A dietary screener questionnaire (DSQ) was used to assess dietary outcomes among children in the Healthy Communities Study (HCS), a study of the relationships between programs and policies to prevent child obesity and child diet, physical activity and weight outcomes.
To compare dietary intake estimates derived from the DSQ against those from the Automated Self-Administered 24-Hour Recalls for Children (ASA24-Kids) among children, a measurement error model, using structural equation modelling, was utilized to estimate slopes, deattenuated correlation coefficients, and attenuation factors by age and sex, ethnicity, and BMI status.
PARTICIPANTS/SETTING: A randomly selected sub-sample of HCS participants aged 4-15 years in 130 communities throughout the U.S. who completed the DSQ and up to two ASA24-Kids recalls (n = 656;13% of HCS participants).
For most nutrient/foods examined, the DSQ yielded larger mean intake estimates than the ASA24-Kids, and agreement between the two measures varied by food/nutrient, age and sex, ethnicity, and BMI category. Deattenuated correlation coefficients of 0.4 or greater were observed for added sugars from SSBs (0.54), fruits and vegetables (0.40), and dairy foods (0.50). Lower deattenuated correlation coefficients were seen for total added sugars (0.37), whole grains (0.34), and fiber (0.34). Attenuation factors were most severe for total added sugars intake among overweight children, and for several other dietary outcomes among children aged 9-11 years.
The DSQ was found to be a tool with acceptable agreement with the ASA24-Kids for measuring multiple dietary outcomes of interest in the HCS, although there may be potential due to measurement error to underestimate results (bias towards the null). In future studies, measurement error modelling and regression calibration may be possible solutions to correct for bias due to measurement error in most food/nutrient intake estimates from the DSQ when used among children.
膳食筛选问卷 (DSQ) 用于评估健康社区研究 (HCS) 中儿童的膳食结果，该研究旨在研究预防儿童肥胖和儿童饮食、身体活动和体重结果的计划和政策之间的关系。
为了比较 DSQ 得出的膳食摄入量估计值与儿童自动自我管理 24 小时回忆 (ASA24-Kids) 之间的差异，使用结构方程模型，针对年龄和性别、族裔和 BMI 状态，建立了一个测量误差模型来估计斜率、去衰减相关系数和衰减因子。
参与者/设置：从美国 130 个社区中随机抽取 HCS 参与者的一个子样本，年龄在 4-15 岁之间，他们完成了 DSQ 并进行了最多两次 ASA24-Kids 回忆（n=656；HCS 参与者的 13%）。
对于大多数营养素/食物，DSQ 得出的平均摄入量估计值大于 ASA24-Kids，两种测量方法的一致性因食物/营养素、年龄和性别、族裔以及 BMI 类别而异。从 SSB 中添加的糖（0.54）、水果和蔬菜（0.40）以及奶制品（0.50）的去衰减相关系数为 0.4 或更高。总添加糖（0.37）、全谷物（0.34）和纤维（0.34）的去衰减相关系数较低。超重儿童的总添加糖摄入量以及 9-11 岁儿童的其他几种膳食结果的衰减因子最为严重。
DSQ 被发现是一种工具，与 HCS 中感兴趣的多种膳食结果的 ASA24-Kids 具有可接受的一致性，尽管由于测量误差，结果可能存在低估的可能性（偏向于零）。在未来的研究中，测量误差建模和回归校准可能是解决使用 DSQ 测量儿童中大多数食物/营养素摄入量估计值时由于测量误差导致的偏差的可行方法。
