Study of Positive and Negative Affect and Neurocognitive Functioning in Adolescents

The main purpose of the present work was to study neurocognitive performance of adolescents at risk for emotional difficulties. The sample included a total of 1,509 adolescents from stratified random cluster sampling. Derived from this sample, a group of high-risk (n = 92) and a comparison group (n = 92) were selected based on the short version of the Positive and Negative Affect Schedule (PANAS) for comparison on the University of Pennsylvania computerized neuropsychological test battery for children (PENN). A Multivariate analysis of covariance (MANCOVA) was performed taking the scores on the PENN as dependent variables and the two groups derived from the scores of the PANAS (at risk vs. comparison) as a fixed factor. Adolescents at high risk of presenting affectivity problems showed statistically significant differences in several different neurocognitive domains, in accuracy, λ = .820, F(9, 160,000) = 3.913, p < .01, partial η² = .180; speed, λ = .502, F(5, 88,000)= 17.493, p < .01, partial η² = .498; and efficiency, λ = .485, F(4, 89,000) = 23.599, p <.01, partial η² = .515. The high risk group showed lower neurocognitive performance than the comparison group. In addition, a positive statistically significant correlation was found between all the neurocognitive competences (p < .05). Results found in this study reveal that neurocognitive impairments can be shown in adolescents at psychometric high risk for emotional problems before transition to more severe psychological problems.

Predictors of emotional problems in 5-year-old children: an international comparison between two cohorts in Chile and Scotland

Emotional problems in early childhood increase the risk of mental health problems into adolescence and adulthood, but the cross-cultural etiological risk factors are unclear. We examined predictors of emotional problems in preschoolers, using a national cohort of children in Chile and in Scotland. Participants included 1648 children and their families enrolled in the Chilean Encuesta Longitudinal de la Primera Infancia (ELPI) cohort and 3786 children and their families enrolled in the Growing Up in Scotland (GUS) cohort. Data were collected between 2005 and 2012. Information on emotional problems along with social and health determinants were collected via maternal reports. Emotional problems in the clinical range were identified in 10.4% of children from the ELPI cohort and in 3.6% of children from the GUS cohort. The difference between cohorts was statistically significant. Logistic regression revealed that maternal unemployment predicted emotional problems across cohorts. Lower maternal education and living in rural areas predicted higher risk of emotional problems for the ELPI cohort only, whereas having a younger mother, daily parent-child shared activities such as a lower frequency of sharing letters/shapes, and a higher exposure to television predicted higher risk for emotional problems for the GUS cohort. Maternal unemployment as a risk factor across cohorts indicates the importance of shared cross-cultural factors. However, sample specific differences highlight the importance and need for greater attention towards cultural specificities in policy and intervention development for child mental health.

Prenatal exposure to environmental contaminants and behavioural problems at age 7–8 years

Animal studies showed that the developing brain is particularly sensitive to chemical exposure. Human studies carried out in areas with high exposures have proven neurodevelopmental disorders in relation to e.g. lead and PCBs. Whether these chemicals are associated with behavioural problems in childhood at current environmental levels is not well known. Therefore, we assessed the association between prenatal exposure to lead, cadmium, PCBs, dioxin-like compounds, HCB and p,p′-DDE and behavioural problems in 7–8year old children. Prenatal exposure data were obtained from the Flemish mother–new-born cohort. Lead, cadmium, PCBs, dioxin-like compounds, HCB and p,p′-DDE were analysed in cord blood. When the child reached 7–8years, 270 mothers completed the Strengths and Difficulties Questionnaire assessing their children's behavioural health. We found that doubling the prenatal lead exposure (cord blood lead levels) was associated with a 3.43 times higher risk for hyperactivity in both boys and girls. In addition, total difficulties were 5.08 times more likely in the highest tertile for prenatal lead exposure compared to the lowest tertile. In girls, total difficulties were 4.92 more likely when doubling cord blood p,p′-DDE, whereas no significant association was found in boys. Further, we noted in boys a 1.53 times higher risk for emotional problems when doubling cord blood cadmium, whereas no significant association was found in girls. These results indicate that the presence of environmental contaminants influences the mental health of the next generation.

