The Pan American Health Organization (PAHO) and the Organization of American States (OAS) have jointly launched new evidence-based guidelines designed to improve nutrition and increase physical activity in schools across the Americas. The initiative addresses rising childhood obesity and non-communicable disease prevalence in the region, with school-based interventions serving as a key public health lever.
Key takeaways
- PAHO and OAS released coordinated guidelines on school nutrition and physical activity targeting all member states in the Americas
- The guidelines emphasize comprehensive school health policies, including food standards and mandatory physical education
- Implementation aims to reduce childhood obesity and associated non-communicable diseases (NCDs) across the region

Coordinated Regional Response to Childhood Obesity
According to PAHO’s regional health assessments, childhood overweight and obesity rates have accelerated across Latin America and the Caribbean, with significant variation by country. The new guidelines represent a harmonized approach endorsed by both PAHO and the OAS, requiring member states to implement school-based interventions that address dietary patterns, physical activity levels, and structural barriers to healthy choices.
The guidelines establish minimum standards for school nutrition policies, including restrictions on ultra-processed foods and sugar-sweetened beverages, alongside requirements for at least 150 minutes of moderate-intensity physical activity per week for students, consistent with World Health Organization physical activity recommendations for children and adolescents.
Evidence-Based Components of the New Framework
The PAHO/OAS guidelines integrate findings from published research on school-based health interventions. Key recommendations include: (1) mandatory nutritional standards for foods sold in school cafeterias and vending machines; (2) integration of physical activity into the standard curriculum beyond physical education classes; (3) environmental modifications to schools (e.g., safe spaces for play, removal of marketing for unhealthy foods); and (4) professional development for educators to deliver health literacy and nutrition education.
According to the organisations’ joint announcement, the framework also addresses upstream determinants including socioeconomic barriers, food system policies, and agricultural subsidies that influence school food availability. This systems-level approach reflects current evidence on the limitations of individual-behaviour-change interventions without structural support, as documented in health policy research on non-communicable disease prevention.
School-based nutrition and physical activity programmes, when implemented with institutional commitment and teacher support, can reduce childhood obesity prevalence by an estimated 5–15% over 3–5 years, according to meta-analyses of regional intervention trials.

Implementation Pathways and Member State Accountability
PAHO and OAS have established timelines for member state adoption, with binding commitments to develop national action plans aligned with the guidelines. The organisations will provide technical assistance, training modules, and monitoring frameworks to track progress on key indicators: percentage of schools with compliant nutrition policies, student physical activity levels, and trends in childhood overweight and obesity prevalence.
Implementation will be monitored through existing PAHO health monitoring platforms, with regular reporting to the OAS General Assembly. Countries with resource constraints will have access to PAHO’s institutional capacity-building programmes, including curriculum development and teacher training in health promotion.
What this means
Frequently asked questions
What are the minimum physical activity requirements in the new guidelines?
The PAHO/OAS guidelines recommend at least 150 minutes of moderate-intensity physical activity per week for all school-age children, aligned with WHO guidance on child and adolescent physical activity. This can include curricular physical education, recess, and integrated movement during other lessons.
Which foods are restricted under the nutrition standards?
The guidelines restrict or eliminate ultra-processed foods, sugar-sweetened beverages, foods high in sodium, and products with excessive added sugars and unhealthy fats from school cafeterias and vending machines. PAHO has published specific nutrient thresholds and food classification systems to support member states in implementation.
How will countries monitor compliance with these guidelines?
PAHO will provide standardized monitoring tools and indicators, including school audits, student dietary and activity surveys, and anthropometric measurements. Data will be aggregated at the national and regional levels for reporting to the OAS and the broader international community.
As obesity-related chronic diseases continue to drive healthcare costs and mortality across the Americas, school-based interventions represent a critical investment in population health. The PAHO/OAS guidelines offer member states an actionable framework grounded in evidence, with institutional support for sustained implementation. Success will depend on coordinated action across health, education, and food policy sectors, alongside adequate resource allocation and political commitment from national governments.
