The association between depressive symptoms and overweight or obesity in prepubertal children: Findings from the QUALITY cohort

BACKGROUND

Youth obesity and depression are public health concerns. Although meta-analyses suggest a positive association between those conditions in adults and adolescents, evidence remains unclear in prepubertal children. We examined the bidirectional associations between levels of depressive symptoms and weight status in 8-10-year-old children with a parental history of obesity, over two years, and whether they differ by sex.

METHODS

Data were drawn from the QUebec Adipose and Lifestyle InvesTigation in Youth Cohort Study's baseline and first follow-up evaluations (n = 558). Depressive symptoms were assessed using the 12-item Center for Epidemiological Studies Depression scale and weight status using body mass index z-scores based on World Health Organization standards. Linear and logistic regression models were used to test the directionality and magnitude of the associations, adjusting for age, sex, physical activity, screen time, parental education, alcohol and cigarette use, and baseline outcome measure.

RESULTS

Children with higher levels of depressive symptoms at baseline were not more likely to have overweight/obesity at follow-up (odds ratio [95 % Coefficient Interval] = 0.95[0.88;1.02]). Baseline overweight/obesity was not associated with subsequent higher levels of depressive symptoms (beta coefficient [95 % Coefficient Interval] = 0.20 [-0.47;0.87]). No sex differences emerged.

LIMITATIONS

Selection bias may have occurred due to loss at follow-up (10 % attrition) and exclusion of 6 participants taking mood disorder medication.

CONCLUSIONS

Unlike in adults and adolescents, no association between weight status and depressive symptoms was observed in childhood over two years. Underlying mechanisms linking both conditions later in life may not apply as early as prepubertal childhood.

Origins and developmental paths of medical conditions from mid-childhood to mid-adolescence in Australia: Early-life adverse conditions and their lasting effects

This study investigates various common medical conditions affecting Australian children aged 4-14 years and the impact of prenatal and early-life conditions on these health conditions using a large national data set (n = 4122) with 15 years of follow-up. Consistent with the developmental origins of health and diseases hypothesis and the life-course models of health, the in-utero environment and parental financial hardship during pregnancy and shortly after birth play a significant role and have a lasting impact on the medical conditions of children. These significant effects are not reduced by controlling for child, family, and neighbourhood characteristics. The impact of improvements in family income when the child is aged 4-14 years does not compensate for the impact of health disadvantages in the prenatal and postnatal period.

What role does the environment play in language development? Exploring the associations among socioeconomic status, parent language input, and language skills in school-aged children with autism

Language development in children with autism is influenced by proximal (e.g., parent language input) and distal (e.g., socioeconomic status) environmental constructs. Studies have found that "rich and responsive" parent language input supports autistic children's language development, and recent work has reported positive associations between measures of socioeconomic status (SES) and child language skills. However, little is known about how these proximal and distal environmental constructs interact to shape language development in autism. In a sample of 74 autistic school-aged children, the present study investigated the associations among measures of SES, the quantity and quality of language produced by parents and children during home-based dyadic parent-child interactions, and children's expressive and receptive language skills. Results showed that annual household income was positively associated with parent number of total words (NTW), parent number of different words (NDW), and parent mean length of utterance (MLU), while neither parent education level nor annual household income were significantly associated with measures of child language skills. Parent MLU was positively associated with child MLU and child expressive language skills. Findings suggest that annual household income may influence both the quantity and quality of parent language input, and that parent MLU, a qualitative measure of parent language input, may play a particularly important role in shaping autistic children's expressive language development. Future research should study longitudinal associations among SES, parent language input, and child language skills, as identifying environmental predictors of language skills in autism may facilitate the creation of more effective interventions that support language development.

Living the first years in a pandemic: children's linguistic development and related factors in and out of the COVID-19 lockdowns

This retrospective study provides insights on linguistic development in exceptional circumstances assessing 378 children (between 2;6 and 3;6) who lived their first years during the COVID-19 pandemic and comparing it with normative data collected before this period (CDI-III-PT; Cadime et al., 2021). It investigates the extent to which linguistic development was modulated by a complex set of factors, including sex, maternal education, book reading, language-promoting practices, COVID-19 infection, parental stress and sleeping problems, considering three periods (during lockdowns, out of lockdowns and at present). The results show a substantial negative effect of the pandemic on both lexical and syntactic development. Considering individual variation, structural equation modelling unveiled a complex scenario in which age, sex, book reading, language-promoting practices, sleeping problems and COVID-19 infection showed a direct effect on linguistic development. Maternal education and parental stress had an indirect effect on children's language, mediated by book reading and sleeping problems, respectively.

Learning from those who thrive: protective factors and neuroimaging markers in adolescents with complex congenital heart disease and with a favorable neurodevelopmental profile

Patients with complex congenital heart disease (cCHD) are at risk for neurodevelopmental impairments, yet many patients develop normally. This study investigated associations between a favorable neurodevelopmental profile and protective factors, quality of life (QoL), resilience, and brain development. Adolescents with cCHD (n = 100) were prospectively enrolled. Neurodevelopmental profiles comprised IQ, executive functions, and behavior. Standardized neuropsychological tests and questionnaires were used to assess neurodevelopmental outcomes, family factors, QoL, and resilience. Clinical data were obtained from medical charts. Cerebral MRI was acquired. Specific neurodevelopmental profiles were identified by latent profile analysis and were associated with clinical and family factors, QoL and resilience, and MRI markers. We identified two distinct groups of neurodevelopmental profiles (favorable profile: n = 57, vulnerable profile: n = 43). The favorable profile group had significantly better neurodevelopmental outcome, better family functioning, and better parental mental health compared to the vulnerable profile group. Clinical factors were not significantly associated with profile group. The favorable profile group reported significantly better QoL and resilience and had larger total brain volumes. A positive family environment may be protective for long-term neurodevelopment and may outweigh the role of clinical factors. This study underlines the importance of family-centered care to promote favorable brain development and neurodevelopmental outcome.

Longitudinal interactions between maternal depression symptoms and familial stressful life events on child anxiety symptoms at 5 years of age

In the current study we identified salient parental factors for child anxiety symptoms by considering the role of stressful life events, maternal anxiety symptoms, maternal depressive symptoms, and maternal neuroticism. Families (N = 399) in an urban area in the United States were participants in a longitudinal study beginning in infancy. Mothers completed measures of stressful life events (Revised Life Events Questionnaire at all visits), maternal anxiety and depressive symptoms (State-Trait Anxiety Inventory and Beck Depression Inventory, respectively, at infancy between 5 and 12 months, at 2 years, and at 3 years), maternal neuroticism (NEO Five-Factor Inventory at infancy), and child anxiety symptoms (Child Behavior Checklist 1.5-5 at 5 years). Linear mixed models (LMMs) were used in analyses. Maternal depressive symptoms from infancy through 3 years were associated with child anxiety symptoms; other main effects modeled (stressful life events, maternal anxiety symptoms, maternal neuroticism) were not associated with child anxiety symptoms. There was a significant interaction effect between stressful life events and maternal depression. Stressful events from infancy through 5 years of age increased risk for child anxiety symptoms at 5 years if the child's mother had a mild mood disturbance or depression, but not for children with non-depressed mothers.

The Influence of Temperament, Theory of Mind, Inhibitory Control, and Prosocial Behavior on Child Anxiety Symptoms in the First Five Years of Life

Anxiety disorders are among the most prevalent of all mental health disorders, often originating in early childhood and extending into later childhood, adolescence, and adulthood. Determining salient risk factors that precede their development is important for prevention and intervention efforts. Towards this end, we examined the role of temperament, theory of mind, inhibitory control, and prosocial behavior on child anxiety symptoms in the first 5 years of life. A community sample of children and their parents (N = 399) enrolled in a longitudinal study of emotion processing were assessed when the children were infants and at ages 2 years, 3 years, and 5 years. Linear mixed models and linear regression models revealed that greater anxiety at 5 years was associated with greater negative affectivity and behavioral inhibition, lower effortful control, lower theory of mind scores on the "desires" domain, and higher scores on the "intentions" domain (assessed from infancy to 3 years of age). These characteristics may be useful to assess in clinical settings to evaluate a patient's risk for developing anxiety. They may also be useful in developing interventions targeting specific vulnerabilities.

