Table 4.
Factors associated with ever smoking and ever drinking among the adolescents through logistic regression analysis (forward stepwise).
| Variable | Ever Smoking | Ever Drinking | ||||||
|---|---|---|---|---|---|---|---|---|
| OR | 95% CI | p-Value | OR | 95% CI | p-Value | |||
| Peer offer of tobacco or alcohol | ||||||||
| Yes | 37.54 | 7.81–180.46 | <0.001 | *** | 6.19 | 1.49–25.78 | 0.012 | * |

| Peer drinking | ||||||||
| Yes | 8.41 | 1.55–45.54 | 0.013 | * | ||||
| No | 1 | |||||||
| Peer smoking | ||||||||

*** p < 0.001, * p < 0.05. OR = odds ratio; 95% CI = 95% confidence interval. Note: Logistic regression and the forward stepwise selection method were used with the adolescents’ gender and residential area as control variables. The variables in which significant differences were observed in bivariate analysis were considered as the independent variables.
