ABSTRACT
Mother-infant interactions are co-regulated and provide the foundation for mother-infant relationship quality. The implications of maternal depression and contextual demands (i.e., reinstating the interaction following maternal unavailability and vocalized infant distress) on observationally coded co-regulation in mother-infant dyads (n = 40) at 4-months was investigated. Associations among co-regulation patterns and mother-infant relationship quality was also examined. Dyads participated in Still-Face (SF) and Separation (SP) procedures, with periods of maternal emotional and physical unavailability. Co-regulation was captured using the Revised Relational Coding System. Relationship quality was examined using the Emotional Availability Scales. Dyads in the depressed group had significantly more unilateral exchanges than the non-depressed group following the SF and SP perturbations. The depressed group also had significantly more distress vocalizations during the SP perturbation than the non-depressed group. Co-regulation in the depressed group was less disrupted by the SF perturbation. Positive relationship quality dimensions (maternal sensitivity, structuring, and infant responsiveness) were associated with more symmetrical and less unilateral co-regulation regardless of the interaction period. There were also context-specific results pertaining to patterns of co-regulation and associated maternal hostility and infant responsiveness. Results highlight co-regulatory differences in depressed mothers and their infants and how these differences are exacerbated by contextual demands.
ABSTRACT
OBJECTIVES: This systematic review and meta-analysis aims to describe Canadian youth mental health during the COVID-19 pandemic, focusing on changes in anxiety and depressive symptoms and suicidality. METHODS: We searched four databases up to February 2023 for longitudinal or repeated cross-sectional studies reporting on changes in depressive and anxiety symptoms, suicidality, or related services utilization among young people under 25 years old residing in Canada during the COVID-19 pandemic. Random-effects meta-analyses were performed for studies comparing depressive and anxiety symptoms from before to during the first, second, and third COVID-19 waves (up to June 2021), and between COVID-19 waves. Other studies were described narratively. Risk of bias was assessed using an adapted Joanna Briggs Institute Checklist. SYNTHESIS: Of the 7916 records screened, 35 articles met inclusion criteria for this review. Included studies were highly heterogeneous in design, population, and type of change investigated, and many had a high risk of bias. The meta-analyses found that depressive symptoms worsened minimally from pre-pandemic to wave 1 but returned to pre-pandemic levels by wave 2. Anxiety symptoms were broadly comparable from pre-pandemic to waves 1 and 2 but worsened from waves 1 to 3 and from pre-pandemic to wave 1 for girls. The narrative review included several studies that provided inconclusive evidence of increases in services utilization. CONCLUSION: The current evidence is limited and highly heterogeneous, making it insufficient to draw definitive conclusions regarding the short- to medium-term impact of the pandemic on youth mental health in Canada. Obtaining better mental health surveillance among Canadian youth is imperative.
RéSUMé: OBJECTIFS: Cette revue systématique et méta-analyse vise à décrire la santé mentale des jeunes Canadiens pendant la pandémie de COVID-19 en ce qui concerne les changements dans les symptômes d'anxiété et de dépression et la suicidalité. MéTHODES: Nous avons cherché dans quatre bases de données, jusqu'en février 2023, des études longitudinales ou transversales répétées portant sur l'évolution des symptômes dépressifs et anxieux, de la suicidalité ou de l'utilisation des services en santé mentale chez les jeunes de moins de 25 ans résidant au Canada pendant la pandémie de COVID-19. Des méta-analyses à effets aléatoires ont été réalisées pour les études comparant les symptômes dépressifs et anxieux avant et pendant les première, deuxième et troisième vagues du COVID-19 (jusqu'en juin 2021), ainsi qu'entre les vagues de COVID-19. Les autres études ont été décrites de manière narrative. Le risque de biais a été évalué à l'aide d'une liste de contrôle adaptée du Joanna Briggs Institute. SYNTHèSE: Sur les 7 916 dossiers examinés, 35 articles répondaient aux critères d'inclusion de la présente étude. Les études retenues sont très hétérogènes en termes de conception, de population et de type de changement étudié, et un grand nombre d'entre elles présentent un risque élevé de biais. Les méta-analyses révèlent que les symptômes dépressifs se sont légèrement aggravés entre la période prépandémique et la première vague, mais qu'ils sont revenus aux niveaux prépandémiques lors de la deuxième vague. Les symptômes d'anxiété sont globalement comparables entre la période prépandémique et les vagues 1 et 2, mais se sont aggravés entre les vagues 1 et 3 et entre la période prépandémique et la vague 1 pour les filles. La revue narrative porte sur plusieurs études qui ont fourni des preuves non concluantes de l'augmentation de l'utilisation des services en santé mentale. CONCLUSION: Les données actuelles sont limitées et très hétérogènes, ce qui ne permet pas de tirer des conclusions définitives quant à l'impact à court et moyen terme de la pandémie sur la santé mentale des jeunes au Canada. Il est impératif d'améliorer la surveillance de la santé mentale des jeunes Canadiens.

