Development and Validation of the Vietnamese Children Short Dietary Questionnaire

This dataset was used to examine the reproducibility and validity of the Vietnamese Children's Short Dietary Questionnaire (VCSDQ) in children 9-11 years old in urban Vietnam. The data was collected in July and Sep-Oct 2019 n Ho Chi Minh City, Vietnam.

This study aims to develop and assess the reproducibility and validity of the Vietnamese Children’s Short Dietary Questionnaire (VCSDQ) in evaluating food groups intakes and dietary practices among school-aged children 9–11 years old in urban Vietnam. A 26-item questionnaire covering frequency intakes of five core food groups, five non-core food groups, five dietary practices over a week, and daily intakes of fruits, vegetables, and water was developed. Children (n = 144) from four primary schools in four areas of Ho Chi Minh City, Vietnam completed the VCSDQ twice, as well as three consecutive 24 h recalls over a week. Intra-class correlation, Spearman correlation, weighted kappa, cross-classification, and Bland–Altman plots were used to evaluate the reproducibility and validity. The direct validity of food groups from VCSDQ against the 24 h recalls was examined using Wilcoxon-test for trend. The VCSDQ had good reproducibility in 12 out of 15 group items; the ICC ranged from 0.33 (grains) to 0.84 (eating while watching screens). This VCSDQ had low relative validity, two items (instant noodles, eating while watching screens) had a moderate to good agreement (k = 0.43, k = 0.84). There was good direct validity in three core-food groups (fruits, vegetables, dairy) and three non-core food groups (sweetened beverages, instant noodles, processed meat). In addition, the VCSDQ can also be used to classify daily intakes of fruits and vegetables from low to high.

本数据集旨在审视越南儿童短膳食问卷（VCSDQ）在越南城市9至11岁儿童群体中的可重复性和有效性。数据采集于2019年7月至9月，在越南胡志明市进行。研究旨在开发并评估VCSDQ在评估城市越南学龄儿童（9至11岁）食物摄入量和饮食习惯方面的可重复性和有效性。问卷包含26个项目，涵盖了五类核心食物摄入频率、五类非核心食物摄入频率、一周内的五种饮食习惯以及水果、蔬菜和水的每日摄入量。来自胡志明市四个区域的四所小学的144名儿童完成了两次VCSDQ，以及一周内的连续三次24小时回顾。使用组内相关系数、Spearman相关系数、加权Kappa值、交叉分类和Bland-Altman图来评估可重复性和有效性。通过Wilcoxon趋势检验，考察了VCSDQ中食物摄入组与24小时回顾的直接有效性。VCSDQ在15个组别中的12个表现出了良好的可重复性；组内相关系数（ICC）范围从0.33（谷物）至0.84（观看屏幕时进食）。本VCSDQ的相对有效性较低，其中两项（方便面、观看屏幕时进食）表现出中到好的符合度（Kappa值为0.43和0.84）。在三个核心食物组（水果、蔬菜、乳制品）和三个非核心食物组（含糖饮料、方便面、加工肉类）中，表现出了良好的直接有效性。此外，VCSDQ还可以用于从低到高对每日水果和蔬菜的摄入量进行分类。数据所有者愿意感谢其导师A.
