Abstract：
The Mediterranean diet (MD) and Western diet (WD) are poles apart as dietary patterns. Despite the availability of epidemiological tools to estimate the adherence to MD, to date, there is a lack of combined scores. We developed MEDOC, a food frequency questionnaire (FFQ) designed to calculate a combined adherence score for both diets and validated it on 213 subjects. The test-retest reliability revealed all frequency questions falling within the acceptable range of 0.5 to 0.7 (Pearson correlation coefficient) in younger (<30 years old) subjects, while 1 question out of 39 fell below the range in older (>30 years old) participants. The reproducibility for portion size was less satisfying, with, respectively, 38.2% and 70.5% of questions falling below 0.5 (Cohen\'s Kappa index) for younger and older subjects. The good correlation (R = 0.63, p < 0.0001 for subjects younger than 30 years and R = 0.54, p < 0.0001 for subjects older than 30 years, Pearson\'s correlation coefficient) between the MEDOC score and the MediDietScore (MDS) confirmed the validity of the MEDOC score in identifying patients who adhere to the MD. Harnessing the capabilities of this innovative tool, we aim to broaden the existing perspective to study complex dietary patterns in nutritional epidemiology studies.
摘要：
地中海饮食（MD）和西方饮食（WD）在饮食模式上截然不同。尽管有流行病学工具来估计MD的依从性，到目前为止,缺乏综合分数。我们开发了MEDOC,食物频率问卷（FFQ）旨在计算两种饮食的综合依从性得分，并对213名受试者进行了验证。重测信度显示，年轻（<30岁）受试者的所有频率问题均在0.5至0.7（皮尔逊相关系数）的可接受范围内，而39个问题中有1个问题低于年龄较大(>30岁)的参与者的范围。份量的可重复性不太令人满意，with,分别,38.2％和70.5％的问题低于0.5（科恩的Kappa指数）为年轻和老年科目。良好的相关性（R=0.63，p<0.0001对于30岁以下的受试者和R=0.54，p<0.0001对于30岁以上的受试者，MEDOC评分与MediDietScore（MDS）之间的Pearson相关系数）证实了MEDOC评分在识别坚持MD的患者中的有效性。利用这个创新工具的功能，我们的目标是扩大现有的观点，以研究营养流行病学研究中的复杂饮食模式。
