Prenatal Alcohol Exposure, FASD, and Child Behavior: A Meta-analysis

Aboriginal Community Controlled Organisations Leading the Way in Child Health Research

Historically, Aboriginal and Torres Strait Islander research in Australia has adhered to Western research paradigms and contributed to the adverse impacts of colonisation. However, recent developments driven by Aboriginal and Torres Strait Islander people and scholars, and development of ethical guidelines for research, have promoted a more inclusive and collaborative research landscape. In this study, published papers and internal documents arising from a long-term partnership between Marninwarntikura Women's Resource Centre (MWRC) and the University of Sydney (USYD) from 2009 to 2023 were analysed using the Aboriginal and Torres Strait Islander Quality Appraisal Tool and consultations with project partners. Every project had Aboriginal and Torres Strait Islander governance, leadership, and inclusive consultation; was driven by community-identified priorities, built local capacity, and benefitted the community. There was an increase in the use of Indigenous research paradigms and data/intellectual property (IP) agreements over time, reflecting responsiveness to community leadership. This partnership exemplifies community-driven, co-designed, Aboriginal-led health research and serves as a model for effective collaboration with Aboriginal and Torres Strait Islander communities.

Screening and early intervention for substance use during pregnancy: A retrospective case note review of antenatal care records

INTRODUCTION

Screening for substance use during pregnancy is critical for enhancing maternal health and perinatal outcomes. However, disparities persist in screening and intervention rates within maternity services. This retrospective case note review explored contemporaneous practices around screening and interventions for substance use among pregnant women during routine antenatal care.

METHODS

A random sample of 100 sets of maternity records were reviewed. Eligible cases included any woman attending initial pregnancy assessments at one of two South Australian metropolitan Hospital-based antenatal clinics, from July 2019-September 2020. Screening rates for past and current alcohol, tobacco and other substance use were identified and compared with data from a subset of a nationally representative survey. Intervention details and referral pathways were also assessed.

RESULTS

The final sample of eligible cases (n = 93) demonstrated prioritisation of screening for current use, over past use, across all substances (p < 0.001). Screening was most likely for tobacco and least likely for e-cigarettes (p < 0.001). Significant underreporting of past use compared with the benchmark was identified for all substances (except tobacco, p = 0.224). Interventions typically involved written resources, which were usually declined by clients.

DISCUSSION AND CONCLUSIONS

Despite longstanding recommendations, screening and intervention practices for substance use appear inconsistent. With the recent emergence of vaping, no evidence of updated approaches to identifying e-cigarette consumption in pregnant women was found. Several opportunities for enhancing routine screening and intervention practices within antenatal clinics were identified, and will inform the development of policy directives, targeted training modules, and other resources for health professionals working in these services.

Using umbilical cord tissue to identify prenatal ethanol exposure and co-exposure to other commonly misused substances

OBJECTIVE

Substance misuse during pregnancy can result in a variety of poor pregnancy outcomes. Objective data reporting the prevalence of neonates born with ethanol metabolites (evidence of prenatal ethanol exposure) in their fluids or tissues are limited.

STUDY DESIGN

A secondary analysis of umbilical cord tissue specimens received for routine toxicological analysis was conducted. Prevalences of ethyl glucuronide (EtG), a long-term direct ethanol biomarker, were determined using a new laboratory tool, LDTD-MSMS. Additionally, other commonly misused substances were determined using routine procedures.

RESULTS

Of 12,995 specimens, 238 (1.8%) specimens contained EtG. Concentrations of EtG ranged from 5 ng/g to 6679 ng/g (median 47 ng/mg; IQR: 16 ng/g, 203 ng/g). Of those 238 EtG-positive specimens, nearly 58% (N = 138) contained additional substances or metabolites.

CONCLUSION

Self-report of substance use during pregnancy is under-reported. We have demonstrated co-exposure of substances with ethanol is higher than previous reports.

Questioning cognitive heterogeneity and intellectual functioning in fetal alcohol spectrum disorders from the Wechsler Intelligence Scale for Children

Introduction: Fetal Alcohol Spectrum Disorders (FASD) are characterized by a variety of multiple cognitive and behavioral impairments, with intellectual, attentional, and executive impairments being the most commonly reported. In populations with multiple neurodevelopmental disorders, the Full Scale Intelligence Quotient (FSIQ) may not be a proper measure of intellectual abilities, rarely interpreted in FASD clinical practice because the heterogeneity of the cognitive profile is deemed too strong. We propose a quantitative characterization of this heterogeneity, of the strengths and weaknesses profile, and a differential analysis between global cognitive (FSIQ) and elementary reasoning abilities in a large retrospective monocentric FASD sample. Methods: Using clinical and cognitive data (Wechsler Intelligence Scale for Children) from 107 children with FASD, we characterized subject heterogeneity (variance and scatter of scaled/composite scores), searched for strengths and weaknesses, and specified intellectual functioning in terms of FSIQ and elementary reasoning (General Abilities Index, Highest Reasoning Scaled Score), in comparison with standardization norms and a Monte-Carlo-simulated sample from normalization data. Results: Performance of children with FASD was lower on all subtests, with a significant weakness in working memory and processing speed. We found no increase in the variance and scatter of the scores, but a discordance between the assessment of global cognitive functioning (28% borderline, 23% deficient) and that of global and elementary reasoning abilities (23-9% borderline, 15-14% deficient). Conclusion: Our results question the notion of WISC profile heterogeneity in FASD and point to working memory and processing speed over-impairment, with global repercussions but most often preserved elementary reasoning abilities.

Neonatal outcomes of pregnant women attending integrated and standard substance use treatment programs in Ontario, Canada

BACKGROUND

Substance use in pregnancy raises concern given its potential teratogenic effects. Given the unique needs of parenting people and the potential impact for developing children, specialized substance use treatment programs are increasingly being implemented for this population. Substance use treatment is associated with more positive neonatal outcomes compared with no treatment, however treatment models vary limiting our understanding of key treatment components/modelsFew studies have explored the influence of treatment model type (i.e., integrated treatments designed for pregnant clients compared with standard treatment models) and no studies have examined the influence of treatment model on neonatal outcomes using Canadian data.

METHOD

We conducted a population-based cohort study of clients who were pregnant when initiating integrated (n = 564) and standard (n = 320) substance use treatment programs in Ontario, Canada.

RESULTS

Neonatal outcomes did not significantly differ by treatment type (integrated or standard), with rates of adverse neonatal outcomes higher than published rates for the general population, despite receipt of adequate levels of prenatal care. While this suggests no significant impact of treatment, it is notable that as a group, clients engaged in integrated treatment presented with more risk factors for adverse neonatal outcomes than those in standard treatment. While we controlled for these risks in our analyses, this may have obscured their influence in relation to treatment type.

CONCLUSION

Findings underscore the need for more nuanced research that considers the influence of client factors in interaction with treatment type. Pregnant clients engaged in any form of substance use treatment are at higher risk of having children who experience adverse neonatal outcomes. This underscores the urgent need for further investment in services and research to support maternal and neonatal health before and during pregnancy, as well as long-term service models that support women and children beyond the perinatal and early childhood periods.

Effectiveness of interventions for school-aged-children and adolescents with fetal alcohol spectrum disorder: a systematic review and meta-analysis

PURPOSE

To describe allied health and educational interventions and their effectiveness for children and adolescents with fetal alcohol spectrum disorder (FASD). To appraise the quality and strength of studies.

METHODS

Electronic databases were searched between 2005 and March 2022, identifying non-pharmacological studies supporting function, activity, or participation for FASD participants aged 5-18 years using any quantitative research design. Outcomes were coded using International Classification of Functioning, Disability and Health, family of Participation Related Constructs and behaviour categories. Multi-level random-effects meta-analysis examined intervention effects. Study methodological quality was evaluated using Cochrane risk of bias tools, RoBiNT, AMSTAR 2 and NHMRC Hierarchy levels of evidence. Certainty of findings were synthesised using GRADE approach.

RESULTS

The systematic review included 25 studies with 735 participants, 10 of which were analysed by meta-analysis. Body function and structure, activity, behaviour, and sense of self outcomes were pooled. A small, positive effect favouring interventions was found (g = 0.29, 95% CI = 0.15-0.43), however the GRADE certainty was rated as low. No participation outcomes were identified.

CONCLUSIONS

Some interventions targeting body function and structure, activity and behaviour outcomes were effective. Evidence of interventions that support children's and adolescent's participation as an outcome is lacking.

