Maternal depressed mood and serotonergic antidepressant treatment during pregnancy differentially shape the continuity between fetal–newborn neurobehaviour

BackgroundPrenatal serotonin reuptake inhibitor (SRI) antidepressant exposure is associated with newborn neurobehavioural disturbances, but it remains unclear whether this reflects a transient pharmacologic condition or an altered neurodevelopmental trajectory emerging in utero from sustained gestational SRI exposure. AimThis study explored longitudinal relationships between third-trimester fetal physiology and newborn neurobehaviour, and determined whether early neurobehavioural continuity is shaped by prenatal SRI or depression exposure. MethodsParticipants were 127 pregnant mothers and their fetal-newborn offspring. Four groups were defined based on antenatal depressive symptoms and SRI treatment: Control (n = 51), Depressed (unmedicated; n = 35), SRI-Depressed (n = 26) and SRI-Non-Depressed (n = 15). Doppler measures of fetal heart rate (fHR), motor activity and vascular hemodynamics were obtained at 36-weeks' gestation, then newborn neurobehavioural maturity was evaluated at postnatal day-7. Partial least squares analysis was used to identify latent correlations between fetal-newborn measures; associations were further studied with hierarchical regression testing group moderation. ResultsTwo dimensions described 74% of the covariance between fetal physiologic and newborn neurobehavioural measures (permuted p < 0.05). Three latent fetal-newborn relationships were significantly moderated by group: (1) lower fHR variability, and (2) greater fHR decelerations, predicted lower alertness/orientation scores but only in SRI-Depressed-group newborns; and (3) lower fetal cerebrovascular resistance predicted lower motor scores in Depressed-group newborns. SRI treatment to euthymia was not associated with fetal-newborn neurobehavioural disturbances. ConclusionsMaternal depression, both unmedicated and SRI-treated with persistent/poorly-managed mood symptoms, differentially shaped fetal-newborn neurobehavioural continuity. These findings suggest that neurobehavioural disturbances may predate birth, and underscore the importance of effective mental health management during pregnancy.

Pathways between parental depressed mood and child cognition in economically marginalized populations

Research supports parental depressed mood, negative parenting, and family conflict as risk factors for poorer cognition in early childhood. The current study is the first to examine bidirectional associations between maternal and paternal depressed mood, negative maternal and paternal parenting, family conflict, and child cognition. Data was drawn from the Early Head Start Research and Evaluation study using interviews, self-report, and performance-based measures completed by parents when children were age 14 months, age 2 years, and age 3 years. Results showed bidirectional pathways between maternal depressed mood and child cognition, but a unidirectional pathway from child cognition to paternal depressed mood. Family conflict mediated links between greater maternal depressed mood and poorer child cognition, but negative maternal parenting mediated links between poorer child cognition and negative maternal depressed mood. Results highlight transactional relations among parents and children as well as the salience of family conflict and negative parenting in exacerbating this transaction.

The Concurrent and Longitudinal Relationship between Perinatal Sleep Difficulties and Depression in a Large Sample of High-Risk Women in South Africa.

Perinatal depression and sleep difficulties are common among studies conducted in high income countries (HIC). This study examines the relationship between sleep difficulties and depression during the perinatal period and over an eight-year follow-up period in South Africa, a middle income country. A population cohort of 1238 pregnant women (mean age = 26.33) in 24 township neighborhoods in South Africa were recruited and reassessed six times over the next 8years post birth with follow-up rates of 96-83%. The relationship between maternal depressed mood and sleep difficulties was examined over time, as well as the relationship of sleep with other socioeconomic, environmental, and psychiatric risk factors. Thirty-five percent of the women reported sleep difficulties during the perinatal period; whereas only 8% reported sleep difficulties at 8-year follow-up. Perinatal sleep difficulties were associated with lower income, lower educational attainment, less access to electricity, more food insecurity, higher rates of interpersonal violence and HIV, alcohol consumption, and depressed mood at 8years. However, the severity of depressed mood was the strongest predictor of sleep problems longitudinally and cross-sectionally, after accounting for all other risk factors. We found that the severity of depressed mood is highly associated with sleep difficulties from pregnancy to 8years post-birth and in a linear relationship, so that higher depressed mood is associated with more sleep problems.

