Associations between adverse childhood experiences and obstetrical outcomes in a predominantly Black-identifying and low-income pregnant population.

BACKGROUND: Recent literature indicates that adverse childhood experiences have been associated with poor obstetrical outcomes, including pregnancy loss, preterm birth, and low birthweight. Several studies have been conducted in primarily self-identified White individuals who report middle to high income levels. Less is known about the impact of adverse childhood experiences on obstetrical outcomes in minority-identifying and low-income populations, who are known to experience a greater number of adverse childhood experiences and are at higher risk of maternal morbidity. OBJECTIVE: This study aimed to examine associations between adverse childhood experiences and a broad range of obstetrical outcomes among predominantly Black-identifying pregnant persons who have low income and live in an urban area. STUDY DESIGN: This is a single-center retrospective cohort study of pregnant persons referred to a mental healthcare manager because of elevated psychosocial risks identified by screening tools or provider concerns during the study period from April 2018 to May 2021. Pregnant persons aged <18 years and those who did not speak English were excluded. Patients completed validated mental and behavioral health screening tools including the Adverse Childhood Experiences Questionnaire. Medical charts were reviewed for obstetrical outcomes, including preterm birth, low birthweight, hypertensive disorders of pregnancy, gestational diabetes mellitus, chorioamnionitis, sexually transmitted infection, maternal group B streptococcus carrier status, type of delivery, and attendance of a postpartum visit. Associations between high (≥4) and very high (≥6) of 10 adverse childhood experience score and obstetrical outcomes were analyzed using bivariate analysis and multivariate logistic regression, adjusting for confounding factors (significant at P<.05 in bivariate analysis). RESULTS: Our cohort included 192 pregnant persons, of whom 176 (91.7%) self-identified as Black or African American and 181 (94.8%) had public insurance (used as a proxy for low income). Adverse childhood experience score ≥4 was reported by 91 (47.4%) individuals and score ≥6 by 50 (26%). On univariate analysis, adverse childhood experience score ≥4 was associated with preterm birth (odds ratio, 2.17; 95% confidence interval, 1.02-4.61). Adverse childhood experience score ≥6 was associated with hypertensive disorders of pregnancy (odds ratio, 2.09; 95% confidence interval, 1.05-4.15) and preterm birth (odds ratio, 2.29; 95% confidence interval, 1.05-4.96). After accounting for chronic hypertension, associations between adverse childhood experience score and obstetrical outcomes were no longer significant. CONCLUSION: Approximately half of the pregnant persons referred to a mental healthcare manager had a high adverse childhood experience score, underscoring the high burden of childhood trauma on populations facing long-standing systemic racism and barriers to healthcare access. High and very high adverse childhood experience score may be associated with chronic health conditions that predate pregnancy and can alter obstetrical outcomes. Obstetrical care providers have a unique opportunity to mitigate risk of associated poor health outcomes during preconception and prenatal care by screening for adverse childhood experiences.

Associations Between Adverse Childhood Experiences and Prenatal Mental Health and Substance Use Among Urban, Low-Income Women.

This study examined associations between Adverse Childhood Experiences (ACEs) and perinatal mental health and substance use among 98 low-income women (mean age 25.4 years; 93% Black/African American) referred to a mental health care manager in an urban women's clinic. Self-report and retrospective chart review data were utilized. Chi-squared and Fisher's Exact tests were performed to assess bivariate relationships between ACEs and mental health and substance use outcomes. Multivariate logistic regressions were used to examine the impact of ACEs on mental health and substance use, adjusting for marital status, education, and age. Findings indicate high levels of childhood adversity, specifically childhood abuse, are associated with negative perinatal mental health and substance use outcomes, including suicidal thoughts, anxiety, mood dysregulation, and tobacco and marijuana use. Inquiring about ACEs during prenatal care and/or in community health clinics may help identify patients' overall risk and provide opportunities for intervention for mothers and their infants.
