Research Interests

Dr. Newton's research interests center on addressing health disparities in African American children, adults, and older adults.  Although much of his work involves developing physical activity promotion interventions, he also engages in weight loss studies.

Dr. Newton utilizes community-based and technology-based interventions to address health disparities. Currently, Dr. Newton leads studies assessing the effect of a community-based physical activity intervention in older African American adults and a mobile phone based intervention targeting increased physical activity in young children. Dr. Newton is also involved in two primary care weight management programs and several childhood physical activity and/or weight management studies.
