To report trends in rates of drunkenness, alcohol use, and drug use among Canadian adolescents.
Five national school-based surveys were carried out between 1990 and 2006 as part of the Canadian Health Behaviour in School-aged Children study (n = 4504 to 7010). Students in Grades 6, 8, and 10 were surveyed about the frequency of their drunken episodes and consumption of beer, liquor, and wine. Grade 10 students were also surveyed about their use of drugs.
Rates of drunkenness and alcohol use declined slightly from 1990 to 2006, but about one-half of Grade 10 students in 2006 had used cannabis at least once in their lifetime (up from one-third in 1990). Lifetime prevalence rates of using other drug substances were below 10%.
Timely information on alcohol and drug use among adolescents is important to health policy. Declining trends in alcohol misuse is encouraging; however, the proliferation of cannabis use indicates a need for continued surveillance and education about the risks associated with frequent cannabis use.
报告加拿大青少年酗酒、饮酒和吸毒率的趋势。
1990 年至 2006 年期间，作为加拿大青少年健康行为研究的一部分，进行了五次全国性的基于学校的调查（n=4504 至 7010）。对 6 年级、8 年级和 10 年级的学生进行了关于醉酒频率以及啤酒、白酒和葡萄酒消费频率的调查。10 年级的学生还接受了关于使用毒品的调查。
1990 年至 2006 年期间，酗酒和饮酒率略有下降，但 2006 年约有一半的 10 年级学生至少有过一次使用大麻的经历（1990 年为三分之一）。使用其他药物物质的终身流行率低于 10%。
及时了解青少年的酒精和毒品使用情况对卫生政策很重要。饮酒滥用率呈下降趋势令人鼓舞；然而，大麻使用的扩散表明需要继续监测和教育与频繁使用大麻相关的风险。
