Examining the effects of bariatric surgery on mental health

Bariatric surgery is currently the most effective treatment for obesity. While most people will experience improvements in overall quality of life and symptoms of depression after bariatric surgery, there appear to be adverse mental health outcomes for some patients, with higher rates of suicide, self-harm, mental health service use and alcohol use disorder reported following surgery. This prospective, longitudinal cohort study aims to identify the incidence, time course and risk factors for deterioration in mental health after bariatric surgery. We will assess quality of life, psychological wellbeing, symptoms of depression, alcohol and substance use via questionnaires administered to patients undergoing bariatric surgery before and for up to 3 years after surgery. Information will also be collected from the Australian and New Zealand Bariatric Surgery Registry regarding the details of the surgery and any adverse events or complications. This project would suit a student with skills or experience in clinical research.