Improving health and well-being for infants with prenatal substance exposure

Substance use disorders (SUD) among caregiving adults has inexorable linkage to the health and well-being of millions of children in the U.S. This piece provides an overview of such linkages, examples of relevant policies and regulations, and the role of pediatric healthcare within the health trajectories of children and families at this intersection. A commonality throughout this work is need for non-stigmatizing engagement and support to facilitate connections to care and reduce barriers.

Improving the quality of antenatal screening and early intervention for alcohol and other drug use: protocol for a multi-stage approach to systems reform

BACKGROUND

Alcohol, tobacco and illicit drug use during pregnancy can cause significant harm to women and their developing fetuses. Despite recommendations for abstinence during pregnancy, some women continue to use, making screening for substance use during antenatal clinic attendances an important strategy for reducing risk. This study aims to improve the rates of screening and intervention for substance use among pregnant women, including appropriate referral for those who may be substance-dependent. The protocol outlined here focuses on a multi-stage implementation study.

METHODS

This study will occur in four phases. Phase 1 will identify a baseline rate of screening and subsequent care at the antenatal clinics of two, South Australian hospital-based maternity services, through a retrospective case note audit. Rates of self-reported substance use identified in the case notes will also be compared against representative data from Adelaide Primary Health Network to establish rates of over or underreporting. Phase 2 will involve an online Training Needs Analysis of midwifery staff working at those services, to assess their knowledge, attitudes, beliefs, and commitment to the care of women who use substances during pregnancy. Phase 3 will involve a training package for all midwifery staff at those services, focused on routine screening for substance use, and how to provide appropriate care. Outcome measures from phase 2 will be reassessed during phase 3 and any changes since training will be evaluated. Phase 4 will then repeat phase 1 to compare the changes in rates of both screening and any associated intervention before and after training.

DISCUSSION

From a public health perspective, this project has the potential to make a significant impact on reducing risk of harm from substance use disorders among pregnant women, and contribute to better health outcomes for their children.

Exposure to sexual content and problematic sexual behaviors in children and adolescents: A systematic review and meta-analysis

BACKGROUND

Exposure to sexual content, such as online pornography or live sexual content, has been posited in the literature as a risk factor for problematic sexual behaviors (PSBs) in children and adolescents, and has been identified as an important avenue for research and intervention, particularly given the ubiquitous access to technology among children.

OBJECTIVE

To examine the association between live/violent and non-violent sexual content exposure and PSB among children and adolescents. Objectives also include informing future research on sexual content exposure as a risk factor for PSB, and providing clinical recommendations related to prevention and intervention.

PARTICIPANTS AND SETTING

Results are based on 16,200 participants (28.65 % female; Mage = 14.26; range = 4.74-17.92) and 27 studies conducted in North America, Europe, Asia, and Africa.

METHODS

A systematic review was conducted of available literature published up to September 2021. Abstract and full-text review were conducted to assess whether studies met inclusion criteria. Random-effects meta-analyses were conducted on included studies.

RESULTS

Significant associations were found between exposure to non-violent sexual content and likelihood of engaging in PSB (OR = 1.82; p < .001; 95 % CI: 1.50-2.21), and between exposure to violent/live sexual content and PSB (OR = 2.52; p < .001; 95 % CI: 1.75-3.61). Sex emerged as a moderator of the association between exposure to non-violent sexual content and PSB, such that the association was stronger in studies with a greater proportion of females.

CONCLUSIONS

Results support the need for future research on risk factors and mechanisms implicated in PSB. Prevention and intervention programs for children with PSB and their families could benefit from incorporating education on sexual content exposure.

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.

Impact of the COVID-19 pandemic on adults with Fetal Alcohol Spectrum Disorder: linking immune function to mental health status

Prenatal alcohol exposure (PAE) is known to cause a variety of cognitive, behavioral, and neurological changes. Importantly, mental health problems are also overrepresented in individuals with Fetal Alcohol Spectrum Disorder (FASD), the group of neurodevelopmental conditions that can occur following PAE. Approximately 90% of individuals with FASD report experiencing mental health problems over their lifespan, compared to approximately 30% in the overall population. Individuals with FASD also display impairments in coping skills and increased vulnerability to stress. Here, we investigated whether the COVID-19 pandemic would have a differential impact on mental health and inflammation-to-mood associations in adults with FASD, compared to unexposed controls (no PAE). We capitalized on our pre-pandemic study examining health and immune function and invited past-participants to enroll in the current study. Participants completed mental health assessments and COVID-related questionnaires by phone. In addition, blood samples collected at baseline (pre-pandemic) were used to probe for inflammation-to-mood associations. Overall, our results indicate that lower SES was predictive of higher coronavirus anxiety scores, with no differences between adults with FASD and controls. In addition, while there were no differences in depression or anxiety measures at baseline (pre-pandemic) or during the pandemic, examination of inflammation-to-mood associations identified differential relationships in adults with FASD compared to unexposed controls. Specifically, there was a positive association between baseline neutrophil counts and both baseline and pandemic mental health scores in unexposed controls only. In addition, for unexposed controls there was also a negative association between baseline interferon-ɣ (IFN-ɣ) and pandemic mental health scores. By contrast, only adults with FASD showed positive associations between baseline interleukin-12p70 (IL-12p70), IL-8, soluble intercellular adhesion molecule-1 (sICAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) and pandemic mental health scores. Taken together, to our knowledge, this study is the first to examine the impact of the pandemic in adults with FASD. And while it may be too soon to predict the long-term effects of the pandemic on mental health, our data suggest that it will be important that future work also takes into account how immune function may be modulating mental health outcomes in this population.

Lived experiences of the diagnostic assessment process for fetal alcohol spectrum disorder: A systematic review of qualitative evidence

Early assessment and diagnosis of FASD are crucial in providing therapeutic interventions that aim to enhance meaningful participation and quality of life for individuals and their families, while reducing psychosocial difficulties that may arise during adolescence and adulthood. Individuals with lived experience of FASD have expertise based on their own lives and family needs. Their insights into the assessment and diagnostic process are valuable for improving service delivery and informing the provision of meaningful, person- and family-centered care. To date, reviews have focused broadly on the experiences of living with FASD. The aim of this systematic review is to synthesize qualitative evidence on the lived experiences of the diagnostic assessment process for FASD. Six electronic databases, including PubMed, the Cochrane Library, CINAH, EMBASE, PsycINFO, and Web of Science Core Collection were searched from inception until February 2021, and updated in December 2022. A manual search of reference lists of included studies identified additional studies for inclusion. The quality of included studies was assessed using the Critical Appraisal Skills Program Checklist for Qualitative Studies. Data from included studies were synthesized using a thematic analysis approach. GRADE-CERQual was used to assess confidence in the review findings. Ten studies met the selection criteria for inclusion in the review. Thematic analysis identified 10 first-level themes relating to four over-arching topics: (1) pre-assessment concerns and challenges, (2) the diagnostic assessment process, (3) receipt of the diagnosis, and (4) post-assessment adaptations and needs. GRADE-CERQual confidence ratings for each of the review themes were moderate to high. The findings from this review have implications for referral pathways, client-centered assessment processes, and post-diagnostic recommendations and support.

A tornado in the family: fetal alcohol spectrum disorder and aggression during childhood and adolescence: a scoping review

Background

Aggression exhibited by children and youth with Fetal Alcohol Spectrum Disorder (FASD) toward family members is a major cause of stress and anxiety for caregivers, but relatively little attention has been directed toward designing interventions specific to this phenomenon. In light of the serious negative impact of this issue for families, a scoping review was undertaken to summarize the evidence available on psychosocial interventions that may mitigate the frequency and severity of aggression exhibited by children and youth with FASD toward family members.

Methods

This review was designed using PRISMA-SCR and JBI scoping review guidelines. Three databases were searched in August 2021: EMBASE, PsychINFO, and Medline.

Results

A total of 1,061 studies were imported for screening with only five studies meeting full eligibility criteria. None of the interventions were aimed at specifically targeting aggression and instead reported on broader constructs of externalizing behaviors such as hyperactivity. The interventions were limited to school-aged children. Studies reported primarily on child outcomes while only one reported on family related outcomes.

Conclusion

Following from this review of the literature, we argue that aggression is a related but separate construct from other behavioral problems most frequently targeted by parenting interventions. Given the often dire consequence of aggression displayed by children and youth with FASD and the limited number of studies, there is an urgent need for research on how to support families to manage this specific type of behavior in this population.

An investigation of the utility of the Australian Guide to the diagnosis of fetal alcohol spectrum disorder in young children

BACKGROUND

Early diagnosis of children with fetal alcohol spectrum disorder (FASD) assists in implementing critical early support. The challenge lies in having a diagnostic process that enables valid and reliable assessment of domains of functioning in young children, with the added complexity that many children will also have co-occurring exposure to childhood adversity that is likely to impact these domains.

