Childhood maltreatment and trajectories of cardiometabolic health across the reproductive life span among individuals with a first birth during the Coronary Artery Risk Development in Young Adults Study

OBJECTIVE

Childhood adversity is associated with poor cardiometabolic health in adulthood; little is known about how this relationship evolves through childbearing years for parous individuals. The goal was to estimate differences in cardiometabolic health indicators before, during and after childbearing years by report of childhood maltreatment in the Coronary Artery Risk Development in Young Adults (CARDIA) cohort study.

METHODS

Including 743 individuals nulliparous at baseline (1985-1986) with one or more pregnancies >20 weeks during follow-up (1986-2022), we fit segmented linear regression models to estimate mean differences between individuals reporting or not reporting childhood maltreatment (physical or emotional) in waist circumference, triglycerides, high-density lipoprotein cholesterol, systolic and diastolic blood pressure, fasting glucose, and body mass index (BMI) prior to, during, and following childbearing years using generalized estimating equations, allowing for interaction between maltreatment and time within each segment, and adjusting for total parity, parental education, and race (Black or white, self-reported).

RESULTS

Individuals reporting maltreatment (19%; 141) had a greater waist circumference (post-childbearing: +2.9 cm, 95% CI (0.7, 5.0), higher triglycerides [post-childbearing: +8.1 mg/dL, 95% CI (0.7, 15.6)], and lower HDL cholesterol [post-childbearing: -2.1 mg/dL, 95% CI (-4.7, 0.5)] during all stages compared to those not reporting maltreatment. There were not meaningful differences in blood pressure, fasting glucose, or BMI. Individuals who reported maltreatment did not report faster changes over time.

CONCLUSION

Differences in some aspects of cardiometabolic health between individuals reporting versus not reporting childhood maltreatment were sustained across reproductive life stages, suggesting potentially persistent impacts of childhood adversity.

Understanding the role of childhood nurture, abuse, and stability on gestational diabetes in the Coronary Artery Risk Development in Young Adults study (CARDIA)

BACKGROUND

To estimate associations between facets of the maternal childhood family environment with gestational diabetes (GDM) and to test mediation by pre-pregnancy waist circumference.

METHODS

We used data from CARDIA, a cohort of individuals aged 18-30 years at baseline (1985-86), followed over 30 years (2016). We included participants with one or more pregnancies ≥ 20 weeks after baseline, without pre-pregnancy diabetes. The primary exposure was the Childhood Family Environment Scale (assessed year 15), including the total score and abuse, nurture, and stability subscales as continuous, separate exposures. The outcome was GDM (self-reported at each visit for each pregnancy). We fit log binomial models with generalized estimating equations to calculate risk ratios (RR) and 95% confidence intervals (CI), adjusting for age at delivery, parity, race (Black or White), and parental education. We used regression models with bootstrapped CIs to test mediation and effect modification by excess abdominal adiposity at the last preconception CARDIA visit (waist circumference ≥ 88 cm).

RESULTS

We included 1033 individuals (46% Black) with 1836 pregnancies. 130 pregnancies (7.1%) were complicated by GDM. For each 1 point increase on the abuse subscale (e.g., from "rarely or never" to "some or little of the time") there was a 30% increased risk of GDM (RR: 1.3, 95% CI: 1.0, 1.7). There was evidence of effect modification but not mediation by preconception abdominal adiposity.

CONCLUSIONS

A more adverse childhood family environment was associated with increased risk of GDM, with a stronger association among individuals with preconception waist circumference ≥ 88 cm.

Childhood adversity and the risk of gestational diabetes: A population-based cohort study of nulliparous pregnant women

AIMS

Gestational diabetes mellitus (GDM) is one of the most common pregnancy complications, and though it may be linked to childhood adversity, the effect of different types of adversity remains unclear. Childhood adversity is linked to a younger maternal age, which may hide the overall impact of adversity on GDM risk. We therefore aimed to explore the association between different types of childhood adversity and GDM while accounting for the potential impact of maternal age.

