Demographic and health characteristics associated with fish and n-3 fatty acid supplement intake during pregnancy: results from pregnancy cohorts in the ECHO programme.

OBJECTIVE: n-3 fatty acid consumption during pregnancy is recommended for optimal pregnancy outcomes and offspring health. We examined characteristics associated with self-reported fish or n-3 supplement intake. DESIGN: Pooled pregnancy cohort studies. SETTING: Cohorts participating in the Environmental influences on Child Health Outcomes (ECHO) consortium with births from 1999 to 2020. PARTICIPANTS: A total of 10 800 pregnant women in twenty-three cohorts with food frequency data on fish consumption; 12 646 from thirty-five cohorts with information on supplement use. RESULTS: Overall, 24·6 % reported consuming fish never or less than once per month, 40·1 % less than once a week, 22·1 % 1-2 times per week and 13·2 % more than twice per week. The relative risk (RR) of ever (v. never) consuming fish was higher in participants who were older (1·14, 95 % CI 1·10, 1·18 for 35-40 v. <29 years), were other than non-Hispanic White (1·13, 95 % CI 1·08, 1·18 for non-Hispanic Black; 1·05, 95 % CI 1·01, 1·10 for non-Hispanic Asian; 1·06, 95 % CI 1·02, 1·10 for Hispanic) or used tobacco (1·04, 95 % CI 1·01, 1·08). The RR was lower in those with overweight v. healthy weight (0·97, 95 % CI 0·95, 1·0). Only 16·2 % reported n-3 supplement use, which was more common among individuals with a higher age and education, a lower BMI, and fish consumption (RR 1·5, 95 % CI 1·23, 1·82 for twice-weekly v. never). CONCLUSIONS: One-quarter of participants in this large nationwide dataset rarely or never consumed fish during pregnancy, and n-3 supplement use was uncommon, even among those who did not consume fish.

ADHD and risk for subsequent adverse childhood experiences: understanding the cycle of adversity.

BACKGROUND: Children with adverse childhood experiences (ACEs) are more likely to develop Attention-Deficit/Hyperactivity Disorder (ADHD). The reverse relationship - ADHD predicting subsequent ACEs - is vastly understudied, although it may be of great relevance to underserved populations highly exposed to ACEs. METHODS: Participants were 5- to 15-year-olds (48% females) with (9.9%) and without ADHD (DSM-IV criteria except age of onset) in a longitudinal population-based study of Puerto Rican youth. In each wave (3 yearly assessments, W1-3), ten ACEs (covering parental loss and maladjustment and child maltreatment) were examined, plus exposure to violence. Logistic regression models examined ADHD (including subtypes) and subsequent risk for ACEs. Also considered were interactions by age, sex, number of W1 ACEs, and recruitment site. RESULTS: Children with W1 ADHD were more likely to experience subsequent adversity (OR: 1.63; 95% CI: 1.12-2.37) accounting for child age, sex, public assistance, maternal education, site, disruptive behavior disorders, and W1 ACEs. Inattentive (OR: 2.00; 95% CI: 1.09-3.66), but not hyperactive/impulsive or combined ADHD, predicted future ACEs. CONCLUSIONS: ADHD predicts subsequent risk for ACEs, and the inattentive presentation may confer the most risk. Inattentive presentations could pose a bigger risk given differences in symptom persistence, latency to access to treatment, and treatment duration. The present study suggests a pathway for the perpetuation of adversity, where bidirectional relationships between ADHD and ACEs may ensnare children in developmental pathways predictive of poor outcomes. Understanding the mechanism underlying this association can help the development of interventions that interrupt the cycle of adversity exposure and improve the lives of children with ADHD.

Prenatal Developmental Origins of Future Psychopathology: Mechanisms and Pathways.

The developmental origins of health and disease hypothesis applied to neurodevelopmental outcomes asserts that the fetal origins of future development are relevant to mental health. There is a third pathway for the familial inheritance of risk for psychiatric illness beyond shared genes and the quality of parental care: the impact of pregnant women's distress-defined broadly to include perceived stress, life events, depression, and anxiety-on fetal and infant brain-behavior development. We discuss epidemiological and observational clinical data demonstrating that maternal distress is associated with children's increased risk for psychopathology: For example, high maternal anxiety is associated with a twofold increase in the risk of probable mental disorder in children. We review several biological systems hypothesized to be mechanisms by which maternal distress affects fetal and child brain and behavior development, as well as the clinical implications of studies of the developmental origins of health and disease that focus on maternal distress. Development and parenting begin before birth.

