Our Work

Chronic diseases such as heart disease, cancer, diabetes and asthma are leading causes of death and disability in the U.S. They are also a growing health problem in lowincome countries around the world. These diseases disproportionately affect communities of color and low-income populations, and are responsible for close to 75 percent of all U.S. health care costs.

Successful prevention strategies begin with recognizing the complex interplay of social factors that drive chronic disease, including poverty, racism, education, access to care and local community environments.

At PHI, we oversee a diverse portfolio of cutting-edge chronic disease prevention programs that collectively work to address these social determinants of health, with an emphasis on policy and systems change to have the broadest impact.

Building Health Equity

Policy change can quickly impact large-scale inequities. In California, PHI co-sponsored a state-wide initiative that doubled the value of SNAP benefits (food stamps) when recipients purchase California-grown fruits and vegetables.