Impact of Parental Mental Health and Help-Seeking on Adolescents' Suicidal Ideations and Help-Seeking Behaviors.

This study aimed to evaluate the impact of parental mental health on adolescent offspring. Data regarding 6512 families from the 2010-2021 Korean National Health and Nutrition Examination Survey were analyzed; among them, 428 were placed in the suicidal ideation (SI) group and 421 were placed in the matched control (MC) group. This number was selected for the use of the propensity score matching method. The findings highlighted significant associations between parental mental health and adolescent suicidal ideation, with mothers in the SI group having higher odds of Diagnosed Depression (OR 2.109, 1.023-4.350 95% CI), Depressive Mood (OR 2.155, 1.224-3.793 95% CI), and Suicidal Ideation (OR 2.532, 1.322-4.851 95% CI) compared to the MC group. Regarding the fathers, paternal Suicidal Ideation (OR 4.295, 1.747-10.599 95% CI) was the only significant factor for adolescent suicidal ideation. In contrast, maternal depressive symptoms and help-seeking behavior significantly impacted adolescent help-seeking; Maternal Depressive Mood increased with adolescent Help-Seeking (OR 4.486, 1.312-15.340 95% CI) while Maternal Suicidal Ideation reduced the probability of Help-Seeking in the SI group (OR 0.15, 0.031-0.721, 95% CI). Chronic and severe depressive symptoms in mothers could make adolescents less likely to seek help for their suicidal ideations. Therefore, clinicians working with adolescents should prioritize a family-oriented approach.

Daily relationships among maternal rumination, mood and bonding with infant

There is little research examining the association between maternal maladaptive emotion regulation strategies such as rumination and perceived maternal bonding and mood. This study investigated the concurrent and prospective relationship of both trait and daily rumination with daily perceived maternal bonding and mood. Ninety-three mothers of infants aged between 3 and 14 months completed a ten-day diary study investigating the relationship between daily and trait ruminative self-focus, negative affect and perceived maternal bonding, or her perceived feelings of closeness with her infant. The majority of mothers reported mild to moderate depressive symptoms. The data were analysed using Hierarchical Linear Modelling. Baseline depressive symptoms and trait rumination were each positively associated with mean levels of daily ruminative self-focus and mood over the ten-day sampling period. Bonding with infant at baseline was not associated with mean levels of daily rumination, mood or bonding over the sampling period. Concurrently, daily rumination and daily bonding were negatively correlated, after accounting for daily mood. Prospectively, lower levels of daily bonding predicted increases in daily rumination and depressive mood on the subsequent day. Interestingly, daily rumination did not predict increases in depressive mood or bonding on the subsequent day, suggesting that rumination occurred in response to perceived disruptions in feelings of closeness with the infant, but did not lead to prospective decreases in these feelings of closeness. These findings hold important implications for understanding the relationship between the mother-infant relationship, and maternal rumination and depressive mood, suggesting that disruptions in the way mothers perceive they are bonding to their infants may contribute to depressongenic processes.

Maternal mental health and the behavior of children with autism spectrum disorder: Unidirectional and bidirectional effects

BackgroundWhile transactional theories of development posit that child and parent functioning are reciprocally linked, few autism family studies have examined if and how differing domains of child behavior and parental mental health may mutually affect one another over time. MethodData was collected over three time-points spanning four years from a sample of 119 mothers of children with ASD (aged 7–11 years at baseline). Cross-lagged structural equation models tested whether child problem or prosocial behavior was reciprocally related to three domains of maternal mental health: depressed mood, anger, and positive emotional well-being. ResultsFindings provided mixed support for bidirectionality as reciprocal relationships were found only in models examining relations between maternal depressed mood and child problem and prosocial behavior. Apart from these two bidirectional relationships, all other significant cross-lagged effects were unidirectional and parent-driven, with prior levels of maternal mental health impacting later child behavior rather than the reverse. ConclusionStudy results add to the limited evidence base concerning directionality of parent-child effects in autism family research. Given the intertwined nature of child and maternal functioning found in this study, there is clearly a need for additional family-based interventions that target both parents and their autistic children.

