We aimed to investigate the relationship between environmental exposure to BPA and childhood neurobehavior. Methods Urinary BPA concentrations and behavioral and learning characteristics were assessed in a general population of 1,089 children, aged 8–11 years. The main outcome measures were the Child Behavior Checklist (CBCL) and the Learning Disability Evaluation Scale (LDES). Results Urinary levels of BPA were positively associated with the CBCL total problems score and negatively associated with the learning quotient from the LDES. The linear association with the CBCL anxiety/depression score and the quadratic association with the LDES listening score were significant after correction for multiple comparisons. Conclusions Environmental exposure to BPA might be associated with childhood behavioral and learning development. The results suggest possible nonmonotonic relationships.

Different clinical courses of children exposed to a single incident of psychological trauma: a 30-month prospective follow-up study / Soon-Beom HONG in Journal of Child Psychology and Psychiatry, 55-11 (November 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-11 (November 2014) . - p.1226-1233 Titre : Different clinical courses of children exposed to a single incident of psychological trauma: a 30-month prospective follow-up study Type de document : Texte imprimé et/ou numérique Auteurs : Soon-Beom HONG, Auteur ; George J.

Methods The cohort was followed-up at 2 days (T1), 2 months (T2), 6 months (T3), and 30 months (T4) after the traumatic event. The children's posttraumatic stress symptoms (T1–T4), depression (T1, T3 and T4), state anxiety (T1, T3 and T4), and quality of life (T4) were assessed, along with parental stress related to child rearing (T4). Different trajectory patterns of the children's posttraumatic stress symptoms were identified using growth mixture modeling (GMM). Results Four different patterns of symptom change were identified, which were consistent with the prototypical model, and were named Recovery (19.9%), Resilience (72.7%), Chronic Dysfunction (1.8%), and Delayed Reactions (5.6%). Significant differences were found in depression and anxiety scores, children's quality of life, and parental rearing stress according to the distinct longitudinal trajectories of posttraumatic stress symptoms. Conclusions The present study suggests that individual differences should be taken into account in the clinical course and outcome of children exposed to psychological trauma. The two most common trajectories were the Resilience and the Recovery types, together suggesting that over 90% of children were evidenced with a favorable 30-month outcome. The latent classes were associated with significant mean differences in depression and anxiety scores, supporting the clinical validity of the distinct trajectories.

Effect of environmental exposure to lead and tobacco smoke on inattentive and hyperactive symptoms and neurocognitive performance in children / Soo-Churl CHO in Journal of Child Psychology and Psychiatry, 51-9 (September 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-9 (September 2010) . - p.1050-1057 Titre : Effect of environmental exposure to lead and tobacco smoke on inattentive and hyperactive symptoms and neurocognitive performance in children Type de document : Texte imprimé et/ou numérique Auteurs : Soo-Churl CHO, Auteur ; Boong-Nyun KIM, Auteur ; Yun-Chul HONG, Auteur ; Min-Sup SHIN, Auteur ; Hee Jeong YOO, Auteur ; Jae-Won KIM, Auteur ; Soo-Young BHANG, Auteur ; In Hee CHO, Auteur ; Hyo-Won KIM, Auteur Année de publication : 2010 Article en page(s) : p.1050-1057 Langues : Anglais (eng) Mots-clés : Attention-deficit-hyperactivity-disorder-(ADHD) cognition environmental-health lead smoking Index. décimale : PER Périodiques Résumé : Background:  The present study assessed the association between blood lead and urinary cotinine levels and inattentive and hyperactive symptoms and neurocognitive performance in children. Methods:  A total of 667 children (age range 8–11) were recruited from nine schools in five Korean cities. The teachers and parents completed the Korean version of the Attention-deficit/hyperactivity disorder Rating Scales (K-ARS), and the children performed neurocognitive tests. Blood lead and urinary cotinine levels were then measured. Results:  The inattentive, hyperactive, and total scores of the teacher-rated K-ARS were positively associated with blood lead level, and the results of the continuous performance test (CPT), Stroop Color–Word Test, and Children’s Color Trails Test were inversely associated with urinary cotinine level when controlled for age, gender, father’s educational level, maternal IQ, child’s IQ, residential area, birth weight, and cotinine (for lead) or lead (for cotinine). The association between blood lead level and commission errors score on the CPT disappeared when the effect of urinary cotinine level was controlled. Conclusions:  These findings indicate that environmental exposure to tobacco smoke in children is associated with poor neurocognitive performance, and low levels of lead are associated with inattention and hyperactivity symptoms.

