Leisure time physical activity in middle-aged and older adults aging with long-term spinal cord injury: Changes over six years

Abstract

BackgroundRegular leisure time physical activity (LTPA) has beneficial health effects in people with spinal cord injury (SCI). Yet, participation in LTPA is low, and little is known about changes many years after injury. ObjectivesTo determine changes in LTPA in middle-aged and older adults with long-term SCI over six years, investigate associations with gender, age, injury characteristics and changes in secondary health conditions and activity limitations, and investigate factors related to being physically active or sedentary. MethodsPart of the Swedish Aging with Spinal Cord Injury Study (SASCIS). LTPA was assessed twice over a six-year period with the Physical Activity Recall Assessment for people with Spinal Cord Injury (n = 75; 32% women, mean age 67 years, mean time since injury 31 years, injury levels C1-L3, AIS A-D). Changes were assessed with paired t-tests, McNemar test and Wilcoxon signed-rank test, associations with multivariable regression and group comparisons with Mann-Whitney U test and Chi Square test. ResultsOn group level participation in LTPA did not change, but the variability was substantial on individual level. There were no significant associations between changes in LTPA and the investigated variables. Among sedentary participants, higher level and severity of injury were overrepresented and the activity limitations were greater. ConclusionOur findings indicate stability in LTPA over time, but with a large individual variation. In many participants LTPA was insufficient to reach positive health effects. Promoting participation in LTPA is therefore an important part of the long-term management of middle-aged and older adults aging with long-term SCI.
