本研究的目的是调查2-9岁欧洲儿童代理报告的能量摄入量、每日食物摄入量和食物能量密度与体重指数（BMI）z评分之间的关系。从16,225名参与儿童和婴儿饮食和生活方式引起的健康影响的识别和预防（IDEFICS）基线检查的儿童中，9名，782名具有24小时替代饮食信息和完整协变量信息的儿童被纳入分析。参与的儿童根据适应戈德堡截止值进行分类：低报，合理的能源报告和多报。计算所有进食场合的能量摄入量、每日食物摄入量和食物能量密度（不包括无热量饮料）。采用多水平回归模型研究了能量摄入、每日食物摄入量和食物能量密度对BMI z评分的影响。暴露变量被单独纳入;每日食物摄入量和能量摄入量在一个组合模型中进行处理，以检查相互作用。在合理的能量报告组（N = 8，544）中，能量摄入量和每日食物摄入量与BMI z评分显著正相关。食物的能量密度与BMI Z评分无关。在包括能量摄入、食物摄入和交互作用项的模型中，只有能量摄入对BMI z评分显示出显著的正效应。在完整样本（N = 9，782）中，只有能量摄入量与BMI z评分呈显着负相关。代理报告者容易出现误报，尤其是对于BMI水平较高的儿童。能量摄入是儿童不健康体重发展的更重要的预测因素，而不是每日食物摄入。
The aim of this study was to investigate the associations between proxy-reported energy intake, daily food intake and energy density of foods and body mass index (BMI) z-score in 2-9-year-old European children.From 16,225 children who participated in the identification and prevention of dietary- and lifestyle-induced health effects in children and infants (IDEFICS) baseline examination, 9,782 children with 24-h proxy dietary information and complete covariate information were included in the analysis. Participating children were classified according to adapted Goldberg cutoffs: underreports, plausible energy reports and overreports. Energy intake, daily food intake and energy density of foods excluding noncaloric beverages were calculated for all eating occasions. Effect of energy intake, daily food intake and energy density of foods on BMI z-score was investigated using multilevel regression models in the full sample and subsample of plausible energy reports. Exposure variables were included separately; daily food intake and energy intake were addressed in a combined model to check for interactions.In the group of plausible energy reports (N = 8,544), energy intake and daily food intake were significantly positively associated with BMI z-score. Energy density of foods was not associated with BMI z-score. In the model including energy intake, food intake and an interaction term, only energy intake showed a significantly positive effect on BMI z-score. In the full sample (N = 9,782), only energy intake was significantly but negatively associated with BMI z-score.Proxy-reporters are subject to misreporting, especially for children in the higher BMI levels. Energy intake is a more important predictor of unhealthy weight development in children than daily food intake.
