Q1. What have the authors contributed in "A tale of two countries: rethinking sexual risk for hiv among young people in south africa and the united states" ?
Purpose—To compare the sexual behaviors of young people in South Africa ( SA ) and the United States ( US ) with the aim of better understanding the potential role of sexual behavior in HIV transmission in two countries with strikingly different HIV epidemics. Young women and men in the US reported an earlier age of first sex than those in SA ( mean age of coital debut for females: US ( 16. 5 ), SA ( 17. 4 ) ; for males: US ( 16. 4 ), SA ( 16. 7 ) ). Conclusions—Young people in the US report riskier sexual behaviors than young people in SA, despite the much higher prevalence of HIV infection in South Africa.
