Patterns of serologic testing in HIV-1 seronegative men

This study defined and examined two groups of homosexually active men seeking an HIV-antibody test in a sample of 903 HIV-seronegative men who tested regularly. The 'event-related' (ER) group tested when circumstances motivated them. The 'time-related' (TR) group sought testing at regular time intervals not related to any particular event. Univariate and multivariate techniques were used to determine whether variables such as age, sexual identity, sexual relationships and practices distinguished between these two groups and were predictive of test frequency in the TR group. The results revealed the ER group was more likely to have a condom break in the last six months than the TR group, and the TR group was more likely to have had in excess of five HIV tests and to have been tested within the last six months. A discriminant function test did not reach statistical significance. Predictive of test frequency in the TR were current sexual relationships, safety (with respect to HIV transmission) of sexual practices with men, using HIV-testing as a preventative strategy, age and knowledge of safe sexual practice (R(2)=10.5%). These findings suggest that there is over-use of the test both by those whose practices are adequately minimising their risk, and some who may use the test as a substitute for safe sexual practice.