Associations between maternal depressive symptoms and selective serotonin reuptake inhibitor antidepressant treatment on internalising and anxiety behaviours in children: 12-year longitudinal study

Prenatal selective serotonin reuptake inhibitor (SSRI) antidepressant exposure is associated with increased internalising and anxious behaviours in young children; whether this continues into early adolescence is unknown. Also, it is not well established whether it is the in utero exposure to SSRIs or the underlying maternal mood that contributes more to these associations. To examine associations between maternal depressive symptoms, prenatal SSRI antidepressant treatment and internalising and anxiety behaviours from childhood into pre-adolescence. From a prospective longitudinal cohort, measures of maternal depressive symptoms and SSRI use and child outcomes (n = 191 births) were obtained from the second trimester to 12 years. Maternal reports of internalising and anxiety behaviours in children were obtained at 3, 6 and 12 years. Multilevel mixed-effects models revealed that maternal depressed mood at the third trimester assessment, not prenatal SSRI exposure, was associated with longitudinal patterns of higher levels of internalising and anxiety behaviours across childhood from 3 to 12 years of age. At each age, hierarchical regressions showed that maternal mood at the third trimester, compared with current maternal depression or prenatal SSRI exposure, explained a greater proportion of the variance in internalising and anxiety behaviours. Even with prenatal SSRI treatment, maternal depressed mood during the third trimester still had an enduring effect as it was associated with increased levels of internalising and anxiety behaviours across childhood and into early adolescence. Importantly, we found no evidence of a 'main effect' association between prenatal SSRI exposure and internalising and anxiety behaviours in children.

A pilot feasibility study of Conexiones, a telephone-delivered cancer parenting education program for Hispanic mothers

Objective To test the short-term impact of Conexiones, a culturally adapted cancer parenting education program for diagnosed child-rearing Hispanic mothers. Design Single group, pre-post-test design. Sample 18 U.S. Hispanic mothers diagnosed within 2 years with early-stage cancer (0–III) raising a child (5–17 years). Methods Participants completed consent, baseline measures, and five telephone-delivered Conexiones sessions at 2-week intervals from trained patient educators in English or Spanish. Outcomes were assessed at baseline and at 3 months. Results Maternal depressed mood, parenting self-efficacy, and parenting quality significantly improved. Children’s anxious/depressed mood tended to significantly improve. Outcomes did not co-vary with mothers’ level of acculturation. Conclusions Conexiones appears to positively improve Hispanic mothers’ distress and parenting competencies; efficacy testing is warranted within a larger randomized control trial. Implications for Psychosocial Providers A brief, culturally adapted cancer parenting education program has potential to enhance Hispanic mothers’ and children’s behavioral-emotional adjustment to a mother’s cancer.

Preschoolers' emotion reactivity and regulation: Links with maternal psychological distress and child behavior problems.

Maladaptive offspring emotion regulation has been identified as one pathway linking maternal and child psychological well-being in school-aged children. Whether such a pathway is present earlier in life still remains unclear. The present study investigated the role of preschoolers' emotion reactivity and regulation in the association between maternal psychological distress and child internalizing and externalizing problems. Children's emotion reactivity and regulation were assessed through both observed behavior and physiology. At 42 months of age, children (n = 251; 128 girls) completed a fear induction task during which their heart-rate variability was assessed and their behavior was monitored, and maternal self-reports on depressive mood and anxiety were collected. At 48 months mothers and fathers reported on their children's internalizing and externalizing problems. Higher maternal depressive mood was associated with lower child fear-related reactivity and regulation, as indexed by heart-rate variability. The latter mediated the association between higher maternal depressive mood and higher preschoolers' externalizing problems. Overall, our findings support the role of preschoolers' emotion reactivity and regulation in the relationship between maternal psychological distress and children's socio-emotional difficulties. This role may also depend on the discrete emotion to which children react or seek to regulate as, here, we only assessed fear-related reactivity and regulation.

Maternal Serotonin Reuptake Inhibitor Antidepressants Have Acute Effects on Fetal Heart Rate Variability in Late Gestation.

