《中英對照讀新聞》Stress hormone heart death link 壓力荷爾蒙與心臟病死亡相關
◎國際新聞中心High levels of the stress hormone cortisol are closely linked to death from cardiovascular disease, a Dutch study suggests.荷蘭研究顯示,壓力荷爾蒙可體松數值的高升,與因心血管疾病死亡密切相關。

In a six-year study of 860 over-65s, those with the highest levels of cortisol had a five-fold risk of death from cardiovascular disease. No link was found between high cortisol levels and other causes of death.一份針對860名65歲以上民眾的6年研究顯示,可體松高的人,心臟病死亡風險高5倍。可體松數值高與其他死亡原因之間,並未發現關聯。

Cortisol is produced in order to help the body recover from stress and regain its physiological stability. But very high levels have been linked to risk factors for cardiovascualr disease.可體松是為了幫助身體從壓力中恢復,重拾身體穩定度而產生。但是可體松數值爆表,可能是心血管疾病的危險因子。

In this study, researchers measured urinary cortisol levels in each participant. During the six years covered by the study, 183 people died. Cause of death was ascertained from death certificates.在這份研究中,研究人員評估每位參與者尿中的可體松數值,研究涵蓋的6年期間,有183人喪生,死亡證書確定死亡原因。

The third of the subjects with the highest urinary cortisol had a five-fold increased risk of dying of cardiovascular disease.尿中可體松含量最高的3分之1受試者,因心血管疾病死亡的風險增加5倍。新聞辭典urinary:形容詞,尿的,泌尿系統的。如:urinary tract infections 泌尿道感染。-fold: 字尾,……倍。例句:In the last 50 years, there has been a 33-fold increase in the amount of pesticide used in farming.(過去50年間,農耕使用殺蟲劑的量增加了33倍。)
