Not in education, employment and training: pathways from toddler difficult temperament

Beyond the mind: Understanding the influence of mental health on youth NEET status in Europe-A systematic literature review

INTRODUCTION

In the fields of labor market and education research, there is a vast interest in mental health factors affecting unsuccessful school-to-work transitions, dropout from school and labor market disconnections for young people. Young people who are not in employment, education or training are conceived of as NEET.

AIM

To get an overview we conducted a systematic review of the present literature on the influence of mental health on the likelihood of becoming NEET in Europe.

METHOD

A Systematic literature search was conducted in four databases on February 21, 2023, with an update on January 15, 2024.

RESULTS

33,314 articles were screened whereas 41 studies involving 8,914,123 individuals were included. Poor mental health such as attention deficit hyperactive disorder, autism, depression, borderline, and psychosis during childhood and adolescence is strongly associated with becoming NEET.

CONCLUSION

Mental health issues, whether mild or severe, heighten significant the risk of adverse education and employment outcomes in early adulthood, extending to young individuals with personality disorders, borderline personality disorder, and psychoses. These observations inform early intervention strategies for children and young people grappling with mental health challenges. Timely treatment is essential. Future research should focus on the gap in research like specific disorders such as eating disorders and anxiety.

Specialized and versatile antisocial behavioral profiles in preschoolers: Associations with persistent behavioral problems

This study investigated specialized and versatile antisocial patterns in preschoolers and examined the link between these patterns and the risk of developing chronic antisocial behaviors throughout childhood. A total of 556 children (50.6% boys, 88% White) participated in this three-wave longitudinal study at 3-5, 6-8, and 10-12 years old. A latent transition analysis revealed that most preschoolers (89.5%) who adopt several subtypes of antisocial behaviors simultaneously exhibit stable and severe antisocial behaviors throughout childhood. In contrast, most preschoolers (60%) who favor one specific subtype of antisocial behaviors desist from such behaviors between preschool and preadolescence. Importantly, aggression accompanied by other subtypes of antisocial behaviors predicted chronicity better than aggression alone, casting doubt on the notion that aggression is the strongest predictor of chronicity.

Difficult Toddler Temperament - Prevalence and Associated Factors at 18-Month Follow-Up of a Birth Cohort

Purpose

Difficult temperament coupled with other risk factors may lead to mental health problems in childhood and have long-lasting effects in adolescence and adulthood. This study aimed to investigate the prevalence of parental perception of difficult temperament in toddlers and identify significant factors associated with individual and family-level sociodemographic risk factors.

Patients and Methods

The prevalence of parental perception of difficult temperament was derived from items in the 18-month follow-up questionnaire within the Watch Me Grow (WMG) longitudinal birth cohort study in a multicultural and socioeconomically disadvantaged community in Sydney, Australia. Data was available for 500 children and their parents. Descriptive analysis was used to calculate the participant characteristics and the prevalence of parental perception of difficult temperament, whereas multivariable logistic regression analysis was used to assess significant risk factors associated with a difficult temperament.

Results

Parental perception of difficult temperament in the cohort was 7.3% (n = 492). Findings of the multivariable logistic regression showed that screen time >2 hours a day (AOR 2.43, 95% CI: 1.2, 4.9), child not being read to (AOR 3.92, 95% CI: 1.8, 8.5), and family history of mental health problems (AOR 2.69, 95% CI: 1.1, 6.5) significantly increased the odds of having a difficult temperament.

Conclusion

Toddlers with difficult temperament were less likely to have received stimulatory experiences, and their families were more likely to be under greater stress. The findings emphasize the importance of parental support and anticipatory guidance in promoting nurturing care to facilitate child health and development, particularly in disadvantaged communities.

Mechanisms and pathways linking kindergarten behavior problems with mid-life employment earnings for males from low-income neighborhoods

Childhood behavior problems are associated with reduced labor market participation and lower earnings in adulthood, but little is known about the pathways and mechanisms that explain these associations. Drawing on a 33-year prospective birth cohort of White males from low-income backgrounds (n = 1040), we conducted a path analysis linking participants' teacher-rated behavior problems at age 6 years-that is, inattention, hyperactivity, aggression-opposition, and low prosociality-to employment earnings at age 35-39 years obtained from tax records. We examined three psychosocial mediators at age 11-12 years (academic, behavioral, social) and two mediators at age 25 years (non-high school graduation, criminal convictions). Our findings support the notion that multiple psychosocial pathways-especially low education attainment-link kindergarten behavior problems to lower employment earnings decades later.

