title: Mental and physical health-related quality of life in obese patients before and after bariatric surgery: a meta-analysis.
abstract: In this meta-analysis, we review studies that compare mental and physical health-related quality of life measured with the Short-Form 36 of obese patients before and after bariatric surgery with a follow-up measure until one year. Twenty-one studies were selected to conduct the meta-analysis about the relationship between quality of life in obesity before (2680 subjects) and after (2251 subjects) bariatric surgery. Results reveal that obese patients scored less in the mental health component of the Short-Form 36 before bariatric surgery than after (d = -9.00). The same pattern could be observed in the case of the physical health component of the Short-Form 36 (d = -22.84). The results show the strong improvement that obese patients experience in both mental and physical components of the Short-Form 36 after receiving bariatric surgery.