Neural Processing of Threat Cues in Young Children With Attention-Deficit/Hyperactivity Symptoms.

A growing literature indicates that attention deficit/hyperactivity disorder (ADHD) involves difficulty processing threat-related emotion faces. This deficit is especially important to understand in young children, as threat emotion processing is related to the development of social skills and related behavioral regulation. Therefore, the current study aimed to better understand the neural basis of this processing in young children with ADHD symptoms. Forty-seven children between 4 and 7 years of age were included in the analysis, 28 typical developing and 19 with clinically significant levels of ADHD hyperactive/impulsive symptoms. Participants completed a passive affective face-viewing task. Event-related potentials were assessed for each emotion, and parental report of child behavior and emotion regulation abilities was assessed. Children with ADHD symptoms showed altered N170 modulation in response to specific emotion faces, such that the N170 was less negative in response to fearful compared to neutral faces, whereas typically developing children showed the opposite pattern. Groups did not differ in reactivity to anger or non-threat-related emotion faces. The N170 difference in fearful compared to neutral faces correlated with reported behavior, such that less fear reactivity predicted fewer prosocial behaviors. Abnormalities in the underlying neural systems for fear processing in young children with ADHD symptoms may play an important role in social and behavioral deficits within this population.

REM theta activity enhances inhibitory control in typically developing children but not children with ADHD symptoms.

Sleep disturbances impair cognitive functioning in typically developing populations. Children with attention-deficit/hyperactivity disorder (ADHD), a disorder characterized by impaired inhibitory control and attention, commonly experience sleep disturbances. Whether inhibitory impairments are related to sleep deficits in children with ADHD is unknown. Children with ADHD (n = 18; M age = 6.70 years) and typically developing controls (n = 15; M age = 6.73 years) completed a Go/No-Go task to measure inhibitory control and sustained attention before and after polysomnography-monitored overnight sleep. Inhibitory control and sustained attention were improved following overnight sleep in typically developing children. Moreover, morning inhibitory control was positively correlated with rapid eye movement (REM) theta activity in this group. Although REM theta activity was greater in children with ADHD compared to typically developing children, it was functionally insignificant. Neither inhibitory control nor sustained attention was improved following overnight sleep in children with ADHD symptoms, and neither of these behaviors was associated with REM theta activity in this group. Taken together, these results indicate that elevated REM theta activity may be functionally related to ADHD symptomology, possibly reflecting delayed cortical maturation.

Longitudinal changes in individual symptoms across the preschool years in children with ADHD.

The present study examined trajectories of individual Diagnostic and Statistical Manual of Mental Disorders (4th ed.) symptoms of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) across the preschool years in children with ADHD. It also evaluated whether preschool symptoms vary in their ability to discriminate children who later meet criteria for ADHD from typically developing children. ADHD and ODD symptoms were assessed annually in 75 ethnically diverse children (46 boys) who presented with behavior problems at age 3 and met criteria for ADHD 3 years later, and in 51 typically developing children (26 boys). Children with ADHD generally exhibited stable levels of hyperactivity/impulsivity but increases in several symptoms of inattention. Most ADHD symptoms showed at least fair utility in discriminating children with and without ADHD; however, 3 symptoms of inattention (carelessness, losing things, and forgetfulness) and 1 symptom of hyperactivity/impulsivity (blurting out answers) had relatively poor utility. These symptoms demonstrated only somewhat greater utility at age 4, but by the age of 5 were better able to classify children. Children with ADHD exhibited increases in several ODD symptoms, including symptoms related to negative affect. Although most symptoms of hyperactivity/impulsivity appear to extend well down to age 3, more developmentally appropriate symptoms of inattention may be required to develop more sensitive assessments for 3- and 4-year-old children.

Emotion Socialization Practices in Latina and European American Mothers of Preschoolers with Behavior Problems.

