Allostasis, health, and development in Latin America

Area of Science:

• Public Health
• Lifespan Development
• Environmental Health

Background:

• Adverse childhood experiences (ACEs) are linked to lifelong health disparities.
• Latin America and the Caribbean face significant social and health inequalities, exacerbating ACEs' impact.
• Environmental and social stressors (pollution, violence, malnutrition) critically affect health outcomes.

Purpose of the Study:

• To propose an allostatic framework detailing the impact of childhood experiences on lifespan health.
• To focus on the specific context of Latin American and Caribbean countries.
• To inform regional interventions and public policy recommendations.

Main Methods:

• Review of manifestations of ACEs across psychological, brain, and physiological levels.
• Presentation of an allostatic framework on the cumulative burden of environmental stressors.
• Exploration of the framework's relevance for policy and intervention development.

Main Results:

• Childhood experiences and environmental stressors lead to psychological, brain, and physiological dysfunctions.
• The allostatic framework illustrates cumulative stress impacts on cardiovascular, metabolic, immune, and neuroendocrine systems.
• This approach highlights the need for personalized care and evidence-based policy.

Conclusions:

• An allostatic framework effectively integrates environmental and health factors across the lifespan.
• This framework is crucial for developing targeted interventions and child-centered policies in vulnerable regions.
• Further research is needed to profile social/environmental conditions for personalized health strategies.
