Weight changes following antidiabetic mediation use: Real‐world evidence from health system data

Abstract

Objective: Newer antidiabetic medications such as sodium-glucose co-transporter 2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP1RA) result in weight loss in clinical trials. However, the real-world effectiveness remains unclear.The magnitude of weight change associated with antidiabetic medication using realworld data was examined.Methods: Patients with diabetes who initiated SGLT2i (n = 906), GLP1RA (n = 782), dipeptidyl peptidase-4 inhibitors (DPP4i, n = 1881), or sulfonylureas (n = 3255) in Geisinger Health System were identified. Outcomes were percent weight change per year and time to 5% weight loss. Propensity scores were used to account for differences across groups. Results:The mean � SD age of patients was 57.5 � 14.1 years, 3381 (49.5%) were female, and 6450 (94.5%) had body mass index ≥25 kg/m 2 . Compared with sulfonylureas, newer antidiabetic medications were associated with significant weight loss (−3.2% [95% confidence interval: −3.8%, −2.6%] per year for SGLT2i; −2.9%[−3.6%, −2.3%] per year for GLP1RA; and −1.7% [−2.1%, −1.3%] per year for DPP4i). SGLT2i and GLP1RA were also associated with significant weight loss compared with DPP4i. Among patients with overweight or obesity, SGLT2i and GLP1RA users were more likely to achieve 5% weight loss compared with sulfonylureas and DPP4i. Conclusions:In real-world practice, SGLT2i and GLP1RA were associated with significant weight loss compared with sulfonylureas and DPP4i. These results may further motivate uptake of SGLT2i and GLP1RA, especially among patients who were overweight or had obesity.
