Prospective associations of prenatal stress with child behavior: Moderation by the early childhood caregiving environment.

Fetal exposure to prenatal stress can increase risk for psychopathology but postnatal caregiving may offset risk. This study tests whether maternal sensitivity and the home environment during early childhood modify associations of prenatal stress with offspring behavior in a sample of 127 mother-child pairs (n = 127). Mothers reported on perceived stress during pregnancy. Maternal sensitivity was rated by coders during a parent-child free play task when children were 4 years old. One year later, mothers reported on the home environment, child internalizing and externalizing behaviors, and children completed an assessment of inhibitory control. As hypothesized, the early childhood caregiving environment modified associations of prenatal stress with child behavior. Specifically, prenatal stress was associated with more internalizing behaviors at lower levels of maternal sensitivity and in home environments that were lower in emotional support and cognitive stimulation, but not at mean or higher levels. Furthermore, prenatal stress was associated with lower inhibitory control only at lower levels of maternal sensitivity, but not at higher levels. Maternal sensitivity and an emotionally supportive and cognitively stimulating home environment in early childhood may be important factors that mitigate risk for mental health problems among children exposed to prenatal stress.

Prenatal stress and hair cortisol in a sample of Latina women.

BACKGROUND: Stress during pregnancy adversely impacts maternal and infant health. Dysregulation of the hypothalamic pituitary axis is a mediator of the relationship between stress and health. Evidence supporting an association between prenatal chronic stress and cortisol is limited, and the majority of research published has been conducted amongst White participants, who experience less chronic stress than people of color. AIM: This study investigated associations between various measures of prenatal stress and hair cortisol concentrations which is a biomarker of the integrated stress response in a sample of Latina participants during the third trimester of pregnancy. METHOD: Pregnant women (n=45) were surveyed with scales measuring chronic stress, perceived stress, pregnancy-related and pregnancy-specific anxiety. Hair samples were collected as an objective neuroendocrine measure of chronic stress. Linear regression analyses were performed to assess associations between stress measures and hair cortisol. Pre-pregnancy BMI, smoking during pregnancy, and steroid use during pregnancy were used as covariates in adjusted models. RESULTS: Chronic stress, operationalized as maternal reports of neighborhood/housing strain, daily activities and relationship strain, discrimination, and financial strain, was significantly associated with higher hair cortisol concentrations. No significant associations were found between hair cortisol and perceived stress, pregnancy-related anxiety, nor pregnancy-specific anxiety in adjusted models. CONCLUSION: Chronic stress may be a more robust correlate of physiological stress, as measured by hair cortisol in pregnancy, than other common measures of prenatal stress and anxiety.

Placental corticotrophin-releasing hormone trajectories in pregnancy: Associations with postpartum depressive symptoms.

OBJECTIVE: Depressive symptoms following birth are common and can have adverse effects for mothers, children, and families. Changes in hypothalamic-pituitary-adrenal (HPA) axis regulation during pregnancy may be implicated in the development of postpartum depressive symptoms, particularly changes in placental corticotropinreleasing hormone (pCRH). However, few studies have tested how dynamic pCRH changes over pregnancy relate to postpartum depressive symptoms. This preregistered investigation tests associations of both pCRH levels and changes from early to late pregnancy with postpartum depressive symptoms. METHODS: The sample consists of 173 women studied in early, mid, and late pregnancy who later reported on depressive symptoms with the Edinburgh Postpartum Depression Scale during interviews at 1, 6 and 12 months postpartum. Blood samples were collected at each prenatal timepoint and assayed for pCRH using radioimmunoassay. Latent growth curve analysis was employed to identify distinct trajectories of pCRH during pregnancy. RESULTS: We identified three prenatal pCRH trajectories labeled as typical, flat, and accelerated. Each trajectory showed exponential increases in pCRH levels over the course of gestation but differed in overall levels and rates of change. pCRH levels were not associated with postpartum depressive symptoms. However, women with accelerated pCRH trajectories reported marginally higher depressive symptoms one month postpartum. Primary analysis models adjusted for marital status, income, prepregnancy BMI, parity, prenatal depressive symptoms, and gestational age. CONCLUSIONS: These findings add to our understanding of dynamic changes to maternal HPA axis regulation during pregnancy and contribute to growing evidence on how pCRH changes relate to the development of postpartum depressive symptoms.

