Abstract
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.
