Tobacco smoking is an important problem among schoolchildren. The authors studied the patterns of tobacco smoking among schoolchildren in Colombo, Sri Lanka, using a self-administered questionnaire. Multistaged stratified random sampling was used to select 6000 students. Response rate was 90.7% (5446), out of which 53.4% were males. Prevalence rates for males and females, respectively, were as follows: having smoked at least 1 complete cigarette: 27.0% and 13.3%, smoked more than 100 cigarettes: 2.3% and 0.3%, daily smoking: 1.8% and 0.2%. Mean age of starting to smoke was 14.16 years. The tobacco products most used were cigarettes (91.5%) and bidis (3.8%). In univariate analysis, male gender, parental smoking, studying non-science subjects, peer smoking, and participating in sports were significantly associated with smoking of at least 1 complete cigarette (P < .05). In multivariate analysis, the most significant correlates were having close friends (odds ratio = 3.29, confidence interval = 2.47-4.37) or parents who smoked (odds ratio = 1.86, confidence interval = 1.28-2.71). Female smoking has increased from previously reported values. These high-risk groups can be targets for preventive programs.
吸烟在学童中是一个重要问题。作者使用自填式问卷研究了斯里兰卡科伦坡学童的吸烟模式。采用多阶段分层随机抽样选取了6000名学生。回复率为90.7%（5446人），其中53.4%为男性。男性和女性的患病率分别如下：至少吸过1支完整香烟：27.0%和13.3%，吸过100支以上香烟：2.3%和0.3%，每日吸烟：1.8%和0.2%。开始吸烟的平均年龄为14.16岁。最常使用的烟草制品是香烟（91.5%）和比迪烟（3.8%）。在单变量分析中，男性性别、父母吸烟、学习非理科科目、同伴吸烟和参加体育运动与至少吸过1支完整香烟显著相关（P < .05）。在多变量分析中，最显著的相关因素是有亲密朋友（比值比 = 3.29，置信区间 = 2.47 - 4.37）或父母吸烟（比值比 = 1.86，置信区间 = 1.28 - 2.71）。女性吸烟率较之前报告的有所上升。这些高危群体可作为预防项目的目标对象。
