For more than two decades, the United States has reported significant declines in teen pregnancy, teen birth, and teen abortion rates, as much research and programmatic attention has been directed toward addressing these issues. Yet, rates of unplanned pregnancies have remained largely unchanged, and the U.S. teen pregnancy rates remain the highest in the industrialized world. Moreover, the issue of pregnancy risk among sexual minority (nonheterosexual) adolescents had been largely ignored in pregnancy prevention research. 

Lisa Lindley, an associate professor in George Mason’s College of Health and Human Services’s Department of Global and Community Health, conducts research focused on sexual health promotion and the prevention of HIV/STIs and unintended pregnancies among underserved populations. Her most recent paper, “Sexual Orientation and Risk of Pregnancy Among New York City High-School Students,” examined the association between sexual orientation and pregnancy risk among students who had engaged in vaginal intercourse and found that self-identified LGB (lesbian, gay, or bisexual) students were significantly more likely to get pregnant or to impregnate a partner.

Things To Know

  • In research, at least three dimensions of sexual orientation can be measured: 1) sexual attraction; 2) sexual behavior; and 3) sexual identity.
  • Sexual attraction refers to the feelings of romantic or sexual interest toward another person. Researchers measure the sex(es) or gender(s) to which individuals are attracted.
  • Sexual behavior refers to different activities (oral, vaginal, anal intercourse, etc.) that someone engages in with partners of the same sex, opposite sex, or both sexes. This is becoming a less accurate measure as more people are having sexual and romantic relationships with transgender individuals.
  • Sexual identity is how a person labels their sexual orientation (gay, lesbian, bisexual, or heterosexual). However, other identities are frequently used to label one’s sexual orientation (asexual, pansexual, and queer).
  • These three dimensions do not necessarily align in people. For example, a person may be attracted to someone of the same sex but not act on those feelings (only has sexual relationships with the opposite sex) and identifies as heterosexual, or someone may identify as bisexual and only have same sex partners.
  • Most people are concordant across the three dimensions; they are attracted to the opposite sex, only have opposite sex partners, and identify as heterosexual. However, many people, especially females, are discordant across the three dimensions.
  • Asking questions about the different dimensions of sexual orientation allows researchers to more comprehensively examine the role of sexual orientation as a predictor of health, social, and economic outcomes.
