Abstract
Background
Negative psychological sequelae have been reported after bariatric surgery. It is
unclear which factors affect psychological function in the first postoperative years.
Objective
Evaluation of significant predictors of improved psychological function following
bariatric surgery by analyzing data from the BODY-Q questionnaire.
Setting
Multicenter prospective cohort in 3 centers located in The Netherlands and Denmark.
Methods
The BODY-Q questionnaire was used to assess 6 domains of health-related quality of
life. The domain of interest, psychological function, consists of 10 questions from
which a converted score of 0 (low) to 100 (high) can be calculated. Linear mixed models
were used to analyze which patient characteristics were most predictive of the psychological
function score. Secondary outcomes of interest were cross-sectional scores of psychological
function and the impact of weight loss, and the effect of major short-term complications
on psychological function.
Results
Data were analyzed from 836 patients who underwent bariatric surgery from 2015 to
2020. Patients with lower expectations concerning weight loss (<40% desired total
weight loss), higher educational level, no history of psychiatric illness, and employment
before bariatric surgery demonstrated the highest psychological function scores after
bariatric surgery. At 1 and 2 years after bariatric surgery, more weight loss was
associated with significantly higher psychological function scores. Experiencing a
major short-term complication did not significantly impact psychological function.
Conclusions
Several relevant predictors of improved postoperative psychological function have
been identified. This knowledge can be used to enhance patient education preoperatively
and identify patients at risk for poor psychological functioning postoperatively.
