In the Netherlands, various FFQs have been administered in large cohort studies, which hampers comparison and pooling of dietary data. The present study aimed to describe the development of a standardized Dutch FFQ, FFQ-NL1.0, and assess its compatibility with existing Dutch FFQs.
Dutch FFQTOOLTM was used to develop the FFQ-NL1.0 by selecting food items with the largest contributions to total intake and explained variance in intake of energy and thirty-nine nutrients in adults aged 25-69 years from the Dutch National Food Consumption Survey (DNFCS) 2007-2010. Compatibility with the Maastricht-FFQ, Wageningen-FFQ and EPICNL-FFQ was assessed by comparing the number of food items, the covered energy and nutrient intake, and the covered variance in intake.
FFQ-NL1.0 comprised 160 food items, v. 253, 183 and 154 food items for the Maastricht-FFQ, Wageningen-FFQ and EPICNL-FFQ, respectively. FFQ-NL1.0 covered ≥85 % of energy and all nutrients reported in the DNFCS. Covered variance in intake ranged from 57 to 99 % for energy and macronutrients, and from 45 to 93 % for micronutrients. Differences between FFQ-NL1.0 and the other FFQs in covered nutrient intake and covered variance in intake were <5 % for energy and all macronutrients. For micronutrients, differences between FFQ-NL and other FFQs in covered level of intake were <15 %, but differences in covered variance were much larger, the maximum difference being 36 %.
The FFQ-NL1.0 was compatible with other FFQs regarding energy and macronutrient intake. However, compatibility for covered variance of intake was limited for some of the micronutrients. If implemented in existing cohorts, it is advised to administer the old and the new FFQ in combination to derive calibration factors.
在荷兰，多项 FFQ 已应用于大型队列研究，这妨碍了膳食数据的比较和汇总。本研究旨在描述标准化荷兰 FFQ（FFQ-NL1.0）的开发，并评估其与现有的荷兰 FFQ 的兼容性。
使用 Dutch FFQTOOLTM 通过选择对成年人总摄入量和能量及 39 种营养素摄入量解释方差贡献最大的食物项目，从 2007-2010 年荷兰国家食品消费调查（DNFCS）中开发 FFQ-NL1.0。通过比较食物项目数量、涵盖的能量和营养素摄入量以及摄入量解释方差，评估与马斯特里赫特 FFQ、瓦赫宁恩 FFQ 和 EPICNL-FFQ 的兼容性。
FFQ-NL1.0 包括 160 种食物项目，而马斯特里赫特 FFQ、瓦赫宁恩 FFQ 和 EPICNL-FFQ 分别包括 253、183 和 154 种食物项目。FFQ-NL1.0 涵盖 DNFCS 报告的≥85%的能量和所有营养素。涵盖的能量和宏量营养素摄入量的解释方差范围为 57%至 99%，微量营养素的摄入量解释方差范围为 45%至 93%。FFQ-NL1.0 与其他 FFQ 之间的能量和所有宏量营养素的营养素摄入量和摄入量解释方差的差异<5%。对于微量营养素，FFQ-NL1.0 与其他 FFQ 之间的覆盖水平差异<15%，但覆盖方差的差异要大得多，最大差异为 36%。
FFQ-NL1.0 在能量和宏量营养素摄入量方面与其他 FFQ 兼容。然而，对于一些微量营养素，摄入量解释方差的覆盖范围有限。如果在现有队列中实施，建议结合使用新旧 FFQ 来得出校准因子。
