ABSTRACT
To assess sexual behaviour and awareness about sexually transmitted infections [STIs] among young male adults in Lebanon, and to explore determinants associated with increasing levels of sexual risk, a cross-sectional survey of 730 conscripts was conducted. About 50% reported any lifetime heterosexual experience. Non-mutually exclusive sex predominated, and only half of the respondents reported consistent condom use during insertive vaginal sex. Higher sexual risk-taking was associated with urban residence, higher education, lower family crowding and younger age at first sexual experience. A national strategy with epidemiological and behavioural surveillance and educational programmes must be initiated before sexual risk-taking and incidence of STIs become a major public health issue
