小孩打呼噜会影响智力
路透社纽约健康消息 研究表明，儿童时曾有打呼噜毛病的孩子，少年时期即使打呼噜已被治愈，仍会出现学习困难。
由路易斯维尔大学大卫·戈扎尔博士和小丹尼斯.W.蒲柏发表在近期《儿科》杂志上的一篇研究报告指出，在班里学习成绩排列在最后1/4的中学生中，幼年时经常大声打呼噜的比例是成绩前1/4的同学的近三倍；而且，名次较后的学生为尝试治疗打呼噜而作过扁桃体和增殖腺切除术的人数是名次较前者的三倍多。
研究人员调查了近1,600名七~八年级公立学校的学生。他们在班上成绩分别处于前1/4或后1/4。成绩在后1/4的学生中约有13%经常大声打呼噜，排在前1/4的学生则只有5%存在这种症状。
研究作者认为，打呼噜提示睡眠时上呼吸道阻力增加。儿童阶段是孩子大脑发育、认知能力与智能快速发展的阶段。睡眠性呼吸困难会破坏睡眠周期，导致孩子注意力不集中、有攻击性和多动症。这些行为障碍均可妨碍孩子的学习。而且，打呼噜也破坏孩子的智力潜能，可能在某种程度上对其学习潜力造成不可逆的危害。
研究还发现，打呼噜还会造成尿床、或发育迟缓。大声打呼噜的孩子有一半多家里有成年人吸烟。研究发现，幼年打呼噜者往往在少年时期会出现哮喘、注意力不集中或多动症、过敏症等。
尽管不知道打呼噜造成的损害是否是永久性的，但至少目前的研究显示，孩子在打呼噜病征治愈后若干年仍残留有学习能力方面的缺陷。因此，如果孩子经常大声打呼噜，应该去看医生，必要时应该考虑看儿科睡眠专科医生。

Child‘s Snoring May Undermine Intellectual Growth
NEW YORK (Reuters Health) - Young children with snoring problems may have academic difficulties into their teens, even after the snoring has stopped, study findings suggest.
The report in the June issue of Pediatrics found that middle-school students ranked in the bottom quarter of their class were nearly three times more likely to have suffered from loud and frequent snoring during early childhood than those in the top quarter of their class. Further, students ranked lower in their class were more than three times more likely to have undergone a surgical procedure known as a tonsillectomy and adenoidectomy in an attempt to cure their snoring.
According to the study authors, snoring is a sign of disordered breathing, which can disrupt sleep cycles and cause difficulty paying attention, aggression and hyperactivity. These types of behavioral problems can interfere with a child‘s academic performance. Snoring can also undermine a child‘s intellectual potential, the report indicates.
``These findings suggest that children who experienced sleep-disordered breathing during a period traditionally associated with major brain growth and substantial acquisition of cognitive and intellectual capabilities may suffer from a partially irreversible compromise of their...potential for academic achievement,‘‘ Dr. David Gozal and Dennis W. Pope Jr. of the University of Louisville in Kentucky, write.
In an interview with Reuters Health, Gozal said that children‘s snoring is never harmless.
``Snoring should always be considered a problem since snoring indicates the presence of increased upper airway resistance during sleep,‘‘ he said. ``I believe that the presence of frequent and loud snoring in children who also demonstrate behavioral problems, learning problems or bedwetting, or failure to thrive, should prompt referral to a primary care physician and strong consideration of an evaluation by a pediatric sleep specialist.‘‘
While it is not clear whether the damage is permanent, Gozal and Pope cite preliminary studies suggesting that recovery of brain capacity is only partial. At the very least, they write, the current study indicates that ``residual deficits in learning performance may still be detected several years after snoring has resolved.‘‘
The researchers interviewed nearly 1,600 seventh- and eighth-grade public school students who were ranked in the top or bottom 25th percentile of their class. Loud, frequent snoring was reported by about 13% of those in the bottom quarter and 5% of those at the top.
Just over 50% of loud snorers lived in a house where an adult smoked. Conditions such as asthma, attention-deficit/hyperactivity disorder and allergies were more likely to occur among teens who snored as children, the investigators found.
