title: A description and estimate of very low-intensity activity and inactive awake time in community-dwelling adults with chronic spinal cord injury.
abstract: METHODS
  Secondary analysis of cross-sectional data.
  
  
  OBJECTIVE
  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.
  
  
  METHODS
  Community (Ontario, Canada).
  
  
  METHODS
  Participants with SCI (n=695; Mage=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.
  
  
  CONCLUSIONS
  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.
