Summary
Opportunities for physical activity are unequally distributed. An Enhanced Socioecological Model shows how housing policies impact active living, promoting equitable, climate-resilient urban development for better public health.
Area of Science:
- Public Health
- Urban Planning
- Environmental Science
Background:
- Physical activity is crucial for population health but unequally accessible.
- Social determinants, climate change, and urbanization affect active living choices and necessity.
Purpose of the Study:
- To introduce an Enhanced Socioecological Model integrating planetary health and the necessity-choice continuum.
- To provide a tool for assessing large-scale, non-health sector interventions.
Main Methods:
- Synthesized the Ecological Model of Active Living, Social Determinants of Health, and Planetary Health frameworks.
- Applied the enhanced model to Brazil's Minha Casa, Minha Vida and the US Choice Neighborhoods Initiative.
Main Results:
- Peripheral housing developments (Minha Casa, Minha Vida) increased necessity-driven mobility and vulnerabilities.
- In situ redevelopment (Choice Neighborhoods Initiative) promoted choice-driven activity through improved amenities and connectivity.
Conclusions:
- The Enhanced Socioecological Model unifies research and policy for equitable, climate-resilient urban development.
- This framework promotes public health by addressing the social and environmental determinants of physical activity.

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.

Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities.

Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
