Procedural abortion, provider-initiated preterm delivery and survival in pregnant people with cancer: A population-based cohort study.

OBJECTIVE: To assess whether procedural-induced abortion or provider-initiated preterm delivery are associated with improved survival in pregnant people with cancer. DESIGN: Retrospective population-based cohort study. SETTING: Provinces of Alberta and Ontario, Canada, 2003-2016. POPULATION: Females aged 18-50 years diagnosed with cancer at <20 weeks' (for the assessment of procedural-induced abortion) or <37 weeks' gestation (for the assessment of provider-initiated delivery). METHODS: Cox proportional hazard models assessed all-cause mortality in relation to procedural-induced abortion and provider-initiated preterm delivery, adjusting for cancer site, stage at diagnosis and age. Meta-analysis pooled the results across both provinces. MAIN OUTCOME MEASURES: All cause mortality. RESULTS: There were 512 pregnant people diagnosed with cancer at <20 weeks' gestation and 782 diagnosed with cancer at <37 weeks' gestation. Neither procedural-induced abortion (adjusted hazard ratio [aHR] = 1.39, 95% CI: 0.32-6.17) nor provider-initiated preterm delivery (aHR = 1.17, 95% CI: 0.76-1.81) were associated with improved survival following adjustment for age, stage at diagnosis and cancer site. CONCLUSIONS: Neither procedural-induced abortion nor provider-initiated preterm birth was associated with improved survival in pregnant people diagnosed with cancer; however, these obstetric interventions are highly personal decisions best decided by the pregnant person in consultation with their care providers.

Childcare use and the social-emotional and behavioural outcomes of late-preterm and early-term born children at age 5: An analysis of the All Our Families longitudinal cohort.

OBJECTIVES: Gestational age at birth (GA) shows an inverse gradient of risk with social-emotional and behavioural outcomes among children born late preterm (≥ 34 and < 37 weeks) and early term (≥ 37 and < 39 weeks). Childcare has the potential to influence this association. This study aimed to estimate the association between GA and social-emotional/behavioural problems among children born between ≥ 34 and < 41 weeks gestation, determine whether this association was modified by childcare use, and describe the relationship between childcare and behavioural and social-emotional functioning at age 5. METHODS: Using data from the All Our Families cohort (n = 1324), logistic regression models were used to model the association between GA and social-emotional/behavioural problems (BASC-2 composite scales at age 5). Models were fit with interaction terms between GA and childcare variables (amount, multiplicity, and type of childcare at age 3) to assess effect modification. RESULTS: GA showed no significant associations with social-emotional/behavioural problems at age 5, though the type of childcare significantly modified the association between GA and externalizing and internalizing problems. Neither the number of hours spent in childcare (amount) nor the number of childcare arrangements used (multiplicity) modified the association between GA and social-emotional/behavioural problems. However, multiplicity was associated with externalizing behavioural problems (aOR = 2.09, 95% CI 1.14‒3.83). CONCLUSION: This study found no significant association between GA and social-emotional/behavioural problems at age 5, though childcare type modified this association. Factors such as using multiple childcare arrangements to meet families' childcare needs have the potential to influence a child's social-emotional and behavioural functioning at age 5.

RéSUMé: OBJECTIFS: L'âge gestationnel à la naissance (AG) présente un gradient du risque inversé pour les résultats socioaffectifs et comportementaux entre les naissances prématurées tardives (entre ≥ 34 et < 37 semaines) et les naissances précoces (entre ≥ 37 et < 39 semaines). Les services de garde pourraient influencer cette association. Notre étude visait à estimer l'association entre l'AG et les troubles socioaffectifs/comportementaux chez les enfants nés entre ≥ 34 et < 41 semaines de gestation, à déterminer si cette association est modifiée par le recours aux services de garde et à décrire la relation entre les services de garde et le fonctionnement comportemental et socioaffectif à l'âge de cinq ans. MéTHODE: Des modèles de régression logistique utilisant les données de la cohorte All Our Families (n = 1 324) ont servi à modéliser l'association entre l'AG et les troubles socioaffectifs/comportementaux (échelles composées BASC-2 à l'âge de cinq ans). Les modèles ont été ajustés avec des paramètres d'interaction entre l'AG et les variables des services de garde (nombre, multiplicité et type de services de garde à l'âge de trois ans) pour évaluer les facteurs modifiant l'effet. RéSULTATS: L'AG n'a présenté aucune association significative avec les troubles socioaffectifs/comportementaux à l'âge de cinq ans, mais le type de services de garde a sensiblement modifié l'association entre l'AG et les troubles d'extériorisation et d'intériorisation. Ni le nombre d'heures passées dans les services de garde (nombre), ni le nombre de modes de garde d'enfants utilisés (multiplicité) n'ont modifié l'association entre l'AG et les troubles socioaffectifs/comportementaux. Toutefois, la multiplicité était associée aux troubles comportementaux d'extériorisation (RCa = 2,09, IC de 95% : 1,14‒3,83). CONCLUSION: L'étude n'a trouvé aucune association significative entre l'AG et les troubles socioaffectifs/comportementaux à l'âge de cinq ans, mais le type de services de garde a modifié cette association. Des facteurs comme le recours à plusieurs modes de garde d'enfants pour combler les besoins de services de garde de la famille pourraient influencer le fonctionnement socioaffectif et comportemental d'un enfant à l'âge de cinq ans.

