Parents play an important role in the promotion of adolescent sexual health, but little is known about parents' attitudes and beliefs in immigrant families. We examine Hmong American parents' attitudes about adolescent sexual health using survey data from 202 parents of adolescents with attention to parental gender differences. Breaking from traditional views, Hmong American parents most often viewed teen pregnancy as challenging, not beneficial, and advocated the involvement of parents and community leaders in its prevention. The parents also strongly endorsed addressing comprehensive sex education topics for adolescents. Findings encourage proactive efforts to involve Hmong American parents in the promotion of adolescent sexual health, both directly by enhancing parental knowledge and communication with youth and indirectly through parents' support of comprehensive sex education.
