Smoking is the second cause of death in the world. It currently accounts for one out of ten deaths in adults worldwide (5 million per year). If current patterns persist, smoking will cause 10 million deaths a year by 2020 according to the World Health Organization. A prevalence study on smoking habits was conducted in 2002 among 459 students from eight public high schools in Santa Maria, Rio Grande do Sul State, Brazil. This study aimed to measure smoking prevalence and related factors by multivariate logistic regression. The overall smoking prevalence rate in the sample was 18% (95%CI: 14.6-21.7), and the students had begun smoking at a mean age of 14 years. Students from public high schools had begun smoking early, influenced by friends who smoked (OR = 4.37; p = 0.000), family income (OR = 2.04; p = 0.013), and age (OR = 1.86; p = 0.031). It is thus crucial to adopt measures to prevent adolescents' access to smoking.
吸烟是全球第二大致死原因。目前，它导致全球成年人中每十例死亡中就有一例（每年500万例）。如果当前模式持续下去，据世界卫生组织称，到2020年吸烟将导致每年1000万人死亡。2002年，在巴西南里奥格兰德州圣玛丽亚市八所公立高中的459名学生中开展了一项吸烟习惯流行率研究。本研究旨在通过多变量逻辑回归来衡量吸烟流行率及相关因素。样本中的总体吸烟流行率为18%（95%置信区间：14.6 - 21.7），学生开始吸烟的平均年龄为14岁。公立高中的学生受吸烟朋友的影响（比值比 = 4.37；p = 0.000）、家庭收入（比值比 = 2.04；p = 0.013）和年龄（比值比 = 1.86；p = 0.031），吸烟较早。因此，采取措施防止青少年接触吸烟至关重要。
