* p < .05; ** p < .01; *** p < .001; ns = not significant; AOR = Adjusted Odds Ratio; 95%CI = 95% Confidence Interval; Ref = Reference Category. Note All analyses limited to those who have had sex in last 12 months. Backward conditional logistic regression was utilised with non-significant factors being removed from the final model. Frequency of alcohol use was an independent variable in all analyses but was not significantly related to any dependents and therefore is not shown above. |
