Sarcopenic obesity can be quantified on admission CT of the abdomen in trauma. Sarcopenic obesity is an independent predictor of mortality in major trauma.

Patients with obesity are also at risk for sarcopenia, which is difficult to recognize in this population. The study examines whether sarcopenic-obesity (SO) is independently associated with mortality in trauma.

Using a retrospective database, researchers performed logistic regression analysis. . Admission CT scans were used to identify SO by calculating the visceral fat to skeletal muscle ratio >3.2.

- Of 883 patients, the prevalence of SO was 38%.

- Patients with SO were more likely to be male, older, and less likely to have an injury severity score (ISS)???24.

- Using multivariable logistic regression analysis, SO was independently associated with mortality.

- Causal mediation analysis found admission hyperglycemia as a mediator for mortality.

Conclusively, sarcopenic obesity is an independent predictor of mortality in major trauma.
