Knowledge, attitudes and behaviour towards HIV infection among family planning clinic attendees: changes between 1991...

To detect changes in knowledge, attitudes and behaviour towards HIV infection amongst Family Planning Clinic attendees in Christchurch, New Zealand, between 1991 and 1997.

A voluntary, anonymous, self-administered questionnaire was applied to consecutive subjects attending the Montreal Centre of the Family Planning Association in Christchurch, in 1991 and repeated in 1997. Results were compared to assess changes in demographic features, knowledge, attitudes and behaviour pertaining to HIV infection between these times.

A 99% response rate was obtained in 1991 and 98% in 1997. Two hundred people in 1991 and 353 people in 1997 responded. These predominantly female heterosexual groups were demographically similar. Levels of knowledge pertaining to HIV infection were high and did not change significantly between 1991 and 1997, except for a rise in the proportion who felt donating blood was a high risk behaviour from 12.0% to 25.7% (p<0.001). HIV testing and discussion about HIV testing amongst couples was more common in 1997. However, the use of recreational intravenous drugs rose from 5.0% to 10.6% (p=0.025), condom use with every new partner fell from 65.1% to 42.1% (p=0.001) and the perceived risk of acquiring HIV in New Zealand and several Western Hemisphere countries fell, with 40.0% perceiving the South Island as a high-risk place in 1991 to 24.1% in 1997(p<0.001). This was paralleled by an apparent rise in known HIV testing.

This predominantly heterosexual population appears to have maintained good levels of knowledge about HIV infection. However, this does not seem to be being translated into safer behaviour. This study detects alarming changes in behaviour in the face of adequate knowledge levels and increased testing for HIV which may provide pathways for entry of HIV into, and transmission within, the heterosexual population of New Zealand. Several aims of the New Zealand Strategy on HIV/AIDS 1990 need to be revisited in light of the evidence and resources directed appropriately.