Developmental cascades from maternal preconception stress to child behavior problems: Testing multilevel preconception, prenatal, and postnatal influences.

Although maternal stress during pregnancy and even before conception shapes offspring risk for mental health problems, relatively little is known about the mechanisms through which these associations operate. In theory, preconception and prenatal stress may affect offspring mental health by influencing child responses to postnatal caregiving. To address this knowledge gap, this study had two aims. First, we examined associations between preconception and prenatal stress with child temperament profiles at age four using multilevel assessment of maternal perceived stress and stress physiology. Second, we tested child temperament profiles as moderators of associations between observed parenting behaviors during a parent-child free-play interaction when children were 4 years old and child behavior problems 1 year later. Latent profile analyses yielded four distinct child temperament profiles: inhibited, exuberant, regulated low reactive, and regulated high reactive. Consistent with hypotheses, preconception, and prenatal stress each independently predicted the likelihood of children having temperament profiles characterized by higher negative emotionality and lower regulation. Specifically, preconception perceived stress and prenatal cortisol predicted likelihood of children having an exuberant temperament, whereas prenatal perceived stress predicted likelihood of children having an inhibited temperament. Contrary to hypotheses, temperament profiles did not moderate predictions of child behavior problems from observed parenting behaviors; however, responsive parenting behaviors inversely predicted child behavior problems independently of child temperament. These findings add to growing evidence regarding effects of preconception factors on child outcomes and underscore a central role for responsive parenting behaviors in predicting more favorable child mental health independent of child temperament.

Parental preconception posttraumatic stress symptoms and maternal prenatal inflammation prospectively predict shorter telomere length in children.

OBJECTIVE: Parental trauma exposure and trauma-related distress can increase risk for adverse health outcomes in offspring, but the pathways implicated in intergenerational transmission are not fully explicated. Accelerated biological aging may be one mechanism underlying less favorable health in trauma-exposed individuals and their offspring. This study examines associations of preconception maternal and paternal posttraumatic stress disorder (PTSD) symptoms with child telomere length, and maternal prenatal C-reactive protein (CRP) as a biological mechanism. METHODS: Mothers (n = 127) and a subset of the fathers (n = 84) reported on PTSD symptoms before conception. Mothers provided blood spots in the second and third trimester that were assayed for CRP. At age 4, children provided buccal cells for measurement of telomere length. Models adjusted for parental age, socioeconomic status, maternal pre-pregnancy BMI, child biological sex, and child age. RESULTS: Mothers' PTSD symptoms were significantly associated with shorter child telomere length (ß = -0.22, SE = 0.10, p = .023). Fathers' PTSD symptoms were also inversely associated with child telomere length (ß = -0.21, SE = 0.11), though nonsignificant (p = .065). There was no significant indirect effect of mothers' PTSD symptoms on child telomere length through CRP in pregnancy, but higher second trimester CRP was significantly associated with shorter child telomere length (ß = -0.35, SE = 0.18, p = .048). CONCLUSIONS: Maternal symptoms of PTSD prior to conception and second trimester inflammation were associated with shorter telomere length in offspring in early childhood, independent of covariates. Findings indicate intergenerational transmission of parental trauma may occur in part through accelerated biological aging processes and provide further evidence that prenatal pro-inflammatory processes program child telomere length.Open Science Framework Pre-registration:https://osf.io/7c2d5/?view_only=cd0fb81f48db4b8f9c59fc8bb7b0ef97.

Stress before conception and during pregnancy and maternal cortisol during pregnancy: A scoping review.

