目的：研究免费学校午餐服务是否对初中学生体重发展和食物摄入产生影响，并评估自我感知学校行为与食物摄入之间的关系。设计：2007年1月至5月，一项为期4个月的对照干预研究涉及为九年级学生提供免费健康的学校午餐。在干预前后分别测量体重和身高。学生们还完成了一份简短的FFQ和一份关于干预前后自我感知的学校行为和课堂环境的问卷。使用FFQ数据计算健康食品评分。背景：挪威南部三所不同初中的所有九年级学生被邀请参加。随机选择一所学校作为干预学校。受试者：干预学校58名学生（91%）和对照学校92名学生（77%）参加。结果：干预学校女生的体重指数没有增加，而干预学校男生和对照组的体重指数明显增加。健康食品得分与“学业满意”正相关（p < 0.001）。15%的食物得分差异可以用性别和“学业满意”这一特征来解释。结论：为中学生提供健康的免费学校午餐可能会导致体重增加受到限制。需要进一步的研究来阐明学校膳食对超重和学习成绩的影响。
Objective: To study whether service of a free school lunch has an impact on weight development and food intake among pupils at a lower secondary school, and to assess the association between self-perceived school behaviour and food intake.Design: A controlled intervention study involving service of a free healthy school lunch to 9th grade pupils took place over 4 months, from January to May 2007. Weight and height were measured before and after the intervention. The pupils also completed a short FFQ and a questionnaire concerning self-perceived school behaviour and the classroom environment before and after the intervention. A healthy food score was calculated using the FFQ data.Setting: All 9th graders at three different lower secondary schools in southern Norway were invited to participate. One school was randomly selected as the intervention school.Subjects: Fifty-eight pupils (91%) from the intervention school and ninety-two pupils (77%) from the control schools participated.Results: BMI did not increase among the girls at the intervention school, but increased significantly among the boys at the intervention school and among the control school groups. The healthy food score correlated positively with the trait 'satisfied with schoolwork' (p < 0.001). fifteen per cent of the variance in food score could be explained by gender and the trait 'satisfied with schoolwork'Conclusions: Serving of a healthy free school lunch to secondary-school pupils may result in restricted weight gain. Further studies are needed to clarify the impact of school meals on overweight and academic performance.
