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.

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.

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.

Sleep problems and their correlates and comorbid psychopathology of children with autism spectrum disorders / Subin PARK in Research in Autism Spectrum Disorders, 6-3 (July-September 2012)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 6-3 (July-September 2012) . - p.1068-1072 Titre : Sleep problems and their correlates and comorbid psychopathology of children with autism spectrum disorders 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.1068-1072 Langues : Anglais (eng) Mots-clés : Autism  Sleep  Behavior problems Index. décimale : PER Périodiques Résumé : This study examined sleep problems and their correlates and comorbid psychopathology in children with autism spectrum disorders (ASDs). Participants consisted of 166 ASD children and 111 unaffected siblings aged 4–15 years. Parents completed a self-administered child sleep questionnaire. Of the children with ASDs, 47.0% (78/166) had at least one sleep problem. Children with ASDs were more likely to have bedtime resistance (OR 2.72, 95% CI 1.02–7.21), insomnia (OR 4.07, 95% CI 1.60–10.35), and daytime sleepiness (OR 7.62, 95% CI 1.17–49.38) compared to their unaffected siblings. Among children with ASDs, multivariate logistic regression analyses indicated that communication abnormalities and repetitive stereotyped behaviors were associated with increased risk of sleep problems. ASD children with sleep problems were more likely to have withdrawal problems, somatizing problems, aggressive behaviors, internalizing problems, externalizing problems, and total behavioral problems compared to those without sleep problems. Sleep problems are prevalent in children with ASDs and are associated with both internalizing and externalizing problems. Clinicians should pay close attention to sleep problems when assessing and treating autistic behaviors.
