Abstract

This study examined the effects of intensive behavioural therapy (IBT) for obesity (IBT-alone), IBT plus liraglutide 3.0 mg/day (IBT-liraglutide), and IBT-liraglutide combined with 12 weeks of a portion-controlled diet (Multicomponent) on changes in general health-related (HR) quality of life (QoL) and weight-related QoL. Adults with obesity (79.3% female; 54.0% white; 44.7% black; mean age = 47.6 ± 11.8 years and body mass index = 38.4 ± 4.9 kg/m2 ) were randomized to IBT-alone (n = 50), IBT-liraglutide (n = 50) or Multicomponent (n = 50). General HRQoL was measured with the Short Form-36 (SF-36), and weight-related QoL was assessed with the Impact of Weight on Quality of Life-Lite scale. At week 52, participants in the three groups lost 6.1 ± 1.3%, 11.5 ± 1.3% and 11.8 ± 1.3% of initial body weight, respectively. Both liraglutide-treated groups were significantly more likely than IBT-alone to achieve clinically meaningful improvements in total weight-related QoL. They also both achieved greater improvements than IBT-alone in weight-related public distress and in general mental health, as measured by the SF-36 mental component summary score. Independent of treatment group, greater categorical weight loss was associated with greater improvements in several domains of both general and weight-related QoL. The addition of liraglutide to IBT appeared to improve aspects of both general HRQoL and weight-related QoL.
