UMS member, Professor Prevost along with colleagues published the following study:
Impact of bariatric surgery on clinical depression. Interrupted time series study with matched controls.
This study ‘aimed to evaluate whether clinical depression is reduced after bariatric surgery’, given that ‘obesity is associated with depression’.
Using an interrupted time series design with over 3,000 participants, the study concluded that ‘bariatric surgery may be associated with a modest reduction in clinical depression over the initial post-operative years but this is not maintained’.