METHODS

We used Danish nation-wide register data, including 208,207 women giving birth for the first time from 2004 to 2018. Five adversity groups were used to examine the effect of childhood adversity on GDM risk: (1) low (referent group), (2) early life material deprivation, (3) persistent deprivation, (4) loss or threat of loss within the family and (5) high adversity.

RESULTS

5375 women were diagnosed with GDM in the study population (2.6% absolute risk). Compared to women who experienced low adversity, the other adversity groups had a higher GDM risk (absolute difference [%]) directly; early material deprivation (0.64% [95% CI 0.44; 0.84]), persistent deprivation (0.63% [0.41; 0.86]), loss or threat of loss (0.73% [0.42; 1.05]) and high adversity (0.80% [0.32; 1.27]). The indirect effect of maternal age attenuated the total effect of childhood adversity on GDM by an absolute difference of 0.25%-0.46%.

CONCLUSIONS

Experiencing childhood adversity to any extent is associated with a higher risk of GDM. Interventions aimed at preventing childhood adversity may have a positive effect in reducing GDM burden and the associated health risks.

Types and timing of trauma exposure across the life course and maternal hypertension

Objective

To estimate associations between types and timing (first occurrence and time since) of trauma exposure and hypertension experienced during pregnancy in a safety-net hospital in Atlanta, Georgia.

Methods

Participants completed a 14-item trauma screener. We linked that information to data from the medical record on hypertension (inclusive of chronic hypertension, gestational hypertension, or preeclampsia). We fit logistic regression models and used the estimates to calculate risk ratios for each trauma type and each critical window (0-9 years, 10-19, and 20+). We fit unadjusted models and adjusted for age, parity, and education.

Results

We included 704 individuals with a delivery within 12 months of screening. The majority (94%, 661) reported at least one traumatic event, most commonly witnessing violence (79.4%). Overall, 18% experienced gestational hypertension, 10.8% chronic hypertension, and 11.9% preeclampsia. Among individuals who reported trauma, 31.5% screened positive for probable posttraumatic stress disorder and 30.9% for probable depression compared to 0 and 2.3% among those without reported trauma. No trauma type (violence, witnessing violence, non-interpersonal, or sexual assault) was associated with increased hypertensive risk, regardless of timing. Similarly, time between trauma and delivery (0-3 years, 3-10 years, 10+ years) was not associated with increased hypertensive risk.

Conclusions

In this sample with a high trauma and hypertension burden, trauma was not associated with elevated risk of hypertension during pregnancy, despite a high burden of PTSD and depressive symptoms among people with trauma exposure. Future research should consider how community-level exposure may modify the impact of trauma on adverse pregnancy outcomes.

Effects of Air Pollution Exposure during Preconception and Pregnancy on Gestational Diabetes Mellitus

This study aimed to investigate the association between air pollution and gestational diabetes mellitus (GDM) in small- and medium-sized cities, identify sensitive periods and major pollutants, and explore the effects of air pollution on different populations. A total of 9820 women who delivered in Handan Maternal and Child Health Hospital in the Hebei Province from February 2018 to July 2020 were included in the study. Logistic regression and principal component logistic regression models were used to assess the effects of air pollution exposure during preconception and pregnancy on GDM risk and the differences in the effects across populations. The results suggested that each 20 μg/m3 increase in PM2.5 and PM10 exposure during preconception and pregnancy significantly increased the risk of GDM, and a 10 μg/m3 increase in NO2 exposure during pregnancy was also associated with the risk of GDM. In a subgroup analysis, pregnant women aged 30-35 years, nulliparous women, and those with less than a bachelor's education were the most sensitive groups. This study provides evidence for an association between air pollution and the prevalence of GDM, with PM2.5, PM10, and NO2 as risk factors for GDM.

Adverse childhood experiences, the risk of pregnancy complications and adverse pregnancy outcomes: a systematic review and meta-analysis

BACKGROUND

Adverse childhood experiences (ACEs) have a profound negative impact on health. However, the strength of the association between ACEs and pregnancy complications and adverse pregnancy outcomes is not well quantified or understood.

