Influence of overweight and obesity on the mortality of hospitalized patients with community-acquired pneumonia

Abstract

BACKGROUND: Obesity is associated with a better prognosis in patients with community-acquired pneumonia (the so-called obesity survival paradox), but conflicting results have been found. AIM: To investigate the relationship between all-cause mortality and body mass index in patients with community-acquired pneumonia. METHODS: ). The primary outcome was all-cause hospital mortality. RESULTS: < 0.001) were independently associated with mortality. CONCLUSION: All-cause mortality of normal-weight patients was higher than overweight/ obesity patients, lower than that of underweight patients. Neutrophil counts, albumin levels, Confusion-Urea-Respiration-Blood pressure-65 score, and intensive care unit admission were independently associated with mortality in patients with community-acquired pneumonia.
