Correlation between the Beck Depression Inventory and bariatric surgical procedures

Area of Science:

• Bariatric Surgery
• Psychosocial Health
• Obesity Management

Background:

• The Beck Depression Inventory (BDI) screens depression in obese patients seeking bariatric surgery.
• Weight loss post-gastric bypass correlates with improved BDI scores.
• The impact of different bariatric procedures on BDI scores remains unclear.

Purpose of the Study:

• To assess the relationship between bariatric procedures and BDI score changes, controlling for baseline BDI and psychosocial factors.
• To evaluate the correlation between BDI score changes and weight loss at 6-12 months post-surgery.

Main Methods:

• Prospective enrollment and retrospective review of 137 bariatric surgery patients (gastric band, sleeve gastrectomy, gastric bypass).
• Analysis of BDI changes, adjusted for pre-surgical BDI scores.
• Examination of demographic and psychological factors influencing BDI changes.

Main Results:

• A significant decrease in Body Mass Index (BMI) and BDI scores was observed across all patients.
• Changes in BDI scores did not significantly correlate with BMI changes or weight loss at 6-12 months.
• Patients employed and without a psychiatric history showed greater BDI score improvements.

Conclusions:

• BDI score improvements after bariatric surgery are independent of the surgical procedure and weight loss.
• Positive psychosocial factors, such as employment and absence of psychiatric history, are linked to greater depression symptom reduction.
