Although previous studies have shown detrimental effects of visual impairment on health-related quality of life (HRQOL), they were primarily conducted on elderly individuals with visual impairment. The objective of this cross-sectional study was to investigate if HRQOL is impaired in young college students with visual impairment and to explore the relationships between HRQOL and other factors. It was hypothesized that visual impairment is not influential enough to lower the HRQOL of young people due to their better physical fitness and more flexible mentality.
A total of 21 college students (mean age = 25 years old) with varying degrees of visual impairment completed the short form (SF)-36 health survey and questionnaires on daily physical activities. Subjects were grouped depending on the type of visual impairment: blind (n = 11) or severely impaired (n = 10). In addition, grip strength and single-leg standing balance were assessed.
No between-group differences were found in the SF-36 scores. However, compared to the general Japanese standards (50.0 ± 10.0), the Vitality scores of the blind group were lower (41.9 ± 7.2, p = 0.004) and the Physical Function scores of the severely impaired group were higher (55.3 ± 2.4, p = 0.001). In addition, a negative correlation was found between standing balance (variability of foot center of pressure) and the Physical Component Summary score of the SF-36 (r(2) = 0.35, p = 0.005).
These findings suggest that even among young people severe visual impairment leads to reductions in some components of HRQOL.
尽管先前的研究已表明视力障碍对健康相关生活质量（HRQOL）有不利影响，但这些研究主要针对有视力障碍的老年人。这项横断面研究的目的是调查视力障碍的年轻大学生的HRQOL是否受损，并探讨HRQOL与其他因素之间的关系。研究假设是，由于年轻人身体素质更好、心态更灵活，视力障碍对他们降低HRQOL的影响不够大。
共有21名不同程度视力障碍的大学生（平均年龄 = 25岁）完成了简短形式（SF）-36健康调查以及关于日常体育活动的问卷。受试者根据视力障碍类型分组：失明（n = 11）或重度视力障碍（n = 10）。此外，还评估了握力和单腿站立平衡能力。
SF-36评分在组间未发现差异。然而，与日本一般标准（50.0±10.0）相比，失明组的活力得分较低（41.9±7.2，p = 0.004），重度视力障碍组的身体功能得分较高（55.3±2.4，p = 0.001）。此外，发现站立平衡能力（足底压力中心的变异性）与SF-36的身体成分总结得分之间存在负相关（r(2)=0.35，p = 0.005）。
这些发现表明，即使在年轻人中，严重视力障碍也会导致HRQOL的某些组成部分下降。
