Developmental impairment in children exposed during pregnancy to maternal SARS-COV2: A Brazilian cohort study.

OBJECTIVES: To determine the effects of in-utero exposure to maternal SARS-CoV-2 infection on offspring's neurodevelopment during the first year of life. METHODS: We performed a prospective cohort of babies exposed to SARS-CoV-2 during pregnancy, and a control group (CG) of unexposed babies in a low-income area in Brazil. Children's neurodevelopment was assessed using the guide for Monitoring Child Development in the Integrated Management of Childhood Illness context for both groups (at 1,2,3,4,5,6, 9, and 12 months), and the Ages & Stages Questionnaire (ASQ-3) for the exposed group (EG) (at 4, 6 and 12 months). RESULTS: We followed 137 children for 1 year, 69 in the COVID-19-EG, and 68 in the CG. All mothers were unvaccinated at the time of cohort inclusion, and maternal demographics were similar in the two groups. 20.3% of EG children and 5.9% of the CG received a diagnosis of neurodevelopmental delay within 12 months of life (P = 0.013, relative risk = 3.44; 95% confidence interval, 1.19- 9.95). For the EG, the prevalence of neurodevelopment impairment using Ages & Stages Questionnaire was 35.7% at 4 months, 7% at 6 months, and 32.1% at 12 months. CONCLUSION: SARS-CoV-2 exposure was associated with neurodevelopmental impairment, and specific guidelines are needed for the follow-up of these high-risk children to mitigate the long-term effects on children's health.

Trajectory of maternal depression and parasomnias.

Maternal depressive symptoms are associated with poorer sleep quality in their children. Although parasomnias can occur at any age, this group of sleep disorders is more common in children. The aim of this study was to assess whether maternal depression trajectories predict parasomnias at the age of 11 years. Data were from a Birth Cohort of 4231 individuals followed in the city of Pelotas, Brazil. Maternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale (EPDS) at 12, 24, and 48 months, and 6 and 11 years postpartum. Maternal depression trajectories were calculated using a group-based modelling approach. Information on any parasomnias (confused arousals, sleepwalking, night terrors, and nightmares) was provided by the mother. Five trajectories of maternal depressive symptoms were identified: chronic-low (34.9%), chronic-moderate (41.4%), increasing (10.3%), decreasing (8.9%), and chronic-high (4.4%). The prevalence of any parasomnia at the age of 11 years was 16.8% (95% confidence interval [CI] 15.6%-18.1%). Confusional arousal was the most prevalent type of parasomnia (14.5%) and varied from 8.7% to 14.7%, 22.9%, 20.3%, and 27.5% among children of mothers at chronic-low, moderate-low, increasing, decreasing, and chronic-high trajectories, respectively (p < 0.001). Compared to children from mothers in the chronic-low trajectory, the adjusted prevalence ratio for any parasomnia was 1.58 (95% CI 1.29-1.94), 2.34 (95% CI 1.83-2.98), 2.15 (95% CI 1.65-2.81), and 3.07 (95% CI 2.31-4.07) among those from mothers in the moderate-low, increasing, decreasing, and chronic-high trajectory groups, respectively (p < 0.001). In conclusion, parasomnias were more prevalent among children of mothers with chronic symptoms of depression.

Effects of SARS-CoV-2 gestational exposure and risk factors on neurodevelopment until 12 months: A prospective cohort study in Brazil.

BACKGROUND: The effects of SARS-CoV-2 gestational exposure on child development remain inconclusive. AIMS: To analyze the effects of SARS-CoV-2 gestational exposure on neurodevelopment until 12 months. STUDY DESIGN: Prospective cohort study conducted in five municipalities in Southeast Brazil from August 2021 to September 2022. SUBJECTS: Infants were recruited from a serological survey performed during neonatal screening and followed up to 12 months old. We included 224 infants exposed to SARS-CoV-2 during pregnancy and 225 non-exposed, according to the serology results of the newborn as well as their mothers and the maternal antenatal RT-PCR results. OUTCOME MEASURES: Developmental assessments were performed at 6 and 12 months using the Survey of Wellbeing of Young Children-Brazilian Version (SWYC-BR). Children with suspected developmental delay (SDD) at 6 and 12 months were considered at high risk for developmental delay (HRDD). Additionally, risk factors associated with SDD were examined. RESULTS: There were 111 children identified with SDD and 52 with HRDD. SARS-CoV-2 gestational exposure was not associated with SDD. Exposure in the first gestational trimester increased SDD risk by 2.15 times compared to the third. Cesarean delivery predicted SDD (OR 1.56; 95%CI 1.01-2.42) and HRDD (OR 1.91; 95%CI 1.04-3.48). Additionally, suspected maternal depression predicted SDD (OR 1.76; 95%CI 1.01-3.10). CONCLUSION: SARS-CoV-2 gestational exposure did not increase the developmental delay risk. However, our findings suggest that the earlier the gestational exposure, the greater the developmental delay risk at 12 months. Cesarean delivery and suspected maternal depression increased the developmental delay risk, independent of virus exposure.

