Abstract:

Purpose

Early life adversity (ELA) is associated with sexual risk, but ELA dimensions—and potential mechanisms—have been less examined. We evaluated associations between threat and deprivation—two key ELA dimensions—and sexual behaviors in adolescents. Secondary analyses investigated age at menarche as a mechanism linking ELA with sexual outcomes in girls. We predicted associations between threat and sexual behaviors, with younger age at menarche as a pathway.

Methods

Data were from the National Comorbidity Survey, Adolescent Supplement. Adolescents and caregivers reported on youths' ELA experiences, which were categorized as threat- or deprivation-related. Adolescents reported if they engaged in sex (N = 9,937) and on specific sexual risk indicators, including age at first sex, number of past-year sexual partners, and condom use consistency (“always” vs. “not always” used). Girls reported age at menarche.

Results

Threat (odds ratio [OR] = 1.76 [95% confidence interval [CI], 1.62–1.92]) and deprivation (OR = 1.51 [95% CI, 1.24–1.83]) were each linked with engagement in sex, ps<.05. Threat-related experiences were associated with multiple sexual risk markers, even when accounting for deprivation: earlier age at first sex (b = −0.20 [95% CI, −0.27 to 0.13]), greater number of partners (b = 0.17 [95% CI, 0.10–0.25]), and inconsistent condom use (OR = 0.72 [95% CI, 0.64–0.80]), ps <.001. Deprivation was not associated with sexual risk when adjusting for threat. We observed no significant indirect effects through age at menarche.

Discussion

Although threat and deprivation were related to engagement in sexual activity, threat-related experiences were uniquely associated with sexual risk. Screening for threat-related ELA may identify adolescents at-risk for poor sexual health.
