The Application of the 24-Hour Movement Paradigm in People Diagnosed With Cancer: A Scoping Review.

Background: The 24-hour movement (physical activity-sedentary behavior-sleep) paradigm can promote an ability-focused approach to changing movement behaviors in people diagnosed with cancer. This scoping review aimed to explore how the 24-hour movement paradigm has been applied in people diagnosed with cancer, examining behavior measurement methods and associations between 24-hour movement behaviors and health variables.

Methods: A systematic search was conducted on the August 8, 2024. MEDLINE, Embase, and Cumulative Index of Nursing and Allied Health were searched. There were 5 steps: identifying the research question; identifying studies; study selection; charting the data; collating, summarizing, and reporting results. Study design, sample demographics, movement behavior measurement, analytical approach, and study outcomes were extracted. The review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews framework.

Results: Of 88 records identified, 7 studies met inclusion criteria. All studies were cross-sectional with movement behaviors as the exposures. One study was conducted in children. Four studies used device-based measures for all behaviors, 2 used device-based measures of daytime behaviors with self-reported sleep, and 1 study used self-report for all behaviors. All studies used isotemporal substitution modeling. One study applied a compositional data approach. Outcomes included anthropometrics, quality of life, cognitive function, and bone health. Reallocating time into moderate to vigorous physical activity was associated with the most consistent health benefits.

Conclusions: Limited studies have applied the 24-hour movement paradigm in this population. Most used devices for measurement. While current evidence is constrained by cross-sectional designs and limited generalizability, results support the positive impact of reallocating time from other behaviors into physical activity.