METHODS

The aim of this study was to test a diagnostic assessment of FASD in young children using the Australian Guide to the Diagnosis of FASD. Ninety-four children (aged 3 to 7 years) with confirmed or suspected prenatal alcohol exposure were referred to two specialist FASD clinics for assessment in Queensland, Australia.

RESULTS

There was a significant risk profile with 68.1% (n = 64) children having had contact with child protection services, and most children living in kinship (n = 22, 27.7%) or foster (n = 36, 40.4%) care. Forty-one percent of the children were Indigenous Australians. The majority (64.9%, n = 61) of children met criteria for FASD, 30.9% were classified as "At Risk" for FASD (n = 29), and 4.3% received no FASD diagnosis (n = 4). Only 4 (4%) children were rated as severe for the brain domain. Over 60% of children (n = 58) had two or more comorbid diagnoses. Sensitivity analyses indicated that the removal of comorbid diagnoses in the Attention, Affect Regulation, or Adaptive Functioning domains resulted in a change in 7 of 47 cases (15%) to an "At Risk" designation.

CONCLUSIONS

These results highlight the complexity of presentation and the extent of impairment in the sample. The use of comorbid diagnoses to substantiate a "severe" designation in specific neurodevelopmental domains raises the question of whether there were false-positive diagnoses. The complexity of determining causal relationships between exposure to PAE and early life adversity on developmental outcomes continues to be a challenge in this young population.

Adaptive behavior, sleep, and physical activity in adolescents with fetal alcohol spectrum disorder

BACKGROUND

Fetal alcohol spectrum disorder (FASD) is broadly associated with impairments to adaptive behavior and dysfunctional sleep. Associations between sleep, adaptive behavior, and physical activity are frequently drawn in discussions of typical development and other clinical conditions.

AIMS

In this study, we sought to characterize patterns of sleep, adaptive behavior, and physical activity in adolescents with FASD. We also investigated the associations between sleep, adaptive behavior, and physical activity within this population.

METHODS AND PROCEDURES

Twenty-seven adolescents aged 11- to 17-years with a diagnosis of FASD and their caregivers participated in this study. All participants completed parent and youth questionnaires on adaptive behavior, sleep, and physical activity.

OUTCOMES AND RESULTS

Adolescents with FASD displayed significant impairments to all domains of adaptive behavior and considerable sleep disturbance. Worse sleep was associated with older age and sleep-related breathing disturbances were associated with poorer social adaptive behavior. Participation in physical activity, particularly organized sport, was strongly associated with better adaptive behavior.

CONCLUSIONS AND IMPLICATIONS

Adolescents with FASD experience considerable challenges with regards to sleep and adaptive behavior. Physical activity, particularly organized sport, may provide opportunities for the improvement of adaptive behavior in this population.

Psychotropic Medication Utilization Among Children Diagnosed With Fetal Alcohol Spectrum Disorder

BACKGROUND AND OBJECTIVES

To date, there has been no large, population-based study estimating the prevalence of psychotropic medication use and cooccurring medical conditions among children with fetal alcohol syndrome disorder (FASD). In addition, it is not known how psychotropic medication use varies by mental health status of the children with FASD and their health insurance coverage. This study attempts to fill this gap by analyzing a large health insurance claims database covering Medicaid and private insurance.

METHODS

The study used the 2017 IBM Watson Health MarketScan Multistate Medicaid and Commercial Claims databases. The sample for the analysis includes children between the ages of 0 and 17 with either an FASD diagnosis or a mental health diagnosis (N = 848 721 Medicaid; N = 511 061 private insurance).

RESULTS

More than half of the children with an FASD diagnosis were prescribed psychotropic medications (63% Medicaid; 57% private). Utilization rates of psychotropic medication among children with cooccurring FASD and a mental health condition (79% Medicaid; 71% private) were higher compared to children with a mental health diagnosis but no FASD (57% Medicaid; 57% private). Stimulants were the most commonly prescribed. Encephalopathy, attention deficit hyperactivity disorder, and epilepsy were the 3 most common cooccurring diagnosis among children with FASD using psychotropic medication under Medicaid compared to encephalopathy, attention deficit hyperactivity disorder, and anxiety with private insurance.

CONCLUSIONS

These results exemplify the complexity of the neurobehavioral profile of children with FASD and the challenge of treatment. Future studies may determine how supportive services for these children will affect psychotropic medication use.

Online randomised factorial trial of electronic Screening and Brief Intervention for alcohol use in pregnancy: a study protocol

INTRODUCTION

Approximately 1 in 7 pregnant women in the USA report past-month alcohol use. Strong evidence connects prenatal alcohol exposure with a range of adverse perinatal outcomes, including the spectrum of conditions known as fetal alcohol spectrum disorders. Screening and Brief Intervention (SBI) has been recommended for pregnant women but has proven difficult to implement. This study will test the efficacy of single-session technology-delivered SBI (electronic SBI) for alcohol use in pregnancy, while simultaneously evaluating the possible additional benefit of tailored text messages and/or booster sessions in a 3×2 factorial trial.

METHOD AND ANALYSIS

This full factorial trial will use online advertising and clinic-based flyers to recruit pregnant women meeting criteria for unhealthy alcohol use, and randomly assign them to one of six conditions crossing three levels of brief intervention (none, single 120-minute session and single session plus two 5-minute boosters) with two levels of tailored text messaging (none vs twice weekly messages). The primary analysis will test for dose-response effects of the brief intervention on alcohol abstinence, defined as no self-report of alcohol use in the 90 days prior to 34 weeks' gestation, and negative results for ethyl glucuronide analysis of fingernail samples. Secondary analyses will examine main and interaction effects of tailored text messaging as well as intervention effects on birth outcomes.

ETHICS AND DISSEMINATION

Ethical approval was provided by the Michigan State University Biomedical and Health Institutional Review Board (STUDY00005298). Results will be presented at conferences and community forums, in addition to being published in a peer-reviewed journal. Intervention content demonstrating sufficient efficacy and safety will be made publicly available.

The contribution of the Neurobehavioral Screening Tool to identifying fetal alcohol spectrum disorders in children at high risk of prenatal alcohol exposure and neurobehavioral deficits

BACKGROUND

Fetal alcohol spectrum disorders (FASD) describe various conditions resulting from prenatal alcohol exposure. The diagnosis of FASD can be challenging and complex. The Neurobehavioral Screening Tool (NST), derived from Achenbach's Child Behavior Checklist, has been suggested as a tool for identifying FASD.

AIMS

To assess the external validity of the NST and to identify additional characteristics of FASD in a cohort of Israeli children and young adults referred to a neurology and child developmental clinic at a tertiary pediatric medical center in Israel.

STUDY DESIGN

An observational study based on medical records.

SUBJECTS

151 children and young adults, of whom 40 were diagnosed with FASD according to updated clinical guidelines.

OUTCOME MEASURES

NST results, as well as demographic and neurobehavioral variables, were compared between those who were and were not diagnosed with FASD.

RESULTS

The NST demonstrated 72 % to 73 % sensitivity, and 34 % to 36 % specificity, in identifying FASD. Items 4 and 5 ('Lies or cheats', 'Lacks guilt after misbehaving') were the most predictive items in the NST. Other variables that were characteristic of the FASD group included: emotional regulation difficulties (p value <0.01), being born and adopted in Israel (vs. other countries) (p value <0.01) and younger age at the first visit to the clinic (p value <0.01).

CONCLUSIONS

Our findings regarding the screening capabilities of the NST were less promising than those of most previous studies. Further research is needed to establish a valid neurobehavioral tool with the possible focus on antisocial behaviors and emotional regulation problems.

Potential Role of MANF, an ER Stress Responsive Neurotrophic Factor, in Protecting Against Alcohol Neurotoxicity

Alcohol exposure during pregnancy is harmful to the fetus and causes a wide range of long-lasting physiological and neurocognitive impairments, collectively referred to as fetal alcohol spectrum disorders (FASD). The neurobehavioral deficits observed in FASD result from structural and functional damages in the brain, with neurodegeneration being the most destructive consequence. Currently, there are no therapies for FASD. It is exigent to delineate the underlying mechanisms of alcohol neurotoxicity and develop an effective strategy of treatment. ER stress, caused by the accumulation of unfolded/misfolded proteins in the ER, is the hallmark of many neurodegenerative diseases, including alcohol-induced neurodegeneration. Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a newly discovered endoplasmic reticulum (ER) stress responsive neurotrophic factor that regulates diverse neuronal functions. This review summarizes the recent findings revealing the effects of MANF on the CNS and its protective role against neurodegeneration. Particularly, we focus the role of MANF on alcohol-induced ER stress and neurodegeneration and discuss the therapeutic potential of MANF in treating alcohol neurotoxicity such as FASD.

