Background:
This study examined differences in gastric bypass surgical outcomes by comparing two groups of female patients: those with a history of sexual abuse (SA) and those without a history of sexual abuse (NSA).
Methods:
Participants who agreed to participate in the study were assessed at either 6-18 months or 19-40 months postsurgery. Outcome measures included body mass index (BMI), level of depression as measured through the Beck Depression Inventory, level of self-esteem as measured through the Rosenberg Self-esteem Scale, and BISS as measured through the Body Image State Scale. Two-by-two analyses of variance (ANOVAs) were conducted for each of the four outcome variables.
Results:
ANOVA results revealed that BMI was the only variable to be found statistically significant among the four dependent measures. At 6-18 months postsurgery, the SA group had significantly higher BMI than the NSA group. Compared BMI during the two postsurgery time periods, the SA group had a significantly lower BMI at 19-40 months than the SA group at 6-18 months postsurgery.
Conclusion:
The results suggest that females with a history of sexual abuse did not differ from their counterparts with regard to depression, self-esteem, and body dissatisfaction at baseline, as well as years after surgery. Given the improvement in BMI from the sexual abuse group at 6-18 months postsurgery to 19-40 month postsurgery, patients may not be as concerned with maintaining excess weight as a defense against potential future abuse as originally proposed.
