Assisted reproductive technologies could be associated with higher risk of parenting difficulties in women with postpartum major depression.

No increased risk of postpartum major depression (PPMD) was reported in women conceiving through assisted reproductive technologies (ART). However, ART may be associated with a higher risk of parenting difficulties in women with PPMD. In 359 women with a PPMD admitted to a Mother-Baby Unit (MBU), ART-women (4.2%) showed a 5-fold higher rate of parenting difficulties than those with spontaneous pregnancy (73.33% vs. 35.17%, multivariate ORa = 5.09 [1.48-17.48] p = 0.01). Specific support for mother-child relationship should be implemented in ART-women with PPMD.

French Society for Biological Psychiatry and Neuropsychopharmacology and French-speaking Marcé Society guidelines for the management of mood disorders in women before, during, and after pregnancy.

PURPOSE: The French Society for Biological Psychiatry and Neuropsychopharmacology and the French-speaking Marcé Society have joined forces to establish expert recommendations on the prescription of psychotropic drugs before, during, and after pregnancy in women with major depressive disorder (MDD) and bipolar disorder (BD). METHODS: To elaborate recommendations, we used the RAND/UCLA Appropriateness Method, which combines scientific evidence and expert clinicians' opinions. A written survey was completed by 48 psychiatrists, who have expertise in the management of mood disorders and/or in perinatal psychiatry. Key recommendations are provided by the scientific committee based on data analysis and interpretation of the results of the survey. RESULTS: The recommendations address the following three areas that are deemed essential in women with mood disorders, with an emphasis on screening, treatment options, and monitoring: (i) management of mood disorders in women of childbearing age, (ii) management during pregnancy, (iii) management during the post-partum period. As first-line strategies, experts recommend treating mood symptoms during pregnancy and maintaining a pharmacological treatment, even in euthymic or stabilized patients. First-line options include only medications with no teratogenic risk, and during breastfeeding, only medications without evidence of adverse effects in nursing infants. CONCLUSION: The expert consensus guidelines will help facilitate treatment decisions for clinicians in the daily assessment and management of mood disorders in women of childbearing age, during pregnancy, and in the post-partum period.

Social determinants in prenatal antidepressant use and continuation: Systematic review and meta-analysis.

INTRODUCTION: Depression is one of the most common co-morbidities during pregnancy; with severe symptoms, antidepressants are sometimes recommended. Social determinants are often linked with antidepressant use in the general population, and it is not known if this is the case for pregnant populations. Our objective was to determine if social determinants are associated with prenatal antidepressant intake via a systematic review and meta-analysis. METHODS: A systematic search of five databases was conducted to identify publications from inception to October 2022 that reported associations with prenatal antidepressant intake (use/continuation) and one or more social determinants: education, race, immigration status, relationship, income, or employment. Eligible studies were included in random effects meta-analyses. RESULTS: A total of 23 articles describing 22 studies were included. Education was significantly and positively associated with prenatal antidepressant continuation and heterogeneity was moderate. (Odds ratio = 0.83; 95% CI, 0.78 to 0.89; p < 0.00001; I2 = 53%). Meta-analyses of antidepressant use and education, race, and relationship status, and antidepressant continuation and income were not significant with high levels of heterogeneity. DISCUSSION: While most social determinants in this review were not linked with prenatal antidepressant intake, lower maternal education level does seem to be associated with lower rates of prenatal antidepressant continuation. CONCLUSIONS: Education appears to be linked with prenatal antidepressant intake. The low number of included studies precludes conclusive evidence for other social determinants.

A network analysis of nutritional markers and maternal perinatal mental health in the French EDEN cohort.