Could a Growth Mindset Attenuate the Link Between Family Socioeconomic Status and Depressive Symptoms? Evidence from Chinese Adolescents

Purpose

The alleviating effects of a growth mindset on depression are promising. However, whether a growth mindset can attenuate the effect of low family socioeconomic status (SES) on depressive symptoms among adolescents remains unknown. Based on the Family Stress Model, the current study explores whether a growth mindset could moderate the associations between family SES, interparental conflict, and adolescent depressive symptoms.

Methods

The participants were 1572 Chinese adolescents (Mage = 13.35 years, SD = 1.16, 51.84% female). They completed the family SES questionnaire, Children's Perceptions of Interparental Conflict scale, Growth Mindset scale, and Center for Epidemiologic Studies Depression scale. We tested the moderation, mediation, and moderated mediation models using the SPSS macro program PROCESS.

Results

A growth mindset moderated the association between family SES and depressive symptoms. Family SES was significantly related to depressive symptoms in adolescents with a lower growth mindset, but not in those with a higher growth mindset. After incorporating the mediating effect of interparental conflict, the growth mindset did not exert a significant moderating influence on the direct path; however, it significantly moderated the mediating effect of interparental conflict on depressive symptoms. Specifically, while a lower growth mindset in adolescents was associated with an increased risk of depressive symptoms due to interparental conflict, those with a higher growth mindset showed a less pronounced effect.

Conclusion

A growth mindset attenuates the link between family SES and depressive symptoms among adolescents. These findings highlight the benefits of a growth mindset on mental health, especially for low-SES adolescents.

The interplay of maternal and paternal postpartum depressive symptoms with children's internalizing and externalizing symptoms from childhood to adolescence: does socioeconomic status matter? A longitudinal cohort study

BACKGROUND

Maternal postpartum depression is an important risk factor for internalizing and externalizing problems in children. The role of concurrent paternal depression remains unclear, especially by socioeconomic status. This study examined independent and interactive associations of postpartum maternal and paternal depression with children's internalizing/externalizing symptoms throughout childhood and adolescence (ages 3.5-17 years).

METHODS

We used data from the Québec Longitudinal Study of Child Development, a representative birth cohort (1997-1998) in Canada. Data included self-reported maternal and paternal depressive symptoms at 5 months' postpartum using the Center for Epidemiologic Studies Depression Scale. Internalizing and externalizing symptoms in children were reported by parents, teachers and children/adolescents using the Social Behaviour Questionnaire (ages 3.5-13 years) and the Mental Health and Social Inadaptation Assessment for Adolescents (ages 15-17 years). We used three-level mixed effects modelling to test associations after adjusting for confounding factors.

RESULTS

With 168 single-parent families excluded, our sample consisted of 1,700 families with useable data. Of these, 275 (16.2%) families reported maternal depression (clinically elevated symptoms), 135 (7.9%) paternal depression and 39 (2.3%) both. In families with high socioeconomic status, maternal depression was associated with greater child internalizing (β = .34; p < .001) and externalizing symptoms (β = .22; p = .002), regardless of the presence/absence of paternal depression. In families with low socioeconomic status, associations with symptoms were stronger with concurrent paternal depression (internalizing, β = .84, p < .001; externalizing, β = .71, p = .003) than without (internalizing, β = .30, p < .001; externalizing, β = .24, p = .002).

CONCLUSIONS

Maternal depression increases the risk for children's internalizing/externalizing problems in all socioeconomic contexts. In families with low socioeconomic status, risks were exacerbated by concurrent paternal depression. Postpartum depression, especially in low socioeconomic environments, should be a primary focus to optimize mental health across generations.

Associations between parental socioeconomic status and mental health in Chinese children: the mediating roles of parenting practices

BACKGROUND

The significance of socioeconomic status (SES) in child mental health is well-established in Western populations; however, there is little evidence on this topic in Chinese populations. The possibility that Chinese families with different SES elicit different parenting practices that cause positive or negative child mental health outcomes warrants further investigation.

METHODS

This study examined the associations of SES, parenting practices, and child mental health among 1401 Chinese school children and their parents residing in Shanghai. SES was measured by a composed index of parental education levels, occupations, and household incomes. The Alabama parenting questionnaire (APQ; child version) and the strengths and difficulties questionnaire (SDQ; parent version) were used to assess parenting practices and child mental health. We also explored the underlying mechanisms between parental SES and the mental health of children by testing different parenting practices as mediators of the relationships.

RESULTS

The results showed that a higher SES is positively associated with better mental health in children. Positive involvement and deficient monitoring can mediate the relationship between SES and child mental health outcomes. Negative discipline did not significantly mediate the above relationship.

CONCLUSIONS

The results highlight the significance of positive involvement and sufficient monitoring in promoting children's mental health and provide evidence for designing effective programs to improve parenting skills.

The impact of poverty and socioeconomic status on brain, behaviour, and development: a unified framework

In this article, we, for the first time, provide a comprehensive overview and unified framework of the impact of poverty and low socioeconomic status (SES) on the brain and behaviour. While there are many studies on the impact of low SES on the brain (including cortex, hippocampus, amygdala, and even neurotransmitters) and behaviours (including educational attainment, language development, development of psychopathological disorders), prior studies did not integrate behavioural, educational, and neural findings in one framework. Here, we argue that the impact of poverty and low SES on the brain and behaviour are interrelated. Specifically, based on prior studies, due to a lack of resources, poverty and low SES are associated with poor nutrition, high levels of stress in caregivers and their children, and exposure to socio-environmental hazards. These psychological and physical injuries impact the normal development of several brain areas and neurotransmitters. Impaired functioning of the amygdala can lead to the development of psychopathological disorders, while impaired hippocampus and cortex functions are associated with a delay in learning and language development as well as poor academic performance. This in turn perpetuates poverty in children, leading to a vicious cycle of poverty and psychological/physical impairments. In addition to providing economic aid to economically disadvantaged families, interventions should aim to tackle neural abnormalities caused by poverty and low SES in early childhood. Importantly, acknowledging brain abnormalities due to poverty in early childhood can help increase economic equity. In the current study, we provide a comprehensive list of future studies to help understand the impact of poverty on the brain.

Exploring the Association between Parental Employment Status, Education Level, and Sensory Reactivity in Spanish Children Aged 3-7 Years: Findings from the InProS Study

This study explored the association between parental employment status and education level and the prevalence of sensory reactivity (SR) in population-based sample of school-aged children. SR was assessed in 495 children using the parent-reported Short Sensory Profile (SSP) questionnaire. Children with SR were identified based on probable or definitive differences in total SSP and subscales. Association between parental employment and education level were explored using multiple Poisson regression models with robust variance, adjusted for potential confounders. The main findings showed that a mother's unemployment status was associated with higher prevalence of SR for the taste/smell sensitivity subscale (PR = 1.66, 95%CI: 1.08-2.56), and the low energy/weak (PR = 2.18, 95%CI: 1.31-3.49) subscale. A lower education level of a father was also associated with a higher prevalence of sensory problems on the tactile sensitivity subscale (PRprimary education = 2.68, 95%CI: 1.27-5.61; PRsecondary education = 1.96, 95%CI: 1.004-3.66) and the low energy/weak subscale (PRsecondary education = 1.95, 95%CI: 1.02-3.73). This study underscores the impact of parental employment and education on SR in school-aged children, offering insights for interventions and support systems aimed at improving their sensory functioning and overall well-being.

Social Communication Delay in an Unbiased Sample of Preschoolers With the FMR1 Premutation

PURPOSE

The Fragile X Messenger Ribonucleoprotein-1 (FMR1) premutation (FXpm) is a genetic variant that is common in the general population and is associated with health symptoms and disease in adulthood. However, poor understanding of the clinical phenotype during childhood has hindered the development of clinical practice guidelines for screening and intervention. Given that social communication difficulties have been widely documented in adults with the FXpm and are linked with reduced psychosocial functioning, the present study aimed to characterize the communication profile of the FXpm during early childhood.