BACKGROUND: Stress before conception and during pregnancy is associated with less favorable maternal and child health. Alterations in prenatal cortisol levels may serve as a central biological pathway linking stress to adverse maternal and child health. Research examining associations between maternal stress from childhood through pregnancy and prenatal cortisol has not been comprehensively reviewed. METHOD: The current scoping review of 48 papers synthesizes studies reporting on associations between stress before conception and during pregnancy with maternal cortisol in pregnancy. Eligible studies measured childhood, the proximal preconception period, pregnancy, or lifetime stress based on stress exposures or appraisals and measured cortisol in saliva or hair during pregnancy. RESULTS: Higher maternal childhood stress was associated with higher cortisol awakening responses and alterations in typical pregnancy-specific changes in diurnal cortisol patterns across studies. In contrast, most studies of preconception and prenatal stress reported null associations with cortisol and those reporting significant effects were inconsistent in direction. A few studies found that the associations between stress and cortisol during pregnancy varied as a function of several moderators including social support and environmental pollution. CONCLUSIONS: Although many studies have evaluated effects of maternal stress on prenatal cortisol, this scoping review is the first to synthesize existing literature on this topic. The association between stress before conception and during pregnancy and prenatal cortisol may depend on the developmental timing of stress and several moderators. Maternal childhood stress was more consistently associated with prenatal cortisol than proximal preconception or pregnancy stress. We discuss methodological and analytic factors that may contribute to mixed findings.

Childhood family stress modifies the association between perinatal stressful life events and depressive symptoms.

The childhood family environment can influence long-term well-being in part by modifying how individuals' respond to and cope with stress across the life span. Theoretical models propose that childhood stress will either exacerbate (stress sensitization) or attenuate (steeling effect) the effects of adult stress on mental health. This study tests whether childhood family stress modifies the association between stressful life events and depressive symptoms in pregnancy and consecutive postpartum periods. A sample of 127 women reported on depressive symptoms after one birth, during a subsequent pregnancy, and postpartum following that birth. Childhood family stress was assessed with the Risky Families Questionnaire. Stressful life events were measured at all three timepoints to capture the number of life events during both pregnancies and between pregnancies. Associations between stressful life events and depressive symptoms varied as a function of childhood family stress. At the between-persons level, more stressful life events were associated with greater depressive symptoms among women who reported infrequent exposure to childhood family stress in this sample, but not among women who reported more frequent exposure to childhood family stress. Results provide novel evidence that moderate exposure to childhood family stress may attenuate the association between stressful life events and depressive symptoms in the perinatal period, consistent with a steeling effect. That is, some degree of childhood family stress may promote resilience to perinatal stress. Findings underscore the utility of examining the interaction of risk factors across the life span in predicting perinatal mental health. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Maternal Early Life Adversity and Infant Stress Regulation: Intergenerational Associations and Mediation by Maternal Prenatal Mental Health.

Early life adversity is a potent risk factor for poor mental health outcomes across the lifespan, including offspring vulnerability to psychopathology. Developmentally, the prenatal period is a sensitive window in which maternal early life experiences may influence offspring outcomes and demarcates a time when expectant mothers and offspring are more susceptible to stressful and salutary influences. This prenatal plasticity constituted the focus of the current study where we tested the association of maternal early life adversity with infant stress regulation through maternal prenatal internalizing symptoms and moderation by prenatal social support. Mother-infant dyads (n = 162) were followed prospectively and mothers completed assessments of social support and depressive and anxiety symptoms across pregnancy. Infants completed standardized stress paradigms at one month and six months. There were several key findings. First, maternal prenatal depressive symptoms significantly mediated predictions of infant cortisol reactivity to the heel stick at one month from maternal early life adversity: specifically, maternal early life adversity positively predicted depressive symptoms in pregnancy, which in turn predicted dampened infant cortisol reactivity. Second, prenatal social support did not significantly moderate predictions of depressive or anxiety symptoms in pregnancy from maternal early life adversity nor did it alter the associations of maternal depressive or anxiety symptoms with infant stress regulation. These results suggest that maternal prenatal mental health is a key mechanism by which maternal early life adverse experiences affect offspring risk for psychopathology. We discuss potential clinical and health implications of dysregulated infant cortisol reactivity with respect to lifespan development.

