  • GRIN2B predicts attention problems among disadvantaged children
    • Abstract: Abstract It is well established that adversities and GRIN2B (coding an N-methyl-d-aspartate receptor subunit) are independently associated with behavioral and cognitive impairments in childhood. However, a high proportion of children exposed to adversities have good, long-term outcomes. We hypothesized that among children exposed to adversities, GRIN2B variants would predict the worst cognitive and behavioral outcomes. 6 single nucleotide polymorphisms of GRIN2B were genotyped in 625 children aged 6–11 years from an Italian community-based sample. The interacting effect of GRIN2B variants with 4 measures of adversities [low socioeconomic status (SES), preterm delivery, maternal smoking during pregnancy, and absence of breastfeeding] was investigated upon blindly assessed cognitive abilities (vocabulary, block design, digit spans of Wechsler’s Intelligence Scale, and Rey complex figure) and parents-rated behavioral problems (Child Behavior Checklist/6–18). Rs2268119 × SES interaction (Hotelling’s Trace = 0.07; F(12,1154) = 3.53; p = 0.00004) influenced behavior, with more attention problems among children in the ‘either A/T or T/T genotype and low SES’ group, compared to all other groups. This interaction effect was not significant in an independent, replication sample of 475 subjects from an Italian community-based sample. GRIN2B variants predict children with the worst outcome in attention functioning among children exposed to low SES. Our findings, if replicated, could help in the identification of children with the highest risk and may prompt cost-effective preventive/treatment strategies.

  • Childhood friendships and psychological difficulties in young adulthood:
           an 18-year follow-up study
    • Abstract: Abstract Childhood friendships have been shown to impact mental health over the short term; however, it is unclear whether these effects are sustained into young adulthood. We studied the prospective association between childhood friendships and psychological difficulties in young adulthood. Data come from 1,103 French 22–35 year olds participating in the TEMPO study. Childhood friendships were ascertained in 1991 when participants were 4–16 years old. Psychological difficulties were measured in 2009 using the Adult Self-Report. Logistic regression models controlled for participants’ age, sex, childhood psychological difficulties and parental characteristics. Young adults who had no childhood friends had higher odds of psychological difficulties than those with at least one friend: (adjusted ORs 2.45; 95 % CI 1.32–4.66, p = 0.01 for high internalizing symptoms; 1.81; 95 % CI 0.94–3.54, p = 0.08 for high externalizing symptoms). Social relations early in life may have consequences for adult psychological well-being.

  • Development of children born to mothers with mental health problems:
           subcortical volumes and cognitive performance at 4½ years
    • Abstract: In a prospective longitudinal study, we investigated the outcomes of children born to mothers clinically referred for mental health problems during pregnancy (risk group, n = 17) relative to a control group (n = 31). Child cognitive functioning, and for subgroups (n = 10 + 17), brain morphometry as derived from Magnetic resonance imaging (MRI), was measured at 4½ years. Cognitive data included abstract visuospatial reasoning/problem solving and verbal scores. Subcortical regions of interest included the amygdala, accumbens area, hippocampus, caudate and putamen, chosen because their development seems potentially sensitive to an adverse intrauterine milieu and environmental experiences, and also due to their implication in cognitive and emotional processes. The risk group exhibited poorer abstract reasoning scores than the control group. No differences were found for verbal scores. MRI revealed smaller putamen volume in children in the risk group. Irrespective of group, putamen volume was positively related to visuospatial reasoning performance. Our results suggest that maternal psychopathology may be associated with child putamen development, nonverbal reasoning and problem solving skills.

