Maternal depression and mental health in early childhood: an examination of underlying mechanisms in low-income and middle-income countries

Creating Family-Centred Support for Preschoolers with Developmental Disabilities in Low-Income Countries: A Rapid Review to Guide Practitioners

Preschoolers with disabilities and their caregivers have been neglected in health and social service provision in most low-income countries and arguably also in low-resourced areas of more affluent nations. Yet as this rapid review of the published literature identifies, there are low-cost, evidence-based strategies to address their needs that can be implemented in communities by local people. Five key features of the necessary supports are examined. First, the leadership functions required to create and implement the support services. Second, the family-centred, home-based support provided to caregivers and the personnel undertaking this form of support. Third, providing opportunities for peer support to flourish and encouraging the formation of advocacy groups across families. Fourth, mobilizing the support of significant groups within the community: notably, traditional healers and leaders, health services and poverty alleviation initiatives. Fifth, devising ways in which preschool educational opportunities can be offered to children as a prelude to their inclusion in primary schools. The review serves a further purpose. It provides an example of how public health researchers and academics could achieve more rapid implementation of evidence-based knowledge into existing and new support services through dissemination to community practitioners.

Effect of postpartum depression and role of infant feeding practices on relative weight of child at 1 and 3 years of age

BACKGROUND

Childhood obesity has increased and is considered one of the most serious public health challenges of the 21st century globally, and may be exacerbated by postpartum depression (PPD). The purpose of this study was to examine the association between PPD at 1st and 6th month postpartum, infant feeding practices, and body mass index (BMI) z-score of the child at one and three years of age.

METHODS

This study used data from an ongoing prospective maternal-child birth cohort performed at the National Center for Child Health and Development (NCCHD) in suburban Tokyo, Japan with the period of recruitment from May 13, 2010 to November 28, 2013. Out of 2,309 total number of mothers, 1,279 mother-child dyads were assessed in the study. We performed multivariable linear regression analysis to examine the association between PPD and child's BMI z-score stratified by the child's age at 1 year and 3 years of age.

RESULTS

The prevalence of PPD at 1 month postpartum (17%) was found to be higher than at 6 months (12%). In multivariable linear regression analysis we observed that children at 3 years who had mothers with PPD at 6 months had, on average, a BMI z-score 0.25 higher than children of mothers who did not have PPD at 6 months (ß coefficient 0.25, 95% CI [0.04 to 0.46], p value 0.02), holding all other covariates constant. Also, initiation of weaning food when child is at six months of age was associated with higher BMI z-score of the child at 3 years after adjusting for all covariates (ß coefficient = 0.18, 95% CI [0.03 to 0.34], p-value < 0.05).

CONCLUSION

The significant association between PPD at 6 months and child's BMI z-score at 3 years of age, in conjunction with birth trends and high prevalence of PPD, can add to the body of evidence that there is need for multiple assessment across the first postpartum year to rule out PPD as early screening and early interventions may benefit both maternal health and child development outcomes. These findings can indicate the need for establishing support systems for care-giving activities for mothers with PPD.

Predicting childhood ADHD-linked symptoms from prenatal and perinatal data in the ABCD cohort

This study investigates the capacity of pre/perinatal factors to predict attention-deficit/hyperactivity disorder (ADHD) symptoms in childhood. It also explores whether predictive accuracy of a pre/perinatal model varies for different groups in the population. We used the ABCD (Adolescent Brain Cognitive Development) cohort from the United States (N = 9975). Pre/perinatal information and the Child Behavior Checklist were reported by the parent when the child was aged 9-10. Forty variables which are generally known by birth were input as potential predictors including maternal substance-use, obstetric complications and child demographics. Elastic net regression with 5-fold validation was performed, and subsequently stratified by sex, race/ethnicity, household income and parental psychopathology. Seventeen pre/perinatal variables were identified as robust predictors of ADHD symptoms in this cohort. The model explained just 8.13% of the variance in ADHD symptoms on average (95% CI = 5.6%-11.5%). Predictive accuracy of the model varied significantly by subgroup, particularly across income groups, and several pre/perinatal factors appeared to be sex-specific. Results suggest we may be able to predict childhood ADHD symptoms with modest accuracy from birth. This study needs to be replicated using prospectively measured pre/perinatal data.

Dose-dependent increase in risk of bleeding and bleeding complications in relation to SSRI use at delivery

INTRODUCTION

Depression during pregnancy is a severe state that increases the risk of suicide, as well as adverse newborn outcomes. Selective serotonin re-uptake inhibitors (SSRIs) are effective for the treatment of depression, but increase the risk of bleeding complications at delivery. Knowledge on the dose dependency of this association is lacking.

METHODS

A hospital-based cohort study of all women who gave birth at Karolinska University Hospital in Stockholm over the 5-year period from 2007 to 2011, with or without SSRI use, was undertaken. In total, 334 women who delivered vaginally and were exposed to SSRIs at delivery were identified. All other women who delivered vaginally formed the control group (n = 31,929). The electronic maternal health records of the 334 SSRI users were scrutinized, and the women were categorized into two groups: moderate (n = 246) or high (n = 88) SSRI dose at delivery. The main outcome was bleeding complications at delivery in relation to SSRI dose.

RESULTS

A dose-dependent increase in the rate of postpartum haemorrhage (≥1000 ml) was found, affecting 8.4 %, 14.6 % and 23.9 % (p ≤ 0.001) of women in the control group, the moderate-dose group and the high-dose group, respectively. In addition, a dose-dependent increase in the rate of postpartum anaemia was found, affecting 7.0 %, 9.3 % and 15.9 % (p = 0.001) of women in the control group, the moderate-dose group and the high-dose group, respectively. Mean blood loss of 406 ml, 483 ml and 482 ml (p ≤ 0.001) was found in the control group, the moderate-dose group and the high-dose group, respectively. Women exposed to SSRIs delivered earlier, but did not have higher prevalence of pre-eclampsia compared with the control group.

CONCLUSIONS

The dose-dependent relationship between SSRIs and bleeding complications may be clinically useful in the management of this vulnerable group of women.

Infant Obesity Prevention Programs for Underrepresented Mothers in a Home Visiting Program: A Qualitative and Community-Engaged Needs Assessment

A qualitative, community-engaged assessment was conducted to identify needs and priorities for infant obesity prevention programs among mothers participating in home visiting programs. Thirty-two stakeholders (i.e., community partners, mothers, home visitors) affiliated with a home visiting program serving low-income families during the prenatal to age three period participated in group level assessment sessions or individual qualitative interviews. Results indicated families face many challenges to obesity prevention particularly in terms of healthy eating. An obesity prevention program can address these challenges by offering realistic feeding options and non-judgmental peer support, improving access to resources, and tailoring program content to individual family needs and preferences. Informational needs, family factors in healthy eating outcomes, and the importance of access and awareness of programs were also noted. To ensure the cultural- and contextual-relevance of infant obesity prevention programs for underserved populations, needs and preferences among community stakeholders and the focal population should be used as a roadmap for intervention development.

Implementing and evaluating group interpersonal therapy for postnatal depression in Lebanon and Kenya-individually randomised superiority trial

BACKGROUND

Depression ranks as the foremost mental health concern among childbearing women. Within low- and middle-income countries (LMICs), between 20 and 25% of women encounter depression during pregnancy or soon after delivery. This condition impacts not only the mothers but also their offspring. Offspring of women suffering from postnatal depression (PND) exhibit suboptimal cognitive development and increased emotional and behavioural issues throughout their growth. This scenario becomes more pronounced in LMICs, where numerous adversities further jeopardise children's developmental progress. Despite antenatal services providing a pivotal platform to address women's mental health needs, PND treatment remains inaccessible in many LMICs. The World Health Organization advocates interpersonal psychotherapy (IPT) for treating depression. While research from high-income countries has established the efficacy of IPT and group-IPT (g-IPT) for PND, its effectiveness within the LMIC context and its potential benefits for child development remain uncharted. This study seeks to gauge the potency of g-IPT for women with PND in two LMICs.

METHODS

This multi-site randomised controlled trial is a continuation of two preceding phases-conceptual mapping and a feasibility study executed in Lebanon and Kenya. Insights gleaned from these phases underpin this comprehensive RCT, which contrasts the efficacy and cost-effectiveness of high-quality standard care (HQ-SC) augmented with g-IPT against HQ-SC in isolation. The trial, characterised as an individually randomised superiority assessment, targets women with postnatal depression in Beirut, Lebanon, and Nairobi, Kenya. It aims to determine if culturally tailored g-IPT, administered within community settings in both countries, outperforms HQ-SC in influencing child developmental outcomes, maternal depression, and the quality of the mother-child bond.

DISCUSSION

The SUMMIT trial, designed with pragmatism, possesses the magnitude to evaluate g-IPT within two LMIC frameworks. It seeks to enlighten policymakers, service commissioners, professionals, and users about g-IPT's potential to alleviate maternal PND and bolster child developmental outcomes in LMICs. Additionally, the trial will generate valuable data on the clinical and economic merits of high-quality standard care.

