    Abstract:
    BACKGROUND: The risk of malnutrition is widely recognized in institutional settings but few studies have been conducted among community-dwelling older people. The objective of this study was to describe the nutritional status and factors associated with possible malnutrition among community-dwelling older people. METHODS: A randomly selected sample (n = 696) of persons aged ≥ 75 years were included in the study. Baseline information was obtained for nutritional status (mini nutritional assessment short-form MNA-SF), depressive symptoms (15-item geriatric depression scale), cognitive status (mini-mental state examination MMSE) and daily activities (Barthel ADL index and Lawton and Brody IADL scale), self-reported health, oral health and medication use. Univariate and multivariate regression analyses were conducted to identify demographical, clinical and functional factors associated with possible malnutrition. RESULTS: Of the 696 participants, 15% had possible malnutrition. In the univariate analysis, low MNA-SF scores were associated with advanced age, poor self-rated health, dry mouth/chewing problems, depressive symptoms and an increasing number of drugs in regular use. Higher albumin level, ADL, IADL and MMSE scores, and the ability to walk 400 m independently were inversely associated with possible malnutrition. In the multivariate analysis, dry mouth/chewing problems (OR 2.01, 95% CI: 1.14-3.54), IADL (OR 0.85, 95% CI: 0.75-0.96) and MMSE scores (OR 0.90, 95% 0.85-0.96) were independently associated with possible malnutrition. CONCLUSION: Being at risk of malnutrition was common among community-dwelling older people. Problems with mouth, IADL and cognitive impairments were linked to possible nutritional risks.
