接触绿色被认为是一个潜在的有益健康的因素，但关于它对糖尿病的影响的证据有限。2016年5月至9月，我们在中国西北农村地区进行了一项横断面研究，包括4670名维吾尔族成年人，以探索住宅绿化与空腹血糖水平和糖尿病患病率之间的关系。测定空腹血糖水平，并通过问卷收集协变量信息。计算归一化植被指数（NDVI）和土壤调整植被指数（SAVI）来评价绿化水平。应用广义线性混合模型来评估绿度与空腹血糖水平和糖尿病患病率之间的关系。糖尿病患病率为11.6%。我们发现，生活在以绿化数量增加为特征的农村地区与糖尿病患病率降低相关（例如，NDVI1000m: OR, 0.92; 95% CI, 0.86, 0.99）。分层分析显示，绿化对糖尿病患病率的保护作用仅在女性中发现（NDVI1000m: OR, 0.90; 95% CI, 0.82, 0.99）。然而，这些相互作用都没有统计学意义。我们的研究表明，居住绿化水平越高，新疆维吾尔族成年人糖尿病患病率的比值比越低。需要进一步精心设计的纵向研究来证实我们的发现。
Greenness exposure is nominated as a potential beneficial factor for health, but evidence is limited on its diabetes effects. We conducted a cross-sectional study between May and September 2016 in rural areas of northwestern China, including 4670 Uyghur adults, to explore the associations between residential greenness and fasting glucose levels and diabetes prevalence. Fasting glucose levels were determined, and information on covariates was collected by questionnaire. Normalized difference vegetation index (NDVI) and soil-adjusted vegetation index (SAVI) were calculated to assess greenness levels. Generalized linear mixed models were applied to evaluate the associations of greenness with fasting glucose levels and diabetes prevalence. The prevalence of diabetes was 11.6%. We found that living in rural areas characterized by increased amounts of greenness was associated with reduced diabetes prevalence (e.g., NDVI1000m: OR, 0.92; 95% CI, 0.86, 0.99). Stratified analyses showed that the protective effects of greenness on diabetes prevalence were found only in women (NDVI1000m: OR, 0.90; 95% CI, 0.82, 0.99). However, none of the interaction was statistically significant. Our study suggests that greater residential greenness levels were associated with a lower odds ratio of diabetes prevalence in Xinjiang Uyghur adults. Further well-designed longitudinal studies are needed to confirm our findings.
