Possible effects of a free school meal on school environment : The School Meal Intervention in Norway

Evidence suggests that a free school meal can improve children and adolescent diet, social environment, concentration, and school performance. This study aimed to investigate possible effects of a free, healthy school meal among students that usually eat packed meals on behavioral issues, inactiveness, self-efficacy, school enjoyment and classroom environment. A school meal according to the dietary guidelines was served to students in the intervention group (n=55) for one year. A control group consumed packed meals as usual (n=109). Students (10-12 years) responded to a questionnaire at baseline and after one year. We used linear regression analyses and did not find significant effects of a free school meal on behavioral issues (B= 0.01, p 0.86), inactiveness (B= -0.05, p 0.51), self - efficacy (B= -0.04, p 0.52), school enjoyment (B= 0.11, p 0.19) or classroom environment (B= -0.07, p 0.26). Methodological limitations might explain our lack of findings.publishedVersio
