Effect of adverse psychosocial exposures on HIV transmission risk behaviour (inconsistent condom use with male and hijra partners): Additive two-/three-way interactions between violence victimisation, drug use, and frequent alcohol use (N = 22,297).
| Adverse psychosocial exposures and product terms |
Model 1: Two-way product term (V × D) |
Model 2: Two-way product term (V × A) |
Model 3: Two-way product term (D × A) |
Model 4: Two-way product terms alone |
Model 5: All two- and three-way product terms |

Note. 1) The models were adjusted for covariates such as age, education, marital status, sexual identity, forced sex experience during adolescence, HIV risk perception, HIV knowledge, social support and HIV programme exposure. 2) The estimates of the main effects are not shown, and ‘b’ represents the estimated regression coefficient on the product term (use to assess additive interaction).
