    Journal: J Nurs Scholarsh; 2017 Jan; 49(1):63-72. PubMed ID: 27779822.
    Abstract:
    PURPOSE: We investigated the relationships among geriatric syndrome, physiological functions, and body composition in community-dwelling older people with varying nutritional statuses. Other factors correlated with nutritional status in community-dwelling older people were also explored. BACKGROUND: The World Health Organization has initiated preventive programs for addressing malnutrition. However, few studies have focused on the correlations among geriatric syndrome, physiological functions, and body composition in older people at risk of malnutrition. DESIGN: We conducted a cross-sectional study. METHODS: Older people who lived in an urban Taiwanese community were recruited for this research study. The inclusion criteria were age 65 years or older, ability to communicate in Taiwanese, clear consciousness, and ability to communicate independently. The nutritional status of participants was evaluated with the Mini Nutritional Assessment-Short Form. The frailty status was assessed with the Study of Osteoporotic Fractures (SOF) index. The SOF index included the following three items: body weight loss of >5% within 1 year, difficulty in standing from a sitting position in a chair without an armrest five times, and feeling deprived of energy. Participants over 65 years of age, living in a community and without mental illness or acute disease were included in the study. FINDINGS: Compared with well-nourished older adults, those at risk of malnutrition were predominantly male; presented with lower body weight, lower body mass index values, lower skeletal mass indices, and poorer muscle strength; and were unable to rise from a seated position in a chair without using the armrest five times. Subjects at risk of malnutrition were less energetic, were more commonly characterized as being sarcopenia, and demonstrated frailty. Body composition analysis demonstrated that a skeletal muscle index of approximately 9.93 and a body fat mass of less than 12.25 kg were related to an increased risk of malnutrition. Older people who were frail exhibited a particularly high risk of malnutrition. CONCLUSIONS: The results revealed that the evaluation of malnutrition risk should be conducted in older persons living in the community. Frailty in particular was identified as a major risk factor for malnutrition in community-dwelling elderly persons. CLINICAL RELEVANCE: Community nurses should pay attention to the nutritional conditions of community-dwelling elderly persons. Community nurses should assess the at-risk population and provide effective preventive strategies and programs to reduce the prevalence of malnutrition and frailty.
