ObjectivesPatients with systemic lupus erythematosus (SLE) may experience body image disorders, which can adversely affect their physical and mental health. We aimed to assess the body-image-related quality of life of patients with SLE, explore the influencing factors and determine the potential predictors of body image disturbance (BID) in these patients.DesignCross-sectional study.SettingThe department of rheumatology and immunology in Nantong.ParticipantsA convenience sample of 230 patients with SLE.InterventionsThe study survey included an assessment of demographic information and evaluations using the Body Image Disturbance questionnaire (BIDQ), Hospital Anxiety and Depression Scale, Multidimensional Fatigue Inventory-20 and Body Image Quality of Life Inventory (BIQLI).Primary and secondary outcome measuresBID scores and their possible predictors. Data were analysed using descriptive statistics, correlational analysis and stepwise multiple linear regression analysis.ResultsThe mean BIDQ score and the mean scores for anxiety, depression and fatigue were 23.04 (SD, SD=11.90), 6.94 (SD=4.53), 6.49 (SD=4.51) and 54.21 (SD=11.63), respectively. The mean BIQLI score was 0.31 (SD=16.59). The findings revealed significant correlations with education level, comorbidities, SLE Disease Activity Index (SLEDAI), anxiety, depression, fatigue and BIQLI. Fatigue, depression, presence of comorbidities and SLEDAI were predictors of worsening BID (p<0.05).ConclusionIn our study, the relationship between BIDQ and anxiety, depression, and fatigue was analysed, and predictors of BID were defined. When formulating interventional measures, the patient's condition should be evaluated, and effective interventions should be implemented to improve the patient's body image and ultimately improve the patient's quality of life.
