Canadian women are twice as likely to be severely obese compared to men, are more likely to be physically inactive, and comprise the majority of patients undergoing bariatric treatment for severe obesity. Physical activity (PA) is one of the strongest predictors of successful long-term weight management and is a recommended adjunct to bariatric surgery. However, patients often do not increase levels of PA following surgery and physical inactivity among severely obese women remains poorly understood. Twelve women (mean age 47±9 years), who had undergone bariatric surgery in the last two years, were interviewed to explore perceptions of barriers and facilitators to PA.
