Effects of perinatal mental disorders on the fetus and child

Introduction: Father-infant interactions are important for optimal offspring outcomes. Moreover, paternal perinatal psychopathology is associated with psychological and developmental disturbances in the offspring, and this risk may increase when both parents are unwell. While, the father-offspring relationship is a plausible mechanism of risk transmission, there is presently no “gold standard” tool for assessing the father-offspring relationship. Therefore, we systematically searched and reviewed the application and performance of tools used to assess the father-offspring relationship from pregnancy to 24-months postnatal.Methods: Four electronic databases (including MEDLINE, PsycINFO, Maternity and Infant Care Database, and CINAHL) were searched. Selected articles included evidence of father-offspring relationship assessment in relation to parental perinatal psychopathology and/or offspring outcomes. Data was extracted and synthesized according to the following: (i) evidence supporting the performance of tools in terms of their psychometric properties when applied in the context of fathers, (ii) tool specific characteristics, and (iii) study specific methodological aspects in which the tool was embedded.Results: Of the 30,500 records eligible for screening, 38 unique tools used to assess the father-offspring relationship were identified, from 61 studies. Ten tools were employed in the context of paternal psychopathology, three in the context of maternal psychopathology, and seven in the context of both maternal and paternal psychopathology, while nine tools were applied in the context of offspring outcomes only. The remaining nine tools were used in the context of both parental psychopathology (i.e., paternal, and/or maternal psychopathology) and offspring outcomes. Evidence supporting the psychometric robustness of the extracted observational, self-report and interview-based tools was generally limited. Most tools were originally developed in maternal samples—with few tools demonstrating evidence of content validation specific to fathers. Furthermore, various elements influencing tool performance were recognized—including variation in tool characteristics (e.g., relationship dimensions assessed, assessment mode, and scoring formats) and study specific methodological aspects, (e.g., setting and study design, sample characteristics, timing and nature of parental psychopathology, and offspring outcomes).Conclusion: Given the strengths and limitations of each mode of assessment, future studies may benefit from a multimethod approach to assessing the father-offspring relationship, which may provide a more accurate assessment than one method alone.

THE BURGEONING BURDEN OF PERINATAL MENTAL HEALTH IN LOWER MIDDLE-INCOME COUNTRIES

Considering Prenatal Alcohol Exposure in a Developmental Origins of Health and Disease Framework.

Perinatal (antenatal and postpartum) depression is increasingly becoming a global public health problem. Studies have shown that the presence of depression during the perinatal period impact on a mother's ability to adequately provide nutritional care for herself and her infants and young children. This may thus negatively influence the nutritional status of these vulnerable children resulting in poor growth, such as stunting which is currently a public health problem in low- and middle-income countries (LMICs). The aim of this systematic review and meta-analysis was to determine the association between maternal postpartum depression and child growth in LMICs. Electronic databases were systematically reviewed by screening abstracts, titles, full text and additional data sources of eligible papers. Articles were eligible for inclusion if based on children aged 0 to 59months, if reporting maternal postpartum depression as an exposure, if based on observational studies evaluating the relation between maternal postpartum depression and child growth, if reporting at least one physical growth indicator such as stunting as an outcome, and if published after 2000. Article selection was based on the PRISMA guidelines for reporting systematic reviews. Twelve articles were included in the quantitative synthesis (12 for stunting, 8 for underweight and 2 for wasting). Maternal postpartum depression was observed to be associated with an increased risk of child stunting (1.87 (95% CI: 1.52, 2.30; I2 = 41.6%, p = 0.064)) and underweight (1.81 (95% Cl: 1.25, 2.62; I2 = 70.7%, p = 0.001)). These results were confirmed after influence analyses, with publication bias being negligible. Conclusion: Maternal depression is a risk factor for poor child growth in LMICs. This study contributes to the knowledge on this topic and calls on policymakers to improve on its understanding, screening and treatment to alleviate the potential negative impact on child growth. What is Known: • Maternal postpartum depression is currently a public health relevance in low- and middle-income countries (LMICs). • Maternal postpartum depression is a risk factor for poor nutritional status in children from LMICs. What is New: • Maternal postpartum depression is associated with an 80 to 90% increased risk of childhood stunting and underweight in LMICs. • The association between risk of childhood stunting and underweight with maternal postpartum depression is slightly influenced by geographical area, rural or urban location, by factors such as study design, study quality and sample size.

