目的：研究酒精、烟草、大麻、安非他明的使用流行率和开始使用年龄的出生队列趋势。LSD和海洛因。方法：数据来自1998年全国毒品战略家庭调查，这是一项对14岁及以上的澳大利亚人的代表性样本的调查。在1940年至1984年之间出生的人中，研究了9个为期5年的队列。估计了15岁、21岁和终身使用的加权使用率，以及用户首次使用的平均年龄。使用逻辑回归（终身使用、15年和21年使用）和线性回归（首次使用年龄）检验趋势的显著性。结果：所有出生队列的终生酒精和烟草使用患病率相似。非法药物使用- -大麻、安非他明、迷幻药和海洛因- -的流行率随着连续出生队列的增加而增加，最近出生队列报告使用合法和非法药物的年龄更小。结论：最近的队列更有可能在其生命的某个阶段使用非法药物。来自较晚出生队列的更多的人可能面临发生物质相关问题的风险。
Aim: To examine birth cohort trends in the prevalence of use and the age of initiation of use of: alcohol, tobacco, cannabis, amphetamines. LSD, and heroin.Method: Data were taken from the 1998 National Drug Strategy Household Survey, a survey of a representative sample of Australians aged 14 years and over. Nine five-year cohorts were examined among persons born between 1940 and 1984. The weighted prevalence of use by ages 15 years, 21 years, and lifetime use, was estimated, as was the average age of first use among users. The significance of trends was tested using logistic regression (for lifetime use, use by 15 and 21 years) and linear regression (for age of first use).Results: Lifetime prevalence of alcohol and tobacco use was similar among ail birth cohorts. The prevalence of illicit drug use - cannabis, amphetamines, LSD and heroin - increased with successive birth cohorts and more recent birth cohorts reported using licit and illicit drugs at a younger age.Conclusions: More recent cohorts are move likely to use illicit drugs at some point in their lives. Greater numbers of persons from more recent birth cohorts may be at risk of developing substance-related problems.