Secondary and Tertiary Prevention for Adolescent Dating Violence: A Systematic Review.

Adolescent dating violence (ADV) is a pervasive public health issue associated with numerous social, psychological, and physical health consequences. Thus, programs are often implemented to prevent ADV and promote healthy relationships. Although there is a growing body of literature on primary ADV prevention strategies (i.e., prevention), little is known about secondary (e.g., early intervention) and tertiary (e.g., manage and reduce impact once occurring) ADV prevention approaches. This systematic review, guided by Cochrane Review methodology, summarizes available evidence on secondary and tertiary ADV preventive interventions. The search had no date restriction and was conducted in eight databases in November 2022. Studies published in English and/or Spanish were included if they described the development, implementation, and/or evaluation of a secondary and/or tertiary preventive intervention for ADV. After screening the titles and abstracts of 3,645 articles, 31 articles were included in this study, reporting on 14 secondary, 3 primary/secondary, 6 secondary/tertiary, and 1 tertiary ADV preventive intervention. The included studies highlighted that available secondary ADV prevention strategies are quite effective in preventing ADV victimization and perpetration, and that the effects may be strongest for teens with a higher risk of being involved in an abusive relationship. The only included study that reported on a tertiary intervention was a program development study. Based on the lack of tertiary prevention strategies available for ADV, clinical interventions focusing on treating and reducing negative consequences after ADV are needed.

Development and validation of the Cannabis Exposure in Pregnancy Tool (CEPT): a mixed methods study.

BACKGROUND: Evidence of associations between prenatal cannabis use (PCU) and maternal and infant health outcomes remains conflicting amid broad legalization of cannabis across Canada and 40 American states. A critical limitation of existing evidence lies in the non-standardized and crude measurement of prenatal cannabis use (PCU), resulting in high risk of misclassification bias. We developed a standardized tool to comprehensively measure prenatal cannabis use in pregnant populations for research purposes. METHODS: We conducted a mixed-methods, patient-oriented tool development and validation study, using a bias-minimizing process. Following an environmental scan and critical appraisal of existing prenatal substance use tools, we recruited pregnant participants via targeted social media advertising and obstetric clinics in Alberta, Canada. We conducted individual in-depth interviews and cognitive interviewing in separate sub-samples, to develop and refine our tool. We assessed convergent and discriminant validity internal consistency and 3-month test-retest reliability, and validated the tool externally against urine-THC bioassays. RESULTS: Two hundred fifty four pregnant women participated. The 9-item Cannabis Exposure in Pregnancy Tool (CEPT) had excellent discriminant (Cohen's kappa = -0.27-0.15) and convergent (Cohen's kappa = 0.72-1.0) validity; as well as high internal consistency (Chronbach's alpha = 0.92), and very good test-retest reliability (weighted Kappa = 0.92, 95% C.I. [0.86-0.97]). The CEPT is valid against urine THC bioassay (sensitivity = 100%, specificity = 82%). CONCLUSION: The CEPT is a novel, valid and reliable measure of frequency, timing, dose, and mode of PCU, in a contemporary sample of pregnant women. Using CEPT (compared to non-standardized tools) can improve measurement accuracy, and thus the quality of research examining PCU and maternal and child health outcomes.

Peer Victimization, Posttraumatic Stress Symptoms, and Chronic Pain: A Longitudinal Examination.

