Occupational exposure to organic solvents during pregnancy and child behavior from early childhood to adolescence

BackgroundOrganic solvents are used in formulating an extensive range of products for professional use. Animal and human studies suggest that in utero solvent exposure may affect neurodevelopment. Our objective was to assess the association between occupational exposure to solvents during pregnancy and child behavior aged 2–12 years.MethodsThe French mother-child cohort PELAGIE (2002–2006) included 3,421 women recruited in early pregnancy. Occupational exposure to solvents was self-reported. For 459 children, parents used a questionnaire derived from the Child Behavior Checklist and the Preschool Social Behavior Questionnaire to assess their child’s behavior, at age 2, and the Strengths and Difficulties Questionnaire at ages 6 and 12. A cross-lagged structural equation modeling approach was used to assess direct and indirect associations between exposure and child behavior.ResultsAt age 2, an increased externalizing behavior score was suggested with prenatal exposure to solvents (mean change in standardized score (95%CI): 0.28 (-0.01, 0.57) for occasional exposure and 0.23 (-0.05, 0.51) for regular exposure). At ages 6 and 12, distinct sex-specific patterns were observed: among boys, no association with externalizing behavior was observed, while among girls, an association was seen for both occasional and regular exposure (total effect at age 12: 0.45 (0.06,0.83) and 0.40 (0.03, 0.76), respectively). For both sexes, occasional exposure may be associated with internalizing behavior at ages 6 and 12 (total effect at age 6: 0.37 (0.06, 0.68) and at age 12: 0.27 (-0.08, 0.62)).ConclusionsOccupational exposure to solvents during pregnancy may impact child behavior through either direct or cumulative effects during childhood; these associations may persist until early adolescence, especially among girls.

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

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). 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. 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). 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.

Within-child associations between sleep quality and emotional self-regulation over 6 months among preschool-aged (3- to 5-year-old) children

ObjectiveWe leveraged an observational, repeated-measures study to examine the within-child associations between sleep quality and emotional self-regulation, controlling for between-child effects.MethodsChildren aged 3–5 years and one parent each were recruited from the community in northern New England between 2019 and 2022. Parents completed online surveys at baseline and 2, 4, and 6 months post-baseline. Child sleep quality was measured with the validated Children's Sleep Habits Questionnaire modified for preschoolers; higher scores indicate worse sleep quality (range 32–96). Child emotional self-regulation was measured with the validated Child Social Behavior Questionnaire; higher scores indicate better emotional self-regulation (range 1–7). Adjusted mixed-effects linear regression was used to model the associations between nighttime sleep quality (exposure) and emotional self-regulation (outcome) measured at each of the four study time points while disaggregating the between- and within-child effects.ResultsChildren (n = 91) were largely white, non-Hispanic (88.7%), and from a higher social-economic status. Sleep quality scores averaged 38.9 (SD: 6.6) at baseline; 23.1% of children had scores &amp;gt;41, which is considered evidence of significant sleep problems. Emotional self-regulation scores averaged 4.2 (SD: 1.0). There was a significant within-child association between sleep quality and emotional self-regulation. Specifically, a decrease in sleep quality at any one time point, relative to each child's mean sleep quality, related to worse emotional self-regulation [standardized beta, βs = −0.31; 95% CI (0.53, −0.09)]; the between-child effect was not significant. Results were consistent when limited to children with complete data at all study visits (n = 78).ConclusionsThe findings support a causal, within-child association between sleep quality and emotional self-regulation in preschool-aged children, with effects evident over 6 months.

Measuring Antisocial Behaviors in Behavioral Variant Frontotemporal Dementia With a Novel Informant-Based Questionnaire.

