['Emerging evidence suggests that light physical activity (LPA), besides moderate-to-vigorous physical activity (MVPA), may beneficially influence physical functioning of colorectal cancer survivors, but its relation with other health-related outcomes is unknown. We applied a biopsychosocial approach to investigate independent associations between self-reported LPA, MVPA, and multiple health-related quality of life (HRQoL) outcomes in 2- to 10-yr postdiagnosis colorectal cancer survivors.', 'Stage I-III colorectal cancer survivors diagnosed between 2002 and 2010 at Maastricht University Medical Center+, the Netherlands, were included in a cross-sectional study (n = 151). Time spent in LPA and MVPA (h·wk⁻¹), and HRQoL outcome scores (0-100 points) were assessed by validated questionnaires.', 'Median time spent in LPA and MVPA was 10.0 (interquartile range, 2.0-22.0) and 8.7 h·wk⁻¹ (4.5-15.0), respectively. In multivariable linear regression models, both LPA and MVPA were significantly and independently associated with higher physical functioning (mean difference [MD] between highest and lowest quartile, 10.2; 95% confidence interval [CI], 0.2-20.3; and 14.5; 5.1-23.9, respectively; both P-trend < 0.05). In addition, LPA was significantly associated with higher role functioning (MD, 19.5; 95% CI, 6.9-32.1; P-trend < 0.01) and lower disability (MD, -9.9; 95% CI, -17.8 to -1.9; P-trend = 0.02), independent from MVPA. Subgroup analyses showed that beneficial associations between LPA and HRQoL were mainly observed in women and participants with multiple comorbidities.'] Does light Physical Activity be Associated with Quality of Life after Colorectal Cancer?
