Post Bariatric Surgery Tele-CBT Improves Mental Health and Eating Habits: JAMA

Weight regain after bariatric surgery can be a concerning issue, often leading to a recurrence of obesity-related medical conditions and a decline in quality of life. Addressing this, a recent study published in the Journal of American Medical Association has highlighted the efficacy of telephone-based cognitive behavioral therapy (tele-CBT) in improving postoperative outcomes for bariatric surgery patients.

The Multisite Randomized Clinical Trial, conducted between February 2018 and December 2021 at three hospital-based bariatric surgery programs, involved 314 English-speaking adults who had undergone bariatric surgery one year prior. Patients with severe psychiatric illnesses or active suicidal ideation were excluded. The study aimed to determine the effectiveness of tele-CBT in enhancing weight loss, managing disordered eating, and reducing psychological distress.

Participants were randomly assigned to two groups: the tele-CBT group and the control group. The tele-CBT intervention comprised six one-hour weekly sessions, with an additional booster session one month later. Meanwhile, the control group received standard postoperative bariatric care.

The primary outcome assessed was the percentage of total weight loss, while secondary outcomes included measures of disordered eating (using the Binge Eating Scale [BES] and Emotional Eating Scale [EES]) and psychological distress (using the Patient Health Questionnaire-9 item scale [PHQ-9] and Generalized Anxiety Disorder-7 item scale [GAD-7]).

The results, analyzed in early 2023, revealed that the tele-CBT intervention did not significantly impact short-term weight loss outcomes. However, it showed substantial improvements in disordered eating and psychological distress across all time points compared to the control group. The tele-CBT participants exhibited notable decreases in BES, EES, PHQ-9, and GAD-7 scores, indicating positive changes in eating behavior and mental health.

This study's findings come at a critical juncture, as obesity rates continue to rise, and bariatric surgery remains an essential tool in managing severe obesity. By addressing psychological aspects and promoting healthier eating behaviors, tele-CBT shows promise in preventing weight regain and enhancing long-term weight management success.
