AJPM:二手烟危害大!童年接触二手烟增加成年后死于肺病的风险

2018-08-26 浮苏 生物探索

美国相关的统计数据表明:二手烟导致20 -100万患哮喘病的儿童发病次数增加、症状加重。每年约有1900-2700例的婴儿猝死综合症被认为与二手烟污染有关。近日一项研究又表明,儿童长期接触二手烟会增加成年后慢性阻塞性肺疾病(COPD)以及其他几种疾病死亡的风险。



这项研究以“Secondhand Smoke Exposure in Childhood and Adulthood in Relation to Adult Mortality Among Never Smokers”为题发表在《American Journal of Preventive Medicine》杂志。美国癌症协会流行病学研究项目MSPH的Ryan Diver为这项研究的通讯作者。

众所周知,二手烟对儿童和成人的肺和血管系统都有不良影响。但是童年接触二手烟是否会导致成年后的死亡还不清楚。为了探讨这个问题,由MSPH的Ryan Diver领导的美国癌症协会流行病学家研究了癌症预防研究II营养队列(Cancer Prevention Study II Nutrition Cohort)中70,900名从不吸烟的男女儿童和成人二手烟暴露与各种原因导致的死亡、缺血性心脏病、中风和慢性阻塞性肺病的关联。

研究参与者(主要为研究开始时年龄在50-74岁之间的人),回答了关于他们童年和成年时二手烟暴露的问题,并被随访了22年。

结果发现,与未与吸烟者生活在一起的人相比,童年时期与每天吸烟者生活在一起的人发生慢性阻塞性肺疾病的死亡率高出31 %。Diver说,在为此次研究发表所做的计算中,COPD死亡率的增加相当于每年每10万名从不吸烟的参与者中又有7人死亡。

虽然这项研究只计算死亡人数,但致命性COPD的增加意味着童年时与吸烟者一起生活也会增加非致命性COPD的风险。

此外,成年时接触二手烟(每周10个小时或更多)与全因死亡率高9%、缺血性心脏病死亡风险高27%、中风死亡风险高23%和COPD死亡风险高42 %相关。

Diver说:“这是第一个确定儿童接触二手烟与中年及以后慢性阻塞性肺病死亡之间联系的研究。结果同时表明,成人二手烟暴露也会增加COPD死亡的风险。”

“总的来说,我们的发现为减少终生接触二手烟提供了进一步的证据。” Diver总结。