The present study examined mothers' emotion socialization of 3-year-old children with behavior problems, to determine whether emotion socialization practices, as well as the relation between these practices and child functioning, varied across ethnicities. Participants were 134 preschoolers with behavior problems. Mothers were European American (n = 96) and Latina American (n = 38; predominately Puerto Rican). Audiotaped mother-child interactions were coded for emotion socialization behaviors. Latina and European American mothers used similar emotion socialization practices on most dimensions. Latina mothers were more likely to minimize or not respond to their children's negative affect. However, this difference did not appear to have ramifications for children. This study provided evidence for both differences and similarities across ethnicities on emotion socialization practices.

The role of parent psychopathology in the development of preschool children with behavior problems.

The present study examined associations between early parental self-reported psychopathology symptoms and the later behavioral, emotional, and social functioning of preschool children with behavior problems. Mothers and fathers of preschoolers with behavior problems (N = 132; 55 girls, 77 boys) completed parent psychopathology questionnaires when children were 3 years old and completed measures of children's externalizing, internalizing, and social problems annually from age 3 to age 6. The sample included 61% European American, 16% Latino (predominantly Puerto Rican), 10% African American, and 13% multiethnic children. Every dimension of mothers' and fathers' psychopathology symptoms when children were 3 years old was associated with their own reports of children's externalizing and internalizing problems 3 years later. Several dimensions of maternal psychopathology symptoms at age 3 were associated with mother-reported social skills 3 years later. However, the relation between many dimensions of psychopathology symptoms and child outcome appears to be accounted for by co-occurring psychopathology symptoms. Only maternal attention-deficit hyperactivity disorder (ADHD) and Cluster A symptoms, and paternal ADHD and depression/anxiety symptoms emerged as unique predictors of child functioning. These findings suggest that most types of mothers' and fathers' self-reported psychopathology symptoms may play a role in the prognosis of behavioral, social, and emotional outcomes of preschoolers with behavior problems, but that co-occurring symptoms need to be considered.

Self-reported neighborhood stressors and sleep quality among Puerto Rican young adults.

OBJECTIVE: To examine the association between changes in self-reported neighborhood stressors and sleep quality and determine whether this varied by sociocultural context among Puerto Rican young adults. METHODS: Data come from the Boricua Youth Study Health Assessment, a sample of Puerto Rican young adults from San Juan, Puerto Rico, and South Bronx, New York (n = 818; mean age=22.9years). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Neighborhood social stressors (disorder, social cohesion, and safety) were parent-reported in childhood and self-reported in young adulthood and categorized into: low in childhood/young adulthood (reference group), high in childhood/low in young adulthood, low in childhood/high in young adulthood, and high in childhood/young adulthood. Sociocultural context was based on participant residence during childhood (San Juan vs. South Bronx). RESULTS: Adjusting for sociodemographic factors, living with high neighborhood stressors in both childhood and young adulthood (prevalence ratios=1.30, 95% CI: 1.01, 1.66) was associated with overall poor sleep (PSQI score >5). Among PSQI components, living with high neighborhood stressors in young adulthood only or in both time periods was associated with worse subjective sleep quality and daytime dysfunction. Additionally, there were various associations between the neighborhood stressor measures and PSQI components. Results did not differ by sociocultural context. CONCLUSION: Findings suggest that living with high levels of neighborhood stressors during childhood and young adulthood may have a cumulative adverse impact on sleep quality in young adulthood.

Examining the association between prenatal cannabis exposure and child autism traits: A multi-cohort investigation in the environmental influences on child health outcome program.

This study examined the association between prenatal cannabis exposure and autism spectrum disorder (ASD) diagnoses and traits. A total sample of 11,570 children (ages 1-18; 53% male; 25% Hispanic; 60% White) from 34 cohorts of the National Institutes of Health-funded environmental influences on child health outcomes consortium were included in analyses. Results from generalized linear mixed models replicated previous studies showing that associations between prenatal cannabis exposure and ASD traits in children are not significant when controlling for relevant covariates, particularly tobacco exposure. Child biological sex did not moderate the association between prenatal cannabis exposure and ASD. In a large sample and measuring ASD traits continuously, there was no evidence that prenatal cannabis exposure increases the risk for ASD. This work helps to clarify previous mixed findings by addressing concerns about statistical power and ASD measurement.