METHOD

Eighteen children with the FXpm who were identified through cascade testing (89%) or screening at birth (11%) were compared to 21 matched typically developing children, aged 2-4 years. Participants completed standardized assessments of language (Mullen Scales of Early Learning) and adaptive communication (Vineland Adaptive Behavior Scales-II). Social communication was rated from seminaturalistic interaction samples using the Brief Observation of Social Communication Change.

RESULTS

Children with the FXpm showed delayed social communication development, with the magnitude of group differences highlighting social communication as a feature that distinguishes children with the FXpm from their peers (p = .046, ηp2 = .12). The groups did not differ on the standardized language and adaptive communication measures (ps > .297, ηp2s < .03).

CONCLUSIONS

Early screening and treatment of social communication delays may be key to optimizing outcomes for children with the FXpm. Further research is needed to replicate findings in a larger sample, delineate the trajectory and consequences of social communication difficulties across the life span in the FXpm, and determine the potential epidemiological significance of FMR1 as a mediator of developmental communication differences within the general population.

Lower Childhood Socioeconomic Status Is Associated with Greater Neural Responses to Ambient Auditory Changes in Adulthood

Humans' early life experience varies by socioeconomic status (SES), raising the question of how this difference is reflected in the adult brain. An important aspect of brain function is the ability to detect salient ambient changes while focusing on a task. Here, we ask whether subjective social status during childhood is reflected by the way young adults' brain detecting changes in irrelevant information. In two studies (total n = 58), we examine electrical brain responses in the frontocentral region to a series of auditory tones, consisting of standard stimuli (80%) and deviant stimuli (20%) interspersed randomly, while participants were engaged in various visual tasks. Both studies showed stronger automatic change detection indexed by MMN in lower SES individuals, regardless of the unattended sound's feature, attended emotional content, or study type. Moreover, we observed a larger MMN in lower-SES participants, although they did not show differences in brain and behavior responses to the attended task. Lower-SES people also did not involuntarily orient more attention to sound changes (i.e., deviant stimuli), as indexed by the P3a. The study indicates that individuals with lower subjective social status may have an increased ability to automatically detect changes in their environment, which may suggest their adaptation to their childhood environments.

Socioeconomic Inequalities Affect Brain Responses of Infants Growing Up in Germany

Developmental changes in functional neural networks are sensitive to environmental influences. This EEG study investigated how infant brain responses relate to the social context that their families live in. Event-related potentials of 255 healthy, awake infants between six and fourteen months were measured during a passive auditory oddball paradigm. Infants were presented with 200 standard tones and 48 randomly distributed deviants. All infants are part of a longitudinal study focusing on families with socioeconomic and/or cultural challenges (Bremen Initiative to Foster Early Childhood Development; BRISE; Germany). As part of their familial socioeconomic status (SES), parental level of education and infant's migration background were assessed with questionnaires. For 30.6% of the infants both parents had a low level of education (≤10 years of schooling) and for 43.1% of the infants at least one parent was born abroad. The N2-P3a complex is associated with unintentional directing of attention to deviant stimuli and was analysed in frontocentral brain regions. Age was utilised as a control variable. Our results show that tone deviations in infants trigger an immature N2-P3a complex. Contrary to studies with older children or adults, the N2 amplitude was more positive for deviants than for standards. This may be related to an immature superposition of the N2 with the P3a. For infants whose parents had no high-school degree and were born abroad, this tendency was increased, indicating that facing multiple challenges as a young family impacts on the infant's early neural development. As such, attending to unexpected stimulus changes may be important for early learning processes. Variations of the infant N2-P3a complex may, thus, relate to early changes in attentional capacity and learning experiences due to familial challenges. This points towards the importance of early prevention programs.

Callous-Unemotional Traits and Co-occurring Anxiety in Preschool and School-age Children: Investigation of Associations with Family's Socioeconomic Status and Home Chaos

While contemporary literature has traditionally viewed youth with Callous-Unemotional (CU) traits as a homogeneous group, there is a growing interest in delineating two variants of CU traits based on high or low levels of anxiety. Extensive attention has been brought in the CU traits literature to the study of relational factors such as maltreatment and parenting practices. However, very few studies have looked at other environmental contexts in which the children within these two variants evolve, such as home chaos or socioeconomic status (SES). In a community sample of children aged 4 to 9, divided into a preschool sample (N = 107; Mage = 4.95, SD = 0.62) and a school-age sample (N = 153; Mage = 7.49, SD = 1.11), the current study investigated whether anxiety moderates the associations of CU traits with SES and home chaos. Hierarchical regression analyses revealed that CU traits were positively associated with home chaos, regardless of anxiety levels. CU traits were negatively associated with SES, but this effect emerged only at high levels of anxiety. Notably, these findings were observed solely in the school-age subsample. Implications for understanding the two variants of CU traits (i.e., primary and secondary) and hypotheses regarding their developmental trajectories are discussed.

Factors differentiating risk of sexual abuse victimization by adults and peers among adolescents

BACKGROUND

Research suggests that around half of all cases of sexual abuse among children and adolescents are perpetrated by peers. Yet, there is limited understanding of the distinct risk factors associated with adult versus peer offenders.

OBJECTIVE

To identify factors that increase the risk of sexual abuse victimization and explores variations in these factors depending on whether the perpetrator was an adult or a peer.

PARTICIPANTS AND SETTING

9240 secondary school students aged between 12 and 16 years (M = 14, SD = 0.88) in Norway participated.

METHODS

An electronic questionnaire was administered in schools to investigate experiences of sexual abuse and potential risk factors. The data were analyzed using multiple logistic regression analyses.

RESULTS

Two factors were related to a greater risk of being a victim of sexual abuse committed by an adult than a peer: background from a non-European country (OR = 1.93, p = 0.038) and other experiences of violence (OR = 1.63-2.91, p < 0.005). The use of alcohol was found to be related to a greater risk of victimization by peers than by adults (OR = 0.53, p = 0.031).

CONCLUSIONS

Adolescents vulnerable to sexual abuse exhibit common traits, regardless of whether the perpetrator is an adult or peer. Yet, specific factors heighten the risk with peers over adults, and vice versa. Recognizing distinct risk factors for abuse by adults and peers enables decision-makers and community workers to create targeted prevention strategies for children and adolescents.

Mental health among adolescents exposed to social inequality in Latin America and the Caribbean: a scoping review

Background and objective

Adolescents from Latin America and the Caribbean grow up in a context of social inequality, which diminishes their well-being and leads to impaired emotional-cognitive development. To understand the problem, it is important to synthesize the available research about it. This study aims to explore the knowledge about adolescents' mental health in Latin America and the Caribbean exposed to social inequality.

Methods

A systematic scoping review was conducted encompassing a search in five databases (Medline, CINAHL, PsycINFO, Scopus, and LILACS) in June 2022. Articles of various typologies were included without time limit. After two rounds of screening, relevant data were manually extracted and synthesized into self-constructed themes using thematic analysis.

Results

Out of 8,825 retrieved records, 42 papers were included in the final review, with a predominance of quantitative approaches. The synthesis revealed two main analytical themes: (a) defining social inequality, wherein intersecting inequalities produce discrimination and determine conditions for social vulnerability; (b) social inequality and mental health, which highlights the association between socio-structural difficulties and emotional problems, amplifying vulnerability to mental ill health and poor mental health care.

Conclusion

The scientific evidence reveals that social inequality is related to impaired well-being and mental ill health on the one hand and a lack of access to mental health care on the other hand.

The emoji current mood and experience scale: the development and initial validation of an ultra-brief, literacy independent measure of psychological health

BACKGROUND

There is increasing interest in measuring wellbeing and mental health in a range of settings and services outside conventional mental health care settings. However, ensuring that measurement does not intrude on the primary service activity whilst promoting inclusion through minimizing literacy demands, requires ultra-brief and easy to use tools.

AIMS

To develop and test a brief emoji-based tool to assess mental health, wellbeing, resilience and community connection.

METHOD

In study 1, 672 adults completed an online questionnaire study comprising a new emoji measure and established questionnaires assessing mental health, resilience, community connection and wellbeing. In study 2, 415 participants completed a paper-and-pencil version of the emoji measure, mental health and community connection, with 212 individuals providing data at a second time point.