Which individual, social, and urban factors in early childhood predict psychopathology in later childhood, adolescence and young adulthood? A systematic review

Background

A comprehensive picture is lacking of the impact of early childhood (age 0-5) risk factors on the subsequent development of mental health symptoms.

Objective

In this systematic review, we investigated which individual, social and urban factors, experienced in early childhood, contribute to the development of later anxiety and depression, behavioural problems, and internalising and externalising symptoms in youth.

Methods

Embase, MEDLINE, Scopus, and PsycInfo were searched on the 5th of January 2022. Three additional databases were retrieved from a mega-systematic review source that focused on the identification of both risk and protective indicators for the onset and maintenance of prospective depressive, anxiety and substance use disorders. A total of 46,450 records were identified and screened in ASReview, an AI-aided systematic review tool. We included studies with experimental, quasi-experimental, prospective and longitudinal study designs, while studies that focused on biological and genetical factors, were excluded.

Results

Twenty studies were included. The majority of studies explored individual-level risk factors (N = 16). Eleven studies also explored social risk factors and three studied urban risk factors. We found evidence for early predictors relating to later psychopathology measures (i.e., anxiety and depression, behavioural problems, and internalising and externalising symptoms) in childhood, adolescence and early adulthood. These were: parental psychopathology, exposure to parental physical and verbal violence and social and neighbourhood disadvantage.

Conclusions

Very young children are exposed to a complex mix of risk factors, which operate at different levels and influence children at different time points. The urban environment appears to have an effect on psychopathology but it is understudied compared to individual-level factors. Moreover, we need more research exploring the interaction between individual, social and urban factors.

Mother-infant interaction and infant development in women at risk of postpartum psychosis with and without a postpartum relapse

BACKGROUND

This study aimed to investigate mother-infant interaction and infant development in women at-risk of postpartum psychosis (PP), with and without a postpartum relapse.

METHODS

103 women (and their offspring) were included, 43 at-risk-of-PP because of a diagnosis of bipolar disorder, schizoaffective disorder or previous PP, and 60 with no current/previous mental illness or family history of PP. Of the at-risk women, 18 developed a psychiatric relapse within 4 weeks after delivery (AR-unwell), while 25 remained symptom-free (AR-well). Mother-infant interaction was assessed using the CARE-Index at 8 weeks' and 12 months' postpartum and infant development using the Bayley-III at 12 months' postpartum.

RESULTS

Women at-risk-of-PP as a group, regardless of whether they developed a psychiatric relapse within 4 weeks after delivery, had less synchronous mother-infant interactions and had infants with less optimal cognitive, language, motor and socio-emotional development than healthy controls. In particular, boys of at-risk women had the lowest scores in cognitive, language and motor development and in mother-infant interaction, while girls of the at-risk women had the lowest scores in socio-emotional development. The synchrony in the dyad predicted infant cognitive and language development. There was no evidence for a difference in mother-infant interaction nor in infant development between the AR-unwell and AR-well groups.

CONCLUSIONS

These results suggest that, while there is a lack of evidence that an early postpartum relapse in women at-risk-of-PP could represent a risk for the infant per se, maternal risk for PP may be associated with less optimal mother-infant interaction and infant development.

Pediatrician and parental evaluation of child neurodevelopment at 2 years of age

BACKGROUND

The early identification of infants with a risk for neurodevelopmental disorders in the first few years of life is essential for better developmental outcomes. Screenings should be carried out by combining the family pediatricians' and parents' perspectives, the two fundamental sources of information on children's health. The present study has three aims: (a) to test the feasibility of parent-report instruments to detect warning signs in their children's development; (b) to ascertain whether there is an agreement between the family pediatricians' (FP) clinical judgments of warning signs and the parental perceptions; (c) to determine whether there is a link between parents' distress and child development.

METHODS

Within the NASCITA birth cohort, in addition to the family pediatrician's clinical evaluation with routine tools, the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R) was completed by parents to assess the child's language, social skills, behavior, and sensory areas. Parents were also asked to complete the Parenting Stress Index, Short Form (PSI-SF) to verify the magnitude of stress in the parent-child system. Univariate and multivariate analyses were performed to evaluate the association between child and parental characteristics and the presence of warning signs.

RESULTS

The follow-up assessment was completed for 435 infants: 69 (15.8%) presented warning signs: 43 in the pediatrician's assessment and 36 in the M-CHAT-R (10 in both). A total of 16 children (14 with warning signs) received a diagnosis after a specialist evaluation. Being male (OR 2.46, 95%CI: 1.23-4.91) and having sleep disorders (OR 2.43, 95% CI 1.17-5.04) was associated with a greater likelihood of warning signs in the multivariate analysis, while reading aloud was a protective factor (not exposed versus exposed (OR = 3.14; 95% CI 1.60-6.17). For 73 children (18.4%), at least one parent tested positive for PSI-SF. An increased prevalence of parental distress was observed in children with warning signs (OR 2.36, 95% CI 1.27-4.37).

CONCLUSIONS

Integrating physician and parental perspectives during well-child visits and in clinical practice appears feasible and can improve the identification of children at risk of developmental disorders.

Prevalence of maternal depression and anxiety symptoms and associations with child mental health outcomes in rural Nepal

OBJECTIVES

This study describes the prevalence, associated factors and child mental health outcomes related to symptoms of maternal depression and anxiety within 5 years after childbirth in a rural district in Nepal. This association is not well-understood in rural, community-based settings in low- and middle-income countries (LMIC).

METHODS

A sample of 347 women with children under 5 years was recruited in September 2019 for a cross-sectional study in the rural Saptari district in Nepal. Multivariable logistic regression was used to investigate the association between maternal depressive or anxiety symptoms and children's experience and impact of emotional and behavioural difficulties.

RESULTS

In total, 144 women (41.5%) had moderate or severe depression symptoms and 118 (34%) had anxiety symptoms. Mothers with a lower income were more likely to have anxiety symptoms than the highest income group (OR: 1.8, 95% CI: 1.1-3.0). An association existed between maternal depressive symptoms and the impact of emotional or behavioural difficulties in children (OR: 2.44, 95% CI: 1.02-5.84). In contrast, there was no association between maternal anxiety and child outcomes.

CONCLUSIONS

Our findings suggest that the prevalence of probable maternal anxiety and depression symptoms was relatively high in this rural, low-resourced and community-based setting in Nepal. Maternal depressive symptoms were associated with the degree of impact on children's mental health post-infancy, emphasising the importance of improving maternal mental health in the early years of a child's life.

Longitudinal pathways between maternal depression, parenting behaviors, and early childhood development: a mediation analysis

Maternal depression is a global public health concern with far-reaching impacts on child development, yet our understanding of mechanisms remains incomplete. This study examined whether parenting mediates the association between maternal depression and child outcomes. Participants included 841 rural Pakistani mother-child dyads (50% female). Maternal depression was measured at 12 months postpartum, parenting behaviors (warmth, stimulation, and harsh parenting) were measured at 24 months, and child outcomes (mental health, socioemotional development, and cognitive skills) were measured at 36 months. Maternal depression predicted increased harsh parenting, child mental health difficulties, and child socioemotional concerns; however, there was little evidence for parenting as a mediator between maternal depression and child outcomes. Sex-stratified results are discussed, and findings are situated in context.

Impact of maternal depression on malnutrition treatment outcomes in older children with sickle cell anemia

BACKGROUND

Malnutrition and sickle cell anemia (SCA) result in high childhood mortality rates. Although maternal depression is an established risk factor for malnutrition in younger children, little is known about its impact on treatment response in children with malnutrition. We aimed to determine the relationship, if any, between maternal depression scores and malnutrition treatment outcomes in older children with SCA.

METHODS

We conducted a planned ancillary study to our randomized controlled feasibility trial for managing severe acute malnutrition in children aged 5-12 with SCA in northern Nigeria (NCT03634488). Mothers of participants completed a depression screen using the Patient Health Questionnaire (PHQ-9).We used a multivariable linear regression model to describe the relationship between the baseline maternal PHQ-9 score and the trial participant's final body mass index (BMI) z-score.

RESULTS

Out of 108 mother-child dyads, 101 with maternal baseline PHQ-9 scores were eligible for inclusion in this analysis. At baseline, 25.7% of mothers (26 of 101) screened positive for at least mild depression (PHQ-9 score of 5 or above). The baseline maternal PHQ-9 score was negatively associated with the child's BMI z-score after 12 weeks of malnutrition treatment (β=-0.045, p = 0.041).

CONCLUSIONS

Maternal depressive symptoms has an impact on malnutrition treatment outcomes. Treatment of malnutrition in older children with sickle cell anemia should include screening for maternal depression and, if indicated, appropriate maternal referral for depression evaluation and treatment.

