The 'mini nutritional assessment' (MNA) and the 'determine your nutritional health' checklist (NSI checklist) as predictors of morbidity and mortality in an elderly Danish population

The purpose of the present study was to evaluate the capacity of the 'Deter mine Your Nutritional Health' Checklist (NSI Checklist) and the 'Mini Nutri tional Assessment' (MNA) methods to predict nutrition-related health proble ms. Data were from the Danish part of the 'Survey in Europe of Nutrition in the Elderly, a Concerted Action' (SENECA) baseline survey from 1988, and t he follow-up study from 1993. Based on the baseline survey thirty-nine (19. 3 %) of the subjects were classified at high nutritional risk, 103 (51%) we re considered at moderate nutritional risk and sixty (29.7 %) were within t he 'good' range according to the criteria in the NSI Checklist. With the MN A, 171 subjects were classified according to their nutritional risk into a well-nourished group, comprising 78.4 %, and a group who were at risk of un dernutrition, comprising 21.6 % at baseline. A total of 115 subjects partic ipated in the follow-up study. The mortality rate and the prevalence of var ious morbidity indicators were compared between the different risk groups. The analysis showed that subjects with a high MNA score (greater than or eq ual to 24) had significantly lower mortality (rate ratio estimate: 0.35; 95 % Cl 0.18, 0.66) compared with subjects with a low MNA score (less than or equal to 23.5). In contrast, the NSI Checklist score was not a significant predictor of mortality (rate ratio estimate: 1.45; 95 % Cl 0.78, 2.71). Th e sixteen Domes judged to be at high nutritional risk by the NSI Checklist in 1988, had more acute diseases (P < 0.001) than the rest of the participa nts, between 1988 and 1993. No significant differences were found in the pa rticipation rates, hospitalization rates, physician visits, need of help or weight loss between the groups. The thirteen Domes judged to be at risk of undernutrition in 1988 by the MNA, had a lower participation rate (P < 0.0 1) and higher occurrence of acute disease (P < 0.05), need of help (P < 0.0 5), and weight loss (P < 0.001) than the well-nourished group, between 1988 and 1993. No significant differences were found in hospitalization rates a nd physician visits between the two groups. In conclusion, the results indi cate that modified versions of the NSI Checklist and the MNA are capable of identifying a group of 70-75-year-old subjects with increased risk of cert ain nutrition-related health problems. Further, an MNA score less than or e qual to 23.5 predicts mortality in a Danish population.
