Am J Cardiol:使用水烟并不会降低心血管疾病风险

近日,在线发表于《American Journal of Cardiology》杂志上的一项研究表明,抽1.5h的水烟所带来的血管危险因素(心率、血压、动脉硬化程度、血液尼古丁水平升高)与一根普通烟类似。

动脉硬化是高血压进展的主要标志,而高血压增加了心脏疾病、卒中和其他血管疾病的风险。既往的研究显示香烟、无烟烟草、雪茄和电子烟能够导致同样的动脉硬化率,水烟的不良健康结果与之相似。

水烟的市场营销声称水烟对身体的危害相比于普通烟更小,来自加州大学洛杉矶分校护理学院的助理教授Mary Rezk-Hanna及同事检测了48例健康的年轻水烟烟民抽水烟前后30分钟的心率、血压、动脉硬化程度以及一氧化碳的呼出浓度。研究发现,抽一次水烟便可使心率(每分钟增加16次)和血压升高,并可使动脉硬化度显著增加,而动脉硬化是心血管疾病的主要危险因素。动脉硬化度的增加与烟民吸烟后的数据相匹配。

Mary Rezk-Hanna说:“我们知道水烟经常是年轻烟民的首选产品,主要是因为水烟通常是果味、糖果和酒精味道的,这样的味道深受年轻受众的喜欢。”根据《家庭预防吸烟和烟草控制法》授权的FDA的相关规定,普通烟草不能含有人工或天然香料(烟草和薄荷香料除外),或草药香料,但是这样的禁止措施并没有落实到水烟上,因此造成水烟烟民的数量急速增长。

在加利福尼亚,有2000多家商店售卖水烟烟草以及相关的产品,另外还有175家水烟休息室和咖啡馆。洛杉矶的大学校园附近也分布有一定数量的相关场所。美国的全国调查数据显示,在18~24岁的年轻人中,有18.2%的人抽水烟,19.6%的人抽普通烟,8.9%的人抽电子烟。这样的研究结果揭示了水烟使用的下限(0.5h),使用时长能够延续几个小时,潜在地增加了尼古丁和其他有害物被身体吸收的程度,值得我们的关注。

JAMA Pediatrics:水烟危害知多少

JAMA Pediatrics刊文对水烟做出了相关介绍,关注了近年来吸食水烟的情况,并对家长提出了若干建议。 烟草是全球范围内引起死亡和疾病的主要的可控因素。在过去的四十五年中,美国的吸烟率下降因为吸烟对健康的危害越来越明确,室内禁烟,媒体和广告对戒烟的宣传以及人们对烟草危害的认知更多。然而,烟草使用的替代形式,比如水烟的使用正在不断增多。 水烟斗可以使烟从水中通过,并且烟在被吸入肺部之前

Respirology:抽水烟与吸香烟危害一样大

新近发表于Respirology杂志上的研究表明,抽水烟(例如使用水烟筒或者烟枪抽水烟)对肺功能、呼吸道症状的不良影响与吸香烟类似。抽水烟者甚至一些医生一直相信,通过水烟具滤走烟草的若干毒性成份,会使得抽水烟的危害小于吸香烟。水烟具(例如水烟筒)是一种抽水烟的器具,但烟雾在吸入前通过一个水盆(water basin)。为了比较抽水烟者、普通吸香烟者或深吸入香烟者和不吸烟者的肺功能、呼吸道症状,Ma