RESULTS

Multidimensional scaling revealed a meaningful structure to the emoji measure with validity demonstrated through relationships to existing scales. Stability over time and sensitivity to change were also demonstrated.

CONCLUSIONS

The emoji-based measure presented here provides an ultra-brief measure of mood and current experience, with minimal literacy demands on participants. Further research is now needed to test the properties and utility of the scale with other participant groups.

If Opportunity Knocks: Understanding Contextual Factors' Influence on Cognitive Systems

Central to the Research Domain Criteria (RDoC) framework is the idea that RDoC constructs, which vary dimensionally by individual, are heavily influenced by contextual factors. Perhaps chief among these contextual factors is structural opportunity - the quality of resources available to a child as they grow. The aim of this study is to understand the impact of access to opportunity during childhood on three central RDoC cognitive systems constructs: language, visual perception, and attention. These constructs were measured using clinical data from psychological evaluations of youth ages 4-18 years (N = 16,523; Mage = 10.57, 62.3% male, 55.3% White). Structural opportunity was measured using the geocoded Child Opportunity Index 2.0 (COI), a composite score reflecting 29 weighted indicators of access to the types of neighborhood conditions that help children thrive. Findings indicate that, controlling for demographic and socioeconomic factors, greater access to opportunity is associated with significantly stronger cognitive skills across all three constructs. However, opportunity uniquely explains the largest proportion of the variance in language skills (8.4%), compared to 5.8% of the variance in visual processing skills and less than 2% of the variance in attention. Further, a moderating effect of age was found on the relation between COI and language skills, suggesting that the longer children remain exposed to lower levels of opportunity, the lower their language skills tend to be. Understanding how opportunity impacts cognitive development allows clinicians to offer better tailored recommendations to support children with cognitive systems deficits, and will support policy recommendations around access to opportunity.

Longitudinal associations between socioeconomic status and psychosocial problems in preschool children

Socioeconomic status (SES) at different points in a child's lifetime may have different effects on health outcomes. This study aimed to examine longitudinal associations between SES and psychosocial problems in preschool children (n = 2509, Mage = 24.2 ± 1.3 months). The psychosocial problems of children were assessed using the Brief Infant-Toddler Social and Emotional Assessment at age 2 years and age 3 years and categorized as having yes/no psychosocial problems. Four groups of pattern of presence/absence of psychosocial problems between age 2 and 3 years were classified: (1) 'no problems', (2) 'problems at age two', (3) 'problems at age three', and (4) 'continuing problems'. Five indicators of SES (i.e., maternal education level, single-parent family, unemployment, financial problems, and neighborhood SES) were evaluated. Results showed around one-fifth (2Y = 20.0%, 3Y = 16.0%) of children had psychosocial problems. Multinomial logistic regression models revealed low and middle maternal education levels were associated with 'problems at age two'; low maternal education level and financial problems were associated with 'problems at age three'; low and middle maternal education level, single-parent family, and unemployment were associated with 'continuing problems'. No associations were observed between neighborhood SES and any pattern. Results suggest children in a lower SES, indicated by maternal education, single-parent family, and financial stress, had higher odds of developing and continuously having psychosocial problems in early childhood. These findings call for optimally timing interventions to reduce the impact of disadvantaged SES in early childhood on psychosocial health.

Are the presence of asthma and the COVID-19 infection associated with behavioral changes in Lebanese adolescents?

BACKGROUND

Little evidence is available about psychological stressors in Lebanese asthmatic adolescents, where health-risk behaviors are a serious threat to public health. In addition, the COVID-19 epidemic has had a substantial influence on adolescents' mental health globally, especially in Lebanon, where the ongoing economic and political challenges have largely impacted their psychological well-being. This study aimed to explore the association of asthma and the COVID-19 infection with behaviors among Lebanese adolescents.

METHODS

Data were collected in July 2023, using the snowball sampling technique. Inclusion criteria for participation in the study included being of a resident and citizen of Lebanon and aged 12-18 years. Behavioral problems were assessed using the Youth Self-Report (YSR) scale, which yields nine subscales (anxious/depressed, withdrawn/depressed, somatic complaints, social problems, thought problems, attention problems, rule-breaking behavior, aggressive behavior, and other problems) and a total score.

RESULTS

Asthma was significantly associated with somatic complaints (Beta [β] = 2.98), attention problems (β = 0.01), and other behavioral problems (β = 0.68). Having contracted the COVID-19 infection, compared to healthy asymptomatic state (β = 1.55), was significantly associated with more anxious behaviors. In the case of stratifying the analysis in terms of gender, the results showed that the presence of asthma was significantly associated with more social behaviors (β = 3.31), thought problems (β = 2.91), attention problems (β = 0.02), other behavioral problems (β = 1.71), and total behavioral problems (β = 5.71) in males. In case stratifying the analysis as to school type, the presence of asthma was significantly associated with more somatic complaints (β = 2.77) in participants from private schools whereas it was significantly associated with more total behavioral problems (total YSR scores) (β = 5.05) in participants from public schools.

CONCLUSION

It is confirmed that asthma and psychiatric disorders are interconnected, so it would be of great importance to include screening through a psychological intervention in treating asthmatic adolescents by means of (1) recognizing factors affecting patients' mental health, and (2) regulating uncontrolled behaviors that can exacerbate symptoms in order to avoid the future morbidity.

Infant screen media and child development: A prospective community study

The current study examined longitudinal associations between early screen media exposure (assessed at 6, 12, and 24 months) and the child's motor and language/communication development at the ages of 24 and 36 months. We also aimed to study whether these associations varied by socioeconomic status (SES). Participants were 179 parent-infant dyads, recruited from well-baby clinic services during routine visits. Child development measures included standardized measures of developmental milestones as assessed by professionals and referral data to child developmental centers. Both measures were retrieved from the official health maintenance organization records by an expert in child development. Results indicated that screen exposure at 6 and 12 months was associated with a higher risk for language/communication deficits at 36 months in children with moderate or high SES but not in children with low SES. Our findings are consistent with existing literature demonstrating cross-sectional and longitudinal associations between early screen exposure and language development deficits. Given that media use practices and motivations vary among families from different backgrounds, further investigation of the interaction between SES and screen exposure is needed.

Parental education and income are linked to offspring cortical brain structure and psychopathology at 9-11 years

Background

A child's socioeconomic environment can shape central aspects of their life, including vulnerability to mental disorders. Negative environmental influences in youth may interfere with the extensive and dynamic brain development occurring at this time. Indeed, there are numerous yet diverging reports of associations between parental socioeconomic status (SES) and child cortical brain morphometry. Most of these studies have used single metric- or unimodal analyses of standard cortical morphometry that downplay the probable scenario where numerous biological pathways in sum account for SES-related cortical differences in youth.

Methods

To comprehensively capture such variability, using data from 9758 children aged 8.9-11.1 years from the ABCD Study®, we employed linked independent component analysis (LICA) and fused vertex-wise cortical thickness, surface area, curvature and grey-/white-matter contrast (GWC). LICA revealed 70 uni- and multimodal components. We then assessed the linear relationships between parental education, parental income and each of the cortical components, controlling for age, sex, genetic ancestry, and family relatedness. We also assessed whether cortical structure moderated the negative relationships between parental SES and child general psychopathology.

Results

Parental education and income were both associated with larger surface area and higher GWC globally, in addition to local increases in surface area and to a lesser extent bidirectional GWC and cortical thickness patterns. The negative relation between parental income and child psychopathology were attenuated in children with a multimodal pattern of larger frontal- and smaller occipital surface area, and lower medial occipital thickness and GWC.

Conclusion

Structural brain MRI is sensitive to SES diversity in childhood, with GWC emerging as a particularly relevant marker together with surface area. In low-income families, having a more developed cortex across MRI metrics, appears beneficial for mental health.

Across ages and places: Unpredictability of maternal sensory signals and child internalizing behaviors

BACKGROUND

Patterns of sensory inputs early in life play an integral role in shaping the maturation of neural circuits, including those implicated in emotion and cognition. In both experimental animal models and observational human research, unpredictable sensory signals have been linked to aberrant developmental outcomes, including poor memory and effortful control. These findings suggest that sensitivity to unpredictable sensory signals is conserved across species and sculpts the developing brain. The current study provides a novel investigation of unpredictable maternal sensory signals in early life and child internalizing behaviors. We tested these associations in three independent cohorts to probe the generalizability of associations across continents and cultures.

