绿色社区可减低心脏病发病率

Green neighborhoods could lead to fewer cases of heart disease

      12月5日（UPI 合众国际社）——一项新的研究显示，生活在一个拥有丰富绿地的街区可以降低患心脏病和中风的风险。
      周三《美国心脏协会期刊》上发表的一项新研究显示，居住在离植被较近的人们无论年龄、性别、种族和吸烟状况如何，总体健康质量都较好。
      来自路易斯维尔大学的研究人员检查了血液和尿液样本，以寻找血管损伤生物标志物和心血管疾病风险。路易斯维尔大学的门诊心脏病诊所招募400多名参与者。
      之后，他们使用美国宇航局和美国地质调查局收集的数据，在参与者居住的社区收集植被密度数据，并将其与样本结果进行比较。
      结果显示，居住在靠近茂密植被地区的人的尿中肾上腺素水平较低，表明压力水平较低，尿中F2-异前列腺素水平较低。基于更少的氧化应激并有更高的血管修复能力，这能转变为更好的健康水平。
      Dec. 5 (UPI) -- Living in a neighborhood rich with greenspaces could push down the risk of developing heart disease and stroke, a new study says.
      A new study published Wednesday in the Journal of the American Heart Association reveals that people who live closer to vegetation have an overall better quality of health, regardless of age, sex, ethnicity and smoking status.
      Researchers from the University of Louisville examined the blood and urine samples to look for blood vessel injury biomarkers and cardiovascular disease risk of more than 400 participants recruited from the University of Louisville's outpatient cardiology clinic.
      Then, they gathered vegetation density data from the communities where the participants lived using data collected by NASA and USGS, and compared it to their sample results.
      Specifically, the people who lived closer to the dense vegetation areas had lower urinary levels of epinephrine, indicating lower stress levels, lower urinary levels of F2-isoprostane. This translates to better health,based on less oxidative stress and higher capacity to repair blood vessels.
