A Study of Hypertension and Fitness of Individuals with Spinal Cord Injury: A Cross-Sectional Study

<b>Background/Objectives:</b> Individuals with spinal cord injuries have a higher incidence of chronic conditions such as hypertension and cardiovascular diseases due to a sedentary lifestyle and low levels of physical activity caused by their disability. Additionally, their physical fitness levels are lower compared to those without disabilities. This cross-sectional study aimed to investigate the relationship between hypertension and the fitness of individuals with spinal cord injuries in South Korea while considering differences across sexes and spinal cord injury levels. <b>Methods:</b> This study used data for 835 individuals with spinal cord injuries aged 20-64 years who visited the Korea Paralympic Committee fitness standard test centers from 2018 to 2022, obtained from the Korea Culture Information Sports Association's big data market. The data were analyzed using a series of <i>t</i>-tests, a one-way analysis of variance, a logistic regression analysis, and the four-quartile method. <b>Results:</b> The prevalence of hypertension was 24.4%, and it was different according to the spinal cord injury impairment level. A lower grip strength, a lower arm curl, and a higher body mass index were associated with increased blood pressure. <b>Conclusions:</b> Therefore, a high level of physical strength in people with spinal cord injuries is thought to contribute to lowering blood pressure.
