Table 4.
Factors related to dual smoking based on multivariate logistic regression analysis
| Factors | Dual smoking | Adj. OR | P value |
|---|---|---|---|
| Female sex | 39.5% | 1 | |
| Male sex | 60.5% | 3.8 | 0.001 |
| Age | 1.06 | 0.00 | |
| Water pipe smoking allowed at home | 60.7% | 1 | |
| Water pipe smoking not allowed at home | 11.7% | 0.318 | 0.026 |
| No specific rule in this regard | 11.3% | 0.06 | 0.01 |
Based on Table 4, male sex significantly increased the odds of dual smoking. Older age also had a significant association with the odds of dual smoking (OR: 1.06). Prohibition of water pipe smoking at home had a protective effect on dual smoking.