Increases in maternal depressive symptoms during pregnancy and infant cortisol reactivity: Mediation by placental corticotropin-releasing hormone.

BACKGROUND: Maternal depressive symptoms in pregnancy may affect offspring health through prenatal programming of the hypothalamic-pituitary-adrenal (HPA) axis. The biological mechanisms that explain the associations between maternal prenatal depressive symptoms and offspring HPA axis regulation are not yet clear. This pre-registered investigation examines whether patterns of maternal depressive symptoms in pregnancy are associated with infant cortisol reactivity and whether this association is mediated by changes in placental corticotropin-releasing hormone (pCRH). METHOD: A sample of 174 pregnant women completed assessments in early, mid, and late pregnancy that included standardized measures of depressive symptoms and blood samples for pCRH. Infant cortisol reactivity was assessed at 1 and 6 months of age. RESULTS: Greater increases in maternal depressive symptoms in pregnancy were associated with higher cortisol infant cortisol reactivity at 1 and 6 months. Greater increases in maternal depressive symptoms in pregnancy were associated with greater increases in pCRH from early to late pregnancy which in turn were associated with higher infant cortisol reactivity. CONCLUSIONS: Increases in maternal depressive symptoms and pCRH over pregnancy may contribute to higher infant cortisol reactivity. These findings help to elucidate the prenatal biopsychosocial processes contributing to offspring HPA axis regulation early in development.

Maternal stress and mental health before pregnancy and offspring diurnal cortisol in early childhood.

The current study investigates whether prepregnancy maternal posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, and stress predict children's cortisol diurnal slopes and cortisol awakening responses (CARs) adjusting for relevant variables. Mothers were enrolled after delivering a baby and followed through their subsequent pregnancy with 5 years of longitudinal data on their subsequent child. This prospective design allowed assessment of PTSD symptoms, depressive symptoms, and perceived stress prior to pregnancy. Children provided three saliva samples per day on three consecutive days at two timepoints in early childhood (M age = 3.7 years, SD = 0.38; M age = 5.04 years, SD = 0.43). Mothers' PTSD symptoms prior to pregnancy were significantly associated with flatter child diurnal cortisol slopes at 4 and 5 years, but not with child CAR. Findings at the age of 4 years, but not 5 years, remained statistically significant after adjustment for maternal socioeconomic status, race/ethnicity, child age, and other covariates. In contrast, maternal prepregnancy depressive symptoms and perceived stress did not significantly predict cortisol slopes or CAR. Results suggest that maternal prepregnancy PTSD symptoms may contribute to variation in early childhood physiology. This study extends earlier work demonstrating risk of adverse outcomes among children whose mothers experienced trauma but associations cannot be disentangled from effects of prenatal mental health of mothers on children's early childhood.

Pregnancy anxiety, placental corticotropin-releasing hormone and length of gestation.

OBJECTIVE: High pregnancy anxiety is a consistent predictor of earlier labor and delivery. Placental corticotropin-releasing hormone (pCRH) predicts earlier delivery consistently and it has been identified as a biological mediator of the association between pregnancy anxiety and gestational length. However, studies have not examined whether changes in pregnancy anxiety are associated with earlier birth as mediated by changes in pCRH during pregnancy. Accordingly, this study tests whether linear changes in pregnancy anxiety are associated with length of gestation indirectly through nonlinear increases in pCRH over pregnancy. METHODS: A sample of pregnant women (n=233) completed prenatal assessments in early pregnancy, second trimester, and third trimester that included a 4-item assessment of pregnancy anxiety and collection of blood samples assayed for pCRH using radioimmunoassay. Length of gestation was abstracted from medical records after birth. RESULTS: Increases in pregnancy anxiety from early pregnancy to third trimester predicted shorted length of gestation, as did nonlinear increases in pCRH over pregnancy. However, there was no evidence of an indirect effect of changes in pregnancy anxiety on length of gestation via changes in pCRH. CONCLUSIONS: These results indicate that linear changes in pregnancy anxiety and nonlinear changes in pCRH during pregnancy are independent risk factors for shortened gestational length. This study adds to a small but growing body of work on biopsychological processes in pregnancy and length of gestation. Modeling changes in psychological and biological processes during pregnancy could provide more insight into understanding risk for adverse pregnancy outcomes.

