An Integrated Socio-Environmental Model of Health and Well-Being: a Conceptual Framework Exploring the Joint Contribution of Environmental and Social Exposures to Health and Disease Over the Life Span

Purpose of the review Environmental and social determinants of health often co-occur, particularly among socially disadvantaged populations, yet because they are usually studied separately, their joint effects on health are likely underestimated. Building on converging bodies of literature, we delineate a conceptual framework to address these issues.

Recent findings Previous models provided a foundation for study in this area, and generated research pointing to additional important issues. These include a stronger focus on biobehavioral pathways, both positive and adverse health outcomes, and intergenerational effects. To accommodate the expanded set of issues, we put forward the Integrated Socio-Environmental Model of Health and Well-Being (ISEM), which examines how social and environmental factors combine and potentially interact, via multi-factorial pathways, to affect health and well-being over the life span. We then provide applied examples including the study of how food environments affect dietary behavior.

Summary The ISEM provides a comprehensive, theoretically informed framework to guide future research on the joint contribution of social and environmental factors to health and well-being across the life span.

A life-course approach to health: synergy with sustainable development goals | Bulletin of the World Health Organization

The aim of this article is to show how a life-course approach can be extended to all health topics, age groups and countries by building on a synthesis of existing scientific evidence, experience in different countries and advances in health strategies and programmes. Aligned with the Sustainable Developmental Goals and Universal Health Coverage, a life-course approach can facilitate the integration of individual, social, economic and environmental considerations.

BUILDING HEALTH THROUGHOUT THE LIFE COURSE | PAHO

Health is a component of and a key resource for human development. It results from a cumulative process of continuous interaction between exposures and experiences, which have an impact at both the individual and population levels, not only episodically but over time, and with trans-generational effects (1). The increase in human life expectancy by approximately 30 years over the last century provides a compelling reason to expand health-related goals beyond simple survival (2, 3).

In the Region of the Americas, the effort to increase life expectancy has been successful; however, the increase in healthy life expectancy has not kept pace. On average, 8 of every 10 people who are born in the Region will live beyond age 60, and more than 4 in 10 will live past 80 (4). One-quarter of those who live past 80 will live with poor health (4). According to estimates, people in the Region live on average 9 years with functional limitations or disability (5). An increased lifespan, but with longer periods of illness and dependence on care provided by others, is a great burden for States, societies, and families, and a significant challenge for public health.
