Abstract：
The Mediterranean Region registers an increasing prevalence of obesity. The region lacks a diet screener to assess obesogenic nutrients. This study aimed to evaluate the reproducibility and validity of the Modified Mediterranean Prime Screen (MMPS) in estimating obesogenic nutrients\' intake among women of reproductive age, as compared with a culturally validated Food Frequency Questionnaire (FFQ), in Lebanon. We developed the MMPS consisting of thirty-two food/beverage items specific to the Lebanese Mediterranean culture. The MMPS and FFQ were administered in two visits (2 weeks-6 months apart), face to face and via telephone during the coronavirus disease 2019 pandemic. The reproducibility and validity of the MMPS were assessed using intraclass correlation coefficients (ICC) and Pearson\'s correlations, respectively. The study included 143 women, aged 31·5 (sd 4·6) years, BMI 24·2 (sd 4·0) kg/m2, 87 % with university education and 91 % food secure. The reproducibility of the MMPS was moderate for energy and all assessed nutrients except for SFA (ICC = 0·428). The agreement of the MMPS with the reference FFQ was adequate for energy and obesogenic nutrients. Yet, the Pearson correlations for energy-adjusted nutrient intake were low for trans-fatty acids (0·294) and PUFA (0·377). The MMPS can be a time-efficient tool for dietary assessment of energy and many obesogenic nutrients. Future studies should validate the MMPS across the lifespan and re-evaluate it after updating the fatty acid profiles in the culturally specific food composition tables.
摘要：
地中海地区的肥胖患病率越来越高。该地区缺乏饮食筛选器来评估致胖营养素。本研究旨在评估改良地中海PrimeScreen（MMPS）在估计育龄妇女中的肥胖营养素摄入量方面的可重复性和有效性，与文化验证的食物频率问卷(FFQ)相比，在黎巴嫩。我们开发了由32种黎巴嫩地中海文化特有的食品/饮料组成的MMPS。在两次访问中（间隔2周-6个月）给予MMPS和FFQ，面对面,在COVID大流行期间通过电话。使用组内相关系数(ICC)和皮尔逊相关性评估了MMPS的可重复性和有效性，分别。这项研究包括143名女性，年龄：31.5±4.6岁，身体质量指数24.2±4.0Kg/m2，大学教育的87%，91%的食品安全。除了饱和脂肪酸(ICC=0.428)之外,MMPS对于能量和所有评估的营养素的再现性都是中等的。MMPS与参考FFQ的一致性对于能量和生性营养素是足够的。然而，反式脂肪酸(0.294)和多不饱和脂肪酸(0.377)与能量调节营养素摄入的Pearson相关性较低.MMPS可以是用于能量和许多致胖营养素的饮食评估的时间有效的工具。未来的研究应该在整个生命周期中验证MMPS，并在更新文化特定食物组成表中的脂肪酸谱后对其进行重新评估。
