Understanding the trends in the prevalence of cigarette smoking among youths enables policy makers to target prevention resources more effectively. Every 2 years, CDC analyzes data from the national Youth Risk Behavior Survey (YRBS) to evaluate trends in cigarette use among high school students in the United States. This report updates a previous report and describes results of CDC's 2010 analysis of YRBS data from 1991-2009 for three measures: ever smoked cigarettes, current cigarette use, and current frequent cigarette use. For ever smoked cigarettes, the prevalence did not change from 1991 (70.1%) to 1999 (70.4%), declined to 58.4% in 2003, and then declined more gradually, to 46.3% in 2009. For current cigarette use, the prevalence increased from 27.5% in 1991 to 36.4% in 1997, declined to 21.9% in 2003, and then declined more gradually, to 19.5% in 2009. For current frequent cigarette use, the prevalence increased from 12.7% in 1991 to 16.8% in 1999, declined to 9.7% in 2003, and then declined more gradually, to 7.3% in 2009. For all three measures, rates began to decline in the late 1990s, but the rate of decline slowed during 2003-2009. To increase the rate of decline in cigarette use among high school students, reductions in advertising, promotions, and commercial availability of tobacco products should be combined with full implementation of communitywide, comprehensive tobacco control programs.
了解青少年吸烟流行趋势使政策制定者能够更有效地将预防资源集中于目标人群。美国疾病预防控制中心（CDC）每两年对全国青少年风险行为监测系统（YRBS）的数据进行分析，以评估美国高中生吸烟趋势。本报告更新了之前的报告，并描述了 2010 年 CDC 对 1991-2009 年 YRBS 数据的分析结果，涉及三个指标：曾经吸烟、当前吸烟和经常吸烟。曾经吸烟的比例从 1991 年的 70.1%（没有变化）到 1999 年的 70.4%，在 2003 年下降到 58.4%，之后下降速度逐渐放缓，在 2009 年下降到 46.3%。当前吸烟的比例从 1991 年的 27.5%增加到 1997 年的 36.4%，在 2003 年下降到 21.9%，之后下降速度逐渐放缓，在 2009 年下降到 19.5%。经常吸烟的比例从 1991 年的 12.7%增加到 1999 年的 16.8%，在 2003 年下降到 9.7%，之后下降速度逐渐放缓，在 2009 年下降到 7.3%。对于所有三个指标，吸烟率在 20 世纪 90 年代末开始下降，但在 2003-2009 年期间下降速度放缓。为了提高高中生吸烟率的下降速度，应减少烟草产品的广告、促销和商业供应，同时全面实施社区综合性控烟项目。
