一項(xiàng)新的研究發(fā)現(xiàn),大多數(shù)孩子睡眠不足,這可能會導(dǎo)致他們未來罹患心臟病。
Young teens who slept less than seven hours a night tended to have more body fat, elevated blood pressure and less healthy cholesterol levels -- all bad for the heart, researchers say.
研究人員稱,每晚睡眠少于7小時(shí)的青少年身體脂肪多,血壓高,膽固醇水平低--這些都對心臟有害。
Heart disease remains 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.
首席研究員伊麗莎白·塞斯佩德斯·費(fèi)利西亞諾稱,心臟病仍然是頭號殺手。她是加州奧克蘭凱澤北加州研究部的研究員。
"We really want our youth to be on a healthy trajectory," Feliciano said, "and it's a little alarming you would see adverse cardiometabolic profiles emerging even at an age as young as 13."
費(fèi)利西亞諾表示:“我們真的希望我們的年輕人走上健康的軌道。令人有點(diǎn)擔(dān)憂的是,有害的心臟代謝曲線竟能早到13歲時(shí)就出現(xiàn)。”
But it seems that very few kids are getting the kind of nightly slumber that would protect their future heart health.
但似乎很少有孩子能獲得那種能保障他們未來健康的夜間睡眠。
Average sleep duration for kids in the study was only a little over seven hours per day, researchers found.
研究人員發(fā)現(xiàn),這項(xiàng)研究中的孩子,平均每天睡眠時(shí)間只有7個(gè)小時(shí)多一點(diǎn)。
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.
事實(shí)上,只有2.2%的孩子達(dá)到或超過了他們年齡組的平均推薦睡眠時(shí)間:11到13歲的孩子每天要睡9小時(shí),14到17歲的孩子每天要睡8小時(shí)。
"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.
紐約西奈山伊坎醫(yī)學(xué)院的睡眠醫(yī)學(xué)專家安德魯·瓦爾加博士稱:“我真的被這些青少年如此少的睡眠給震撼到了。”
"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."
“考慮到我對孩子和他們的習(xí)慣的了解,這并不是很令人驚訝,但你會認(rèn)為這些孩子會有更多的動(dòng)力去睡覺,因?yàn)樗麄冇泻芨叩乃咝枨蟆?rdquo;
