Most kids don't get enough sleep, and that may put them on a path to future heart trouble, a new study finds.

一项新的研究发现，大多数孩子睡眠不足，这可能会导致他们未来罹患心脏病。

Young teens who slept less than seven hours a night tended to have more body fat, elevated blood pressure and less healthy cholesterol¹ levels -- all bad for the heart, researchers say.

研究人员称，每晚睡眠少于7小时的青少年身体脂肪多，血压高，胆固醇水平低--这些都对心脏有害。

Heart disease remains² a leading killer, said lead researcher Elizabeth Cespedes Feliciano. She's a staff scientist with the Kaiser Permanente Northern California Division of Research in Oakland, Calif.

首席研究员伊丽莎白·塞斯佩德斯·费利西亚诺称，心脏病仍然是头号杀手。她是加州奥克兰凯泽北加州研究部的研究员。

"We really want our youth to be on a healthy trajectory," Feliciano said, "and it's a little alarming you would see adverse³ cardiometabolic profiles emerging even at an age as young as 13."

费利西亚诺表示：“我们真的希望我们的年轻人走上健康的轨道。令人有点担忧的是，有害的心脏代谢曲线竟能早到13岁时就出现。”

研究发现 睡眠不足的少年更易患心脏疾病

But it seems that very few kids are getting the kind of nightly slumber⁴ that would protect their future heart health.

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。”
