Background: Previous studies reported that critical factors that contribute to in­crea­sing the risk of smoking among adolescents include peer pressure through siblings’ and/or friends’ smoking, tobacco industry advertising and easy access to tobacco pro­ducts and their low prices. This study aimed to examine factors affecting smoking be­havior among high school students using theory of planned behavior.

Subjects and Method: A cross sectional study was conducted in Bantul, Central Java, from April to May 2019. A sample of 200 male adolescents was selected for this stu­d­y by stratified random sampling. The dependent variable was smoking behavior. The independent variables were knowledge, family role, peer role, cigarette price, mo­ney pocket, and attitude. The data were collected by questionnaire and analyzed by a mul­­tilevel multiple logistic regression run on Stata 13.

Results: Smoking behavior among male adolescents decreased with good knowledge (b= -3.30; 95% CI= -0.35 to -0.09; p= 0.001), strong family role (b= -3.11; 95% CI= -1.15 to -0.26; p= 0.002), low peer role (b= -3.92; 95% CI= -1.10 to -0.36; p<0.001), high price of cigarette (b= -2.81; 95% CI= -1.10 to -0.19; p= 0.005), low money pocket (b= -3.79; 95% CI= -5.75 to -0.01; p<0.001), and attitude (b= -3.37; 95% CI= -0.15 to -0.05; p= 0.001).

Conclusion: Smoking behavior among male adolescents decreases with good know­ledge, strong family role, low peer role, high price of cigarette, low money pocket, and attitude.
