Abstract

Obesity has become the focus of global attention and is an emerging pandemic phenomenon in the 21st century. However, data regarding the weight loss, long-term reduction of BMI, physiological indicators, functional cardiovascular disease risk factors and depression and quality of life following laparoscopic bariatric surgery is lacking.

Purpose: To evaluate the effects of laparoscopic bariatric surgery on physiological indicators, depression and health-related quality of life among morbidly obese adults.

Methods: A systematic search of the articles published before June 2017 was conducted. Searches were conducted in databases including National Library of Medicine PubMed/MEDLINE, Embase, Cochrane Library, CEPS and Airiti Library. The quality of eligible studies was evaluated STROBE statement and Oxford classification. The primary outcome was HRQOL. Additional analyses comprised BMI, HbA1c, triglyceride, cholesterol, hypertension, depression, and adverse events.

Results:  Seven studies were included in systematic review. The results showed that weight-reducing laparoscopic bariatric surgery significantly reduced body weight, HbA1c, triglyceride, cholesterol, hypertension, depression, and health-related quality of life (P < .05 ~.001). The length of postoperative period was not significantly related to depression and anxiety. The higher the degree of self-awareness after surgery, the higher the scores in all aspects of life quality (P= .000 ~.021).

Implications for Practice: QOL improvements were more likely to occur within the first two years following surgery, with greater improvements in physical than psychological QOL. Laparoscopic bariatric surgery can improve the quality of life products. Future research should also focus on physical and psychological predictors of weight loss after laparoscopic bariatric surgery.
