Abstract

BACKGROUND: Although persons with multiple sclerosis (MS) are encouraged to engage in physical activity, they are less active than the general population and experience poorer emotional/cognitive health, underscoring the need for increased understanding of the factors independently associated with exercise in MS. METHODS: Six hundred forty people with MS completed a detailed demographic survey, the Godin Leisure-Time Exercise Questionnaire, and Quality of Life in Neurological Disorders short forms. The average number of weekly sessions of exercise was examined as a count, as a binary variable (a weekly minimum of 4 sessions of physical activity), and as an ordinal variable of being active using multivariable zero-inflated negative binomial, logistic, and ordered logistic regression models, respectively. Primary predictors of interest included depression, cognitive function, positive affect, and lower extremity functioning as measured by the Quality of Life in Neurological Disorders short forms. RESULTS: The study sample was 91% White race, 83% female, 65% with a relapsing-remitting MS diagnosis. The mean participant age was 52 years. Across analyses, body mass index and disability were inversely associated with exercising. Greater lower extremity impairment was associated with decreased odds of exercising and being active. A greater burden of depression symptoms was correlated with lower odds of engaging in physical activity. People with MS with higher self-reported cognitive functioning were less likely to engage in any exercise, but it was not associated with frequency of activities. CONCLUSIONS: These results demonstrate associations between exercise and cognitive and emotional health in people with MS, underscoring the need to consider these factors when designing MS-targeted physical activity recommendations
