睡眠与中风


睡眠过多或过少会影响中风的风险,这取决于一个人的种族。
短睡眠定义为六个小时或更少;长睡眠是九小时或更多小时。
研究人员调查了将近17000名白人和黑人,平均年龄64岁,没有中风史。在六年的平均随访中,172名黑人和288名白人共有460次中风。黑人占参与者的37%。
研究结果表明,一半的女性会患痴呆症、中风或帕金森病。
每晚睡眠少于六小时的黑人男性中风几率比普通睡眠者低80%。每晚睡九个小时以上的白人男性中风的风险比普通睡眠者高70%。
结果表明,睡眠量对黑人女性和白人女性的卒中风险没有影响。

研究结果发表在10月3日的《神经病学》杂志上。

      THURSDAY, Oct. 4, 2018 -- Getting too little or too much sleep can affect stroke risk, depending on a man's race, researchers say.
      Short sleep was defined as six hours or less; long sleep was nine or more hours.
      The researchers looked at nearly 17,000 white and black Americans, average age 64, with no history of stroke. During an average follow-up of six years, a total of 460 strokes occurred among 172 blacks and 288 whites. Blacks accounted for 37 percent of the participants.

      Black men who slept less than six hours a night were 80 percent less likely to have a stroke than those who were average sleepers.
      White men who slept nine or more hours a night had a 70 percent higher risk of stroke than those who were average sleepers.
      Amount of sleep had no effect on stroke risk for black or white women, according to the study. The results were published Oct. 3 in the journal Neurology.

      In their analysis, the researchers adjusted for other stroke risk factors such as smoking, diabetes and heart disease. However, the study did not prove a direct cause-and-effect relationship.
