对物质使用和物质使用障碍的流行病学研究提供了关于世界各国代表性样本中物质使用模式的丰富数据。本文提出了一个总结的目标,方法和最近的研究结果,在一般人群的成年人和青少年的物质使用和疾病的流行病学,并介绍了药物使用疾病的遗传流行病学的方法和研究结果。美国成年人中物质依赖的12个月高流行率(酒精约为12%,非法药物约为2-3%)与其他精神疾病以及对公共卫生有重大影响的慢性身体疾病相似。来自美国青年全国代表性样本的新发现显示,酒精使用障碍的终生患病率约为8%,非法药物使用障碍为2-3%(,SAMSHA,2011)。13至18岁的流行率显著增加,突出表明青春期是吸毒疾患发展的关键时期。遗传流行病学研究的应用一贯表明,遗传因素对药物使用发展成依赖性有重大影响,而个人特有的环境因素在接触和初次使用药物方面起着重要作用。识别影响药物使用暴露和进展的特定易感基因和环境因素可能会增强我们预防和治疗物质使用障碍的能力。
Epidemiological studies of substance use and substance use disorders (SUDs) have provided an abundance of data on the patterns of substance use in nationally representative samples across the world. This paper presents a summary of the goals, methods and recent findings on the epidemiology of substance use and disorders in the general population of adults and adolescents and describes the methods and findings on the genetic epidemiology of drug use disorders. The high 12 month prevalence rates of substance dependence in U.S. adults (about 12% for alcohol and 2–3% for illicit drugs) approximate those of other mental disorders as well as chronic physical disorders with major public health impact. New findings from the nationally representative samples of U.S. youth reveal that the lifetime prevalence of alcohol use disorders is approximately 8% and illicit drug use disorders is 2–3% (, SAMSHA, 2011). The striking increase in prevalence rates from ages 13 to 18 highlight adolescence as the key period of development of substance use disorders. The application of genetic epidemiological studies has consistently demonstrated that genetic factors have a major influence on progression of substance use to dependence, whereas environmental factors unique to the individual play an important role in exposure and initial use of substances. Identification of specific susceptibility genes and environmental factors that influence exposure and progression of drug use may enhance our ability to prevent and treat substance use disorders.
