1101-P: Glycemia after Pediatric Bariatric Surgery—Outcomes and Predictors

Le résumé fourni par la source

Background: Metabolic and bariatric surgery (MBS) is a safe and efficacious treatment for children and adolescents with severe forms of obesity. However, there are few data on the effects of pre-surgical fasting insulin homeostasis measures on post-surgical weight loss or glycemia. Methods: We analyzed data from n=216/242 individuals with ≥ Class 2 obesity prospectively enrolled in the multi-center, Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) study for up to eight years. Individuals who had type 1 diabetes, a gastric band procedure, or lacked baseline data for insulin homeostasis measurements were excluded, leaving 216 individuals for analysis. Body composition was assessed through bioelectrical impedance measurements. An analysis of fasting markers of insulin homeostasis using homeostatic model of insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), or HOMA-β and outcomes following MBS was performed. Results: Our cohort had a baseline mean age of 16.5 years, BMI of 52.7 kg/m2, and was 75.4% female. At 8-year follow up, participants had a mean BMI of 43.0 kg/m2. Pre-surgical measures of insulin homeostasis did not predict change in BMI or fat mass over eight years. However, larger improvements in HbA1c were positively associated with younger baseline age, higher baseline HOMA-IR and HOMA-β, and lower baseline HbA1c. Conclusion: Baseline markers of insulin homeostasis were not significantly associated with weight loss outcomes, but did predict glycemia 8 years after MBS.
