Abstract
From October 1985 to November 1987, a sample of 294 Colombian homosexual men volunteered to answer a questionnaire on sexual practices and consented to HIV-1 testing. Testing for HIV-1 was performed using an ELISA and those positive were confirmed with envelope- and core-specific ELISAs. Statistical methods for data analysis included Mantel-Haenszel methods on contingency tables. The overall seropositivity rate was 21.1%. Subjects who reported a receptive role (either as predominantly receptive or as mixed receptive-insertive intercourse) had a seropositivity rate of 23.7%, which was significantly higher than the 10.3% found in those reporting predominantly insertive intercourse (RR = 2.30, 95% C.I. = 1.16-4.57). For subjects reporting receptive intercourse, sexual contact with foreign visitors was a significant risk factor for HIV-1 infection (RR = 1.84, 95% C.I. = 1.13-3.00). Factors of borderline significance included having had more than ten homosexual partners in the preceding year (RR = 1.53) and a history of international travel (RR = 1.43). These associations did not hold for those reporting predominantly insertive intercourse. The data indicate the need to monitor the spread of HIV-1 at the international level and provide information on subgroups of high transmission rates.