Antisocial behaviors are common and problematic among patients with behavioral variant frontotemporal dementia (bvFTD). In the present study, the investigators aimed to validate an informant-based questionnaire developed to measure the extent and severity of antisocial behaviors among patients with dementia. The Social Behavior Questionnaire (SBQ) was developed to measure 26 antisocial behaviors on a scale from absent (0) to very severe (5). It was administered to 23 patients with bvFTD, 19 patients with Alzheimer's disease, and 14 patients with other frontotemporal lobar degeneration syndromes. Group-level differences in the presence and severity of antisocial behaviors were measured. Psychometric properties of the SBQ were assessed by using Cronbach's alpha, exploratory factor analysis, and comparisons with a psychopathy questionnaire. Cluster analysis was used to determine whether the SBQ identifies different subgroups of patients. Antisocial behaviors identified by using the SBQ were common and severe among patients with bvFTD, with at least one such behavior endorsed for 21 of 23 (91%) patients. Antisocial behaviors were more severe among patients with bvFTD, including the subsets of patients with milder cognitive impairment and milder disease severity, than among patients in the other groups. The SBQ was internally consistent (Cronbach's α=0.81). Exploratory factor analysis supported separate factors for aggressive and nonaggressive behaviors. Among the patients with bvFTD, the factor scores for aggressive behavior on the SBQ were correlated with those for antisocial behavior measured on the psychopathy scale, but the nonaggressive scores were not correlated with psychopathy scale measures. The k-means clustering analysis identified a subset of patients with severe antisocial behaviors. The SBQ is a useful tool to identify, characterize, and measure the severity of antisocial behaviors among patients with dementia.

Drivers of the socio-economic disadvantage gap in England: Sequential pathways that include the home learning environment and self-regulation as mediators.

Socio-economic status (SES) is a powerful predictor of attainment. Research has identified multiple mechanisms that underpin the effect of SES on attainment. For example, self-regulation (processes through which individuals direct and control their attention, emotion and behaviour) has been identified as one mechanism mediating the SES attainment gap. However, previous studies have not directly tested the statistical pathways by which children from lower SES backgrounds develop low self-regulation skills and subsequently poor attainment at the end of primary school. Adding the home learning environment, which is associated with both SES and self-regulation, further fleshes out the longitudinal pathways. We propose and test a new model where the relationship between SES and school attainment is sequentially mediated by the family home learning environment and the child's self-regulation. This study uses the Effective Pre-school, Primary and Secondary Education data set to study 2311 English children. We measured SES (via socio-economic disadvantage) based on an index of low parental education, occupation and income at age 3+. The home learning environment was measured by the Home Learning Environment Index at age 3+; self-regulation was a teacher report on the Child Social Behaviour Questionnaire at age 4+ and attainment was measured via scores on national assessments of English and Maths at age 11. Our measure of disadvantage predicted attainment. The home learning environment predicted children's self-regulation skills. The relationship between disadvantage and attainment was sequentially mediated by the home learning environment and self-regulation. These findings suggest that home learning environment and self-regulation may play a sequential role in perpetuating socio-economic disparities in education.

Changes in Early Childhood Irritability and Its Association With Depressive Symptoms and Self-Harm During Adolescence in a Nationally Representative United Kingdom Birth Cohort

This study aimed to investigate longitudinal associations between changes in early childhood irritability, and depressive symptoms and self-harm at 14 years. We used data from 7,225 children in a UK-based general population birth cohort. Childhood irritability was measured at 3, 5, and 7 years using 4 items from 2 questionnaires (the Children's Social Behaviour Questionnaire [CSBQ] and the Strengths and Difficulties Questionnaire [SDQ]). Participants reported depressive symptoms via the short Mood and Feelings Questionnaire (sMFQ) and self-harm via a single-item question, at 14 years. We used multilevel models to calculate within-child change in irritability between 3 and 7 years and examined associations between irritability, and depressive symptoms and self-harm at 14 years using linear and logistic regression models, respectively. We adjusted for child and family sociodemographic/economic characteristics, mental health difficulties, and child cognitive development. Irritability at ages 5 and 7 years was positively associated with depressive symptoms and self-harm at age 14 years. Irritability that remained high between 3 and 7 years was associated with depressive symptoms and self-harm at 14 years in unadjusted (depressive symptoms: β coefficient= 0.22, 95 % CI= 0.08-0.37, p= .003; self-harm: odds ratio= 1.09, 95 % CI= 1.01-1.16, p= .019) and adjusted models (depressive symptoms: β coefficient= 0.31, 95 % CI= 0.17-0.45, p< .001; self-harm: odds ratio= 1.12, 95 % CI= 1.0.4-1.19, p= .004). Results were similar in imputed samples. Children with irritability that remains high between 3 and 7 years are more likely to report higher depressive symptoms and self-harm during adolescence. These findings support early intervention for children with high irritability and universal interventions in managing irritability for parents of preschool-aged children.

