Agreement between different versions of MNA

Abstract

The different versions of MNA gave similar results in the classifications of subjects and in comparison with nutritional and biochemical parameters. Moreover MNA versions that did not considered BMI seem to be more effective in singling out subjects with risk factors related to malnutrition (disability, reduced strength and calf circumference, anaemia).

Evaluation of the Iranian Mini Nutritional Assessment Short-Form in Community-dwelling Elderly

“…Moreover, they 4 reported 88.9% specificity and 76.4% PPV that was in contrast to our results. Similar to our findings, Donini et al 3 found that CC-MAC-MNA had 81.1% sensitivity and 94.4% NPV in comparison with the MNA. However, our specificity (62.5%) and positive predictive values (68.18%) were lower than the values (97.1% specificity and 94.2% PPV) reported by Donini et al 3 in free living or institutionalized elderly subjects.…”

Relatively low specificity found within our study means that residents with false-positive diagnoses of under-nutrition might withdraw resources from those in real need of nutritional measures.…”

“…In this regard, several tools are currently available for detecting under-nutrition. 3 Among these methods, the Mini Nutritional Assessment (MNA) has been revealed as probably the best and appropriate screening tool to detect malnourished elders and those at risk of malnutrition. 4 The MNA full form was developed and published in 1994 and consisted of eighteen items including anthropometric measurements, general, dietary and self-assessments.…”

Malnutrition risk and hospitalization in elderly assisted in Primary Care

“…One explanation for the lack of association between BMI and hospitalization would be the high frequency of BMI ≥ 23 kg/m 2 of our sample (mean BMI = 26.4 ± 4.8 kg/m 2 ). Additionally, BMI does not appear to be a more reliable indicator of changes in nutritional status of the elderly, since it does not reflect changes in body composition (fat mass, lean body mass and body water) due to aging 26 . Winter et al 27 observed that even in the community-dwelling older adults who have an annual health assessment, one in six is at risk of malnourishment, of whom one-third have a BMI of 25 kg/m 2 or higher.…”

“…Tilsvarande kan det vere eit alternativ å måle omkrins av overarm og legg, for å få ein indikasjon på ernaeringsstatus, når vekta manglar (Donini et al, 2013). Studiar opnar også for at omkrins av legg, kan erstatte KMI i MNA-SF (Skates & Anthony, 2012;Guigoz, 2006).…”