METHOD

The three prospective longitudinal cohorts were based in Orange, USA (n = 163, 47.2 % female, Mage = 1 year); Turku, Finland (n = 239, 44.8 % female, Mage = 5 years); and Irvine, USA (n = 129, 43.4 % female, Mage = 9.6 years). Unpredictability of maternal sensory signals was quantified during free-play interactions. Child internalizing behaviors were measured via parent report (Orange & Turku) and child self-report (Irvine).

RESULTS

Early life exposure to unpredictable maternal sensory signals was associated with greater child fearfulness/anxiety in all three cohorts, above and beyond maternal sensitivity and sociodemographic factors. The association between unpredictable maternal sensory signals and child sadness/depression was relatively weaker and did not reach traditional thresholds for statistical significance.

LIMITATIONS

The correlational design limits our ability to make causal inferences.

CONCLUSIONS

Findings across the three diverse cohorts suggest that unpredictable maternal signals early in life shape the development of internalizing behaviors, particularly fearfulness and anxiety.

Anxiety and Depression from Childhood to Young Adulthood: Trajectories and Risk Factors

This study aimed to (1) evaluate how population levels of anxiety and depression grow and correlate from middle childhood through early adulthood, and (2) determine whether sex, family socioeconomic status, parental education, academic achievement, learning disabilities, or externalizing symptoms predict anxiety and/or depression levels and growth trajectory. We used two longitudinal samples (N = 445, 448) of Portuguese children. Mean depression levels increased from mid-childhood through adolescence before stabilizing in early adulthood and were most strongly predicted by academic achievement and learning disabilities. Mean anxiety levels increased until adolescence before decreasing across early adulthood and were most strongly predicted by academic achievement, learning disabilities, and externalizing symptoms. Quadratic models of growth fit best for both depression and anxiety, and depression and anxiety growth trajectories were strongly correlated. Though anxiety and depression trajectories differ in pattern and predictors, the two are highly interrelated and pathways to comorbid anxiety and depression should be characterized.

The Role of Resilience in the Impact of Family Economic Adversity on Youth Emotional Distress over Time

Previous research has highlighted the enduring negative impact of family economic adversity on youth emotional well-being. However, the longitudinal mechanism underlying the link between economic adversity and emotional distress is less explored. The present study examined the longitudinal pathway of parent economic adversity, and parent and adolescent emotional distress at age 16, parental support at age 21, youth self-esteem and mastery at age 23, and adult emotional distress at age 27. Data came from the Family Transitions Project (N = 441, 57% female), a 30-year study of families from the rural Midwest. Structural equation models revealed that economic adversity exerted a long-term negative influence on adult emotional well-being through parent and adolescent emotional distress and youth self-esteem and mastery. Additionally, parental support was associated with adult emotional distress through youth self-esteem and mastery. The current study advances our understanding of youth emotional well-being by suggesting a longitudinal family process and resilience pathways from adolescence to early adulthood.

Novel word learning ability in 24-month-olds: The interactive role of mother's work status and education level

Using both online and offline measures, this study investigates how maternal education and work status (stay-at-home, part-time, full-time) are jointly associated with infants' word learning ability and vocabulary size. One hundred 24-month-old infants completed a lab-based mutual exclusivity task, which assesses infants' novel word learning ability. Caregivers reported infants' productive vocabulary size using the MCDIs. There was no evidence for an association between infants' productive vocabulary size and maternal education, maternal work status, or their interaction. However, infants' novel word learning ability was significantly related to both maternal factors and their interaction. The positive association between maternal education and word learning performance was attenuated for infants of part-time and full-time working mothers compared to infants with at home mothers. These findings suggest that using real-time measures with high task demand may better capture developmental differences in infants and expand our understanding of maternal factors contributing to early language development.

The relation between family socioeconomic status and depressive symptoms among children and adolescents in mainland China: a meta-analysis

Family socioeconomic status (SES) is widely believed to be associated with depressive symptoms in children and adolescents. The correlation between SES and depressive symptoms changes based on social culture and the economic development level. In China, which includes many children and adolescents, the magnitude of the relationship between SES and depressive symptoms and its potential moderators remains unclear. The current meta-analysis was conducted to determine the overall association between SES and depressive symptoms in children and adolescents in mainland China. We included 197 estimates in mainland China from 2000-2023. Among 147,613 children and adolescents aged 7-18 years, the results showed a weak but significant overall negative association between SES and depression (r = -0.076). Moderator testing showed that the composite SES indicator (r = -0.104) had a stronger association with depression than parental educational level (r = -0.065) and occupational status (r = -0.025) but not family income (r = -0.088). Additionally, the negative association between SES and depression became weaker over the past 20 years in China (β = 0.010). Furthermore, the magnitude of the relationship between SES and depression was stronger in West China (r = -0.094) than in Middle China (r = -0.065), but not East China (r = -0.075). These findings indicate that the relationship between SES and depression among children and adolescents in mainland China may vary based on social contexts. It is necessary to further explore the effect of these social factors and the underlying mechanisms.

Early child development and its determinants: Findings from a large cohort of healthy children growing up in a low-risk environment

BACKGROUND

Despite numerous studies on early child development, there is still much to be discovered about the significance of possible risk factors. This study examines cognitive, motor, and language development of healthy children growing up in a low-risk environment and how various individual and environmental factors are associated with it. The study also considers whether the importance of particular parameters changes depending on child age.

METHODS

Within the framework of the LIFE Child study in Leipzig, Germany, 481 children participated in a total of 832 visits between 1 and 36 months of age. Developmental status was assessed using the Third Edition of the Bayley Scales of Infant and Toddler Development. Linear regression analyses were applied to examine the associations between child development and sex, gestational age, birth weight, birth mode, overweight, height, and parental education.

RESULTS

Mean Bayley composite scores for cognitive, language, and motor development were close to the standard value of 100. Poorer developmental outcomes were significantly associated with lower gestational age, vacuum cup/forceps birth, being overweight, small height, and lower parental education, although some of the associations became insignificant after applying multivariate models. While the association between gestational age and language development became weaker with advancing age, our interaction models found disparities related to parental education to become more apparent in older children across all three domains of early child development.

CONCLUSIONS

Several factors were identified to be associated with early child development. As children grow older, obstetric parameters, for example, gestational age, might become less relevant compared with sociodemographic factors, for example, parental education.

Sleep duration in preschool age and later behavioral and cognitive outcomes: an individual participant data meta-analysis in five European cohorts

Short sleep duration has been linked to adverse behavioral and cognitive outcomes in schoolchildren, but few studies examined this relation in preschoolers. We aimed to investigate the association between parent-reported sleep duration at 3.5 years and behavioral and cognitive outcomes at 5 years in European children. We used harmonized data from five cohorts of the European Union Child Cohort Network: ALSPAC, SWS (UK); EDEN, ELFE (France); INMA (Spain). Associations were estimated through DataSHIELD using adjusted generalized linear regression models fitted separately for each cohort and pooled with random-effects meta-analysis. Behavior was measured with the Strengths and Difficulties Questionnaire. Language and non-verbal intelligence were assessed by the Wechsler Preschool and Primary Scale of Intelligence or the McCarthy Scales of Children's Abilities. Behavioral and cognitive analyses included 11,920 and 2981 children, respectively (34.0%/13.4% of the original sample). In meta-analysis, longer mean sleep duration per day at 3.5 years was associated with lower mean internalizing and externalizing behavior percentile scores at 5 years (adjusted mean difference: - 1.27, 95% CI [- 2.22, - 0.32] / - 2.39, 95% CI [- 3.04, - 1.75]). Sleep duration and language or non-verbal intelligence showed trends of inverse associations, however, with imprecise estimates (adjusted mean difference: - 0.28, 95% CI [- 0.83, 0.27] / - 0.42, 95% CI [- 0.99, 0.15]). This individual participant data meta-analysis suggests that longer sleep duration in preschool age may be important for children's later behavior and highlight the need for larger samples for robust analyses of cognitive outcomes. Findings could be influenced by confounding or reverse causality and require replication.

