Using Department of Veterans Affairs administrative data from fiscal years 2002–2006, we examined a cohort of patients hospitalised with a discharge diagnosis of pneumonia. Body mass index was categorised as underweight (<18.5 kg·m−2), normal (18.5–24.9 kg·m−2, reference group), overweight (25–29.9 kg·m−2), obese (30–39.9 kg·m−2) and morbidly obese (≥40 kg·m−2). Our primary analyses were multi level regression models with the outcomes of 90-day mortality, intensive care unit (ICU) admission, need for mechanical ventilation and vasopressor utilisation. The cohort comprised 18 746 subjects: 3% were underweight, 30% were normal, 36% were overweight, 27% were obese and 4% were morbidly obese. In the regression models, after adjusting for potential confounders, morbid obesity was not associated with mortality (OR 0.96, 95% CI 0.72–1.28), but obesity was associated with decreased mortality (OR 0.86, 95% CI 0.74–0.99). Neither obesity nor morbid obesity was associated with ICU admission, use of mechanical ventilation or vasopressor utilisation. Underweight patients had increased 90-day mortality (OR 1.40, 95% CI 1.14–1.73). Although obesity is a growing health epidemic, it appears to have little impact on clinical outcomes and may reduce mortality for veterans hospitalised with pneumonia. ER -