  • Minor neurodevelopmental impairments are associated with increased
           occurrence of ADHD symptoms in children born extremely preterm
    • Abstract: Abstract ADHD is more common in children born preterm than at term. The purpose of the study was to examine if, and to what extent, ADHD symptoms are associated with minor neurodevelopmental impairments (NDI) in extremely preterm children. In a national population-based cohort with gestational age 22–27 weeks or birth weight <1,000 g assessed at 5 years of age, scores on Yale Children’s Inventory (YCI) scales (seven scales) were related to normal functions vs. NDI defined as mild impairments in cognitive function (IQ 70–84), motor function (Movement Assessment Battery for children score > the 95th percentile or freely ambulatory cerebral palsy), vision (correctable), and hearing (no hearing aid). YCI was completed for 213 of 258 eligible children (83 %). Children with minor NDIs (n = 98) had significantly higher scores (more ADHD symptoms) than those without NDI (n = 115) on the YCI scales of Attention, Tractability, Adaptability and Total score. Increasing numbers of minor NDIs were associated with higher mean YCI scores. In multivariate analysis only decreased hearing, IQ, and male gender were significantly associated with scores on the Attention scale. Thirty-three children (16 %) had scores >3 on the Attention scale (probably ADHD), and the proportion was significantly higher for those with mild NDIs compared to those without (Odds ratio = 2.7, 95 % CI 1.3–6.0). Children born extremely preterm with minor NDIs were more likely to have ADHD symptoms than those with no NDI, and increasing number of minor NDIs were associated with more ADHD symptoms.

  • Emotional and behavioural resilience to multiple risk exposure in early
           life: the role of parenting
    • Abstract: Abstract Ecological and transactional theories link child outcomes to neighbourhood disadvantage, family poverty and adverse life events. Traditionally, these three types of risk factors have been examined independently of one another or combined into one cumulative risk index. The first approach results in poor prediction of child outcomes, and the second is not well rooted in ecological theory as it does not consider that distal risk factors (such as poverty) may indirectly impact children through proximal risk factors (such as adverse life events). In this study, we modelled simultaneously the longitudinal effects of these three risk factors on children’s internalising and externalising problems, exploring the role of parenting in moderating these effects. Our sample followed 16,916 children (at ages 3, 5 and 7 years; N = 16,916; 49 % girls) from the UK Millennium Cohort Study. Parenting was characterised by quality of parent–child relationship, parental involvement in learning and parental discipline. Neighbourhood disadvantage, family poverty and adverse events were all simultaneously related to the trajectories of both outcomes. As expected, parenting moderated risk effects. Positive parent–child relationship, rather than greater involvement or authoritative discipline, most consistently ‘buffered’ risk effects. These findings suggest that a good parent–child relationship may promote young children’s emotional and behavioural resilience to different types of environmental risk.

  • Early-onset restrictive eating disturbances in primary school boys and
           girls
    • Abstract: Abstract This study sought to determine the distribution of early-onset restrictive eating disturbances characteristic of the new DSM-5 diagnosis, avoidant/restrictive food intake disorder (ARFID) in middle childhood, as well as to evaluate the screening instrument, Eating Disturbances in Youth-Questionnaire (EDY-Q). A total of 1,444 8- to 13-year-old children were screened in regular schools (3rd to 6th grade) in Switzerland using the self-report measure EDY-Q, consisting of 12 items based on the DSM-5 criteria for ARFID. 46 children (3.2 %) reported features of ARFID in the self-rating. Group differences were found for body mass index, with underweight children reporting features of ARFID more often than normal and overweight children. The EDY-Q revealed good psychometric properties, including adequate discriminant and convergent validity. Early-onset restrictive eating disturbances are commonly reported in middle childhood. Because of possible negative short- and long-term impact, early detection is essential. Further studies with structured interviews and parent reports are needed to confirm this study’s findings.