Sex-Specific Dietary Patterns and Social Behaviour in Low-Risk Individuals.

Dietary and social behaviour are non-medical factors that influence health outcomes. Non-communicable diseases are related to dietary patterns. To date, little is known about how social behaviour is associated with health-related dietary patterns, and, in particular, we lack information about the role of sex within this possible relation. Our cross-sectional study investigated associations between dietary patterns and social behaviour including personality traits (self-control, risk taking), political preferences (conservative, liberal, ecological, social) and altruism (willingness to donate, club membership, time discounting) in men and women. We performed sex-specific correlation analyses to investigate relationships between dietary patterns based on self-reported protocols from the Mediterranean Diet Adherence Screener (MEDAS) and the validated Healthy Eating Index (HEI) from the EPIC Study and a self-reported social behaviour questionnaire. In linear regression models, we analysed associations between dietary and social behaviour patterns. Sex differences were measured by interaction analysis for each social behaviour item. The study sample consisted of N = 102 low-risk individuals. The median age of the study participants was 62.4 (25th/75th percentile 53.6, 69.1) years, and 26.5% were women. Analyses showed that a lower HEI score was correlated with a higher BMI in both women and men. MEDAS and HEI showed a positive correlation with each other in men. In men, a higher MEDAS showed a positive correlation when they estimated their ability as high, with the same for self-control and preference for ecological politics and MEDAS. A weak negative correlation has been shown between men with a preference for conservative politics and MEDAS. HEI showed a positive significant correlation with age in men. Male participants without club membership scored significantly higher in the HEI compared to non-members. A negative correlation was shown for time discounting in men. Linear regression models showed positive associations between preferences for ecological-oriented politics and nutrition for both HEI and MEDAS. No sex interactions were observed. We faced a few limitations, such as a small sample size, particularly for women, and a limited age spectrum in a European cohort. However, assuming that individuals with a preference for ecological-oriented politics act ecologically responsibly, our findings indicate that ecological behaviour in low-risk individuals might determine, at least in part, a healthy diet. Furthermore, we observed dietary patterns such as higher alcohol consumption in men or higher intake of butter, margarine and cream in women that indicate that women and men may have different needs for nutritional improvement. Thus, further investigations are needed to better understand how social behaviour affects nutrition, which could help to improve health. Our findings have the potential to inform researchers and practitioners who investigate the nature of the relationship between social behaviour and dietary patterns to implement strategies to create first-stage changes in health behaviour for individuals with a low cardiovascular risk profile.

Longitudinal effects of environmental noise and air pollution exposure on autism spectrum disorder and attention-deficit/hyperactivity disorder during adolescence and early adulthood: The TRAILS study

BackgroundExposure to ambient noise and air pollution may affect the manifestation and severity of Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). However, evidence is limited, and most studies solely assessed environmental exposures during pregnancy and early childhood. ObjectiveTo examine the longitudinal effects of ambient noise and air pollutants on ASD and ADHD symptom severity during adolescence and early adulthood. MethodsUsing a longitudinal design, we included 2750 children between 10 and 12 years old from the TRacking Adolescents' Individual Lives Survey (TRAILS) in the Netherlands, who were assessed in 6 waves from 2001 to 2017. ASD was measured by the Children's Social Behavior Questionnaire and the Adult Social Behavior Questionnaire. ADHD was measured by Child Behavior Checklist and the Adult Behavior Checklist. Ambient noise and air pollution exposures, including Ozone (O3), soot, sulfur dioxide (SO2), nitrogen dioxide (NO2), particulate matter 2.5 (PM2.5), and PM10 were modeled at the residential level according to standardized protocols. The longitudinal associations between exposures and symptom outcomes were examined using linear mixed models. ResultsWe found evidence that higher levels of exposure to PM were associated with more severe ASD and ADHD symptoms. This association decreased over time. We did not observe any other consistent associations of noise or other air pollutants with ASD and ADHD severity. ConclusionThe current study provides evidence for the negative impact of PM on ASD and ADHD symptoms. We did not find evidence of the negative health impact of other air pollutants and noise exposures on ASD or ADHD symptoms. Our study adds more evidence on the presence of associations between PM air pollution and neurodevelopmental diseases among adolescents and young adults.

