Behavior, Environment & Health

The leading causes of illness and death among general population are largely preventable. Health outcomes are grounded in their social environments and are frequently mediated by their behaviors. Behaviors are influenced at the individual, peer, family, school, community, and societal levels. As illustrated by the following achievements of research findings, health outcomes are linked to multiple environmental factors.

We have explored the impacts of inequitable access to health food and exercise on obesity.
