Association between body mass index and outcome in Japanese XXXX @entity1 .

@entity1 @entity64 @entity28 @entity385
AIM: An association between body mass index (BMI) and @entity64 outcome have been reported, but the results are controversial. The aim of the present study was to evaluate whether BMI is associated with @entity385 outcome. METHODS: Consecutive Japanese acute @entity385 @entity1 were analyzed. BMI was categorized as underweight (BMI <18.5   kg/m(2) ), normal weight (18.5-24.9   kg/m(2) ) and @entity28 (>= 25   kg/m(2) ). BMI and short-term and long-term outcomes were examined. Short-term outcomes were evaluated using the modified Rankin scale score at hospitalization and discharge; modified Rankin scale >= 3 was defined as a poor outcome. Long-term outcomes were evaluated by all-cause mortality. The recurrence rate was also evaluated in each BMI group. Values of P   <   0.05 were considered significant. RESULTS: A total of 1206 acute @entity385 @entity1 (760 @entity1 ; mean age 72.5 years) were analyzed in the present study. There were 111 underweight cases (9.2%), 785 normal weight cases (65.1%) and 310 @entity28 cases (25.7%). The underweight group had a significantly higher rate of poor short and long-term outcomes than the normal weight group. The outcomes of the @entity28 group were not significantly different from those of the normal weight group. Recurrence was not significantly different among the groups. CONCLUSIONS: Lower BMI might be a predictor of poorer short-term and long-term @entity64 outcomes. Geriatr Gerontol Int 2016;       :       -      .