Socioeconomic inequalities in early child development in children aged under 36 months in South Asia: A systematic review

BACKGROUND

In South Asia, 89 million children under 5 are at risk of not reaching their developmental potential. Household socioeconomic position (SEP) is a determinant of early child development (ECD). However, synthesised evidence for the association between ECD and SEP in young children in South Asia is not available. Therefore, this review synthesises evidence on the relationship of household SEP with ECD in children under 36 months of age in South Asia.

METHOD

PubMed, Cochrane Library, MEDLINE and Scopus were systematically searched to identify studies from South Asian countries that reported evidence on the association between SEP and ECD. Search terms included items related to motor, cognitive, language and socioemotional development. Study quality was assessed using the QualSyst tool, with three quality levels (high/medium/low), and a narrative review for each ECD outcome was constructed (PROSPERO registration: CRD42019131533).

RESULTS

Twelve of the 950 publications screened met the inclusion criteria (nine from India, two Nepal and one Bangladesh). The majority (n = 10, 83%) reported language development on its own or alongside another ECD outcome. Fewer articles assessed cognitive (n = 6, 50%), motor (n = 7, 58%) or socioemotional development (n = 3, 25%). Higher SEP was associated with better ECD for one third of the associations reported. One ECD outcome (socioemotional development) was negatively associated (with socioeconomic status) based on low quality evidence. Mother's education and family income were the major SEP constructs associated with ECD. One, four and seven studies were rated as having a low, medium and high risk of bias, respectively.

CONCLUSION

This review reveals the scarcity of evidence exploring associations between household SEP and ECD in children under 36 months in South Asia, especially outside of India. Enhancing evidence for associations between ECD and SEP is needed for evidence-based policy making to reduce developmental delays associated with a disadvantaged SEP in the South Asian region.

Love withdrawal use by toddlers: Multi-informant associations with aggression and parents' use of love withdrawal

Love withdrawal is a form of interpersonal manipulation that shares many features with relational aggression; its use by children has not been examined. Guided by social learning theory, we sought to investigate the prevalence of toddlers' use of love withdrawal toward caregivers (parents and teachers) and further investigate how this behavior was associated with relational and physical aggression and parents' use of love withdrawal. These aims were examined using parent and teacher reports in a sample of 198 toddlers (Mage  = 33.62 months; SD = 5.00 months; 50.5% girls). We found that most toddlers used love withdrawal directed at parents (79.2%) and teachers (72.1%) when angry and displayed this type of behavior more than relational and physical aggression. Accounting for household income, hours per week in childcare, and child age in months, as well as classroom clustering, we found that relational aggression, and not physical aggression, predicted the use of love withdrawal by toddlers (teacher reports), and that the associations were stronger for love withdrawal and relational aggression than for physical aggression. We also found that parents' use of love withdrawal toward their child was correlated with their reports of their child's use of love withdrawal, but not with their child's use of aggression. These results highlight the importance of considering the use of love withdrawal by children given its association with aggression which is linked to poorer psychosocial functioning.

Early childhood trajectories of domain-specific developmental delay and gestational age at birth: An analysis of the All Our Families cohort

OBJECTIVE

To describe developmental domain-specific trajectories from ages 1 through 5 years and to estimate the association of trajectory group membership with gestational age for children born between ≥34 and <41 weeks gestation.

METHODS

Using data from the All Our Families cohort, trajectories of the domain-specific Ages & Stages Questionnaire scores were identified and described using group-based trajectory modeling for children born ≥34 and <41 weeks of gestation (n = 2664). The trajectory groups association with gestational age was estimated using multinomial logistic regression.

RESULTS

Across the five domains, 4-5 trajectory groups were identified, and most children experienced changing levels of risk for delay over time. Decreasing gestational age increases the Relative risk of delays in fine motor (emerging high risk: 1.46, 95% CI: 1.19-1.80; resolving moderate risk: 1.11, 95% CI: 1.03-1.21) and gross motor (resolving high risk: 1.21, 95% CI: 1.04-1.42; and consistent high risk: 1.64, 95% CI: 1.20-2.24) and problem solving (consistent high risk: 1.58 (1.09-2.28) trajectory groups compared to the consistent low risk trajectory groups.

CONCLUSION

This study highlights the importance of longitudinal analysis in understanding developmental processes; most children experienced changing levels of risk of domain-specific delay over time instead of having a consistent low risk pattern. Gestational age had differential effects on the individual developmental domains after adjustment for social, demographic and health factors, indicating a potential role of these factors on trajectory group membership.

Impact of school SES on literacy development

Effective literacy skills are essential to actively participate in today's society. However, little research has been conducted that examined the impact of contextual variables on literacy development. The present paper addressed whether and how the socioeconomic status of the school (S-SES) children attend affects their literacy achievements. Eight-hundred and seventy-eight 2nd and 4th grade children participated in the study. Data were collected in low-SES (vulnerable) and in mid-high-SES (non-vulnerable) schools. Children completed a large battery of language, cognitive, and literacy tasks in Catalan, a language spoken in a region in Spain where virtually all children are at least bilingual (they also speak Spanish) and it is the main language of instruction. Results showed that children in vulnerable schools were outperformed by children in non-vulnerable schools across all literacy competencies, but particularly affected higher order skills; that is, text quality and reading comprehension. Differences with their non-vulnerable peers remained, even after controlling for context-level covariates, including familial SES. However, S-SES ceased to exert significant influence once children's cognitive and, especially, linguistic skills were considered. The study adds to previous research claiming that school SES has an effect on students' literacy skills, above and beyond children's home SES. However, our findings also suggest that literacy performance is ultimately mostly dependent on educationally actionable, subject-level skills. Educational implications are discussed.

Mind-mindedness and styles of interaction of young fathers with their infants at three months: a pilot study

BACKGROUND

Fatherhood at a young age can be characterized by a multiproblematic background with several risk factors that can negatively affect father-child relationships, the father's well-being and child's social-emotional development.

METHODS

This pilot study evaluated paternal interaction styles and mentalization in a sample of 22 young fathers and their 3-month-old infants and compared these variables with those of 22 adolescent and young mothers (the fathers' partners). Parent-infant interaction were codified with Care-Index to evaluate styles of interaction and with Mind-Mindedness system to evaluate mentalization.

RESULTS

The results showed that young fathers had high scores in controlling behaviors and low scores in sensitivity, placing them in a risk range. The young father's interaction profile did not differ from the young mother's interaction profile. Infants had high scores in passive behaviors and low scores in cooperative behaviors, placing them in a high-risk range. Moreover, young fathers had more nonattuned mind-related comments than their partners.

CONCLUSIONS

The findings indicate that low responsiveness and low mind-mindedness characterize the quality of adolescent and young father-infant interactions, highlighting the value of providing early intervention to support the father-child relationship, enhancing the father's sensitivity and his ability to keep the infant in mind.

Measuring adolescent health literacy in Taiwan: validation of the health literacy assessment scale for adolescents

BACKGROUND

This study aimed to validate the Chinese version of the Health Literacy Assessment Scale for Adolescents (HAS-A) and conduct a comparative analysis of adolescent health literacy between Taiwan and other countries.

METHODS

The Chinese version of the HAS-A was completed by 2,312 adolescents in the fifth and sixth grades of a primary school. Psychometric properties were examined using consistent internal reliability and confirmatory factor analysis. These assessments were compared with the results from different regions to explore health literacy inequality.

RESULTS

Construct validity was good, and internal consistency was acceptable. The scale, particularly regarding communication health literacy, was associated with parents' socioeconomic status, and family income had a more significant impact on children's health literacy than community income. Health literacy disparities appear in different countries, with Taiwan exhibiting the lowest level of communication health literacy.

CONCLUSION

The results indicate that the HAS-A is a valuable tool for assessing the health literacy of 10-11-year-old adolescents and can uncover health literacy inequality among different regions.

[Effects of High Birth Weight on the Development of Preschoolers]

BACKGROUND

A high birth weight above 4,000 g may lead to risks in the development of affected children. The association is less studied than the effects of very low birth weight and is the subject of this study.

