摘要

Background and aim

To investigate the changes of psychology, eating behavior, sleep, cell phone use and weight management in patients with weight loss before and after operation.

Methods

A convenience sampling method was used to select 53 patients from the weight loss center of a third class hospital in Beijing. A self-controlled study design was adopted before and after weight loss surgery to observe the changes of patients’ eating behavior, sleep status, mobile phone dependence, psychological status and weight management before and after weight loss surgery.

Results

1 month after weight loss surgery, the overall psychological status of patients was significantly improved (P < 0.05), the proportion of excess weight loss after weight loss was positively correlated with preoperative psychological status, multiple linear regression results showed that psychological status before weight loss was the main risk factor for weight management after weight loss. Before and after bariatric surgery, there were significant differences in body mass, SCL-90 symptom self-evaluation results, and the dimensions of cognitive restriction in eating behavior (P<0.05).

Conclusion

The psychological status of patients after bariatric surgery was significantly improved. Preoperative psychological status was the main risk factor for excess weight loss in bariatric surgery patients.
