How does accumulated stress, or allostatic load, affect a community’s ability to respond to shocks or crises?
Public health practitioners have long understood the impact of allostatic load—accumulated stress at the individual level. When a person experiences long-term or repeated stress, the body can remain in a heightened state to the point where an individual’s health can begin to decline.
In the public health sector, this concept has been the focus of a growing body of research on how chronic stress and trauma—such as witnessing violence or experiencing discrimination or abuse—affect individual health across the lifespan.
Building on key findings in this area, the Robert Wood Johnson Foundation (RWJF) engaged RAND to investigate a slightly different question: whether a community that experiences challenges—for instance, high unemployment, community violence, segregation, or high opioid use—could develop community allostatic load, which, in turn, could affect how it responds to future traumatic events.
The research team developed a framework for community allostatic load, and explored whether it could explain why two similar communities might respond to the same traumatic event in different ways.
Chronic stress related to issues such as inequality can complicate an individual’s ability to respond to acute shocks, and influence how a community responds collectively.
Communities can be strengthened by taking steps to alleviate stress factors, such as developing a coordinated response plan for stress-inducing events and effective communication and public education campaigns.
Community leaders can use measures to describe the current stress level in a community and sense challenges before a triggering event occurs.
In creating this framework, the ultimate goal of this research is to provide public health practitioners and other leaders with new ways of thinking about community stressors—which in turn may lead to new approaches for decreasing stress and promoting community health and well-being.
Support for this research was provided by a grant from the Robert Wood Johnson Foundation.

Help Communities Prepare for, Withstand, and Recover From Disaster
RWJF wants to learn how communities change norms, tackle inequities, and become more resilient. Community-partnered research is needed to understand how change happens so communities can turn the science of resilience into widely adopted practice.
