title: Impact of Malnutrition on Physical, Cognitive Function and Mortality among Older Men Living in Veteran Homes by Minimum Data Set: A Prospective Cohort Study in Taiwan.
abstract: OBJECTIVE
  To evaluate the prevalence of malnutrition and its impact on mortality, functional decline and cognitive impairment among elder residents in long-term care settings.
  
  
  METHODS
  A prospective cohort study.
  
  
  METHODS
  Two veteran homes in Taiwan.
  
  
  METHODS
  A total of 1,248 male residents aged equal or more than 65 years.
  
  
  METHODS
  Charlson's comorbidity index (CCI), Minimum data set (MDS), resident assessment protocols (RAP), Activity of daily living-Hierarchy scale, Cognitive Performance Scale, MDS Social engagement scale.
  
  
  RESULTS
  The mean age of participants is 83.1 ± 5.1 years, and the prevalence of malnutrition was 6.1%. Inadequate dietary content (57.9%) and unintentional weight loss (31.6%) account for the majority of malnutrition identified by MDS tool. Higher 18-month mortality rate (25% vs. 14.2%), higher baseline CCI (median 1 vs. 0), and higher baseline sum of RAP triggers (median 8.5 vs. 5) were noted among residents with malnutrition. Furthermore, malnutrition was shown predictive for functional decline (OR: 3.096, 95% CI: 1.715-5.587) and potential cognitive improvement (OR: 2.469, 95% CI: 1.188-5.128) among survivors after adjustment for age, body mass index and CCI.
  
  
  CONCLUSIONS
  Malnutrition among elder men residing in veteran homes was associated with multimorbidities and higher care complexity, and was predictive for mortality and functional decline.
