Background: Teenage smoking remains an important problem in Indonesia. This study aimed to determine factors associated with smoking behavior among adolescents using Theory of Planned Behavior.

Subjects and Method: This was an analytic observational study with a cross-sectional design. This study was conducted in Banjarnegara, Central Java, from October to November 2018. A sample of 200 adolescents was selected by random sam­pling. The dependent variable was smoking. The independent variables were intention, atti­tude, subjective norm, perceived behavior control, peer group, family intimacy, and media exposure. The data were measured by questionnaire and analyzed by a multiple logis­tic regression.

Results: Smoking behavior increased with strong intention to smoke (OR= 4.53; 95% CI= 1.45 to 14.1; p= 0.009), strong peer group influence (OR= 3.13; 95% CI= 1.16 to 8.48; p= 0.025), and media exposure (OR= 6.32; 95% CI= 2.29 to 17.4; p<0.001). Smo­king behavior decreased with attitude (OR= 0.26; 95% CI= 0.10 to 0.64; p= 0.004), sub­jective norm (OR= 0.15; 95% CI= 0.58 to 0.40; p<0.001), perceived behavior con­trol (OR= 0.17; 95% CI= 0.06 to 0.46; p= 0.001), and strong family intimacy (OR= 0.31; 95% CI= 0.12 to 0.82; p= 0.019).

Conclusion: Smoking behavior increases with strong intention to smoke, strong peer group influence, and media exposure. Smoking behavior decreases with attitude, sub­jec­tive norm, perceived behavior control, and strong family intimacy.
