Study Design: Secondary analysis of cross-sectional data.
Objectives: To estimate the amount of very low-intensity activity (VLPA) or inactive daily awake time that people with spinal cord injury (SCI) engage in and to determine correlates of VLPA/inactivity in this population.
Setting: Community (Ontario, Canada).
Methods: Participants with SCI (n = 695; M-age = 47 years; Myears post-injury = 15 years, 76% men) completed telephone interviews. Demographic details and injury-related characteristics were self-reported. Total daily physical activity (for example, mild, moderate and heavy intensity) was measured using the Physical Activity Recall Assessment for People with SCI (PARA-SCI). VLPA/inactivity was calculated by subtracting total daily physical activity time from daily awake time. Correlates of VLPA/inactivity were assessed using a hierarchical linear regression where demographic variables were entered on the first step and injury-related characteristics were entered second.
Results: Participants reported VLPA/inactivity for approximately 768 +/- 169 min per day, or 84%, of their awake time. The regression model predicting VLPA/ inactivity was not significant.
Conclusion: People with SCI spend the majority of their awake time in VLPA/ inactivity. However, VLPA/ inactivity did not differ as a function of demographic or injury-related variables, suggesting that all segments of the SCI population could benefit from strategies to reduce inactivity.