PURPOSE: There is a growing interest in assessing the benefits of exposure to urban greenspace on mental health due to the increased urbanization of youth and concerns for their mental health. We investigated the prospective associations of residential greenspace in childhood and mental health in adolescence. Use of a well-characterized birth cohort permitted adjustment for a range of potential confounding factors including family and neighborhood characteristics in addition to prior mental health problems, and exploration of moderation effects by sex and family socioeconomic status. METHODS: We analyzed longitudinal data collected from 742 urban-dwelling participants of the Quebec Longitudinal Study of Children Development. The Normalized Difference Vegetation Index (NDVI) within 250, 500, and 1000 m buffer zones surrounding the home residence was used to indicate childhood exposure to greenspace. Six self-reported mental health problems at 15/17 years were examined using the Mental Health and Social Inadaptation questionnaire: inattention, hyperactivity/impulsivity, conduct, depression, anxiety, and suicidal ideation. RESULTS: Childhood urban greenspace was associated with lower inattention problems in both females and males. We observed a 0.14 reduced standard deviation (SD) (ß = - 0.14, SE = 0.05, p < 0.01) in relation to an interquartile range (IQR) increase of NDVI (0.15) at the 250 m buffer zone, and similar results were found in 500 m and 1000 m buffer zones. These associations only slightly attenuated after adjustment for individual (sex, childhood mental health), family (family SES, maternal age at birth, parental mental health, family composition), and neighborhood (material and social deprivation) characteristics (ß = - 0.13, SE = 0.06, p = 0.03). No association was found for other mental health problems, and no moderation associations of sex or family socioeconomic status were observed. CONCLUSION: These findings suggest that increasing residential greenspace in cities may be associated with modest benefits in attentional capacities in youth, necessitating further research to elucidate the underlying mechanisms.
ABSTRACT
OBJECTIVE: To investigate prospective associations between type of child abuse (physical, sexual, both), timing (childhood, young adulthood, both), and welfare receipt into middle-age. METHODS: Database linkage study using the Quebec Longitudinal Study of Kindergarten Children cohort born in 1980 and government administrative databases (N = 3020). We assessed parental tax returns, family and personal background characteristics (1982-1987). At age 22 years, participants answered retrospective questionnaires on experienced childhood abuse (physical, sexual abuse < age 18 years) and intimate partner violence (IPV) (ages 18-22). Main outcome was years on social assistance, on the basis of participant tax returns (ages 23-37 years). Analysis included weights for population representativeness. RESULTS: Of 1690 participants (54.4% females) with available data, 22.4% reported childhood abuse only, 14.5% IPV only, and 18.5% both. Prevalence of childhood physical, sexual, and both was 20.4%, 12.2%, and 8.3%, respectively. Adjusting for socioeconomic background and individual characteristics, we found that childhood physical abuse alone and physical or sexual abuse combined were associated with a two-fold risk of welfare receipt, as compared to never-abused (adjusted incidence risk ratio 2.43, 95% confidence interval [CI], 1.65-3.58; and adjusted incidence risk ratio 2.04, 95% CI, 1.29-3.23, respectively). Repeated abuse (childhood abuse combined with adult IPV) had a three-fold risk (adjusted incidence ratio 3.59, 95% CI, 2.39-5.37). CONCLUSIONS: Abuse across several developmental periods (childhood and young adulthood) is associated with increased risks of long-term welfare receipt, independently of socioeconomic background. Results indicate a dose-response association. Early prevention and targeted identification are crucial to preventing economic adversity that may potentially lead to intergenerational poverty.

