Approximately three million U.S. adolescents are smokers, and they smoke nearly one billion packs of cigarettes each year. The average age at which smokers try their first cigarette is 14 1/2 years, and approximately 70% of smokers become regular smokers by age 18 years. Evaluating the changes in the brand preferences of young smokers can help identify factors that influence adolescents' brand choice and may suggest smoking-prevention strategies. This report examines changes in the brand preferences of teenaged smokers from 1989 to 1993 using data from CDC's 1993 Teenage Attitudes and Practices Survey (TAPS-II) and comparing them with data from the 1989 TAPS.
美国约有三百万青少年吸烟，他们每年吸食近十亿包香烟。吸烟者首次尝试吸烟的平均年龄为14.5岁，约70%的吸烟者在18岁时成为经常吸烟者。评估年轻吸烟者品牌偏好的变化有助于确定影响青少年品牌选择的因素，并可能提出预防吸烟的策略。本报告利用疾病控制与预防中心1993年青少年态度与行为调查（TAPS-II）的数据，研究了1989年至1993年青少年吸烟者品牌偏好的变化，并将其与1989年TAPS的数据进行了比较。
