MMWR CDC Surveill Summ. 2000 Oct 13;49(10):1-94.
PROBLEM/CONDITION: Tobacco use is the single leading preventable cause of death in the United States, accounting for approximately, 430,000 deaths each year. The prevalence of cigarette smoking nationwide among high school students increased during the 1990s, peaking in 1996-1997, then began a gradual decline. Approximately 80% of tobacco users initiate use before the age of 18 years. If the trend in early initiation of cigarette smoking continues, approximately 5 million children aged <18 years who are living today will die prematurely as adults because they began to smoke cigarettes during adolescence. The economic liability associated with tobacco use ranges from $50 billion to $73 billion per year in medical expenses alone. Because of these health and economic consequences, CDC has recommended that states establish and maintain comprehensive tobacco control programs to reduce tobacco use among youth.
February 1998 through December 1999.
To assist states in developing and maintaining their state-based comprehensive tobacco prevention and control programs, CDC developed the Youth Tobacco Surveillance and Evaluation System, which includes international, national, and state school-based surveys of middle school and high school students. Two components of this system are discussed--the National Youth Tobacco Survey and the state Youth Tobacco Surveys. The national survey is representative of students in the 50 states and the District of Columbia; 15,061 students in 131 schools completed questionnaires in 1999. The state surveys were first conducted in 1998, when three states participated, and in 1999, when 13 states participated (13 states conducted middle school surveys and 10 states conducted high school surveys); state sample sizes ranged from 452 to 15,478 students. This report summarizes data from the 1999 national survey and the 1998 and 1999 state surveys.
Findings from the National Youth Tobacco Survey show current tobacco use ranges from 12.8% among middle school students to 34.8% among high school students. Cigarette smoking is the most prevalent form of tobacco used, followed by cigars and smokeless tobacco. Young people have strong cigarette brand preferences. Almost half of current smokers in both middle school and high school report that they usually smoke Marlboro cigarettes. Black students are more likely to smoke Newport cigarettes than any other brand. Half of current smokers in middle school and high school report that they want to completely stop smoking. Nearly one fourth of middle school and high school students who have never smoked cigarettes indicate that they are susceptible to initiating smoking in the next year. Environmental tobacco smoke exposure is very high among both middle school and high school students. During the week before the survey, approximately 9 out of 10 current smokers and half of never smokers were in the same room with someone who was smoking; 8 out of 10 current smokers and 3 out of 10 never smokers rode in a car with someone who was smoking. Six out of 10 current smokers and 3 out of 10 never smokers live in a home where someone else smokes cigarettes. Approximately 70% of middle school and 60% of high school students who currently smoke and are aged <18 years were not asked to show proof of age when they purchased cigarettes. Approximately three fourths of middle school and high school students have seen antismoking commercials; however, 90% report having seen actors smoking on television or in the movies. Approximately 2% of middle school and high school students who had never used tobacco would wear or use something with a tobacco company name or picture on it. This rate increases to approximately 20% for current tobacco users.
Youth Tobacco Survey data are used by health and education officials to improve national and state programs to prevent and control youth tobacco use. (ABSTRACT TRUN
问题/状况:在美国,烟草使用是唯一可预防的首要致死原因,每年约造成43万例死亡。20世纪90年代,全国高中生吸烟率有所上升,在1996 - 1997年达到峰值,随后开始逐渐下降。约80%的烟草使用者在18岁之前开始吸烟。如果青少年过早开始吸烟的趋势持续下去,如今生活着的约500万18岁以下儿童成年后将过早死亡,因为他们在青少年时期就开始吸烟。仅医疗费用方面,与烟草使用相关的经济负担每年就在500亿至730亿美元之间。鉴于这些健康和经济后果,美国疾病控制与预防中心(CDC)建议各州制定并维持全面的烟草控制项目,以减少青少年烟草使用。
1998年2月至1999年12月。
为协助各州制定并维持基于本州的全面烟草预防与控制项目,CDC开发了青少年烟草监测与评估系统,其中包括针对初中和高中学生的国际、全国及各州学校调查。本文讨论该系统的两个组成部分——全国青少年烟草调查和各州青少年烟草调查。全国调查代表了50个州及哥伦比亚特区的学生;1999年,131所学校的15061名学生完成了问卷调查。各州调查于1998年首次开展,当时有3个州参与,1999年有13个州参与(13个州开展了初中调查,10个州开展了高中调查);各州样本量从452名至15478名学生不等。本报告总结了1999年全国调查以及1998年和1999年各州调查的数据。
全国青少年烟草调查结果显示,当前烟草使用率在初中生中为12.8%,在高中生中为34.8%。吸烟是最普遍的烟草使用形式,其次是雪茄和无烟烟草。年轻人对香烟品牌有强烈偏好。初中和高中的当前吸烟者中,近一半表示他们通常吸万宝路香烟。黑人学生比其他任何品牌更倾向于吸新港香烟。初中和高中的当前吸烟者中有一半表示他们想完全戒烟。近四分之一从未吸过烟的初中和高中学生表示他们在明年有可能开始吸烟。初中和高中学生中接触环境烟草烟雾的情况非常普遍。在调查前一周,约十分之九的当前吸烟者和一半的非吸烟者与吸烟者在同一房间;十分之八的当前吸烟者和十分之三的非吸烟者与吸烟者同乘一辆汽车。十分之六的当前吸烟者和十分之三的非吸烟者生活在有人吸烟的家庭中。约70%的初中和60%的高中当前吸烟者且年龄在18岁以下的学生在购买香烟时未被要求出示年龄证明。约四分之三的初中和高中学生看过反吸烟广告;然而,90%的学生报告在电视或电影中看到过演员吸烟。从未使用过烟草的初中和高中学生中,约2%的人会佩戴或使用带有烟草公司名称或标识的物品。对于当前的烟草使用者,这一比例增至约20%。
健康和教育官员利用青少年烟草调查数据来改进国家和各州预防及控制青少年烟草使用的项目。(摘要完)
