Sleep is essential for overall health. Greenspace may contribute to sleep health through, for instance, improving mood, reducing sleep disruptors (e.g., poor air quality), and promoting physical activity. Although greenspace likely differs across populations, few studies have included diverse populations. To investigate greenspace-sleep health associations, overall and by age, race and ethnicity, and socioeconomic status, we used data collected at enrollment (2003-2009) from women in the Sister Study (n = 1612 Hispanic/Latina, n = 4421 non-Hispanic (NH)-Black, and n = 41,657 NH-White). Participants' geocoded home addresses were linked to NASA's Moderate Resolution Imaging Spectroradiometer Normalized Difference Vegetation Index data (250m resolution) to capture greenspace tertiles (further categorized as low/moderate vs. high). Participants reported seven sleep dimensions, which we assessed individually, along with a multidimensional sleep health measure (categories: favorable, moderate, poor). Adjusting for individual- and environmental/neighborhood-level characteristics, we used Poisson regression with robust variance to estimate prevalence ratios and 95 % confidence intervals (PR[CI]). We tested for interaction and estimated age-, race and ethnicity-, and educational attainment category-specific associations. Among participants (mean ± SD age = 55.7 ± 9.0 years), those with low/moderate vs. high greenspace had a lower prevalence of favorable sleep (58 % vs. 66 %). After adjustment, low/moderate vs. high greenspace was associated with a 32 % higher prevalence of moderate (PR = 1.32 [1.27-1.38]) and 12 % higher prevalence of poor (PR = 1.12 [1.07-1.16]) vs. favorable sleep health. Magnitudes of associations were higher among NH-White women vs. minoritized racial-ethnic groups and women with higher vs. lower educational attainment. Higher greenspace was associated with favorable sleep, with stronger associations among groups with more social advantages.
睡眠对整体健康至关重要。绿地空间可能通过改善情绪、减少睡眠干扰因素（如空气质量差）以及促进体育活动等方式，对睡眠健康有所助益。尽管不同人群的绿地空间情况可能有所不同，但很少有研究纳入了多样化的人群。为了研究绿地空间与睡眠健康之间的关联，包括总体关联以及按年龄、种族和族裔、社会经济地位划分的关联，我们使用了姐妹研究中（2003 - 2009年）女性在入组时收集的数据（n = 1612名西班牙裔/拉丁裔、n = 4421名非西班牙裔黑人以及n = 41657名非西班牙裔白人）。参与者经地理编码的家庭住址与美国国家航空航天局的中分辨率成像光谱仪归一化植被指数数据（250米分辨率）相关联，以获取绿地空间三分位数（进一步分为低/中度与高度）。参与者报告了七个睡眠维度，我们分别对其进行评估，同时还有一项多维睡眠健康指标（类别：良好、中等、较差）。在对个体及环境/邻里层面的特征进行调整后，我们使用稳健方差的泊松回归来估计患病率比和95%置信区间（PR[CI]）。我们检验了交互作用，并估计了特定年龄、种族和族裔以及教育程度类别的关联。在参与者中（平均年龄±标准差 = 55.7 ± 9.0岁），绿地空间为低/中度与高度的人群相比，睡眠良好的患病率较低（分别为58%和66%）。调整后，与绿地空间高度相比，低/中度绿地空间与睡眠健康为中等的患病率高32%（PR = 1.32 [1.27 - 1.38]）以及睡眠健康较差的患病率高12%（PR = 1.12 [1.07 - 1.16]）相关。非西班牙裔白人女性与少数族裔群体相比，以及教育程度较高与较低的女性相比，关联程度更高。绿地空间越高与睡眠良好相关，在具有更多社会优势的群体中关联更强。
