Predictors of leisure time physical activity among people with spinal cord injury

Ann Behav Med. 2012 Aug;44(1):104-18. doi: 10.1007/s12160-012-9370-9.


Background: Most studies of physical activity predictors in people with disability have lacked a guiding theoretical framework. Identifying theory-based predictors is important for developing activity-enhancing strategies.

Purpose: To use the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework to identify predictors of leisure time physical activity among people with spinal cord injury (SCI).

Methods: Six hundred ninety-five persons with SCI (M age=47; 76% male) completed measures of Body Functions and Structures, Activities and Participation, Personal Factors, and Environmental Factors at baseline and 6-months. Activity was measured at 6 and 18 months. Logistic and linear regression models were computed to prospectively examine predictors of activity status and activity minutes per day.

Results: Models explained 19%-25% of variance in leisure time physical activity. Activities and Participation and Personal Factors were the strongest, most consistent predictors.

Conclusions: The ICF framework shows promise for identifying and conceptualizing predictors of leisure time physical activity in persons with disability.