INTRODUCTION: Child sexual abuse remains a worldwide concern with devastating consequences on an individual's life. This longitudinal study investigates the associations between child sexual abuse (official reports versus retrospective self-reports) and subgroups by perpetrator identity (intrafamilial and extrafamilial), severity (penetration/attempted penetration, fondling/touching, noncontact), and chronicity (single, multiple episodes) and employment earnings in adulthood in a cohort followed for over 30 years. METHODS: The Quebec Longitudinal Study of Kindergarten Children database was linked to child protection services (official reports of sexual abuse) and to Canadian government tax returns (earned income). The sample included 3,020 individuals in Quebec French-language school kindergartens in 1986/1988, followed until 2017, and assessed with retrospective self-reports at age 22 years. Tobit regressions were used for associations with earnings (ages 33-37 years), adjusting for sex and family socioeconomic characteristics in 2021-2022. RESULTS: Individuals who experienced child sexual abuse had lower annual earnings. Those with retrospective self-reported sexual abuse (n=340) earned $4,031 (95% CI= -7,134, -931) less annually at ages 33-37 years than nonabused individuals (n=1,320), with pronounced differences for those with official reports (n=20), earning $16,042 (95% CI= -27,465, -4,618) less. Individuals self-reporting intrafamilial sexual abuse earned $4,696 (95% CI= -9,316, -75) less than those who experienced extrafamilial sexual abuse, whereas those self-reporting penetration/attempted penetration earned $6,188 (95% CI= -12,248, -129) less than those who experienced noncontact sexual abuse. CONCLUSIONS: Earnings gaps were highest for severest child sexual abuse (official reports, intrafamilial, penetrative). Future studies should investigate the underlying mechanisms. Improving support for victims of child sexual abuse could yield socioeconomic returns.

BACKGROUND: Suicide in children is a pressing public health concern. The increasing number of deaths by suicide and emergency visits for suicidal ideation and self-harm in children might not be fully representative; it is likely that many more children are in distress but do not seek out help. We conducted a systematic review and meta-analysis of existing studies to quantify the prevalence of suicidal ideation and self-harm behaviours among children in the community aged 12 years and younger. METHODS: In this systematic review and meta-analysis, we searched PsycINFO, MEDLINE, and Web of Science via OVID from database inception to Feb 28, 2022, for articles published in French or English that reported estimates of prevalence of suicidal ideation (including suicide planning) and self-harm behaviours (namely, self-harm, suicide attempts, and non-suicidal self-injury) in children aged 12 years and younger. Reference lists were also searched; case studies, qualitative studies, and health-care visit studies were excluded. The outcomes were suicidal ideation, suicide plan or attempts, and self-harm. We used a random-effects model to calculate the overall pooled prevalence of suicidal ideation and self-harm behaviours for all timeframes combined and for ever versus the past 12 months for suicidal ideation. We used the Joanna Briggs Institute Critical Appraisal tool to evaluate the risk of bias in each study. This study is registered with PROSPERO, CRD42020179041. FINDINGS: 28 articles, encompassing 30 studies overall, met the inclusion criteria, aggregating findings from 98 044 children (of whom 46 980 [50·5%] were girls and 46 136 [49·5%] were boys; six articles did not report sex or gender) aged 6-12 years. The pooled prevalence estimate was 7·5% (95% CI 5·9-9·6) for suicidal ideation from 28 studies and 2·2% (2·0-2·5) for suicide planning from three studies. The pooled prevalence was 1·4% (0·4-4·7) for self-harm from four studies, 1·3% (1·0-1·9) for suicide attempt from six studies, and 21·9% (6·2-54·5) for non-suicidal self-injury from two studies. The prevalence of suicidal ideation was higher in studies that included child-reported outcomes (10·9% [95% CI 8·1-14·5] for child only and 10·4% [6·8-15·5] for child and parent combined) than for parent-only reported outcomes (4·7% [3·4-6·6]; p=0·0004). The prevalence of suicidal ideation and self-harm behaviours was similar in boys and girls (suicidal ideation, 7·9% [95% CI 5·2-12·0] for boys vs 6·4% [3·7-10·7] for girls; self-harm behaviours, 3·5% [1·6-7·2] for boys vs 3·0% [1·4-6·4%] for girls). Detailed ethnicity data were not available. High heterogeneity was identified across estimates (I2>90%), which was not well explained by the characteristics of the studies. INTERPRETATION: A high number of children in the general population can experience suicidal ideation and self-harm behaviours, thus underlining the need for more research on childhood suicide, including developmentally appropriate preventive strategies, such as youth-nominated support teams or dialectical behavioural therapy.

