How much do we know about the factors that affect the adherence to post-bariatric surgery treatment? A systematic review
Adherence to post-bariatric surgery treatment
Palabras clave:Treatment adherence, Bariatric surgery, Predictor factors, Behavioral factors
Introduction: Adherence to treatment (ADT) after bariatric surgery (BS) is paramount for success. However, little is known about the factors that predict it.
Objective: This systematic review analyzed the extent of recent knowledge about the factors that affect behavioral aspects of ADT post-BS.
Methodology: The search was conducted in accordance with the PRISMA statement. It was performed in Web of Science, MedLine and PsycInfo, covering from 2007 to January 2021. After verification of compliance with the selection criteria, the retained studies were further evaluated for their quality.
Results: Eleven studies were analyzed. Although little more than 80% showed adequate quality, certain deficits were identified, mainly regarding external and internal validity. The most widely used behavioral indicator of ADT was attendance at follow-up appointments (63.6%), and only a study included more than one indicator. The predictors were classified into five groups: sociodemographic, psychological, medical, nutritional, and physical activity-related. The largest number of articles examined variables of the first two types, however, it is not possible to identify consistency in terms of the predictors analyzed.
Conclusions: Despite the problem that non-ADT after BS represents, few studies focus on this topic. Therefore, it is urgent to orient efforts towards systematization, since the findings should form the basis for the design of evidence-based interventions that help improve ADT in these patients.
