Biol Psychiatry:青少年期吸烟导致注意力缺陷障碍

2015-10-21 candy 译 MedSci原创

背景:吸烟和注意缺陷多动障碍(ADHD)是高度并存的。一个解释是,多动症的患者使用香烟作为“自我药物”,以减轻他们的注意力缺陷的问题。然而,动物研究报告说,在青春期的尼古丁暴露影响大脑发育和对负面影响的关注。这是第一次人类的研究,探索在青春期吸烟对注意力缺陷障碍的影响。方法:吸烟与注意力问题的纵向数据是从注册的荷兰双胞胎中获得,共计1987例成人和648例青少年期的同卵双胞胎。双胞胎根据是否吸烟被

背景:吸烟和注意缺陷多动障碍(ADHD)是高度并存的。一个解释是,多动症的患者使用香烟作为“自我药物”,以减轻他们的注意力缺陷的问题。然而,动物研究报告说,在青春期的尼古丁暴露影响大脑发育和对负面影响的关注。这是第一次人类的研究,探索在青春期吸烟对注意力缺陷障碍的影响。

方法:吸烟与注意力问题的纵向数据是从注册的荷兰双胞胎中获得,共计1987例成人和648例青少年期的同卵双胞胎。双胞胎根据是否吸烟被归类为一致和不一致,并比较其注意力问题。对于成人不一致双胞胎,在吸烟和不吸烟的双胞胎之间的注意力问题上的差异,应注意第一横截面的评估。在纵向分析中,到成年期均不吸烟的双胞胎与不一致的双胞胎。在亚组的纵向数据中,从童年和青春期后,吸烟的一致性和随后的变化对注意力问题的影响进行了探讨。

结果:从青春期到成年都保持吸烟的成年双胞胎较从来没有吸烟的另一位孪生双胞胎有更显著的注意力问题。纵向分析表明,在从青春期到成年均吸烟的双胞胎,较从来没有吸烟的双胞胎有更严重的注意力问题(p < .05)。在儿童和青少年时期吸烟的双胞胎比从来没有吸烟的双胞胎有更多的注意力问题,而在两个双胞胎均开始吸烟的前后,他们的注意力分数是相似的(组间无显著统计学差异)。

结论:从这一基因信息的研究结果表明,青春期吸烟所导致的注意力方面的缺陷,将会持续到成年。

Eur J Nutr:喝红牛,真的好么?

想知道喝一罐红牛或其他能量饮料后24小时内机体会发生哪些变化么?看下去,你就能找到答案。大家往往购买能量饮料是希望有旺盛的精力和强壮的体能。在这些饮料中,咖啡因是最常见的组成成分,但也有其他品牌的饮料含有植物兴奋剂,如瓜拉纳和人参等。根据SAMHSA的要求,能量饮料所允许的咖啡因的含量范围为80-500毫克。相比之下,一杯5盎司的咖啡的咖啡因含量为100mg。能量饮料含糖量也很高。举例而言,一瓶2

JAMA:电子香烟能帮助成年人戒烟,亦能将青少年拉入深渊

电子香烟是一种由电池供电的设备,能够产生可直接吸入的尼古丁气溶胶。制造商和一些公共卫生研究人员认为,这种设备可以为吸烟提供一个健康的选择并且能够帮助吸烟者减少或停止烟草的使用。但同时一些人又存在担忧,因为电子香烟的消费人群常是青少年及年轻的成年人,并且由于经过调味的电子香烟特别能吸引年轻人,很可能导致年轻人对尼古丁成瘾并开始吸烟。   南加州大学的研究人员就青少年电子香烟的使用问题进

Biol Psychiatry:青少年早发性抑郁症影响脑功能网络的正常发展

背景:功能磁共振成像研究表明,成人和青少年的重度抑郁症(MDD)与在静息状态下的默认模式网络(DMN)异常连接有关。情绪失调也是抑郁症的一个重要特征。目前没有探讨与青少年抑郁情绪相关的DMN的病理研究。本研究旨在全面认识抑郁症与暂时性抑郁症的DMN连接的大脑状态的动力学,以洞察抑郁症的病因。方法:我们收集情绪识别任务中和在静息状态下的功能磁共振成像数据,26例未经药物治疗的MDD青少年患者(13–

WHO和UNAIDS发布青少年健康保健新标准

由WHO和UNAIDS发布的青少年质量卫生保健服务全球标准,旨在帮助各国改善青少年健康保健的质量。现有的医疗服务往往不能为世界青少年(10-19岁儿童)提供良好的质量。许多遭受精神健康障碍,物质滥用,营养不良,故意伤害,和慢性疾病的青少年没有获得重要的预防和护理服务。同时,这对健康产生终生影响的许多行为开始于青春期。“这些标准提供了简单而强大的步骤,可以使富裕和贫穷的国家都可以立即采取这些步骤来改

AM J PHYSIOL-HEART C:短时间高强度运动可降低青少年心脏病的发病风险

据埃克塞特大学一项新的研究表明,青少年一周进行3次8-10分钟高强度的间歇性运动可显著减少其心脏病的发病风险。即使是看起来健康的青少年,如此运动后其标志心血管健康的各项指标也会得到显著的改善。目前,通常建议青少年每天应进行60分钟的运动以预防疾病的发生,然而据英国的健康调查显示,不足30%的青少年男性以及20%的青少年女性可达到此运动量。此外,为提高青少年运动水平的各项努力通常以失败告终。因此,探

青少年抽烟导致长期注意力下降

一项研究发现,青春期养成抽烟的习惯会产生一些注意力下降的问题,而这些问题会延续到成年阶段。 “我们的研究所推出的结论旨在强调控制吸烟,尽早戒烟”,该文章的作者,来自荷兰VU大学的博士研究生Jorien Treur说到。 “对于已经产生注意力下降问题的青少年,控制吸烟显得尤为重要。之前的研究告诉我们青少年往往更加容易养成吸烟的习惯,但我们也发现对于已经产生注意力下降问题的青少年,吸烟会导致这
