We conducted the umbrella review to identify systematic reviews and stakeholders’ documents. In general, systematic reviews and meta-analyses collate empirical evidence that fits pre-specified eligibility criteria, by using explicit, replicable, systematic search, extraction, and evaluation methods that are selected to minimize biases [17]. Umbrella reviews represent a way of synthesizing the evidence accumulated in systematic reviews and making them suitable for a more general audience of healthcare practitioners [18]-[20]. Although typical umbrella reviews focus on analyzing materials obtained from systematic reviews [17],[18], the aim of this study required integrating the evidence presented in reviews (both systematic and non-systematic position reviews) with practice recommendations issued by major stakeholders.
In order to elicit the good practice characteristics 3 types of documents were analyzed. First, we searched for systematic reviews analyzing characteristics of policies/interventions, and forming recommendations about these characteristics. Second, we searched for position papers that offered a comprehensive review of research evidence supporting good practice characteristics, but did not apply methods of systematic reviews. Finally, we searched for peer-reviewed and non-peer-reviewed documents, issued by major national and international stakeholders. We investigated documents aiming at eliciting evidence-based good practice criteria or providing practice recommendations for interventions/policies targeting healthy diet, physical activity, or sedentary behaviors