Background: Prenatal exposure to serotonin reuptake inhibitor (SRI) antidepressants increases risk for adverse neurodevelopmental outcomes, yet little is known about whether effects are present before birth. In relation to maternal SRI pharmacokinetics, this study investigated chronic and acute effects of prenatal SRI exposure on third-trimester fetal heart rate variability (HRV), while evaluating confounding effects of maternal depressed mood.Methods: At 36-weeks' gestation, cardiotocograph measures of fetal HR and HRV were obtained from 148 pregnant women [four groups: SRI-Depressed (n = 31), SRI-Non-Depressed (n = 18), Depressed (unmedicated; n = 42), and Control (n = 57)] before, and ~5-h after, typical SRI dose. Maternal plasma drug concentrations were quantified at baseline (pre-dose) and four time-points post-dose. Mixed effects modeling investigated group differences between baseline/pre-dose and post-dose fetal HR outcomes. Post hoc analyses investigated sex differences and dose-dependent SRI effects.Results: Maternal SRI plasma concentrations were lowest during the baseline/pre-dose fetal assessment (trough) and increased to a peak at the post-dose assessment; concentration-time curves varied widely between individuals. No group differences in fetal HR or HRV were observed at baseline/pre-dose; however, following maternal SRI dose, short-term HRV decreased in both SRI-exposed fetal groups. In the SRI-Depressed group, these post-dose decreases were displayed by male fetuses, but not females. Further, episodes of high HRV decreased post-dose relative to baseline, but only among SRI-Non-Depressed group fetuses. Higher maternal SRI doses also predicted a greater number of fetal HR decelerations. Fetuses exposed to unmedicated maternal depressed mood did not differ from Controls.Conclusions: Prenatal SRI exposure had acute post-dose effects on fetal HRV in late gestation, which differed depending on maternal mood response to SRI pharmacotherapy. Importantly, fetal SRI effects were sex-specific among mothers with persistent depressive symptoms, as only male fetuses displayed acute HRV decreases. At trough (pre-dose), chronic fetal SRI effects were not identified; however, concurrent changes in maternal SRI plasma levels suggest that fetal drug exposure is inconsistent. Acute SRI-related changes in fetal HRV may reflect a pharmacologic mechanism, a transient impairment in autonomic functioning, or an early adaption to altered serotonergic signaling, which may differ between males and females. Replication is needed to determine significance with postnatal development.

Maternal depressed mood and child development over the first five years of life in South Africa

BackgroundWhile the negative impact of peri-natal depression is well-documented in high-income countries, the long-term effects across the life course in low and middle-income countries is less clear. Children's adjustment over the first five years is examined as a function of patterns of maternal depressed mood. MethodsPregnant women in 24 peri-urban townships (N = 1,238) were randomized to a home-visiting intervention or standard care and reassessed five times, with high retention. There were no intervention effects on children past 18 months. Multilevel regression models examined the impact of depressed mood on child outcomes. Using the Edinburgh Postnatal Depression Scale, four patterns of maternal depressed mood were identified: never (40.6%); antenatal (13.0%); early childhood (26.1%); and recurrent episodes of depressed mood (20.3 %). FindingsMothers' patterns of depressive symptoms and child outcomes were similar, regardless of intervention. Never depressed mothers were significantly younger, had higher income, less food insecurity, were more likely to have electricity, be living with HIV or have an HIV positive partner, and had fewer problems with alcohol than depressed mothers. Children of mothers who experienced depressed mood weighed less, were more aggressive, and were hospitalized more often than children of never depressed mothers, but were similar in cognitive and social development. InterpretationsDepressed mood, has significant negative impacts on South African children's growth and aggressive behavior. The timing of maternal depressed mood was less important than never having a depressed mood or a recurrent depressed mood. FundingThere were no funding conflicts in executing this trial.

First 1,000 days: enough for mothers but not for children? Long-term outcomes of an early intervention on maternal depressed mood and child cognitive development: follow-up of a randomised controlled trial.

