Weekly physical activity trajectories differ between adolescent and adult childhood cancer survivors and controls, with weekend drops in activity common across groups.

The study identified four weekly physical activity trajectories among adolescent and adult childhood cancer survivors using accelerometer data. Key factors associated with different trajectories included sex, age, sleep, and parental education, with diagnosis important only in adolescents. Adolescent survivors had fewer individuals in the low activity trajectory compared to controls, while adult survivors showed no low regular MVPA trajectory.

Participants: N/A
Duration: 1 week
Intervention: Observational study of weekly physical activity patterns (no intervention)
Outcome: Weekly trajectories of moderate-to-vigorous physical activity (MVPA) and light physical activity (LPA) measured by accelerometer
Effect Size: N/A
Population: Adolescent (9-18 years) and adult (18-49 years) childhood cancer survivors from PACCS and SURfit studies, plus controls

Result: The study identified four weekly physical activity trajectories among adolescent and adult childhood cancer survivors using accelerometer data. Key factors associated with different trajectories included sex, age, sleep, and parental education, with diagnosis important only in adolescents. Adolescent survivors had fewer individuals in the low activity trajectory compared to controls, while adult survivors showed no low regular MVPA trajectory.

Limitations

  • ⚠Observational design cannot establish causality

  • ⚠Adult survivors compared to different control group (Norwegian National Physical Activity Survey 2)

Frequently Asked Questions

What are the four physical activity trajectories identified in adolescent survivors?▼

Low regular; Medium, drop weekend; Medium, peak Friday; and Medium regular.

How did childhood cancer survivors compare to controls in terms of physical activity trajectories?▼

Adolescent survivors had fewer individuals in the low activity trajectory compared to controls, and adult survivors showed no low regular MVPA trajectory, suggesting more favorable allocation in survivors.

What factors were associated with different physical activity trajectories?▼

Sex, age at assessment, sleep, and parental education were key factors; diagnosis was important only in adolescent survivors.

What intervention is suggested by the study findings?▼

Targeted physical activity interventions for adolescent female survivors of CNS tumors, and interventions to prevent weekend drops in activity.
