Racial/Ethnic Disparities in Female Sexual Health from Adolescence to Young Adulthood: How Adolescent Characteristics Matter?

Study Objective To describe sexual initiation patterns in female adolescents and examine their association with adolescent characteristics and racial disparities in adverse sexual health across adolescence into early adulthood. Design A prospective, longitudinal, observational study from adolescence to adulthood. Setting Nationally representative, the National Longitudinal Study of Adolescent to Adult Health data, in the range of 24-32 years old at final assessment. Participants Data from 43,577 US women from 1994 to 2008. Interventions and Main Outcome Measures Adolescent sex-related characteristics at the individual-, family-, and school peer-level were assessed, and multiple sex partners, sexually transmitted infections (STIs)/HIV, and intimate partner violence (IPV) were longitudinally tracked. The sexual initiation pattern and its longitudinal association with sexual health were analyzed using latent class analysis and mixed effects Poisson regression models. Results Of the 43,577 subjects, the sexual initiation patterns were determined as normative (n = 28,712, 65.9%), late (n = 10,799, 24.8%), and early but unempowered (n = 4,066, 9.3%). The highest rate of the early-unempowered group was shown in Hispanic individuals (1,054/7,307 = 14.4%); they were more likely to be depressed, unsatisfied with their bodies, receiving welfare, and have less educated/permissive parents to their sexual initiation than others. The late group had a higher body mass index and greater satisfaction with their bodies. The highest number of STIs/HIV and IPV victimization was shown in non-Hispanic Black (NHB) and Hispanic individuals, respectively. However, NHB females’ higher number of STIs/HIV was shown in the late/normative groups, not in the early-unempowered group. Among Hispanic females, adolescent sexual initiation patterns were not directly associated with their frequent IPV victimization. Conclusion NHB females' higher STI/HIV in late/normative groups and Hispanic females’ frequent IPV victimization regardless of their sexual initiation patterns might indicate that racial/ethnic disparities in female sexual health was not directly determined by adolescent risk behaviors.