Correlates of maternal depression, anxiety and functioning across an urban-rural gradient in northern Ecuador.

Maternal depression remains under characterised in many low- and middle-income countries, especially in rural settings. We aimed to describe maternal depression and anxiety symptoms in rural and urban communities in northern Ecuador and to identify socioeconomic and demographic factors associated with these symptoms. Data from 508 mothers participating in a longitudinal cohort study were included. Depression and anxiety symptoms were assessed using the Hopkins Symptom Checklist (HSCL-25), and maternal psychological functioning was assessed using a checklist of daily activities. Tobit regression models were used to examine associations with sociodemographic variables and urbanicity. The median HSCL-25 score was 1.2 (IQR: 0.4) and 14% of women scored above the threshold for clinically relevant symptoms. Rural women reported similar food insecurity, less education, younger age of first pregnancy, and lower socio-economic status compared to their urban counterparts. After adjusting for these factors, rural women reported lower HSCL-25 scores compared to women lin urban areas (ß = -0.48, 95%CI:0.65, -0.31). Rural residence was also associated with lower depression and anxiety HSCL-25 sub-scale scores, and similar levels of maternal functioning, compared to urban residence. Our results suggest that both household and community-level factors are risk factors for maternal depression and anxiety in this context.

Pathways from maternal depression to child resilience: Socioeconomic, family, and individual factors in the 2004 Pelotas (Brazil) birth cohort.

Background: The negative impacts of maternal depression on child mental health outcomes are well-documented. However, some children show adaptive functioning following exposure to maternal depression, demonstrating resilience. In a large birth cohort from Brazil, a middle-income country, we examined direct and indirect pathways, considering socioeconomic, family, and individual factors, contributing to the development of resilience. Methods: Using data from the 2004 Pelotas Birth Cohort (N = 4231), we restricted the sample to those exposed to maternal depression up to age 6 years (depression present at ≥2 out of 5 assessment waves; n = 1132; 50% boys). Resilience was defined as scoring below or equal to the mean of the unexposed group on all four problem subscales of the parent-report Strengths and Difficulties Questionnaire at age 11 years. We examined pathways from socioeconomic status (SES; measured at birth) to resilience via cognitive stimulation (CS) (at 24 and 48 months) and Intelligence quotient (IQ) (at 6 years), and from CS to resilience via IQ, using counterfactual mediation. Results: A minority of children exposed to maternal depression showed resilience (12.4%). There was evidence of indirect pathways from SES to resilience via CS (odds ratio (OR) = 1.76, 95% confidence interval (CI) 1.02-3.38) and IQ (OR = 1.19, 95% CI 1.01-1.42), such that higher SES was associated with resilience via both higher levels of CS and higher IQ, which, in turn, were each positively associated with resilience. Furthermore, there was evidence of a direct (OR = 1.86, 95% CI 1.01-3.76) and total effect (OR = 1.94, 95% CI 1.05-3.89) of CS on resilience, even after controlling for SES. However, these effects varied depending on how persistent and severe depression was defined. Conclusions: These findings suggest that CS in early childhood may represent a modifiable protective factor for children exposed to maternal depression and a promising intervention target to promote child resilience in the context of maternal depression exposure.