Chronic pain and posttraumatic stress disorder symptoms (PTSS) co-occur at high rates in youth and are linked to worse pain outcomes and quality of life. While peer victimization has been posited as a mechanism underlying the PTSS-pain relationship in youth, empirical evidence suggests that it may exacerbate both PTSS and pain. The present study aimed to longitudinally examine PTSS as a mediator in the relationship between peer victimization at baseline and pain-related outcomes at 3 months in youth with chronic pain. Participants included 182 youth aged 10 to 18 years recruited from a tertiary-level children's hospital in Western Canada. At baseline, participants completed measures to assess pain (intensity and interference), peer victimization (relational and overt), and PTSS. The pain was reassessed at a 3-month follow-up. Primary hypotheses were tested utilizing a series of mediation analyses with PTSS as a proposed mediator in the associations between peer victimization and pain outcomes. Youth PTSS mediated the relationship between higher baseline relational victimization and higher 3-month pain interference while controlling for baseline pain interference. Three-month pain intensity was not correlated with peer victimization; thus, pain intensity was not included in the analyses. These findings reveal that PTSS may be an underlying factor in the co-occurrence of peer victimization and chronic pain in youth. Further research is needed to better understand the role of peer victimization in the maintenance of chronic pain to ensure appropriate, effective, and timely interventions that address the social and mental health issues impacting the lives of these youth as well as their pain. PERSPECTIVE: PTSS may be an underlying factor in the co-occurrence between peer victimization and chronic pain in youth, highlighting the need to assess for both peer relationship problems and PTSS in youth with chronic pain.

Sex and age effects on gray matter volume trajectories in young children with prenatal alcohol exposure.

Prenatal alcohol exposure (PAE) occurs in ~11% of North American pregnancies and is the most common known cause of neurodevelopmental disabilities such as fetal alcohol spectrum disorder (FASD; ~2-5% prevalence). PAE has been consistently associated with smaller gray matter volumes in children, adolescents, and adults. A small number of longitudinal studies show altered gray matter development trajectories in late childhood/early adolescence, but patterns in early childhood and potential sex differences have not been characterized in young children. Using longitudinal T1-weighted MRI, the present study characterized gray matter volume development in young children with PAE (N = 42, 84 scans, ages 3-8 years) compared to unexposed children (N = 127, 450 scans, ages 2-8.5 years). Overall, we observed altered global and regional gray matter development trajectories in the PAE group, wherein they had attenuated age-related increases and more volume decreases relative to unexposed children. Moreover, we found more pronounced sex differences in children with PAE; females with PAE having the smallest gray matter volumes and the least age-related changes of all groups. This pattern of altered development may indicate reduced brain plasticity and/or accelerated maturation and may underlie the cognitive/behavioral difficulties often experienced by children with PAE. In conjunction with previous research on older children, adolescents, and adults with PAE, our results suggest that gray matter volume differences associated with PAE vary by age and may become more apparent in older children.

The feasibility of an adapted virtual mindfulness intervention for Special Olympics athletes and their caregivers.

BACKGROUND: Virtual mindfulness may be helpful for individuals with intellectual disabilities in the context of COVID-related disruptions of in-person programming, such as Special Olympics (SO). This study examined the feasibility of a virtual mindfulness intervention for SO athletes and their caregivers. METHOD: SO athletes (n = 44) and their caregivers (n = 29) participated in a 6-week adapted virtual mindfulness intervention. Athletes completed mindfulness and well-being questionnaires prior to, immediately following, and 3-months post-intervention. Caregivers completed questionnaires assessing their own stress, mindfulness, and well-being, as well as athlete mental health. Exit interviews were conducted immediately following the intervention. RESULTS: The intervention was feasible in terms of demand, implementation, acceptability, and limited testing efficacy. There were significant improvements in athlete well-being and mental health, and caregiver stress and mindfulness post-intervention. CONCLUSIONS: Adapted virtual mindfulness groups may be an effective intervention in improving the well-being of adults with intellectual disabilities and their caregivers.

A comparison of psychiatric inpatient admissions in youth before and during the COVID-19 pandemic.

