To estimate the prevalence and frequency of amphetamine use in a cohort of Australians aged in their mid-30s.
Cross-sectional analysis of wave 10 data collected in 2014 from the Victorian Adolescent Health Cohort Study: a sample of 1435 persons originally selected in a stratified, random community survey of secondary school students from the state of Victoria that commenced in 1992. Weighted multinomial regression models were used to evaluate the social, health and other substance-use correlates of lifetime and current (12-month) amphetamine use and current frequency of use.
Lifetime amphetamine use was reported by 23.2% (95% confidence interval 21.0-25.5%) of respondents, and 6.5% (95% confidence interval 5.2-7.8%) reported current (12-month) use. A quarter (26%) of those currently using amphetamines, 1.7% (95% confidence interval 1.0-2.4%) of all respondents, reported frequent (at least weekly) use. Men reported greater amphetamine use than women. Current amphetamine use was associated with disrupted family circumstances, socioeconomic adversity, polydrug use and high levels of drug use within the social and familial environment. Frequent use was associated with greater likelihood of multiple adversity, unemployment, anxiety disorders and use of mental health services.
The current results show that lifetime, current and frequent amphetamine use was common amongst adults in the fourth decade of life in this cohort, and associated with the experience of social disadvantage, poor mental health and living in a social context in which drug use is the norm.
评估在一个年龄在 30 多岁的澳大利亚人群中安非他命使用的流行率和频率。
2014 年对维多利亚青少年健康队列研究的第 10 波数据进行横断面分析：该研究是对维多利亚州中学学生进行分层随机社区调查中选择的 1435 人的样本，该调查于 1992 年开始。使用加权多项回归模型评估终生和当前（12 个月）安非他命使用以及当前使用频率的社会、健康和其他物质使用相关因素。
23.2%（95%置信区间 21.0-25.5%）的受访者报告有终生安非他命使用，6.5%（95%置信区间 5.2-7.8%）报告有当前（12 个月）使用。目前使用安非他命的人中，有四分之一（26%），即所有受访者的 1.7%（95%置信区间 1.0-2.4%）报告了频繁（至少每周）使用。男性报告的安非他命使用量多于女性。当前安非他命使用与家庭环境破裂、社会经济劣势、多药使用以及社交和家庭环境中较高的药物使用水平有关。频繁使用与更多逆境、失业、焦虑障碍和使用心理健康服务的可能性更大有关。
目前的结果表明，在该队列中，第四十年的成年人中，终生、当前和频繁使用安非他命很常见，并且与社会劣势、心理健康不良以及生活在药物使用为常态的社会环境有关。
