Abstract

Background

Current dietary assessment methods are affected by memory-related bias and heavily burden respondents. To reduce respondent burden and associated measurement error, we recently developed an innovative smartphone-based 2-h recall (2hR) method.

Objectives

Evaluation of the use of random 2hRs, administered via the smartphone-based dietary assessment tool “Traqq”, for assessing habitual intake against a validated food frequency questionnaire (FFQ) and blood concentration markers.

Methods

Dietary intake was assessed in 215 Dutch adults by repeated 2hRs on randomly selected days and times (i.e. equivalent to 3 full days of 2hRs) over a 4-wk period. At the end of the study period, participants completed a validated semiquantitative FFQ. Sixty-five random participants also provided 2 fasting blood samples, to assess plasma carotenoid and plasma n-3 polyunsaturated fatty acid (PUFA) concentrations.

Results

Intake estimates of energy (2132 ± 665 kcal vs. 2017 ± 572 kcal) were slightly higher with 2hRs than FFQ, whereas the percentage energy intake from macronutrients where similar (i.e. protein: 37 ± 14 en% vs. 37 ± 13 en%; fat: 35 ± 6 en% vs. 44 ± 7 en%; carbohydrates: 44 ± 7 en% vs. 44 ± 6 en%). For food groups, a larger variation in intake estimates was found ranging from –65% (legumes) to 62% (pastry, cake and biscuits). Spearman correlations between 2hRs and FFQ ranged from 0.33 to 0.69 for energy and macronutrients, from 0.32 to 0.58 for micronutrients, and from 0.27 to 0.67 for food groups. For all nutrients and food groups, ≥70% of the participants were classified in the same/adjacent quartile. Spearman correlations between 2hRs and plasma carotenoids and n-3 PUFA ranged between 0.34 and 0.57 and cross-classification ranged between 61% and 83% in the same/adjacent quartile.

Conclusions

Comparing 2hRs with FFQ and blood concentration markers showed good ranking ability for energy, most nutrients, and most frequently consumed foods. More variation was seen for episodically consumed foods and nutrients.

Trial registration number

This trial was registered at the Dutch Central Committee on Research Involving Human Subjects (CCMO) registry as ABR No. NL69065.081.19 (https://www.toetsingonline.nl/to/ccmo_search.nsf/fABRpop?readform&unids=26E81F6A56186B1EC12587BD001C7AC9).

基于智能手机的饮食评估工具“Traqq”通过随机2小时回忆来评估成年人的习惯性饮食摄入量：与食物频率问卷和血液浓度生物标志物的比较

背景：目前的饮食评估方法受到记忆相关偏差的影响，给被调查者带来了沉重的负担。为了减少被调查者的负担和相关的测量误差，我们最近开发了一种创新的基于智能手机的2小时召回（2hR）方法。目的：通过基于智能手机的饮食评估工具“Traqq”评估随机2hr的使用情况，以评估习惯性摄入量与经过验证的FFQ和血液浓度标记物之间的关系。方法：在四周的时间里，通过随机选择的日期和时间（即相当于整整三天的2小时）重复2小时的饮食摄入评估215名荷兰成年人。在研究期结束时，参与者完成了经过验证的半定量FFQ。65名随机参与者还提供了两份空腹血液样本，以评估血浆类胡萝卜素和血浆n-3 PUFA浓度。结果：两小时后的能量摄入估算值（2,132±665 kcal vs. 2,017±572 kcal）略高于FFQ，而从大量营养素中摄入的能量百分比相似(即蛋白质：37±14 % vs. 37±13 %；脂肪：35±6 % vs. 44±7 %；碳水化合物：44±7% vs. 44±6%)。对于食物组来说，摄入估计的差异更大，从-65%（豆类）到62%（糕点、蛋糕和饼干）不等。能量和宏量营养素组2hr与FFQ的Spearman相关性为0.33 ~ 0.69，微量营养素组0.32 ~ 0.58，食物组0.27 ~ 0.67。对于所有营养素和食物组，≥70%的参与者被归类为相同/相邻四分位数。2hRs与血浆类胡萝卜素和n-3 PUFA之间的Spearman相关性在0.34 ~ 0.57之间，交叉分类在相同/相邻四分位数之间为61% ~ 83%。结论：将2hRs与FFQ和血药浓度指标进行比较，对能量、大多数营养物质和最常食用的食物具有较好的排序能力。偶尔食用的食物和营养物质的变化更大。