OBJECTIVE

To conduct a systematic review and meta-analysis of the association between ACEs and risk of pregnancy complications and adverse pregnancy outcomes.

SEARCH STRATEGY

A comprehensive search was conducted using PubMed, Embase, CINAHL, PsycINFO, ClinicalTrials.gov and Google scholar up to July 2022.

DATA COLLECTION AND ANALYSIS

Two reviewers independently conducted the screening and quality appraisal using a validated tool. Meta-analysis using the quality-effects model on the reported odds ratio (OR) was conducted. Heterogeneity and inconsistency were examined using the I2 statistics.

RESULTS

32 studies from 1508 met a priori inclusion criteria for systematic review, with 21 included in the meta-analysis. Pooled analyses showed that exposure to ACEs increased the risk of pregnancy complications (OR 1.37, 95% CI 1.20 to 1.57) and adverse pregnancy outcomes (OR 1.31, 95% CI 1.17 to 1.47). In sub-group analysis, maternal ACEs were associated with gestational diabetes mellitus (OR 1.39, 95% CI 1.11 to 1.74), antenatal depression (OR 1.59, 95% CI 1.15 to 2.20), low offspring birth weight (OR 1.27, 95% CI 1.02 to 1.47), and preterm delivery (OR 1.41, 95% CI 1.16 to 1.71).

CONCLUSION

The results suggest that exposure to ACEs increases the risk of pregnancy complications and adverse pregnancy outcomes. Preventive strategies, screening and trauma-informed care need to be examined to improve maternal and child health.

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.

Association between poor parent-daughter relationships and the risk of hyperglycemia in pregnancy: a hospital-based prospective cohort study in Japan

BACKGROUND

Adverse child experiences (ACEs), childhood maltreatment and household dysfunction, are risk factors of hyperglycemia in pregnancy (HIP), including diabetes before pregnancy, gestational diabetes (GDM), and overt diabetes in pregnancy, through increased risk of unhealthy behaviors, obesity, and stress response system dysfunction. While ACEs are often difficult to be assessed in hospital settings, parent-daughter relationship, that is, pregnant women's relationship with their parents can be considered as a measurable maker for ACEs that may be associated with HIP. The purpose of this study is to examine the association between poor parent-daughter relationship and HIP.

METHODS

Hospital-based prospective cohort study was conducted in Japan (N = 6,264). Women visiting participating 58 facilities for delivery between April 2019 and March 2020 were included. Parent-daughter relationship was assessed by a questionnaire asking whether participants were satisfied with their relationship with their parents. HIP was diagnosed based on the criteria used in Japan. A multiple logistic regression model was applied to adjust for covariates.

RESULTS

Pregnant women who were not very satisfied and not satisfied at all with the relationship with their parents, and HIP were 343 (5.5%), 74 (1.2%), and 274 (4.4%), respectively. Pregnant women who were not very satisfied with their parent-daughter relationship showed a significant positive association with HIP in the crude model (odds ratio (OR): 1.71, 95% confidence interval (CI): 1.11-2.63). When stratified by psychiatric disease history, we found a significant positive association among those without psychiatric disease history (OR: 1.77, 95% CI: 1.11-2.84), but not among those with psychiatric disease history (OR: 0.61, 95% CI: 0.16-2.28).

CONCLUSIONS

Poor parent-daughter relationship was associated with the risk of HIP among pregnant women without psychiatric disease history, suggesting that this simple question could be used to estimate the risk of HIP when it was challenging to inquire directly about ACEs. Further research is needed to elucidate the mechanism of the association.

Associations of Adverse Childhood Experiences With Pregnancy and Infant Health

INTRODUCTION

Adverse childhood experiences are associated with a host of negative outcomes; however, few have studied cumulative adverse childhood experiences in the context of pregnancy and infant health. This study examines state-level prevalence of adverse childhood experiences and associations with pregnancy- and infant health‒related indicators.