Background: The current understanding of the effect of COVID-19 on child and youth admissions to psychiatric inpatient units over time is limited, with conflicting findings and many studies focusing on the initial wave of the pandemic. Objectives: This study identified changes in psychiatric inpatient admissions, and reasons for admission, including suicidality and self-harm, before and during the COVID-19 pandemic. Method: This time series study analyzed 3,723 admissions of youth (ages 0-18.88 years) admitted to four major psychiatry inpatient units in a large Canadian city between January 1st, 2016 and December 31st, 2021. Pre-pandemic (before March 11, 2020) and during-pandemic (after March 11, 2020) trends of admissions were explored using a Bayesian structural time series model (BSTS). Results: The model revealed that overall admissions during the pandemic period exceeded what would have been predicted in the absence of a pandemic, a relative increase of 29%. Additionally, a rise in the total number of admissions due to self-harm and suicidality (29% increase), externalizing/behavioral issues (69% increase), and internalizing/emotional issues (28% increase) provided strong evidence of increased admissions compared to what might have been expected from pre-pandemic numbers. Conclusions: There was strong evidence of increases in psychiatric inpatient admissions during the COVID-19 pandemic compared to expected trends based on pre-pandemic data. To ensure accessible and continuous mental health supports and services for youth and their families during future pandemics, these findings highlight the need for rapid expanse of inpatient mental health services, similar to what occurred in many intensive care units across Canada.

Contexte: La compréhension actuelle de l'effet de la COVID-19 sur les enfants et jeunes patients admis aux unités d'hospitalisation psychiatrique avec le temps est limitée, avec des conclusions contradictoires et des études portant sur la vague initiale de la pandémie. Objectifs: La présente étude a identifié les changements dans les admissions de patients hospitalisés en psychiatrie, et les raisons de l'admission, notamment la suicidabilité et l'automutilation, avant et durant la pandémie de la COVID-19. Méthode: Cette étude de séries chronologiques a analysé 3 723 admissions de jeunes (de 0 à 18,88 ans) admis à quatre grandes unités d'hospitalisation en psychiatrie dans une grande ville canadienne entre le 1er janvier 2016 et le 31 décembre 2021. Les tendances des admissions pré-pandémiques (avant le 11 mars 2020) et pendant la pandémie (après le 11 mars 2020) ont été explorées à l'aide d'un Modèle bayésien de séries chronologiques structurelles (BSTS). Résultats: Le modèle a révélé que globalement, les admissions durant la période pandémique excédaient ce qui aurait été prédit en l'absence d'une pandémie, une hausse relative de 29%. En outre, une hausse du nombre total d'admissions attribuables à l'automutilation et à la suicidabilité (hausse de 29%), à des problèmes de comportement/d'externalisation (hausse de 69%), et à des problèmes d'internalisation/émotionnels (hausse de 28%) a fourni des preuves solides des admissions accrues comparé à ce qu'on aurait pu attendre des chiffres pré-pandémiques. Conclusions: Il y avait des preuves solides des augmentations des admissions de patients hospitalisés en psychiatrie durant la pandémie de la COVID19 comparé aux tendances prévues selon les données pré-pandémiques. Afin d'assurer des soutiens et des services de santé mentale accessibles et continus pour les jeunes et leur famille durant les futures pandémies, ces résultats soulignent la nécessité d'une expansion rapide des services de santé mentale pour patients hospitalisés, pareillement à ce qui s'est produit dans de nombreuses unités de soins intensifs du Canada.

A systematic review of self and observer assessment of pain and related functioning in youth with brain-based developmental disabilities.

ABSTRACT: Pain experiences of youth with brain-based developmental disabilities are often overlooked and/or misinterpreted, increasing the risk for poor or inadequate pain assessment and management. Ample measures exist to assess acute and chronic pain, yet their utility and frequency of use in youth with brain-based developmental disabilities is unclear and available measures do not have strong measurement properties for this diverse group. This systematic review identified the scope of self-reported and observer-reported pain assessment in studies of youth (aged 3-24 years) with brain-based developmental disabilities (phase 1) and summarized other measures of pain-related functioning for acute and chronic pain (ie, physical, emotional, social, sleep, and quality of life, within the subset of quantitative studies focused primarily on pain, phase 2). A comprehensive search for English-language studies was conducted in August 2022 in Web of Science, CINAHL, MEDLINE, Cochrane CENTRAL, EMBASE, and APA PsychINFO (PROSPERO registration: CRD42021237444). A total of 17,029 unique records were screened. Of the 707 articles included in phase 1, most assessed chronic pain (n = 314; 62.0%) and primarily used observer-report (n = 155; 31%) over self-report (n = 67; 13%). Of the 137 articles included in phase 2, other outcomes assessed alongside pain intensity included motor ability (16.8%), adaptive functioning (11%), quality of life (8%), pain interference (6.6%), mental health (5.8%), and communication ability (2.9%). Cerebral palsy was the most common population in both phase 1 (n = 343; 48.5%) and phase 2 (n = 83; 59.7%). This review provides a foundational understanding of pain assessment in brain-based developmental disabilities and highlights continued inequities in holistic pain assessment for this population.

