title: Mini Nutritional Assessment (MNA) is Rather a Reliable and Valid Instrument to Assess Nutritional Status in Iranian Healthy Adults and Elderly with a Chronic Disease.
abstract: This study aimed to evaluate the usefulness of the Mini Nutritional Assessment (MNA) to assess nutritional status of Iranian population and to compare its psychometric properties between patients suffering from a chronic disease, healthy elderly and younger adults. As a group of elderly with a chronic disease, 143 Parkinson's disease (PD) patients and as the control group, 467 healthy persons were enrolled. The Persian-translated version of MNA was filled-up through interviews together with anthropometric measurements. Cronbach's α coefficient of entire MNA was 0.66 and 0.70 in healthy individuals and PD patients, respectively. The total MNA score could significantly discriminate the ones with BMI ≥ 24kg/m(2) in both groups. In general, MNA was a valid and reliable tool for nutritional assessment. We acknowledge study limitations including lack of serum measurements and a selection bias towards mild-to-moderate PD. MNA is a more reliable tool in older healthy individuals and rather younger elderly with PD.
