Youth Research

Supporting contraceptive access and equity in adolescents and young adults

Young people across the United States face critical barriers to contraceptive care. We conduct research among youth populations to better understand these barriers, as well as youth preferences, beliefs, and awareness of different methods. With our Youth Advisory Board, we develop, test, and disseminate effective interventions to increase youth contraceptive access and equity.

Our research supports young people a number of ways:

  • We consult and collaborate with youth and youth advocates to improve our research through our Youth and Community Advisory Boards.
  • Our research informs clinical practice and policy and supports increased access to quality contraceptive care for young people, especially in restrictive environments.
  • We test educational interventions that improve youth access to sexual health information and support greater reproductive autonomy for young people.
  • We directly counteract scientific misinformation on contraception with youth-friendly visual resources that describe available methods and how to access them.
  • As young people face a worsening mental health crisis, we investigate the relationship between sexual and reproductive health and mental health.
  • Our work supporting community college students’ access to quality, comprehensive sexual and reproductive health care services has been recognized by the Institute for Women’s Policy Research, and we are grantees of their Connect for Success program.

REACH Youth: Reproductive Equity and Access in College Health

Our ongoing study among community college students in Texas and California tests an intervention to increase contraceptive access and equity. The intervention seeks to increase health and gender equity for these young people in a crucial stage in their life, as they move from adolescence to young adulthood.

Young people don’t know about their emergency contraception options, but that can change

Our 2023 study, published in the Journal of Adolescent Health, found that timely educational interventions can improve young people’s knowledge of their emergency contraceptive (EC) options. Researchers held a low-cost, 10-minute education session using youth-friendly visuals explaining the different EC options. The young people in the study showed significant increases in knowledge of different EC methods, and of critically important facts like how time sensitive each method is, which methods are available at the clinic or directly at the pharmacy, and the relative effectiveness of each option (Fig. 1)