Maternal depressive symptom trajectories from preconception through postpartum: Associations with offspring developmental outcomes in early childhood.

BACKGROUND: Two theoretical frameworks, the cumulative stress and match-mismatch model, propose that patterns of maternal depressive symptoms over early periods of offspring development predict outcomes in opposing ways. Studies have yet to test these theories across the preconception, prenatal, and early postnatal period. Study 1 identified trajectories of maternal depressive symptoms from preconception to postpartum. Study 2 examined associations of these trajectories with offspring developmental outcomes in early childhood. METHODS: In Study 1, women (n = 362) enrolled in a longitudinal study were assessed prior to conception and through a subsequent pregnancy and postpartum. In Study 2, a subsample of 125 mother-child pairs completed home visits in early childhood. Mothers reported on child temperament at age 4. Children completed assessments of executive function at age 5. RESULTS: Four trajectories of maternal depressive symptoms were identified: low-stable, increasing, decreasing, persistent. In controlled analyses, children of women with decreasing symptoms were lower in maternal ratings of effortful control at age four (ß = -0.24, p = .003). Children of women with increasing symptoms scored lower on an inhibitory control task at age five (ß = -0.35, p = .001). CONCLUSIONS: Changes in maternal depressive symptoms, but not stable symptoms, were associated with lower maternal ratings of effortful control and poorer performance on an inhibitory control task. Results are consistent with the match-mismatch model. Assessment of preconception depressive symptoms in women and changes in symptoms may be beneficial for early intervention for women and children.

Using probabilistic record linkage and propensity-score matching to identify a community-based comparison population.

In retrospective cohort studies of interventions disseminated to communities, it is challenging to find comparison groups with high-quality data for evaluation. We present one methodological approach as part of our study of birth outcomes of second-born children in a home visiting (HV) program targeting first-time mothers. We used probabilistic record linkage to link Connecticut's Nurturing Families Network (NFN) HV program and birth-certificate data for children born from 2005 to 2015. We identified two potential comparison groups: a propensity-score-matched group from the remaining birth certificate sample and eligible-but-unenrolled families. An analysis of interpregnancy interval (IPI) is presented to exemplify the approach. We identified the birth certificates of 4822 NFN families. The propensity-score-matched group had 14,219 families (3-to-1 matching) and we identified 1101 eligible-but-unenrolled families. Covariates were well balanced for the propensity-score-matched group, but poorly balanced for the eligible-but-unenrolled group. No program effect on IPI was found. By combining propensity-score matching and probabilistic record linkage, we were able to retrospectively identify relatively large comparison groups for quasi-experimental research. Using birth certificate data, we accessed outcomes for all of these individuals from a single data source. Multiple comparison groups allow us to confirm findings when each method has some limitations. Other researchers seeking community-based comparison groups could consider a similar approach.

Birth-Related Outcomes for Second Children Following Home Visiting Program Enrollment for New Parents of First Children.

INTRODUCTION: Home visiting (HV) programs aim to promote child and family health through perinatal intervention. HV may benefit second children through improving subsequent pregnancy and birth outcomes. However, HV impacts on birth outcomes of second children have not been examined in a naturalistic setting. METHODS: Using data from Connecticut Nurturing Families Network (NFN) home visiting program of families enrolled from 2005 to 2015, we compared birth-related outcomes (birthweight, preterm birth, Cesarean section delivery, prenatal care utilization) of second children (n = 1758) to demographically similar propensity-score-matched families that were not enrolled in NFN (n = 5200). We examined whether the effects of NFN differed by maternal age, race and ethnicity, or visit attendance pattern. RESULTS: There was no program effect for the full sample. The effect of NFN did not differ by maternal age or visit attendance pattern but did differ by maternal race and ethnicity. Black women in NFN were more likely to receive adequate prenatal care during their second pregnancy (OR 1.05; 95% CI 1.01, 1.09) and Hispanic women in NFN were less likely to deliver by Cesarean section for their second birth (OR 0.97; 95% CI 0.94, 0.99), compared to Black and Hispanic women in the comparison group respectively. There was a protective program effect on prematurity of the second child (OR 0.92; 95% CI 0.85, 0.996) for women with a preterm first birth. DISCUSSION: These findings suggest that benefits of HV extend to subsequent birth-related outcomes for women from marginalized racial/ethnic groups. HV may help buffer some harmful social determinants of health.