Increased use of lethal methods and annual increase of suicide rates in Korean adolescents: comparison with adolescents in the United States / Subin PARK in Journal of Child Psychology and Psychiatry, 55-3 (March 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-3 (March 2014) . - p.258-263 Titre : Increased use of lethal methods and annual increase of suicide rates in Korean adolescents: comparison with adolescents in the United States Type de document : Texte imprimé et/ou numérique Auteurs : Subin PARK, Auteur ; Soo-Churl CHO, Auteur ; Bung-Nyun KIM, Auteur ; Jae-Won KIM, Auteur ; Hee Jeong YOO, Auteur ; Jin Pyo HONG, Auteur Article en page(s) : p.258-263 Langues : Anglais (eng) Mots-clés : Adolescence  suicide Index. décimale : PER Périodiques Résumé : Background The lethality of the suicide method is a strong risk factor for completed suicide. We examined whether the annual change in the pattern of suicide methods was related to the annual change in suicide rates among adolescents in South Korea and the United States. Methods We analyzed annual data for the 2000–2009 period for South Korea and the 2000–2008 period for the United States to examine time trends in the suicide rates and suicide methods of adolescents aged 10–19 years in two countries. Data on suicide methods were obtained from the World Health Organization (WHO) mortality database. Results Suicide rates among adolescents in the United States have remained relatively steady since 2000, whereas the suicide among Korean adolescents has increased. Between 2000 and 2009, the most common suicide method among Korean adolescents was jumping for boys and girls, whereas it was hanging for girls and firearms for boys in the United States. Along with the annual increase in suicide rates in South Korea, the incidences of jumping among males and hanging (and recently jumping) among females have increased steadily, whereas suicide by self-poisoning steadily decreased. In the United States, between 2000 and 2008, the proportion of suicides committed by hanging increased, whereas those committed using firearms steadily decreased, particularly among adolescent females. Conclusions These findings suggest that the increased use of lethal suicide methods is reflected in the increase in suicide rates in Korean adolescents. The most fruitful approach to addressing the rises in jumping suicides among Korean adolescents and hanging suicides among adolescents in the United States may be through population-based initiatives to reduce the physical availability (e.g., limiting access to or fencing off tall structures) and the social acceptability (e.g., effective and responsible regulations for reporting suicide) of these methods.

Sex differences in children with autism spectrum disorders compared with their unaffected siblings and typically developing children / Subin PARK in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 6-2 (April-June 2012) . - p.861-870 Titre : Sex differences in children with autism spectrum disorders compared with their unaffected siblings and typically developing children Type de document : Texte imprimé et/ou numérique Auteurs : Subin PARK, Auteur ; Soo-Churl CHO, Auteur ; In Hee CHO, Auteur ; Boong-Nyun KIM, Auteur ; Jae-Won KIM, Auteur ; Min-Sup SHIN, Auteur ; Un-Sun CHUNG, Auteur ; Tae-Won PARK, Auteur ; Jung-Woo SON, Auteur ; Hee Jeong YOO, Auteur Année de publication : 2012 Article en page(s) : p.861-870 Langues : Anglais (eng) Mots-clés : Autism  Sex  Autistic symptoms  Behavior problems  Empathizing  Systemizing Index. décimale : PER Périodiques Résumé : This study examined the nature of cognitive and behavioral sex differences in children with autism spectrum disorders (ASDs) and two comparison groups: a group of typically developing (TD) children and a group of unaffected siblings of ASD children. Sex differences in core autistic symptoms, co-occurring behavioral symptoms, and cognitive styles were assessed in each group. Females with ASD were less severely affected than IQ- and age-matched males with ASD in the communication and repetitive stereotyped behavior domains, as measured by the ADI-R, but such sex differences were less significant than they were in the unaffected sibling group. Several behavioral/emotional symptom scores were significantly higher in male siblings than in female siblings. However, the ASD and TD groups did not show sex differences in any behavioral/emotional symptom scores. Males were superior in systemizing relative to empathizing, while the opposite was true for females in the unaffected sibling group and the TD children group; however, both males and females were superior in systemizing relative to empathizing in the ASD group. Our findings support the extreme male brain theory of autism, and further studies are needed to understand the mechanisms behind and developmental perspectives on the nature of sex differences in ASD.
