A new study has found that teenagers who are exposed to second-hand tobacco smoke are more likely to have changes to their blood vessels that could lead to heart disease later in life.
Researcher Katariina Kallio of the University of Turku in Finland says her study on teenagers extends previous research, which found cardiovascular damage in grown-ups who breathed in other peoples' smoke.
"We know previously that in adults there is that kind of association, but we didn't know that in adolescents," she said in a telephone interview. "So somehow it was a surprise that there is already in adolescents these kinds of changes."
一项新的研究发现，吸入二手烟的青少年更容易发生血管病变，在随后的生活中导致心脏病。
芬兰图尔库大学研究人员Katariina Kallio表示，此前的研究发现吸入二手烟的成年人心脏血管会受到损坏。而她的研究则扩展了以前的研究。
“此前我们知道，二手烟和成年人的心脏血管损坏之间存在联系。但是我们不知道青少年的情况。”她在电话采访中表示。“所以，我们发现吸入二手烟的青少年心脏血管也会发生变化，有点惊讶。”
