BACKGROUND/OBJECTIVES: We aimed to quantify the association of @entity6288 with length of hospital stay (LOS) and to identify factors associated with @entity6288 among hospitalized @entity1 . SUBJECTS/METHODS: A total of 655 @entity1 composed the study sample. A longitudinal study was conducted in a University Hospital. @entity6288 was defined, according to European Consensus criteria, as low muscle mass (bioelectrical impedance analysis) and low muscle function (handgrip strength). Logistic regression, Kaplan-Meier and Cox adjusted proportional hazards methods were used. LOS was determined from the date of hospital admission and discharge home (event of interest). RESULTS: @entity1 were aged 18 to 90 years (24.3% sarcopenic). Factors associated with @entity6288 were male gender, age    65 years, moderate or severe @entity734 , undernutrition and being admitted to a medical ward. Sarcopenic @entity1 presented a lower probability of being discharged home (hazard ratio (HR), 95% confidence interval (CI)=0.71, 0.58-0.86). However, after stratifying for age groups, this effect was visible only in @entity1 aged <65 years (HR, 95% CI= 0.66, 0.51-0.86). Moreover, sarcopenic overweight or @entity28 @entity1 presented a higher probability of being discharged home (HR, 95% CI=0.78, 0.61-0.99) than nonoverweight sarcopenic @entity1 (HR, 95% CI=0.63, 0.48-0.83). CONCLUSIONS: Being male, age    65 years, presenting @entity734 , being undernourished and admitted to a medical ward were factors associated with @entity6288 among hospitalized adult @entity1 . @entity6288 is independently associated with longer LOS, although this association is stronger for @entity1 aged <65 years. Moreover, sarcopenic overweight was associated with a higher probability of discharge home than @entity6288 .European Journal of Clinical Nutrition advance online publication, 16 December 2015; doi:10.1038/ejcn.2015.207.