Evidence for long-lasting alterations in the fecal microbiota following prenatal alcohol exposure

BACKGROUND

There is growing evidence that the gut microbiota can be shaped by early-life experiences/exposures, with long-term consequences for brain, behavior, and health. Changes in the gut microbiota have also been identified in neurodevelopmental disorders including Autism Spectrum Disorder and schizophrenia. In contrast, no studies to date have investigated whether the gut microbiota is altered in individuals with Fetal Alcohol Spectrum Disorder (FASD), the neurodevelopmental disorder that results from prenatal alcohol exposure (PAE). The current study was designed to assess the impact of PAE on the fecal microbiota.

METHODS

We used a rodent model in which pregnant Sprague-Dawley rats were provided with an EtOH-containing diet or a control diet throughout gestation. Fecal samples were collected from adult male and female animals and 16s rRNA sequencing was performed.

RESULTS

Overall, PAE rats showed greater richness of bacterial species, with community structure investigations demonstrating distinct clustering by prenatal treatment. In addition, prenatal treatment and sex-specific alterations were observed for many specific microbes. For example, in males, Bacteroides and Bifidobacterium, and in females, Faecalitalea and Proteus, differed in abundance between PAE and control rats.

CONCLUSIONS

Taken together, these results show for the first time that PAE has a long-lasting and sex-specific impact on the fecal microbiota. Further research is needed that considers fetal microbiota in the development of new interventions in FASD.

Fetal alcohol spectrum disorders (FASD) and youth firesetting: A call on criminal justice, emergency responder, and fire prevention specialists to become informed

Central nervous system damage resulting from prenatal exposure to alcohol, often referred to as fetal alcohol spectrum disorders (FASD), commonly manifests as lacking cognitive functioning, problem solving, impulsivity, memory, executive functioning, and social skill deficits. For individuals with FASD, these brain-based deficits translate into impulsive behaviors and poorly thought-out decision-making, coupled with an inability to anticipate and recognize the sometimes very severe consequences of their behaviors. Not unexpectedly, individuals with FASD frequently find themselves disproportionately involved in the criminal justice system and mental health services. For some individuals with FASD, these behaviors can also include firesetting. First responders, like other health and legal professionals, are often unable to recognize the behavioral indicators of FASD, primarily due to a lack of training. As a result, firesetting behaviors are often attributed to deliberate, willful acts of delinquency, a desire to damage property, thrill seeking, or as attempts for personal gain, rather than being viewed as maladaptive attempts to solve problems by individuals who lack the tools to do this in more appropriate ways. These same skill deficits also present when individuals with FASD are interviewed about their involvement in such behaviors, sometimes resulting in confabulation, suggestibility, and false confessions. Further education and training in FASD are vital for first responders if they are to better support individuals with FASD and minimize their chances of becoming involved in firesetting behaviors. Furthermore, this training and education will help ensure that first responders can intervene in more appropriately when crisis situations do occur. This article will outline key behavioral symptoms of FASD as well as provide first responders with suggestions as to how to best support individuals when FASD is suspected. The brief quote that follows highlights some of the key challenges facing individuals with FASD and how poor decision-making and impulsiveness can result in severe consequences for the individual and those around them.

Longitudinal prediction of periconception alcohol use: a 20-year prospective cohort study across adolescence, young adulthood and pregnancy

BACKGROUND AND AIMS

Alcohol consumption is common in adolescence and young adulthood and may continue into pregnancy, posing serious risk to early fetal development. We examine the frequency of periconception alcohol use (prior to pregnancy awareness) and the extent to which adolescent and young adult alcohol use prospectively predict periconception use.

DESIGN

A longitudinal, population-based study.

SETTING

Victoria, Australia.

PARTICIPANTS

A total of 289 women in trimester three of pregnancy (age 29-35 years; 388 pregnancies).

MEASURES

The main exposures were binge [≥ 4.0 standard drinks (SDs)/day] and frequent (≥ 3 days/week) drinking in adolescence (mean age = 14.9-17.4 years) and young adulthood (mean age 20.7-29.1 years). Outcomes were frequency (≥ 3 days/week, ≥ monthly, never) and quantity (≥ 4.0 SDs, ≥ 0.5 and < 4.0 SDs, none) of periconception drinking.

FINDINGS

Alcohol use was common in young adulthood prior to pregnancy (72%) and in the early weeks of pregnancy (76%). The proportions drinking on most days and binge drinking were similar at both points. Reflecting a high degree of continuity in alcohol use behaviours, most women who drank periconceptionally had an earlier history of frequent (77%) and/or binge (85%) drinking throughout the adolescent or young adult years. Young adult binge drinking prospectively predicted periconception drinking quantity [odds ratio (OR) = 3.7, 95% confidence interval (CI) = 1.9-7.4], compared with women with no prior history. Similarly, frequent young adult drinking prospectively predicted frequent periconception drinking (OR = 30.7, 95% CI = 12.3-76.7).

CONCLUSIONS

Women who engage in risky (i.e. frequent and binge) drinking in their adolescent and young adult years are more likely to report risky drinking in early pregnancy prior to pregnancy recognition than women with no prior history of risky drinking.

Effects of prenatal alcohol exposure on cognitive and behavioral development: Findings from a hierarchical meta-analysis of data from six prospective longitudinal U.S. cohorts

BACKGROUND

Cognitive and behavioral sequelae of prenatal alcohol exposure (PAE) continue to be prevalent in the United States and worldwide. Because these sequelae are also common in other neurodevelopmental disorders, researchers have attempted to identify a distinct neurobehavioral profile to facilitate the differential diagnosis of fetal alcohol spectrum disorders (FASD). We used an innovative, individual participant meta-analytic technique to combine data from six large U.S. longitudinal cohorts to provide a more comprehensive and reliable characterization of the neurobehavioral deficits seen in FASD than can be obtained from smaller samples.

METHODS

Meta-analyses were performed on data from 2236 participants to examine effects of PAE (measured as oz absolute alcohol/day (AA/day)) on IQ, four domains of cognition function (learning and memory, executive function, reading achievement, and math achievement), sustained attention, and behavior problems, after adjusting for potential confounders using propensity scores.

RESULTS

The effect sizes for IQ and the four domains of cognitive function were strikingly similar to one another and did not differ at school age, adolescence, or young adulthood. Effect sizes were smaller in the more middle-class Seattle cohort and larger in the three cohorts that obtained more detailed and comprehensive assessments of AA/day. PAE effect sizes were somewhat weaker for parent- and teacher-reported behavior problems and not significant for sustained attention. In a meta-analysis of five aspects of executive function, the strongest effect was on set-shifting.

CONCLUSIONS

The similarity in the effect sizes for the four domains of cognitive function suggests that PAE affects an underlying component or components of cognition involving learning and memory and executive function that are reflected in IQ and academic achievement scores. The weaker effects in the more middle-class cohort may reflect a more cognitively stimulating environment, a different maternal drinking pattern (lower alcohol dose/occasion), and/or better maternal prenatal nutrition. These findings identify two domains of cognition-learning/memory and set-shifting-that are particularly affected by PAE, and one, sustained attention, which is apparently spared.

Embryonic Exposure to Ethanol Increases Anxiety-Like Behavior in Fry Zebrafish

AIMS

Fetal alcohol spectrum disorder (FASD) is an umbrella term to describe the effects of ethanol (Eth) exposure during embryonic development, including several conditions from malformation to cognitive deficits. Zebrafish (Danio rerio) are a translational model popularly applied in brain disorders and drug screening studies due to its genetic and physiology homology to humans added to its transparent eggs and fast development. In this study, we investigated how early ethanol exposure affects zebrafish behavior during the initial growth phase.

METHODS

Fish eggs were exposed to 0.0 (control), 0.25 and 0.5% ethanol at 24 h post-fertilization. Later, fry zebrafish (10 days old) were tested in a novel tank task and an inhibitory avoidance protocol to inquire about morphology and behavioral alterations.

RESULTS

Analysis of variance showed that ethanol doses of 0.25 and 0.5% do not cause morphological malformations and did not impair associative learning but increased anxiety-like behavior responses and lower exploratory behavior when compared to the control.