Skills-homework completion and phone coaching as predictors of therapeutic change and outcomes in completers of a DBT intensive outpatient programme.

OBJECTIVES: Dialectical behaviour therapy (DBT) emphasizes generalization of skills to the patient's real-world context as a primary mechanism of change in treatment. To promote generalization, DBT includes weekly skills-focused homework assignments and as-needed phone coaching. Despite this central function of generalization in DBT, research on these treatment components is limited. The current study addresses this research gap by assessing the association of homework and phone coaching to DBT treatment outcomes. DESIGN: A longitudinal study design explored the extent to which (a) completion of skills homework and (b) frequency of phone coaching were associated with therapeutic changes and treatment outcomes in a DBT intensive outpatient programme (DBT-IOP). METHOD: Medical records and diary cards of 56 patients who had completed a four-month treatment cycle of DBT-IOP were reviewed and coded for proportion of skills homework completed, frequency of phone coaching calls, and reported urges for and engagement in suicide, non-suicidal self-injury, illicit or non-prescribed substance use, and alcohol use behaviours. RESULTS: Completion of skills homework and frequency of phone coaching were significantly associated with (a) reduced urges for suicide, non-suicidal self-injury, illicit or non-prescribed substance use, and alcohol use from the beginning to end of treatment and (b) a lower likelihood of engaging in any of these behaviours during the final month of treatment. CONCLUSIONS: Results suggest that within a DBT programme modified for an intensive outpatient setting, skills homework and phone coaching may enhance therapeutic change and outcomes in target behaviours. These generalization methods appear to be important ingredients of DBT effectiveness. PRACTITIONER POINTS: In dialectical behaviour therapy (DBT), therapeutic skills homework and phone coaching are specifically designed to promote generalization of skills from the therapeutic context to the patient's real-world contexts. In a DBT intensive outpatient programme, patient engagement with therapeutic homework and phone coaching were associated with favourable therapeutic change and outcomes in target urges and behaviours. Clinicians may consider a patient's lack of homework completion and/or phone coaching to be early warning signs of poor therapeutic progress within dialectical behaviour therapy.

Depression, family interaction and family intervention in adolescents at clinical-high risk for psychosis.

AIM: The relationship between family behaviour and depression in adolescents at clinical high risk (CHR) for psychosis remains understudied despite high rates of depression in this population. This study examines the relationship between family problem-solving behaviours and depression in CHR adolescents and the impact of family interventions targeting subthreshold symptoms of psychosis on reducing symptoms of depression over 2-years. METHODS: Participants were a subset of the North American Prodrome Longitudinal Study who were randomized to 6-months of family focused therapy for individuals at CHR or family psychoeducational treatment. We evaluated the relationship between communication during family conflict discussion and adolescents' symptoms of depression before treatment. At follow-up assessments the family treatment groups were compared on depression. Finally, we compared those in family treatment with matched controls. RESULTS: Adolescents' constructive communication was associated with less severe symptoms of depression before treatment. Symptoms of depression improved for adolescents in both family treatment groups. However, there were no significant group by treatment interactions. When adolescents who participated in either type of family intervention were compared to CHR adolescent controls, symptoms of depression improved for adolescents in treatment and control groups, but there were no significant time by treatment interactions. CONCLUSIONS: The communication skills of CHR adolescents are related to both depression and their parents' communication skills pre-treatment. However, reductions in depression over the course of the treatment trial cannot be attributed to family treatment. It is imperative to incorporate interventions that directly target depression into future family treatment studies.
