Abstract

Background and objectives: Gay and bisexual men (GBM) are deferred from donating blood in many countries. Perceptions by GBM that blood donor deferral policies are unjustifiably discriminatory, especially due to advances in HIV prevention, could contribute to non-compliance and need to be understood. We explore blood donation interest and history among GBM and attitudes towards donor deferral policies for the first time in New Zealand (NZ).

Materials and methods: Data from a cross-sectional online survey of GBM in NZ were examined. We constructed three groups: (1) never donated blood and not interested; (2) never donated but expressed interest; and (3) previously donated blood. We tested these for association with demographic and behavioural variables, as well as attitudes towards blood donation policy.

Results: A total of 607 GBM were eligible for the study, of whom 32.9% reported having donated blood previously, 44.3% had never donated blood but expressed interest and 22.7% expressed no interest in donating. Among previous donors, a third (8.6% of the total sample) reported non-compliance with the deferral policy. Most participants found the 12-month deferral policy to be too strict (81.8%), unfair (75.4%) and homophobic (68.8%).

Conclusion: We estimate that, for the first time in NZ, almost 10% of the sample did not report compliance with the 12-month deferral policy for men who have sex with men (MSM). Negative attitudes towards the deferral policy were common and could potentially increase the risk to the blood supply if compliance reduces. Further work is needed to inform a deferral policy that is accepted by GBM while maintaining the safety of NZ's blood supply.
