Tobacco use is the single leading preventable cause of death in the United States, and the risk for smoking-attributable disease increases the earlier in life smoking begins. Trends in the initiation of cigarette smoking are important indicators for directing and evaluating prevention activities. CDC and the Substance Abuse and Mental Health Services Administration (SAMHSA) analyzed self-reported data from the National Household Survey on Drug Abuse (NHSDA) for 1994-1997 to study the incidence of initiation of first cigarette smoking and of first daily smoking in the United States during 1965-1996 among persons aged < or =66 years and to estimate the number of new smokers aged <18 years. The findings from the analysis indicated that, during 1988-1996 among persons aged 12-17 years, the incidence of initiation of first use increased by 30% and of first daily use increased by 50%, and 1,226,000 persons aged <18 years became daily smokers in 1996.
在美国，吸烟是单一的首要可预防死因，而且吸烟引发疾病的风险会随着开始吸烟年龄的提前而增加。吸烟起始趋势是指导和评估预防活动的重要指标。美国疾病控制与预防中心（CDC）及药物滥用和精神健康服务管理局（SAMHSA）分析了1994 - 1997年全国药物滥用家庭调查（NHSDA）中的自我报告数据，以研究1965 - 1996年期间美国66岁及以下人群首次吸烟和首次每日吸烟的发生率，并估算18岁以下新吸烟者的数量。分析结果表明，在1988 - 1996年期间，12 - 17岁人群中，首次使用香烟的发生率上升了30%，首次每日吸烟的发生率上升了50%，并且在1996年有122.6万名18岁以下的人成为了每日吸烟者。