Smartphone-assisted online brief cognitive behavioral therapy to treat maternal depression: findings of a randomized controlled trial

Objective: To test the efficacy of smartphone-assisted online brief cognitive behavioral therapy (b-CBT) to treat maternal depression compared to online brief CBT plus an active control app. Methods: A randomized controlled trial was conducted. Assessments were performed at baseline (T0), midpoint (T1, week 4-5), post-treatment (T2, week 8), and follow-up (T3, 2-month postnatal follow-up) by blinded interviewers. The primary outcome was depression measured by the Edinburgh Postnatal Depression Scale (EPDS) at T2. We also assessed anxiety, stress, sleep quality, well-being, physical activity, treatment response, and offspring child behavior problems. Results: Eighty-one participants were randomized to the intervention (n=37) or active control (n=44) groups. Seventy-one participants completed the post-treatment assessment or reported primary outcome data. No differences were found between the intervention and active control groups regarding maternal depression or other mental health outcomes. Overall, we found large within-group effect sizes, with 80% of the total sample responding to treatment. Conclusions: Our data showed no difference between the groups, suggesting that adding apps to psychotherapy treatment may not enhance treatment effects on prenatal depression. A within-groups analysis showed that most participants with depression responded to treatment; however, future studies are needed to confirm whether this effect is related to factors other than the intervention.

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.

Postpartum depression in rats causes poor maternal care and neurochemical alterations on dams and long-lasting impairment in sociability on the offspring

Postpartum depression is a mentally disabling disease with multifactorial etiology that affects women worldwide. It can also influence child development and lead to behavioral and cognitive alterations. Despite the high prevalence, the disease is underdiagnosed and poorly studied. To study the postpartum depression caused by maternal separation model in rats, dams were separated from their litter for 3 h daily starting from lactating day (LD) 2 through LD12. Maternal studies were conducted from LD5 to LD21 and the offspring studies from postnatal day (PND) 2 through PND90. The stress caused by the dam-offspring separation led to poor maternal care and a transient increase in anxiety in the offspring detected during infancy. The female offspring also exhibited a permanent impairment in sociability during adult life. These changes were associated with neurochemical alterations in the prefrontal cortex and hippocampus, and low TSH concentrations in the dams, and in the hypothalamus, hippocampus and striatum of the offspring. These results indicate that the postpartum depression resulted in a depressive phenotype, changes in the brain neurochemistry and in thyroid economy that remained until the end of lactation. Changes observed in the offspring were long-lasting and resemble what is observed in children of depressant mothers.

Maternal depression and offspring mental health at age 5: MINA-Brazil cohort study / Depressão materna e saúde mental infantil aos cinco anos de idade: Estudo de coorte MINA-Brasil

ABSTRACT OBJECTIVE: To identify longitudinal patterns of maternal depression between three months and five years after child's birth, to examine predictor variables for these trajectories, and to evaluate whether distinct depression trajectories predict offspring mental health problems at age 5 years. METHODS: We used data from the Maternal and Child Health and Nutrition in Acre (MINA-Brazil) study, a population-based birth cohort in the Western Brazilian Amazon. Maternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale (EPDS) at 3 and 6-8 months, and 1 and 2 years after delivery. Mental health problems in 5-year-old children were evaluated with the Strengths and Difficulties Questionnaire (SDQ) reported by parents. Trajectories of maternal depression were calculated using a group-based modelling approach. RESULTS: We identified four trajectories of maternal depressive symptoms: "low" (67.1%), "increasing" (11.5%), "decreasing" (17.4%), and "high-chronic" (4.0%). Women in the "high/chronic" trajectory were the poorest, least educated, and oldest compared with women in the other trajectory groups. Also, they were more frequently multiparous and reported smoking and having attended fewer prenatal consultations during pregnancy. In the adjusted analyses, the odds ratio of any SDQ disorder was 3.23 (95%CI: 2.00-5.22) and 2.87 (95%CI: 1.09-7.57) times higher among children of mothers belonging to the "increasing" and "high-chronic" trajectory groups, respectively, compared with those of mothers in the "low" depressive symptoms group. These differences were not explained by maternal and child characteristics included in multivariate analyses. CONCLUSIONS: We identified poorer mental health outcomes for children of mothers assigned to the "chronic/severe" and "increasing" depressive symptoms trajectories. Prevention and treatment initiatives to avoid the adverse short, medium, and long-term effects of maternal depression on offspring development should focus on women belonging to these groups.

