"人口增長及城市化讓許多人住在繁忙路段附近,大范圍接觸到繁忙交通,老年癡呆病患上升.住在路邊的一般影響也有可能嚴重危及公共健康."
"More research to understand this link is needed, particularly into the effects of different aspects of traffic, such as air pollutants and noise. Around 850,000 people suffer from dementia in Britain, and it is now the leading cause of death for both men and women."
"我們需要做更多研究證明這樣的聯(lián)系,特別是對交通各種不同方面的影響,比方說空氣污染物及噪聲.在英國,約85萬人身患癡呆.癡呆現(xiàn)在已經(jīng)是人們死亡的主要原因之一了."
There has been concern that air pollution could be driving neurodegenerative conditions for many years.
有擔(dān)心者表示,空氣污染很有可能導(dǎo)致多年的神經(jīng)退化.
Last year British scientists discovered tiny magnetic particles produced by car engines and brakes in the brains of people diagnosed with Alzheimer's disease.
去年,英國科學(xué)家在阿爾茲海默癥患者的腦部發(fā)現(xiàn)了汽車發(fā)動機和剎車系統(tǒng)排放出的磁粒子.
In the new study, the team tracked all adults aged between 20 and 85 living in Ontario for more than a decade from 2001 to 2012. They used postcodes to determine how close people lived to a main road and analysed medical records to see if they went on to develop dementia, Parkinson's disease or multiple sclerosis.
最新的這次研究從2001年到2012年跨越10年,研究人員追蹤了住在安大略省的人們,年齡跨度涵蓋20歲到85歲.他們用郵編來確認大家住得離主干道有多近,并進一步分析他們的醫(yī)療記錄,分析他們會不會得老年癡呆、帕金森或者是多發(fā)性硬化.
Over the study period, more than 243,000 people developed dementia, 31,500 people developed Parkinson's disease and 9,250 people developed multiple sclerosis.
在研究過程中,超過24.3萬人患上了老年癡呆,約3.15萬人患上了帕金森,而有9250人得了多發(fā)性硬化.
While there was no association between living near a road and Parkinson's disease or multiple sclerosis, dementia risk reduced as people lived further from a main road, with a 7 percent higher risk in developing dementia among those living within 50 metres; a 4 percent higher risk at 50-100 metres and a 2 percent higher risk at 101-200 metres.
目前還沒有找到住得離繁忙路段遠近和患帕金森或多發(fā)性硬化幾率的聯(lián)系,然而人們住得離主干道越遠,患老年癡呆的幾率就會下降.這些住所離主干道50米之內(nèi)的人患癡呆的幾率會高7%,50-100米內(nèi),幾率會高4%,而距離在101-200米內(nèi)幾率會高2%.
After 200 metres there was no increase.
距離超過兩百米后,就幾乎沒有什么顯著的影響了.
Researchers believe that noise of traffic may also play a role in the raised risk as well as other urban pollution, which is often present near busy roads.
研究者相信交通噪音及其他城市污染也很有可能是導(dǎo)致風(fēng)險增加的原因.這在嘈雜路段非常常見.
