Background: Physical activity is an effective way to positively influence health outcomes among cancer survivors. Few studies have examined physical activity and sedentary behavior among lung cancer survivors. Further, these studies have used self-report measures of physical activity, which may bias results (e.g., overestimation) and lead to incorrect conclusions. Only one study to date has reported on objectively-assessed sedentary behavior among lung cancer survivors. The primary aim of this currently ongoing study is to determine the prevalence of objectively-assessed physical activity and sedentary time among lung cancer survivors. Method(s): Lung cancer survivors in Southern Alberta diagnosed between 1999 and 2014 are currently being recruited to participate. Eligibility criteria include: confirmed non-small cell lung cancer, completed treatment, and not living in hospice/palliative care. Consenting participants wear an Actigraph GT3X+ accelerometer on their hip for seven days. Time spent sedentary, in light and in moderate-to-vigorous intensity physical activity are derived from the accelerometer data and processed using 60-second epochs. Physical activity and sedentary behavior accumulated in 10 minute and 30 minute continuous bouts will be examined. Result(s): Recruitment began in June, 2016. A total of 660 survivors were invited and 113 have agreed to participate. Of the 374 survivors that did not respond, most indicated they were not interested (n=115). Others denied having lung cancer (n=6) or had invalid contact information (n=27). Six were deceased. Currently the response rate is 18.2%. Of the 113 that consented, eight participants withdrew due to health concerns (n=4), time constraints (n=2), and loss of interest in the study (n=2). Of the 105 participants, the median age at diagnosis was 66 years, and 72 years at recruitment, the majority were female (n=62), and 85 had a smoking history. Adenocarcinoma was the most common diagnosis (n=65). The majority of participants were diagnosed stage I (n=53) with others diagnosed at stage II (n=23), III (n=18), and IV (n=11). Overall, 65 survivors underwent a lung resection while 18 of those received adjuvant therapy. Other treatments included concurrent chemotherapy and radiation (n=11) and radical radiation alone (n=23). Conclusion(s): This study will be the first to report on objectively assessed physical activity and sedentary time among a population-based sample of lung cancer survivors. Despite inherent difficulties of this type of research (e.g., older population), the positive response rate suggests high participation interest. We expect to reach our recruitment target of 140 patients by September, 2016, with data analysis completed in November, 2016.
