Background: Severe obesity deteriorates quality of life due to physical limitations and the psychological impact of its stigma. This study evaluated the quality of life of a sample of obese people who are waiting for bariatric surgery and compared with a subset which was submitted to bariatric surgery in a public health center in Brazil. Methods: The questionnaires the Medical Outcome Study 36-Item Short-Form Health Survey version 2 (SF-36) and Moorehead-Ardelt Questionnaire II (M-A-QoLQII) were applied to the subsets of pre- and post-surgery subjects. The correlation of the M-A-QoLQII categories with each domain of SF-36 for the post-surgery subset was tested. Results: Mean ages of the subsets pre (n=41) and post-surgery (n=84, 3.5 years after surgery on average) were similar (43.6±10.4 and 45.4±11.1 years, respectively). Mean body mass indices of the pre- and postsurgery subjects were 52.3±8.3 kg/m2 and 32.5±6.4 (p<0.001). All of the 8 domains of the SF- 36 of the post-surgery subset corresponded to significantly better scores than those of the presurgery one. The SF-36 domains and M-A-QoLQII categories were significantly correlated except for the social aspects domain. Conclusions: Our findings reinforced that the quality of life of severely obese subjects in Brazil may be improved after bariatric surgery. We suggest that the M-A-QoLQII may be a useful method for evaluating quality of life in our population after bariatric surgery.
