Do adverse childhood experiences affect surgical weight loss outcomes?

Bariatric surgery is an effective and enduring treatment for obesity; however, variation in weight loss may occur following surgery. Many factors beyond technical considerations may influence postoperative outcomes. A better understanding of the influence of adverse childhood experiences (ACE) on surgical weight loss may improve preoperative care. Demographic and preoperative and postoperative data were prospectively obtained for 223 patients undergoing bariatric surgery. All cases were completed laparoscopically without serious complication. Patients completed the ACE questionnaire, which assesses childhood maltreatment. Patients had an average age of 48 years and 77 % were female. There was a significant reduction from preoperative to 12-month postoperative BMI (45 to 31 kg/m(2), p ≤ 0.01). The average ACE score was 2.9 and these patients were more likely than population norms to have an ACE score ≥4 (35.9 vs. 12.5 %, p < 0.001). There was a positive correlation between the number of preoperative comorbidities and preoperative ACE score (R = 0.112, p = 0.09). Patients with a high ACE score (≥6) vs. patients low ACE scores had a higher postoperative BMI at 6-months (36.9 vs. 33.4 kg/m(2), p = 0.03) and 12-months postoperatively (34.5 vs. 30.5 kg/m(2), p = 0.07). High ACE patients had higher total cholesterol (191 vs. 169 mg/dL, p = 0.02) and LDL cholesterol (116 vs. 94 mg/dL, p = 0.02) than low ACE patients 12-months postoperatively. A high preoperative ACE score decreases weight loss following bariatric surgery and may warrant an increased preoperative counseling.
