PRIORITY #2

Support and promote evidence-based pediatric and adult obesity prevention programs and services.

Obesity prevention, both primary and secondary, must begin early and continue throughout life. Comprehensive behavioral programs that combine nutrition counseling, physical activity, and behavior modification are effective in preventing obesity and improving cardiometabolic health in adults and children.¹²³ Early-life interventions, including prenatal and postpartum care, family-centered education, and school-based programs, reduce obesity risk later in life.⁴⁵⁶ Community and policy-level strategies, such as improving built environments, reducing food deserts and insecurity, and implementing fiscal measures like sugar-sweetened beverage taxes, reduce obesity prevalence and promote population health.⁹¹⁰ For older adults, prevention should balance adiposity reduction with maintenance of lean mass through resistance training and adequate protein intake.¹¹¹² Equity-driven prevention ensures that programs reach high-risk and underserved populations through culturally tailored interventions embedded in schools, workplaces, and community health systems.¹³¹⁴ 

  1. Preventing or slowing the natural progression of the disease of obesity, starting with overweight, across the lifespan requires sustained, evidence-based interventions that integrate clinical, community, and policy actions to promote behaviors supporting health, prevent excess adiposity, and reduce adipose related-disease risk.
  2. Social, environmental, and commercial determinants of health, including but not limited to access to healthy food, safe places for physical activity, stable housing, transportation, and supportive community resources, play a major role in the risk of overweight and obesity alongside biological and genetic factors. Emerging evidence also suggests that environmental exposures, such as endocrine-disrupting chemicals and pollutants, may further influence metabolic health, highlighting the need for broader prevention strategies that address both built and environmental risks.
  3. Strengthening social support systems and improving the environments where people live, work, learn, and play are essential components of obesity prevention. Policies that reduce food insecurity, improve nutrition security, enhance the built environment, and expand access to healthcare and community resources are foundational to improving health, particularly for individuals with limited financial resources.

  • Scale access to comprehensive behavioral prevention programs in healthcare, community, and workplace settings.
  • Integrate evidence-based early-life and family-focused interventions across pregnancy, infancy, and childhood.
  • Strengthen social supports that influence health, including programs that improve food and nutrition security, access to healthcare, housing stability, and community resources.
  • Improve the built environment to support physical activity through safe walkable communities, active transportation, parks, and recreation infrastructure.
  • Implement policies that increase access to healthy foods and reduce food insecurity, including community nutrition programs and healthy food retail initiatives.
  • Strengthen digital, remote, and workplace-based prevention options to expand reach and engagement.
  • Implement environmental and fiscal policies (e.g., active transport, healthy food access, sugar-sweetened beverage taxes) that make health-promoting choices easier.
  • Support prevention programs for older adults that maintain muscle and function alongside healthy weight.
  • Ensure equitable funding and culturally relevant delivery of prevention initiatives to reach at-risk communities.
  • Promote research on obesity prevention to enhance our understanding of what programs and policies optimize health and how they can be implemented.