CONCLUSION

Our results demonstrate that one can detect behavioral abnormalities in the zebrafish induced by embryonic ethanol as early as 10 days post-fertilization and that alcohol increases anxious behavior during young development in zebrafish.

Evidence for the Effectiveness and Acceptability of e-SBI or e-SBIRT in the Management of Alcohol and Illicit Substance Use in Pregnant and Post-partum Women

Alcohol and illicit psychoactive drug use during pregnancy have increased worldwide, putting women and their children's health and development at risk. Multiple drug use, comorbid psychiatric disorders, sexual and physical abuse are common in women who use alcohol and drugs during pregnancy. The effects on the mother include poor reproductive and life-long health, legal, family, and social problems. Additionally, the exposed child is at increased risk of long-term physical health, mental health, and developmental problems. The stigma associated with substance use during pregnancy and some clinicians' reticence to inquire about substance use means many women are not receiving adequate prenatal, substance abuse, and mental health care. Evidence for mHealth apps to provide health care for pregnant and post-partum women reveal the usability and effectiveness of these apps to reduce gestational weight gain, improve nutrition, promote smoking cessation and manage gestational diabetes mellitus, and treat depression and anxiety. Emerging evidence suggests mHealth technology using a public health approach of electronic screening, brief intervention, or referral to treatment (e-SBIRT) for substance use or abuse can overcome the typical barriers preventing women from receiving treatment for alcohol and drug use during pregnancy. This brief intervention delivered through a mobile device may be equally effective as SBIRT delivered by a health care professional in preventing maternal drug use, minimizing the effects to the exposed child, and providing a pathway to therapeutic options for a substance use disorder. However, larger studies in more diverse settings with women who have co-morbid mental illness and a constellation of social risk factors that are frequently associated with substance use disorders are needed.

Social behaviors and gray matter volumes of brain areas supporting social cognition in children and adolescents with prenatal alcohol exposure

The goal of this study was to examine: 1) differences in parent-reported prosocial and antisocial behaviors between children and adolescents with and without prenatal alcohol exposure (PAE); 2) differences in gray matter volumes of brain areas supporting social cognition between children and adolescents with and without PAE; 3) correlations between gray matter volumes of brain areas supporting social cognition and parent-reported prosocial and antisocial behaviors. Parents of children and adolescents ages 8-16 years completed measures on their prosocial and antisocial behaviors (i.e., Behavior Assessment Scale for Children, Vineland Adaptive Behaviors Scales, and Child Behavior Checklist) (n = 84; 41 with PAE, 43 without PAE). Seventy-nine participants (40 with PAE, 39 without PAE) also completed a structural Magnetic Resonance Imaging (MRI) scan with quality data. Gray matter volumes of seven brain areas supporting social cognitive processes were computed using automated procedures (FreeSurfer 6.0): bilateral fusiform gyrus, superior temporal gyrus, medial orbitofrontal cortex, lateral orbitofrontal cortex, posterior cingulate cortex, precuneus, and temporal pole. Children and adolescents with PAE showed decreased prosocial behaviors and increased antisocial behaviors as well as smaller volumes of the precuneus and lateral orbitofrontal cortex, even when controlling for total intracranial volume. Social brain volumes were not significantly correlated with prosocial or antisocial behaviors. These findings suggest that children and adolescents with PAE show worse social functioning and smaller volumes of brain areas supporting self-awareness, perspective-taking and emotion-regulation than their same-age peers without PAE.

Health Disparities among Australia's Remote-Dwelling Aboriginal People: A Report from 2020

BACKGROUND

Australia has 2 distinct indigenous groups, Torres Strait Islanders and Aborigines. The Aborigines, described in this report, first colonized the continent 65 millennia ago. Those still living in the Northern Territory (NT) retain much ancestrally derived genetic complement but also are the most health-challenged by environment and lifestyle in 21st century. Reports providing overviews of these disparities are, as yet, rare.

CONTENT

This review defines the studied population and then describes and attempts to explain contemporary clinical findings among Australia's remote-dwelling Aborigines, principally in the NT. The report is structured by life stage and then by organ system. Finally, a brief synthesis is advanced concerning the disparities that Australia's Aboriginals face.

SUMMARY

In 2015-2017, NT aboriginal life expectancy for people then born was 66.6 years for men and 69.9 years for women compared with 78.1 and 82.7 years, respectively, among nonindigenous Territorians. Principal causes of the reduced longevity, with nonindigenous comparisons, include adolescent pregnancy, with maternal use of alcohol and tobacco (each 7-fold greater); fetal alcohol spectrum disorder and attention deficit hyperactivity disorder; skin infections, both scabies and impetigo (50-fold greater); rheumatic heart disease (260-fold greater); premature acute myocardial infarction (9-fold greater); bronchiectasis (40-fold greater); lung cancer (2-fold greater); diabetes mellitus (10-fold greater); renal failure (30-fold greater); and suicide (2-fold greater). Some disease has genetic roots, secondary to prolonged genetic drift. Much arises from avoidable stressors and from contemporary environmental disparities in housing. The Europid diet is also not helpful.

Association of fatty acid ethyl esters in meconium with behavior during childhood

OBJECTIVE

To examine associations between amounts of fatty acid ethyl esters (FAEEs) in meconium and behavior in school aged children exposed to alcohol and drugs in utero.

METHODS

A secondary analysis of a prospective cohort of cocaine, polydrug exposed children, primarily African-American, low socioeconomic status, recruited at birth into a longitudinal study. FAEEs were quantified with gas chromatography via a flame ionization detector. Meconium was analyzed for FAEEs for 216 newborns of whom 194 were assessed with the Child Behavior Checklist (CBCL) at ages 4, 6, 9, 10, 11, and 12. Generalized estimating equation analyses were used to assess the relationship of quantity of FAEEs to outcomes, controlling for maternal psychological distress.

RESULTS

Higher concentrations of FAEEs (ethyl myristate, ethyl palmitate, ethyl oleate, ethyl linoleate, and ethyl linolenate) were associated with caregiver reported aggressive and/or delinquent behavior at ages 10 and 12. After control for caregiver psychological distress, and age, significant (p < 0.05) FAEE by age interactions were found for ethyl myristate for aggression and for ethyl oleate, ethyl linoleate and ethyl linolenate for delinquency. Thus, higher concentrations of FAEE were related to more caregiver reported aggressive and delinquent behaviors of clinical significance at ages 10 and 12.

CONCLUSION

Higher concentrations of FAEEs in meconium are potential markers for children at risk for aggressive and delinquent behaviors related to the effects of prenatal alcohol exposure.

The oral health status and treatment needs of children with fetal alcohol spectrum disorder

OBJECTIVE

To investigate the oral health status and treatment needs of children with fetal alcohol spectrum disorder (FASD).

METHODS

In this retrospective study, the records of children between the ages of 6 and 14 who attended the College of Dentistry, University of Saskatchewan between 2016 and 2019 were reviewed. Demographic and clinical data was collected and compared for children who were identified as having FASD and a healthy control group.

RESULTS

From our total sample of 252 dental records, 68 children were identified with FASD. When compared to controls, children with FASD were significantly older at their first dental visit, and more dependent on public dental insurance. Children with FASD also had a significantly higher caries experience (97% vs 64.7%) and severity (DMFT/dmft score = 7.18 ± 1.79 vs 2.93 ± 0.98). Additionally, the results of our logistic regression model indicate that children with FASD were 4.71 times more likely (OR 4.71, 95% CI 1.58 -14.03) to be referred for treatment under general anesthesia (GA) when all other factors were controlled.

CONCLUSIONS

Children with FASD may be at a higher risk for poor oral health outcomes and have more extensive treatment needs. Our results indicate that they may also be at a higher risk for treatment under GA.

CLINICAL RELEVANCE

Oral healthcare providers need to be award of the unique needs of children with FASD to better prevent and manage their oral disease.

Demographic and Psychosocial Factors Associated With Child Sexual Exploitation: A Systematic Review and Meta-analysis

IMPORTANCE

Although research has examined factors associated with child sexual exploitation (CSE), consensus is lacking in regard to which factors should be prioritized, thereby hindering policy reform, prevention efforts, and development of early detection and intervention.

OBJECTIVE

To provide a meta-analytic synthesis of studies examining factors associated with CSE and to quantify their relative importance.

DATA SOURCES

Electronic databases searched to June 2019 included Medline, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature, EMBASE, and Informit, yielding 396 nonduplicative records. Literature search was performed in July 2019.

STUDY SELECTION

Inclusion criteria were quantitative investigations of sexual exploitation and mean sample age of 18 years or younger.

