Abstract
PURPOSE: The purpose of this study was to examine and compare pre- to post-diagnosis change patterns of physical activity (PA) among breast, prostate, and colorectal cancer patients. Moreover, the study aimed to investigate sociodemographic and medical determinants of post-diagnosis PA and to identify patient subgroups at increased risk of inactivity. METHODS: A total of 912 cancer patients (457 breast, 241 prostate, 214 colorectal cancer) completed a questionnaire assessing their pre- and post-diagnosis PA behavior, and sociodemographic and medical variables. Age-adjusted regression and classification tree analyses were used to investigate PA determinants and detect subgroups that were most likely to meet or not meet PA guidelines. RESULTS: Across cancer types, we found that PA yet decreased from pre- to post-diagnosis, but that 54.1% of participants still reported to be meeting PA guidelines after the diagnosis. While post-diagnosis PA was strongly affected by previous PA behavior among individuals of all patient groups, other sociodemographic and medical determinants played different roles depending on cancer type. The results yielded that previously active, longer diagnosed patients with higher education levels were most likely to be meeting PA guidelines post-diagnosis, whereas specifically previously inactive prostate cancer patients had an increased likelihood of insufficient activity. CONCLUSIONS: An encouragingly high number of cancer patients indicated sufficient PA levels. For those having difficulties to maintain or adopt PA post-diagnosis, interventions should be tailored to the specific characteristics of each cancer type, as different factors are associated with PA for each patient group.
