We aimed to investigate the appropriateness of the Mini Nutritional Assessment (MNA) in predicting functional ability in older adults. Cross-sectional study. Participants were recruited from the Kahrizak Charity Foundation (KCF). Nutritional and ability status were examined using the MNA and the Barthel Index (BI). Participants were divided according to MNA (a parts per thousand currency sign23.5 and > 23.5). Two hundred and thirty-five a parts per thousand yen 60-year-old subjects were studied. The MNA and BI were positively correlated (r = 0.199; P = 0.001). The optimal cut-off point for BI with the highest sensitivity and specificity derived from the ROC curve was approximately 91.5 for males and 83.5 for females. The BI was significantly associated with MNA (odds ratio (OR): 1.89; 95% CI: 1.17-3.05, P = 0.009), mobility (OR: 6.39; 95% CI: 3.43-11.89, P < 0.001), consuming a parts per thousand yen 2 servings of fruit and vegetables (OR: 2.27; 95% CI: 1.09-4.72, P = 0.02) and self-view of nutritional status (OR: 4.15; 95%CI: 1.26-13.63, P = 0.01). The sensitivity (62.9% in males; 68.2% in females) and specificity (51.4% in males and 52.9% in females) of these cut-off points justifies the appropriateness of the MNA for determining functional ability. The MNA is potentially able to verify functional status among the elderly (as BI a parts per thousand yen 91.5 with those of < 91.5 in males and a parts per thousand yen 83.5 with those of < 83.5 in females) of KCF. It is suggested that this relationship should be further studied in a larger prospective population-based study.