Comparing the effectiveness of mother-focused interventions to that of mother-child focused interventions in improving maternal postpartum depression outcomes: A systematic review

BACKGROUND

Most empirically researched interventions for postpartum depression (PPD) tend to target mothers' depression alone. Harmful effects of PPD on physical and mental health of both mother and child has led researchers to investigate the impact of interventions on PPD and child outcomes together. So far, the evidence is limited regarding how these interventions compare with those focusing only on mothers' depression. This review compares the effectiveness of PPD-improving interventions focusing only on mothers with those focusing on mother and child together.

METHODS

Nine electronic databases were searched. Thirty-seven studies evaluating mother-focused (n = 30) and mother-child focused interventions (n = 7) were included. Under each category, three theoretical approaches-psychological, psychosocial and mixed-were compared using standardized qualitative procedures. The review's primary outcome was maternal PPD.

RESULTS

A higher proportion of mother-focussed interventions [20/30 (66.7%)] brought significant reduction in PPD outcomes as compared to a lower proportion of mother-child focused interventions [4/7 (57.14%)]. Mother-focused mixed approaches [3/3 (100%)] performed better in improving PPD than psychological [16/24 (67%)] or psychosocial approaches [1/3 (33.3%)] alone. Amongst mother-child focused interventions, psychosocial approaches performed well with two-thirds demonstrating positive effects on PPD.

CONCLUSION

The evidence strongly favors mother-focused interventions for improving PPD with mixed interventions being more effective. Psychosocial approaches performed better with PPD once child-related elements were added, and also seemed best for child outcomes. Psychological approaches were most practiced and effective for PPD, irrespective of the intervention's focus. Further trials are needed to unpack intervention components that improve PPD and increase uptake, especially in lower-and middle-income countries.

Postpartum depressive symptoms in women with female genital mutilation in Somalia

OBJECTIVES

This study aimed to identify associated factors for postpartum depression (PPD) among women with female genital mutilation (FGM) in Somalia.

METHODS

This was a cross-sectional study conducted between February and May 2021 in Somalia Mogadishu-Turkey Recep Tayyip Erdogan Training and Research Hospital, Mogadishu, Somalia. Mothers with any known chronic disease, or psychiatric disorders and who refused to participate were excluded from the study. The cutoff point for depression was defined as ≥13 points according to the Edinburgh Postnatal Depression Scale.

RESULTS

Out of 446 postpartum mothers, 267 (59.9%) had increased depressive symptoms in the early postpartum period. PPD scale scores of mothers who were very poor were significantly higher depression scores than their counterparts (p = .002). Education level, place of residence, occupational status, number of children, type of FGM, and the presence of perineal tear did not differ significantly between depressed and non-depressed groups.

CONCLUSIONS

Women with FGM had increased depressive symptoms in the early postpartum period in Somalia. In addition, women who had lower income had higher PPD scores than their counterparts. Further studies are needed to develop a deeper understanding of the relationships between FGM and PPD and its causes.

Epigenome-wide meta-analysis of prenatal maternal stressful life events and newborn DNA methylation

Prenatal maternal stressful life events are associated with adverse neurodevelopmental outcomes in offspring. Biological mechanisms underlying these associations are largely unknown, but DNA methylation likely plays a role. This meta-analysis included twelve non-overlapping cohorts from ten independent longitudinal studies (N = 5,496) within the international Pregnancy and Childhood Epigenetics consortium to examine maternal stressful life events during pregnancy and DNA methylation in cord blood. Children whose mothers reported higher levels of cumulative maternal stressful life events during pregnancy exhibited differential methylation of cg26579032 in ALKBH3. Stressor-specific domains of conflict with family/friends, abuse (physical, sexual, and emotional), and death of a close friend/relative were also associated with differential methylation of CpGs in APTX, MyD88, and both UHRF1 and SDCCAG8, respectively; these genes are implicated in neurodegeneration, immune and cellular functions, regulation of global methylation levels, metabolism, and schizophrenia risk. Thus, differences in DNA methylation at these loci may provide novel insights into potential mechanisms of neurodevelopment in offspring.

Socioeconomic resources moderate the relationship between maternal prenatal obsessive-compulsive symptoms and infant negative affectivity

Perinatal maternal depression, anxiety, and stress are associated with poor infant outcomes. However, no known study has investigated the effects of perinatal maternal obsessive-compulsive symptomatology on infant outcomes while considering important situational factors such as socioeconomic resources. Therefore, we investigated the effects of prenatal and postnatal obsessive-compulsive symptomatology on infant behavioral reactivity, beyond the effects of postnatal depressive symptomatology, at 6 months of age. It was expected that socioeconomic resources would moderate this relationship. We recruited 125 pregnant women from a Health Professional Shortage Area for mental health and primary care in the Midwest United States and interviewed them at approximately 34 weeks gestation and again at 6 months postnatally. They were administered questionnaires at both time points measuring obsessive-compulsive and depressive symptoms. Infant behavioral reactivity was gathered during 6-month follow-up through behavioral observation coding and maternal-report modalities. Maternal-reported infant negative affectivity at 6 months was related to greater severity of maternal postnatal depressive symptomatology, and socioeconomic resources moderated the relationship between maternal prenatal obsessive-compulsive symptoms and maternal-reported infant negative affectivity. However, neither of these relations was statistically significant when infant reactivity was quantified using behavioral observations.

Maternal adverse childhood experiences on child growth and development in rural Pakistan: An observational cohort study

Maternal adverse childhood experiences (ACEs) have significant impacts on the next generation with links to negative birth outcomes, impaired cognitive development, and increased socioemotional problems in children. However, not all types or levels of adversity are similarly deleterious and research from diverse contexts is needed to better understand why and how intergenerational transmission of adversity occurs. We examined the role of maternal ACEs on children's growth, cognitive, and socioemotional development at 36 months postpartum in rural Pakistan. We used data from 877 mother-child dyads in the Bachpan Cohort, a birth cohort study. Maternal ACEs were captured using an adapted version of the ACE-International Questionnaire. Outcomes at 36 months of age included child growth using the WHO growth z-scores, fine motor and receptive language development assessed with the Bayley Scales of Infant and Toddler Development, and socioemotional and behavioral development measured with the Ages and Stages Questionnaire: Socioemotional and Strengths and Difficulties Questionnaire. To estimate the associations between maternal ACEs and child outcomes, we used multivariable generalized linear models with inverse probability weights to account for sampling and loss to follow-up. Over half of mothers in our sample (58%) experienced at least one ACE. Emotional abuse, physical abuse, and emotional neglect were the most commonly reported ACEs. We found null relationships between the number of maternal ACEs and child growth. Maternal ACEs were associated with higher fine motor and receptive language development and worse socioemotional and behavioral outcomes. Maternal ACE domains had similarly varying relationships with child outcomes. Our findings highlight the complexity of intergenerational associations between maternal ACEs and children's growth and development. Further work is necessary to examine these relationships across cultural contexts and identify moderating factors to mitigate potential negative intergenerational effects.

Antenatal depression and adverse birth outcomes among pregnant women living with HIV in Dar es Salaam, Tanzania

BACKGROUND

Women who experience antenatal depression may be at increased risk of adverse birth outcomes. Few studies have examined this association among women living with HIV (WHIV).

METHODS

We conducted a prospective cohort study of 2298 pregnant WHIV on antiretroviral therapy (ART) in Dar es Salaam, Tanzania, who were participants in a randomized trial of vitamin D3 supplementation. Depressive symptoms were assessed at 12-27 weeks gestation using the Hopkins Symptoms Checklist (HSCL-25). Generalized estimating equations to account for twins were used to assess the relative risks of adverse birth outcomes.

RESULTS

Approximately 67 % of the women in our study population reported symptoms consistent with depression. We observed a 4.0 % prevalence of stillbirth and a 25.1 % prevalence of preterm birth. We found that low social support, higher education, and more recent initiation of ART were associated with a greater risk of antenatal depression. There was no association of antenatal depression with risk of fetal loss, stillbirth, low birth weight, birth weight, preterm birth, gestational age at delivery, or small-for-gestational age.

LIMITATIONS

Depression was self-reported and only collected at one timepoint in pregnancy. Our findings may not be generalizable to all WHIV.

CONCLUSIONS

Our findings illustrate the high risk of both depression and adverse birth outcomes among WHIV and underscore the need for interventions to improve their mental health and the health of their infants; however, the relationship between depression and birth outcomes remains unclear. Further research on this topic is merited, particularly examining the chronicity and timing of depression in pregnancy.

Prevalence of depressive disorder in the adult population of Latin America: a systematic review and meta-analysis

Background

Depressive disorder is one of the leading causes of disability worldwide; however its prevalence and association with inequality and crime is poorly characterised in Latin America. This study aimed to: i. systematically review population-based studies of prevalence of ICD/DSM depressive disorder in Latin America, ii. report pooled regional, country, and sex-specific prevalence estimates, and iii. test its association with four country-level development indicators: human development (HDI), income (Gini) and gender inequality (GII), and intentional homicide rate (IHR).

