Background: Our data have indicated that minority breast cancer survivors are receptive to participating in lifestyle interventions delivered via email or the Web, yet few web-based studies exist in the population.

Objective: To address these limitations, we examined the feasibility and preliminary results of A Lifestyle Intervention via Email (ALIVE) in a sample of racial and ethnic minority cancer survivors.

Methods: Survivors (Mean age= 52, 83% African American) were recruited and randomized to either a 3-month physical activity or a dietary condition.

Similarly, reductions in total sedentary time among the physical activity (-304 vs.-59