Association of Maternal Fish Consumption and Omega-3 Supplement Use During Pregnancy With Child Autism-Related Outcomes: Results from a Cohort Consortium Analysis.

BACKGROUND: Prenatal fish intake is a key source of omega-3 polyunsaturated fatty acids needed for brain development, yet intake is generally low, and studies addressing associations with autism spectrum disorder (ASD) and related traits are lacking. OBJECTIVE: To examine associations of prenatal fish intake and omega-3 supplement use with both autism diagnosis and broader autism-related traits. METHODS: Participants were drawn from 32 cohorts in the Environmental influences on Child Health Outcomes (ECHO) Cohort Consortium. Children were born between 1999 and 2019 and part of ongoing follow-up with data available for analysis by August 2022. Exposures included self-reported maternal fish intake and omega-3/fish oil supplement use during pregnancy. Outcome measures included parent report of clinician-diagnosed ASD and parent-reported autism-related traits measured by the Social Responsiveness Scale (SRS)-Second Edition (n=3939 and n=3609 for fish intake analyses, respectively; n=4537 and n=3925 for supplement intake analyses, respectively). RESULTS: In adjusted regression models, relative to no fish intake, fish intake during pregnancy was associated with reduced odds of autism diagnosis (OR=0.84, 95% CI 0.77 to 0.92), and a modest reduction in raw total SRS scores (b=-1.69, 95% CI -3.3 to -0.08). Estimates were similar across categories of fish consumption from "any" or "less than once per week" to "more than twice per week." For omega-3 supplement use, relative to no use, no significant associations with autism diagnosis were identified, whereas a modest relation with SRS score was suggested (ß=1.98, 95% CI 0.33-3.64). CONCLUSIONS: These results extend prior work by suggesting that prenatal fish intake, but not omega-3 supplement use, may be associated with lower likelihood of both autism diagnosis and related traits. Given the low fish intake in the U.S. general population and the rising autism prevalence, these findings suggest the need for better public health messaging regarding guidelines on fish intake for pregnant individuals.

Maternal Mental Health and Offspring Brain Development: An Umbrella Review of Prenatal Interventions.

The idea that risk for psychiatric disorders may be transmitted intergenerationally via prenatal programming places interest in the prenatal period as a critical moment during which intervention efforts may have a strong impact, yet studies testing whether prenatal interventions also protect offspring are limited. The present umbrella review of systematic reviews and meta-analyses (SRMAs) of randomized controlled trials aimed to synthesize the available evidence and highlight promising avenues for intervention. Overall, the literature provides mixed and limited evidence in support of prenatal interventions. Thirty SRMAs were included. Of the 23 SRMAs that reported on prenatal depression interventions, 16 found a significant effect (average standard mean difference = -0.45, SD = 0.25). Similarly, 13 of the 20 SRMAs that reported on anxiety outcomes documented significant reductions (average standard mean difference = -0.76, SD = 0.95 or -0.53/0.53 excluding one outlier). Only 4 SRMAs reported child outcomes, and only 2 (of 10) analyses showed significant effects of prenatal interventions (massage and telephone support on neonatal resuscitation [relative risk = 0.43] and neonatal intensive care unit admissions [relative risk = 0.91]). Notably missing, perhaps due to our strict inclusion criteria (inclusion of randomized controlled trials only), were interventions focusing on key facets of prenatal health (e.g., whole diet, sleep). Structural interventions (housing, access to health care, economic security) were not included, although initial success has been documented in non-SRMAs. Most notably, none of the SRMAs focused on offspring mental health or neurodevelopmental outcomes. Given the possibility that interventions deployed in this period will positively impact the next generation, randomized trials that focus on offspring outcomes are urgently needed.

Prenatal sleep health and risk of offspring ADHD symptomatology and associated phenotypes: a prospective analysis of timing and sex differences in the ECHO cohort.

