【摘要】 目的：了解我国学龄儿童营养素养现况及其相关因素，为学龄儿童营养素养提升行动提供数据支持。方法：在2022年4月—2024年8月期间，采用方便抽样的方法对来自我国27个省（区、市）的14 312名3～9年级的学龄儿童开展线上调查，使用《学龄儿童营养素养问卷》收集调查对象的基本信息及营养素养数据。为便于进行组间比较，营养素养得分均折算为百分制。将折算后营养素养得分≥80分定义为“具备营养素养”。采用Wilcoxon秩和检验、Kruskal-Wallis检验、偏相关分析、卡方检验对数据进行统计学分析。结果：参与本调查的学龄儿童营养素养得分中位数为65.4(IQR=13.3)，仅6.7%的调查对象具备营养素养。女生中具备营养素养的比例高于男生，小学生高于初中生，组间差异均有统计学意义（P值均<0.05）。调查对象食物营养相关知识理念得分与技能各维度得分均呈正相关（r=0.418～0.592,P<0.05）。学龄儿童营养素养20条核心信息中，调查对象掌握率不足15%的有6条。结论：参与本调查的学龄儿童营养素养水平较低，性别和年级是其重要的影响因素，有必要开展针对性的食物营养教育，促进儿童营养素养提升。更多还原

【Abstract】 【Objective】To comprehensively analyze the current status and associated factors of nutrition literacy among school-age children in China, and to provide robust data support for enhancing the nutrition literacy of this demographic.【Method】From April 2022 to August 2024, a convenient sampling method was employed to conduct an online survey of 14 312 school-aged children from grades 3 to 9 across 27 provinces, municipalities, and autonomous regions in China. The basic information and nutrition literacy data was collected using the Food and Nutrition Literacy Questionnaire for Chinese School-age Children(FNLQ-SC). The full score of the questionnaire was converted into a percentage system, and the nutrition literacy score ≥80 points after conversion was defined as "having nutrition literacy". Wilcoxon rank sum test, Kruskal-Wallis test, partial correlation analysis and Chi-square test were used for statistical analysis.【Result】The median score of the nutrition literacy of the participants was 65. 4(IQR=13. 3), and only 6. 7% of them had nutrition literacy. The proportion with nutrition literacy was higher in girls than in boys, higher in primary school students than in junior high school students, with statistical significance among different groups(P<0. 05). The scores of participants on food nutrition related knowledge and concepts were positively correlated with scores of each dimension of skills(r=0. 418～0. 592, P<0. 05). Among the 20 core messages on nutrition literacy for school-aged children, there are 6 messages that less than 15% of the surveyed subjects have mastered.【Conclusion】The nutrition literacy level of school-aged children participating in this survey was low, and gender and grade are important influencing factors. It is necessary to carry out targeted food nutrition education to promote the improvement of children’s nutrition literacy.更多还原
