Impacts of Comprehensive Services in Early Childhood Education
Early childhood development and education are key determinants of future health and well-being. Early Childhood Development and Education – Healthy People 2030 | odphp.health.gov

Social Determinants of Health: Center-Based Early Childhood Education
High-quality early childhood education prepares children for school and improves physical health, mental health, developmental outcomes, and lifelong well-being, especially for children facing social or economic disadvantages.
Children in high-quality programs learn social-emotional skills which help reduce behavioral challenges and support positive mental health throughout childhood and adolescence.
Early childhood development and educational opportunities are affected by various environmental and social factors, including early life stress, socioeconomic status, relationships with parents and caregivers, and access to early education programs. The Foundations of Lifelong Health
Social Determinants of Health
Social determinants of health (SDOH) are the conditions in the environments where people are born, live, learn, work, and play, which affect a wide range of health and quality-of-life outcomes and risks.