Background: Sleep difficulties are common in pregnancy, yet poor prenatal sleep may be related to negative long-term outcomes for the offspring, including risk for attention-deficit/hyperactivity disorder (ADHD). Existing studies are few and have not examined timing of exposure effects or offspring sex moderation. We thus aimed to test the hypotheses that poor sleep health in pregnancy is associated with increased risk for ADHD symptoms and offspring sleep problems at approximately 4 years of age. Methods: Participants were 794 mother-child dyads enrolled in the NIH Environmental Influences on Child Health Outcomes Study (ECHO). Participants self-reported on sleep duration, quality, and disturbances during pregnancy and on children's ADHD symptoms and sleep problems on the Child Behaviour Checklist. Findings: Pregnant participants were 32.30 ± 5.50 years and children were 46% female. 44 percent of pregnant participants identified as Hispanic or Latine; 49% identified as White. Second-trimester sleep duration was associated with offspring ADHD symptoms (b = -0.35 [95% CI = -0.57, -0.13], p = 0.026), such that shorter duration was associated with greater symptomatology. Poorer sleep quality in the second trimester was also associated with increased ADHD symptomatology (b = 0.66 [95% CI = 0.18, 1.14], p = 0.037). Greater sleep disturbances in the first trimester were associated with offspring ADHD (b = 1.03 [95% CI = 0.32, 1.03], p = 0.037) and in the second trimester with sleep problems (b = 1.53 [95% CI = 0.42, 2.92], p = 0.026). We did not document substantial offspring sex moderation. Interpretation: Poor prenatal sleep health, particularly quality and duration in the second trimester, may be associated with offspring risk of neurodevelopmental disorders and sleep problems in early childhood. Further research is needed to understand mechanisms, yet our study suggests that prenatal maternal sleep may be a modifiable target for interventions aimed at optimizing early neurodevelopment.

Maternal childhood maltreatment: associations to offspring brain volume and white matter connectivity.

The deleterious effects of adversity are likely intergenerational, such that one generation's adverse experiences can affect the next. Epidemiological studies link maternal adversity to offspring depression and anxiety, possibly via transmission mechanisms that influence offspring fronto-limbic connectivity. However, studies have not thoroughly disassociated postnatal exposure effects nor considered the role of offspring sex. We utilized infant neuroimaging to test the hypothesis that maternal childhood maltreatment (CM) would be associated with increased fronto-limbic connectivity in infancy and tested brain-behavior associations in childhood. Ninety-two dyads participated (32 mothers with CM, 60 without; 52 infant females, 40 infant males). Women reported on their experiences of CM and non-sedated sleeping infants underwent MRIs at 2.44 ± 2.74 weeks. Brain volumes were estimated via structural MRI and white matter structural connectivity (fiber counts) via diffusion MRI with probabilistic tractography. A subset of parents (n = 36) reported on children's behaviors at age 5.17 ± 1.73 years. Males in the maltreatment group demonstrated greater intra-hemispheric fronto-limbic connectivity (b = 0.96, p= 0.008, [95%CI 0.25, 1.66]), no differences emerged for females. Fronto-limbic connectivity was related to somatic complaints in childhood only for males (r = 0.673, p = 0.006). Our findings suggest that CM could have intergenerational associations to offspring brain development, yet mechanistic studies are needed.

Association of Comorbid Behavioral and Medical Conditions With Cannabis Use Disorder in Pregnancy.