Child cognitive development is often compromised in contexts of poverty and adversity, and these deficits tend to endure and affect the child across the life course. In the conditions of poverty and violence that characterise many low- and middle-income countries (LMIC), the capacity of parents to provide the kind of care that promotes good child development may be severely compromised, especially where caregivers suffer from depression. One avenue of early intervention focuses on the quality of the early mother-infant relationship. The aim of this study was to examine the long-term impact of an early intervention to improve the mother-infant relationship quality on child cognitive outcomes at 13 years of age. We also estimated the current costs to replicate the intervention. We re-recruited 333 children from an early childhood maternal-infant attachment intervention, 'Thula Sana', when the children were 13 years old, to assess whether there were impacts of the intervention on child cognitive outcomes, and maternal mood. We used the Kaufman Assessment Battery to assess the child cognitive development and the Patient Health Questionnaire (PHQ-9) and the Self-Reporting Questionnaire (SRQ-20) to assess maternal mental health. Effect estimates indicated a pattern of null findings for the impact of the intervention on child cognitive development. However, the intervention had an effect on caregiver psychological distress (PHQ-9, ES = -0.17 [CI: -1.95, 0.05] and SRQ-20, ES = -0.30 [CI: -2.41, -0.19]), but not anxiety. The annual cost per mother-child pair to replicate the Thula Sana intervention in 2019 was estimated at ZAR13,365 ($780). In a socio-economically deprived peri-urban settlement in South Africa, a home visiting intervention, delivered by community workers to mothers in pregnancy and the first six postpartum months, had no overall effect on child cognitive development at 13 years of age. However, those caregivers who were part of the original intervention showed lasting improvements in depressed mood. Despite the fact that there was no intervention effect on long-term child outcomes, the improvements in maternal mood are important.

Effects of maternal depression and prenatal SSRI exposure on executive functions and susceptibility to household chaos in 6-year-old children: prospective cohort study.

Maternal depressed mood during pregnancy may shape a child's adaptation to their environment and engagement in goal-directed behaviour such as executive functions. Whether everyday household context also alters executive functions in children with prenatal selective serotonin reuptake inhibitor (SSRI) antidepressant exposure remains to be determined. To examine the impact of prenatal depressed maternal mood and SSRI exposure on child executive functions and to determine whether these exposures shape a susceptibility to household chaos. A prospective cohort study of mothers and their children (118 mother-children dyads (47 SSRI-exposed, 71 non-exposed)) followed from the second trimester to 6 years. Regression models examined relationships between maternal depressed mood and household chaos on maternal report of child executive functions. Competitive-confirmatory regression models examined whether children were susceptible to household chaos or were positively influenced by less chaos. Prenatal SSRI exposure, third-trimester maternal depressed mood and household chaos in a three-way interaction were associated with executive functions within a model of differential susceptibility. When household chaos was low, children of non-prenatally depressed mothers had better executive function than children of prenatally depressed mothers, regardless of whether the mothers were SSRI-treated. However, when household chaos was high, SSRI-exposed children of mothers who were not depressed during pregnancy had poorer executive functions at 6 years of age compared with SSRI-exposed children whose mothers were symptomatic during pregnancy. The impact of household chaos depended on whether mothers were prenatally depressed and whether mothers were SSRI-treated.

Intimate Partner Violence and Food Insecurity Predict Early Behavior Problems Among South African Children over 5-years Post-Birth.

Households experiencing intimate partner violence (IPV) and food insecurity are at high risk of lifelong physical and behavioral difficulties. Longitudinal data from a perinatal home-visiting cluster-randomized controlled intervention trial in South Africa townships were used to examine the relationships between household settings and mothers' histories of risk and children's behavior problems at 3 and 5years of age. IPV, food insecurity, maternal depressed mood, and geriatric pregnancy (at age of 35 or older) were consistently associated with children's internalizing and externalizing behavior problems. Aggressive behavior was more prevalent among 3- and 5-year olds boys, and was associated with maternal alcohol use. The effects of these factors on child behavior were more prominent than maternal HIV status. There is a continuing need to reduce IPV and household food insecurity, as well as supporting older, depressed, alcohol using mothers in order to address children's behavioral needs.

