dc.descriptionThe Society of Behavioral Medicine (SBM) Annual Meeting is the most relevant and pertinent conference in the field of Health Behavior and Behavioral Medicine. This year I was awarded an oral presentation, which is only the second time I have received an oral presentation at SBM. This conference brings together a very impressive cohort of researchers that provides a great opportunity for networking and the sharing of ideas. My presentation took place on Thursday, March 27th at 3:30pm. The paper session was titled “Physical Activity and Cancer: Survivors on the Move” and was moderated by Dr. Kerry Courneya from the University of Alberta. My presentation was very well received by the audience of approximately 60 delegates. I received 3 questions immediately post presentation. One question related to the rationale for using the quality of life scale that I used. The second question (from Dr. Shannon Mihalko, Wake Forest University) related to the theoretical variables that may have mediated the effects of the intervention on physical activity behavior. This question was timely as we have a paper that is coming out next month in the Annals of Behavioral Medicine (refereed publication of SBM) that provides these details. The third question was from Dr. Frank Perna of the National Cancer Institute inquired about whether we controlled for the baseline effects of physical activity behavior. After the presentation session, I had a chance to speak with several individuals who were interested in my work. Most notably, I had the chance to meet and speak with Dr. Anna Hawkes. Dr. Hawkes is the Manager of the Psycho-Oncology Research Unit with The Cancer Council of Queensland (Australia). A few groups of researchers in Queensland are conducting similar work that I am in terms of exploring ways of facilitating physical activity in cancer survivors. Dr. Hawkes was very interested in the intervention tools we used so I was able to direct her to my website where I have made the intervention material (Exercise for Health: An Exercise Guidebook for Breast Cancer Survivors) available to the public. Perhaps of greater implications, Dr. Hawkes and I will be keeping in touch and exploring some potential collaborative opportunities between the Australian group, and our team here in Alberta (myself, Dr. Kerry Courneya). Dr. Hawkes will be sending me the intervention tools they have developed in Australia. This will be extremely helpful for me as I am currently revising the guidebook we developed for implementation into a future study that we have currently submitted for funding to CIHR. Aside from my presentation, SBM offered me the chance to catch up with other collaborators which I am currently working with. In particular, I was able to meet with Dr. Kristina Karvinen from East Carolina University. Dr. Karvinen and I are conducting a study exploring breast cancer patients’ attitudes and beliefs about exercising during the chemotherapy time period. I’m extremely appreciative of the funding received from the A & PDF Award Program.en
dc.description.abstractPurpose: The purpose of this study was to examine the longer term effects of pedometers and print materials on changes in physical activity (PA) and health-related quality of life (HRQoL) in breast cancer survivors that participated in a three month behavior change intervention. Methods: Breast cancer survivors (N=377) were randomly assigned to receive either: (a) a standard public health recommendation for PA (SR), (b) previously developed breast cancer-specific PA print materials (PM), (c) a step pedometer (PED), or (d) a combination of the two (COM). The primary endpoint was self-reported moderate/vigorous PA minutes per week (min•wk) at six months follow-up after the initial three month-intervention period. Results: 71% (266/377) of participants completed the six-month follow-up assessment. Based on intention-to-treat linear mixed model analyses, self-reported moderate-to-vigorous PA increased by 9 min•wk in the SR group compared to 39 min•wk in the PM group (Mean difference=30 min•wk; 95% CI=-44 to 104; p=.425), 69 min•wk in the PED group (M difference=60 min•wk; 95% CI=-13 to 132; p=.107), and 56 min•wk in the COM group (M difference=47 min•wk; 95% CI=-26 to 119; p=.210). The same pattern was observed for self-reported brisk walking. No differences were found for HRQoL or fatigue. Conclusion(s): Breast-cancer specific print materials and pedometers did not maintain significantly higher PA or HRQoL at six months follow-up in breast cancer survivors but the magnitude of the effect on PA (30-60 min•wk) was consistent with the immediate postintervention effect observed at the three-month postintervention timepoint. Issues of power resulting from additional loss-to-follow-up may account for the failure to achieve statistical significance. Additional research with larger sample sizes and more complete follow-up is warranted.en
