Key result
Obesity class I was associated with a significantly lower risk of 30-day (HR 0.19; 95% CI 0.06-0.66) and 365-day mortality in polytrauma patients.
Why the study?
The obesity paradox remains controversial in polytrauma patients, with different studies presenting varying results.

Should not change polytrauma management; extends obesity paradox observations but remains hypothesis-generating.

Does obesity class I reduce mortality in polytrauma patients compared to normal weight?
Hazard Ratio: 0.19 (95% CI 0.06–0.66)
Absolute Event Rate: 2.4% vs 9%
p-value: p=0.00864
The obesity paradox survival advantage is observed in polytrauma patients specifically with obesity class I, who have significantly lower 30-day and 365-day mortality.
Luh et al. (2025) conducted a cohort in Polytrauma (n=1,234). Obesity class I (BMI 25.0-29.9 kg/m2) vs. Normal weight (BMI 18.5-22.9 kg/m2) was evaluated on 30-day all-cause mortality (HR 0.19, 95% CI 0.06-0.66, p=0.00864). Obesity class I was associated with a significantly lower risk of 30-day (HR 0.19; 95% CI 0.06-0.66) and 365-day mortality in polytrauma patients.
