ACE Scores and STI Rates Among Pregnant and Postpartum Persons at a University Hospital [ID 2683476]

INTRODUCTION: Sexually transmitted infections (STIs) have increased across the United States. Universal screening for HIV, hepatitis B, hepatitis C, and syphilis is recommended each pregnancy. Risk-based screening is recommended for chlamydia, gonorrhea, and trichomonas. Adverse childhood experiences (ACEs) quantify exposure to adverse events at age less than 18 years and are associated with risky sexual behavior. Little is known about ACEs and risk of STIs. Risk-based STI screening utilizing ACE score has the potential to improve STI diagnosis and treatment in pregnancy. METHODS: This is a retrospective observational cohort study of pregnant and postpartum persons who underwent ACE scoring from 2015 to 2019. High ACE score was greater than or equal to 4. Using bivariate analyses, we compared percentages of individuals with high versus low ACE scores. We used logistic regression to determine factors associated with cervicitis (gonorrhea, chlamydia, and/or trichomonas positive) and any STI positive (gonorrhea, chlamydia, trichomonas, HIV, syphilis, and/or HSV positive). RESULTS: Adverse childhood experience scores were available for 808 participants. 44% had Medicaid/no insurance. 71% reported White race, 28% Black, and 1.7% other. Mean ACE score was 2.9 (SD 2.5); 37% (n=300) had high ACE score. High ACE was associated with cervicitis (adjusted odds ratio [aOR] 1.762; 95% CI, 0.886–3.503) and any STI positive (aOR 1.187; 95% CI, 0.776–1.815), but not significant. CONCLUSION: Persons with high ACE scores were not more likely to have cervicitis or any STI positivity despite previous studies demonstrating an association to risky sexual behaviors. Our small sample size may contribute to the lack of a statistically significant association. More research is needed to determine if ACE score can be utilized in risk-based STI screening.
