Factors associated with malnutrition in community-dwelling disabled elderly ~the KANAGAWA-AICHI Disabled Elderly Cohort (KAIDEC) Study~

要旨

AIM: This study aimed to identify factors associated with malnutrition in community-dwelling disabled elderly. METHODS: A cross-sectional study of baseline data for 1,142 community-dwelling elderly (81.2±8.7 years) from of the KANAGAWA-AICHI Disabled Elderly Cohort (KAIDEC) study was conducted. The data included the participants' demographic characteristics, nutritional status (Mini Nutritional Assessment short-form: MNA-SF), dysphagia status (Dysphagia Severity scale: DSS), comorbidity, basic activities of daily living (bADL), hospitalization with in the past three months and care level according to the Long-Term Care Insurance program. The participants were considered to be in malnutrition or at risk of malnutrition if their MNA-SF score was 0-7 or 8-11, respectively. The chi square test, analysis of variance, Jonckheere-Terpstra trend test and logistic regression analysis were used for the statistical analysis. RESULTS: A total of 16.7% of the participants were classified as having malnutrition. In addition, a higher prevalence of malnutrition was associated with a higher care level in the long-term care insurance program, and malnutrition was associated with a lower bADL score, the presence of dysphagia and dementia and hospitalization with in the past three months. CONCLUSIONS: The present study demonstrated that malnutrition in community-dwelling disabled elderly is associated with a lower bADL score, the presence of dysphagia and dementia and hospitalization with in the past three months.
