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.