Protocol for the Open Sky School: a two-arm clustered randomized controlled trial to test the effectiveness of a nature-based intervention on mental health of elementary school children

BackgroundThis article outlines the protocol for a trial to test the effectiveness of a nature-based intervention called Open Sky School to reduce mental health problems among elementary school children. Experimental studies show that contact with nature (e.g. walks in parks) improve mental health. A growing number of teachers have been applying outdoor education within the regular school curriculum and evidence suggests that such teaching methods could improve students’ mental health but a randomized controlled trial has never been conducted.MethodsA two-arm clustered randomized controlled trial will be conducted in elementary schools across Québec, Canada. Following informed consent by teachers, parents and students, schools will be randomly assigned 1:1 to the intervention or the control group with a total of 2500 5-6th grade students and 100 teachers expected to participate. The intervention will take place outdoors in a green-space (2 h per week for 12 weeks) and include a toolkit of 30 activities to foster well-being (e.g. mindfulness) and academic competencies (e.g. mathematics). Questionnaires will be administered to teachers and students before, immediately after and 3 months after the intervention. The primary outcome will be reductions of mental health problems in children from pre-to-post test (Social Behavior Questionnaire: self and teacher reports). Secondary outcomes include depression, positive and negative affect, nature connectedness, and pro-environmental behaviors among children. We will explore, immediate benefits on teacher’s well-being and positive and negative affect and sustained benefits among students at 3 months follow-up. For the primary outcome, we will explore moderators including child’s sex, child’s disability status, the green-space of neighbourhoods, the school’s socio-economic position and teacher’s experience.DiscussionIn conducting the first randomized controlled trial of the Open Sky School, our results could provide empirical evidence on the effectiveness of nature-based interventions in reducing mental health problems among elementary school children.Trial registrationThis study was registered with clinicaltrials.gov: NCT05662436 on December 22, 2022.

Alcoholic Consumption and Antisocial Behaviours Among Secondary School Students in Ado Ekiti, Ekiti State

The study examined the influence of alcoholic consumption on the social behaviour problems among secondary school students in Ado, Ekiti State. The study specifically examined if there is any difference between social behaviour of secondary school students that indulge in drinking of alcohol as a habit in Ado. The research design that was adopted for this study is descriptive survey design. The population of the study consisted of all the public secondary school students, both male and female in Ado Ekiti, Ekiti State. The sample of this study consisted of 300 students selected randomly from the public secondary schools in Ado Ekiti State. The method of selection was multi stage sampling procedure which was used to determine the schools, and students used for the study. The first stage involved the selection of five streets out of the twenty streets in Ado Ekiti, Nigeria using simple random sampling technique. The second stage was a simple random sampling technique in the selection of five schools. In the third stage, stratified random sampling technique was used to select classes from each of the school selected which are students from SS1 to SS III. The last stage also involved the use of stratified random sampling technique to select 40 students from each school based on gender of the students. A self-designed research instrument tagged ‘Alcoholism and Students Social Behaviour Questionnaire (ASSBQ) was used to collect relevant data for the study. Section A of the instrument seek for students’ Bio-data while section B contained questions on the influence of alcoholism on the social behaviour of students in Ado-Ekiti which were given to students to respond to. Data collected was analyzed using both descriptive and inferential statistics. The research question was analysed using frequency counts, percentage, mean, and table, while the research hypotheses 1 and 2 were analyzed using t-test, hypothesis 3 was tested using Pearson Product Moment Correlation. All hypotheses were tested at 0.05level of significant. The study revealed that there is significant difference between the social behaviours of students that indulge in alcohol drinking habit and those who do not and that alcohol consumption is significantly related to antisocial behaviours among adolescents in secondary schools. The study recommended among others that school guidance counsellors should create effective techniques to convey pertinent information regarding alcohol drinking, including details about its immediate and long-term impacts. Also, the school administration should encourage initiatives that will provide pupils the social skills they need to withstand peer pressure's influence on alcohol use and, as a result, lessen antisocial behaviour among adolescents. It is also recommended that parent-child relationships should be improved, discipline should be constant, and parents should watch over their kids' activities. This is based on the premise that the likelihood that teenagers will engage in alcohol consumption and participate in antisocial behaviours will decline as family ties are strengthened.

