这项研究在来自希腊(GR)、葡萄牙(PT)、意大利(IT)、西班牙(SP)、塞浦路斯(CY)、北马其顿(NMK)和保加利亚(BG)的成年人中全面验证了14项地中海饮食坚持筛查(14-MeDAS)。在整个人群中,14-MEDAS与参考食物日记之间的相关性估计为中等(皮尔逊r=0.573,p值和t;0.001;组内相关系数=0.692,p值和t;0.001),其中GR的相关性最强,其次是PT、IT、SP和CY。这些结果得到了GR、PT、IT和SP的kappa统计数据的支持,其中50%的食品≥表现出较好或较好的一致性。Bland-Altman分析显示,在整个人群中高估了14-MeDAS评分(0.79±1.81,95%可信区间(CI)0.61,0.96),但这个值在不同国家之间是不同的,GR、NMK和BG表现出最低的偏差。综合所有分析,地中海国家的验证取得了略好的结果,但没有明确的验证排名顺序。考虑到越来越多的证据表明地中海饮食(MD)遵守的转变以及文化在食品选择中的重要性,我们必须进一步改进验证方案,并具体应用于衡量和比较各国对MD的遵守情况,并将其与特定人群的健康状况联系起来。
This study provides comprehensive validation of the 14-item Mediterranean Diet Adherence Screener (14-MEDAS) in an adult population from Greece (GR), Portugal (PT), Italy (IT), Spain (SP), Cyprus (CY), Republic of North Macedonia (NMK), and Bulgaria (BG). A moderate association between the 14-MEDAS and the reference food diary was estimated for the entire population (Pearson r = 0.573, p-value < 0.001; Intraclass Correlation Coefficient (ICC) = 0.692, p-value < 0.001) with the strongest correlation found in GR, followed by PT, IT, SP, and CY. These results were supported by kappa statistics in GR, PT, IT, and SP with ≥50% of food items exhibiting a fair or better agreement. Bland–Altman analyses showed an overestimation of the 14-MEDAS score in the whole population (0.79 ± 1.81, 95%Confidence Interval (CI) 0.61, 0.96), but this value was variable across countries, with GR, NMK, and BG exhibiting the lowest bias. Taking all analyses together, the validation achieved slightly better results in the Mediterranean countries but a definitive validation ranking order was not evident. Considering growing evidence of the shift from Mediterranean Diet (MD) adherence and of the importance of culture in making food choices it is crucial that we further improve validation protocols with specific applications to measure and compare MD adherence across countries and to relate it to the health status of a specific population.