COVID-19 and Neurodevelopmental Disabilities: Examining the Impact of the First 2 Years of the Pandemic on the Demand for Pediatric Inpatient Care.

The COVID-19 pandemic has strained the resources of the world's healthcare systems. Most individuals with neurodevelopmental disabilities (NDDs) experience significant mental health issues and face substantial barriers in accessing appropriate supports which have been exacerbated during the pandemic. It is unknown the extent to which COVID-19 impacted the demand for and effectiveness of inpatient care for those with NDDs. The impact of COVID-19 on the number of admissions of youth with NDDs to pediatric inpatient psychiatry units, as well as their functioning and length of stay during the first two years of the pandemic was analyzed using Bayesian structural time series models. Admission data of youth with NDDs from four pediatric inpatient units in Alberta, Canada (n = 2144) was examined. Inpatient admissions of youth with NDDs significantly increased following the onset of the pandemic. Compared to the period prior to the pandemic, patients with NDDs had significantly worse overall functioning and received fewer days of treatment. These findings highlight the need for increased resources to support the mental health needs of this vulnerable population and are consistent with other studies in the general population examining the utilization of inpatient psychiatric units during the pandemic.

Factors predicting general health concerns and atypical behaviours in children with prenatal alcohol exposure and other adverse exposures.

Background: Prenatal alcohol exposure (PAE) can have significant negative consequences on the health outcomes of children. Children with PAE often experience other prenatal and postnatal adverse exposures. Increased rates of general health concerns and atypical behaviours are seen in both children with PAE as well as with other patterns of adverse exposures, although these have not been systematically described. The association between multiple adverse exposures and adverse health concerns and atypical behaviours in children with PAE is unknown. Methods: Demographic information, medical history, adverse exposures, health concerns, and atypical behaviours were collected from children with confirmed PAE (n = 22; 14 males, age range = 7.9-15.9 years) and their caregivers. Support vector machine learning classification models were used to predict the presence of health concerns and atypical behaviours based on adverse exposures. Associations between the sums of adverse exposures, health concerns, and atypical behaviours were examined using correlation analysis. Results: All children experienced health concerns, the most common being sensitivity to sensory inputs (64%; 14/22). Similarly, all children engaged in atypical behaviours, with atypical sensory behaviour (50%; 11/22) being the most common. Prenatal alcohol exposure was most important factor for predicting some health concerns and atypical behaviours, and alone and in combination with other factors. Simple associations between adverse exposures could not be identified for many health concerns and atypical behaviours. Conclusion: Children with PAE and other adverse exposures experience high rates of health concerns and atypical behaviours. This study demonstrates the complex effects of multiple adverse exposures on health and behaviour in children.

Long-term Mortality in Individuals Diagnosed With Cancer During Pregnancy or Postpartum.

Importance: Outcomes among patients with pregnancy-associated cancers (diagnosed during pregnancy or 1-year postpartum) other than breast cancer have received relatively little research attention. High-quality data from additional cancer sites are needed to inform the care of this unique group of patients. Objective: To assess mortality and survival in premenopausal women with pregnancy-associated cancers, with a particular focus on cancers other than those of the breast. Design, Setting, and Participants: This population-based retrospective cohort study included premenopausal women (aged 18-50 years) living in 3 Canadian provinces (Alberta, British Columbia, and Ontario) diagnosed with cancer between January 1, 2003, and December 31, 2016, with follow-up until December 31, 2017, or date of death. Data analysis occurred in 2021 and 2022. Exposures: Participants were categorized as being diagnosed with cancer during pregnancy (from conception to delivery), during the postpartum period (up to 1 year after delivery), or during a time that was remote from pregnancy. Main Outcomes and Measures: Outcomes were overall survival at 1 and 5 years and time from diagnosis to death due to any cause. Cox proportional hazard models were used to estimate mortality adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs), adjusting for age at cancer diagnosis, cancer stage, cancer site, and days from diagnosis to first treatment. Meta-analysis was used to pool results across all 3 provinces. Results: During the study period there were 1014, 3074, and 20 219 participants diagnosed with cancer during pregnancy, postpartum, and periods remote from pregnancy, respectively. One-year survival was similar across the 3 groups, but 5-year survival was lower among those diagnosed with cancer during pregnancy or postpartum. Overall, there was a greater risk of death due to pregnancy-associated cancer among those diagnosed during pregnancy (aHR, 1.79; 95% CI, 1.51-2.13) and postpartum (aHR, 1.49; 95% CI, 1.33-1.67); however, these results varied across cancer sites. Increased hazard of mortality was observed for breast (aHR, 2.01; 95% CI, 1.58-2.56), ovarian (aHR, 2.60; 95% CI, 1.12-6.03), and stomach (aHR, 10.37; 95% CI, 3.56-30.24) cancers diagnosed during pregnancy, and brain (aHR, 2.75; 95% CI, 1.28-5.90), breast (aHR, 1.61; 95% CI, 1.32-1.95), and melanoma (aHR, 1.84; 95% CI, 1.02-3.30) cancers diagnosed postpartum. Conclusions and Relevance: This population-based cohort study found that pregnancy-associated cancers had increased overall 5-year mortality, though not all cancer sites presented the same risk.

