Mental Health, Dysfunctional Eating Pattern and Weight Trajectory in Subjects Undergoing Bariatric Surgery

What this Trial Is About

This research aims to understand how eating habits, especially unhealthy behaviors, and certain psychological factors relate to weight changes after bariatric surgery over both short and long periods. It is a five-year, prospective, multicenter observational study including people with obesity undergoing primary bariatric surgery and a control group of obese individuals not undergoing surgery but matched by age, sex, and BMI. The study includes two groups: those having primary laparoscopic gastric bypass or sleeve gastrectomy surgeries between September 2020 and September 2021, who will be evaluated before surgery and at 4 months, 1 year, 3 years, and 5 years after surgery; and a control group of obese subjects not eligible for surgery who will be evaluated once. Psychological and behavioral data will be collected through validated online questionnaires completed by participants. Participants will provide information about their weight changes, psychological states, eating patterns, mood, stress, impulsivity, substance use, personality traits, depression, economic status, physical activity, social support, and quality of life. Food intake will be recorded over three days for analysis. The primary outcomes include percentages of total weight lost, excess weight lost, total weight regained, and excess weight regained over five years. Data on demographics, comorbidities, and anthropometric measures will also be collected to support the analysis.
