Association Between Body Image Dissatisfaction and Weight Loss Among Patients With Advanced Cancer and Their Caregivers: A Preliminary Report

Context. No prospective studies have dealt with the impact of cachexia-related weight loss on patients' body image as well as the impact of patients' body image changes on the level of patient and family distress. Objectives. Our aim was to examine associations between body mass index (BMI), weight loss, symptom distress, and body image for patients with advanced cancer and their caregivers. Methods. Outpatients with advanced cancer and different levels of BMI, along with their caregivers, were recruited. Patient assessments included BMI, precancer weight, Body Image Scale (BIS; 0-30), Edmonton Symptom Assessment System (ESAS), Hospital Anxiety and Depression Scale(HADS), and sexual interest and enjoyment as measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck Cancer Module 35. Caregivers were asked to assess the patient's body image, using the BIS; rate their own quality of life, using the Caregiver Quality of Life Index-Cancer; and rate their overall distress and distress regarding the patient's weight, using the Distress Thermometer (DT). Results. We included 81 patients and 30 caregivers. Forty-eight patients (59%) experienced weight loss of at least 10%. The mean BIS score was 11.23 (SD = 7.24). Body image dissatisfaction was correlated with weight loss (r = 0.31, P = 0.006), anxiety (HADS-A; r = 0.39, P < 0.001), depression (HADS-D; r = 0.46, P < 0.001), decreased sexual interest (r = 0.37, P = 0.001), decreased sexual enjoyment (r = 0.33, P = 0.004), ESAS score for pain (r = 0.25, P = 0.026), fatigue (r = 0.28, P = 0.014), drowsiness (r = 0.28, P = 0.014), shortness of breath (r = 0.27, P = 0.016), sleep disorders (r = 0.24, P = 0.036), and well-being (r = 0.29, P = 0.011). We found a significant association between the caregivers' evaluation of patients' body image dissatisfaction and patients' BIS score (r = 0.37, P = 0.049) and caregivers' distress regarding the patients' weight (DT; r = 0.58; P = 0.001). Conclusion. Body image dissatisfaction was strongly associated with patients' weight loss and with psychosocial distress among patients and their caregivers. More research is necessary to better understand the association between the severity of body image dissatisfaction and the severity of other problems in patients with cancer.
