To assess the effects of a school-based intervention on the diets of 7-9-year-olds.
Dietary intake of children in second and fourth grades was assessed with 3d weighed dietary records in autumn 2006 and autumn 2008, before and after a school-based intervention that started in the middle of second grade, and compared with control schools with no intervention. The diet was evaluated by comparison with food-based dietary guidelines (FBDG) and reference values for nutrient intake. The intervention aimed at several determinants of intake: knowledge, awareness, preferences/taste, self-efficacy and parental influence. Nutrition education material was developed for the intervention and implemented in collaboration with teachers. The main focus of the intervention was on fruit and vegetable intake as the children's intake was far from meeting the FBDG on fruit and vegetables at baseline.

Complete dietary records were available for 106 children both at baseline and follow-up.
Total fruit and vegetable intake increased by 47 % in the intervention schools (mean: 61.3 (sd 126.4) g/d) and decreased by 27 % in the control schools (mean: 46.5 (sd 105.3) g/d; P < 0.001). The majority of the children in the intervention schools did still not meet the FBDG on fruits and vegetables at follow-up. Fibre intake increased significantly in the intervention schools, as well as that of potassium, magnesium, beta-carotene and vitamin C (borderline).
The school-based intervention in 7-9-year-olds was effective in increasing fruit and vegetable intake, by 47 % increase from baseline, which was mirrored in nutrient intake.
评估一项基于学校的干预措施对 7-9 岁儿童饮食的影响。
在 2006 年和 2008 年秋季，在基于学校的干预措施开始于二年级中期之前和之后，使用 3 天称重饮食记录评估二年级和四年级儿童的饮食摄入量，并与没有干预的对照学校进行比较。通过与基于食物的饮食指南 (FBDG) 和营养素摄入量参考值进行比较来评估饮食。该干预措施旨在针对摄入的几个决定因素：知识、意识、偏好/口味、自我效能和父母影响。为干预措施开发了营养教育材料，并与教师合作实施。干预的主要重点是水果和蔬菜的摄入量，因为孩子们的摄入量远低于基线时 FBDG 对水果和蔬菜的建议。

在基线和随访时，106 名儿童均提供了完整的饮食记录。
干预学校的总水果和蔬菜摄入量增加了 47%（平均：61.3（126.4）g/d），对照组学校的摄入量减少了 27%（平均：46.5（105.3）g/d；P<0.001）。在随访时，干预学校的大多数儿童仍然没有达到 FBDG 对水果和蔬菜的建议量。干预学校的膳食纤维摄入量显著增加，钾、镁、β-胡萝卜素和维生素 C 的摄入量也有所增加（边缘增加）。
在 7-9 岁儿童中开展的基于学校的干预措施有效增加了水果和蔬菜的摄入量，与基线相比增加了 47%，这反映在营养素摄入量上。
