Cancer prevention among adults aged 45-64 years: setting the stage.

As part of setting the stage for this supplement to the American Journal of Preventive Medicine, a life-course perspective is presented to assist in understanding the importance of cancer prevention for adults in midlife, a period roughly spanning 20 years between ages 45 and 64 years. Drawing on disciplinary perspectives from the social sciences and public health, several life-course themes are delineated in this article: how specific life transitions present unique opportunities for interventions to inform policy and practice that can improve population health outcomes; how interventions can be focused on those at particular life stages or on the entire life course; and how the onset and progression of chronic conditions such as cancer are dependent on a complex interplay of critical and sensitive periods, and trajectory and accumulation processes. A translational research framework is applied to help promote the movement of applied public health interventions for cancer prevention into practice.

Designing iCanFit: A Mobile-Enabled Web Application to Promote Physical Activity for Older Cancer Survivors.

Background: Most older cancer survivors (OCS) do not engage in regular physical activity (PA) despite well-known health benefits. With the increased use of mobile technologies among older adults, mobile tools may be an effective method to deliver PA promotion programs for OCS.

Objective: To document the process of designing an OCS-friendly mobile-enabled Web application of PA promotion program.
