Abstract Background:<\b>
Emerging evidence suggests that the combination of sedentary behavior and physical activity (PA) may be important for physical health and quality of life in cancer survivors. As such, it is important to investigate behavioral profiles of daily activity in cancer survivors. In this study we identified distinct profiles based on physical activity and sedentary time, and examined whether these profiles differ by age or sex. Method: Accelerometer data from seven international studies (n=1150 participants) were pooled. Latent profile analysis was conducted to identify behavioral profiles, based on total sedentary time, sedentary time accumulated in bouts of 20+minutes, total time in light PA (LPA), the 75th-percentile of total counts/minute in LPA, total time in moderate-to-vigorous PA (MVPA) and MVPA time accumulated in bouts of 10+minutes. Results:<\b>
Preliminary analyses (n=564 participants, mean age: 62yrs, 77% female) identified five behavioral profiles. Profile 1 was characterized as ‘very active’ with the highest MVPA and low sedentary time (mean age: 62yrs, 77% female), Profile 2 as ‘active’ with the lowest sedentary time and high MVPA and 75th LPA percentile (age: 58yrs, 85% female), Profile 3 as ‘average’ with average sedentary time, LPA and MVPA (age: 62yrs, 89% female), Profile 4 as ‘sedentary and inactive’ with the highest sedentary time and lowest MVPA (age: 66yrs, 56% female) and Profile 5 as ‘sedentary’ with lower sedentary time and higher MVPA compared to Profile 4 (age: 63yrs, 70% female). Conclusion:<\b>
The behavioral profiles identified can be used to tailor interventions to improve health behaviors in cancer survivors.