Autistic characteristics and mental health symptoms in autistic youth during the first COVID-19 wave in Canada.

Autistic youth are at heightened risk for mental health issues, and pandemic-related stressors may exacerbate this risk. This study (1) described caregiver-reported youth mental health prior to and during the pandemic; and (2) explored individual, caregiver, and environmental factors associated with changes in autistic characteristics, social-emotional symptoms, and overall mental health. 582 caregivers of autistic children (2-18 years old) completed an online survey between June and July 2020 in which they provided demographic information, their child's pre-COVID and current mental health, autistic characteristics, and social-emotional symptoms. Caregivers also rated their own perceived stress, and COVID-related household and service disruption. According to caregivers, youth experienced more autistic characteristics and social-emotional concerns during the pandemic. Autistic youth were also reported to experience poorer overall mental health during the pandemic than before the pandemic. Older youth whose caregiver's indicated higher perceived stress and greater household disruption were reported to experience more autistic traits during pandemic. Caregiver-reported increases in youth social-emotional symptoms (i.e., behavior problems, anxiety, and low mood) was associated with being older, the presence of a pre-existing mental health condition, higher caregiver stress, and greater household and service disruption. Finally, experiencing less household financial hardship prior to COVID-19, absence of a pre-existing psychiatric condition, less caregiver stress, and less service disruption were associated with better youth pandemic mental health. Strategies to support the autistic community during and following the pandemic need to be developed. The developmental-ecological factors identified in this study could help target support strategies to those autistic youth who are most vulnerable to mental health problems.

The association of gestational age at birth with trajectories of early childhood developmental delay among late preterm and early term born children: A longitudinal analysis of All Our Families pregnancy cohort.

BACKGROUND: Like infants born very preterm (<32 weeks), late preterm (≥34 and <37 weeks) and early term (≥37 and <39 weeks) births have been associated with increased risk of developmental delay (DD); yet, the evidence remains heterogeneous across the continuum of gestational ages, hindering early identification and intervention. OBJECTIVE: To estimate the association of gestational age at birth with early childhood trajectories of DD in early childhood for infants born ≥34 and <41 weeks, and determine how various maternal, pregnancy and infant characteristics relate to these trajectory groups. METHODS: Analysis of mother-child dyad data with infants born ≥34 and <41 weeks gestational age within an observational pregnancy cohort in Alberta, Canada, from 2008 to 2011 (n = 2644). The association between gestational age and trajectories of the total number of Ages and Stages Questionnaire domains indicating risk of DD from 1 through 5 years of age were estimated using group-based trajectory modelling along with other perinatal risk factors. RESULTS: Three distinct trajectory groups were identified: low-risk, moderate-risk (transiently at risk of DD in one domain over time) and high-risk (consistently at risk of delay in ≥2 domains over time). Per week of decreasing gestational age, the risk ratio of membership in the high-risk group increases by 1.77 (95% confidence interval [CI] 1.43, 2.20) or 1.84 (95% CI 1.49, 2.27) relative to the moderate-risk and low-risk respectively. Increasing maternal age, identifying as Black, indigenous or a person of colour, elevated maternal depressive symptoms in pregnancy, and male infant sex were associated with high- and moderate-risk trajectories compared to the low-risk trajectory. CONCLUSIONS: In combination with decreasing gestational age, poor maternal mental health and social determinants of health increase the probability of membership in trajectories with increased risk of DD, suggesting that additional monitoring of children born late preterm and early term is warranted.