RESUMO OBJETIVO: Identificar padrões longitudinais de depressão materna entre três meses e cinco anos após o nascimento de seus filhos, analisar variáveis preditoras dessas trajetórias e avaliar se trajetórias distintas de depressão predizem problemas de saúde mental infantil aos cinco anos de idade. MÉTODOS: Utilizou-se dados do estudo sobre saúde e nutrição materno infantil no Acre (MINA-Brasil), uma coorte de nascimentos de base populacional na Amazônia ocidental brasileira. Os sintomas depressivos maternos foram avaliados pela Escala de Depressão Pós-parto de Edimburgo (EPDS) aos 3 e 6-8 meses e 1 e 2 anos após o parto. Problemas de saúde mental em crianças com cinco anos de idade foram avaliados pelo Questionário de Capacidades e Dificuldades (SDQ- Strengths and Difficulties Questionnaire), respondido pelos pais. As trajetórias de depressão materna foram calculadas usando uma abordagem de modelagem baseada em grupos. RESULTADOS: Foram identificadas quatro trajetórias de sintomas depressivos maternos: "baixa" (67,1%), "crescente" (11,5%), "decrescente" (17,4%) e "alta-crônica" (4,0%). As mulheres na trajetória "alta/crônica" eram mais pobres, menos escolarizadas, mais velhas e multíparas e relataram tabagismo com maior frequência e menor número de consultas de pré-natal durante a gestação do que as demais. Nas análises ajustadas, a razão de chances de qualquer transtorno do SDQ foi 3,23 (IC95%:2,00-5,22) e 2,87 (IC95%: 1,09-7,57) vezes maior entre os filhos de mães nos grupos de trajetória "crescente" e "alta-crônica", respectivamente, do que de mães do grupo de sintomas depressivos "baixos". As características maternas e infantis incluídas nas análises multivariadas foram incapazes de explicar essas diferenças. CONCLUSÕES: Identificou-se piores desfechos de saúde mental para filhos de mães atribuídas às trajetórias "crônica/grave" e "crescente" de sintomas depressivos. Iniciativas de prevenção e tratamento para evitar os efeitos adversos a curto, médio e longo prazo da depressão materna sobre o desenvolvimento de seus filhos devem se concentrar principalmente nas mulheres nesses grupos.

Analysis of Motherhood Constellation among Adolescent Mothers With and Without Depressive Symptoms / Análise da Constelação da Maternidade em Mães Jovens com e sem Sintomas Depressivos

ABSTRACT This study analyzed the Motherhood Constellation in two young mothers (19 and 22 years old), with and without depressive symptoms. Through qualitative content analysis of the interviews, information was categorized according to four themes of this construct: life-growth, primary relating, support matrix, and identity reorganization. There were no differences between mothers in the first theme. In the others, despite the similarities with the asymptomatic mother, the young woman with depressive symptoms had difficulty to get involved with her baby, restricted social support, and an impasse related to the organization of her maternal identity and internal reorganization in the face of developmental demands. These findings indicate the need for attention to the mental health of young mothers during the complex process of becoming a mother.

RESUMO Este estudo investigou a Constelação da Maternidade em duas mães jovens (19 e 22 anos), com e sem sintomas depressivos. Através da análise de conteúdo qualitativa das entrevistas, as informações foram categorizadas conforme os quatro temas desse constructo: vida-crescimento, relacionar-se primário, matriz de apoio e reorganização da identidade. Não foram observadas diferenças entre as mães no primeiro tema. Nos demais, apesar das semelhanças com a mãe assintomática, a jovem com sintomas depressivos apresentou dificuldade no envolvimento com seu bebê, apoio social restrito e impasse relacionado à organização da identidade materna e reorganização interna perante as demandas desenvolvimentais. Esses achados indicam a necessidade de atenção à saúde mental de mães jovens durante o complexo processo de tornar-se mãe.

Does Maternal Mental Health and Maternal Stress Affect Preschoolers' Behavioral Symptoms?

(1) Background: Maternal stress and depression are considered risk factors in children's socioemotional development, also showing high prevalence worldwide. (2) Method: Participants correspond to a longitudinal sample of 6335 mother/child pairs (18-72 months), who were surveyed in 2010 and then in 2012. The hypothesis was tested with SEM analysis, setting the child's internalized/externalized problems as dependent variable, maternal depression as independent variable, and stress as a partial mediator. (3) Results: Both depression during pregnancy and recent depression has not only a direct effect on the internalizing and externalizing symptomatology of the child, but also an indirect effect through parental stress. Significant direct and indirect relationships were found. (4) Conclusions: Maternal depression and the presence of parental stress can influence children's behavioral problems, both internalizing and externalizing.

