Prevalence of Early Sexual Debut among Young Adolescents in Ten States of the United States

Sexual debut among young adolescents is under-investigated. In this quantitative descriptive study, we examined the 2019 Middle School Youth Risk Behavior Survey (YRBS) data of 66,366 young adolescents aged 10–14 from 10 states to determine the prevalence of early sexual debut among young adolescents. Data analyses used state-level sampling weights as described in the CDC’s 2019 Middle School YRBS user guide. Nearly 8% of the sample reported having had sexual intercourse. Of those who reported age of first sex, 4% had their first sexual intercourse before 13 years of age. Compared to Whites, young Black/African American (13.2% vs. 5.1%, OR = 4.51, 95% CI: 2.78–7.31) and Hispanic adolescents (8.3 % vs. 5.1 %, OR = 1.44, 95% CI = 1.13–1.84) were more likely to report having early sexual intercourse. Males were more likely to report having multiple sexual partners than females (48.1% vs. 36.5%, OR = 1.68, 95% CI = 1.22–2.29) and were more likely to report using condoms during their last sexual intercourse compared to their female counterparts (59.7% vs. 50.8%, OR = 1.43, 95% CI = 1.06–1.94). This study suggests the need for more research on young adolescents’ sexual behaviors and for the development of sexual health interventions that target young adolescents.