BACKGROUND: Perinatal maternal depression and anxiety are associated with adverse maternal outcomes, and nutrition may play an important role in their emergence. Previous research shows that certain micro and macronutrients found in different dietary patterns may associate with perinatal mood disorders. This study aims to explore relationships between nutrition during pregnancy and perinatal maternal depression and anxiety symptoms using network analyses. METHODS: Using data from the French EDEN mother-child cohort, the sample consisted of 1438 women with available mental health outcomes (CES-D, STAI and EPDS) and nutritional markers collected from food frequency questionnaires. Four networks were constructed to explore the relationships between prenatal nutrient status, dietary patterns, and perinatal mental health, while accounting for important confounders. RESULTS: The Healthy dietary pattern was associated with the presence of vital micronutrients, while the Western dietary pattern was consistently associated with poorer intake of specific micronutrients and contained an excess of certain macronutrients. Western dietary pattern and symptoms of postnatal depression were connected by a positive edge in both the macronutrient and micronutrient networks. Lower education levels were associated with higher Western dietary pattern scores, from which a positive edge linked to postnatal depression symptoms in both models. CONCLUSIONS: A Western dietary pattern was associated with increased symptoms of postnatal depression in our adjusted network models; The Healthy dietary pattern was associated with essential micronutrients but not with symptoms of depression or anxiety. Perinatal mental health might be impacted by specific dietary patterns in the context of psychosocial and physical stress associated with pregnancy.

Epigenome-Wide Associations of Placental DNA Methylation and Behavioral and Emotional Difficulties in Children at 3 Years of Age.

The placenta is a key organ for fetal and brain development. Its epigenome can be regarded as a biochemical record of the prenatal environment and a potential mechanism of its association with the future health of the fetus. We investigated associations between placental DNA methylation levels and child behavioral and emotional difficulties, assessed at 3 years of age using the Strengths and Difficulties Questionnaire (SDQ) in 441 mother-child dyads from the EDEN cohort. Hypothesis-driven and exploratory analyses (on differentially methylated probes (EWAS) and regions (DMR)) were adjusted for confounders, technical factors, and cell composition estimates, corrected for multiple comparisons, and stratified by child sex. Hypothesis-driven analyses showed an association of cg26703534 (AHRR) with emotional symptoms, and exploratory analyses identified two probes, cg09126090 (intergenic region) and cg10305789 (PPP1R16B), as negatively associated with peer relationship problems, as well as 33 DMRs, mostly positively associated with at least one of the SDQ subscales. Among girls, most associations were seen with emotional difficulties, whereas in boys, DMRs were as much associated with emotional than behavioral difficulties. This study provides the first evidence of associations between placental DNA methylation and child behavioral and emotional difficulties. Our results suggest sex-specific associations and might provide new insights into the mechanisms of neurodevelopment.

Bipolar disorder in the postpartum period: the impact of a prenatal mood episode on maternal improvement at postpartum discharge after joint inpatient hospitalization.

Bipolar disorder (BD) is linked to a high risk of relapse in the year postpartum. The aim of this study was to search for an association of a mood episode during pregnancy with a lack of maternal improvement after a post-partum episode requiring joint hospitalization. In an observational, naturalist, and multicentric study, 261 women suffering from a BD and jointly hospitalized with their child in a Mother-Baby Unit (MBU) were assessed for risk factors associated with a lack of maternal improvement at discharge. A directed acyclic graph (DAG)-based approach was used to identify confounders to be included in a multiple regression model. In bivariate analyses, a lack of improvement (16.9%) was associated with pregnancy specificities (decompensation, psychotropic treatment, antipsychotics, and benzodiazepines intake), as well as maternal smoking during pregnancy and baby's neonatal hospitalization. In a multivariate analysis based on DAG, a lack of improvement was linked to psychiatric decompensation during pregnancy (OR = 3.31, 95%CI [1.55-7.35], p = 0.002), independently from maternal age, mother's maltreatment during childhood, low level of education, single status, low familial social support, and diagnosis of personality disorder. This study shows the critical importance of mental health during pregnancy in women with BD. Clinical screening and evaluation of the benefit/risk balance of psychotropics during pregnancy are essential.

Impact of pregnancy on antidepressant treatment course: a population-based comparative cohort study in France.