Association of maternal depression, family composition and poverty with maternal care and physical health of children in the first year of life / Associação da depressão materna, composição da família e pobreza com os cuidados maternos e a saúde física de crianças no primeiro ano de vida

INTRODUCTION: The child's overall health depends on several factors, including the quality of the environment in which it lives and the care it receives. Child well-being early in life has an impact on its future and future generations' health. OBJECTIVE: Analyze the association of maternal depression, family composition, and socioeconomic conditions with the indicator of maternal care and physical health of children. METHODS: Retrospective cohort that analyzed data from 120 children during their first year of life. A Health and Maternal Care Indicator (ISCM) was created, aggregating information on growth, breastfeeding, vaccination, prophylaxis of iron deficiency anemia, illnesses, and accidents. The socioeconomic and health conditions were obtained through a structured interview. The Edinburgh Postnatal Depression Scale assessed maternal depression. Quasipoisson Regression examined the association between the ICSM and the predictors. The initial model considered p<0.25 in the univariate analysis and p<0.05 in the final model. RESULTS: The mothers were adults (83.3%), studied for an average of 10 years, and 36% had depressive symptoms. About 37% of the families were single-parent female, 59% were from Class C1-C2 of ABEP, and 12% received the "Bolsa Família" benefit. ISCM was 8% lower in children whose mothers were depressed (p = 0.04) or had no partner (p = 0.03), and was 14% higher in families receiving Bolsa Família (p = 0.02) in relation to their peers. CONCLUSION: Maternal depression and female single-parent family arrangements negatively impacted child health and care, while the conditional cash transfer program represented a protective factor.

INTRODUÇÃO: A saúde integral da criança depende de vários fatores, entre eles a qualidade do ambiente em que vive e dos cuidados que recebe. O bem-estar da criança no início da vida tem impacto na sua saúde futura e das próximas gerações. OBJETIVO: Analisar a associação da depressão materna, composição da família e condições socioeconômicas com o indicador de cuidados maternos e saúde física de crianças. MÉTODO: Coorte retrospectiva que analisou dados de 120 crianças no primeiro ano de vida. Foi criado um Indicador de Saúde e Cuidados Maternos (ISCM), agregando informações sobre crescimento, aleitamento materno, vacinação, profilaxia de anemia ferropriva, adoecimentos e acidentes. A condição socioeconômica e de saúde foram obtidas por entrevista estruturada. A depressão materna foi avaliada pela Edinburgh Postnatal Depression Scale. A associação entre o ICSM e os preditores foi examinada pela Regressão de Quasipoisson. O modelo inicial foi composto por variáveis com p<0,25 na análise univariada e p<0,05 no modelo final. RESULTADOS: As mães eram adultas (83,3%), estudaram, em média, por 10 anos e 36% delas apresentaram sintomas depressivos. Cerca de 37% das famílias eram do tipo monoparental feminino, 59% eram da Classe C1-C2 da ABEP e 12% recebiam o benefício "Bolsa Família". O ISCM foi 8% menor nas crianças cujas mães eram deprimidas (p=0,04) ou não tinham companheiro (p=0,03), e foi 14% maior nas famílias que recebiam o Bolsa família (p=0,02) em relação aos seus pares. CONCLUSÃO: A depressão materna e o arranjo familiar monoparental feminino impactaram negativamente a saúde e os cuidados com a criança, enquanto o programa de transferência condicionada de renda representou um fator de proteção.

A smartphone-assisted brief online cognitive-behavioral intervention for pregnant women with depression: a study protocol of a randomized controlled trial.

