【 摘 要 】

ObjectiveTo 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.DesignA 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.SettingAll 9th graders at three different lower secondary schools in southern Norway were invited to participate. One school was randomly selected as the intervention school.SubjectsFifty-eight pupils (91 %) from the intervention school and ninety-two pupils (77 %) from the control schools participated.ResultsBMI 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’.ConclusionsServing 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.
