Racial-ethnic disparities in adolescent sexual behaviours: the cross-sectional Youth Risk Behavior Survey, 2009–19.

BACKGROUND

There are notable disparities by race/ethnicity in the sexual health of US adolescents and young adults. Our objective was to examine change over time in racial-ethnic disparities in sexual behaviours among US high school students.

METHODS

Data were analysed from six biennial cycles of the national Youth Risk Behavior Survey (2009-19), conducted among cross-sectional, nationally representative samples of 9th-12th grade students. Data were collected via self-administered questionnaires. Multivariable logistic regression models tested for linear trends by race/ethnicity (White, Black, Hispanic) and differences in these trends in: ever had sex, current sexual activity, having four or more lifetime sexual partners, and condomless sex. Prevalence ratios and risk differences by race/ethnicity for each cycle were used to calculate average percent change in the estimates to determine if health disparities changed over time.

RESULTS

During 2009-19, prevalence estimates for ever had sex, current sexual activity, and having four or more lifetime sexual partners decreased overall and across all racial-ethnic groups. For condomless sex, prevalence estimates increased over time overall (38.9-45.7%) and for Black (37.6-51.8%) and White (36.7-44.2%) students, but not Hispanic (45.1-43.8%) students. Significant differences in trends by race/ethnicity were observed for all variables. Data suggest that racial-ethnic health disparities for sexual behaviours decreased over time, except for condomless sex.

CONCLUSIONS

Although racial-ethnic gaps in sexual behaviours may be shrinking for many behaviours, work is still needed to achieve health equity in risks associated with HIV/AIDS, sexually transmitted infections, and pregnancy.