The relationship between three subtypes of safety behaviors and social anxiety: Serial mediating effects of state and trait post-event processing

The cognitive model for social anxiety disorder (SAD) highlights the role of safety behaviors and post-event processing (PEP). We identify the serial mediating effect of state and trait PEP between three types of safety behaviors (impression management, avoidance behavior, and anxiety-symptom control) and social anxiety. Given that the associations between the three subtypes of safety behaviors and two perspectives of PEP have not yet been examined, we aimed to investigate these relationships according to the level of social anxiety. A total of 487 participants participated in an online survey. Participants were classified into two groups, high and low, based on their social anxiety scores. We used Social Behavior Questionnaire to distinguish three types of safety behaviors and the State and Trait versions of the Post-Event Processing Inventory to identify two perspectives of PEP. We used descriptive statistics and an independent t-test to compare the high and low social anxiety groups. Mediation effects were examined using mediation analysis and bootstrapping with 5,000 replications. The results showed that the three safety behaviors had different effects on social anxiety via PEP. In the high social anxiety group, avoidance behavior and anxiety-symptom control predicted social anxiety positively, whereas impression management did not. However, with state PEP and trait PEP as mediators, impression management and avoidance behavior positively predicted social anxiety but not anxiety-symptom control. In the low social anxiety group, only avoidance behavior was significantly related to social anxiety, but when the state and trait PEP were mediated, the effect disappeared. These results indicated that impression management could affect social anxiety only when mediated by PEP in people with high social anxiety. A better understanding of the content and processes underpinning safety behavior and PEPs might have important implications for the prevention and treatment of social anxiety disorder.

Psychometric properties of the Social Behavior Questionnaire (SBQ) in a longitudinal population-based sample

We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5–12 years. Children (n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child Development. Mothers reported the frequency with which children presented social and emotional behaviors from 3.5 to 8 years of age, and teachers from 6 to 12 years. We assessed internal structure using Confirmatory Factor Analysis, reliability using Cronbach’s alpha, and convergent and discriminant validity using a multitrait-multimethod (MTMM) approach. The six-factor (emotional distress, withdrawal, impulsive/hyperactive/inattentive, disruptive behaviors, prosocial behaviors, and peer relationships difficulties) structure of the SBQ showed good fit from ages 3.5 to 12 years. Reliability estimates were good to excellent (alphas > .7), and MTMM showed good convergent and discriminant validity. Overall, the SBQ presented good psychometric properties with a large population-based sample aged 3.5–12 years. Further studies should assess its screening potential by investigating its convergent validity with diagnostic information.

0012 Disordered sleep and emotional self-regulation in a prospective cohort of preschool-age children

Abstract Introduction Disrupted sleep has been associated with poor emotional self-regulation among preschool-age children cross-sectionally, with few studies examining change over time. Our goal was to examine the prospective association between disrupted sleep and emotional self-regulation over six months among preschool-age children. Methods Analyses included 54 children, age 3-5 years old, who completed their participation in a currently ongoing, 6-month prospective study conducted in a rural area of New England to examine early-life predictors of obesity. Parents completed the 35-item Children’s Sleep Habits Questionnaire (CSHQ), a validated scale to measure problematic sleep, reflecting both reduced sleep quantity and quality. Total scores greater than 41 reflect a clinically-meaningful sleep disorder. Parents also completed the 5-item emotional self-regulation subscale of the validated Child Social Behavior questionnaire. A final score was computed as the average across the 5 items (range 1-7), with higher scores indicating poorer emotional self-regulation. A series of linear regression models were used to examine associations between sleep and emotional self-regulation at baseline, as well as change in self-regulation over six months. Each model was adjusted for child age, sex, and parental education level. Results The sample was largely white, non-Hispanic (87.0%), with 61.1% of male children, 90.7% of accompanying parents as mothers, and 79.6% of parents with a Bachelor’s degree or greater. One-fourth (n=14, 25.9%) of children met the criteria for disordered sleep at baseline. In an adjusted linear regression model, children with disordered sleep at baseline, on average, had worse self-regulation at baseline (beta coefficient=0.90, SE=0.33; p&amp;lt;0.01) and, separately, a greater decrease in self-regulation over six months (beta=0.78, SE=0.30; p=0.01). When further adjusting for disordered sleep at month 6, disordered sleep at baseline remained predictive of a greater decrease in self-regulation over time (beta=1.12; SE=0.41; p&amp;lt;0.01). Conclusion In this preliminary analysis, disordered sleep was associated with poor emotional self-regulation cross-sectionally and a decline in emotional self-regulation over six months. Generalizability is limited because of the high socioeconomic status of the sample. Yet findings suggest that the effects of disordered sleep on emotional self-regulation may manifest within in the preschool-years.

