Abstract
This study was aimed to assess agreement and diagnostic accuracy of the Iranian version of Mini Nutritional Assessment short-form (MNA-SF) against the original MNA, as a gold standard in community-dwelling elderly. The full MNA and 9-item MNA-SF comprising questions regarding clinical status, dietary assessment and self-perception of health status and nutri-tion together with mid-arm and calf circumference measurements without in-cluding the body mass index (BMI) were completed for 205 volunteers aged 65 or older recruited from all over Markazi Province (Iran). Correlation, diagnostic accuracy and agreement between the MNA-SF and full MNA were calculated. The MNA and the MNA-SF classified 45.4% and 64.4% of the sub-jects as malnourished or at risk of malnutrition, respectively. Substantial agree-ment between the MNA-SF and full MNA was observed (Kappa=0.633). The MNA-SF correlated strongly with the full MNA (r=0.868, P<0.001). The MNA-SF showed high sensitivity (96.77%) and negative predictive values (95.89%), relatively high specificity (62.5%) and positive predictive values (68.18%) and fair accuracy (Area under curve =0.796). Iranian MNA-SF seems to be an applicable screening tool for quick detection of malnutrition or at risk of malnutrition in community-dwelling elderly especially when BMI is unavailable.
Highlights
Nutritional status of older people is an important determinant of quality of life.1It is recognized as an important predictor of morbidity and mortality related to increased demands on health services and higher hospitalization rate.[2]
It consists of 18 questions grouped into 4 parts: anthropometry [body mass index (BMI), weight loss, mid upper arm and calf circumferences], clinical status, dietary assessment and self-perception of health status and nutrition
The results according to the Mini Nutritional Assessment short-form (MNA-SF) were 5.4% (n=11) malnourished individuals, 59% (n=121) of individuals at risk of malnutrition and 35.6% (n=73) well-nourished subjects
Summary
Nutritional status of older people is an important determinant of quality of life.1It is recognized as an important predictor of morbidity and mortality related to increased demands on health services and higher hospitalization rate.[2] nutritional assessment and early identification of the risk of malnutrition plays a key role in the successful interventions in elderly population In this regard, several tools are currently available for detecting under-nutrition.[3] Among these methods, Health Promotion Perspectives, Vol 5, No 2, 2015; P:98-103 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.[5] This test classifies the individuals as "malnourished", "at risk of malnutrition" and "well nourished". Conclusion: Iranian MNA-SF seems to be an applicable screening tool for quick detection of malnutrition or at risk of malnutrition in community-dwelling elderly especially when BMI is unavailable
