概括

通过NDVI测量,居住在绿色空间附近,与孕妇患妊娠糖尿病 (GDM) 的风险较低有关. 空气污染,特别是PM2.5和臭氧,部分介导了这种保护作用.

科学领域:

环境流行病学环境流行病学
公共卫生公共卫生
生殖健康生殖健康

背景情况:

住宅绿地越来越多地被认为具有健康益处.
之前关于绿色空间和妊娠糖尿病 (GDM) 的研究已经产生了不一致的结果.
绿色空间,空气污染和GDM风险之间的相互作用仍然不完全理解.

研究的目的:

调查住宅绿地与GDM风险之间的关联.
探索与GDM相关的绿色空间和空气污染物 (PM2.5,O3) 之间的潜在相互作用.
检查空气污染在绿色空间-GDM协会中的调解作用.

主要方法:

在中国河南46665名孕妇 (2015-2020年) 的回顾性队列研究.
在各种缓冲尺寸 (250m-2000m) 中使用规范差异植被指数 (NDVI) 量化住宅绿地.
空间统计模型估计了NDVI和空气污染;采用多变量逻辑回归和因果调解分析.

主要成果:

第二季度增加的NDVI与所有缓冲区大小 (ORs从0.921到0.922) 的GDM风险降低有关.
在PM2.5,O3暴露和NDVI之间发现了关于GDM风险的显著相互作用 (P<0.001).
在绿色空间和GDM之间的关联中,PM2.5介于2.5-5.5%,O3介于30.1-38.5%.

结论:

住宅绿地,特别是在怀孕的第二个三个月,与GDM发病率较低有关.
绿色空间可能会给GDM带来好处,部分是通过减少对PM2.5和O3的暴露.
调查结果强调了城市绿化对孕产妇健康和减轻空气污染影响的重要性.

Pathophysiology of Diabetes

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Type 2 and Gestational

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