Mediating Factors in Within-Person Developmental Cascades of Externalising, Internalising and ADHD Symptoms in Childhood

Previous studies have offered evidence for peer problems and academic achievement as mediators in developmental cascades from externalising to internalising problems, and from ADHD symptoms to both internalising and externalising problems. However, these mediators have not been found to fully account for these cascades, indicating that there may be additional mediators involved. This study investigated the role of harsh parenting and parental involvement alongside academic achievement and peer problems in mediating within-person developmental cascades from externalising to internalising problems and from ADHD symptoms to internalising and externalising problems using autoregressive latent trajectory models with structured residuals. Models were fit for parent- and teacher-reports on children’s psychosocial development as measured by the Social Behaviour Questionnaire (SBQ) collected over ages 7, 9, and 11 in an ethnically diverse Swiss longitudinal cohort study (z-proso; N = 1387, 51% male). Results indicated that, when appropriately disentangling within- from between-person effects, none of the considered factors acted as significant mediators in longitudinal within-person relations between ADHD, internalising and externalising problems; hence, mediating mechanisms in developmental cascades remain to be identified.

Decision-making difficulties mediate the association between poor emotion regulation and eating disorder symptoms in adolescence.

The emergence of eating problems during childhood increases the risk for eating disorders (EDs) during young adulthood. Previous studies highlight a relationship between poor self-regulation and onset of eating pathology. In this study, we investigated whether this association is mediated by decision-making difficulties. To test this hypothesis, we used data from the Millennium Cohort Study. Decision-making performance was assessed with the Cambridge Gambling Task at age 11. Principal components analysis was used to derive an index of ED symptoms at age 14. The trajectories of scores of two subscales of the Child Social Behaviour Questionnaire, Independence and Self-Regulation (ISR) and Emotional Dysregulation (EmotDy), were modelled from ages 3 to 7 years in a latent growth curve analysis. The individual predicted values of the intercept (set at baseline, 3 years) and the slope (rate of annual change) were then used in the mediation analysis. In our sample of 11 303 individuals, there was evidence for mediation by three measures of decision-making at age 11 (poor quality of decision-making, delay aversion and low risk-adjustment) in the association between EmotDy across ages 3-7 and ED symptoms at age 14 even after the adjustment for relevant covariates. We found no evidence of association between ISR and ED symptoms. Our findings suggest that emotion regulation processes during childhood may be relevant for the future onset of ED symptoms via their association with decision-making skills. These findings, obtained from a large, representative, sample, shed light on the relationship between self-regulation, decision-making and symptoms of EDs.

The relationship between ultra-processed food consumption and internalising symptoms among adolescents from São Paulo city, Southeast Brazil.

To investigate the association between ultra-processed food (UPF) consumption and internalising symptoms (IS) among adolescents. It is a cross-sectional study. Paper-pencil survey was completed in classroom with information on UPF consumption, IS and selected covariates. IS were assessed with the Internalizing Symptoms sub-scale from the Social Behaviour Questionnaire (IS-SBQ). UPF was evaluated with a FFQ extracted from the Brazilian National School Health Survey. Crude and adjusted association between UPF and IS was investigated with structural equation models. São Paulo, SP, Brazil. A total of 2680 students, Mage = 14·85; (95 % CI 14·81, 14·88). UPF consumption was associated with higher scores in IS in the crude (β = 0·14; P < 0·001) and adjusted (β = 0·12; P < 0·001) models. The higher the consumption of UPF, the higher is the IS score. The following variables were associated with a lower risk of UPF consumption: male sex, public school and having more meals with parents. The change in the magnitude of the standardised score was almost negligible, but the model was significantly improved with the inclusion of covariates. Our results provide evidence about the positive association between UPF consumption and IS among adolescents. The association, despite its low magnitude, remained significant after adjusting for potential confounders. These results are relevant considering the increase in UPF consumption worldwide and in low- and middle-income countries. Also, our study emphasises the importance of a healthy diet with a reduction in UPF consumption among adolescents.