The prevention of relapses and the treatment of depression during pregnancy are difficult challenges. The maintenance of antidepressants in pregnancy with its concomitant risks to mother and child needs to be weighed against those associated with not treating the disease. This study aimed at quantifying the impact of the occurrence of pregnancy on the course of antidepressant treatment among newly treated women (< 6 months). We performed a comparative observational cohort study using the nationwide French reimbursement healthcare system database. Women who conceived in 2014 and initiated an antidepressant at any time in the 6 months before pregnancy were compared with nonpregnant women newly exposed to antidepressants with matching on age, antidepressant exposure, history of psychiatric disorders, and area of residence. The primary outcome was a composite of antidepressant discontinuation, switch to another antidepressant, and concomitant use of antidepressants. The secondary outcome was the resumption of antidepressant during follow-up. We used Cox marginal proportional hazards models to compare time to outcomes between pregnant and nonpregnant women. The pregnant cohort included 6593 women, and the comparison cohort 29,347 nonpregnant women. In the period following the first month of treatment, pregnant women were more likely to experience treatment modification, and especially to stop receiving it, compared with nonpregnant women (adjusted hazard ratio (aHR) 1.58; 95%CI, 1.51-1.62). Pregnant women who discontinued treatment had a 41% decreased incidence of antidepressant resumption compared with nonpregnant women (aHR 0.59; 95%CI, 0.56-0.62). Pregnancy was a determinant of antidepressant treatment modification, and especially of discontinuation.

Negative impact of maternal antenatal depressive symptoms on neonate's behavioral characteristics.

Prenatal maternal depression is associated with developmental disorders in offspring. However, the specific effects of the intensity of prenatal depressive symptoms on infant behavior remain poorly explored. The aim of this work is to explore the links between early neonatal behavior and maternal prenatal depressive symptoms, independently from maternal pre- and postnatal anxiety and early postnatal maternal depressive symptoms. Five hundred and ninety-eight women and their newborns from the MATQUID cohort were prospectively evaluated during the 8th month of pregnancy (T1) and at day 3 postpartum (T2). We analyzed the independent associations between neonates' behavior (Neonatal Behavioral Assessment Scale-NBAS) at T2 and the intensity of maternal prenatal depressive symptoms (CES-D), taking into account confounding factors including depressive symptoms at T2 and anxiety (T1 and T2). The presence of a major depressive episode (MDE) based on MINI at T1 was also studied, independently. Our results show a significant negative correlation between prenatal CES-D scores and NBAS scores on "habituation" (p = 0.0001), "orientation" (p = 0.015), "motor system" (p < 0.0001), "autonomic stability" (p < 0.0001) dimensions, independently of other variables, including pre/postnatal anxiety and postnatal depressive symptoms. A prenatal MDE was independently associated with lower scores on the "orientation" dimension (p = 0.005). This study reports a specific effect of prenatal depressive symptoms on newborn's behavior. These results highlight the crucial necessity for antenatal screening and adjusted treatments of maternal depressive symptoms and not only of MDE. Particular attention must be paid to infants of mothers presenting prenatal depressive symptoms to provide them with early developmental care when necessary.

Impact of a prenatal episode and diagnosis in women with serious mental illnesses on neonatal complications (prematurity, low birth weight, and hospitalization in neonatal intensive care units).

Pregnancy in women with mental disorders is increasingly common. The aim of this study was to determine, in women with severe mental illnesses, whether a prenatal episode was related to neonatal complications and if a specific disorder was associated with a higher risk. A population of infants and their mothers (n = 1439) jointly admitted to psychiatric Mother-Baby Units in France and Belgium (2001-2010) was assessed respectively for prematurity, low birth weight (LBW), hospitalization in neonatal intensive care units (NICUs), and maternal mental health during pregnancy. Logistic regression was used to explore the association between neonatal complications and a prenatal episode of mental illness and if the presence of a specific disorder was related to a higher risk, taking into account maternal socio-demographic characteristics, pregnancy data, and antenatal exposure to psychotropic drugs. Among the children, 145 (10.2%) were premature, 226 (15.8%) had a LBW, and 348 (24.3%) have been hospitalized in neonatology. The presence of an episode of mental illness during pregnancy was linked to LBW (OR = 2.21 [1.44-3.38]; p = 0.003) and NICU hospitalizations (OR = 1.53 [1.06-2.19], p = 0.002). Among diagnoses, the presence of a severe substance use disorder in these women was related to LBW (OR = 2.96 [1.49-5.85]; p = 0.002) and NICU (OR = 2.88 [1.56-5.29]; p = 0.04). Our results underline the importance of systematic and early detection of psychiatric symptoms and substance use disorders during pregnancy in preventing neonatal complications in women with serious mental illness.

