Improvement of Work Ability After Weight Loss Surgery: Results of a Longitudinal Study of Patients Suffering from Extreme Obesity Before and 4 Years After Bariatric Surgery.

Purpose: Body mass index (BMI) is directly associated with employment status. Our longitudinal prospective study is aimed at ascertaining whether work ability index (WAI) 4 years after surgery remains improved, such as 1 year after surgery, or changes and whether socio-demographic or psycho-social factors influence changes in work ability.

Materials And Methods: 197 bariatric surgery candidates were recruited.