Effect of Remote Peer-Counsellor- delivered Behavioral Activation and Peer-support for Antenatal Depression on Gestational Age at Delivery: a single-blind, randomized control trial.

BACKGROUND: Antenatal depression (AD) is the most common complication of pregnancy in developed countries and increases the risk of preterm birth (PTB). Many pregnant individuals with AD do not obtain treatment due in part to risks associated with antidepressant medications, the expense and wait times for psychological services, and perceived stigma. Accessible and timely treatment of antenatal depression is crucial to minimize foetal impacts and associated long-term child health outcomes. Previous studies show that behavioural activation and peer support are promising avenues of treatment for perinatal depression. Additionally, remote and paraprofessional counselling interventions show promise as more accessible, sustainable, and cost-effective treatment avenues than traditional psychological services. The primary aim of this trial is to test the effectiveness of a remote, behavioural activation and peer support intervention, administered by trained peer para-professionals, for increasing gestational age at delivery among those with antenatal depression. The secondary aims are to evaluate the effectiveness for treating AD prior to delivery, with persistence into the postpartum; improving anxiety symptoms; and improving parenting self-efficacy compared to controls. METHODS: A two-arm, single-blinded, parallel groups randomized controlled trial (RCT) with repeated measures will be conducted. Participants scoring >10 on the Edinburgh Postnatal Depression Scale will be recruited from the larger P3 cohort and invited to enroll. Assessments will be conducted prior to 27 weeks' gestation at trial intake (T1), post-intervention, prior to delivery (T2), 5-6 months postpartum (T3), and 11-12 months postpartum (T4) and will include self-report questionnaires and linked medical records. DISCUSSION: Our remote, peer paraprofessional-delivered behavioural activation plus peer support intervention has the potential to successfully reduce symptoms of AD, which may in turn decrease the risk of PTB and subsequent health impacts. The current trial builds on previous findings and uses a patient-oriented approach to address priorities for patient care and to provide a cost-effective, accessible, and evidence-based treatment to pregnant individuals with AD.

Development and validation of the Social Reward Questionnaire-Early Childhood.

Social interactions like group inclusion, receiving praise, or treating others kindly can be motivating and enjoyable. Social reward sensitivity, including motivation and enjoyment, varies between individuals. In early childhood, this variation may relate to differences in social experience and development. Social reward questionnaires have been developed to measure individual differences in social enjoyment for adolescents and adults, but no early childhood measure currently exists. Here, we describe the development and validation of the parent/caregiver report Social Reward Questionnaire-Early Childhood (SRQ-EC) for children aged 3-7 years. The SRQ-EC was developed to quantify both wanting (motivation) and liking (enjoyment) of social rewards, which were considered in separate factor models. For wanting and liking models, exploratory (N = 126) and confirmatory (N = 344) factor analyses identified that three subscales best represented early childhood social reward sensitivity, which were: Sociability (large groups), Admiration (praise and positive attention), and Prosocial Interactions and Compliance (kindness and rule following). SRQ-EC subscales were internally consistent (ω = 0.76-0.91, α = 0.75-0.88, mean interitem correlations = 0.38-0.60) with high test-retest reliability over 2-weeks (r = 0.66-0.85, all p < .001). Subscales differentially associated with other social behavior and personality measures, suggesting construct validity. SRQ-EC subscale scores further showed differential and significant associations with autistic-like traits in nonautistic children. These results suggest that SRQ-EC subscale scores are reliable for assessing social reward sensitivity during early childhood, which could offer key developmental insight regarding interindividual variation in early social behavior.

Atypical Tactile Perception in Early Childhood Autism.

We assessed different aspects of tactile perception in young children (3-6 years) with autism. Autistic and neurotypical children completed vibrotactile tasks assessing reaction time, amplitude discrimination (sequential and simultaneous) and temporal discrimination (temporal order judgment and duration discrimination). Autistic children had elevated and more variable reaction times, suggesting slower perceptual-motor processing speed and/or greater distractibility. Children with autism also showed higher amplitude discrimination and temporal order judgement thresholds compared to neurotypical children. Tactile perceptual metrics did not associate with social or tactile sensitivities measured by parent-reports. Altered tactile behavioral responses appear in early childhood, can be quantified but appear dissociated from sensitivity. This implies these measures are complementary, but not necessarily related, phenomena of atypical tactile perception in autism.