14 - Psychotherapy for perinatal mental disorders in low- and middle-income countries

Epidemiology of maternal depression, risk factors, and child outcomes in low-income and middle-income countries

The authors examined the relationship between maternal depression, paternal psychopathology, and adolescent diagnostic outcomes in a community sample of 522 Australian families. They also examined whether chronic family stress, father's expressed emotion, and parents' marital satisfaction mediated the relationship between parental psychopathology and adolescent outcomes. Mother's education, child's gender, and family income were covaried in all analyses. Results revealed that maternal depression and paternal depression had an additive effect on youth externalizing disorders. In addition, maternal depression interacted with both paternal depression and paternal substance abuse in predicting youth depression but not youth nondepressive disorders. Chronic family stress and father's expressed emotion appeared to mediate the relationship between parental psychopathology and youth depression.

Maternal depression from the perinatal period onwards is a global health priority associated with an increased likelihood of suboptimal socio-developmental outcomes in offspring. An important aspect of this association is the extent to which sustained maternal depression impacts on these outcomes. The current review synthesised the evidence on maternal depression from the perinatal period onwards and offspring internalising, externalising, and social competence outcomes. We also identified sources of methodological bias. A systematic review following PRISMA guidelines was conducted. Longitudinal studies targeting biological mothers with depressive symptomology, detailing onset, using repeated validated measures, and assessing children's outcomes between three and 12 years were included. Twenty-four studies met inclusion criteria. Findings supported the validity of different presentations of maternal depression, including consistent identification of a group of chronically depressed mothers across countries. Mothers within this group reported poorer internalising, externalising, and social competence outcomes for their offspring, with the highest levels of child problems associated with greater maternal chronicity and symptom severity. Results differed by measurement type with mothers rating poorer outcomes in comparison to teachers reports. For timing of depression, evidence was inconsistent for independent effects of antenatal or postnatal depression on child outcomes. There was substantial variability in study quality assessment. Assessing different presentations of maternal depression is essential for capturing the longitudinal associations between maternal depression and offspring outcomes to inform targets of early intervention. Chronicity, severity, and concurrent maternal depression have important implications for children's development and should be targeted in future programme planning. Further research in low- and middle-income countries is warranted.

It is not known if parental psychiatric disorders have an independent effect on offspring smoking after controlling for genetic and environmental vulnerability to nicotine dependence. We tested if parental alcohol, drug, or conduct disorders; antisocial personality disorder; depression; and anxiety disorders remained significant predictors of offspring smoking initiation, regular smoking, and nicotine dependence before and after adjusting for genetic and environmental risk for nicotine dependence. Data were obtained via semi-structured interviews with 1,107 twin fathers, 1,919 offspring between the ages of 12 and 32, and 1,023 mothers. Genetic and environmental liability for smoking outcomes was defined by paternal and maternal nicotine dependence. Multinomial logistic regression models were computed to estimate the risk for offspring trying cigarettes, regular smoking, and the Fagerström Test for Nicotine Dependence (FTND) as a function of parental psychopathology and sociodemographics before and after adjusting for genetic and environmental vulnerability to nicotine dependence. Before adjusting for genetic and environmental risk for nicotine dependence, ever trying cigarettes was associated with maternal depression, regular smoking was associated with maternal alcohol dependence and maternal conduct disorder, and FTND was associated with paternal and maternal conduct disorder and antisocial personality disorder. No parental psychopathology remained significantly associated with regular smoking and FTND after adjusting for genetic and environmental vulnerability to nicotine dependence in a multivariate model. The association between parental psychopathology and offspring smoking outcomes is partly explained by genetic and environmental risk for nicotine dependence. Point estimates suggest a trend for an association between parental antisocial personality disorder and offspring regular smoking and nicotine dependence after adjusting for genetic and environmental vulnerability. Studies in larger samples are warranted.

