OBJECTIVE: The objective of this study was to investigate the relationship between BMI and outcome of @entity712 ( @entity712 ). METHODS: We carried out a secondary analysis of the Epidemiology of Acute @entity712 in Emergency department Registry (prospective, multicenter registry following a cohort of @entity712 @entity1 from 34 Spanish emergency departments). Follow-up was at 3 months and 1 year after enrolment over the telephone and included medical history review. We analyzed revisits to the emergency department and @entity204 in relation to BMI. Significant differences were analyzed using proportional risk models including data on demographic variables, basal status, the acute episode, and @entity1 outcome. RESULTS: We included 1562 @entity1 : low weight 1.3%, normal weight 26.1%, overweight 45.3%, @entity28 24.3%, and morbidly @entity28 3.1%. BMI was inversely associated with mortality (P<0.001) but not with revisit (P=0.70). Compared with @entity1 with normal weight, the proportional risk of @entity204 among @entity1 with low weight was increased [hazard ratio (HR) 1.75, 95% confidence interval (CI) 0.95-3.23], being reduced in overweight, @entity28 and morbidly @entity28 @entity1 (HR 0.72, 95% CI 0.59-0.89; HR 0.75, 95% CI 0.58-0.96; and HR 0.42, 95% CI 0.20-0.85, respectively). These differences disappeared after adjusting the model for confounding factors and other predictive variables of mortality. CONCLUSION: BMI seems to be related to @entity712 and @entity204 , although this relationship disappeared on considering other prognostic factors and confounding variables. This finding limits the use of BMI by emergency physicians when estimating the risk of emergency department reconsultation or @entity204 in @entity712 @entity1 .