METHODS

The study used 2016-2018 Pregnancy Risk Assessment Monitoring System population-based data from 5 states. Analyses were conducted for individual states and grouped states using similar adverse childhood experience items. Thirteen adverse childhood experience measures were included across 3 domains: abuse, neglect, and household challenges. Adverse childhood experience scores were calculated for the number of adverse childhood experiences experienced (0, 1, 2, ≥3) on the basis of available state measures. Fourteen pregnancy- and infant health‒related indicators were examined, including unwanted pregnancy, adequate prenatal care, experiences during pregnancy (e.g., smoking, abuse, depression), gestational diabetes, hypertensive disorders of pregnancy, birth outcomes (e.g., preterm birth), and breastfeeding. Adjusting for demographics, parity, health insurance status, and educational attainment, prevalence ratios and 95% CIs were calculated to examine the associations between pregnancy- and infant health‒related indicators and adverse childhood experience scores.

RESULTS

Over 50% of respondents reported at least 1 adverse childhood experience and 13%-31% reported ≥3 adverse childhood experiences, depending on the state. Significant associations were identified in all adjusted models between adverse childhood experiences and unwanted pregnancy, smoking, physical abuse, and depression during pregnancy.

CONCLUSIONS

Adverse childhood experiences are associated with risk factors that impact pregnancy and infant health. Preventing and mitigating adverse childhood experiences is an important strategy to improve pregnancy- and infant health‒related indicators.

Adverse childhood experiences and maternal disability: Findings from the North Dakota and South Dakota PRAMS, 2019

RATIONALE

Prior research has found adverse childhood experiences (ACEs) to be a risk factor for disability in adulthood. Moreover, accumulating evidence highlights that both ACEs and disability during pregnancy are a risk factor for both maternal and infant wellbeing. Yet, no previous work has assessed whether ACEs increase the risk of maternal disability.

OBJECTIVE

The current study assesses the link between maternal ACE exposure and disability.

METHODS

Data are from the North Dakota and South Dakota Pregnancy Risk Assessment Monitoring System (PRAMS), 2019 (N = 1775). Logistic regression was used to assess the relationship between accumulating ACEs and maternal disability.

RESULTS

Mothers with exposure to a greater number of ACE-notably, 4 or more ACEs- had elevated rates of several disabilities including difficulty communicating, difficulty remembering, difficulty seeing, and difficulty walking.

CONCLUSIONS

Understanding the long-term health repercussions of ACEs for pregnant women and mothers is important to help inform the design and implementation of health care interventions. This study can be used to better understand the prevalence of disabilities among mothers and corroborate early life experiences as an important risk factor for disability.

Asking About Childhood Adversity in the Prenatal Care Setting: Cross-Sectional Associations with Maternal Health and Mental Health Outcomes

OBJECTIVES

Adverse childhood experiences (ACEs) are associated with poor physical and mental health outcomes in pregnancy, prompting many care agencies to ask about ACEs as part of routine care. However, limited research has been conducted in the clinical setting to demonstrate associations between ACEs and maternal health (i.e., pregnancy complications and birth outcomes) and mental health in pregnancy (i.e., depression, anxiety, and substance use). The aims of the current study were to: (1) examine the prevalence of ACEs reported by patients attending a maternity clinic for medically low-risk patients, and (2) evaluate whether these reports were associated with prenatal health and mental health.

METHODS

Participants included pregnant women (n = 338) receiving prenatal care at a low-risk outpatient medical clinical from June 2017 to December 2018. Total ACE scores, pregnancy complications (e.g., gestational hypertension, preeclampsia), birth outcomes (e.g., Apgar scores, preterm birth), and mental health outcomes (i.e., anxiety, depression, and substance use) were extracted from electronic medical records.

