摘要

Background

This study was conducted to assess the association between lifestyle risk factors (LRF) and odds of binge eating disorder (BED) 2 years post laparoscopic sleeve gastrectomy (LSG) using lifestyle score (LS) and machine learning (ML) models.

Methods

In the current study, 450 individuals who had undergone LSG 2 years prior to participation were enrolled. BED was assessed using BES questionnaire. The collected data for LRF included smoking, alcohol consumption, physical activity (PA), fruit and vegetable intake, overweight/obesity, and percentage excess weight loss (EWL%). ML models included: logistic regression (LG), KNN, decision tree (DT), random forest (RF), SVM, XGBoost, and deep learning or artificial neurol network (ANN). Additionally, accumulative LRF was assessed using LS.

Results

One hundred and twenty-two subjects (26.1%) met the criteria for BED 2 years after LSG. Participants who were in the highest quartile of the lifestyle score (nearly worst) had significantly three times higher odds of BED compared to the lowest quartile (nearly optimal) (p trend = 0.01). Furthermore, RF, LG, SVM, and ANN had the highest accuracy (about 75%) in predicting BED compared to other ML models (between 60 and 72%). Among the lifestyle risk factors, insufficient PA, lower vegetable consumption, a higher level of BMI, and lower EWL% were independently associated with BED (p < 0.05).

Conclusions

Our findings indicate that poor lifestyle patterns are associated with the development of BED, in contrast to non-BED individuals. Given the prevalence of this disorder among LSG participants, lifestyle risk factors must receive special attention after BS.