Does the apple fall far from the tree? Commentary on Hafeman et al., early indicators of bipolar risk in preschool offspring of parents with bipolar disorder

Comorbid externalizing and internalizing disorders are common in offspring of a parent with bipolar I or II disorder. In some cases, the symptoms are harbingers of future bipolar spectrum disorder. Even when they are not, they are likely to be impairing to the child. Clinicians need to be better informed about how the history leading up to mania/hypomania unfolds, and what comorbid disorders are impairing in and of themselves. More information is needed about the parents' psychopathology, course of illness and response to treatment. Until we have data on how to prevent bipolar disorder, the best course of action is to treat the child's current impairing symptoms and render the parent as asymptomatic as possible.

Targeted proteomics identifies potential biomarkers of dysglycaemia, beta cell function and insulin sensitivity in Black African men and women

AIMS/HYPOTHESIS

Using a targeted proteomics approach, we aimed to identify and validate circulating proteins associated with impaired glucose metabolism (IGM) and type 2 diabetes in a Black South African cohort. In addition, we assessed sex-specific associations between the validated proteins and pathophysiological pathways of type 2 diabetes.

METHODS

This cross-sectional study included Black South African men (n=380) and women (n=375) who were part of the Middle-Aged Soweto Cohort (MASC). Dual-energy x-ray absorptiometry was used to determine fat mass and visceral adipose tissue, and fasting venous blood samples were collected for analysis of glucose, insulin and C-peptide and for targeted proteomics, measuring a total of 184 pre-selected protein biomarkers. An OGTT was performed on participants without diabetes, and peripheral insulin sensitivity (Matsuda index), HOMA-IR, basal insulin clearance, insulin secretion (C-peptide index) and beta cell function (disposition index) were estimated. Participants were classified as having normal glucose tolerance (NGT; n=546), IGM (n=116) or type 2 diabetes (n=93). Proteins associated with dysglycaemia (IGM or type 2 diabetes) in the MASC were validated in the Swedish EpiHealth cohort (NGT, n=1706; impaired fasting glucose, n=550; type 2 diabetes, n=210).

RESULTS

We identified 73 proteins associated with dysglycaemia in the MASC, of which 34 were validated in the EpiHealth cohort. Among these validated proteins, 11 were associated with various measures of insulin dynamics, with the largest number of proteins being associated with HOMA-IR. In sex-specific analyses, IGF-binding protein 2 (IGFBP2) was associated with lower HOMA-IR in women (coefficient -0.35; 95% CI -0.44, -0.25) and men (coefficient -0.09; 95% CI -0.15, -0.03). Metalloproteinase inhibitor 4 (TIMP4) was associated with higher insulin secretion (coefficient 0.05; 95% CI 0.001, 0.11; p for interaction=0.025) and beta cell function (coefficient 0.06; 95% CI 0.02, 0.09; p for interaction=0.013) in women only. In contrast, a stronger positive association between IGFBP2 and insulin sensitivity determined using an OGTT (coefficient 0.38; 95% CI 0.27, 0.49) was observed in men (p for interaction=0.004). A posteriori analysis showed that the associations between TIMP4 and insulin dynamics were not mediated by adiposity. In contrast, most of the associations between IGFBP2 and insulin dynamics, except for insulin secretion, were mediated by either fat mass index or visceral adipose tissue in men and women. Fat mass index was the strongest mediator between IGFBP2 and insulin sensitivity (total effect mediated 40.7%; 95% CI 37.0, 43.6) and IGFBP2 and HOMA-IR (total effect mediated 39.1%; 95% CI 31.1, 43.5) in men.

CONCLUSIONS/INTERPRETATION

We validated 34 proteins that were associated with type 2 diabetes, of which 11 were associated with measures of type 2 diabetes pathophysiology such as peripheral insulin sensitivity and beta cell function. This study highlights biomarkers that are similar between cohorts of different ancestry, with different lifestyles and sociodemographic profiles. The African-specific biomarkers identified require validation in African cohorts to identify risk markers and increase our understanding of the pathophysiology of type 2 diabetes in African populations.
