To define the prevalence of and the degree to which exercise barriers decrease odds of exercise participation among persons with SCI reporting annual household income greater than $50,000.
In this cross-sectional study, 180 individuals completed a Web survey of personal characteristics and exercise barriers. Over half (n=89) reported annual household incomes greater than $50,000. Chi-square and Mann-Whitney U identified personal characteristic differences between exercisers and nonexercisers. Odds ratios (OR) determined barriers that decreased odds of exercise participation. Significance was set at α < 0.05.
Eighty-seven percent of respondents were currently exercising (n=61). No differences discriminated exercisers and nonexercisers by gender, age, race, age at injury, injury level or completeness, education level, and total comorbidities or medications. A higher percentage of exercisers were full-time employed or married. Nonexercisers reported more barriers (4.9 ± 2.4 vs 2.21 ± 1.8). Only one barrier was highly prevalent and impactful (lack of motivation). The most impactful barrier, "too lazy to exercise," was the 9th most prevalent barrier (14%). Persons reporting this as a barrier were 19 times less likely to be exercising.
Among high-income households, highly prevalent barriers may not decrease odds of exercise participation. Knowledge and psychological barriers had the greatest impact on odds of exercise participation.
确定家庭年收入超过50,000美元的脊髓损伤患者中运动障碍的患病率以及运动障碍降低运动参与几率的程度。
在这项横断面研究中，180名个体完成了一项关于个人特征和运动障碍的网络调查。超过一半（n = 89）的人报告家庭年收入超过50,000美元。卡方检验和曼-惠特尼U检验确定了运动者和非运动者之间的个人特征差异。比值比（OR）确定了降低运动参与几率的障碍。显著性水平设定为α < 0.05。
87%的受访者目前正在运动（n = 61）。在性别、年龄、种族、受伤年龄、损伤水平或完整性、教育水平以及合并症或药物总数方面，运动者和非运动者之间没有差异。较高比例的运动者为全职工作或已婚。非运动者报告的障碍更多（4.9 ± 2.4对2.21 ± 1.8）。只有一个障碍非常普遍且有影响（缺乏动力）。最有影响的障碍“懒得运动”是第九大普遍存在的障碍（14%）。将此作为障碍报告的人运动的可能性低19倍。
在高收入家庭中，普遍存在的障碍可能不会降低运动参与几率。知识和心理障碍对运动参与几率影响最大。
