Abstract

Background: With the accelerating population ageing globally, disability has become a major public concern. Residential greenness may be one of the influencing factors of disability, but epidemiological evidence in the associations of residential greenness exposures with disability is limited. We aimed to investigate the associations of residential greenness exposures with the risk of disability in the elderly.

Methods: Data of 8408 residents were obtained from the World Health Organization Study on Global AGEing and Adult Health (WHO SAGE) implemented in China during 2007-2018. Participants were matched to the Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) at their residential address. Disability was measured by the 12-item Chinese version of the World Health Organization Disability Assessment Schedule (WHODAS 2.0). The associations were examined using a generalized linear mixed model with stratified analyses by the covariates.

Results: We observed significantly negative associations of greenness exposures with the summary WHODAS score [NDVI_500m: -0.290, 95% Confidence Intervals (95%CI): -0.510, -0.070; EVI_500m: -0.453, 95%CI: -0.757, -0.149], and with the score of cognition (EVI_500m: -0.472, 95%CI: -0.881, -0.063), mobility (NDVI_500m: -0.632, 95%CI: -0.965, -0.299; EVI_500m: -0.739, 95%CI: -1.199, -0.280), and participation (NDVI_500m: -0.388, 95%CI: -0.651, -0.125; EVI_500m: -0.530, 95%CI: -0.893, -0.166). People living alone had a more pronounced association in cognition (NDVI_500m: -1.546, 95%CI: -2.471, -0.621). The associations with summary WHODAS score were stronger among participants living in rural areas (NDVI_500m: -0.420, 95%CI: -0.683, -0.157), having less education level (NDVI_500m: -0.618, 95%CI: -0.982, -0.253), and living in northern China (NDVI_500m: -0.381, 95%CI: -0.776, 0.013).

Conclusions: Residential greenness may reduce the onset and worsening of disability, particularly for domains of cognition, mobility, and social participation. Because of its stronger influence among people with low socioeconomic status, increasing greenness levels in areas with lower socioeconomic status may promote health equity.

住宅绿化暴露与残疾的关系：中国全球老龄化与成人健康队列研究（SAGE）的发现。

背景：随着全球人口老龄化加速，残疾问题已成为公众关注的主要问题。居住区绿化可能是残疾的影响因素之一，但居住区绿化暴露与残疾相关的流行病学证据却很有限。我们旨在研究居住区绿化暴露与老年人残疾风险的关系：我们从 2007-2018 年期间在中国开展的世界卫生组织全球老龄化与成人健康研究（WHO SAGE）中获得了 8408 名居民的数据。参与者的居住地址与归一化差异植被指数（NDVI）和增强植被指数（EVI）相匹配。残疾程度采用世界卫生组织残疾评估表（WHODAS 2.0）中文版的 12 个项目进行测量。研究采用广义线性混合模型，并根据协变量进行分层分析：结果：我们观察到绿度暴露与 WHODAS 总分呈明显负相关[NDVI500m：-0.290，95% 置信区间 (95%CI)：-0.510，-0.070；EVI500m：-0.453，95%CI：-0.757，-0.149]，与认知得分呈明显负相关（EVI500m：-0.472，95%CI：-0.881，-0.063）、行动能力（NDVI500m：-0.632，95%CI：-0.965，-0.299；EVI500m：-0.739，95%CI：-1.199，-0.280）和参与能力（NDVI500m：-0.388，95%CI：-0.651，-0.125；EVI500m：-0.530，95%CI：-0.893，-0.166）。独居者在认知方面的关联更为明显（NDVI500m：-1.546，95%CI：-2.471，-0.621）。居住在农村地区（NDVI500m：-0.420，-0.683，95%CI：-0.157）、受教育程度较低（NDVI500m：β=-0.618，95%CI：-0.982，-0.253）和居住在中国北方（NDVI500m：β=-0.381，95%CI：-0.776，0.013）的参与者与 WHODAS 总分的相关性更强：住宅绿化可减少残疾的发生和恶化，尤其是在认知、行动能力和社会参与方面。由于绿化对社会经济地位较低人群的影响更大，在社会经济地位较低的地区提高绿化水平可能会促进健康公平。
