among younger person of working age and carries a significant economic burden. It was aimed to explore the relation of work instability with fatigue, depression, and anxiety in working AS patients comparing with healthy controls.

Method

This case-control study was conducted on working 61 AS patients and 40 sex-age-matched working healthy controls. The data were collected using Visual analogue scale-pain, Bath AS Disease Activity Index, Bath AS Functional Index, Bath AS Metrology Index in patients; and Beck Depression Inventory, Beck Anxiety Inventory, Multidimensional Assessment of Fatigue, AS Work Instability Scale in all participants. Data were analyzed by SPSS, using chi-squared test, Mann–Whitney U test, Kruskal–Wallis test, Spearman correlation analysis, and multivariate linear regression analysis.

Results

Depression, fatigue, and work instability scores were significantly higher in patients than controls (p < 0.05). Clinical parameters (except spinal mobility) showed a significant worsening across the levels of work instability in patients (p < 0.05) and work instability scores were positively correlated with all clinical parameters except spinal mobility (p < 0.001). There was a weak correlation between work instability and spinal mobility (p < 0.05). Fatigue (p < 0.001), pain, and functional capacity scores (p < 0.05) were found to be influential variables on work instability scores.

Conclusion

The results of this study demonstrated that fatigue and depressive symptoms had negative effect on work instability beside pain, disease activity, and functionality in patients with AS. The recognition and improvement of fatigue and depression may lead to reduced risk of job loss in these patients.
