Abstract：
Despite known benefits of engaging in recommended amounts of physical activity (PA), sleep, and sedentary behavior (SB), little is known about how adults with visual impairments (VIs) meet these guidelines in isolation or simultaneously.
This study estimated (a) the prevalence of US adults with VIs who are partially or fully meeting the 24-h movement guidelines, and (b) the differential contribution of work-related, leisure, and transportation to total time accrued for PA.
A cross-sectional sample of adults with VIs (n = 466) was drawn from the National Health and Nutritional Examination Survey (NHANES) 2015-2018 combined datasets. Guideline adherence was measured using self-report items for average time spent physically active, sitting and sleeping. Weighted prevalence estimates were produced for meeting guidelines separately and in combination. The average percent of PA minutes accrued across work-related, leisure and transportation were compared among those meeting PA guidelines.
An estimated 29.6% (SE = 3.6) of US adults with VIs met all three guidelines. An estimated 59.3% (SE = 3.5) adults with VIs met PA guidelines alone or in combination with SB and sleep. Within this group, the majority of weekly PA minutes (average 63.9%) was accrued at work.
An estimated two thirds of adults with VIs are not engaged in healthful 24-h movement behaviors. Targeted interventions for adults with VIs are warranted that may require a comprehensive approach to PA, SB, and sleep. Work emerged as an important location for adults with VIs to accrue PA, inviting future research to explore associations between employment and 24-h movements within this population.

摘要：
尽管已知进行推荐量的身体活动（PA）的好处，睡眠,和久坐行为(SB)，对于患有视觉障碍(VI)的成年人如何孤立或同时满足这些指南，人们知之甚少。
这项研究估计了（a）美国成年人中部分或完全符合24小时运动指南的VIs的患病率，和(b)与工作有关的不同贡献，休闲,和运输到PA累计总时间。
从2015-2018年国家健康和营养检查调查（NHANES）合并数据集中抽取了患有VIs的成年人的横截面样本（n=466）。指南依从性是使用自我报告项目测量的平均体力活动时间，坐着睡觉。产生加权患病率估计值以单独和组合满足指南。与工作相关的PA分钟累积的平均百分比，在符合PA指南的人群中比较了休闲和交通。
估计有29.6%（SE=3.6）的美国成年人符合所有三个指南。估计有59.3％（SE=3.5）的VI成年人单独或与SB和睡眠组合符合PA指南。在这个群体中,大部分每周PA分钟(平均63.9%)是在工作中累积的.
估计有三分之二的成年人没有从事健康的24小时运动行为。有针对性的干预措施对成人的VIs是必要的，可能需要对PA采取全面的方法，SB,和睡眠。工作成为拥有VIs的成年人积累PA的重要场所，邀请未来的研究来探索就业和24小时运动之间的关联在这个人群中。