Patterns of antidepressant use during pregnancy: a nationwide population-based cohort study.

AIMS: We explored the patterns of antidepressant use during pregnancy. METHODS: A cohort of women who started a pregnancy in 2014 was identified using data from the French reimbursement healthcare system (covering approximately 99% of the population). Antidepressant usage (initiated before or during pregnancy) was assessed. Explored changes in antidepressant treatment were: associations, switches, discontinuation and resumption of antidepressants during pregnancy. RESULTS: The cohort included 766 508 pregnancies (755 519 women). Antidepressant use during pregnancy was 25.7 per 1000 [95% CI: 25.3-26.0]. New use concerned 3.9 per 1000 [95% CI: 3.7-4.0]; the most initiated class during pregnancy was selective serotonin reuptake inhibitors (SSRIs), while the most prescribed individual drug in second and third trimesters was amitriptyline, a tricyclic. Most changes were observed before pregnancy and during the first trimester: 63% of ongoing treatments in the year before pregnancy were discontinued before conception; 68% of treatments maintained after conception were discontinued during the first trimester; switches or antidepressant associations mostly occurred during the periconceptional period or during the first trimester. Regardless of initial antidepressant, switches to sertraline were the most frequent. Associations mainly consisted of a prescription of tri-/tetracyclic or mirtazapine/mianserin in addition to an SSRI. Discontinuation during pregnancy led to treatment resumption in 22% of pregnancies. CONCLUSIONS: These results suggest that pregnancy was planned or the treatment especially adapted in accordance with existing recommendations in a large proportion of women under antidepressants or in whom such treatments have been initiated after starting a pregnancy.

Pregnancy in women with psychotic disorders: risk factors associated with mother-baby separation.

Pregnancy in women suffering from psychotic disorders is becoming more common. However, this psychiatric disorder is linked to the highest risk of early mother and child separation. The aim of this study was to evaluate risk factors associated with these separations. In an observational, naturalist, and multicentric study, 320 women suffering from a psychotic disorder and jointly hospitalized with their child in one of the sixteen mother-baby units (MBUs) in France and Belgium between 2001 and 2010 were assessed for risk factors associated with mother-child separation. Eighty-seven (27.2%) mothers were separated from their infant at discharge from MBUs. Early separation was linked to the placement of the mother herself in an institution in childhood (OR 4.44; CI 95% 1.12-18.69), to the mother being single (OR 3.84; CI 95% 1.38-11.44), to early hospitalization of the baby in neonatology (OR 2.88; CI 95% 1.27-6.59), and to maternal psychiatric decompensation during pregnancy (OR 2.60; CI 95% 1.15-6.20), independently from maternal neglectful behaviors. Low family/social support showed a trend towards association with separation (OR 2.17; CI 95% 0.91-5.42). This study shows that separation is mostly linked to mothers' environmental and interactive past and current history, to the child's health, and to maternal mental health decompensation. The identification of these factors is essential to implement antenatal prevention and social programs for these women. Further studies should focus on the long-term development of children of schizophrenic mothers, whether or not they have been placed, in order to help clarifying the impact of the risk factors.

Women's mental health in the perinatal period according to migrant status: the French representative ELFE birth cohort.

