美国年轻人经常接触二手电子烟和烟草烟雾,与易感性增加和持续使用电子烟有关. 减少这种暴露可能有利于公众健康.
科学领域:
- 公共卫生
- 流行病学
- 青少年的健康
背景情况:
- 之前对二手烟暴露和电子烟使用的研究受到间接暴露措施的限制.
- 这项研究通过检查美国年轻人中二手暴露的强有力的指标来解决这个问题.
- 它调查了电子烟和烟草烟雾的使用率和相关性.
研究的目的:
- 确定美国6-12年级学生中二手电子烟和烟草烟雾的患病率.
- 检查二手暴露与电子烟易感性,常用,日常使用和戒烟尝试之间的关联.
- 提供有关二手暴露对青少年电子烟使用行为的公共卫生影响的见解.
主要方法:
- 从2023年全国青少年烟草调查中对21,946名美国6-12年级学生进行横截面分析.
- 参与者根据过去30天的二手暴露情况进行分类:没有,只有电子烟,只有烟草烟雾,或双重暴露.
- 权衡后勤回归模型评估了二手暴露作为电子烟易感性,曾经使用,每日使用和戒烟尝试的预测因素.
主要成果:
- 在过去的30天内观察到大量的二手暴露 (64. 2%,1880万年轻人).
- 接触二手电子烟,烟草烟雾或两者都与电子烟易感性增加有关.
- 二手电子烟和双重暴露与更高的电子烟使用率有关,但不是每日使用或戒烟的尝试.
结论:
- 在美国的年轻人中,二手电子烟和烟雾暴露非常普遍,与早期使用电子烟有关.
- 这些发现表明,减少年轻人接触二手烟可以带来显著的公共健康益处.
- 这项研究强调了处理二手暴露作为及时公众健康挑战的重要性.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
