Our objective was to estimate the prevalence and evaluate factors associated with smoking among high school adolescents in Karachi, Pakistan. A school-based, cross-sectional survey was conducted in three towns in Karachi, namely, Gadap Town, Bin-Qasim Town and Malir Town, from January through May 2003. Two-stage cluster sampling stratified by school type was employed to select schools and students. We recruited and interviewed 772 male students regarding socio-demographic factors, smoking history of students, their families/friends, number of siblings, and place of residence. The prevalence of smoking (30 days) among adolescents was 13.7%. Final multiple logistic regression analysis showed that after adjusting for age, ethnicity, and place of residence, being a student at a government school (OR=1.6; 95% Cl: 1.0-2.7), parental smoking (OR = 1.7; 95% Cl: 1.1-2.8), uncle smoking (OR = 1.7; 95% Cl: 1.2-2.8), peer smoking (OR = 6.2; 95% Cl: 3.9-9.9), and spending leisure time outside home (OR = 3.9; 95% Cl 1.2-13.2) were significantly associated with adolescent smoking.
我们的目标是估计巴基斯坦卡拉奇市高中青少年的吸烟率，并评估与吸烟相关的因素。2003年1月至5月，在卡拉奇的三个镇，即加达普镇、本·卡西姆镇和马里尔镇开展了一项基于学校的横断面调查。采用按学校类型分层的两阶段整群抽样方法来选择学校和学生。我们招募并访谈了772名男学生，了解他们的社会人口学因素、学生及其家人/朋友的吸烟史、兄弟姐妹数量和居住地点。青少年（30天内）的吸烟率为13.7%。最终的多因素logistic回归分析显示，在调整年龄、种族和居住地点后，在政府学校就读（比值比=1.6；95%置信区间：1.0 - 2.7）、父母吸烟（比值比 = 1.7；95%置信区间：1.1 - 2.8）、叔叔吸烟（比值比 = 1.7；95%置信区间：1.2 - 2.8）、同伴吸烟（比值比 = 6.2；95%置信区间：3.9 - 9.9）以及在家外度过休闲时间（比值比 = 3.9；95%置信区间1.2 - 13.2）与青少年吸烟显著相关。