BACKGROUND: Pregnancy is strongly associated with increased risk for depression. Approximately 25% of pregnant women develop depression. Treatment for depression during pregnancy has several complexities: the use of psychiatric medications during pregnancy might result in developmental problems in the child and must be used with caution. Psychosocial interventions are effective, but they require specialized professionals. Low- and middle-income countries (LMIC) such as Brazil do not have enough mental health professionals needed to meet this demand. In this context, smartphone-based interventions show immense potential. We developed Motherly, a smartphone application (app) designed to treat maternal depression. We aim to test the efficacy of Motherly in addition to brief cognitive-behavioral therapies (CBT) to treat maternal depression. METHODS: We will conduct a 2-arm parallel-randomized controlled clinical trial in which 70 pregnant women aged between 16 and 40 years with depression will be randomized to intervention or active control. The intervention group will have access to Motherly, a smartphone app based on three concepts: psychoeducation, behavior monitoring, and gaming elements. Motherly is composed of a package of interventions composed of modules: mental health, sleep, nutrition, physical activity, social support, prenatal/postnatal support, and educational content. The main focus of Motherly is delivering behavioral activation (BA), a brief and structured psychological treatment. The app allows participants to schedule and engage in, and monitor activities according to a plan to avoid acting exclusively according to their mood. The active control group will have access to a simplified version of the app consisting of educational content about various aspects of pregnancy, maternal physical and mental health, and infant development (BA, activity scheduling, sleep hygiene, among other functionalities, will not be present in this version). Both groups will receive four sessions of brief CBT in 8 weeks. Participants will be evaluated by assessors blind to randomization and allocation status. Assessments will occur at baseline (T0), midpoint (T1, week 4-5), posttreatment (T2, week 8), and follow-up (T3, when the child is 2 months old). Maternal mental health (prenatal anxiety, psychological well-being, perceived stress, depression, depression severity, and sleep quality), quality of life, physical activity levels, and infant developmental milestones and social/emotional problems will be measured. Our primary outcome is the change in maternal prenatal depression from baseline to posttreatment (8 weeks). DISCUSSION: The potential of digital technology to deliver mental health interventions has been increasingly recognized worldwide. There is a growing literature on interventions using smartphone applications to promote mental health, both with or without the intermediation of a mental health professional. Our study adds to the literature by testing whether an app providing an intervention package, including CBT, psychoeducation, nutrition, physical activity, and social support, can promote maternal and child health and well-being. In particular, we aim to treat depression, for which the use of digital technologies is still scarce. Smartphone applications designed to treat maternal depression are especially relevant because of the potential to circumvent barriers that prevent pregnant women from accessing mental health care.

Post-partum depression: a cross-sectional study of women enrolled in a conditional cash transfer program in 30 Brazilian cities.

OBJECTIVE: Investigate factors associated with symptoms of postpartum depression in mothers from families in social vulnerability. METHODS: Information was used from the baseline of a randomized trial to assess a child development program that enrolled 3,242 children < 12 months of age from beneficiary families of the Bolsa Família Program residing in 30 municipalities (counties) in six states of Brazil. The Edinburgh Postnatal Depression Scale (EPDS) was applied to the mothers, and depression was defined as score ≥10. Information on the mother (schooling, age, parity, marital status, skin color, smoking, number of prenatal appointments, and planning of the pregnancy), family (paternal schooling, household crowding, support from the child's father and the family during the pregnancy, and number of children under 7 years living in the household), and infant (sex, gestational age, birthweight, Apgar score, and child's age at the time of the interview) was collected. Prevalence rates for depressive symptoms were calculated with crude and adjusted odds ratios (OR) and 95% confidence intervals (95%CI), using hierarchical logistic regression, in a multilevel model. RESULTS: The analysis included 3,174 mothers with information on EPDS. The interviews were conducted on average 7.9 months (standard deviation= 2.9) after childbirth. Overall prevalence of depressive symptoms was 26.5% (25.0-28.1%). In the adjusted analysis, higher parity was associated with higher odds of postpartum depression (p <0.001). Women with ≥3 previous deliveries showed an odds 84% higher of presenting depressive symptoms (OR= 1.84; 1.43-2.35) than primiparae. Higher maternal and paternal schooling, presence of husband or partner, and having received support from the child's father and the family during the pregnancy were protective factors against postpartum depression. CONCLUSION: The study showed high prevalence of postpartum depressive symptoms. Promotion of parental education, alongside with the promotion of support to the woman during pregnancy by the child's father and by the family, as well as family planning leading to birth spacing are measures that may help to prevent postpartum depressive symptoms.

Maternal Depressive Symptoms, Lung Function, and Severe Asthma Exacerbations in Puerto Rican Children.