  • Behavioural and emotional problems in moderately preterm children with low
           socioeconomic status: a population-based study
    • Abstract: Abstract Moderately preterm (MP) birth is associated with higher rates of behavioural and emotional problems. To determine the extent to which low socioeconomic status (SES) contributes to these higher rates, we assessed independent and joint effects of MP birth and low SES, overall and by gender. Dutch preventive child health care centres provided a population-based sample of 915 MP children (32–36 weeks gestation) and 543 term-born children, born in 2002/2003. In multivariable logistic regression analyses, we determined the risk of behavioural and emotional problems per standard deviation (SD) decrease in gestational age and SES, using standardized measures for both. We also assessed three SES categories, being low (1SD or more below mean of standardized SES), intermediate (mean ± 1SD), and high (greater than mean + 1SD). The Child Behavior Checklist for 1.5–5 years was used to assess behavioural (externalizing), emotional (internalizing), and total problems at age 4 years. MP children with low SES had significantly higher total problem scores than those with high SES (11.3 vs. 5.1 %, respectively). Each SD decrease in SES was associated with a 42 % higher odds of elevated total problem scores (OR 1.42, 95 % CI 1.14–1.77). No joint effects were found, meaning that lower gestational age independently added to the risk of behaviour problems (OR 1.24, 95 % CI 1.00–1.56). Effects of MP birth and low SES were more pronounced in girls. In conclusion, MP birth and low SES multiply the risk of behavioural and emotional problems. The combination of risk factors identifies children who could benefit greatly from early intervention.

  • Maternal pre-pregnancy risk drinking and toddler behavior problems: the
           Norwegian Mother and Child Cohort Study
    • Abstract: Abstract Maternal risk drinking may be a risk factor for child behavior problems even if the mother has discontinued this behavior. Whether pre-pregnancy risk drinking is an independent predictor of child behavior problems, or whether a potential effect may be explained by maternal alcohol use during and after pregnancy or other adverse maternal characteristics, is not known. Employing data from the Norwegian Mother and Child Cohort Study (MoBa), longitudinal associations between maternal pre-pregnancy risk drinking and behavior problems in toddlers aged 18 and 36 months were examined. Included in the study was mothers answering MoBa questionnaires when the child was 18 (N = 56,682) and 36 months (N = 46,756), and who had responded to questions regarding pre-pregnancy risk drinking at gestation week 17/18, using the screening instrument T-ACE. Toddler behavior problems were measured with items from Child Behavior Checklist. Associations were analyzed with multivariate logistic regression, controlling for pre and postnatal alcohol use, as well as other relevant covariates. Pre-pregnancy risk drinking was associated with child behavior problems at 18 and 36 months, even after controlling for pre and postnatal alcohol use. Maternal ADHD and anxiety and depression were the only covariates that had any substantial impact on the associations. When all covariates were included in the model, the associations were weak for internalizing behavior problems and non-significant for externalizing behavior problems. Pre-pregnancy risk drinking may predict early development of behavior problems in the offspring. This increased risk may be due to other adverse maternal characteristics associated with risk drinking, in particular co-occurring maternal psychopathology.

  • Identifying maternal risk factors associated with Fetal Alcohol Spectrum
           Disorders: a systematic review
    • Abstract: Abstract To identify the demographic, psychological, and social maternal risk factors associated with the development of Fetal Alcohol Spectrum Disorders (FASD). A bibliographic search was conducted in PubMed, SciELO, Lilacs, Web of Knowledge, and PsycINFO. The Newcastle–Ottawa Quality Assessment Scale (NOS) was used to evaluate the quality of the studies with case–control design. Articles were selected based on their relevance and presentation of data related to statistical comparisons of at least one or more demographic, psychological, or social maternal risk factors for FASD. 738 references were identified, of which 15 met the criteria to be included in the present review. Mothers of FASD children tend to: be older at the time of birth of the affected child, present lower educational level, have other family relatives with alcohol abuse, have other children with FASD, present a pattern of little prenatal care and a distinguishing pattern of alcohol consumption (alcohol use before and during pregnancy, failure to reduce alcohol use during pregnancy, and frequent episodes of binge drinking). Application of the NOS scale of methodological quality indicated that 8 studies (53 %) met the criterion for selection, 4 (27 %) were suitable for the criterion for comparability and only 4 studies were suitable for the exposition criterion. Mothers of FASD children have a distinctive pattern of drinking and accumulate several social risk factors. Maternal age at birth of the child seems to accentuate the risk. There are, however, few controlled studies that are adequate according to the NOS requirements for methodological quality. Fewer are based on the verification of a theoretical model. Clinicians should be aware of the relevance of preventive assessment of FASD risk mothers.

