Psychiatric diagnosis and weight loss following gastric surgery for obesity.
BACKGROUND
The authors examined associations between lifetime Axis I and Axis II disorders and weight loss following gastric surgery for morbid obesity.


METHODS
44 morbidly obese subjects who had undergone vertical banded gastroplasty (VBG) were systematically interviewed with the Diagnostic Interview Schedule (DIS) and were administered the Personality Diagnostic Questionnaire (PDQ). Subjects were followed-up 6 months post-VBG to determine weight loss.


RESULTS
The subjects had a mean +/- SD age of 37.7 +/- 10.6 years. Their baseline weight was 135.3 +/- 28.0 kg and their baseline body mass index (BMI) was 50.0 +/- 7.4. 34 (77%) were female. Results of linear regressions show a significant association between baseline BMI and weight loss at 6-month follow-up. After adjustment for baseline BMI, there was a non-significant trend toward increased weight loss in association with alcohol abuse/dependence. Similarly, among our analysis of 41 subjects who had received the PDQ, we found a non-significant trend toward increased weight loss in association with "any" PDQ diagnosis and with antisocial personality disorder/trait after adjusting for baseline BMI.


CONCLUSIONS
The data suggest that Axis I and Axis II diagnoses were not predictive of weight loss following VBG during a 6-month follow-up.