Maternal folate status in early pregnancy and child emotional and behavioral problems: the Generation R Study

Maternal prenatal folate status has been linked to neurodevelopmental disorders, but the association with child emotional and behavioral problems is unclear. We assessed the association of maternal folate status during pregnancy with child emotional and behavioral problems. Also, we examined whether any association between folate status and child problems is a consequence of maternal folic acid supplement use or variation in maternal MTHFR genotype. Within a population-based cohort, we measured maternal plasma folate concentrations in early pregnancy and assessed folic acid supplement use by questionnaire. Mothers of European descent were genotyped for the MTHFR 677 C→T polymorphism. Child emotional and behavioral problems were assessed with the Child Behavior Checklist at 3 y in 3209 children. Children of mothers with prenatal folate deficiency were at higher risk of emotional problems (OR: 1.57; 95% CI: 1.03, 2.38) but not behavioral problems (OR: 1.00; 95% CI: 0.64, 1.56) after adjustment for confounders. A higher risk of emotional problems was also found in children whose mothers started using folic acid supplements late or did not use supplements at all (OR: 1.45; 95% CI: 1.14, 1.84) than in children whose mothers started periconceptionally. However, low plasma folate concentrations only partly explained this association (OR: 1.38; 95% CI: 1.08, 1.78). Although related to plasma folate concentrations, maternal MTHFR genotype did not explain the association of folate status with offspring emotional problems. Low maternal folate status during early pregnancy is associated with a higher risk of emotional problems in the offspring.

Psychosocial health in children and adolescents surviving cancer

To explore psychosocial health in children and adolescents surviving cancer three years after diagnosis compared with healthy controls, as assessed by adolescents themselves, their parents and teacher. Case-control study included 50 children and adolescents diagnosed with cancer between 1 January 1993 and 1 January 2003 and treated at the Paediatric Department St. Olav's University Hospital, Trondheim, Norway. Data were collected using the Strengths and Difficulties Questionnaire (self-report, parent report and teacher report), as well as the Achenbach System of Empirically Based Assessment questionnaire (teacher report). Children surviving cancer had more emotional symptoms, higher total problem scores and poorer academic performance than their peers. Emotional problems were consistently reported by parents, teachers and adolescents themselves, in particular in children with brain tumours and among survivors with late effects. Our study shows that children surviving cancer are at higher risk for emotional problems when compared with their friends, even after several years following diagnosis and treatment. We conclude that when planning long-term follow-up care, rehabilitation of children and adolescents with cancer, especially for survivors with brain tumours and late effects, should particularly take into account their psychological problems and psychosocial functioning.

Regional effects on the mental health of immigrant children: Results from the New Canadian Children and Youth Study (NCCYS)

Children in immigrant families from Hong Kong, Mainland China, and the Philippines living in Toronto and Montreal are at higher risk of Emotional Problems than children in immigrant families in Winnipeg, Calgary, Edmonton, and Vancouver ( Beiser et al., 2010). The current publication explores human capital, social capital, institutional receptivity, and perceptions of welcome as explanations for regional disparities. Parent's lack of linguistic fluency, and depressive symptoms provided the most likely explanation for Montreal's mental health disadvantage. Immigrant human and social capital, poor home-school relationships, marginalization, and lack of neighborhood organization contributed to the prediction of risk for emotional problems among immigrant children in Toronto, but may not fully account for differences between Toronto and Vancouver.

The impact of perinatal and socioeconomic factors on mental health problems of children from a poor Brazilian city: a longitudinal study

Low birth weight and preterm birth, and social disadvantage may negatively affect mental health of children, but findings have been inconsistent. To assess the influence of perinatal and social factors on mental health problems in children aged 7-9 years. A random sample of 805 births in São Luís, Brazil was studied in 1997/1998 and again in 2005/2006. Perinatal, socioeconomic and demographic variables were assessed within 24 h after delivery. The Strengths and Difficulties Questionnaire (SDQ) was used to assess mental health problems in the children. Simple and multiple Poisson regressions were used for statistical analysis. The overall prevalence of mental health problems in the total sample was 47.7%. The prevalences of emotional and conduct problems were 58.2 and 48.8%, respectively. Only paternal age (<20 years) was associated with mental health problems as measured by the full SDQ scale (prevalence ratio PR = 1.27). Children born to single mothers (PR = 1.31) and those with birth weight from 1,500 to 2,499 g (PR = 1.18) and from 2,500 to 2,999 g (PR = 1.17) had a higher risk of emotional problems, but those from low income families had a lower risk (PR = 0.80). Children with a father of less than 20 years had a higher risk of having problems with their peers (PR = 1.75). A maternal education of 9 years or over was inversely associated with peer (PR = 0.70) and conduct problems (PR = 0.73). Girls had a lower risk of conduct (PR = 0.77) and hyperactivity problems (PR = 0.68). A maternal education of 4 years or less increased the risk of hyperactivity (PR = 1.48). Socioeconomic and demographic conditions were better predictors of mental health problems in children than birth weight or preterm birth. However, since most effect sizes were small most mental health problems were, unexplained by the variables in the study.