Background: Mental health problems in the perinatal period are common. We examined associations between different categories of migrant status and region of origin in relation to mental health during pregnancy and at 2 months post-partum. Methods: We analyzed data from the French nationally representative Etude Longitudinale Française depuis l'Enfance birth cohort (n = 17 988). Migrant status was divided into five categories: 'majority population', 'descendants with one migrant parent', 'descendants with two migrant parents', 'naturalized migrant' and 'non-naturalized migrant women'. Multivariate logistic regression models were implemented to examine associations between migrant status and mental health outcomes: persistent psychological difficulties during pregnancy as well as mother's depression and poor self-reported health at 2 months post-partum. Results: After adjusting for covariates, migrant status was not associated with psychological difficulties during pregnancy. Descendants of migrants had comparable mental health to the majority population. Non-naturalized migrant women were more likely to experience depression (odd's ratio (OR)= 1.66, 95%confidence interval (CI): 1.27, 2.20) and poor self-reported health (OR = 1.45, 95%CI: 1.06, 1.98) during the post-partum period. The region of origin was associated with post-partum health independently of migrant status, such that women from Africa and Turkey were most likely to have depression or poor self-rated health. Conclusion: First, but not second, generation migrant women appear to have high levels of mental health difficulties during the post-partum period. Women from North Africa, Sub-Saharan Africa, and Turkey have higher levels of distress than those from other regions. In particular, non-naturalized migrant appear to be a vulnerable group; they may disproportionately face stressors that increase their risk for post-partum depressive symptoms.

Timing and Chronicity of Maternal Depression Symptoms and Children's Verbal Abilities.

OBJECTIVE: To test the associations between the timing and chronicity of maternal depression symptoms (MDS) and children's long-term verbal abilities. STUDY DESIGN: Participants were 1073 mother-child pairs from a population-based birth cohort in Canada. MDS were assessed at ages 5 months, 1.5, 3.5, and 5 years using the Center for Epidemiologic Studies Depression Scale. Verbal abilities were measured at 5, 6, and 10 years using the Peabody Picture Vocabulary Test-Revised (PPVT-R). Multiple linear regression models were used to estimate the association between timing (early: 5 months and/or 1.5 years vs late 3.5 and/or 5 years) and chronicity (5 months, 1.5, 3.5, and 5 years) of exposure to elevated MDS and children's mean PPVT-R scores. RESULTS: Children exposed to chronic MDS had lower PPVT-R scores than children never exposed (mean difference = 9.04 [95% CI = 2.28-15.80]), exposed early (10.08 [3.33-16.86]) and exposed late (8.69 [1.85-15.53]). There were no significant differences between scores of children in the early compared with the late exposure group. We adjusted for mother-child interactions, family functioning, socioeconomic status, PPVT-R administration language, child's birth order, and maternal IQ, psychopathology, education, native language, age at birth of child, and parenting practices. Maternal IQ, (η2 = 0.028), native language (η2 = 0.009), and MDS (η2 = 0.007) were the main predictors of children's verbal abilities. CONCLUSIONS: Exposure to chronic MDS in early childhood is associated with lower levels of verbal abilities in middle childhood. Further research is needed in larger community samples to test the association between MDS and children's long-term language skills.

Smoking Trajectories during the Perinatal Period and Their Risk Factors: The Nationally Representative French ELFE (Etude Longitudinale Française Depuis l'Enfance) Birth Cohort Study.

BACKGROUND: In France, rates of perinatal smoking are among the highest worldwide; however, perinatal smoking trajectories and associated factors have still not been adequately researched. METHODS: Among women participating in the French nationally representative etude longitudinale française depuis l'enfance birth cohort (n = 15,540), perinatal smoking trajectories were estimated using group-based modelling. Associated characteristics were studied using multinomial logistic regression. RESULTS: Four trajectories were identified: non-smokers (59%), quitters (20%), persistent moderate (12%) and persistent heavy (9%) smokers. Older age, being native French, low socioeconomic position, persistent psychological difficulties and alcohol use in pregnancy, lack of social support, partner's smoking, mistimed pregnancy, and child formula feeding at birth were associated with persistent heavy smoking. Most of these factors were also associated, but to a lesser extent, with persistent moderate smoking, except for age and migrant status, which had opposite effects. Women who successfully lost weight prior to pregnancy had higher levels of quitting smoking. CONCLUSION: Women's long-term smoking trajectories vary in terms of initial tobacco consumption level but also in relation to socio-demographic, psychological, behavioral and partner characteristics. Health professionals in contact with pregnant smokers should address perceived risks and benefits of smoking, including partner's smoking and weight-gain concerns.

