This study aims to estimate cost variations according to diet quality and sociodemographic characteristics in children. Data (n = 1,596; 5-17 y) from the were used. The "" and dietary patterns (DP) identified through principal component analysis were used to assess diet quality. Daily diet cost was estimated after linking the consumed foods with the food prices. The mean diet cost was 4.68€/day (SEM: 0.05). Adjusted for covariates and energy intake, the mean diet cost was 9.1% higher in the highest adherence (. the lowest) and 6.2% higher in the tercile T3 (. T1) of the "Healthy" DP score. It was 4.8% lower in the T3 (. T1) for the "Junk food" DP score. Diet cost was higher in 12-17 year-olds (. 5-11 years) and in medium and high educated household (. the lowest). These findings support policies to make healthy diets more affordable.
这项研究旨在根据儿童的饮食质量和社会人口特征来估计成本变化。使用了来自（n=1596；5-17 岁）的数据。通过主成分分析确定的“饮食质量指数”和饮食模式（DP）用于评估饮食质量。在将消耗的食物与食品价格进行链接后，估算了每日饮食成本。平均饮食成本为每天 4.68 欧元（SEM：0.05）。在调整了协变量和能量摄入后，“健康” DP 得分最高（最低）组的饮食成本平均高出 9.1%，而“垃圾食品” DP 得分第三组（T3）则高出 6.2%。在 DP 得分第三组（T3）中，饮食成本则降低了 4.8%。在 12-17 岁的儿童（5-11 岁）和中等和高等教育程度的家庭（最低）中，饮食成本更高。这些发现支持制定使健康饮食更负担得起的政策。
