BACKGROUND: The COVID-19 pandemic affected adolescents' sexual and reproductive health (SRH) behaviors and access to services. METHODS: We analyzed data from the 2021 Adolescent Behaviors and Experiences Survey (n=7,705) on sexual activity, condom and contraceptive use, and sexually transmitted infection (STI) testing. We tested differences in SRH outcomes by demographics, racism experience, and English proficiency. RESULTS: Current sexual activity was higher among students reporting ever experiencing racism at school and self-rating how well they can speak English as "not well." Condom use differed by sex, sexual identity, and sex of sexual contacts. Demographic differences in contraceptive use were also identified. Sexually active females (vs. males) and males with same-sex or both-sex contacts (vs. opposite-sex) had higher STI testing. CONCLUSION: Differences by students' demographic characteristics and experiences during the pandemic highlight needs to enhance accessibility and quality of adolescent SRH services and education in schools, clinics, and communities.
