Recent systematic reviews and meta-analyses of cohort studies show that physical activity can reduce mortality and morbidity in diabetes and obesity-related cancers. Yet, there have been few efforts to promote physical activity within the context of female cancer survivorship, particularly among women with diabetes. In response, investigators proposed to refine and test the feasibility and acceptability of a 4-month multi-modal lifestyle intervention in African Americans (AA) with diabetes and who are breast or endometrial cancer survivors. This web-based, lifestyle intervention, coupled with coaching calls and in-person exercise sessions, may be an effective way to promote physical activity and healthy survivorship. The primary goal is for participants to participate in 30 minutes of moderate-to-vigorous physical activity five times a week. The investigators' aims : i) refine a theory-driven healthy lifestyle intervention, that is delivered via computer technologies and periodic in-person group exercise sessions with appropriate content, literacy demand and graphics, ii) assess the preliminary effects of the intervention on the primary outcome of level of moderate to vigorous physical activity (MVPA), as measured by accelerometry; weight A1C and evaluate the effect of eating behaviors, wellbeing/functioning (quality of life, depressive symptoms, self-efficacy), compliance/adherence to protocol and acceptability on response to the intervention.