Maternal Depression Trajectories and Children's Behavior at Age 5 Years.

OBJECTIVE: To assess the relationship between trajectories of maternal depression from pregnancy to the child's age of 5 years and children's emotional and behavioral difficulties at age 5 years. STUDY DESIGN: Mother-child pairs (n = 1183) from the EDEN mother-child birth cohort study based in France were followed from 24 to 28 weeks of pregnancy to the child's fifth birthday. Children's behavior at age 5 years was assessed with the Strengths and Difficulties Questionnaire. Maternal depression was assessed repeatedly with the Center for Epidemiological Studies Depression questionnaire (pregnancy, 3, and 5 years of age) and the Edinburgh Postnatal Depression Scale (4, 8, and 12 months postpartum). Homogeneous latent trajectory groups of maternal depression were identified within the study population and correlated with Strengths and Difficulties Questionnaire scores by the use of multivariate linear regression analyzes. RESULTS: Five trajectories of maternal symptoms of depression were identified: no symptoms (62.0%); persistent intermediate-level depressive symptoms (25.3%); persistent high depressive symptoms (4.6%); high symptoms in pregnancy only (3.6%); and high symptoms in the child's preschool period only (4.6%). Children whose mothers had persistent depressive symptoms--either intermediate or high--had the greatest levels of emotional and behavioral difficulties at age 5 years. In addition, compared with children whose mothers were never depressed, those whose mothers had high symptoms in the preschool period also had increased levels of emotional symptoms, conduct problems, and peer problems. CONCLUSIONS: Maternal depression symptoms are related to children's emotional and behavioral problems, particularly if they are persistent (29.9%) or occur during early childhood (4.6%).

The stigma of smoking among women: A systematic review.

BACKGROUND: Smoking stigma has been well documented, but little is known regarding its specific features and effects on women. Notably, women face unique social, cultural, and economic challenges that may interact with smoking stigma and impact health outcomes. This review investigates the extent to which smoking women encounter and internalise stigma, while examining the various coping mechanisms they employ to manage these negative experiences. METHODS: In November 2022, major databases were systematically searched with no time restrictions. After applying inclusion and exclusion criteria, 23 studies (three quantitative and 20 qualitative) met our criteria. We conducted a quality assessment and summarised the findings pertaining to public stigma, self-stigma, and coping strategies. RESULTS: The stigma about smoking emerges from a variety of sources, such as family, healthcare providers, or internet forums. Women smokers are universally aware of the negative image they have in society. Yet, their experiences and management of the stigma of smoking are shaped by other variables such as cultural background, social class, or motherhood status. Smoking stigma produces ambivalent effects, such as concealment, reduced usage of support services, and to a lesser extent, smoking cessation motivation. CONCLUSIONS: These results indicate that smoking stigma is an important social justice and public health issue and that further research is needed to better prevent its effects on women's well-being and health behaviours.

Impact of paternal psychiatric disorders on parents-baby separation after mother-baby unit care.

