JOHNSON, Auteur Article en page(s) : p.36 Langues : Anglais (eng) Mots-clés : Cognitive functioning  Early adversity  Growth hormone system  International adoption  Physical growth Index. décimale : PER Périodiques Résumé : BACKGROUND: Internationally adopted children have often experienced early adversity and growth suppression as a consequence of institutional care. Furthermore, these children are at risk for impaired cognitive development due to their early adverse experiences. This study examined the association between physical growth, the growth hormone (GH) system, and general cognitive functioning post-adoption. Based on previous research, we expected to find that a child's initial physical growth status and normalization of the growth hormone-insulin-like growth factor 1 (GH-IGF-1) axis would be positive predictors of general cognitive functioning. METHODS: Post-institutionalized children (n = 46) adopted from Eastern Europe were seen approximately 1 month after their arrival into the USA to determine baseline measurements. They were seen again 6 and 30 months later for two follow-up sessions. Measures included anthropometry, insulin-like growth factor-1 (IGF-1), IGF binding protein-3 (IGFBP-3), Mullen Scales of Early Learning, and Stanford-Binet Intelligence Scales. Information about parental education was also collected. RESULTS: We found that a child's general cognitive functioning at 30 months post-adoption was predicted by their general developmental scores at 6 months post-adoption, their initial height status, and markers of the growth hormone system. Children with lower initial IGFBP-3 standard deviation (SD) scores had higher verbal IQ scores at 30 months. Furthermore, a child's initial height was found to be a significant positive predictor of non-verbal IQ. CONCLUSIONS: These results suggest an association between a child's suppressed physical growth in response to early adversity and alterations in GH system functioning and subsequent recovery in cognitive functioning.

The caregiving context in institution-reared and family-reared infants and toddlers in Romania / Anna T. SMYKE in Journal of Child Psychology and Psychiatry, 48-2 (February 2007)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 48-2 (February 2007) . - p.210–218 Titre : The caregiving context in institution-reared and family-reared infants and toddlers in Romania Type de document : texte imprimé Auteurs : Anna T. SMYKE, Auteur ; Nathan A. FOX, Auteur ; Sebastian F. KOGA, Auteur ; Dana E. JOHNSON, Auteur ; Peter J. MARSHALL, Auteur ; Charles H. ZEANAH, Auteur ; BEIP CORE GROUP, Auteur ; Charles A. NELSON, Auteur Année de publication : 2007 Article en page(s) : p.210–218 Langues : Anglais (eng) Mots-clés : Infancy orphans institutionalization caregiving-quality cognitive-deficits physical-growth emotional-expression competence Index. décimale : PER Périodiques Résumé : We assess individual differences in the caregiving environments of young children being raised in institutions in Romania in relation to developmental characteristics such as physical growth, cognitive development, emotional expression, and problem and competence behaviors. Method: Videotaped observations of the child and favorite caregiver in their 'home' environment were coded for caregiving quality, and this was related to child characteristics. Child emotional reactivity was assessed during responses to interactional tasks. Cognitive development was assessed from child responses to the Bayley Scales of Infant Development. Data regarding problem behaviors and competence were obtained from caregiver report. Children reared in institutions were compared on all of these measures to never institutionalized children to assist gauging degree of impairment. Results: Children raised in institutions demonstrated marked delays in cognitive development, poorer physical growth, and marked deficits in competence. Individual differences in caregiving environment were associated with cognitive development, competence, and negative behavior among these young children being reared in institutions. Conclusions: These data confirm previous findings regarding deficits associated with institutional care and extend our understanding of the impact of individual differences in caregiving quality on the development of young children in institutions.
