Abstract
Purpose
In this study, we examined the relationship between pre-operative internalized weight bias and 12-month post-operative weight loss in adult bariatric surgery patients.
Methods
Bariatric surgery patients (n = 170) from one urban and one rural medical center completed an internalized weight bias measure (the weight bias internalization scale, WBIS) and a depression survey (Beck depression inventory-II, BDI-II) before surgery, and provided consent to access their medical records.
Results
Participants (BMI = 47.8 kg/m2, age = 45.7 years) were mostly female (82.0 %), White (89.5 %), and underwent gastric bypass (83.6 %). The average WBIS score by item was 4.54 ± 1.3. Higher pre-operative WBIS scores were associated with diminished weight loss at 12 months after surgery (p = 0.035). Pre-operative WBIS scores were positively associated with depressive symptoms (p < 0.001).
Conclusion
Greater internalized weight bias was associated with more depressive symptoms before surgery and less weight loss 1 year after surgery.