BACKGROUND: Paternal mental health may have an impact on parenthood especially in case of maternal postpartum severe psychiatric illness. OBJECTIVE: The aim of this study was to search for an association between paternal psychiatric disorder and parents-baby separation after a maternal joint hospitalization for a severe postpartum psychiatric episode. PARTICIPANTS AND SETTINGS: In an observational, naturalist and multicentric study, 787 fathers whose partner was hospitalized in a mother-baby unit were included. METHODS: Fathers were assessed for psychiatric diagnoses associated with parents-baby separation. RESULTS: 25 % of the fathers had a psychiatric disorder. 69 babies (8.77 %) were separated from their parents at the end of the joint hospitalization. In multivariate analysis, parents-baby separation was associated with a paternal diagnosis of addictive disorder (OR = 8.35, 95 % CI [3.45-30.30]) and psychotic disorder (OR = 5.76, 95 % CI [1.97-16.78]), independently from potential confounding variables including maternal psychiatric diagnosis. CONCLUSIONS: This study shows the major impact of a paternal psychiatric disorder in the outcome of a joint hospitalization. A paternal mental illness should be systematically looked for in case of a severe maternal postpartum psychiatric episode, considering it is predictive of parenthood difficulties.

Cord serum cytokines at birth and children's trajectories of mood dysregulation symptoms from 3 to 8 years: The EDEN birth cohort.

There is growing evidence that in utero imbalance immune activity plays a role in the development of neurodevelopmental and psychiatric disorders in children. Mood dysregulation (MD) is a debilitating transnosographic syndrome whose underlying pathophysiological mechanisms could be revealed by studying its biomarkers using the Research Domain Criteria (RDoC) model. Our aim was to study the association between the network of cord serum cytokines, and mood dysregulation trajectories in offsprings between 3 and 8 years of age. We used the data of a study nested in the French birth cohort EDEN that took place from 2003 to 2014 and followed mother-child dyads from the second trimester of pregnancy until the children were 8 years of age. The 2002 mother-child dyads were recruited from the general population through their pregnancy follow-up in two French university hospitals. 871 of them were included in the nested cohort and cord serum cytokine levels were measured at birth. Children's mood dysregulation symptoms were assessed with the Strengths and Difficulties Questionnaire Dysregulation Profile at the ages 3, 5 and 8 years in order to model their mood dysregulation trajectories. Out of the 871 participating dyads, 53% of the children were male. 2.1% of the children presented a high mood dysregulation trajectory whereas the others were considered as physiological variations. We found a significant negative association between TNF-α cord serum levels and a high mood dysregulation trajectory when considering confounding factors such as maternal depression during pregnancy (adjusted Odds Ratio (aOR) = 0.35, 95% Confidence Interval (CI) [0.18-0.67]). Immune imbalance at birth could play a role in the onset of mood dysregulation symptoms. Our findings throw new light on putative immune mechanisms implicated in the development of mood dysregulation and should lead to future animal and epidemiological studies.

Predictors of infant foster care in cases of maternal psychiatric disorders.

PURPOSE: Our aim was to investigate the factors associated with mother-child separation at discharge, after joint hospitalization in psychiatric mother-baby units (MBUs) in France and Belgium. Because parents with postpartum psychiatric disorders are at risk of disturbed parent-infant interactions, their infants have an increased risk of an unstable early foundation. They may be particularly vulnerable to environmental stress and have a higher risk of developing some psychiatric disorders in adulthood. METHODS: This prospective longitudinal study of 1,018 women with postpartum psychiatric disorders, jointly admitted with their infant to 16 French and Belgian psychiatric mother-baby units (MBUs), used multifactorial logistic regression models to assess the risk factors for mother-child separation at discharge from MBUs. Those factors include some infant characteristics associated with personal vulnerability, parents' pathology and psychosocial context. RESULTS: Most children were discharged with their mothers, but 151 (15 %) were separated from their mothers at discharge. Risk factors independently associated with separation were: (1) neonatal or infant medical problems or complications; (2) maternal psychiatric disorder; (3) paternal psychiatric disorder; (4) maternal lack of good relationship with others; (5) mother receipt of disability benefits; (6) low social class. CONCLUSIONS: This study highlights the existence of factors other than maternal pathology that lead to decisions to separate mother and child for the child's protection in a population of mentally ill mothers jointly hospitalized with the baby in the postpartum period.
