研究人员从高中校园收集垃圾，以更好地了解青少年吸烟问题

To better understand the vaping epidemic in high schools across the United States, researchers have turned to the ground.

为了更好地了解美国高中电子烟盛行问题，研究人员已经开始实地研究了。

Researchers in Northern California have "systematically scanned the student parking lots and exterior school perimeter areas" to collect e-cigarette, tobacco and cannabis waste on the ground, according to a note published on Thursday in the US Centers for Disease Control and Prevention's Morbidity and Mortality Weekly Report.

美国疾病控制与预防中心的《发病率和死亡率周报》周四发表的一份报告称，北加州的研究人员“系统地查看了学生停车场和学校外围区域”，收集了地上的电子烟、烟草和大麻废弃物。

There were differences in what was found on the ground at schools with a predominantly middle- and upper-income student population compared with schools with a lower-income student population.

调查发现，中等收入和高收入学生为主的学校与低收入学生为主的学校存在差异。

"E-cigarette waste and combustible tobacco product waste contaminate the Bay Area high schools studied and confirm use of these products by high school students," wrote researchers Jeremiah Mock, of the University of California, San Francisco, and Yogi Hendlin, of Erasmus University in the Netherlands, who co-authored the note.

耶利米·莫克写道:“电子烟废弃物和可燃烟草产品废弃物污染了旧金山湾区的高中，并证实了高中生使用这些产品。” 他是旧金山加利福尼亚大学的研究人员，他和荷兰伊拉斯谟大学的约吉·亨德林共同撰写了这份报告。

"Cannabis product waste represents an emerging issue," they wrote.

他们写道:“大麻产品废弃物是一个新问题。”

The note detailed how contamination from e-cigarette product waste, tobacco product waste and cannabis product waste was studied at 12 public high schools in Alameda, Contra Costa, Marin and San Francisco counties between July 2018 and April 2019.

该说明详细说明了2018年7月至2019年4月期间，阿拉梅达、康特拉科斯塔、马林和旧金山县的12所公立高中是如何研究电子烟产品垃圾、烟草产品垃圾和大麻产品垃圾的污染的。

Across those schools, there were a total of 18,831 students enrolled, and overall 893 waste items were collected, among which 19% came from e-cigarette products.

这些学校共有18,831名学生，回收了893件垃圾，其中19%来自电子烟产品。

The researchers conducted additional scans at one school in an upper-income area three months after e-cigarette maker Juul announced it was stopping retail sales of products, except Cool Mint and Classic Menthol.

研究人员额外检查了在高收入地区的一所学校，三个月前，电子烟制造商Juul宣布将停止销售除Cool Mint和Classic Menthol以外的其他产品。

At four high schools with predominantly lower-income students, eight e-cigarette product waste items and 71 little cigar or cigarillo plastic wrappers and mouthpieces were collected, according to the note.

报告称，在四所以低收入学生为主的高中，共收集了8件电子烟产品垃圾和71个小雪茄或小雪茄塑料包装纸和吸嘴。

"The large proportions of flavored products identified in this study are consistent with findings from other studies showing high prevalence rates of e-cigarette and combustible tobacco product use" among youth, Mock and Hendlin wrote in the note.

莫克和亨德林在研究报告中写道:“本研究的结果与其他研究结果有很大比例一致，表明电子烟和可燃烟草产品在青少年中的流行率很高。”

Across all schools, 620 cigarette butts and 14 cannabis product waste items were collected.

在所有学校，共收集了620个烟头和14个大麻产品废弃物。

More than 3.6 million middle and high school studentsin the United States have said that they use e-cigarettes, according to the 2018 National Youth Tobacco Survey. Use of any flavored e-cigarette went up among those young users between 2017 and 2018, rising from 60.9% to 67.8%, and menthol use increased from 42.3% to 51.2%, according to the survey.

根据2018年全国青少年烟草调查，超过360万美国初高中学生表示他们使用电子烟。调查显示，2017年至2018年间，这些年轻用户使用任何口味的电子烟的比例都有所上升，从60.9%升至67.8%，薄荷醇的使用比例从42.3%升至51.2%。

Several states have taken action to prohibit the sale of certain flavored e-cigarette products.

几个州已经采取行动,禁止某些口味的电子烟销售。

The findings in the note are limited to only those high schools in the San Francisco Bay Area, and more research is needed to determine whether similar findings would emerge in other parts of the United States.

报告中的发现仅限于旧金山湾区的高中，还需要更多的研究来确定在美国其他地区是否会有类似的发现。
