Infrequent condom use with casual partners among New Zealand gay and bisexual men.

AIMS: To identify predictors of non-condom use among gay and bisexual men (GBM) in New Zealand with casual male partners.

METHODS

We analysed anonymous self-completed data from GBM who participated in the communitybased Gay Auckland Periodic Sex Survey (GAPSS) and Internet-based Gay Online Sex Survey (GOSS), undertaken in 2014. Infrequent condom use was defined as not using condoms "always" or "almost always" during anal intercourse in the prior six months.

RESULTS

Of the 1,912 GBM reporting anal intercourse with a casual partner, 27.2% reported infrequent condom use. Being recruited from Internet dating sites, Pacific ethnicity, having over 20 recent male partners, infrequent condom use with a current regular partner, or being HIV-positive were independently predictive of infrequent condom use. Conversely, being older, having a tertiary degree, using a condom at first anal intercourse, being exclusively receptive with a casual partner/s, and seeing condoms promoted through multiple channels predicted frequent condom use. Attitudes to condoms and safe sex were strongly predictive of actual condom use.

CONCLUSIONS

Social marketing should target the modifiable predictors of condom use, such as attitudes to safe sex. Interventions also need to engage successfully with GBM reporting non-modifiable traits such as HIV-positive GBM.
