Two vignette studies were conducted in which preadolescent children (Study 1: N=542; Study 2: N=137; aged 8-13years) evaluated the exclusion, for unknown reasons, of an immigrant minority child by a native majority peer (majority interethnic exclusion). Study 1 compared children's evaluations of majority interethnic exclusion with their evaluations of (majority and minority) intraethnic exclusion and minority interethnic exclusion, and Study 2 examined children's underlying explanations. Each study compared ethnic majority and ethnic minority respondents and examined the role of in-group bias for the former...

AIMS: Little is known about the adaptation of the right ventricle (RV) to endurance exercise in children. The aim of this study was to assess the effects of 5months of intensive training on RV morphology and function in preadolescent endurance athletes. METHODS: Ninety-four children were evaluated in this study. Fifty-seven male competitive swimmers (aged 10.8±0.2years) were evaluated before (baseline) and after 5months of the training (peak-training), and compared to 37 age- and sex-matched non-athlete children evaluated at baseline and after 5months of natural growth...

Aerobic fitness has previously been related to cognitive control in preadolescents; however, these investigations have generally relied on global measures of performance. Thus, we have little understanding of how aerobic fitness may relate to trial-by-trial modulations in cognitive control. This study utilized congruency sequence effects (CSEs), which characterize how behavior on the current trial is influenced by the previous trial, to investigate the relation of aerobic fitness on varying levels of cognitive control...

Research supports the clinical importance of childhood irritability, as well as its developmental implications for later anxiety and depression. Appropriate treatment may prevent this progression; however, little evidence exists to guide clinician decision making regarding treatment for chronic irritability symptoms. Given the empirical support for irritability as a dimension of oppositional defiant disorder (ODD), behavioral interventions that improve ODD symptoms, especially through emotion regulation training, are strong candidates for identifying effective treatment strategies for irritability...

The dual systems model of adolescent risk-taking portrays the period as one characterized by a combination of heightened sensation seeking and still-maturing self-regulation, but most tests of this model have been conducted in the United States or Western Europe. In the present study, these propositions are tested in an international sample of more than 5000 individuals between ages 10 and 30 years from 11 countries in Africa, Asia, Europe and the Americas, using a multi-method test battery that includes both self-report and performance-based measures of both constructs...

Child temperament as well as parenting behaviors have been linked to adolescent depression. Beyond their main effects, the interplay between these factors is of interest. For example, in an interactive model, a differential susceptibility of temperamental variants to parenting has been suggested. However, so far, the differential susceptibility hypothesis has mostly been studied with a focus on externalizing disorders. On the other hand, parenting may shape the child's temperament and vice versa in a transactional process...

Solitary fibrous tumors of the spine are rare lesions. Their description in the literature is limited to case reports and small case series. While generally benign lesions, they can recur and occasionally occur as malignancies. Here the authors present the case of a 10-year-old boy, the youngest patient and first preadolescent reported thus far, with this condition. In addition, they perform a comprehensive review of all previously published cases of spinal solitary fibrous tumors.

This study examined the social-cognitive reasoning of 52 Chinese Malaysian preadolescents (9-12 years old; M = 11.02, SD = 0.94) and 68 adolescents (13-18 years old; M = 14.76, SD = 1.39) in resolving filial dilemmas within the personal and moral domain. Preadolescents deferred to parental authority, whereas adolescents endorsed filial obligation reasoning to justify compliance in the personal domain. Both appealed to filial obligation, pragmatic, or welfare and safety reasoning to justify compliance but fairness or rights reasoning to justify their noncompliance, for the moral issue...

BACKGROUND AND AIMS: Substance use during adolescence can lead to the development of substance use disorders and other psychosocial problems. These negative outcomes are especially likely for individuals who use substances at earlier ages and those who engage in heavier use during adolescence, behaviors which are both more common among youth at higher risk for developing a substance use disorder, such as those with a family history of substance use disorders (FH+). Factors such as increased sensation seeking and greater exposure to stressors among FH+ youth may influence these associations...

BACKGROUND: Fetal growth restriction (FGR) affects 5% to 10% of newborns and is associated with increased cardiovascular mortality in adulthood. We evaluated whether prenatal cardiovascular changes previously demonstrated in FGR persist into preadolescence. METHODS AND RESULTS: A cohort study of 58 FGR (defined as birth weight below 10th centile) and 94 normally grown fetuses identified in utero and followed-up into preadolescence (8-12 years of age) by echocardiography and 3-dimensional shape computational analysis...

The mechanisms by which early chronic low-level lead (Pb) exposure disrupts the developing brain are not yet understood. Rodent models have provided promising results however behavioral tests sensitive to effects at lowest levels of exposure during development are needed. Preadolescent animals (N=52) exposed to low and higher levels of Pb via lactation from birth to PND 28 completed the Object-in-Place Task of visual spatial and visual object memory retrieval (at PND 28). Generalized linear mixed models were used, controlling for sex and litter as a random effect...

OBJECTIVE: There is increasing recognition that socio-cognitive skills, such as moral reasoning (MR), are affected in a wide range of developmental and neuropsychological conditions. However, the lack of appropriate measures available to neuropsychologists poses a challenge for the direct assessment of these skills. This study sought to explore age-related changes in MR using an innovative visual tool and examine the developmental sensitivity of the task. METHOD: To address some of the methodological limitations of traditional measures of MR, a novel, visual task, the Socio-Moral Reasoning Aptitude Level (So-Moral), was used to evaluate MR in 216 healthy participants aged 6-20 years...

Diabetes mellitus increasingly afflicts our aging and dysmetabolic population. Type 2 diabetes mellitus and the antecedent metabolic syndrome represent the vast majority of the disease burden-increasingly prevalent in children and older adults. However, type 1 diabetes mellitus is also advancing in preadolescent children. As such, a crushing wave of cardiometabolic disease burden now faces our society. Arteriosclerotic calcification is increased in metabolic syndrome, type 2 diabetes mellitus, and type 1 diabetes mellitus-impairing conduit vessel compliance and function, thereby increasing the risk for dementia, stroke, heart attack, limb ischemia, renal insufficiency, and lower extremity amputation...

Training-induced electrocardiographic changes are common in adult athletes. However, a few data are available on electrocardiogram (ECG) in preadolescent athletes and little is known about the potential changes induced by training on 12-lead electrocardiogram (ECG) at rest. Twelve-lead ECGs at rest and complete echocardiographic examinations were performed in 94 children (57 endurance athletes, 37 sedentary controls; mean age 10.8 ± 0.2 and 10.2 ± 0.2 years, respectively) at baseline and after 5 months of growth and training in athletes and of natural growth in controls...

AIMS: Many men endure immunosuppressive or anticancer treatments that contain alkylating agents prior to the age of sexual maturity, especially the increasing number of preadolescent males who undergo busulfan treatment for myeloablative conditioning prior to hematopoietic stem cell transplantation. Prior to sperm production, there are no sperm available for cryopreservation. Thus, it is necessary to identify a solution to ameliorate the busulfan-induced damage of spermatogonial stem cells (SSCs)...

The present study investigated whether, and to what extent, reflective functioning (RF) during preadolescence is associated with maternal attachment security and RF, and with the child's attachment security. Thirty-nine mother-preadolescent child dyads from a non-clinical population participated in the study. Maternal and child RF were assessed by applying the Reflective Functioning Scale to the Adult Attachment Interview (AAI) and to the Child Attachment Interview transcripts. Children of mothers who showed a secure attachment model regarding the relationship with their parents during childhood reported higher levels of RF than the children of mothers who were classified as insecure on the AAI...
