Statistical significance indicated in bold (p<0.05). Only variables from the univariate analysis with p≥0.2 were included in the multivariate analysis.
The subcategories per risk group are mutually exclusive.
*Information on sexual preference was not given for 82 men; these men are classified as heterosexual.
†Missing; report forms were not complete for all variables; ‘missing’ was included as a category in univariate and multivariate analyses; OR’s are not reported for this group except in the case where there was a significant association (number of partners).
‡Nine MSM were not tested because they were already known to be HIV positive.
AOR, adjusted OR from multivariate logistic regression; MSM, men who have sex with men; ns, not significant; STI, sexually transmitted infection.