METHODS

The retrospective study design used data from school entry surveys in Schleswig-Holstein (Germany) collected in 2014-2017 and included 88,858 children aged 5-6 years. End points examined were language, motor skills, cognition, and behavior; use of support measures; and recommendation for special educational needs. Logistic regression models were used to estimate the association between birth weight and the outcome measures, adjusting for sociodemographic factors.

RESULTS

After accounting for sociodemographic factors, high birth weight is not associated with impaired child development, whereas low birth weight emerges as a significant predictor. Across all birth weights, sociodemographic factors explain most of the variance in multivariate models of the influence of birth weight on child development.

CONCLUSIONS

Very high birth weight does not justify a general recommendation for support measures. Therefore, individual developmental trajectories should be monitored. Growing up in disadvantaged circumstances may represent a significant risk and should be a reason for early intervention.

Proximal determinants of suboptimal early child development during the first three years of life in socially deprived Mexican contexts

Assessing the status and determinants of early child development (ECD) requires accurate and regularly updated measurements. Yet, little information has been published on the subject in low- and middle-income countries, particularly regarding the proximal determinants of childhood development in contexts of high social marginalization. This article analyzes the factors that favor or mitigate suboptimal ECD outcomes in Mexico. A cross-sectional study was conducted using recently collected data for 918 children aged 0-38 months from socially marginalized communities in 23 Mexican municipalities. The ECD outcomes of the children were estimated based on indicators of chronic undernutrition and neurodevelopment (normal, lagging and at risk of delay). The distribution of outcomes was described across the ECD proximal determinants analyzed, including the co-occurrence of chronic undernutrition and suboptimal neurodevelopment. Covariate-adjusted prevalence of the ECD outcomes and co-occurrences were calculated as post-estimations from a multiple multinomial logistic regression. The prevalence of chronic undernutrition was 23.5%; 45.9% of children were classified with neurodevelopmental lag, and 11% at risk of neurodevelopmental delay. The prevalence of stunting co-occurring with suboptimal neurodevelopment came to 15.4%. The results of the multinomial logistic regression model indicated that early gestational age, low birth weight, a low household socioeconomic level, being male and having numerous siblings were all associated with the co-occurrence of chronic undernutrition and suboptimal child neurodevelopment. This study identified important predictors of child development in the first three years of life, specifically in two of its principal indicators: nutritional and neurodevelopmental status. Most of the predictors observed can be improved by means of social programs and interventions. Trial registration: ClinicalTrials.gov ID: NCT04210362.

Maternal Mental Health and Children's Problem Behaviours: A Bi-directional Relationship?

Transactional theory and the coercive family process model have illustrated how the parent-child relationship is reciprocal. Emerging research using advanced statistical methods has examined these theories, but further investigations are necessary. In this study, we utilised linked health data on maternal mental health disorders and explored their relationship with child problem behaviours via the Strengths and Difficulties Questionnaire for over 13 years. We accessed data from the Millennium Cohort Study, linked to anonymised individual-level population-scale health and administrative data within the Secure Anonymised Information Linkage (SAIL) Databank. We used Bayesian Structural Equation Modelling, specifically Random-Intercept Cross-Lagged Panel Models, to analyse the relationships between mothers and their children. We then explored these models with the addition of time-invariant covariates. We found that a mother's mental health was strongly associated over time, as were children's problem behaviours. We found mixed evidence for bi-directional relationships, with only emotional problems showing bi-directional associations in mid to late childhood. Only child-to-mother pathways were identified for the overall problem behaviour score and peer problems; no associations were found for conduct problems or hyperactivity. All models had strong between-effects and clear socioeconomic and sex differences. We encourage the use of whole family-based support for mental health and problem behaviours, and recommend that socioeconomic, sex and wider differences should be considered as factors in tailoring family-based interventions and support.

The impact of family functioning on depression in college students: A moderated mediation model

BACKGROUND

The depression of college students is increasing. Family dysfunction is a potential risk factor for depression. More research is needed to uncover the relationship and influencing mechanism. Based on this, this study examined the mediating effect of coping style and the moderating effect of gender in family functioning and depression among college students.

METHODS

From May to June 2022, a cross-sectional survey was conducted among 2033 college students (16-24 years old) from universities in Anhui Province, China, including 1285 females (63.21 %) and 748 males (36.79 %), with an average age of 19.81 years old (SD = 1.22 years old). There were 651 (32.02 %) only child. Family functioning was assessed by Family Assessment Device, coping style was assessed by Simplified Coping Style Questionnaire and depression was assessed by Self-rating Depression Scale. Common method bias was performed by Harman's single-factor test. Mediating effect was analyzed by stepwise regression. Moderating effect was analyzed by moderated multiple regression.

RESULTS

There was no serious common method bias in this study. Good family functioning had a negative predictive effect on depression in college students (r = -0.56, p < 0.001). Coping style partially mediated the predictive effect of family functioning on depression, and the mediating effect accounted for 33.73 % of the total effect. The interaction term of family functioning and gender was significant predictor of coping style (β = 0.33, t = 2.69, p < 0.05) and depression (β = -1.98, t = -2.46, p < 0.05).

CONCLUSIONS

Good family functioning is a negative predictor of depression in college students. Coping style plays a partial mediating role between family functioning and depression. The first half path and the direct path of the mediation model are modulated by gender.

The influence of socioeconomic status and appearance-reality understanding on pre-schoolers' sharing and generosity

Prosocial behaviour can be defined as any voluntary action that is performed to benefit another individual. Despite accumulating evidence of the importance of environmental variables (e.g., socioeconomic status; SES), and individual characteristics (e.g., theory of mind - ToM - skills), in influencing prosocial behaviours in young children, it is unknown how these factors relate to the underlying motivations for prosocial behaviours. Accordingly, both extrinsically (sharing) and intrinsically (generosity)-guided prosocial behaviours are measured in this study. We explore the influences of SES and ToM skills on young children's sharing behaviour and generosity, while controlling their age, working memory and language skills. Sixty-six 4- to 6 year olds (Mage  = 5.24 years, SD = 0.73) from diverse SES (measured by parental education level) and ethnic backgrounds in Singapore completed tasks assessing the ToM measures of false belief and appearance-reality understanding, working memory, language skills, generosity, and sharing behaviour. The results of hierarchical regression analyses demonstrate that the father's education level and children's appearance-reality understanding were significant predictors of sharing, after controlling for age, working memory, language skills, and the mother's education level. Children's appearance-reality understanding was the sole predictor of children's generosity. Our findings highlight the impact of children's ability to hold different views of reality and their family's education levels on the development of sharing and generosity in early childhood.

Future-oriented cognition: links to mental health problems and mental wellbeing in preschool-aged and primary-school-aged children

Future-oriented cognition plays a manifold role for adults' mental health. The present study aimed to investigate the relationship between future-oriented cognition and mental health in N = 191 children aged between 3 and 7 years. Parents completed an online-questionnaire including children's future-oriented cognition (e.g., episodic foresight; Children Future Thinking Questionnaire; CFTQ), children's mental health problems (Strengths and Difficulties Questionnaire; SDQ), and wellbeing (Parent-rated Life Orientation Test of children; PLOT and Positive-Mental-Health Scale; PMH). More externalizing problems (especially hyperactivity) related to lower future-oriented cognition. For mental wellbeing, higher levels of optimism were associated with higher episodic foresight. Future-oriented cognition increased with age cross-sectionally. This increase was flatter at higher levels of wellbeing (indicated by lower pessimism). Results are discussed considering findings on the role of future-oriented cognition for mental health in adults and adolescents. Suggestions for future work are presented regarding the direction of the observed links and underlying mechanisms.

Psychosocial and Health-Related Experiences of Individuals With Microtia and Craniofacial Microsomia and Their Families: Narrative Review Over 2 Decades

This paper describes 20 years of microtia and craniofacial microsomia (CFM) psychosocial and healthcare studies and suggests directions for clinical care and research.

A narrative review of papers January 2000 to July 2021 related to psychosocial and healthcare experiences of individuals with microtia and CFM and their families.

