Studies support assertions that more social support may be related to higher physical activity behavior, which may, in turn, relate to higher health-related quality of life (HRQoL). However, these relationships remain unexplored, particularly among adults with visual impairments.
The purpose of this study was to examine the relationships between physical activity-specific social support, physical activity participation, and HRQoL among adults with visual impairments.
This cross-sectional study utilized an online survey methodology. Adults with visual impairments (n = 251) were recruited via three visual impairment LISTSERVs housed in the USA and completed four questionnaires. Data were analyzed using (a) a descriptive analysis, (b) one sample t-test, and (c) structural equation modeling to examine the relations among social support, physical activity, and HRQoL components.
The participants reported relatively low weekly physical activity participation, with mean physical activity about 1362.02 ± 1231.37 MET-min/week. Compared to the mean T-scores of the general adult US population, the participants had significantly lower physical (43.56 ± 6.76, t = -15.10, p < .01) and mental components of HRQoL (38.24 ± 11.37, t = -16.39, p < .01). Structural equational modeling results show that social support positively predicted weekly physical activity participation (β = 0.11), which, in turn, predicted physical component (β = 0.12) but not mental component HRQoL (β = 0.04, p > .05).
Our participant sample reported significantly lower HRQoL than the general US populations. The findings suggest that social support can both directly and indirectly, through physical activity, influence psychological HRQoL among adults with visual impairments.
研究支持这样的观点，即更多的社会支持可能与更高的身体活动行为有关，而身体活动行为反过来又可能与更高的健康相关生活质量（HRQoL）有关。然而，这些关系尚未得到探索，特别是在视力障碍的成年人中。
本研究旨在探讨视力障碍成年人中身体活动特定社会支持、身体活动参与度和 HRQoL 之间的关系。
本横断面研究采用在线调查方法。通过美国的三个视力障碍 LISTSERV 招募视力障碍成年人（n=251），并完成了四个问卷。使用（a）描述性分析、（b）单样本 t 检验和（c）结构方程模型来分析社会支持、身体活动和 HRQoL 成分之间的关系。
参与者每周的身体活动参与度相对较低，平均身体活动量约为 1362.02±1231.37 MET-min/周。与美国一般成年人口的平均 T 分数相比，参与者的身体（43.56±6.76，t=-15.10，p<.01）和精神（38.24±11.37，t=-16.39，p<.01）HRQoL 成分明显较低。结构方程模型结果表明，社会支持正向预测每周身体活动参与度（β=0.11），而身体活动参与度又正向预测身体成分（β=0.12）但不预测心理成分 HRQoL（β=0.04，p>.05）。
我们的参与者样本报告的 HRQoL 明显低于美国一般人群。研究结果表明，社会支持既可以直接影响视力障碍成年人的心理 HRQoL，也可以通过身体活动间接影响。