Hair cortisol in pregnancy interacts with maternal depressive symptoms to predict maternal disrupted interaction with her infant at 4 months.

Disrupted maternal interaction in early infancy is associated with maladaptive child outcomes. Thus, identifying early risk factors for disrupted interaction is an important challenge. Research suggests that maternal depressive symptoms and maternal cortisol dysregulation are associated with disrupted maternal interaction, but both factors have rarely been considered together as independent or interactive predictors of disrupted interaction. In a sample of 51 women, hair cortisol concentrations (HCC) and depressive symptoms were assessed during pregnancy, and depressive symptoms were assessed again at 4-month postpartum. Maternal disrupted interaction was assessed during the Still-Face Paradigm at 4months. Results indicated that HCC and depressive symptoms interacted to predict both maternal withdrawing and inappropriate/intrusive interaction. Withdrawing interaction was associated with high levels of HCC in pregnancy in the context of high depressive symptoms at 4months; inappropriate/intrusive interaction was associated with high levels of HCC in the context of low depressive symptoms. Thus, high HCC potentiated both forms of disrupted interaction. Results raised questions about the meaning of very low reported depressive symptoms, and underscored the importance of chronic stress physiology and maternal depressed mood as risk factors for distinct forms of maternal disrupted interaction, both of which are deleterious for infant development.

Impact of Age at Childbirth on Maternal Mental Health among Premenopausal Women: The 2010-2012 Korean National Health and Nutrition Examination Survey.

ObjectiveNo reports have investigated the influence of age at first or last childbirth on maternal mental health. The aim of this study was to determine whether there is an association between age at first or last childbirth and the mental health of premenopausal women. MethodsThe data used in this study were collected from the 2010 to 2012 Korea National Health and Nutrition Examination Surveys. A total of 3,370 premenopausal women were considered. The association between childbirth age and maternal mental health factors, including stress, depressed mood, and suicidal ideations were analyzed using multiple logistic regression analyses adjusted for confounding factors. ResultsAfter adjusting confounding factors, younger maternal age at first childbirth was found to be associated with an increase in the prevalence of maternal depressed mood and suicidal ideations. Also, older maternal age at last childbirth was related to an increase in maternal stress, depressed mood and suicidal ideations. ConclusionBoth younger first childbirth and older last childbirth maternal age may be risk factors for poor outcomes of premenopausal women’s mental health. These data support the need for comprehensive mental health assessment for premenopausal women who either gave birth at an age too young or too old.

Public interest through web search trends of neuromodulation treatments in the United States

Maternal antenatal depression may alter offspring neurodevelopment, but long follow-up studies are lacking. We studied the risks for mood disorders and schizophrenia in adult offspring of antenatally depressed mothers, taking account parental severe mental disorders.In the general population-based Northern Finland 1966 Birth Cohort with 12,058 children, 13.9% of the mothers reported themselves depressed at mid-gestation. The offspring were followed 43 years. Severe mood disorders and schizophrenia in the offspring and severe mental disorders in the parents were detected using the Care Register for Healthcare. Maternal smoking during pregnancy, perinatal complications, fathers´ social class, family type at birth, and grand multiparity were considered as confounding variables.The offspring of antenatally depressed mothers had an elevated risk for depression (adjusted OR 1.5; 95% CI 1.03–2.2), compared to cohort members without maternal antenatal depressed mood. The offspring with maternal antenatal depressed mood and parental severe mental disorder had markedly elevated risks for depression (3.3; 1.8–6.2), and schizophrenia (3.9; 2.0–7.5), compared to the offspring without one or both of these risk factors.Maternal antenatal depressed mood was determined by one question and did not necessarily signify a clinical condition. Data on maternal postnatal mood was not available.The offspring with maternal antenatal depressed mood and parental severe mental disorder had high risk for depression and schizophrenia. Early interventions in parental severe mental disorder might present an opportunity for decreasing the risk for mood disorders and schizophrenia in the offspring.

Role of psychosocial risk factors in predicting maternal and paternal depressive symptomatology during pregnancy.

