520		a Objective: This study aimed to investigate the risk of malnutrition and to evaluate the psychometric properties of the Subjective-Objective Malnutrition Risk Assessment (SOMRA), SOMRA cut-offs and Swedish-Guidelines on Malnutrition Risk Assessment (SGMRA) for Swedish people aged ≥ 60 years.Setting: This study included both older people living at home and those in special housing.Participants: 1222 of the 1402 subjects aged ≥ 60 years who had participated in the baseline survey (2001–2003) as part of the ongoing National Study on Aging and Care-Blekinge (SNAC-B) were included because they had provided complete information on Mini-Nutritional Assessment (MNA).Measurements: The risk of malnutrition was estimated by the SOMRA, MNA, and SGMRA. To measure concurrent validity, the Receiver Operating Characteristics (ROC) curve, Cohen’s kappa (κ) and Spearman’s rank correlation coefficient rho (rs) were used. Youden’s index (J) was computed to assess the optimal cut-off on SOMRA. Cronbach’s alpha (α) was used to test reliability.Results: The risks of malnutrition measured by SOMRA, MNA and SGMRA were 6.5%, 8.6% and 20.9%, respectively. The risk was higher among older people living in special housing compared to those at home (p < 0.05). Different optimal cut-offs on SOMRA were observed for residents living at home (≥ 1) and those in special housing (≥ 3). Compared to SGMRA, the SOMRA and SOMRA cut-off ≥ 3 gave higher values for J (0.68, 0.81, and 0.84, respectively), κ (0.59, 0.77, and 0.84, respectively) and rs (0.64, 0.78, and 0.84, respectively) for the older people in special housing. The reliability for SOMRA was α = 0.71.Conclusion: The risk of malnutrition was higher among older people in special housing than among those living at home. For the people in special housing, the SOMRA and SOMRA cut-off ≥ 3 showed higher concurrent validity with MNA compared to the SGMRA, but not for older people living at home. SOMRA includes six items, takes less time to implement and is composed of both subjective and anthropometric measurements; therefore, it is suitable for use in special housing and/or clinical settings to identify the risk of malnutrition or the need for nutritional support.
