Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease with treatment manifestations that can cause changes in appearance, including skin rashes, alopecia, vitiligo, and scars. SLE has been shown to adversely impact body image outcomes, and previous research has identified that greater disease activity is associated with worse body image outcomes which, in turn, are associated with greater depressive symptoms. For patients with SLE who also experience significant pain, poor body image outcomes may further compromise wellbeing and lead to greater depressive symptoms. The role of pain in body image has not been explored in SLE. Thus, the present study examined whether body image (specifically, body image-related quality of life) serves as a mediator of the relationship between pain and depressive symptoms among patients with SLE.
Multiple mediation analysis was used to examine the hypothesis that body image-related quality of life mediates the relationship between pain and depressive symptoms in a sample of patients with SLE ( = 135) from an urban region in Los Angeles, California.
The sample was predominately female (92.6%) with a mean disease duration of approximately 17 years. Approximately one-quarter of the sample had elevated depressive symptoms. Body image-related quality of life was a significant mediator in the relationship between pain and depressive symptoms. The model accounted for 51% of the total variance in depressive symptoms ( = 0.51).
This cross-sectional study suggested that body image-related quality of life may mediate the effects of pain on depressive symptoms among patients with SLE.
系统性红斑狼疮(SLE)是一种多系统自身免疫性疾病,其治疗表现可能导致外观改变,包括皮疹、脱发、白癜风和疤痕。SLE 已被证明会对身体意象结果产生不利影响,先前的研究已经确定,更大的疾病活动与更差的身体意象结果相关,而后者又与更严重的抑郁症状相关。对于同时经历严重疼痛的 SLE 患者,较差的身体意象结果可能进一步损害幸福感,并导致更严重的抑郁症状。SLE 中疼痛对身体意象的影响尚未得到探索。因此,本研究探讨了身体意象(特别是与身体意象相关的生活质量)是否作为 SLE 患者疼痛和抑郁症状之间关系的中介。
使用多重中介分析来检验假设,即身体意象相关的生活质量在加利福尼亚州洛杉矶市区的 SLE 患者(n=135)中,在疼痛和抑郁症状之间的关系中起到中介作用。
该样本主要为女性(92.6%),平均患病时间约为 17 年。大约四分之一的样本有明显的抑郁症状。身体意象相关的生活质量是疼痛和抑郁症状之间关系的重要中介。该模型解释了抑郁症状总方差的 51%(β=0.51)。
这项横断面研究表明,身体意象相关的生活质量可能在 SLE 患者的疼痛对抑郁症状的影响中起到中介作用。
