AbstractObjectiveAn increasing focus on legislation, policy and guidance on the nutritional content of school food has in part been in response to the limited impact of more behavioural or educational approaches. However, there is a risk that a sole focus on policy-level action may lead to neglect of the important contribution that more behavioural approaches can make as components of effective, coordinated, multilevel action to improve the dietary intake of schoolchildren. The current paper aims to highlight the potential importance of viewing alternative approaches as complementary or synergistic, rather than competing.DesignThe socio-ecological and RE-AIM frameworks are used to provide a theoretical rationale and demonstrate the importance of explicitly identifying the interdependence of policies, interventions and contextual structures and processes. School food case study evidence is used to exemplify how understanding and exploiting these interdependencies can maximise impact on dietary outcomes.SettingCase studies of trials in schools in the UK (South West England and Wales) and Australia (Victoria).SubjectsSchoolchildren.ResultsThe case studies provide examples to support the hypothesis that the reach, effectiveness, adoption, implementation and maintenance of school food policies and interventions can be maximised by understanding and exploiting the interdependence between levels in the socio-ecological framework.ConclusionsRather than being seen as competing alternatives, diverse approaches to improving the diets of schoolchildren should be considered in terms of their potential to be complementary and synergistic, acting at multiple levels to improve acceptability, fidelity, effectiveness and sustainability.
