To describe the prevalence of smoking in junior secondary school students in Hong Kong and to analyse the relationship between a range of risk factors and ever-smoking experience, including tobacco advertisements.
Cross-sectional survey using an anonymous standardised self-administered questionnaire.
61 randomly selected secondary schools in Hong Kong.
6,304 form 1 to 3 Chinese students from 172 classes (51% girls and 49% boys; 90% were aged 12 to 15 years).
The smoking status (95% confidence interval) was: (1) never smoker, 71.1% (70.0%-72.2%), (2) tried only, 15.5% (14.6%-16.4%), (3) used to smoke but not now, 4.2% (3.7%-4.7%), (4) smoked < 1 cigarette per week, 2.9% (2.5%-3.4%), (5) smoked 1-6 per week, 1.7% (1.4%-2.0%), and (6) smoked > 6 per week, 4.5% (4.0%-5.0%). In a backward stepwise logistic regression model, ever-smoking (including categories 2 to 6 above) was independently associated with thirteen factors, including gender (boys), increasing age, place of birth (outside Hong Kong, mainly China), poor knowledge of the hazards of smoking, positive attitudes to smoking, smoking in family members, participation in tobacco promotional activities, and perception of cigarette advertisements as attractive. Among the strongest associations observed was the youth's perception of cigarette advertisements as attractive, with the adjusted odds ratio (95% confidence interval) of 2.68 (2.33-3.07).
Smoking among young people is an important public health problem. Although the causes are multifactorial, in Hong Kong environmental tobacco advertising is an important risk factor that can be removed by banning all forms of tobacco promotion to young people.
描述香港初中学生的吸烟率，并分析一系列风险因素与曾经吸烟经历之间的关系，包括烟草广告。
采用匿名标准化自填问卷进行横断面调查。
香港61所随机选取的中学。
来自172个班级的6304名中一至中三的中国学生（女生占51%，男生占49%；90%的学生年龄在12至15岁之间）。
吸烟状况（95%置信区间）如下：（1）从不吸烟者，71.1%（70.0%-72.2%）；（2）仅尝试吸烟者，15.5%（14.6%-16.4%）；（3）曾经吸烟但现在不吸者，4.2%（3.7%-4.7%）；（4）每周吸烟少于1支者，2.9%（2.5%-3.4%）；（5）每周吸烟1-6支者，1.7%（1.4%-2.0%）；（6）每周吸烟超过6支者，4.5%（4.0%-5.0%）。在向后逐步逻辑回归模型中，曾经吸烟（包括上述第2至6类）与13个因素独立相关，包括性别（男生）、年龄增长、出生地（香港以外，主要是中国）、对吸烟危害的认识不足、对吸烟的积极态度、家庭成员吸烟、参与烟草促销活动以及认为香烟广告有吸引力。观察到的最强关联之一是青少年认为香烟广告有吸引力，调整后的优势比（95%置信区间）为2.68（2.33-3.07）。
年轻人吸烟是一个重要的公共卫生问题。尽管原因是多方面的，但在香港，环境烟草广告是一个重要的风险因素，可通过禁止向年轻人进行一切形式的烟草促销来消除。
