- OBJECTIVES
To investigate the sexual behavioral characteristics and HIV/AIDS knowledge among men who have sex with men (MSM), one of the HIV high risk groups. METHODS: A three month survey among individuals who were able to be contacted was carried out over the entire Republic of Korea, between May and August, 2001. 348 individuals completed a self-administered questionnaire. The data collected included demographic information, sexual behavior and AIDS knowledge. RESULTS: Eighty-seven and ninety-two per cent of the 348 MSM were aged 20-39 years and had never been married, respectively. Fifty-five per cent of participants reported at least one sexual contact with women, and a quarter of the MSM surveyed had engaged in high-risk sexual behavior (more than 6 partners) during the previous year. About twenty per cent of the MSM had anal sex as their favorite way of having sex, and seventy-four per cent did not use condoms regularly due to loss of enjoyment, and were more likely to be engaged in risky behaviors. Only ten per cent had a regular HIV test history, and most had obtained knowledge or information on HIV/AIDS through the mass media. CONCLUSIONS: A large proportion of the MSM in Korea still remain at an elevated risk for contracting HIV infection. Change in high-risk sexual behaviors will prevent the spread of HIV infection among the MSM population, which requires public health education for preventive interventions, and should be culturally and socially specific in order to be effective.

- OBJECTIVE
To estimate the status of HIV infection and AIDS incidence using a back-calculation model in Korea. METHODS: Back-calculation is a method for estimating the past infection rate using AIDS incidence data. The method has been useful for obtaining short-term projections of AIDS incidence and estimating previous HIV prevalence. If the density of the incubation periods is known, together with the AIDS incidence, we can estimate historical HIV infections and forecast AIDS incidence in any time period up to time t. In this paper, we estimated the number of HIV infections and AIDS incidence according to the distribution of various incubation periods RESULTS: The cumulative numbers of HIV infection from 1991 to 1996 were 708~1,426 in Weibull distribution and 918~1,980 in Gamma distribution. The projected AIDS incidence in 1997 was 16~25 in Weibull distribution and 13~26 in Gamma distribution. CONCLUSIONS: The estimated cumulative HIV infections from 1991 to 1996 were 1.4~4.0 times more than notified cumulative HIV infections. Additionally, the projected AIDS incidence in 1997 was less than the notified AIDS cases. The reason for this underestimation derives from the very low level of HIV prevalence in Korea. Further research is required for the distribution of the incubation period of HIV infection in Korea, particularly for the effects of combination treatments.

- OBJECTIVES
Despite the importance of human immunodefi-ciency virus(HIV) transmission through heterosexual contact, the features of heterosexual transmission has not been well studied in Korea. So we conducted a cross sectional study to determine the transmission rates in married couples and assess risk factors for male to female heterosexual transmission of HIV. METHODS: 169 HIV-infected males and their female sex partners were recruited from 1985 to June 1998. We examined female sex partners HIV infection status and interviewed male index partners and their female sex partners about demographic characteristics and sexual practices. We analysed heterosexual transmission rate by epidemiologic characteristics, disease status and sexual practices. And we assessed risk factors for HIV infection by univariate and multivariate analysis. RESULTS: 30 female sex partners were infected at enrollment, yielding an transmission rate of 17.8%. Among couples who had used condoms consistently, none of the female sex partners was infected with HIV. In univariate analysis the significant risk factors were full blown AIDS status (OR=4.1, 95% CI: 1.49-11.43) and low CD4 T cell count of index partners at enrollment (OR=7.8, 95% CI: 2.19-27.80). In multivariate analysis HIV-1 RNA levels was significant risk factor when adjusted by CD4 T cell counts and mean sexual contacts per month (OR=19.2, 95% CI: 1.03-357.59) CONCLUSION: The risk of male to female heterosexual transmission increased with advanced stages of HIV infection in the index male partners.