  • Mechanisms underlying the effects of prenatal psychosocial stress on child
           outcomes: beyond the HPA axis
    • Abstract: Abstract Accumulating evidence from preclinical and clinical studies indicates that maternal psychosocial stress and anxiety during pregnancy adversely affect child outcomes. However, knowledge on the possible mechanisms underlying these relations is limited. In the present paper, we review the most often proposed mechanism, namely that involving the HPA axis and cortisol, as well as other less well-studied but possibly relevant and complementary mechanisms. We present evidence for a role of the following mechanisms: compromised placental functioning, including the 11β-HSD2 enzyme, increased catecholamines, compromised maternal immune system and intestinal microbiota, and altered health behaviors including eating, sleep, and exercise. The roles of (epi)genetics, the postnatal environment and the fetus are also discussed. We conclude that maternal prenatal psychosocial stress is a complex phenomenon that affects maternal emotions, behavior and physiology in many ways, and may influence the physiology and functioning of the fetus through a network of different pathways. The review concludes with recommendations for future research that helps our understanding of the mechanisms by which maternal prenatal stress exerts its effect on the fetus.

  • Does paternal mental health in pregnancy predict physically aggressive
           behavior in children'
    • Abstract: Abstract The aim was to study the association between paternal mental health and physically aggressive behavior in children. This study is based on 19,580 father–child dyads from the Norwegian Mother and Child Cohort Study (MoBa). Fathers’ mental health was assessed by self-report (Symptom Checklist-5, SCL-5) in week 17 or 18 of gestation. Children’s behavior (hitting others) was obtained by mothers’ reports. A multinomial logistic regression model was performed. Expectant fathers’ high level of psychological distress was found to be a significant risk factor only for girls hitting, adjusted OR = 1.46 (1.01–2.12), p = 0.043, but not for boys. High levels of mental distress in fathers predict their daughters’ hitting at 5 years of age.

  • Neuronal substrates and functional consequences of prenatal cannabis
           exposure
    • Abstract: Abstract Cannabis remains one of the world’s most widely used substance of abuse amongst pregnant women. Trends of the last 50 years show an increase in popularity in child-bearing women together with a constant increase in cannabis potency. In addition, potent herbal “legal” highs containing synthetic cannabinoids that mimic the effects of cannabis with unknown pharmacological and toxicological effects have gained rapid popularity amongst young adults. Despite the surge in cannabis use during pregnancy, little is known about the neurobiological and psychological consequences in the exposed offspring. In this review, we emphasize the importance of maternal programming, defined as the intrauterine presentation of maternal stimuli to the foetus, in neurodevelopment. In particular, we focus on cannabis-mediated maternal adverse effects, resulting in direct central nervous system alteration or sensitization to late-onset chronic and neuropsychiatric disorders. We compare clinical and preclinical experimental studies on the effects of foetal cannabis exposure until early adulthood, to stress the importance of animal models that permit the fine control of environmental variables and allow the dissection of cannabis-mediated molecular cascades in the developing central nervous system. In sum, we conclude that preclinical experimental models confirm clinical studies and that cannabis exposure evokes significant molecular modifications to neurodevelopmental programs leading to neurophysiological and behavioural abnormalities.

