: The aim of this study was to estimate nationally representative prevalence rates of amphetamine-type stimulant (ATS) use and to identify consumption-associated factors, proposing a conditional model of direct and indirect consumption paths.
: Using data from the Second Brazilian National Alcohol and Drugs Survey, this cross-sectional study analyzed a subsample of 3,828 participants between 15 and 64 years old, gathering information on the use of psychoactive substances in a probabilistic sample of the Brazilian household population.
: Rates of lifetime and last-year ATS use were, respectively, 4.1 and 1.6%. Economically privileged individuals and users of other substances were more at risk for using ATS. The results suggest that higher education decreases the chances of ATS consumption. The conditional model showed that higher income increased ATS use, higher education lowered the odds of such an increase, and cocaine use cancelled that associative effect.
: Brazil presents high rates of ATS use. Prevention and treatment strategies should focus on the protective effect of higher education levels and should target polydrug use. Knowledge of ATS-associated factors and user profiles is the starting point for developing effective treatments and tailored prevention strategies.
本研究旨在估算全国具有代表性的苯丙胺类兴奋剂（ATS）使用率，并确定与使用相关的因素，提出一个直接和间接使用途径的条件模型。
利用第二次巴西全国酒精和药物调查的数据，这项横断面研究分析了3828名15至64岁参与者的子样本，在巴西家庭人口概率样本中收集了关于精神活性物质使用的信息。
终生和去年的ATS使用率分别为4.1%和1.6%。经济上享有特权的个人和其他物质使用者使用ATS的风险更高。结果表明，高等教育降低了ATS消费的可能性。条件模型显示，较高收入增加了ATS使用，高等教育降低了这种增加的几率，而可卡因使用消除了这种关联效应。
巴西呈现出较高的ATS使用率。预防和治疗策略应侧重于高等教育水平的保护作用，并应针对多药使用。了解与ATS相关的因素和使用者特征是制定有效治疗方法和量身定制预防策略的起点。
