Background: Adverse health effects of sedentary behaviour on cancer risk and health outcomes in cancer survivors have been reported but few studies have examined quality of life (QoL) and no study has focused on kidney cancer survivors (KCS). The purpose of this study was to estimate the prevalence of sitting time among KCS and to determine any associations with QoL.
Methods: All 1985 KCS diagnosed between 1996 and 2010 identified through a Canadian provincial Registry were mailed a survey that consisted of the modified domain-specific sitting time questionnaire, the Godin Leisure Time Exercise Questionnaire and several Functional Assessment of Cancer Therapy (FACT) QoL scales. Standard demographic and medical variables were also reported.
Results: Completed surveys were received from 540 KCS. The mean hours of sitting time were 8.0 +/- 4.7 for a work-day and 6.5 +/- 3.8 for a non-work day. After adjustment for key covariates, analyses of covariance indicated that the only significant relationship was an unexpected positive association between sitting time on a work day and emotional well-being (p = 0.019). Moreover, the only variable to moderate these associations was age, with younger KCS under age 60 showing the expected negative associations between sitting time and physical and functional aspects of QoL.
Conclusion: KCS sit for a significant amount of time on work days and non-work days, however, there were few associations with QoL. Future observational studies and randomized controlled trials are warranted to examine sitting time and health outcomes among KCS.