  • Antenatal depression and children’s developmental outcomes:
           potential mechanisms and treatment options
    • Abstract: Abstract During the last decade there has been increased recognition of the prevalence of antenatal depression as well as an expansion in research examining the impact of maternal mood during pregnancy on offspring development. The aim of this review was to summarise the theoretical underpinnings and empirical evidence regarding the impact of antenatal depression on children’s developmental outcomes. Biological mechanisms hypothesised to account for an association between antenatal depression and adverse offspring outcomes are first identified including the functioning of the prenatal Hypothalamic Pituitary Adrenal (HPA) axis and epigenetic processes. A systematic literature search is then conducted of studies examining the impact of antenatal depression on child development. In general, studies examining associations between antenatal depression and offspring temperament, cognitive and emotional outcomes reveal either no effect of the prenatal environment or small effects that often attenuate following adjustment for other antenatal and postnatal risk factors. In contrast, an independent effect of antenatal depression on children’s conduct problems and antisocial behaviour is a well-replicated finding. There is emerging evidence that exposure to depression during pregnancy impacts negatively on offspring biology, although the findings are complex and require replication. Psychological and pharmacological treatments of antenatal depression are then reviewed, considering whether antidepressant medication exerts harmful effects on the foetus. We close by proposing that antenatal depression is an early marker of a developmental cascade to future mental health problems for both mothers and offspring.

  • Maternal use of antidepressant or anxiolytic medication during pregnancy
           and childhood neurodevelopmental outcomes: a systematic review
    • Abstract: Abstract Antidepressant and anxiolytic medications are widely prescribed and used by pregnant women for acute and maintenance therapy. These drugs are able to pass the placental barrier, and may potentially influence fetal and brain development. It is possible that exposure to prenatal antidepressants or anxiolytic medication may disturb neurotransmitter systems in the brain and have long-lasting consequences on neurodevelopment in the offspring. As all medication during pregnancy may pose a certain risk to the developing fetus, the potential benefits of the medication must be weighed against the risks for both mother and her unborn child. Therefore, information to guide patients and physicians to make a well-balanced decision for the appropriate treatment during pregnancy is needed. In this systematic review, an overview of maternal use of antidepressant or anxiolytic medication during pregnancy and childhood neurodevelopmental outcomes is provided. Some studies indicate a relation between prenatal exposure to antidepressants and adverse neurodevelopmental outcomes such as delayed motor development/motor control, social difficulties, internalizing problems and autism, but cannot rule out confounding by indication. Overall, the results of the observational studies have been inconsistent, which makes translation of the findings into clinical recommendations difficult. More well-designed observational studies and also randomized controlled trials (e.g., maintenance treatment vs. cessation) are needed to move forward and provide a comprehensive evaluation of the risks and benefits of antidepressant and anxiolytic use during pregnancy.

  • Fetal alcohol spectrum disorders
    • Abstract: Abstract Prenatal alcohol exposure (PAE) is one of the most prevalent and modifiable risk factors for somatic, behavioral, and neurological abnormalities. Affected individuals exhibit a wide range of such features referred to as fetal alcohol spectrum disorders (FASD). These are characterized by a more or less specific pattern of minor facial dysmorphic features, growth deficiency and central nervous system symptoms. Nevertheless, whereas the diagnosis of the full-blown fetal alcohol syndrome does not pose a major challenge, only a tentative diagnosis of FASD can be reached if only mild features are present and/or maternal alcohol consumption during pregnancy cannot be verified. The respective disorders have lifelong implications. The teratogenic mechanisms induced by PAE can lead to various additional somatic findings and structural abnormalities of cerebrum and cerebellum. At the functional level, cognition, motor coordination, attention, language development, executive functions, memory, social perception and emotion processing are impaired to a variable extent. The long-term development is characterized by disruption and failure in many domains; an age-adequate independency is frequently not achieved. In addition to primary prevention, individual therapeutic interventions and tertiary prevention are warranted; provision of extensive education to affected subjects and their caregivers is crucial. Protective environments are often required to prevent negative consequences such as delinquency, indebtedness or experience of physical/sexual abuse.

