The levels of evidence supporting the recommendations (Ia, Ib, IIa, IIb, III, IV) are defined at the end of the "Major Recommendations" field.
The following recommendations are organized according to the ecological framework described on page 20 in the original guideline document and are not presented in order of priority. Rather, general recommendations are followed by those directed at the community, school, family, and individual, in that order. Practice recommendations are then followed by recommendations related to nursing education and organizational/policy development.
There is limited evidence on the effectiveness of obesity prevention interventions in children. Despite the lack of evidence around obesity prevention, the development panel reviewed high quality evidence around behavioural change in relation to healthy eating and physical activity as a starting point for the prevention of childhood obesity. Through consensus, the development panel reached the decision to identify specific recommendations with an embedded behavioural change component as high level of evidence (e.g., Ia-IIb). Where the level of evidence in the table below is identified as high level (e.g., Ia-IIb), this indicates that a high level exists for behavioural change, however the extrapolation for obesity prevention in children is consensus-based (e.g., Level IV).

Nurses assist clients to access community resources and opportunities to engage in healthy eating and physical activity through:
- Direct referral of clients to community resources
- Dissemination of information about available community resources

- Population health promotion and prevention principles and interventions aimed at:
- Health promoting behaviours such as physical activity and healthy eating
- Obesity prevention
- Chronic disease prevention
- Determinants of health (particularly as they impact the risks for obesity and chronic diseases)

Organization & Policy Recommendations
Recommendation 16.0
Nurses advocate for, and participate in, high quality research addressing identified knowledge gaps in the prevention of childhood obesity.
(Level of Evidence = IV)
Recommendation 17.0
Nurses advocate for organizations to develop a plan for implementation that is evidence-based and includes:
- An assessment of organizational readiness and barriers to education
- Involvement of all stakeholders (whether in a direct or indirect supportive function) who will contribute to the implementation process

- An organizational culture that is supportive of evidence-based practice
- Evaluation of effectiveness
In this regard, RNAO (through a panel of nurses, researchers and administrators) has developed the Toolkit: Implementation of Clinical Practice Guidelines based on available evidence, theoretical perspectives, and consensus. The Toolkit is recommended for guiding the implementation of the RNAO guideline Primary Prevention of Childhood Obesity.
