Life-style activities in systemic lupus erythematosus

OBJECTIVE

We evaluated the life-style activities of outpatients with SLE and factors that reduce their social activities.

METHODS

SUBJECTS

SLE group = 60 patients, Control 1 = 30 healthy subjects and Control 2 = 30 patients with other autoimmune diseases. The Frenchay Activity Index (FAI), Zung's self-rating depression scale (SDS), and the Japanese version of the Philadelphia Geriatric Center morale scale-revised (MS) were compared between groups. Relation between FAI and age, disease duration, steroid dose, SDS, and MS were examined in the SLE group, Control 1, and Control 2.

RESULTS

Total scores by FAI was 28.1 +/-8.0 points in Control 1, whereas it was 26.5 +/- 5.8 points in Control 2 and 24.5 +/- 7.7 points in the SLE group. While there was no statistical difference between the SLE group and Control 2, the scores were significantly lower in the SLE group than in Control 1 (P < 0.05). In SLE patients, age, the duration of the disease, and the steroid dose had no correlation, but MS had a positive correlation (P < 0.05) and SDS had a negative correlation (P < 0.05). In Control 2, age, the duration of the disease, the steroid dose, MS and SDS had no correlation whereas there was significant negative relation between FAI and SDS in Control 1 (r= -0.516, P<0.005).

CONCLUSION

The significant relation between life-style activities and subjective well-being, and depression in SLE suggests that detection and treatment of mental status is important in improving the life-style activities of SLE patients.
