Examining Sleep Quality Following Sleeve Gastrectomy Among Patients with Loss-of-Control Eating

Sleep is associated with post-bariatric surgical outcomes; however, little is known about sleep in bariatric patients with loss-of-control (LOC) eating, a consistent predictor of poorer weight outcomes. This study examined sleep quality and clinical correlates in sleeve gastrectomy patients with LOC eating.
Participants (N = 145) were treatment-seeking post-operative sleeve gastrectomy patients with LOC eating. Eating-disorder features were assessed with the Eating Disorder Examination-Bariatric Surgery Version Interview (EDE-BSV) and participants completed established measures assessing sleep, health-related quality of life, perceived stress, depression, and night eating.
58.6% of participants were characterized with “poor” sleep. Poor sleep quality was significantly associated with greater eating-disorder psychopathology, physical and mental functioning, night eating, perceived stress, and less % excess weight loss (EWL); these findings remained significant after controlling for %EWL and race. Regression analyses, adjusting for correlated variables, revealed that sleep quality significantly predicted mental functioning.
Poor sleep quality was common among post-operative sleeve gastrectomy patients with LOC eating. Sleep quality was significantly associated with eating-disorder psychopathology, less post-operative weight loss, and psychosocial and physical functioning problems. These findings suggest the importance of assessment and treatment of sleep problems following sleeve gastrectomy.
