Health-related quality of life and its related factors in patients with systemic lupus erythematosus in southwest Iran: a cross-sectional study

BackgroundQuality of life (QoL) is an important measure in health assessment. It is impacted by unclear factors in Systemic Lupus Erythematosus (SLE) patients. The study aimed to investigate the factors related to QoL in SLE patients.MethodsThis cross-sectional study was performed on 140 (136 women and four men) Iranian SLE patients of Hafiz Hospital from June 2019 to August 2020. The Lupus Erythematosus Quality of Life Questionnaire (LEQoL) was used to evaluate the quality of life. The patients were evaluated with this questionnaire for four weeks in eight dimensions health, emotional health, body image, pain, planning, intimate relationships, and the burden of others. Related factors of LEQoL were evaluated using multivariable linear regression.ResultsThe mean age was 34.09(8.96) years. The total mean QoL Score was 65.5 & PLUSMN; 22.4. The multivariable analysis showed that duration of disease (& beta;:-1.12, 95% CI:-1.44 to -0.79, P:0.001), physical activity(& beta;:-12.99, 95% CI:-19.2 to -6.13, P:0.001), kidney involvement (& beta;:-9.2, 95% CI:-16.61 to -2.79, P:0.03) and skin involvement(& beta;:-8.7, 95% CI:-17.2 to -0.2, P:0.031) were significantly related to the total mean QOL score of SLE patients.ConclusionThe QoL of Iranian patients with SLE was low. Age and gender can be related to the decrease in the QoL of patients with SLE. Increasing the disease duration, physical activity, kidney involvement, and skin involvement can be related to the decrease in the QOL of Iranian patients with SLE.
