UCD leads $3M community-based project Support Local Journalism Leigh Ann Simmons, a professor and chair in the Department of Human Ecology and co-director of the Perinatal Origins of Disparities Center, has received a $3 million award to build and strengthen community-based health and social supports systems in Yolo County to address adverse childhood experiences (ACEs) and toxic stress. ACEs can include experiences such as witnessing violence in the home or community, abuse or neglect. Research has shown that ACEs and toxic stress in childhood can have lifelong negative consequences on health and well-being. Some of the health consequences include higher rates of chronic disease, shorter life span, homelessness, unemployment and behavioral health problems.
