二手烟对孩子的危害
In their study, the researchers tested blood for a chemical, which is produced when nicotine is metabolized, so they got an objective measure of how much smoke the teenagers were exposed to. They also did ultrasound and other tests to measure blood vessel function and the thickness of the artery wall.
Dr. Kallio agrees with Dr. Lavan that the results support the recommendation that kids be kept away from tobacco smoke.
"The exposure to tobacco smoke is a risk factor for cardiac disease already in adolescents, and that's why this study supports that children and adolescents need smoke-free environments."
Although there is some evidence that artery damage caused by 2nd-hand smoke in adults may be reversible, Lavan says it's unclear whether that's also true for adolescents.
The study was published in the journal "Circulation: Cardiovascular Quality and Outcomes", which is published by the American Heart Association.

在研究中,研究人员对血液进行了可替宁测试。可替宁是尼古丁的代谢产物,这样他们就可以客观地衡量青少年吸入的二手烟的数量。研究人员也采取超声波和其他措施测量血管的功能和动脉血管壁的厚度。
卡里奥医生赞同拉旺医生的研究结果,支持孩子们应远离香烟。
“在青少年中,吸入二手烟已经成为触发心脏疾病的风险因素,这就是研究支持儿童和青少年需要无烟环境的原因。”
尽管已有证据表示,由二手烟引起的成年人血管损伤是可逆的,拉旺表示,还不清楚这对青少年是否同样可行。 |
