Health-related physical fitness and blood pressure in people with intellectual disabilities in Korea

Abstract

Abstract Hypertension is one critical health issue causing cardiovascular diseases. There has been a common concern among health researchers that the prevalence of hypertension, known as high blood pressure, has been more frequently observed among people with intellectual disabilities, compared to the general population. Thus, this study aims to identify which health-related physical fitness and body composition factors are significantly related to both systolic and diastolic blood pressures among people with intellectual disabilities. The data from 2180 people with intellectual disability who conducted the physical fitness tests from 2019 to 2020 were used for this study. Four physical fitness tests (i.e., 3-min step, grip strength, sit-up, and sit and reach) and two body compositions (i.e., body mass index and body fat %) used as predictors, and two blood pressures (i.e., systolic blood pressure and diastolic blood pressure) were used as outcome variables. A regression analysis was performed to examine the proposed associations. The regression test revealed that 3-min step, body mass index, and body fat % were significantly associated with both systolic blood pressure and diastolic body pressure. This research contributes to our understanding of the roles of body compositions and aerobic endurance in preventing hypertension among people with intellectual disability.
