Physical Activity Promotion in Cancer Follow-Up Care

This study aims at testing the efficacy of a physical activity (PA)intervention in an outpatient oncology setting. We plan to compare Brief Advice for PA (MD advice plus contact control) vs. Extended Advice (MD advice plus telephone-based PA counseling by research staff) over 3 months among 300 women who have completed treatment for breast cancer in the past 2 years. Specific Aims: The primary aim is to examine the effects of oncologists\' advice on PA plus telephone counseling (Extended Advice) vs. oncologists\' advice (Brief Advice) alone on minutes of moderate-intensity PA at 3 months among 300 sedentary women who have completed treatment for breast cancer. Secondary aims include examining a) the effects of the two interventions on participants\' moderate-intensity PA at 6 and 12 months, b) the effects of the interventions on participants\' physical functioning, fatigue, vigor and quality of life (QOL) at 3, 6 and 12 months, and c) the acceptability of the interventions to the oncologists and the usefulness of the interventions to patients.