Methods

We conducted a systematic review and meta-analysis of population-based studies reporting primary data on the prevalence of ICD/DSM depressive disorder in Latin America from 1990 to 2023, irrespective of language. We searched PubMed, PsycINFO, Cochrane Library, SciELO (regional database), LILAC (regional database), and available grey literature. Study quality was assessed using JBI's critical appraisal tools. We generated pooled estimates using random-effects meta-analysis; heterogeneity was assessed using the I2 statistic. Meta-regression analyses were used to test associations of depression prevalence with indicators of inequality and human development. The study was registered with PROSPERO (CRD42019143054).

Findings

Using data from 40 studies in Latin America, lifetime, 12-month, and current prevalence of ICD/DSM depressive disorder were calculated at 12.58% (95% CI 11.00%-14.16%); 5.30% (4.55-6.06%), and 3.12% (2.22-4.03), respectively. Heterogeneity was high across lifetime, 12-month, and current prevalence, sex, and countries. 12-month and current prevalence was associated with higher Gini and GII, 12-month prevalence with lower HDI, and current prevalence with higher IHR.

Interpretation

We found a high prevalence of ICD/DSM depressive disorders in Latin America, and a statistically significant association with inequality and development indicators. The high heterogeneity found across prevalence periods and the major gaps in country representation underscore the need to escalate efforts to improve mental health access and research capabilities in Latin America. Systematic, comparable prevalence estimates would inform more effective decision-making in the region.

Maternal depression trajectories in childhood, subsequent maltreatment, and adolescent emotion regulation and self-esteem: the 2004 Pelotas birth cohort

This study aimed to examine the impact of maternal depressive symptoms trajectories on 15-year-old adolescents' self-esteem and emotion regulation and test the mediating role of child maltreatment in this association. The 2004 Pelotas Birth Cohort is an ongoing cohort study originally comprised of 4231 live births in a southern Brazilian city. We examined a subsample of 1949 adolescents at age 15 years. Maternal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale. Trajectories of maternal depression from 3 months until the 11-year follow-up were calculated using a group-based modeling approach. Child maltreatment at age 11 years was measured using the parent-report version of the Parent-Child Conflict Tactics Scale. Adolescent outcomes at age 15 years were assessed by the self-report version of the Rosenberg Self-esteem Scale and the Emotion Regulation Index for Children and Adolescents. Path model analysis was conducted using a structural equation modeling framework in Mplus software. All maternal depression trajectories were negatively associated with offspring self-esteem and emotion regulation compared to the reference group (low depression trajectory). There was a significant indirect effect of maternal depression trajectories on emotion regulation mediated via child maltreatment. No evidence of moderation by sex was found for any pathway. The effects of maternal depression on adolescents' emotion regulation are partly mediated by child maltreatment at age 11.

Multilevel analysis of factors associated with untreated diarrhea among under five children in Ethiopia using Ethiopian demographic and health survey

Diarrhea refers to the abrupt onset of three or more loose or liquid stools per day. It is the second leading cause of death in infants worldwide. It is an endemic disease and continues to be a serious threat to children in Ethiopia. Despite being a condition that may be prevented, diarrhea can have a negative impact on a child's health. Also, studies have not been able to explore the role of socio-economic characteristics in hindering the treatment. Therefore, this study aimed to explore socio-economic factors that influence treatment of childhood diarrhea. Secondary data analysis was conducted based on the demographic and health surveys data conducted in Ethiopia. A total weighted sample of 1227 under-five children was included for this study. Mixed-effect binary logistic regression analysis was done to identify associated factors of untreated diarrhea. Adjusted Odds Ratio with 95% CI was used to declare the strength and significance of the association. Prevalence of untreated diarrhea among under five children in Ethiopia was 57.32% (95% CI 54.52-60.06%). In the mixed-effect analysis; Children aged 6-11, 12-23, and 24-35 (AOR 0.384, 95% CI 0.187-0.789), 71% (AOR 0.29, 95% CI 0.149-0.596), and 51% (AOR 0.49, 95% CI 0.238-0.995). Children from family number six and above (AOR 1.635, 95% CI 1.102-2.426). Children from middle wealth of family (AOR 1.886, 95% CI 1.170-3.3040). Children from a community with high level of uneducated (AOR 2.78, 95% CI 1.065-3.442) were significantly associated with untreated diarrhea. The prevalence of untreated diarrhea among under-five children in Ethiopia is high. Age of child, family number, household wealth, and community-level educational status were significantly associated with untreated diarrhea among under-five children in Ethiopia. Hence, increasing community educational status, boosting the economic status of the community, and family planning for the community should get due attention.

Maternal adverse childhood experiences, child mental health, and the mediating effect of maternal depression: A cross-sectional, population-based study in rural, southwestern Uganda

OBJECTIVES

This study aimed to examine the intergenerational effects of maternal adverse childhood experiences (ACEs) and child mental health outcomes in rural Uganda, as well as the potentially mediating role of maternal depression in this pathway. Additionally, we sought to test the extent to which maternal social group membership attenuated the mediating effect of maternal depression on child mental health.

METHODS

Data come from a population-based cohort of families living in the Nyakabare Parish, a rural district in southwestern Uganda. Between 2016 and 2018, mothers completed surveys about childhood adversity, depressive symptoms, social group membership, and their children's mental health. Survey data were analyzed using causal mediation and moderated-mediation analysis.

RESULTS

Among 218 mother-child pairs, 61 mothers (28%) and 47 children (22%) showed symptoms meeting cutoffs for clinically significant psychological distress. In multivariable linear regression models, maternal ACEs had a statistically significant association with severity of child conduct problems, peer problems, and total child difficulty scores. Maternal depression mediated the relationship between maternal ACEs and conduct problems, peer problems, and total difficulty, but this mediating effect was not moderated by maternal group membership.

CONCLUSIONS

Maternal depression may act as a potential mechanism linking maternal childhood adversity with poor child mental health in the next generation. Within a context of elevated rates of psychiatric morbidity, high prevalence of childhood adversity, and limited healthcare and economic infrastructures across Uganda, these results emphasize the prioritization of social services and mental health resources for rural Ugandan families.

Association between depressive symptoms of mothers and eating behaviors of school-going children in Urban Bangladesh: A cross-sectional study

OBJECTIVE

This study aimed to investigate the association between depressive symptoms among mothers and the eating behaviors of their school-going children in Urban Bangladesh.

MATERIALS AND METHODS

This analytical cross-sectional study was conducted in the context of the urban area of Bangladesh. A multistage sampling technique was applied to select 324 children's mothers in Dhaka City. Data were collected from both city corporation settings in Dhaka, Bangladesh. Semi-structured questionnaires were used in this study. We estimated the depressive symptoms among mothers using the Zung Self-Rating Depression Scale. We examined the association of mothers of school-going children's socio-demographic variables and eating behaviors of school-going children with their mother's depression by using chi-square and evaluating the impact of these variables on mothers' depression through univariate and multivariate binary logistic regression.

RESULTS

In our study, 57.7% of the mothers of school-going children had depressive symptoms, and 42.3% had no depressive symptoms. The study explored that consuming fewer vegetables (AOR = 0.237, 95% CI: 0.099-0.569), taking fewer fruits (AOR = 0.177, 95% CI: 0.093-0.337), and interestingly, taking fast food less than 4 days per week (AOR = 3.024, 95% CI: 1.517-6.031) were significantly associated with mothers' depressive symptoms.

CONCLUSION

Mothers with depressive symptoms of school-going children in Dhaka city are alarmingly high as a grave concern. The eating behaviors of children are associated with their mothers' depressive symptoms. With an aim to build rigorous awareness on depression and child's healthy eating behaviors, it is imperative to arrange health education and awareness related programs.

Chronic Stress That Changed Intestinal Permeability and Induced Inflammation Was Restored by Estrogen

Chronic psychological stress affects the health of humans and animals (especially females or pregnant bodies). In this study, a stress-induced model was established by placing eight-week-old female and pregnant mice in centrifuge tubes for 4 h to determine whether chronic stress affects the intestinal mucosal barrier and microbiota composition of pregnant mice. Compared with the control group, we found that norepinephrine (NE), corticosterone (CORT), and estradiol (E2) in plasma increased significantly in the stress group. We then observed a decreased down-regulation of anti-inflammatory cytokines and up-regulation of pro-inflammatory cytokines, which resulted in colonic mucosal injury, including a reduced number of goblet cells, proliferating cell nuclear antigen-positive cells, caspase-3, and expression of tight junction mRNA and protein. Moreover, the diversity and richness of the colonic microbiota decreased in pregnant mice. Bacteroidetes decreased, and pernicious bacteria were markedly increased. At last, we found E2 protects the intestinal epithelial cells after H2O2 treatment. Results suggested that 25 pg/mL E2 provides better protection for intestinal barrier after chronic stress, which greatly affected the intestinal mucosal barrier and altered the colonic microbiota composition.