The role of social support in reducing the impact of violence on adolescents' mental health in São Paulo, Brazil.

ObjectivesWe investigated whether perceived social support among adolescent students moderated the association between violence exposure and internalising symptoms in São Paulo city, Brazil.MethodsWe tested the stress-buffering model using data from the cross-sectional school-based, survey São Paulo Project on the Social Development of Children and Adolescents. Internalising symptoms were measured using an adapted version of the Social Behaviour Questionnaire; serious victimisation, being bullied once/week, school violence and community violence, friend and teacher support were scales adapted by the research team; the Alabama Parenting Questionnaire measured parenting style. Linear mixed-effects models were used to quantify moderation effects of (i) social support between violence exposure and internalising symptoms and (ii) gender between violence exposure and internalising symptoms across schools.ResultsAcross schools, being bullied once/week, school violence, and community violence were associated with a significant (p<0.001) increase in internalising symptoms (e.g., bullied b = 5.76, 95% CI 2.26, 9.26; school violence b = 0.48, 95% CI 0.30, 0.67; community violence b = 0.36; 95% CI 0.22, 0.50). Males exposed to all types of violence had significantly lower (p<0.01) internalising symptoms compared to females (e.g., serious victimisation: b = -1.45; 95% CI -2.60, -0.29; school violence b = -0.27; 95% CI -0.30, -0.24; community violence b = -0.23; 95% CI -0.25, -0.20). As a main effect, social support was associated with a significant (p<0.01) decrease in internalising symptoms across schools (e.g., positive parenting b = -2.42; 95% CI -3.12, -1.72; parent involvement b = -2.75; 95% CI -3.32, -2.17; friend support b = -1.05; 95% CI -1.74, -0.34; teacher support b = -0.90; 95% CI -1.58, -0.22). Social support did not moderate the association between violence exposure and internalising symptoms.ConclusionsAdolescent students in São Paulo exposed to violence have a higher likelihood of internalising symptoms, compared to those who are not. Support from parents, friends, and teachers, independent of violence, appear to be protective against internalising symptoms, pointing to potential programmes that could improve adolescent mental health.

Association of Emotion Regulation Trajectories in Childhood With Anorexia Nervosa and Atypical Anorexia Nervosa in Early Adolescence

People with anorexia nervosa often experience difficulties regulating their emotions. There is no longitudinal evidence as to whether these differences are already present in childhood or when they begin to emerge. To investigate the association between emotion regulation trajectories from 3 to 7 years of age and symptoms of anorexia nervosa and atypical anorexia nervosa in adolescence. This cohort study included all children with complete exposure data in the Millennium Cohort Study, a UK general population birth cohort. Data were acquired from June 2001 to March 2016 and analyzed from June to November 2020. Mothers reported on their children's emotion regulation skills at 3, 5, and 7 years of age using the Children's Social Behavior Questionnaire. Multilevel models were used to derive early childhood emotion regulation scores (ie, predicted intercept) and within-child changes in emotion regulation scores from 3 to 7 years of age (ie, predicted slope). Symptoms consistent with a DSM-5 diagnosis of anorexia nervosa or atypical anorexia nervosa at 14 years of age, defined using a range of questions relative to body image, weight perception, and dieting behaviors (hereinafter referred to as broad anorexia nervosa). Univariable and multivariable logistic regression models tested the association between exposures and outcome. Regression models were adjusted for child and family sociodemographic and socioeconomic characteristics and mental health difficulties, prenatal and perinatal factors, child's cognitive development, and maternal attachment. A total of 15 896 participants (85.7% of total sample; 51.0% boys; 84.5% White individuals) had complete data on the exposure and were included in the main analyses. Among those with complete exposure and outcome data (9912 of the analytical sample [62.4%]), 97 participants (1.0%; 86 [88.7%] girls and 85 [87.6%] White individuals) had symptoms consistent with a diagnosis of broad anorexia nervosa at 14 years of age. No evidence suggested that children with lower emotion regulation ability at 3 years of age had greater odds of later reporting symptoms of broad anorexia nervosa (odds ratio [OR], 1.21; 95% CI, 0.91-1.63). However, children whose emotion regulation skills did not improve over childhood and who had greater problems regulating emotions at 7 years of age had higher odds of having broad anorexia nervosa at 14 years of age (OR, 1.45; 95% CI, 1.16-1.83). These findings suggest that difficulties in developing age-appropriate emotion regulation skills in childhood are associated with experiencing broad anorexia nervosa in adolescence. Interventions to support the development of emotion regulation skills across childhood may help reduce the incidence of anorexia nervosa.

