Associations with being physically active and the achievement of WHO recommendations on physical activity in people with spinal cord injury.

STUDY DESIGN: Secondary data analysis from the cross-sectional survey of the Swiss Spinal Cord Injury Cohort Study. OBJECTIVES: To explore associations with physical activity (PA) levels in people with spinal cord injury (SCI) with the specific aim to identify aspects that potentially explain being physically active (PHYS-ACT) and the achievement of the World Health Organization recommendations on PA. SETTING: Community sample (n=485). METHODS: Participants who completely answered four items of the Physical Activity Scale for Individuals with Physical Disabilities were included. Two outcome measures were defined: (1) being PHYS-ACT vs being completely inactive and (2) achieving WHO recommendations on PA (ACH-WHO-REC) (at least 2.5 h per week of at least moderate intensity) vs performing less. Independent variables were selected from the original questionnaire by applying the ICF framework. Multivariate logistic regression analyses were conducted. RESULTS: In the participants (aged 52.8±14.8; 73.6% male) older age decreased, but being a manual wheelchair user increased the odds of achieving both outcomes. Social support and self-efficacy increased the odds of being PHYS-ACT. Use of an intermittent catheter increased, whereas dependency in self-care mobility and coping with emotions decreased the odds for ACH-WHO-REC. Experiencing hindrances due to accessibility is associated with increased odds for ACH-WHO-REC. CONCLUSION: Being PHYS-ACT at all and achieving the WHO recommendations on PA are associated with different aspects. Applying the ICF framework contributes to a comprehensive understanding of PA behavior in people with SCI, which can tailor the development of interventions. Longitudinal studies should be initiated to test these associations for causal relationships.