  • Child maltreatment and psychological symptoms in a Portuguese adult
           community sample: the harmful effects of emotional abuse
    • Abstract: Child maltreatment (CM) is associated with poor long-term health outcomes. However, knowledge about CM prevalence and related consequences is scarce among adults in South European countries. We examined the self-reported prevalence of five different forms of CM in a community sample of 1,200 Portuguese adults; we compared the results with similar samples from three other countries, using the same instrument. We also explored the relationship between CM and psychological symptoms. Cross-sectional data using the Childhood Trauma Questionnaire-Short Form and the Brief Symptom Inventory were analyzed. Moderate or severe CM exposure was self-reported by 14.7 % of the sample, and 67 % was exposed to more than one form of CM. Emotional neglect was the most endorsed experience, with women reporting greater emotional abuse and men reporting larger physical abuse. Physical and sexual abuse was less self-reported by Portuguese than by American or German subjects. CM exposure predicted 12.8 % of the psychological distress. Emotional abuse was the strongest predictor for psychological symptoms, namely for paranoid ideation, depression, and interpersonal sensitivity. Emotional abuse overlapped with the exposure to all other CM forms, and interacted with physical abuse, physical neglect, and emotional neglect to predict psychological distress. Low exposure to emotional abuse was directly associated with the effects of physical abuse, physical neglect, and emotional neglect to predict adult psychological distress. Verbal abuse experiences were frequently reported and had the highest correlations with adult psychological distress. Our results underline the potential hurtful effects of child emotional abuse among Portuguese adults in the community. They also highlight the need to improve prevention and intervention actions to reduce exposure and consequences of CM, particularly emotional abuse.

  • Prenatal nicotine exposure and child behavioural problems
    • Abstract: Abstract In utero exposure to tobacco smoke has been related to numerous adverse health effects in new-borns, infants, children, adolescents and adults. The aim of this review was to summarise findings on prenatal nicotine exposure and its relationship with behavioural problems in the offspring. The majority of studies, and especially several recent epidemiological studies, observed a higher likelihood for attention-deficit/hyperactivity disorder (ADHD) or ADHD symptoms in exposed subjects. However, both human and animal studies have failed to provide clear evidence on causality. Existing literature on studies investigating the association between prenatal nicotine exposure and conduct or externalising problems in the offspring suggests a causal effect. The establishment of a final conclusion concerning the relationship between prenatal nicotine exposure and internalising problems in the offspring is complicated by insufficient data and mixed results in epidemiological studies. Prenatal nicotine exposure has been associated with altered brain structure and function in human offspring, and a proposed biological mechanism is related to nicotine’s adverse influence on neurotransmitter systems during brain development. In conclusion, establishing a statement on the causality of the relationship between prenatal nicotine exposure and behavioural problems in children remains a challenging task. Nevertheless, considering the results of an increasing number of studies which link prenatal exposure to nicotine to externalising problems applying different methodologies to account for confounding and in view of other adverse health effects known to be caused by this exposure, parents should consider smoking cessation.

  • Prenatal exposure to binge pattern of alcohol consumption: mental health
           and learning outcomes at age 11
    • Abstract: Abstract The objective of the study is to investigate whether episodic binge pattern of alcohol consumption during pregnancy is independently associated with child mental health and academic outcomes. Using data from the prospective, population-based Avon Longitudinal Study of Parents and Children (ALSPAC), we investigated the associations between binge patterns of alcohol consumption during pregnancy (≥4 drinks per day) and child mental health [as rated by both parent (n = 4,610) and teacher (n = 4,274)] and academic outcomes [based on examination results (n = 6,939)] at age 11 years. After adjusting for prenatal and postnatal risk factors, binge pattern of alcohol consumption (≥4 drinks in a day on at least one occasion) during pregnancy was associated with higher levels of mental health problems (especially hyperactivity/inattention) in girls at age 11 years, according to parental report. After disentangling binge-pattern and daily drinking, binge-pattern drinking was independently associated with teacher-rated hyperactivity/inattention and lower academic scores in both genders. Episodic drinking involving ≥4 drinks per day during pregnancy may increase risk for child mental health problems and lower academic attainment even if daily average levels of alcohol consumption are low. Episodic binge pattern of drinking appears to be a risk factor for these outcomes, especially hyperactivity and inattention problems, in the absence of daily drinking.
