Sexism and sexual risk behavior in adolescents: Gender differences.

: This study examines whether there are differences in the maintenance of ambivalent sexist beliefs on the basis of gender and sexual experience in adolescents. The study also investigates whether the sexist beliefs themselves are linked to sexual risk behaviors. : A representative sample of 2,703 Spanish adolescents was carried out in public and private secondary schools, with an age range of 14 to 20 years old ( = 15.89; = 1.29). : Males maintain more hostile, benevolent and ambivalent sexist beliefs compared to females. Sexual experience (both coital and non-coital) is linked to a greater degree of hostile and benevolent sexist beliefs, but only within the male group. In males, greater benevolent sexism is linked to vaginal sex initiation at an earlier age, while greater hostile sexism is linked to a lower proportion of condom use. In females, greater hostile sexism is linked to a greater number of sex partners. : It is necessary to include specific actions on sexist beliefs in programs for the prevention of sexually transmitted infections and HIV.