Importance: Prenatal cannabis use continues to increase, yet studies of the demographic, psychiatric, and medical characteristics associated with cannabis use in pregnancy are limited by size and use of self-report, and often do not consider cannabis use disorder (CUD) or concomitant substance use disorders (SUDs). Understanding the factors associated with CUD in pregnancy is paramount for designing targeted interventions. Objective: To examine the prevalence of co-occurring psychiatric and medical conditions of US pregnant individuals hospitalized with and without CUD by concomitant SUDs. Design, Setting, and Participants: The study analyzed restricted hospital discharge data from the 2010 to 2018 Healthcare Cost and Utilization Project State Inpatient Databases in 35 states. Data were analyzed from January to August 2021. Weighted linear regressions tested whether the prevalence of psychiatric and medical conditions differed between individuals with and without a CUD diagnosis at hospitalization. Inpatient hospitalizations of pregnant patients aged 15 to 44 years with a CUD diagnosis were identified. Pregnant patients aged 15 to 44 years without a CUD diagnosis were identified for comparison. Patients were further stratified based on concomitant SUD patterns: (1) other SUDs, including at least 1 controlled substance; (2) other SUDs, excluding controlled substances; and (3) no other SUDs. Exposures: CUD in pregnancy. Main Outcomes and Measures: Prevalence of demographic characteristics, psychiatric disorders (eg, depression and anxiety), and medical conditions (eg, epilepsy and vomiting). Results: The sample included 20 914 591 hospitalizations of individuals who were pregnant. The mean (SD) age was 28.24 (5.85) years. Of the total number of hospitalizations, 249 084 (1.19%) involved CUD and 20 665 507 (98.81%) did not. The proportion of prenatal hospitalizations involving CUD increased from 0.008 in 2010 to 0.02 in 2018. Analyses showed significant differences in the prevalence of almost every medical and psychiatric outcome examined between hospitalizations with and without CUD diagnoses, regardless of concomitant SUDs. Elevations were seen in depression (0.089; 95% CI, 0.083-0.095), anxiety (0.072; 95% CI, 0.066-0.076), and nausea (0.036; 95% CI, 0.033-0.040]) among individuals with CUD only at hospitalization compared with individuals with no SUDs at hospitalization. Conclusions and Relevance: Considerable growth was observed in the prevalence of CUD diagnoses among individuals hospitalized prenatally and in the prevalence of depression, anxiety, nausea, and other conditions in individuals with CUD at hospitalization. This study highlights the need for more screening, prevention, and treatment, particularly in populations with co-occurring CUD and psychiatric disorders. Research on the determinants and outcomes associated with CUD during pregnancy is needed to guide clinicians, policy makers, and patients in making informed decisions.

Neural Activity and Emotion Socialization as Predictors of Later Emotion Regulation Difficulties in Children With and Without Hyperactivity/Impulsivity.

OBJECTIVE: This study examined emotion socialization and neural activity during frustration as predictors of emotion regulation (ER) difficulties, and the interplay of emotion socialization and neural activity, in children with and without hyperactivity/impulsivity (H/I). METHOD: At Time 1, neural activity (P1, N2, P3) during a frustration task, H/I symptoms, and emotion socialization were assessed in 68 children (aged 4-7 years old). At Time 2 (1.5-2 years later), child-report, maternal-report, and observation measures of ER difficulties were assessed. RESULTS: H/I symptoms moderated the relation between predictors and ER difficulties; there were significant relations for children with high, but not low, levels of H/I. Further, as emotion socialization quality increased, relations between event-related potentials and later ER difficulties became weaker. CONCLUSION: The processes underlying ER difficulties differ for children with H/I symptoms. High quality emotion socialization may have a protective effect for children whose neural patterns indicate risk for later ER difficulties.

The Intergenerational Impact of Structural Racism and Cumulative Trauma on Depression.

Depression among individuals who have been racially and ethnically minoritized in the United States can be vastly different from that of non-Hispanic White Americans. For example, African American adults who have depression rate their symptoms as more severe, have a longer course of illness, and experience more depression-associated disability. The purpose of this review was to conceptualize how structural racism and cumulative trauma can be fundamental drivers of the intergenerational transmission of depression. The authors propose that understanding risk factors for depression, particularly its intergenerational reach, requires accounting for structural racism. In light of the profoundly different experiences of African Americans who experience depression (i.e., a more persistent course of illness and greater disability), it is critical to examine whether an emerging explanation for some of these differences is the intergenerational transmission of this disorder due to structural racism.

Racial/ethnic disparities in subjective sleep duration, sleep quality, and sleep disturbances during pregnancy: an ECHO study.