BACKGROUND: Maternal depression has been linked to health care use for asthma in cross-sectional or short-term follow-up studies of school-aged children. OBJECTIVE: To examine whether increased or persistent maternal depressive symptoms over approximately 5 years are associated with severe asthma exacerbations or worse lung function in youth. METHODS: A prospective study of 386 youth living in Puerto Rico, aged 6 to 14 years at a baseline visit and 9 to 20 years at a second visit, was performed. Our exposure of interest was change in persistence of maternal depressive symptoms, assessed at both visits using the Center for Epidemiologic Studies Depression Scale (CESD). Our outcomes of interest were change in percent predicted forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) between the first and second visits in all subjects, and ≥1 severe asthma exacerbation in the year before the second visit in subjects with asthma. RESULTS: In a multivariable analysis, each 1-point increment in the CESD score was associated with decrements of 0.15% in percent predicted FEV1 (95% confidence interval [CI] = -0.28% to -0.01%; P = .03) and 0.10% in percent predicted FEV1/FVC (95% CI = -0.20% to 0.001%; P = .05) between visits, as well as with 1.03 times increased odds of ≥1 severe asthma exacerbation at the second visit (95% CI for odds ratio = 0.99 to 1.06, P = .09). In a multivariable analysis, the presence of maternal depressive symptoms (a CESD score ≥21 points) at the second visit or at both visits was significantly associated with 3.17 to 3.52 times increased odds of ≥1 severe asthma exacerbation in the year before the second visit. CONCLUSIONS: Increasing or persistent maternal depressive symptoms over approximately 5 years are associated with worse lung function measures and severe asthma exacerbations among Puerto Rican youth, a high-risk population.

Maternal depression trajectories and offspring positive attributes and social aptitudes at early adolescence: 2004 Pelotas birth cohort.

There is growing evidence that adolescent positive attributes and social aptitudes are associated with beneficial outcomes, including higher educational attainment and lower risk of later psychiatric disorder. Although maternal depression is a well-known risk factor for a variety of offspring adverse outcomes, less is known on its repercussion on children's positive behavioral traits. This study aimed to evaluate the impact of maternal depression trajectories on offspring positive attributes and social aptitudes, testing sex-moderated models for the studied association. The 2004 Pelotas Birth Cohort is an ongoing cohort originally comprised by 4231 live births from Brazil. We included 3465 11-year-old adolescents (48.6% female; maternal self-reported skin color: 27.0% non-white). Maternal depressive symptoms were assessed by the Edinburgh Postnatal Depression Scale (EPDS) at all follow-ups. Adolescent positive attributes and social aptitudes were ascertained by specific subscales of Development and Well-Being Assessment (DAWBA). Multivariate linear regression was used to examine the effect of maternal depression trajectories on offspring's outcomes, adjusting for potential confounding variables. Moderation was assessed with interaction terms. Adolescents from mothers who presented high-chronic levels of depressive symptoms during offspring's life have lower scores of positive attributes and social aptitudes. Boys exposed to maternal depression during their lifetime are more affected than girls regarding positive attributes, but this sex difference was not observed for social aptitudes. Interventions targeting the promotion of adaptive behavioral traits may represent an effective way to buffer the adverse impact of maternal depression on offspring development, especially for vulnerable groups such as male adolescents.

Infant iron deficiency, iron supplementation, and psychosocial stress as predictors of neurocognitive development in Chilean adolescents.

Objective: The aim of the current study was to examine the unique and joint contributions of iron deficiency, iron supplementation, and psychosocial stress in infancy and stress in adolescence to neurocognitive functioning in adolescence.Methods: The current study (N = 796; Mage = 14.4y) involved a prospective cohort of low- and middle-socioeconomic status adolescents in Santiago, Chile. As infants, they had participated in an iron supplementation trial. Infant iron status was assessed at 12-18 months, and mothers answered questions about family psychosocial stress at 6-12 months and in adolescence (maternal depressive symptoms, home support for child development, stressful life events, father absence, socioeconomic status, and parental education). Neurocognitive functioning was assessed in adolescence using the Balloon Analogue Risk Task, Stockings of Cambridge, Trail Making Test, Purdue Pegboard Test, and Wisconsin Card Sorting Test.Results: Greater psychosocial stress in infancy predicted less risk-taking, poorer planning abilities and fluid cognition, and slower processing speed in adolescence. Iron deficiency anemia in infancy predicted less risk-taking. Greater adolescent psychosocial stress predicted difficulties in set-shifting. There were no interactions between infant psychosocial stress and iron deficiency predicting adolescent neurocognitive functioning.Conclusion: These results suggest that interventions to reduce infant psychosocial stress may be more likely to prevent multiple neurocognitive deficits in adolescence than interventions to reduce infant iron deficiency.

