Populations in isolated Indian Health Service regions and Appalachian counties have disproportionately worse maternal and child health (MCH) outcomes than national averages. Public health professionals serving these populations have identified the need for training in MCH epidemiology. To increase the capacity in MCH epidemiology of health workers serving in rural, isolated, and underserved Indian Health Service regions and Appalachian counties, this project will develop and implement a 15-credit online Graduate Certificate in MCH Epidemiology, using innovative internet technologies and delivery approaches that surpass the face-to-face classroom experience.
