A Mediterranean style dietary pattern (MDP) is considered beneficial for health. The MD Score (MDS) definition has evolved, resulting in considerable variability in the foods and nutrients associated with MDS adherence. We systematically investigated food and nutrient composition of the MD between studies, countries, and methods of classifying the MDS. We searched Embase for MD systematic reviews and selected observational studies reporting intakes of foods, macronutrients, or micronutrients by categories of MDS adherence. The percentage differences in food and nutrient intakes between categories of high and low adherence to the MDS were calculated for each study. A total of 369 full‐text primary papers were reviewed from the included systematic reviews and 74 papers selected (66 adults, 8 children). We found considerable differences in MDS definitions and scoring criteria. Between‐study variation in food intake between high‐ and low‐adherence MDS adherence categories ranged from a mean of −23% for meat, to 119% for fruit, and 278% for fish. Greater variability was evident in non‐Mediterranean than Mediterranean regions. We conclude that few studies report food and nutrient intakes across the range of the MDP in adults and even fewer in children. The considerable variability in the foods and nutrients reported makes comparison of results from studies and translation into dietary guidelines difficult. We recommend that future publications of MD studies include full details of the range of food and nutrient intakes across the distribution of MD adherence in order to facilitate translation into health policy and practice.

地中海饮食模式中食物和营养摄入量存在很大差异——系统评价



地中海式饮食模式(MDP)被认为对健康有益。 MD 评分 (MDS) 定义不断演变,导致与 MDS 依从性相关的食物和营养素存在相当大的变化。我们系统地研究了不同研究、国家和 MDS 分类方法之间的 MD 食物和营养成分。我们在 Embase 上搜索了 MD 系统评价,并选择了按 MDS 依从性类别报告食物、常量营养素或微量营养素摄入量的观察性研究。每项研究都计算了 MDS 高依从性和低依从性类别之间食物和营养摄入量的百分比差异。从纳入的系统评价中总共对 369 篇全文初级论文进行了综述,并选出了 74 篇论文(66 名成人,8 名儿童)。我们发现 MDS 定义和评分标准存在很大差异。高依从性和低依从性 MDS 依从性类别之间食物摄入量的研究间差异范围为肉类的平均值为 -23%,水果的平均值为 119%,鱼类的平均值为 278%。与地中海地区相比,非地中海地区的变异性更大。我们的结论是,很少有研究报告成人在 MDP 范围内的食物和营养摄入量,而儿童的研究则更少。所报道的食物和营养素的巨大差异使得研究结果的比较和转化为膳食指南变得困难。我们建议未来的医学博士研究出版物包括关于医学博士依从性分布的食物和营养摄入范围的完整细节,以促进转化为卫生政策和实践。