Parenting stress and Chinese preschoolers' approaches to learning: a moderated mediation model of authoritative parenting and household residency

According to the family stress model, this study examined the relationship between parenting stress and preschoolers' approaches to learning (ATL) in China, as well as the mediating effect of authoritative parenting and the moderating effect of household residency (migrant and native). A survey of 5,047 preschoolers' parents (2,186 natives and 2,861 migrants) supports the proposed moderated mediation model. The results showed that after controlling for gender and age, parenting stress affected preschoolers' development of ATL negatively. Authoritative parenting mediates the relationship between parenting stress and preschoolers' ATL. Further, household residency moderated the relationship between authoritative parenting and preschoolers' ATL. The findings of this study suggest that high levels of parenting stress are detrimental to the development of preschoolers' ATL. And parents with low parenting stress are more likely to adopt authoritative parenting, which in turn fosters preschoolers' ATL. In addition, native families' authoritative parenting style are more conducive to fostering preschoolers' ATL than migrant families. Finally, this study contributes to previous research by examining the mechanisms of parenting stress on preschoolers' ATL and provides support for the extension of the family stress model. Importantly, it also informs efforts to improve ATL among preschoolers in Chinese migrant and native families.

Course of depression during the first 2 years postpartum among Brazilian women enrolled in a conditional cash transfer program

BACKGROUND

Women living in low- and middle-income countries are more exposed to known risk factors for depression occurrence and persistency over time.

AIM

Our aim was to investigate the course of depression in the first 2 years postpartum among Brazilian women enrolled in a cash transfer program.

METHOD

Longitudinal analysis of baseline (T0; mean 3.7 months postpartum) and first follow-up data (T1; mean 18.6 months postpartum) from a trial to assess the impact of a child development promotion program in 30 municipalities from six Brazilian states. The program does not include any interventions against maternal depression. The Edinburgh Postnatal Depression Scale (EPDS) at cutoff ⩾10 was applied. Women were categorized into four groups based on EPDS at T0 and T1: absence of depression, persistence, discontinuity, or emergence pattern. Adjusted Poisson regressions were run using a multilevel hierarchical model.

RESULTS

Two thousand eight hundred sixty-three women were assessed. Prevalence of depression was 26.4% [24.8, 28.1] at T0 and 24.4% [22.8, 26.0] at T1. Persistence, discontinuation, and emergence were found in 14.1% [11.3, 17.6%], 12.8% [11.4, 14.3%], and 10.2% [8.0, 13.0], respectively. In adjusted analyses, the persistence pattern was directly associated with parity and inversely associated with schooling of the woman and of the child's father. Living with husband/partner and support from the child's father and family members during pregnancy were protective against persistence. The discontinuity and the emergence patterns were not associated with any of the exposure variables.

CONCLUSIONS

Depressive symptoms were highly prevalent during the first 2 years postpartum. About half of the women with depression at T1 were persistent cases that could have been detected earlier. Screening for maternal depression should be an essential component in every encounter of women with health professionals in primary health care settings.

Serotonin transporter (5-HTT) gene network moderates the impact of prenatal maternal adversity on orbitofrontal cortical thickness in middle childhood

In utero, the developing brain is highly susceptible to the environment. For example, adverse maternal experiences during the prenatal period are associated with outcomes such as altered neurodevelopment and emotion dysregulation. Yet, the underlying biological mechanisms remain unclear. Here, we investigate whether the function of a network of genes co-expressed with the serotonin transporter in the amygdala moderates the impact of prenatal maternal adversity on the structure of the orbitofrontal cortex (OFC) in middle childhood and/or the degree of temperamental inhibition exhibited in toddlerhood. T1-weighted structural MRI scans were acquired from children aged 6-12 years. A cumulative maternal adversity score was used to conceptualize prenatal adversity and a co-expression based polygenic risk score (ePRS) was generated. Behavioural inhibition at 18 months was assessed using the Early Childhood Behaviour Questionnaire (ECBQ). Our results indicate that in the presence of a low functioning serotonin transporter gene network in the amygdala, higher levels of prenatal adversity are associated with greater right OFC thickness at 6-12 years old. The interaction also predicts temperamental inhibition at 18 months. Ultimately, we identified important biological processes and structural modifications that may underlie the link between early adversity and future deviations in cognitive, behavioural, and emotional development.

Developmental Cascades Link Maternal-Newborn Skin-to-Skin Contact with Young Adults' Psychological Symptoms, Oxytocin, and Immunity; Charting Mechanisms of Developmental Continuity from Birth to Adulthood

Premature birth disrupts the continuity of maternal-newborn bodily contact, which underpins the development of physiological and behavioral support systems. Utilizing a unique cohort of mother-preterm dyads who received skin-to-skin contact (Kangaroo Care, KC) versus controls, and following them to adulthood, we examined how a touch-based neonatal intervention impacts three adult outcomes; anxiety/depressive symptoms, oxytocin, and secretory immunoglobulin A (s-IgA), a biomarker of the immune system. Consistent with dynamic systems' theory, we found that links from KC to adult outcomes were indirect, mediated by its effects on maternal mood, child attention and executive functions, and mother-child synchrony across development. These improvements shaped adult outcomes via three mechanisms; (a) "sensitive periods", where the infancy improvement directly links with an outcome, for instance, infant attention linked with higher oxytocin and lower s-IgA; (b) "step-by-step continuity", where the infancy improvement triggers iterative changes across development, gradually shaping an outcome; for instance, mother-infant synchrony was stable across development and predicted lower anxiety/depressive symptoms; and (c) "inclusive mutual-influences", describing cross-time associations between maternal, child, and dyadic factors; for instance, from maternal mood to child executive functions and back. Findings highlight the long-term impact of a birth intervention across development and provide valuable insights on the mechanisms of "developmental continuity", among the key topics in developmental research.

Effect of biological, psychological, and social factors on maternal depressive symptoms in late pregnancy: a cross-sectional study

Introduction

Depression commonly occurs during pregnancy and has become a major public health concern. Depression not only affects the individual but also causes adverse consequences for families and children. However, little is known regarding the depression status and its influencing factors in women during late pregnancy in China. This study aimed to assess the prevalence of maternal depressive symptoms in late pregnancy during the coronavirus disease 2019 (COVID-19) pandemic and further explore the effect of biological, psychological, and social factors on depressive symptoms.

Methods

An institution-based cross-sectional survey was conducted among eligible women in the late pregnancy stage and underwent prenatal examination at Lianyungang Maternal and Child Health Hospital in Jiangsu Province, Eastern China from December 2022 to February 2023. Data regarding depressive symptoms and biological, psychological, and social factors of the pregnant women were collected via a structured questionnaire. Chi-square test, Fisher's exact tests, and binary logistics regression were used to analyze the data.

Results

In total, 535 women in the late pregnancy stage were included in this study, 75 (14.0%) of whom exhibited depressive symptoms. A binary logistic regression analysis revealed that pregnant women who were multiparous (OR: 2.420, 95% CI: 1.188-4.932) and had moderate or severe insomnia symptoms (OR: 4.641, 95% CI: 1.787-12.057), anxiety (OR: 8.879, 95% CI: 4.387-17.971), high fear of COVID-19 (OR: 2.555, 95% CI: 1.255-5.199), moderate or severe family dysfunction (OR: 2.256, 95% CI: 1.141-4.461), and poor social support (OR: 2.580, 95% CI: 1.050-6.337) tended to show depressive symptoms. Conversely, pregnant women who received regular prenatal care (OR: 0.481, 95% CI: 0.243-0.951) and had good drinking water quality at home (OR: 0.493, 95% CI: 0.247-0.984) were more likely to avoid developing depressive symptoms.

Conclusion

This study found that the prevalence of maternal depressive symptoms during late pregnancy was high and had multiple influencing factors. Thus, screening for depressive symptoms in women in the late pregnancy stage and providing special intervention programs are necessary, especially for those with risk factors.

Maternal-infant interaction quality is associated with child NR3C1 CpG site methylation at 7 years of age

OBJECTIVE

Infancy is both a critical window for hypothalamic-pituitary-adrenal (HPA) axis development, and a sensitive period for social-emotional influences. We hypothesized that the social-emotional quality of maternal-infant interactions are associated with methylation of HPA-axis gene NR3C1 later in childhood.

METHODS

Using a subsample of 114 mother-infant pairs from the Avon Longitudinal Study of Parents and Children (ALSPAC), linear regression models were created to predict variance in methylation of seven selected CpG sites from NR3C1 in whole blood at age 7 years, including the main predictor variable of the first principal component score of observed maternal-infant interaction quality (derived from the Thorpe Interaction Measure at 12 months of age) and covariates of cell-type proportion, maternal financial difficulties and marital status at 8 months postnatal, child birthweight, and sex.

RESULTS

CpG site cg27122725 methylation was negatively associated with warmer, more positive maternal interaction with her infant (β = 0.19, p = .02, q = 0.13). In sensitivity analyses, the second highest quartile of maternal behavior (neutral, hesitant behavior) was positively associated with cg12466613 methylation. The other five CpG sites were not significantly associated with maternal-infant interaction quality.

CONCLUSIONS

Narrow individual variation of maternal interaction with her infant is associated with childhood methylation of two CpG sites on NR3C1 that may be particularly sensitive to environmental influences. Infancy may be a sensitive period for even small influences from the social-emotional environment on the epigenetic determinants of HPA-axis function.