Adrenocortical Activity and Aggressive Behavior in Children: A Longitudinal Study on Risk and Protective Effects.

Most research on aggression and delinquency concentrates on risk factors. There has been less attention for protective factors and mechanisms, in particular with regard to biosocial influences. Based on theories of autonomous arousal and stress reactance the present study addresses the influence of adrenocortical activity as a risk and/or protective factor in the development of antisocial behavior in children. We also investigated relations to anxiousness and family stressors. In a prospective longitudinal study of 150 German boys, the first measurement took place at preschool age and contained an assessment of cortisol after waking up and 30 min later. Aggressiveness and anxiousness of the children were assessed by the kindergarten teachers with the Social Behavior Questionnaire. After 6 years, the children's behavior was rated by the teachers in middle school. Variable-oriented data analyses revealed a significant correlation between the total amount of cortisol after waking up and 30 min later (AUCG) and anxiousness both cross-sectionally and longitudinally, but not with aggressiveness. A family stress index correlated positively with aggressiveness but neither with cortisol nor with anxiousness. There were significant correlations between aggressiveness and anxiousness at kindergarten age and the respective behavior problems 6 years later. In a linear regression analysis on aggression only family stress had a significant effect but anxiousness not. Moderator analyses on aggressiveness with anxiousness and AUCG or on AUCG with anxiousness and aggressiveness did not show any significant interactions. Longitudinally, only aggression significantly predicted aggression 6 years later in a linear regression. In addition to variable-oriented analyses, we also applied a person-oriented approach to investigate specific patterns of behavior. Children who were high in both aggressiveness and anxiousness had the highest cortisol level and those with low anxiousness and high aggressiveness the lowest. The groups with different patterns of externalizing and internalizing problems at preschool age showed significant differences in aggression 6 years later. Our results underline the need for complex pattern analyses on cortisol, aggression, and anxiousness in children and for a differentiated consideration of emotional reactive aggression and unemotional instrumental aggression.

The association between parent-child technology interference and cognitive and social-emotional development in preschool-aged children.

The increased adoption and dependence of electronic devices have potential implications on parent-child relationships, including parental responsiveness. Few studies have examined the association between parent-child technology interference and developmental outcomes. The objective of this study was to examine the associations between parent-child technology interference and cognitive and social-emotional development in preschool-aged children (3-5years). Participants were 100 parents and their preschool-aged child from Edmonton, Canada. Parent-child technology interference across six different devices (i.e., cell phone/smartphone, tablet, iPod, television, computer and video game console) was parental reported using an adapted version of the Technology Device Interference Scale, and a total score was calculated. Cognitive development was objectively measured using three iPad-based tasks from the Early Years Toolbox to capture executive functions (i.e., working memory and response inhibition) and language development (i.e., expressive vocabulary). Social-emotional development was parental reported using the Child Self-Regulation and Social Behaviour Questionnaire, and seven subscales (i.e., sociability, externalizing, internalizing, prosocial and behavioural, cognitive, and emotional self-regulation) were calculated. Multiple linear regression models that adjusted for several potential confounders were conducted. The mean total parent-child technology interference score was 4.2units, which equates to approximately 12-16 interruptions per day due to an electronic device. Approximately 60% of the score was due to interference by a cell phone/smartphone. After removing influential cases based on Cook's distance values, higher parent-child technology interference was significantly associated with lower response inhibition (B = -0.015, 95% CI: -0.028, -0.002) and emotional self-regulation (B = -0.095, 95% CI: -0.163, -0.028) scores and higher log externalizing (B = 0.033, 95% CI: 0.002, 0.063) and log internalizing (B = 0.034, 95% CI: 0.013, 0.056) scores. Electronic devices, in particular the cell phone/smartphone, appear to interrupt parents' conversations and activities with their preschool-aged child multiple times per day. Higher parent-child technology interference may be adversely associated with several subdomains of early childhood development. Future longitudinal and experimental research is needed to confirm these findings.