Intervención grupal para díadas madre- infante privadas de libertad: efectos sobre la depresión materna y el desarrollo infantil / Group Intervention for Imprisoned Mother-Infant Dyads: Effects on Mother's Depression and on Children's Development

Resumen La sintomatología depresiva es frecuente en las mujeres durante el período periparto, impacta negativamente el desarrollo infantil y puede mostrar un incremento cuando la maternidad se desarrolla en contextos carcelarios. Objetivo: realizar intervenciones grupales en dos grupos, uno conformado por mujeres embarazadas y otro por díadas madre-infante, que se encontraban cumpliendo condena en cárceles chilenas, y evaluar su efecto en la sintomatología depresiva materna y en el desarrollo socioemocional infantil. Método: Participaron 60 madres recluidas en recintos carcelarios chilenos, 30 embarazadas y 30 díadas (madres-infante). Se realizaron análisis de regresión multinivel para medidas repetidas de la sintomatología depresiva materna (BDI) en ambos grupos y del desarrollo socioemocional (ASQ-SE) en los niños/as participantes en la intervención para díadas. Resultados: se observó una reducción significativa de la sintomatología depresiva en las mujeres embarazadas (b=-3.60, t(29)=-2.66, p=.031) y en las madres con hijos/as nacidos (b=-0.1499, t(93)=-5.3, p=<.001), así como una reducción de las dificultades en el desarrollo socioemocional infantil (b=-15.26, t(18)=-4.107, p=.001). Conclusión: se discute la relevancia de contar con alternativas psicoterapéuticas para el abordaje de la depresión en madres privadas de libertad y la promoción de un desarrollo socioemocional saludable de sus hijos/as.

Abstract Women may frequently present depressive symptomatology during the peripartum period, it impacts negatively child development and may show an increase when motherhood takes place in prison contexts. Furthermore, the negative effects of maternal depression on children's development have been demonstrated by research findings. Aim: To evaluate the effect of two group interventions for pregnant women and mother-infant dyads with children under 2 years of age, on maternal depressive symptomatology and on the children's development. Method: The sample considered 60 incarcerated women from Chilean prisons all over the country; 30 pregnant women and 30 mothers with children under 2 years of age. Multilevel regression analysis for repeated measures were performed for maternal symptomatology (BDI) in both groups and for children's development (ASQ-SE) in the dyad's group. Results: It was observed Significant reductions in the depressive symptomatology frequencies in the pregnant women (b=-3.60, t(29)=-2.66, p=.031) and in the mothers who participated in the dyad's intervention group (b=-0.1499, t(93)=-5.3, p=<.001), as well as a reduction in child social-emotional development difficulties (b=-15.26, t(18)=-4.107, p=.001). Conclusion: The discussion section addresses the relevance of providing psychological support to imprisoned mother/child dyads, to treat maternal depression and to promote a healthy development of the children who grow up in prison contexts.

Behavioral problems and their relationship to maternal depression, marital relationships, social skills and parenting.

Behavioral problems have been associated with multiple variables; however, studies simultaneously investigating parenting practices, marital relationships in bi-parental families, maternal depression, and child behavior remain a gap in the literature. The objective was to verify associations between positive and negative parenting practices, marital relationships, social skills, and behavioral problems among children from bi-parental families with and those without maternal depression; to identify the predictive effect of positive and negative parenting practices, marital relationships, children's social skills, and maternal depression, for internalizing, externalizing behavior problems and internalizing and externalizing comorbidities. A case-control study with a cross-sectional design was adopted to ensure the groups were homogeneous in regard to the children's, mothers', and families' sociodemographic characteristics. A total of 35 mothers currently with depression and 35 without depression indicators participated in the study, while the children were 25 preschoolers and 23 school-aged children. The mothers responded to instruments addressing depression, child behavior, parenting practices, and marital relationships. The results reveal maternal depression associated with marital relationships, positive parenting, and context variables. Maternal depression and marital relationship were found to influence externalizing problems; maternal depression, child-rearing practices, marital relationships, and the children's behavioral repertoires influence internalizing and externalizing comorbidities; and none of the independent variables influenced the occurrence of internalizing problems.
