但似乎很少有孩子能获得那种能保障他们未来健康的夜间睡眠。
Average sleep duration for kids in the study was only a little over seven hours per day, researchers found.
研究人员发现,这项研究中的孩子,平均每天睡眠时间只有7个小时多一点。
In fact, only 2.2 percent of the kids met or exceeded the average recommended sleep duration for their age group -- nine hours per day for kids 11 to 13 and eight hours per day for teens 14 to 17.
事实上,只有2.2%的孩子达到或超过了他们年龄组的平均推荐睡眠时间:11到13岁的孩子每天要睡9小时,14到17岁的孩子每天要睡8小时。
"I was really struck by how little these adolescents are sleeping," said Dr. Andrew Varga, a sleep medicine specialist with the Icahn School of Medicine at Mount Sinai in New York City.
纽约西奈山伊坎医学院的睡眠医学专家安德鲁·瓦尔加博士称:“我真的被这些青少年如此少的睡眠给震撼到了。”
"It's not totally surprising, given what I know about kids and their habits, but you would think there would be some drive for these kids to sleep more because they have a high sleep need."
“考虑到我对孩子和他们的习惯的了解,这并不是很令人惊讶,但你会认为这些孩子会有更多的动力去睡觉,因为他们有很高的睡眠需求。”