RESULTS

The majority of women (67.8%) reported experiencing no ACEs, 16.0% reported one ACE, 10.1% reported two ACEs, and 6.2% reported three or more ACEs. ACEs were associated with increased odds of prenatal depression, anxiety, and substance use in a dose-response fashion, but not pregnancy health or birth outcomes.

CONCLUSIONS FOR PRACTICE

Prevalence rates of maternal ACEs obtained in the prenatal care setting were low compared to the general population. While ACEs were positively associated with maternal mental health and substance use in pregnancy, they were not associated with pregnancy complications.

Association Between Adverse Childhood Experiences and Adverse Pregnancy Outcomes

OBJECTIVE

To examine the association between adverse childhood experiences and adverse pregnancy outcomes.

METHODS

This cohort study included individuals who enrolled in a perinatal collaborative mental health care program (COMPASS [the Collaborative Care Model for Perinatal Depression Support Services]) between 2017 and 2021. Participants completed psychosocial self-assessments, including an adverse childhood experiences screen. The primary exposure was adverse childhood experiences measured by the ACE (adverse childhood experience) score, which was evaluated as a dichotomized variable, with a high ACE score defined as greater than three. Secondary analyses used the ACE score as a continuous variable. Adverse pregnancy outcomes including gestational diabetes, hypertensive disorders of pregnancy, preterm birth, and small-for-gestational-age (SGA) births were abstracted from the electronic health record. Bivariable and multivariable analyses were performed, including mediation analyses.

RESULTS

Of the 1,274 women with a completed adverse childhood experiences screen, 904 (71%) reported one or more adverse childhood experiences, and 290 (23%) reported a high ACE score (more than three adverse childhood experiences). Adverse childhood experience scores were not associated with gestational diabetes or SGA births. After controlling for potential confounders, individuals with high ACE score had 1.55-fold (95% CI 1.06-2.26) increased odds of having hypertensive disorders of pregnancy and 2.03-fold (95% CI 1.38-2.99) increased odds of preterm birth. Each point increase in ACE score was not associated with a statistically increased odds of hypertensive disorders of pregnancy (adjusted odds ratio [aOR] 1.07, 95% CI 0.99-1.15); however, each additional point on the adverse childhood experiences screen was associated with increased odds of preterm birth (aOR 1.13, 95% CI 1.05-1.22). Mediation analyses demonstrated tobacco use, chronic medical problems, and obesity each partially mediated the observed association between high ACE scores and hypertensive disorders of pregnancy. Having chronic medical comorbidities partially mediated the observed association between high ACE scores and preterm birth.

CONCLUSION

One in four individuals referred to a perinatal mental health program who were pregnant or postpartum had a high ACE score. Having a high ACE score was associated with an increased risk of hypertensive disorders of pregnancy and preterm birth. These results underscore how remote events may reverberate through the life course.

Maternal adverse childhood experiences and pregnancy intentions

PURPOSE

The current study investigates the association between maternal adverse childhood experiences (ACEs) and having an unwanted (i.e., a pregnancy that was undesired) or mistimed pregnancy (i.e., a pregnancy that occurred sooner than wanted).

METHODS

Data are from the 2018 North Dakota and South Dakota Pregnancy Risk Assessment Monitoring System (PRAMS) (N = 1897). Multinomial logistic regression analyses are used to assess the association between levels of ACE exposure and having an unwanted or mistimed pregnancy relative to an intended pregnancy.

RESULTS

Findings demonstrated that women with three ACEs (Relative Risk Ratio [RRR] = 2.157, 95% confidence interval [CI], 1.121-4.151) and four or more ACEs (RRR = 1.836, 95% CI, 1.181-2.854) had approximately twice the relative risk of having an unwanted pregnancy (vs. an intended pregnancy) compared to women with 0 ACEs. There was no association between ACEs and reporting a mistimed pregnancy.

CONCLUSIONS

These findings add to a burgeoning literature detailing how accumulating ACEs can create challenges for family planning by increasing the likelihood of having an unintended pregnancy. Study results suggest the need to devote greater resources to the prevention of ACEs and unintended pregnancies.