Effectiveness of digital psychological interventions in reducing perinatal depression: a systematic review of meta-analyses

Digital psychological interventions have been widely used clinically in recent years, but the methodological quality and quality of evidence of related studies are unclear, thus interfering with the translation of practice outcomes and the application of clinical decisions. We searched for meta-analyses of randomized controlled trials in the PubMed, Web of Science, Embase, Cochrane Library, JBI Database, CINAHL, and PsycINFO databases as well as some databases containing gray literature up to 27 April 2022 using a combination of keywords. After two researchers independently screened and extracted data from the literature, the methodological quality of the included literature was evaluated by the AMSTAR 2 scale, and the evidence quality of the outcome index was graded by the Grading of Recommendations, Assessment, Development, and Evaluation system. A total of 12 meta-analyses reporting the positive impact of digital psychological interventions in the prevention and/or treatment of depressive symptoms in perinatal women were included, but the methodological quality and evidence level of the included studies were low. Digital psychological interventions are effective in reducing perinatal depression, but the methodological quality and reliability of outcome indicators are mostly low. Improving study designs, using higher-quality clinical evidence, conducting systematic evaluation studies strictly following the procedures, and standardizing the reporting of study results are recommended.

Self-objectification during the perinatal period: The role of body surveillance in maternal and infant wellbeing

Pregnancy represents a unique time during which women's bodies undergo significant physical changes (e.g., expanding belly, larger breasts, weight gain) that can elicit increased objectification. Experiences of objectification set the stage for women to view themselves as sexual objects (i.e., self-objectification) and is associated with adverse mental health outcomes. Although women may experience heightened self-objectification and behavioral consequences (such as body surveillance) due to the objectification of pregnant bodies in Western cultures, there are remarkably few studies examining objectification theory among women during the perinatal period. The present study investigated the impact of body surveillance, a consequence of self-objectification, on maternal mental health, mother-infant bonding, and infant socioemotional outcomes in a sample of 159 women navigating pregnancy and postpartum. Utilizing a serial mediation model, we found that mothers who endorsed higher levels of body surveillance during pregnancy reported more depressive symptoms and body dissatisfaction, which were associated with greater impairments in mother-infant bonding following childbirth and more infant socioemotional dysfunction at 1-year postpartum. Maternal prenatal depressive symptoms emerged as a unique mechanism through which body surveillance predicted bonding impairments and subsequent infant outcomes. Results highlight the critical need for early intervention efforts that not only target general depression, but also promote body functionality and acceptance over the Western "thin ideal" of attractiveness among expecting mothers.

An Integrated Mother-Child Intervention on Child Development and Maternal Mental Health

OBJECTIVES

To evaluate an integrated, low-cost, facility-based group intervention designed to promote child care, boost maternal mental-wellbeing, reduce harsh discipline, and improve children's health, nutrition, and early development.

METHODS

In Dhaka, 30 neighborhood clusters of a low-income urban community were randomized to intervention or control groups. Mothers with children between 6 and 24 months (n = 300) who self-reported negative discipline were identified and enrolled. A 1-year group intervention included integration of responsive caregiving, nutritional supplementation, caregivers' mental health, child protection, and health advice. Child outcomes were cognition (primary) and language, motor and behavioral development, growth, and hemoglobin and iron status (secondary). Maternal outcomes were depressive symptoms, self-esteem, negative discipline, and child care knowledge and practices.

RESULTS

Overall, 222 (74%) mother-child dyads participated in the 1-year follow-up. Intervention and control groups differed on wealth, with no other significant differences. The intervention resulted in a 0.75 SD effect on cognition, 0.77 SD on language, 0.41 SD on motor, and 0.43 to 0.66 SDs on behavior during testing (emotion, cooperation, and vocalization) in the intervention arm. Mothers in the intervention group had fewer depressive symptoms (effect size: -0.72 SD), higher self-esteem (0.62 SD), better child care knowledge (2.02 SD), fewer harsh discipline practices (0.25 SD), and better home stimulation (0.73 SD). The intervention showed no effect on child growth or hemoglobin, but significantly improved serum iron status (-0.36 SD).

CONCLUSIONS

A comprehensive intervention, delivered through group sessions in health facilities, was effective in promoting child development and reducing maternal depressive symptoms among mothers who reported using negative or harsh discipline.

Self-objectification during the perinatal period: The role of body surveillance in maternal and infant wellbeing

Pregnancy represents a unique time during which women's bodies undergo significant physical changes (e.g., expanding belly, larger breasts, weight gain) that can elicit increased objectification.

The feasibility and acceptability of Project POWER: a mindfulness-infused, cognitive-behavioral group intervention to address mental and sexual health needs of young pregnant women in Liberia

BACKGROUND

Following 14 years of civil war in Liberia, war exposure, gender-based violence, and extreme poverty have been identified as key challenges affecting the mental and sexual health of young pregnant women and the health of their unborn children. Despite ongoing efforts to rebuild the country's healthcare infrastructure, empirical and culturally tailored interventions to address the consequences of war are severely limited. To address these concerns, we developed Project POWER (Progressing Our Well-being, Emotions, and Relationships), a mindfulness-infused, cognitive-behavioral intervention for young adult pregnant women. This study sought to 1) assess the feasibility and acceptability of POWER and 2) determine the preliminary efficacy of POWER for improving mental and sexual health outcomes among Liberian war-exposed young adult pregnant women.

METHODS

Eighty-seven women aged 18-25 were recruited from three catchment areas in Monrovia, Liberia to participate in a two-condition, pre-post design quasi-experimental pilot trial. Participants were allocated to the intervention (POWER) or the control condition (a health education program) based on where they resided relative to the catchment areas. Each condition completed a ten-session program delivered over 5-weeks. Feasibility and acceptability of POWER were examined using program logs (e.g., the number of participants screened and enrolled, facilitator satisfaction, etc.) and data from an end-of-program exit interview. The preliminary efficacy of POWER on mental and sexual health outcomes was assessed using repeated measures ANOVA with time and condition as factors.

RESULTS

Analyses provided preliminary support for the feasibility and acceptability of POWER. Participants attended an average of 8.99 sessions out of 10 and practiced material outside the sessions at least 2.77 times per week. Women in both conditions showed significant reductions in the level of prenatal distress (baseline, M = 16.84, 3-month assessment, M = 12.24), severity of post-traumatic stress disorder (PTSD) symptoms (baseline, M = 11.97, 3-month assessment, M = 9.79),), and the number of transactional sexual behaviors (baseline, M = 1.37, 3-month assessment, M = .94) over time. Participants who received POWER showed significant reductions in the frequency of depressive symptoms (baseline, M = 5.09, 3-month assessment, M = 2.63) over women in the control condition.

CONCLUSIONS

Findings suggest that POWER may be a feasible and acceptable intervention to promote mental and sexual health for young adult pregnant women in Liberia. However, fully powered clinical trials are still needed to determine the efficacy and effectiveness of POWER before recommending its use on a larger scale in Liberia.

Prevalence of Perinatal Depression in Low- and Middle-Income Countries: A Systematic Review and Meta-analysis

Importance

Women who experience depression during or within a year of pregnancy are at increased risk of morbidity and mortality. Although those living in low- and middle-income countries are thought to be at increased risk of perinatal depression, the true prevalence remains unclear.

Objective

To determine the prevalence of depression among individuals living in low- and middle-income countries during pregnancy and up 1 year post partum.

Data Sources

MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, and the Cochrane Library were searched from database inception until April 15, 2021.

Study Selection

Studies were included that reported the prevalence of depression using a validated method during pregnancy or up to 12 months post partum in countries defined by the World Bank as low, lower-middle, and upper-middle income.

Data Extraction and Synthesis

This study followed Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Two reviewers independently assessed study eligibility, extracted data, and assessed studies for bias. Prevalence estimates were calculated using a random-effects meta-analysis model. Subgroup analyses were performed among women who were considered at increased risk of developing perinatal depression.

Main Outcomes and Measures

Point prevalence of perinatal depression was the main outcome measured as percentage point estimates with corresponding 95% CIs.

Results

The search identified 8106 studies, of which data were extracted from 589 eligible studies reporting outcomes of 616 708 women from 51 countries. The pooled prevalence of perinatal depression across all studies was 24.7% (95% CI, 23.7%-25.6%). The prevalence of perinatal depression varied slightly by country income status. The highest prevalence was found in lower-middle-income countries, with a pooled prevalence of 25.5% (95% CI, 23.8%-27.1%; 197 studies from 23 countries including 212 103 individuals). In upper-middle-income countries, the pooled prevalence was 24.7% (95% CI, 23.6%-25.9%; 344 studies from 21 countries including 364 103 individuals) and in low-income countries, the pooled prevalence was 20.7% (95% CI, 18.4%-23.0%; 50 studies from 7 countries including 40 502 individuals). The East Asia and the Pacific region had the lowest prevalence of perinatal depression at 21.4% (95% CI, 19.8%-23.1%) and was significantly increased in the Middle East and North Africa at 31.5% (95% CI, 26.9%-36.2%; between-group comparison: P < .001). In subgroup analyses, the highest prevalence of perinatal depression was found among women who experienced intimate partner violence, at 38.9% (95% CI, 34.1%-43.6%). revalence of depression was also high among women with HIV (35.1% [95% CI, 29.6%-40.6%]) and those who had experienced a natural disaster (34.8% [95% CI, 29.4%-40.2%]).

