目的：确定巴西有代表性的人群中可卡因使用和依赖的流行程度，并调查可能与社会人口学因素有关的因素。方法：第二次巴西酒精和毒品调查(II BNADS)访问了巴西家庭人口中4607名14岁及以上的人，其中包括1157名14至18岁的青少年。这项调查收集了有关酒精、烟草和非法物质使用以及滥用和依赖的风险因素的信息。用依赖严重程度量表评价吸毒者的可卡因依赖率。结果：去年吸食强效可卡因的人群中，除老年人群外，吸食强效可卡因的比例为22%。终生吸食可卡因的患病率为3.9%，去年吸食可卡因的患病率为1.7%。据估计，巴西终生吸食可卡因的比例为15%，去年吸食可卡因的比例为0.8%。前一年吸毒者的可卡因成瘾率为41.4%。结论：巴西吸食可卡因和吸食可卡因的流行率表明，巴西是年吸食可卡因最多的国家之一，成为全球最大的可卡因消费市场之一。预防和治疗政策应考虑到这一点，并加强对该国可卡因使用的关注。(C)2013爱思唯尔有限公司。保留所有权利。
Objective: To determine the current prevalence rates of cocaine use and dependence in a representative sample of the Brazilian population, and to investigate possible associations with sociodemographic factors.Method: The Second Brazilian Alcohol and Drugs Survey (II BNADS) interviewed 4607 individuals aged 14 years and older from the Brazilian household population including an oversample of 1157 adolescents (14 to 18 years old). The survey gathered information on alcohol, tobacco and illegal substances use as well as on risk factors for abuse and dependence. The Severity of Dependence Scale was used to evaluate cocaine dependence rates among users.Results: Last year consumption of crack-cocaine was 22% in the overall population excluding the elderly group. Lifetime and last year prevalence rate of snorted cocaine was 3.9% and 1.7%, respectively. Smoked cocaine use in Brazil was estimated in 15% for lifetime and 0.8% for last year use. Cocaine addiction was identified in 41.4% between users in the prior year.Conclusions: The prevalence rates of snorted and smoked cocaine in Brazil suggests that the country is amongst the nations with greatest annual consumption rates becoming one of the biggest consumer markets of cocaine worldwide. Prevention and treatment policies should take this into consideration and strengthen the focus on cocaine use in the country. (C) 2013 Elsevier Ltd. All rights reserved.
