Real-world physical activity patterns in monocular persons have not been previously characterized. This study uses a nationally representative sample to compare the physical activity levels of functionally monocular to binocularly sighted persons in the United States.
This cross-sectional study uses data from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Survey (NHANES) to compare differences in physical activity between functionally monocular and binocular participants. The main outcome measures were accelerometer-measured mean steps per day and mean daily minutes of moderate or vigorous physical activity (MVPA). Statistical analysis was conducted using multivariable negative binomial regression models adjusted for age.
In total, 7967 NHANES participants had complete visual acuity and accelerometer data. The mean age at baseline was 44.5 years, and a majority were Caucasian (73%) and female (51%). In models adjusted for age only, functionally monocular participants (n = 172) took fewer steps (9277 with 95% confidence interval [CI], 8800-9753 vs. 10,057 with 95% CI, 9832-10,281) and engaged in similar minutes of MVPA (26.75 with 95% CI, 22.0-31.5 vs. 26.70 with 95% CI, 25.6-27.7) per day compared to binocularly sighted participants (n = 7758). In our final model, functionally monocular participants took 16% fewer steps per day (P < 0.01) and engaged in 26% fewer minutes per day of MVPA (P = 0.01). Poorer visual acuity, older age, female gender, obesity, congestive heart failure, and arthritis were also associated with a statistically significant decrease in physical activity in both models.
Functionally monocular persons have lower physical activity levels compared to those with binocular eyesight in the United States, even after adjusting for better-eye visual acuity.
Our translational study provides insight into the epidemiology of physical activity and its impact on population health. We quantify real-world physical activity in two at-risk populations, monocular and blind individuals.
目前尚未对单眼人群的实际体力活动模式进行描述。本研究采用全国代表性样本，比较美国单眼和双眼视力正常人群的体力活动水平。
本横断面研究使用 2003-2004 年和 2005-2006 年全国健康与营养调查（NHANES）的数据，比较单眼和双眼功能参与者体力活动的差异。主要观察指标为计步器测量的平均每日步数和平均每日中等强度或剧烈体力活动（MVPA）分钟数。统计分析采用多变量负二项回归模型，根据年龄进行调整。
共有 7967 名 NHANES 参与者完成了视力和加速度计检测。基线时的平均年龄为 44.5 岁，大多数为白种人（73%）和女性（51%）。在仅调整年龄的模型中，单眼功能参与者（n=172）每天的步数较少（9277 步，95%可信区间[CI]：8800-9753 与 10057 步，95%CI：9832-10281），每天进行的中高强度体力活动（MVPA）时间相似（26.75 分钟，95%CI：22.0-31.5 与 26.70 分钟，95%CI：25.6-27.7），与双眼视力正常参与者（n=7758）相比。在最终模型中，单眼功能参与者每天的步数减少 16%（P<0.01），每天的 MVPA 时间减少 26%（P=0.01）。视力较差、年龄较大、女性、肥胖、充血性心力衰竭和关节炎在两个模型中也与体力活动显著减少相关。
与双眼视力正常者相比，美国单眼人群的体力活动水平较低，即使在调整了最佳视力后也是如此。
原文中的“NHANES”为缩写，全称为“National Health and Nutrition Examination Survey”，中文可翻译为“全国健康与营养调查”。
原文中的“MVPA”为缩写，全称为“moderate or vigorous physical activity”，中文可翻译为“中高强度体力活动”。