DATA EXTRACTION AND SYNTHESIS

Literature review and data extraction followed Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Thirty-seven studies met final inclusion criteria. Two independent reviewers extracted all relevant data. Random-effects meta-analyses were used to derive odds ratios (ORs) for each factor. Data were analyzed from September 1 to October 28, 2019, and prediction intervals calculated in June 2020.

MAIN OUTCOMES AND MEASURES

Child sexual exploitation, defined as coerced sexual acts between a child or a young person (aged ≤18 years) and an individual or a group in exchange for money, gifts, substances, or other commodities and associated factors.

RESULTS

Thirty-seven unique studies were included with a total of 67 453 unique participants (mean [SD] age of 16.2 [2.5] years; 49.9% female). Fifty-two factors associated with CSE were included in the meta-analysis. The strongest factors significantly associated with exposure to sexual exploitation were engagement in sexual risk behaviors (OR, 6.31 [95% CI, 3.12-12.76]; P < .001), having more than 5 sexual partners (OR, 5.96 [95% CI, 1.63-21.87]; P = .007), a diagnosis of posttraumatic stress disorder (OR, 5.29 [95% CI, 3.40-8.22]; P < .001), historical exposure to child pornography (OR, 5.50 [95% CI, 0.99-30.53]; P = .049), and a history of childhood sexual abuse (OR, 3.80 [95% CI, 3.19-4.52]; P < .001). A number of other potentially modifiable factors had moderate to strong associations.

CONCLUSIONS AND RELEVANCE

In this systematic review and meta-analysis, children and adolescents affected by sexual exploitation showed high levels of sexual risk taking, multiple sexual partners, posttraumatic stress disorder, exposure to child pornography, and childhood trauma. Accurate detection of CSE may prevent this type of sexual violence occurring to adolescents and/or provide opportunities for intervention and recovery. Therefore, prevention and intervention efforts will likely benefit from integrating these factors into screening, assessment, and treatment.

Searching for the Fetal Alcohol Behavioral Phenotype

This narrative review presents the emerging published evidence on the existence of a phenotypic behavior in children with fetal alcohol spectrum behavior. Such a phenotype, exhibiting high sensitivity, specificity, and predictive values, may assist clinicians and families in identifying children who often miss some of the information needed for full diagnosis, but who may benefit from these screening tools in mobilizing help to these youngsters and their families.

Incontinence in persons with fetal alcohol spectrum disorders: a polish cohort

INTRODUCTION

Fetal alcohol spectrum disorders (FASD) is an important preventable public health concern, associated to a number of common pediatric problems such as incontinence. Little is known about the prevalence and presentation of incontinence in FASD, which hinders effective management.

OBJECTIVE

The aim of the present study was to investigate incontinence among people with FASD.

STUDY DESIGN

Parental questionnaires were sent to all eligible FASD participants. To enable comparing the observed prevalence with typically developing, non-prenatally alcohol-exposed individuals, two clinical control groups of patients undergoing immunotherapy for pollen allergy (GKA) and patients diagnosed with celiac disease (GKG) were selected.

RESULTS

A total of 119 participants were included in the study (FAS: n = 24, partial fetal alcohol syndrome [pFAS]: n = 19, alcohol-related neurodevelopmental disorder [ARND]: n = 28, GKA: n = 34, and GKG: n = 14). Overall incontinence for FASD was estimated to be 24% (confidence interval [CI] ranges from 15 to 36); nocturnal enuresis (NE) was present in 10% (CI ranges from 4 to 19), daytime urinary incontinence (DUI) in 11% (CI ranges from 5 to 21), and fecal incontinence (FI) in 13% (CI ranges from 6 to 23). Symptoms of urgency were present for 52%, voiding postponement for 10%, and straining for 2%. These data are both consistent with higher prevalence in individuals with FASD and with similar prevalence (the CIs overlap).

CONCLUSION

Children and adolescents with FAS, pFAS, ARND, GKA, and GKG are affected by incontinence. Highest rates were observed in pFAS and ARND. Persons with FAS were mostly affected by DUI, those with pFAS by NE, and those with ARND by FI.

Chronic Ethanol Exposure Alters DNA Methylation in Neural Stem Cells: Role of Mouse Strain and Sex

Prenatal alcohol exposure (PAE) is considered as a risk factor for the development of fetal alcohol spectrum disorders (FASD). Evidence indicates that PAE affects epigenetic mechanisms (such as DNA methylation) and alters the normal differentiation and development of neural stem cells (NSC) in the fetal brain. However, PAE effects depend on several factors such as sex and strain of the studied subjects. Here, we investigated whether murine sex and strain contribute to the effects of chronic ethanol exposure on DNA methylation machinery of differentiating NSC. Further, the effects of PAE on glial lineage (including both astrocytes and oligodendrocytes) in a sex- and strain-dependent manner have not been studied yet. To examine the effects of chronic ethanol exposure on gliogenesis, we exposed differentiating NSC to glio-inductive culture conditions. Applying a standard in vitro model system, we treated male and female differentiating NSC (obtained from the forebrain of CD1 and C57BL/6 embryos at embryonic day 14.5) with chronic ethanol exposure (70 mM) for 8 days. We show that ethanol induces global DNA hypomethylation, while altering the expression of DNA methylation-related genes in a sex- and strain-specific manner. The observed change in cellular DNA methylation levels was associated with altered expression of glial markers CNPASE, GFAP, and OLIG2 in CD1 (but not C57BL/6) cells. We conclude that the impact of ethanol effect on DNA methylation is dependent on cellular sex and strain. Also, ethanol impact on neural stem cell fate commitment was only detected in cells isolated from CD1 mouse strain, but not in C57BL/6 cells. The results of the current study provide evidence that sex and strain of rodents (C57BL/6 and CD1) during gestation are important factors, which affect alcohol effects on NSC differentiation and DNA methylation. Results of this study may also help in interpreting data on the developmental toxicity of many compounds during the gestational period.

Immune network dysregulation associated with child neurodevelopmental delay: modulatory role of prenatal alcohol exposure

Background

Evidence suggests that cytokine imbalances may be at the root of deficits that occur in numerous neurodevelopmental disorders, including schizophrenia and autism spectrum disorder. Notably, while clinical studies have demonstrated maternal cytokine imbalances with alcohol consumption during pregnancy—and data from animal models have identified immune disturbances in alcohol-exposed offspring—to date, immune alterations in alcohol-exposed children have not been explored. Thus, here we hypothesized that perturbations in the immune environment as a result of prenatal alcohol exposure will program the developing immune system, and result in immune dysfunction into childhood. Due to the important role of cytokines in brain development/function, we further hypothesized that child immune profiles might be associated with their neurodevelopmental status.

Methods

As part of a longitudinal study in Ukraine, children of mothers reporting low/no alcohol consumption or moderate-to-heavy alcohol consumption during pregnancy were enrolled in the study and received neurodevelopmental assessments. Group stratification was based on maternal alcohol consumption and child neurodevelopmental status resulting in the following groups: A/TD, alcohol-consuming mother, typically developing child; A/ND, alcohol-consuming mother, neurodevelopmental delay in the child; C/TD, control mother (low/no alcohol consumption), typically development child; and C/ND, control mother, neurodevelopmental delay in the child. Forty cytokines/chemokines were measured in plasma and data were analyzed using regression and constrained principle component analysis.

Results

Analyses revealed differential cytokine network activity associated with both prenatal alcohol exposure and neurodevelopmental status. Specifically, alcohol-exposed children showed activation of a cytokine network including eotaxin-3, eotaxin, and bFGF, irrespective of neurodevelopmental status. However, another cytokine network was differentially activated based on neurodevelopmental outcome: A/TD showed activation of MIP-1β, MDC, and MCP-4, and inhibition of CRP and PlGF, with opposing pattern of activation/inhibition detected in the A/ND group. By contrast, in the absence of alcohol-exposure, activation of a network including IL-2, TNF-β, IL-10, and IL-15 was associated with neurodevelopmental delay.

Conclusions

Taken together, this comprehensive assessment of immune markers allowed for the identification of unique immune milieus that are associated with alcohol exposure as well as both alcohol-related and alcohol-independent neurodevelopmental delay. These findings are a critical step towards establishing unique immune biomarkers for alcohol-related and alcohol-independent neurodevelopmental delay.

Neurodevelopmental Outcomes Associated with Prefrontal Cortical Deoxygenation in Children with Fetal Alcohol Spectrum Disorders

Relationships between neurodevelopmental functioning and hemodynamic changes in the prefrontal cortex (PFC) were contrasted between children with prenatal alcohol exposure (PAE) and children who differed relative to their history of PAE and the presence of other neurodevelopmental impairment. For all groups, deoxygenated hemoglobin (HBR) levels in the medial PFC area were negatively related to externalizing problems and levels in the medial and right lateral PFC were positively related to errors on a cognitive inhibition task. Hemodynamic changes in the medial and right lateral PFC of children with PAE demonstrated stronger relationships to aspects of executive functioning relative to contrast groups.

