在健康社区研究（HCS）中，饮食筛查问卷（DSQ）被用来评估儿童的饮食结果，这是一项关于预防儿童肥胖的计划和政策与儿童饮食，身体活动和体重结果之间关系的研究。为了在儿童中比较来自DSQ的膳食摄入量估计值与来自儿童自动自我管理24小时召回（ASA 24-Kids）的膳食摄入量估计值，使用结构方程模型的测量误差模型，按年龄和性别、种族和BMI状态估计斜率、去衰减相关系数和衰减因子。在美国130个社区随机选择4-15岁的HCS参与者子样本，他们完成了DSQ和最多两次ASA 24-Kids回忆（n = 656;13%的HCS参与者）。对于检查的大多数营养素/食物，DSQ产生的平均摄入量估计值大于ASA 24-Kids，两种测量方法之间的一致性因食物/营养素、年龄和性别、种族和BMI类别而异。从SSB（0.54）、水果和蔬菜（0.40）和乳制品（0.50）中添加的糖观察到0.4或更大的去衰减相关系数。较低的衰减相关系数被认为是总添加糖（0.37），全谷物（0.34），和纤维（0.34）。在超重儿童中，总添加糖摄入量的衰减因素最严重，在9-11岁儿童中，其他几种饮食结果也是如此。DSQ被认为是一种与ASA 24-Kids具有可接受一致性的工具，用于测量HCS中感兴趣的多种饮食结局，尽管由于测量误差可能会低估结果（偏向零值）。在未来的研究中，测量误差建模和回归校准可能是纠正偏差的可能解决方案，因为DSQ在儿童中使用时，大多数食物/营养素摄入量估计值的测量误差。本文的在线版本（10.1186/s12937-018-0415-1）包含补充材料，可供授权用户使用。
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. 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.