Conclusions and Relevance

This meta-analysis found that depression was common in low- and middle-income countries, affecting 1 in 4 perinatal women. Accurate estimates of the prevalence of perinatal depression in low- and middle-income countries are essential in informing policy, allocating scarce resources, and directing further research to improve outcomes for women, infants, and families.

Depression in mothers at childhood: Direct and indirect association with problematic gaming in late adolescence/young adulthood

OBJECTIVES

Little is known about the relationship between depression in mothers and problematic gaming in their children. Therefore, we aimed to investigate the potential role of mothers' depression in childhood as a risk factor for problematic gaming in their offspring in late adolescence/young adulthood.

METHODS

We assessed data from 1557 participants on three waves (T0 collected in 2010/2011, T1 in 2013/2014, and T2 in 2018/2019) of a large Brazilian school-based cohort. Mother's depression at T0 was tested as a predictor of problematic gaming at T2 in a logistic regression model. In mediation analyses, we individually assessed internalizing or externalizing disorders at T1 as mediators in this association, with participants' sex being tested as a moderator in both models. Inverse probability weights were used to account for sample attrition at T2. All models were adjusted for maternal and participant-related covariates.

RESULTS

Mother's depression at T0 was significantly associated with problematic gaming at T2 (OR = 2.09, p < 0.001) even after adjusting for multiple confounding factors. The presence of any internalizing disorder at T1 was a partial mediator of this relationship, accounting for 8.18% (p = 0.032) of the total effect, while the presence of any externalizing disorder at T1 was not a significant mediator. Participants' sex was not a significant moderator in mediation models.

CONCLUSIONS

These findings suggest mother's depression in childhood as a risk factor for problematic gaming in later developmental stages, which may be partially mediated by internalizing psychopathology.

Racial disparities in EEG research and their implications for our understanding of the maternal brain

Racial disparities in maternal health are alarming and persistent. Use of electroencephalography (EEG) and event-related potentials (ERPs) to understand the maternal brain can improve our knowledge of maternal health by providing insight into mechanisms underlying maternal well-being, including implications for child development. However, systematic racial bias exists in EEG methodology-particularly for Black individuals-and in psychological and health research broadly. This paper discusses these biases in the context of EEG/ERP research on the maternal brain. First, we assess the racial/ethnic diversity of existing ERP studies of maternal neural responding to infant/child emotional expressions, using papers from a recent meta-analysis, finding that the majority of mothers represented in this research are of White/European ancestry and that the racially and ethnically diverse samples that are present are limited in terms of geography. Therefore, our current knowledge base in this area may be biased and not generalizable across racially diverse mothers. We outline factors underlying this problem, beginning with the racial bias in EEG equipment that systematically excludes individuals of African descent, and also considering factors specific to research with mothers. Finally, we highlight recent innovations to EEG hardware to better accommodate diverse hairstyles and textures, and other important steps to increase racial and ethnic representativeness in EEG/ERP research with mothers. We urge EEG/ERP researchers who study the maternal brain-including our own research group-to take action to increase racial diversity so that this research area can confidently inform understanding of maternal health and contribute to minimizing maternal health disparities.

Intimate Partner Violence and Children: Essentials for the Pediatric Nurse Practitioner

Intimate partner violence (IPV) is a public health problem of epidemic proportions. IPV often starts early in adolescence and continues throughout an individual's lifespan. IPV is defined as abuse or aggression occurring in the context of a romantic relationship that is perpetrated by a current or former partner. IPV victims often experience severe psychological trauma, physical injury, and even death. The direct recipient of the violence is often not the only individual impacted. Children are often peripheral victims of IPV. It is vital that pediatric health care providers, including pediatric nurse practitioners, recognize that IPV is indeed a pediatric health care crisis requiring strategies for both identification and intervention. This continuing education article will discuss IPV and its impact on children from conception to adolescence while exploring implications for practice.

Effect of the mHealth-supported Healthy Future programme delivered by community health workers on maternal and child health in rural China: study protocol for a cluster randomised controlled trial

INTRODUCTION

Millions of young rural children in China still suffer from poor health and malnutrition, partly due to a lack of knowledge about optimal perinatal and child care among rural mothers and caregivers. Meanwhile, there is an urgent need to improve maternal mental health in rural communities. Comprehensive home visiting programmes delivered by community health workers (CHWs) can bridge the caregiver knowledge gap and improve child health and maternal well-being in low-resource settings, but the effectiveness of this approach is unknown in rural China. Additionally, grandmothers play important roles in child care and family decision-making in rural China, suggesting the importance of engaging multiple caregivers in interventions. The Healthy Future programme seeks to improve child health and maternal well-being by developing a staged-based curriculum that CHWs deliver to mothers and caregivers of young children through home visits with the assistance of a tablet-based mHealth system. This protocol describes the design and evaluation plan for this programme.

METHODS AND ANALYSIS

We designed a cluster-randomised controlled trial among 119 rural townships in four nationally designated poverty counties in Southwestern China. We will compare the outcomes between three arms: one standard arm with only primary caregivers participating in the intervention, one encouragement arm engaging primary and secondary caregivers and one control arm with no intervention. Families with pregnant women or infants under 6 months of age are invited to enrol in the 12-month study. Primary outcomes include children's haemoglobin levels, exclusive breastfeeding rates and dietary diversity in complementary feeding. Secondary outcomes include a combination of health, behavioural and intermediate outcomes.

ETHICS AND DISSEMINATION

Ethical approval has been provided by Stanford University, Sichuan University and the University of Nevada, Reno. Trial findings will be disseminated through national and international peer-reviewed publications and conferences.

Women's quality of life and mental health in the first year after birth: Associated factors and effects of antenatal preventive measures among mothers in the ELFE cohort

BACKGROUND

During the perinatal period, women's perceived quality of life (QOL) may be altered due to physiological, psychological, and bodily changes, as well as changes in family functioning.

OBJECTIVES

to explore in a sample of women from the general population, the associations between physical and mental QOL at 1 year post-partum and i) pregnancy social support, demographic, socioeconomic, medical and child health-related factors, paternal and maternal psychological characteristics at 2 months and 1 year post-partum, ii) antenatal preventive measures (early prenatal interview/antenatal classes).

METHODS

We used data from the "French Longitudinal Study since Childhood" (ELFE), a representative cohort of children and their parents followed from birth to adulthood. Data were collected from mothers in the maternity ward, at 2 months and 1-year post-partum. QOL was assessed using the SF12 physical (PCS-12) and mental (MCS-12) subscales.

RESULTS

Women with both low PCS-12 and MCS-12 scores were more likely to have high maternal age and to experience psychological difficulties during pregnancy. They also had more frequent PNDS, quarrels with insults within the couple, low sleep time at 2 months postpartum, and more frequently received psychological, social and child caregiver support, and were more often housewives or students at 1-year post-partum. Others factors are specific for low PCS-12 or MCS-12. There was no association with antenatal preventive measure and QOL at 1-year post-partum.

CONCLUSION

Factors influencing maternal QOL are multiple and multidimensional and can mostly be identified during the ante or early postnatal period. A graduated and coordinated preventive and curative pathway would improve women's health. An ecosystemic approach to pregnancy and the perinatal period could help preventing the negative effects of environment on mothers and thus infants during the "1000-day period".

Physical exercise interventions for perinatal depression symptoms in women: A systematic review and meta-analysis

Background

The previous meta-analysis indicated that physical exercise could play a crucially therapeutic role in reducing perinatal depression symptoms in women. However, the efficacy varies across different exercise types, forms, intensities, and duration.

Aim

The purpose of this study was to review and evaluate the effects of different types, forms, intensities, and duration of exercise for improving perinatal depressive symptoms.

Design

A systematic review and meta-analysis.

Methods

Randomized controlled trials until December 2021 were searched from seven databases, including PubMed, EMBASE, Medline, CINAHL, Web of Science, Cochrane Library, and PsycINFO. The risk of bias in eligible trials was evaluated using the Cochrane Risk of Bias tool. When high heterogeneity was tested, we used random-effects models. A funnel plot was used to assess the publication bias. This review was performed under the PRISMA guidelines, Consensus on Exercise Reporting (CERT) checklist and Cochrane Handbook. The certainty of the body of evidence was assessed using the GRADE method.

