Exercise participation barrier prevalence and association with exercise participation status in individuals with spinal cord injury.

STUDY
DESIGN: Pass-code protected web survey.
OBJECTIVES: Defining exercise participation barrier prevalence and association with exercise participation status in adults with spinal cord injury (SCI).
SETTING: World-wide web.
METHODS: Individuals ≥18 years with ShCI in the United States completed a pass-code protected website survey (N=180). Odds ratios (OR) and OR 95% confidence interval (95% CI) assessed association between barrier presence and exercise participation.
RESULTS: No differences existed between exercisers and non-exercisers with respect to age, gender, injury level, injury duration, education level, or employment status. A larger percentage of non-exercisers reported household annual incomes <$7,500. The five most prevalent barriers were not associated with participation status (all OR 95% CI included 1). Low prevalence (≤13%) characterized four of the five barriers most strongly related to being a non-exerciser. Identifying too lazy, too difficult, or no interest as a barrier decreased odds of being an exerciser by 86%, 83%, and 71%, respectively. Not liking exercise decreased the odds of being an exerciser by 90%.
CONCLUSION: Highly prevalent barriers were not associated with exercise participation status, whereas low prevalence barriers were strongly related to being a non-exerciser. Internal barriers had the strongest association with exercise participation status. The possible association between socioeconomic factors and exercise participation may be underappreciated. The most effective interventions to increase exercise participation may be multifocal approaches to enhance internal perceptions about and motivation to exercise, increase knowledge of how and where to exercise, while also reducing program and transportation financial costs.
