Is body mass index associated with hospital mortality in critically ill patients?
Odds Ratio: 0.86 (95% CI 0.83–0.9)
In critically ill patients, obesity (BMI 30-39.9 kg/m²) is associated with lower hospital mortality, supporting the existence of an obesity paradox in the ICU setting.
Pickkers et al. (2013) conducted a cohort in critically ill patients (n=154,308). Obesity (BMI 30-39.9 kg/m2) was evaluated on hospital mortality (OR 0.86, 95% CI 0.83-0.90). Obesity (BMI 30-39.9 kg/m2) was associated with a lower risk of hospital mortality in critically ill patients (adjusted OR 0.86; 95% CI 0.83-0.90).