Results

Of 1,573 records, 20 trials were identified in this study. The results of this review revealed that women with perinatal depression symptoms gained benefits from physical exercise [OR = 0.62, 95% CI (0.45, 0.86), P = 0.004; MD = -0.57, 95% CI (-0.83, -0.30), P < 0.0001]. Type of walking [SMD = -1.06, 95% CI (-1.92, -0.19), P < 0.00001], form of "Individual + group-based"exercise [SMD = -0.91, 95% CI (-0.80, -0.03), P = 0.04], intensity of ≥150 min per week [SMD = -0.84, 95% CI (-1.53, -0.15), P = 0.02], and ≥12 weeks duration [SMD = -0.53, 95% CI (-0.75, -0.31), P < 0.00001] seemed to generate more prominent improvement on perinatal depression symptoms.

Conclusion

Physical exercise showed a significant effect on reducing perinatal depressive symptoms. This meta-analysis provides an important update on exercise's efficacy in treating perinatal depression. Further higher quality and large-scale trials are needed to substantiate our findings.

Systematic mapping on availability, extent and distribution of mental health research in Malawi

Background

Mental health research is essential in the implementation of evidence-based interventions. This can be impeded by unavailability or limited access to local evidence in low- and middle-income countries (LMICs) such as Malawi.

Aim

The aim of this systematic mapping was to describe the availability, extent and distribution of mental health research conducted in Malawi.

Setting

The study was conducted at Kamuzu University of Health Sciences in Malawi.

Methods

A systematic search of four electronic databases from inception to September 2021 was carried out. All published and unpublished mental health studies in all languages were eligible for inclusion. Studies were screened against inclusion and exclusion criteria, and data were extracted, analysed and presented in tables and as a narrative synthesis.

Results

Cross-sectional studies (33.6%, n = 76) were found to be the most common study design for mental health research in Malawi. More studies were conducted on women (21.2%, n = 48) compared to men (1.3%, n = 3). Mental health research was concentrated in the southern region of the country (44.8%, n = 120) and in the three cities of Lilongwe (17.9%, n = 48), Blantyre (16.4%, n = 44) and Zomba (9.0%, n = 24).

Conclusion

This systematic mapping suggests that there are few studies on mental health in Malawi which are not equally distributed across the country. There is a pressing need to conduct more mental health research using robust designs across disciplines.

Contribution

Research on mental health is urgently needed to produce culturally acceptable data in Malawi.

Family environment characteristics and sleep duration in children: Maternal mental health as a mediator

BACKGROUND

Family environment is a key factor affecting children's health. However, little is known about whether and how the family environment affects sleep duration in children. This study investigated the effects of both physical and social characteristics of the family environment on sleep duration in children and determined whether these associations were mediated by maternal mental health.

METHODS

Data were obtained from the Taiwan Birth Cohort Study. A total of 19,400 children who completed 6-month, 18-month, 3-year, 5.5-year, and 8-year surveys were analyzed. The physical family environment characteristics were household crowding and housing quality. Family functioning was used as an indicator of family social environment. Multiple linear regression and path analysis were performed to test the hypotheses.

RESULTS

The children living in crowded households had shorter sleep durations (β = -0.03, p < .001). Superior housing quality and family functioning were associated with longer sleep durations (β = 0.04 and 0.02, respectively, ps < .01). The effects of housing quality and family functioning on sleep duration were mediated by maternal mental health.

CONCLUSIONS

Both physical and social characteristics of the family environment are critical to sleep duration in children. The effects of family environment characteristics on sleep duration in children are in part mediated by maternal mental health. Interventions to improve sleep during childhood by targeting the family environment may be more effective when maternal mental health is considered.

COVID-19 affects psychological symptoms of pregnant women indirectly by increasing their maternal concerns

BACKGROUND

Pregnant women themselves are at higher risk for psychological symptoms. The impact of ongoing COVID-19 may increase the risk. However, it is uncertain whether COVID-19 affects pregnant women's psychological symptoms directly or indirectly being mediated.

METHODS

This survey was conducted in four obstetrics and gynecology hospitals in Beijing from February 28, 2020, to April 26, 2020. Pregnant women who visited the antenatal-care clinic were mobilized to finish the online questionnaires, including the Generalized Anxiety Disorder 7-Item Scale, Patient Health Questionnaire-9, Connor-Davidson resilience scale, and Insomnia Severity Index.

RESULTS

A total of 828 pregnant women were included in the analysis. The estimated self-reported rates of anxiety, depression, insomnia, and any of the three were 12.2 %, 24.3 %, 13.3 %, and 33.1 %, respectively. Mediating effect analysis showed that pregnant women's response to COVID-19 was not directly associated with psychological symptoms but indirectly through the mediating effect of maternal concerns, which accounted for 32.35 % of the total effect. Stratified analysis by psychological resilience showed that women's attitude toward COVID-19 (OR, 2.68, 95 % CI: 1.16-6.18) was associated with a higher risk of psychological symptoms in those with poor psychological resilience.

LIMITATIONS

The study was a non-probability sampling survey, and the causal relationship between maternal concerns and psychological symptoms could not be determined due to the study's design.

CONCLUSIONS

Under public health emergencies such as COVID-19, routine antenatal care should still be prioritized, and concerns related to childbirth-related caused by such emergencies should also be addressed, especially for those with weak psychological resilience.

Subcortical brain volumes in young infants exposed to antenatal maternal depression: Findings from a South African birth cohort

BACKGROUND

Several studies have reported enlarged amygdala and smaller hippocampus volumes in children and adolescents exposed to maternal depression. It is unclear whether similar volumetric differences are detectable in the infants' first weeks of life, following exposure in utero. We investigated subcortical volumes in 2-to-6 week old infants exposed to antenatal maternal depression (AMD) from a South African birth cohort.

METHODS

AMD was measured with the Beck Depression Inventory 2nd edition (BDI-II) at 28-32 weeks gestation. T2-weighted structural images were acquired during natural sleep on a 3T Siemens Allegra scanner. Subcortical regions were segmented based on the University of North Carolina neonatal brain atlas. Volumetric estimates were compared between AMD-exposed (BDI-II ⩾ 20) and unexposed (BDI-II < 14) infants, adjusted for age, sex and total intracranial volume using analysis of covariance.

RESULTS

Larger volumes were observed in AMD-exposed (N = 49) compared to unexposed infants (N = 75) for the right amygdala (1.93% difference, p = 0.039) and bilateral caudate nucleus (left: 5.79% difference, p = 0.001; right: 6.09% difference, p < 0.001). A significant AMD-by-sex interaction was found for the hippocampus (left: F(1,118) = 4.80, p = 0.030; right: F(1,118) = 5.16, p = 0.025), reflecting greater volume in AMD-exposed females (left: 5.09% difference, p = 0.001, right: 3.54% difference, p = 0.010), but not males.

CONCLUSIONS

Volumetric differences in subcortical regions can be detected in AMD-exposed infants soon after birth, suggesting structural changes may occur in utero. Female infants might exhibit volumetric changes that are not observed in male infants. The potential mechanisms underlying these early volumetric differences, and their significance for long-term child mental health, require further investigation.

Trajectories of Depression Symptoms From Pregnancy Through 24 months Postpartum Among Kenyan Women Living With HIV

BACKGROUND

We examined longitudinal patterns and cofactors of depressive symptoms among pregnant and postpartum women living with HIV (WLWH).

METHODS

This study used data from a randomized trial of a text messaging intervention. WLWH were serially assessed for depressive symptoms from pregnancy through 24 months postpartum at 6 time points (pregnancy, 6 weeks, and 6, 12, 18, and 24 months postpartum). Depressive symptoms were assessed using Patient Health Questionnaire-9 and longitudinal patterns using group-based trajectory modeling. Moderate-to-severe depressive symptoms (MSD) correlates were assessed using generalized estimating equations.

RESULTS

Among 824 enrolled women, 14.6% ever had MSD during pregnancy or postpartum; 8.6% of WLWH had MSD in pregnancy and 9.0% any postpartum MSD. MSD was associated with abuse [RR: 3.8, 95% confidence interval (CI): 2.6 to 5.4], stigma (RR: 4.4, 95% CI: 3.1 to 6.3), and food insecurity (RR: 2.7, 95% CI: 1.9 to 3.8). Unintended pregnancy (RR: 1.6, 95% CI: 1.1 to 2.3) and recent HIV diagnosis (RR: 1.8, 95% CI: 1.2 to 2.6) were associated with higher MSD risk, whereas HIV status disclosure to partner (RR: 0.3, 95% CI: 0.2 to 0.6) and social support (RR: 0.97, 95% CI: 0.96 to 0.98) were associated with lower risk. Trajectory modeling identified 4 phenotypes of peripartum depressive symptoms: persistent no/low symptoms (38.5%), mild symptoms resolving postpartum (12.6%), low symptoms increasing slightly in postpartum (47.9%), and persistent moderate-severe symptoms throughout (1.1%).

CONCLUSIONS

WLWH attending PMTCT services had varied patterns of depressive symptoms, which were associated with stressors (recent diagnosis and food insecurity) and factors reflecting low social power (abuse, stigma, and unintended pregnancy). Women experiencing concurrent abuse, stigma, and food insecurity should be prioritized for interventions to prevent persistent depression.
