Prevalence and factors associated with current smoking among high school adolescents in Karachi, Pakistan.
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.
