Older adults with type 2 diabetes, with and without semaglutide treatment

What This Study Found

Semaglutide treatment over 24 months reduced both BMI and muscle mass in older adults with type 2 diabetes. Grip strength initially improved then declined in men, while gait speed decreased in both sexes. Higher doses predicted greater muscle loss.

Key Numbers

220 semaglutide patients, 212 controls. Sarcopenia prevalence 27.7%. Significant reductions in BMI and ASMI in semaglutide group. Gait speed reduced in both sexes. Semaglutide dose, baseline ASMI, and gait speed were independent predictors of muscle loss.

How They Did This

Retrospective cohort study comparing semaglutide-treated elderly T2DM patients to matched controls. Measured ASMI, grip strength, and gait speed over 24 months. Multivariable linear regression for predictors.

Why This Research Matters

Older adults with diabetes are already at risk for muscle wasting. Semaglutide accelerates this loss, especially at higher doses. Doctors need to monitor muscle mass and function in elderly patients on this drug.

What This Study Doesn't Tell Us

Retrospective design. No randomization. Potential confounding by indication (sicker patients may be prescribed semaglutide). No dietary or exercise data collected. Single-center study.