From birth, mothers and infants co-regulate their interactions that are shaped by their socio-emotional development, relationship history, current circumstances, and goals. However, few studies have longitudinally explored co-regulation in the context of medical and psycho-social risk. The present 4-wave longitudinal study sought to shed light on factors associated with co-regulation over time in infants from 6- to 48-months. The objectives were to 1) identify differences in co-regulation among low- and at-risk infant-mother dyads, 2) explore changes in co-regulation over time, and 3) explore the associations between infant-mother co-regulation and parenting stress in these low- and at-risk groups over time. Participants included three groups of infant-mother dyads (full-term [FT], n = 48; very low birthweight/preterm [VLBW/preterm] born 26-32 weeks, weighing 800-1500 g, n = 61; psycho-socially at-risk where parents had histories of socioeconomic disadvantage, n = 54) followed longitudinally at 6-, 12-, 18-, and 48-months of age. Dyads engaged in a free play in their homes that was coded for co-regulation using Fogel, de Koeyer, Secrist, Sipherd, Hafen, and Fricke's (2003) Revised Relational Coding System (RRCS), and mothers reported on their level of parenting stress. Results from MANOVAs at each time point indicated significant differences between the groups at 18-months, with psycho-socially at-risk dyads engaging in more one-sided interactions than FT and VLBW/preterm dyads, and more dysregulation and miscommunication than VLBW/preterm dyads. Multi-level models of co-regulation revealed that dyads became progressively less synchronous from 6- to 12-months, followed by greater synchrony and mutual reciprocity from 12-months onwards. Parenting stress was associated with less synchrony and less mutual reciprocity amongst the at-risk groups. Maternal education was associated with greater engagement and girls tended to engage in more synchronous interactions than boys. Our results underscore the value and implications of considering background risk and concurrent parent perceptions in the development and reciprocity of parent-infant co-regulation and their subsequent relationships from infancy onwards.

BACKGROUND: Youth who attempt suicide are more at risk for later mental disorders and suicide. However, little is known about their long-term socioeconomic outcomes. AIMS: We investigated associations between youth suicide attempts and adult economic and social outcomes. METHOD: Participants were drawn from the Quebec Longitudinal Study of Kindergarten Children (n = 2140) and followed up from ages 6 to 37 years. Lifetime suicide attempt was assessed at 15 and 22 years. Economic (employment earnings, retirement savings, welfare support, bankruptcy) and social (romantic partnership, separation/divorce, number of children) outcomes were assessed through data linkage with government tax return records obtained from age 22 to 37 years (2002-2017). Generalised linear models were used to test the association between youth suicide attempt and outcomes adjusting for background characteristics, parental mental disorders and suicide, and youth concurrent mental disorders. RESULTS: By age 22, 210 youths (9.8%) had attempted suicide. In fully adjusted models, youth who attempted suicide had lower annual earnings (average last 5 years, US$ -4134, 95% CI -7950 to -317), retirement savings (average last 5 years, US$ -1387, 95% CI -2982 to 209), greater risk of receiving welfare support (risk ratio (RR) = 2.05, 95% CI 1.39 to 3.04) and were less likely to be married/cohabiting (RR = 0.82, 95% CI 0.73 to 0.93), compared with those who did not attempt suicide. Over a 40-year working career, the loss of individual earnings attributable to suicide attempts was estimated at US$98 384. CONCLUSIONS: Youth who attempt suicide are at risk of poor adult socioeconomic outcomes. Findings underscore the importance of psychosocial interventions for young people who have attempted suicide to prevent long-term social and economic disadvantage.