SummaryBackgroundEvidence exists that maternal depression in the perinatal period has an adverse effect on a range of early childhood outcomes and increases the risk of offspring depression during adolescence. However, the association between maternal depression during the perinatal period and offspring psychotic experiences has not been investigated. We aimed to investigate whether there is an association between maternal antenatal or postnatal depression and offspring psychotic experiences at 18 years of age.MethodsThis longitudinal study used data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a prospective birth cohort, which recruited 14 541 pregnant women with an estimated delivery date between April 1, 1991, and Dec 31, 1992. Perinatal depression was measured using the Edinburgh Postnatal Depression Scale (EPDS); offspring psychotic experiences at 18 years of age were measured using the Psychosis-Like Symptom Interview. Offspring of mothers with complete data on maternal perinatal depression measures, and complete data on outcome (psychotic experiences) and confounding variables were included in the main analysis. For the main analysis, we used logistic regression to examine the associations between maternal depression (antenatal and postnatal) and offspring psychotic experiences at the age of 18 years. We used biprobit regression to model the association between maternal antenatal depression and the two offspring outcomes (psychotic experiences and depression) at 18 years of age jointly.Findings3067 offspring for whom data were available on maternal perinatal depression and offspring psychotic experiences aged 18 years were included in analyses. Maternal antenatal depressive symptoms were associated with offspring psychotic experiences at 18 years of age, with an unadjusted odds ratio (OR) of 1·38 (95% CI 1·18–1·61, p=0·0001) and after adjustment for confounders, an OR of 1·26 (1·06–1·49, p=0·0074). Maternal antenatal depressive symptoms were associated with both offspring psychotic experiences at the age of 18 years (n=2830, OR for a 5-point increase in EPDS score: 1·32 [95% CI 1·16–1·51], p<0·0001) and offspring depression at 18 years (OR for a 5-point increase in EPDS score: 1·18 [1·03–1·34], p=0·016). From joint modelling, there was no evidence that the association between maternal antenatal depression and offspring psychotic experiences differed in strength compared with offspring depression (p=0·19).InterpretationThe offspring of mothers who experience depression in the perinatal period are more likely to report psychotic experiences at 18 years of age. If the association is found to be causal, it would strengthen the case for identifying and treating maternal depression during and after pregnancy.FundingUK Medical Research Council and the Wellcome Trust.

Postnatal depression (PND) affects approximately 10-20% of new mothers in developed countries, with accumulating research documenting its adverse impact on not only the mother but also the wider family. Longitudinal studies assessing potential effects of maternal PND on offspring are mounting, and it is therefore timely to investigate the long-term psychological outcomes for adolescent offspring who were exposed to PND in infancy. PsycINFO, Medline, and Embase databases were searched with key terms for English language abstracts. Papers of 16 were identified that examined associations between PND and internalising problems, externalising problems, psychopathology, psychosocial, and cognitive outcomes of adolescent offspring. Impaired offspring cognitive outcomes reflected some of the most consistent findings. Conflicting evidence was found for an effect of PND on adolescent offspring internalising and externalising problems and overall psychopathology. Psychosocial outcomes in offspring adolescents indicated a specific adverse effect, although based on only two studies. Significant gender differences across outcomes were found. It was concluded that PND possibly increases risk vulnerability in the presence of recurrent, concurrent, and antenatal maternal depression but that these latter factors alone may be the stronger specific predictors. Limitations of the review are discussed as well as implications for future research and clinical practice.

Understanding differences in factors leading to positive outcomes in high-risk and low-risk offspring has important implications for preventive interventions. We identified variables predicting positive outcomes in a cohort of 235 offspring from 76 families in which one, both, or neither parent had major depressive disorder. Positive outcomes were termed resilient in offspring of depressed parents, and competent in offspring of non-depressed parents, and defined by two separate criteria: absence of psychiatric diagnosis and consistently high functioning at 2, 10, and 20 years follow-up. In offspring of depressed parents, easier temperament and higher self-esteem were associated with greater odds of resilient outcome defined by absence of diagnosis. Lower maternal overprotection, greater offspring self-esteem, and higher IQ were associated with greater odds of resilient outcome defined by consistently high functioning. Multivariate analysis indicated that resilient outcome defined by absence of diagnosis was best predicted by offspring self-esteem; resilient outcome defined by functioning was best predicted by maternal overprotection and self-esteem. Among offspring of non-depressed parents, greater family cohesion, easier temperament and higher self-esteem were associated with greater odds of offspring competent outcome defined by absence of diagnosis. Higher maternal affection and greater offspring self-esteem were associated with greater odds of competent outcome, defined by consistently high functioning. Multivariate analysis for each criterion indicated that competent outcome was best predicted by offspring self-esteem. As the most robust predictor of positive outcomes in offspring of depressed and non-depressed parents, self-esteem is an important target for youth preventive interventions.