Limbic brain subregions associated with mental health symptoms in youth with and without prenatal alcohol exposure.

BACKGROUND: Prenatal alcohol exposure (PAE) can result in reduced brain volume and an increased risk of mental health challenges. Limbic brain structures such as the hippocampus, thalamus, and amygdala often exhibit smaller volumes in youth with PAE, and similar volume reductions are observed in unexposed youth with symptoms of depression, bipolar disorder, anxiety, and schizophrenia. However, the role of volume reductions in these brain regions in mental health challenges remains unclear for individuals with PAE. METHODS: Thirty-four youth with PAE and 72 unexposed youth aged 7-16 years completed a T1-weighted magnetic resonance imaging scan. FreeSurfer was used to process and extract volumes for hippocampal subfields, thalamic subnuclei, and amygdalar subnuclei. Depression and anxiety symptoms were measured using the Behavioral Assessment System for Children (BASC-2/3-PRS), the Children's Depression Inventory, and the Multidimensional Anxiety Scale for Children. We tested whether limbic subregion volumes differed between youth with and those without PAE and whether volumes were associated with depression and/or anxiety symptoms, controlling for age and gender. RESULTS: Multiple hippocampal and thalamic subregions, but not amygdalar subnuclei, were smaller in individuals with PAE. Multiple group-brain interactions were observed for depression symptoms and subregion volumes. Negative associations between anxiety and limbic subregions were observed across groups. CONCLUSIONS: These findings show extensive volume reductions in the hippocampus and thalamus in youth with PAE. PAE also appears to disrupt the association between depression symptoms and limbic subregions in youth, which may have implications for interventions in these individuals. Anxiety symptoms in youth with and without PAE are similarly associated with limbic volumes.

Caregivers' experiences and perceptions of suicidality among their children and youth with fetal alcohol spectrum disorder.

Individuals with Fetal Alcohol Spectrum Disorder (FASD) experience a range of biopsychosocial vulnerabilities that can increase the possibility of adverse life outcomes, including a heightened risk of suicidality. In this study, we explored the lived experiences of caregivers of children and youth with FASD and suicidality, including their perceptions of their child and youth's suicidal experiences. Between March and June 2021, six comprehensive, semi-structured interviews were conducted with five caregivers of children and youth with FASD (Mage = 14.5 years, range 11-22) who were currently experiencing suicidality or had a history of suicidality. Data were analyzed using interpretative phenomenological analysis and then developed into a composite vignette informed and organized by the social-ecological suicide prevention model (SESPM). The composite vignette revealed the narratives of families living with and caring for children and youth with FASD who experience suicidality in relation to the complex and intersectional individual, relational, community, and societal level contextual and protective factors. Findings from this study highlight the critical need for comprehensive FASD-informed suicide prevention and intervention approaches to promote the mental health and wellbeing of children and youth with FASD and their caregivers.

Brain volume and magnetic susceptibility differences in children and adolescents with prenatal alcohol exposure.

BACKGROUND: Prenatal alcohol exposure (PAE) can negatively affect brain development thereby increasing the risk of cognitive deficits, behavioral challenges, and mental health problems. Brain iron is important for a number of physiological processes for healthy brain development. Animal studies show that PAE reduced brain iron; however, this has not been investigated in human children with PAE. METHODS: We studied 20 children and adolescents with PAE and 44 unexposed children and adolescents aged 7.5 to 15 years. All children underwent quantitative susceptibility mapping and T1-weighted magnetic resonance imaging scans. Susceptibility and volume measurements of the caudate, putamen, pallidum, thalamus, amygdala, hippocampus, and nucleus accumbens were extracted using FreeSurfer. ANCOVAs were used to compare volume and susceptibility between groups for each region of interest, controlling for age and gender. For structures where susceptibility differed by group, we also tested for an association between intelligence quotient (IQ) and susceptibility. RESULTS: There were no significant group differences in susceptibility after multiple comparison correction, though the PAE group had higher susceptibility in the thalamus compared to unexposed participants before correction (p = 0.032, q = 0.230). There was no association between IQ and thalamus susceptibility. The PAE group had significantly lower volume in the bilateral caudate, bilateral pallidum, and left putamen. CONCLUSIONS: These findings suggest susceptibility may be altered in children and adolescents with PAE, though more research is needed. Volume reductions are consistent with previous literature and likely underlie cognitive and behavioral deficits associated with PAE.