In the United States, racial/ethnic minoritized groups experience worse sleep than non-Hispanic Whites (nHW), but less is known about pregnant people. This is a key consideration since poor sleep during pregnancy is common and associated with increased risk of adverse perinatal outcomes. This study reports the prevalence of subjective sleep measures in a multi-racial/ethnic pregnant population from the Environmental influences on Child Health Outcomes (ECHO) program. Participants' self-reported race and ethnicity were grouped into: nHW, non-Hispanic Black/African American (nHB/AA), Hispanic, non-Hispanic Asian (nHA). Analyses examined trimester-specific (first (T1), second (T2), third (T3)) nocturnal sleep duration, quality, and disturbances (Pittsburgh Sleep Quality Index and ECHO maternal sleep health questionnaire). Linear or multinomial regressions estimated the associations between race/ethnicity and each sleep domain by trimester, controlling for body mass index and age, with nHW as reference group. We repeated analyses within maternal education strata. nHB/AA participants reported shorter sleep duration (T2: ß = -0.55 [-0.80,-0.31]; T3: ß = -0.65 [-0.99,-0.31]) and more sleep disturbances (T2: ß = 1.92 [1.09,2.75]; T3: ß = 1.41 [0.09,2.74]). Hispanic participants reported longer sleep duration (T1: ß = 0.22 [0.00004,0.44]; T2: ß = 0.61 [0.47,0.76]; T3: ß = 0.46 [0.22,0.70]), better sleep quality (Reference group: Very good. Fairly good T1: OR = 0.48 [0.32,0.73], T2: OR = 0.36 [0.26,0.48], T3: OR = 0.31 [0.18,0.52]. Fairly bad T1: OR = 0.27 [0.16,0.44], T2: OR = 0.46 [0.31, 0.67], T3: OR = 0.31 [0.17,0.55]), and fewer sleep disturbances (T2: ß = -0.5 [-1.0,-0.12]; T3: ß = -1.21 [-2.07,-0.35]). Differences persisted within the high-SES subsample. Given the stark racial/ethnic disparities in perinatal outcomes and their associations with sleep health, further research is warranted to investigate the determinants of these disparities.

Behavioral and Neural Markers of Emotion Competence as Predictors of Later Psychopathology in Children With and Without Hyperactive/Impulsive Symptoms.

Objective: We examined behavioral and neural markers of emotion competence in young children as predictors of psychopathology, and as mediators of the relation between hyperactivity/impulsivity (H/I) and psychopathology. Method: At Time 1 (T1), children (n = 49; ages 4-7 years) with and without H/I symptoms completed a frustration task. Frustration, observed emotion, and neural activity (P1, N2, and P3 event-related potentials) were measured. Symptoms of psychopathology were collected 18 months later (Time 2; T2). Results: T1 lability, negative affect, and frustration predicted T2 depression and aggression symptomatology, controlling for T1 symptoms. Children with difficulty allocating neural resources during and after frustration were at risk for depression, aggression, and anxiety symptoms, controlling for earlier symptoms. P3 amplitudes during recovery mediated the relation between H/I and later depression. Conclusion: Markers of emotion competence contribute to psychopathology symptoms, particularly in children at risk for attention-deficit/hyperactivity disorder (ADHD). Emotion competence skills may be useful intervention targets.

Differences in brain structure and function in children with the FTO obesity-risk allele.

OBJECTIVE: Noncoding alleles of the fat mass and obesity-associated (FTO) gene have been associated with obesity risk, yet the underlying mechanisms remain unknown. Risk allele carriers show alterations in brain structure and function, but previous studies have not disassociated the effects of genotype from those of body mass index (BMI). METHODS: Differences in brain structure and function were examined in children without obesity grouped by their number of copies (0,1,2) of the FTO obesity-risk single-nucleotide polymorphism (SNP) rs1421085. One hundred five 5- to 10-year-olds (5th-95th percentile body fat) were eligible to participate. Usable scans were obtained from 93 participants (15 CC [homozygous risk], 31 CT [heterozygous] and 47 TT [homozygous low risk]). RESULTS: Homozygous C allele carriers (CCs) showed greater grey matter volume in the cerebellum and temporal fusiform gyrus. CCs also demonstrated increased bilateral cerebellar white matter fibre density and increased resting-state functional connectivity between the bilateral cerebellum and regions in the frontotemporal cortices. CONCLUSIONS: This is the first study to examine brain structure and function related to FTO alleles in young children not yet manifesting obesity. This study lends support to the notion that the cerebellum may be involved in FTO-related risk for obesity, yet replication and further longitudinal study are required.
