Dietary indices are useful measures to investigate associations between dietary intake and disease development. The Dutch Healthy Diet index 2015 (DHD2015-index), a measure of diet quality, assesses adherence to the 2015 Dutch dietary guidelines. We assessed the DHD2015-index in the Lifelines cohort study, and compared calculations from basic and detailed dietary intake data. This article replaces the retracted article that was published on 16 May 2022 [1].
Dietary intake was assessed with a specially developed Food Frequency Questionnaire (FFQ) called Flower-FFQ, which consists of one main questionnaire (heart-FFQ), which asks for intakes of major food groups, and three complementary questionnaires (petal-FFQs), which ask for detailed information on food types within major food groups of the heart-FFQ. The DHD2015-index was assessed using data from the total Flower-FFQ (for 56,982 participants), and using data from the heart-FFQ only (for 129,030 participants). Agreement between the two indices was assessed with correlation and cross-classification.
The median (25th-75th percentile) DHD2015-index score was 75 (65-85) for men and 81 (70-91) for women based on the Flower-FFQ, and 68 (58-77) for men and 73 (63-82) for women based on the heart-FFQ. The Kendall's tau-b correlation coefficient between the two scores was 0.67 for men and 0.66 for women. Cross-classification into quartiles of the DHD2015-index showed that 59-60% of participants were classified in the same quartile, 36-37% in the adjacent, and 4% in the non-adjacent.
Dietary data from the Flower-FFQ provide the most optimal information to assess the DHD2015-index. However, the DHD2015-index from the heart-FFQ showed good agreement with the index from the Flower-FFQ of ranking participants according to diet quality, and can be used when the DHD2015 index from the Flower-FFQ is not available.
饮食指数是研究饮食摄入与疾病发展之间关联的有用指标。荷兰健康饮食指数2015（DHD2015指数）是一种饮食质量衡量指标，用于评估对2015年荷兰饮食指南的遵循情况。我们在生命线队列研究中评估了DHD2015指数，并比较了基于基本和详细饮食摄入数据的计算结果。本文取代了2022年5月16日发表的撤回文章[1]。
饮食摄入通过一份专门开发的名为Flower-FFQ的食物频率问卷（FFQ）进行评估，该问卷由一份主要问卷（心脏-FFQ）组成，询问主要食物组的摄入量，以及三份补充问卷（花瓣-FFQ），询问心脏-FFQ主要食物组内食物类型的详细信息。使用来自整个Flower-FFQ的数据（针对56982名参与者）和仅来自心脏-FFQ的数据（针对129030名参与者）评估DHD2015指数。通过相关性和交叉分类评估两个指数之间的一致性。
基于Flower-FFQ，男性的DHD2015指数中位数（第25-75百分位数）为75（65-85），女性为81（70-91）；基于心脏-FFQ，男性为68（58-77），女性为73（63-82）。两个分数之间的肯德尔tau-b相关系数男性为0.67，女性为0.66。将DHD2015指数分为四分位数的交叉分类显示，59-60%的参与者被归为同一四分位数，36-37%在相邻四分位数，4%在非相邻四分位数。
来自Flower-FFQ的饮食数据为评估DHD2015指数提供了最优化的信息。然而，来自心脏-FFQ的DHD2015指数在根据饮食质量对参与者进行排名方面与来自Flower-FFQ的指数显示出良好的一致性，并且在无法获得来自Flower-FFQ的DHD2015指数时可以使用。