Prenatal alcohol use as a risk for attention-deficit/hyperactivity disorder

The objective of the study was to investigate the association between alcohol use during pregnancy and mental disorders in childhood, controlling for confounding risk factors by a longitudinal study of pregnant women and their offspring. The initial cohort comprised pregnant women attending an obstetric service. From the initial sample of 449 pregnant women, 81 mother-child pairs agreed to participate. After 12 years, mother-child pairs were assessed through self-administered questionnaires and semi-structured interviews. The Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL) was used to assess the presence of any mental disorders in the children. The mothers were assessed by the Self-Reporting Questionnaire (SRQ) and the Alcohol Use Disorders Identification Test (AUDIT). Furthermore, data on the mother's alcohol use collected during pregnancy were analysed. A logistic regression tested the influence of alcohol consumption in all trimesters and binge drinking on the occurrence of attention-deficit/hyperactivity disorder (ADHD), controlling for covariates. Binge drinking at any time during pregnancy or low-moderate alcohol consumption in all trimesters of pregnancy was associated with a fivefold increased odds of child ADHD. The combination of both patterns of alcohol use added an increase of 19% in the variance of ADHD's occurrence. The episodic use of at least four drinks or the regular use of low-moderate alcohol doses during pregnancy was associated with significantly increased odds of subsequent child ADHD. Reducing binge drinking and regular alcohol use of pregnant women may lead to a significant decrease in their children developing ADHD.

Association of Sexting With Sexual Behaviors and Mental Health Among Adolescents: A Systematic Review and Meta-analysis

IMPORTANCE

Sexting is the exchange of sexual messages, photographs, or videos via technological devices and is common and increasing among youth. Although various studies have examined the association between sexting, sexual behaviors, and mental health, results are mixed.

OBJECTIVE

To provide a meta-analytic synthesis of studies examining the associations between sexting, sexual behavior, and mental health using sex, age, publication date, and study methodological quality as moderators.

DATA SOURCES

Electronic searches were conducted in April 2018 in MEDLINE, PsycINFO, Embase, and Web of Science, yielding 1672 nonduplicate records.

STUDY SELECTION

Studies were included if participants were younger than 18 years and an association between sexting and sexual behaviors or mental health risk factors was examined.

DATA EXTRACTION AND SYNTHESIS

All relevant data were extracted by 2 independent reviewers. Random-effects meta-analyses were used to derive odds ratios (ORs).

MAIN OUTCOMES AND MEASURES

Sexual behavior (sexual activity, multiple sexual partners, lack of contraception use) and mental health risk factors (anxiety/depression, delinquent behavior, and alcohol, drug use, and smoking).

RESULTS

Participants totaled 41 723 from 23 included studies. The mean (range) age was 14.9 (11.9-16.8) years, and 21 717 (52.1%) were female. Significant associations were observed between sexting and sexual activity (16 studies; OR, 3.66; 95% CI, 2.71-4.92), multiple sexual partners (5 studies; OR, 5.37; 95% CI, 2.72-12.67), lack of contraception use (6 studies; OR, 2.16; 95% CI, 1.08-4.32), delinquent behavior (3 studies; OR, 2.50; 95% CI, 1.29-4.86), anxiety/depression (7 studies; OR, 1.79; 95% CI, 1.41-2.28), alcohol use (8 studies; OR, 3.78; 95% CI, 3.11-4.59), drug use (5 studies; OR, 3.48; 95% CI, 2.24-5.40), and smoking behavior (4 studies; OR, 2.66; 95% CI, 1.88-3.76). Moderator analyses revealed that associations between sexting, sexual behavior, and mental health factors were stronger in younger compared to older adolescents.

CONCLUSIONS AND RELEVANCE

Results of this meta-analysis suggest that sexting is associated with sexual behavior and mental health difficulties, especially in younger adolescents. Longitudinal research is needed to assess directionality of effects and to analyze the mechanisms by which sexting and its correlates are related. Educational campaigns to raise awareness of digital health, safety, and security are needed to help youth navigate their personal, social, and sexual development in a technological world.

Is the association between maternal alcohol consumption in pregnancy and pre-school child behavioural and emotional problems causal? Multiple approaches for controlling unmeasured confounding

BACKGROUND AND AIMS

Hazardous drinking (i.e. alcohol consumption that places drinkers at risk for adverse health outcomes) during pregnancy is associated with adverse child outcomes. To address whether the associations are causal, we aimed to estimate the effect of maternal hazardous drinking during the first trimester on offspring emotional and behavioural problems throughout the pre-school age. We adjusted for: (1) measured confounding (e.g. smoking), (2) familial risk factors by sibling control design and (3) non-shared environmental risk factors by using hazardous drinking the 3 months before pregnancy as an instrumental variable.

DESIGN

Prospective cohort study. Participants were recruited between 1999 and 2009 at ultrasound examination offered to all pregnant women in Norway. Data were collected during the 17th and the 30th weeks of gestation, and when the children were aged 1.5, 3 and 5 years.

SETTING

Norway, 1999-2015.

PARTICIPANTS

The sample consisted of 14 639 mothers with 25 744 offspring siblings from the Norwegian Mother and Child Cohort Study.

MEASUREMENTS

Respondents self-reported on: alcohol consumption, children's emotional problems (i.e. emotional reactive, anxiety/depression, somatic complaints) and children's behavioural problems (i.e. attention and aggressive behaviour) throughout pre-school age. We used longitudinal latent growth curve models to estimate the effect of maternal drinking during the first trimester on offspring emotional and behavioural problems.

FINDINGS

Most associations were strongly reduced after controlling for both familial and measured environmental risk factors. After adjustment, exposed children were more emotionally reactive [β = 2.33; 95% confidence interval (CI) = 0.13-4.53] and had more somatic complaints (β = 1.93; 95% CI = 0.09-3.77) at age 3, but not at age 5. Exposed children were less aggressive than unexposed siblings at age 5 (β = -2.27; 95% CI = -4.02 to -0.52).

CONCLUSIONS

Children exposed to their mothers' hazardous drinking during the first trimester appear to be more emotionally reactive and have more somatic complaints at age 3, but not at age 5, and are less aggressive at age 5 compared with unexposed siblings.

Behaviour and adaptive functioning in children and young people with fetal alcohol spectrum disorders: a UK study

Purpose

The purpose of this paper is to explore the profiles of behaviours and adaptive functioning in the UK children and young people with fetal alcohol spectrum disorders.

Design/methodology/approach

Data of 106 participants registered from 2005 to 2015 were extracted from a clinic database. In total, 99 individuals with confirmed prenatal alcohol exposure (PAE), aged from 5 to 25 years, were analysed using scaled scores of the Vineland Adaptive Behavior Scales-Second Edition (VABS-II), and the Developmental Behaviour Checklist-Primary Carer Version (DBC-P) and Teacher Version (DBC-T). Differences due to age, gender, IQ and family structure (adopted/living with birth parents) were also explored.

Findings

The mean composite adaptive behaviour score on the VABS-II was classified as “low” at 68.2 (SD=8.5), with the socialisation domain being the most impaired. Significantly lower VABS-II composite scores were found in individuals with lower IQ’s, older ages and in males. Disruptive behaviours were the most commonly observed on the DBCs, whereas primary carers scored significantly higher than teachers across all subscales. IQ, age and gender were not associated with the total percentile scores of both DBCs. Adoption made no differences compared to living with birth parents.

Research limitations/implications

Future studies would replicate these findings in a larger sample size including individuals without PAE and those living with birth parents.

Originality/value

This study is the first UK report that examines this issue.

The picture talk project: Aboriginal community input on consent for research

BACKGROUND

The consent and community engagement process for research with Indigenous communities is rarely evaluated. Research protocols are not always collaborative, inclusive or culturally respectful. If participants do not trust or understand the research, selection bias may occur in recruitment, affecting study results potentially denying participants the opportunity to provide more knowledge and greater understanding about their community. Poorly informed consent can also harm the individual participant and the community as a whole.

METHODS

Invited by local Aboriginal community leaders of the Fitzroy Valley, the Kimberley, Western Australia, The Picture Talk project explores the consent process for research. Focus groups of Aboriginal community members were conducted to establish preferences for methods of seeking individual consent. Transcripts were analysed through NVivo10 Qualitative software using grounded theory with inductive and deductive coding. Themes were synthesised with quotes highlighted.