Studies (N = 64) were mainly cross-sectional (69%), included a range of standardized measures (64%), and were with European (31%), American (27%), or multinational (23%) samples. Data were generally collected from both patients and caregivers (38%) or patient self-report (35%). Sample sizes were 11 to 25 (21%), 26 to 50 (19%), 51 to 100 (22%), or over 100 (38%). Studies addressed 5 primary topics: (1) Healthcare Experiences, including Medical Care, Hearing Loss/Amplification, Diagnostic Experiences, and Information Preferences; (2) Psychosocial Experiences, including Teasing, Behavioral Adjustment, Psychosocial Support, and Public Perception; (3) Neurocognitive Functioning and Academic Assistance; (4) Pre- and Post-Operative Psychosocial Outcomes of Ear Reconstruction/Canaloplasty; and (5) Quality of Life and Patient Satisfaction.

Care involved multiple specialties and was often experienced as stressful starting at diagnosis. Psychosocial and neurocognitive functioning were generally in the average range, with possible risk for social and language concerns. Coping and resiliency were described into adulthood. Satisfaction and positive benefit of ear reconstruction/canaloplasty were high. Care recommendations include increasing: hearing amplification use, microtia and CFM knowledge among providers, efficient treatment coordination, psychosocial support, academic assistance, and advances to minimize surgical scarring. This broad literature overview informs clinical practice and research to improve psychosocial outcomes.

How household chaos affects social withdrawal of rural children: the indirect role of executive function and receptive language ability

Executive function (EF) and receptive language ability play an important role in the relationship between household chaos and social withdrawal. Young children are neglected in household chaos research and suffer from the negative outcomes of households in China. However, few studies have focused on the relationship between household chaos and social withdrawal in young Chinese children and the chain mediating effect of EF and receptive language ability. This study included 922 preschool-age children (62.58 ± 8.03 months) and their primary caregivers and their teachers were recruited from 21 rural preschools in Guangdong Province in China. Our results show a positive direct effect of household chaos and social withdrawal. Furthermore, an indirect sequential effect of household chaos and social withdrawal on EF and receptive language ability was found. Our findings (a) highlight the significance of paying more attention to household chaos and revealing a better understanding of the effect of EF and receptive language ability on households at an early age and (b) indicate that interventions should be provided to improve the home environment when children are young.

Socioeconomic Status Affects Postoperative Time to Union in Pediatric Patients with a Surgically Treated Fracture

Fractures account for 10% to 25% of all pediatric injuries, and surgical treatment is common. In such cases, postoperative healing can be affected by a number of factors, including those related to socioeconomic status (SES). The purpose of this study was to investigate the relationship between time to fracture union and SES, which was measured with use of the median household income (MHI) and Child Opportunity Index (COI).

Methods

A retrospective review was conducted of pediatric patients with a long-bone fracture that had been surgically treated at a Level-I pediatric trauma center between January 2010 and June 2020. Demographic and relevant medical data were collected. Patients were sorted into union and nonunion groups. The ZIP code of each patient was collected and the MHI and COI of that ZIP code were identified. Income brackets were created in increments of $10,000 ranging from $20,000 to $100,000, with an additional category of >$100,000, and patients were sorted into these groups according to MHI. Comparisons among the income groups and among the union status groups were conducted for each of the collected variables. A multiple regression analysis was utilized to determine the independent effect of each variable on time to union.

Results

A total of 395 patients were included in the final sample, of whom 51% identified as Hispanic. Patients in the union group had a higher mean COI and MHI. Nonunion occurred in only 8 patients. Patients who achieved fracture union in ≤4 months had a significantly higher mean COI and MHI. When controlling for other demographic variables, the time to union increased by a mean of 9.6 days for every $10,000 decrease in MHI and increased by a mean of 6.8 days for every 10-unit decrease in the COI.

Conclusions

The present study is the first, to our knowledge, to investigate the relationship between SES and time to fracture union in pediatric patients. When controlling for other demographic factors, we found a significant relationship between SES and time to union in pediatric patients with a surgically treated fracture. Further investigations of the relationship between SES and time to union in pediatric patients are needed to determine potential mechanisms for this relationship.

Maternal Diet Quality and Prenatal Depressive Symptoms: The Moderating Role of Economic Well-Being

Prenatal depression is prevalent and adversely impacts maternal and infant health. This study addresses a critical literature gap and investigates the association between maternal diet quality and prenatal depressive symptoms, as well as the moderating effect of economic well-being on this link. A cross-sectional design was used, including 43 healthy pregnant women in the second trimester aggregated from two research projects. Prenatal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale. Dietary quality was evaluated using two non-consecutive 24 h dietary recalls, from which the Adapted Dietary Inflammatory Index (ADII) and the Healthy Eating Index (HEI)-2015 were derived. Economic well-being was indicated by the income-to-poverty ratio. A higher HEI-2015 (adherence to dietary guidelines; β = -0.53, p = 0.01) and negative ADII (anti-inflammatory diet; β = 0.40, p = 0.06) were associated with fewer prenatal depressive symp-toms. Among pregnant women with worse economic well-being, a pro-inflammatory diet was as-sociated with more prenatal depressive symptoms (b = 1.69, p = 0.004), but among those with better economic well-being, the association was not significant (b = 0.51, p = 0.09). Dietary interventions aimed at reducing dietary inflammation might hold some promise for improving mental health among pregnant women who are economically vulnerable.

The social gradient in adolescent mental health: mediated or moderated by belief in a just world?

PURPOSE

A social gradient in adolescent mental health exists: adolescents with higher socioeconomic status (SES) have fewer mental health problems than their peers with lower SES. Little is known about whether adolescents' societal beliefs play a role in this social gradient. Belief in a just world (BJW) may be a mediator or moderator of the social gradient in adolescent mental health.

METHODS

Using data from 848 adolescents (Mage = 17) in the Netherlands, path analyses examined whether two indicators of BJW (general and personal) mediated or moderated the associations between two indicators of SES (family affluence and perceived family wealth), and four indicators of adolescent mental health problems (emotional symptoms, conduct problems, hyperactivity, and peer problems).

RESULTS

Adolescents with lower family affluence and lower perceived family wealth reported more emotional symptoms, and the association between perceived family wealth and emotional symptoms was mediated by lower personal and general BJW. Furthermore, higher personal BJW amplified the negative association between SES and peer problems.

CONCLUSION

This study suggests BJW may both mediate and amplify the social gradient in adolescent mental health. Adolescents' beliefs about society may be important to include in research aimed at understanding this social gradient.

Investigating the Link Between Depression, Cognition, and Motivation in Late Childhood

Research has revealed broad cognitive deficits (e.g., memory, learning) in depression, and that motivation may account for this link. We tested the state (i.e., only present during depression), trait (i.e., underlying vulnerability) and scar (i.e., lasting corollary) hypotheses of cognitive dysfunction in depression. We additionally tested subjective motivation as a mediator of the concurrent depression-cognition link. In a longitudinal sample of 11,878 children ages 9-11, we found no evidence of a concurrent state or longitudinal trait or scar relationship between depression and cognition. The pattern of depression-cognition relationships-which precluded a mediator analysis-in our childhood sample is a departure from previous studies. Our findings indicate that cognitive deficits are not strongly associated with depression in childhood, in contrast with the impairment commonly seen in older individuals with depression.

Longitudinal Relation between Family Socio-Economic Status and Problem Behaviors in Chinese Children: The Roles of Sense of Coherence and Maternal Warmth

Literature has well-documented the relation of family socio-economic status (SES) to children’s problem behaviors, yet the complex mechanisms underlying the relation are not well understood. Therefore, the primary goal of this one-year longitudinal study was to explore the mediating role of children’s sense of coherence and the moderating role of perceived maternal warmth in the association between family SES and externalizing and internalizing problems in Chinese children. The sample consisted of 913 children (493 boys; Mage = 11.50 years, SD = 1.04) in fourth to sixth grades in an urban area in mainland China. Data were obtained from multiple sources, including child self-reports, parental reports, and teacher ratings. The results indicated that children’s sense of coherence mediated the association between family SES and internalizing problem behaviors, but not externalizing problem behaviors. This mediating role was also moderated by maternal warmth and specifically, family SES was negatively associated with internalizing problem behaviors via the sense of coherence for children who perceived high maternal warmth. Generally, these results highlighted the possible roles of a sense of coherence and maternal warmth in the longitudinal implications of family SES for Chinese children’s internalizing problems.