The aim of the present study was to investigate the role of several psychosocial risk factors in predicting depressive symptomatology during pregnancy in mothers and fathers, respectively. A total of 146 primiparous mothers and 105 primiparous fathers reporting a psychosocial risk condition were recruited independently from maternity and child health services, during the second trimester of pregnancy. All parents were evaluated for depressive symptomatology, anxiety, and perceived social support. Two hierarchical multiple regression analyses were performed to determine the role of psychosocial factors in predicting depressive symptomatology during pregnancy, in mothers and fathers. Marital dissatisfaction, personal history of depression, and personal trait anxiety were identified as significant predictors of depressive symptomatology during pregnancy, both in mothers and in fathers. Family history of substance abuse, conflictual relationship with the parents in the past year, and bereavement in the past year were identified as significant factors contributing to elevated depressive symptoms during pregnancy in mothers, but not fathers. In this study, several psychosocial risk factors were consistently related to an increase in maternal and paternal depressive symptoms during pregnancy; some of these factors seem to be specifically related to maternal depressive mood.

Home Visiting and Antenatal Depression Affect the Quality of Mother and Child Interactions in South Africa.

To examine whether maternal depressed mood at birth moderated the protective effect of a home-visiting intervention on the quality of caregiving for children growing up in a low- and middle-income country. Almost all pregnant mothers in 24 Cape Town neighborhoods were recruited into a cluster randomized controlled trial matched by neighborhoods to the Philani home-visiting condition (HVC) or the standard care condition (SC). At 3 years after birth, the quality of mother-child interactions between HVC and SC mothers with and without antenatal depressed mood was assessed in a representative subset by rating videotaped observations of mother-child interactions on 10 dimensions of caregiving. As predicted, maternal depressed mood at birth moderated the effect of the HVC on the quality of mother-child interactions. Among nondepressed mothers, mothers and their children in the HVC scored significantly higher on 5 of the 10 dimensions of the maternal-child interaction scale than mothers in the SC: mothers exhibited more maternal sensitivity, talked more, had more harmonious interactions, and had children who paid more attention and exhibited more positive affect. However, being in the HVC did not significantly affect the mother-child interaction scores among mothers with depressed mood. Among HVC children, those with mothers with depressed mood showed significantly less positive affect and talked less with their mothers than children with nondepressed mothers. SC children with mothers with depressed mood were more responsive and paid attention to their mothers than children with nondepressed mothers. Home visiting resulted in a better quality of caregiving for mothers without depressive symptoms. Future interventions need to specifically target maternal depression and positive mother-child interactions.

Severe mood disorders and schizophrenia in the adult offspring of antenatally depressed mothers in the Northern Finland 1966 Birth Cohort: Relationship to parental severe mental disorder

BackgroundMaternal antenatal depression may alter offspring neurodevelopment, but long follow-up studies are lacking. We studied the risks for mood disorders and schizophrenia in adult offspring of antenatally depressed mothers, taking account parental severe mental disorders. MethodsIn the general population-based Northern Finland 1966 Birth Cohort with 12,058 children, 13.9% of the mothers reported themselves depressed at mid-gestation. The offspring were followed 43 years. Severe mood disorders and schizophrenia in the offspring and severe mental disorders in the parents were detected using the Care Register for Healthcare. Maternal smoking during pregnancy, perinatal complications, fathers´ social class, family type at birth, and grand multiparity were considered as confounding variables. ResultsThe offspring of antenatally depressed mothers had an elevated risk for depression (adjusted OR 1.5; 95% CI 1.03–2.2), compared to cohort members without maternal antenatal depressed mood. The offspring with maternal antenatal depressed mood and parental severe mental disorder had markedly elevated risks for depression (3.3; 1.8–6.2), and schizophrenia (3.9; 2.0–7.5), compared to the offspring without one or both of these risk factors. LimitationsMaternal antenatal depressed mood was determined by one question and did not necessarily signify a clinical condition. Data on maternal postnatal mood was not available. ConclusionThe offspring with maternal antenatal depressed mood and parental severe mental disorder had high risk for depression and schizophrenia. Early interventions in parental severe mental disorder might present an opportunity for decreasing the risk for mood disorders and schizophrenia in the offspring.