RESULTS

Focus groups with Aboriginal community members (n = 6 focus groups of 3-7 participants) were facilitated by a Community Navigator as a cultural guide and interpreter and a researcher. Participants were recruited from all main language groups of the Fitzroy Valley - Gooniyandi, Walmajarri, Wangkatjungka, Bunuba and Nikinya. Participants were aged ≥18 years, with 5 female groups and one male group. Themes identified include: Reputation and trust is essential; The Community Navigator is key; Pictures give the words meaning - milli milli versus Pictures; Achieving consensus in circles; Signing for consent; and Research is needed in the Valley.

CONCLUSION

Aboriginal communities of the Fitzroy Valley recommend that researchers collaborate with local leaders, develop trust and foster a good reputation in the community prior to research. Local Aboriginal researchers should be employed to provide cultural guidance throughout the research process and interpret local languages especially for elders. Pictures are preferred to written text to explain research information and most prefer to sign for consent. The Fitzroy Valley welcomes research when collaborative and for the benefit of the community. Future research could include exploring how to support young people, promote health screening and improve understanding of medical knowledge.

Fetal alcohol spectrum disorder in Australia: What is the current state of affairs?

The term fetal alcohol spectrum disorder (FASD) is used to describe a wide range of difficulties that individuals who are exposed to alcohol prenatally can face. FASD is a significant public health concern that is currently under-recognised and consequently, under-diagnosed in Australia. A new Commonwealth FASD Strategy (2018-2028) is being developed and the Australian Government has announced significant funding for the expansion of FASD prevention, diagnostic and intervention services around Australia. Therefore, it is timely to consider what the current state of affairs regarding FASD in Australia is and describe areas for future research and service delivery.

Prenatal alcohol consumption and infant and child behavior: Evidence from the Growing Up in New Zealand Cohort

BACKGROUND

High levels of alcohol exposure during pregnancy can damage developing brains and influence child behavior and learning.

AIM

To examine the effects of lower levels of alcohol and very early exposure to alcohol on infant temperament and child behavior.

STUDY DESIGN, SUBJECTS, AND OUTCOME MEASURES

The Growing Up in New Zealand study involves a prospective birth cohort of 6822 pregnant women of whom 6156 provided information on their child's temperament using the Infant Behavior Questionnaire-Revised (IBQ-R VSF) at 9 months and their child's behavior using the Strengths and Difficulties Questionnaire at 2 years.

RESULTS

A series of adjusted linear regression models controlling for socio-demographic factors found alcohol consumption during pregnancy was most consistently related to Lower Positive Affect, Affiliation/Regulation, and Orienting Capacity temperament scores. Mothers who stopped drinking after becoming aware of their pregnancy, but had an unplanned pregnancy (hence may have a baby exposed to alcohol for longer), also reported infants with lower Orienting Capacity, Affiliation/Regulation, and Fear temperament scores compared to those that did not drink. Children whose mothers drank four or more drinks per week during pregnancy were more likely to report their child as having conduct problems, with higher total difficulties scores at age 2.

CONCLUSIONS

Alcohol consumption during pregnancy has a negative effect especially on infant temperament, even if small amounts of alcohol are consumed. Our findings have implications for men and women who drink, medical professionals, and for the availability of contraception to those who drink, but do not plan to get pregnant.

The Prevalence of Unwanted Online Sexual Exposure and Solicitation Among Youth: A Meta-Analysis

PURPOSE

The objective of this meta-analysis was to provide a synthesis of studies examining the prevalence of unwanted online exposure and solicitation of a sexual nature among youth, and to determine if prevalence varies by youth age, gender, year of study data collection, or study geographical location.

METHOD

Eligible studies from January 1990 to January 2016 were identified utilizing a comprehensive search strategy. Included studies examined the prevalence of unwanted online exposure and solicitation in youth who ranged from 12 to 16.5 years. Two independent coders extracted all relevant data. Random-effects meta-analyses were used to derive mean prevalence rates.

RESULTS

Thirty-one (37,649 participants) and nine (18,272 participants) samples were included in the syntheses on unwanted online sexual exposure and solicitation, respectively. For online exposure, the mean prevalence rate was 20.3% (95% confidence interval: 17.1-23.4). For online solicitation, the mean prevalence rate was 11.5% (95% confidence interval: 9.4-13.6). Moderator analyses indicated that prevalence rates for unwanted online exposure and solicitation have decreased over time. Prevalence varied as a function of gender (solicitations were higher for males), but not age or geographical location.

CONCLUSIONS

Approximately one in five youth experience unwanted online exposure to sexually explicit material and one in nine youth experience online sexual solicitation. Educational campaigns to raise awareness of Internet risks and safety strategies are warranted.

Testing the programming of temperament and psychopathology in two independent samples of children with prenatal substance exposure

Prenatal programming models have rarely been applied to research on children with prenatal substance exposure, despite evidence suggesting that prenatal drug exposure is a form of stress that impacts neurodevelopmental outcomes and risk for psychopathology. Utilizing data from two longitudinal multisite studies comprising children prenatally exposed to substances as well as a nonexposed comparison group (Maternal Lifestyle Study, n = 1,388; Infant Development, Environment, and Lifestyle study, n = 412), we tested whether early phenotypic indicators of hypothesized programming effects, indexed by growth parameters at birth and infant temperament, served as a link between prenatal substance exposure and internalizing and externalizing behavior at age 5. Latent profile analysis indicated that individual differences in reactivity and regulation for infants prenatally exposed to substances was best characterized by four temperament profiles. These profiles were virtually identical across two independent samples, and demonstrated unique associations with adjustment difficulties nearly 5 years later. Results of path analysis using structural equation modeling also showed that increased prenatal substance exposure was linked to poorer growth parameters at birth, profiles of temperamental reactivity in infancy, and internalizing and externalizing behavior at age 5. This pathway was partially replicated across samples. This study was among the first to link known individual-level correlates of prenatal substance exposure into a specific pathway to childhood problem behavior. Implications for the developmental origins of a child's susceptibility to psychopathology as a result of intrauterine substance exposure are discussed.

Risk for Childhood Internalizing and Externalizing Behavior Problems in the Context of Prenatal Alcohol Exposure: A Meta-Analysis and Comprehensive Examination of Moderators

Prenatal alcohol exposure (PAE) is associated with a constellation of physical, neurocognitive, and behavioral abnormalities in offspring. The presence of internalizing (e.g., anxiety, mood disorders) and externalizing (e.g., oppositional defiant and conduct disorders) behavior problems has devastating and often long-lasting impacts on children, adolescents, and their families. The present meta-analysis explored the strength of the association between PAE and behavior problems, as well as factors that increase or mitigate risk. The current meta-analysis included 65 studies comparing children and adolescents with PAE to non- or light-exposed controls and attention-deficit/hyperactivity disorder (ADHD) samples, on a variety of internalizing and externalizing behavior outcomes. Results indicated that individuals with PAE are at increased risk for internalizing (d = 0.71, medium effect) and externalizing (d = 0.90, large effect) problems compared to control samples. The occurrence of total behavior problems was similar to that seen in ADHD samples. The strength of the association between internalizing and externalizing behavior problems and PAE was significantly moderated by several distinct sample characteristics, such as sample age, socioeconomic status, severity of exposure, and type of behavior problem. These findings further our understanding of the behavior problems experienced by children and adolescents with PAE.

Applying a Developmental Framework to the Self-Regulatory Difficulties of Young Children with Prenatal Alcohol Exposure: A Review

Prenatal alcohol exposure (PAE) can be associated with significant difficulties in self-regulatory abilities. As such, interventions have been developed that focus on improving varying aspects of self-regulation for this population. The application of a multilevel theoretical framework that describes the development of self-regulation during early childhood could further advance the field. First, this framework could assist in elucidating mechanisms in the trajectories of early adjustment problems in this population and, second, informing the development of more precise assessment and interventions for those affected by PAE. The aims of the current review were to provide an overview of the self-regulatory framework proposed by Calkins and colleagues (e.g., Calkins, 2007; Calkins and Fox, 2002); examine the self-regulatory difficulties that are commonly experienced during infancy (i.e., 0 to 2 years) and early childhood (i.e., 3 to 8 years) in children with PAE in the context of the developmental framework; and describe how the framework can inform the development of future assessment and intervention provision for young children with PAE. The application of a developmental framework, such as proposed by Calkins and colleagues, allows for a systematic and theoretically driven approach to assessment and intervention programs for young children with PAE.
