摘要

背景：广泛用于老年人的营养评估工具包括迷你营养评估（MNA）和迷你营养评估-简式（MNA-SF）工具。这些工具尚未在埃塞俄比亚等发展中国家的老年人口中进行有效性和可靠性评估。本研究旨在评估小型营养评估工具的完整和简短形式在埃塞俄比亚老年人中的可靠性和有效性。方法：我们使用一项基于社区的横断面研究，在506名老年人中评估了工具的可靠性和有效性。评估准确性、敏感性、特异性和截止点，以确定完整MNA和MNA-SF工具的有效性。使用Cronbachα系数评估可靠性。通过计算MNA总分和人体测量之间的相关性来评估MNA工具的标准相关有效性。尤登指数用于确定完整MNA和MNA-SF的最佳分界点。结果：MNA平均得分为19.9 ± 4.5.完整MNA工具的Cronbachα值为0.7。全MNA的总体准确率为91%（95%CI，87.5%-94.9%）。使用既定截止点的全MNA工具的敏感性和特异性分别为87.9%和89.6%。Youden指数分析表明，使用全MNA检测营养不良和有营养不良风险者的最佳分界点为16（敏感性90.4%，特异性86.8%）。用Cronbachα测量的MNA-SF的可靠性为0.5。MNA-SF的总体准确率为93%（95%CI，0.90–0.96）。通过使用Youden指数，MNA-SF检测营养不良的最佳分界点为7.5（敏感性85.7%，特异性89%）。结论：完整的MNA工具是一个有效和可靠的工具，可以识别营养不良、有营养不良风险和营养良好的老年人，并通过调节分界点。然而，在本研究中，短MNA工具是有效的，但不可靠。

Validity of Mini Nutritional Assessment tool among an elderly population in Yeka sub-city, Addis Ababa, Ethiopia

Background: The widely used nutritional assessment tool used for the elderly includes the Mini Nutritional Assessment (MNA) and Mini Nutritional Assessment–Short Form (MNA-SF) tool. These tools have not been evaluated for their validity and reliability among the elderly population of developing countries such as Ethiopia. This study aimed to evaluate the reliability and validity of the full and short form of the Mini Nutritional Assessment tool among the elderly in Ethiopia. Method: We evaluated the reliability and validity of the tools using a community-based cross-sectional study among 506 elderly individuals. Accuracy, sensitivity, specificity and cut-off point were evaluated to determine the validity of both the full MNA and MNA-SF tool. Reliability was assessed using Cronbach’s α coefficient. The criterion-related validity of the MNA tool was evaluated by computing the correlation between the total MNA score and anthropometric measurements. The Youden index was used to determine best cut-off points of the full MNA and MNA-SF. Result: The mean MNA score was 19.9 ± 4.5. Cronbach’s α value of the full MNA tool was 0.7. The overall accuracy of the full MNA was 91% (95% CI, 87.5%–94.9%). The sensitivity and specificity of the full MNA tool using an established cut-off point was 87.9% and 89.6% respectively. Youden index analysis showed that the best cut-off point to detect the malnourished and those at risk of malnutrition using the full MNA was 16 (sensitivity 90.4% and specificity 86.8%). The reliability of the MNA-SF as measured by Cronbach’s α was 0.5. The overall accuracy of the MNA-SF was found to be 93% (95% CI, 0.90–0.96). By using the Youden index the best cut-off point for MNA-SF to detect malnutrition was 7.5 (sensitivity 85.7% and specificity 89%). Conclusion: The full MNA tool was a valid and reliable tool to identify elderly individuals who are malnourished, at risk of malnutrition and well-nourished with modulation of cut-off points. However, the short MNA tool was valid and but not reliable in this study.
