Allostasis and allostatic load in the context of poverty in early childhood / Clancy BLAIR in Development and Psychopathology, 23-3 (August 2011)

HIBEL, Auteur ; THE FAMILY LIFE PROJECT KEY INVESTIGATORS, Auteur Année de publication : 2011 Article en page(s) : p.845-857 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This paper examined the relation of early environmental adversity associated with poverty to child resting or basal level of cortisol in a prospective longitudinal sample of 1135 children seen at 7, 15, 24, 35, and 48 months of age. We found main effects for poor housing quality, African American ethnicity, and low positive caregiving behavior in which each was uniquely associated with an overall higher level of cortisol from age 7 to 48 months. We also found that two aspects of the early environment in the context of poverty, adult exits from the home and perceived economic insufficiency, were related to salivary cortisol in a time-dependent manner. The effect for the first of these, exits from the home, was consistent with the principle of allostatic load in which the effects of adversity on stress physiology accumulate over time. The effect for perceived economic insufficiency was one in which insufficiency was associated with higher levels of cortisol in infancy but with a typical but steeper decline in cortisol with age at subsequent time points.

Association between environmental tobacco smoke exposure across the first four years of life and manifestation of externalizing behavior problems in school-aged children / Lisa GATZKE-KOPP in Journal of Child Psychology and Psychiatry, 61-11 (November 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-11 (November 2020) . - p.1243-1252 Titre : Association between environmental tobacco smoke exposure across the first four years of life and manifestation of externalizing behavior problems in school-aged children Type de document : texte imprimé Auteurs : Lisa GATZKE-KOPP, Auteur ; Michael T. WILLOUGHBY, Auteur ; Siri WARKENTIEN, Auteur ; Daniel PETRIE, Auteur ; W. Roger MILLS-KOONCE, Auteur ; Clancy BLAIR, Auteur Article en page(s) : p.1243-1252 Langues : Anglais (eng) Mots-clés : Disruptive behavior  dopamine  environmental exposures  externalizing disorder  tobacco exposure Index. décimale : PER Périodiques Résumé : BACKGROUND: Extensive literature in human and animal models has documented an association between maternal smoking during pregnancy and externalizing behavior in offspring. It remains unclear; however, the extent to which postnatal environmental smoke exposure is associated with behavioral development, particularly for children whose mothers did not smoke during pregnancy. The present study examined whether magnitude of exposure to environmental smoke across the first four years of life demonstrated a linear association with later externalizing symptoms. METHODS: Exposure was quantified through salivary cotinine measured when children were 6, 15, 24, and 48 months of age, providing a more accurate quantification of realized exposure than can be estimated from parental report of cigarettes smoked. Data were available for n = 1,096 (50% male; 44% African American) children recruited for the Family Life Project, a study of child development in areas of rural poverty. RESULTS: Analyses indicate a linear association between cotinine and children's symptoms of hyperactivity and conduct problems. This association remained significant after controlling for family poverty level, parental education, parental history of ADHD, hostility, depression, caregiver IQ, and obstetric complications. Furthermore, this association was unchanged when excluding mothers who smoked during pregnancy from the model. CONCLUSIONS: Findings are consistent with animal models demonstrating an effect of environmental exposure to nicotine on ongoing brain development in regions related to hyperactivity and impulsivity, and highlight the importance of mitigating children's exposure to environmental smoke, including sources that extend beyond the parents.

Bidirectional genetic and environmental influences on mother and child behavior: The family system as the unit of analyses / W. Roger MILLS-KOONCE in Development and Psychopathology, 19-4 (Fall 2007)

PROPPER, Auteur ; Jean-Louis GARIEPY, Auteur ; Clancy BLAIR, Auteur ; Patricia GARRETT-PETERS, Auteur Année de publication : 2007 Article en page(s) : p.1073-1087 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Family systems theory proposes that an individual's functioning depends on interactive processes within the self and within the context of dyadic family subsystems. Previous research on these processes has focused largely on behavioral, cognitive, and psychophysiological properties of the individual and the dyad. The goals of this study were to explore genetic and environmental interactions within the family system by examining how the dopamine receptor D2 gene (DRD2) A1+ polymorphism in mothers and children relates to maternal sensitivity, how maternal and child characteristics might mediate those effects, and whether maternal sensitivity moderates the association between DRD2 A1+ and child affective problems. Evidence is found for an evocative effect of child polymorphism on parenting behavior, and for a moderating effect of child polymorphism on the association between maternal sensitivity and later child affective problems. Findings are discussed from a family systems perspective, highlighting the role of the family as a context for gene expression in both mothers and children.

Early life predictors of attention deficit/hyperactivity disorder symptomatology profiles from early through middle childhood / Michael T. WILLOUGHBY in Development and Psychopathology, 32-3 (August 2020)

Risk factors that were measured across the first 3 years of life were used to predict profile membership. Participants included 1,173 children who were drawn from the Family Life Project, an ongoing longitudinal study of children's development in low-income, nonmetropolitan communities. Four heuristic profiles of ADHD risk were identified. Approximately two thirds of children never exhibited elevated risk for ADHD. The remaining children were characterized by early childhood onset and persistent risk (5%), early childhood limited risk (10%), and middle childhood onset risk (19%). Pregnancy and delivery complications and harsh-intrusive caregiving behaviors operated as general risk for all ADHD profiles. Parental history of ADHD was uniquely predictive of early onset and persistent ADHD risk, and low primary caregiver education was uniquely predictive of early childhood limited ADHD risk. Results are discussed with respect to how changes to the age of onset criterion for ADHD in DSM5 may affect etiological research and the need for developmental models of ADHD that inform ADHD symptom persistence and desistance.

Evocative gene–parenting correlations and academic performance at first grade: An exploratory study / Cathi B. PROPPER in Development and Psychopathology, 24-4 (November 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-4 (November 2012) . - p.1265-1282 Titre : Evocative gene–parenting correlations and academic performance at first grade: An exploratory study Type de document : texte imprimé Auteurs : Cathi B. PROPPER, Auteur ; Michael J. SHANAHAN, Auteur ; Rosemary RUSSO, Auteur ; W. Roger MILLS-KOONCE, Auteur Année de publication : 2012 Article en page(s) : p.1265-1282 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Academic performance during the first years of school lays the groundwork for subsequent trajectories of academic success throughout childhood and adolescence. The current study tests a model according to which a gene–parenting correlation in the first 3 years of life is associated with subsequent psychosocial adjustment and then academic performance in the first grade (as indicated by teachers' assessment of academic behavior and two subscales of the Woodcock–Johnson Test of Achievement, Third Edition). Drawing on multiple waves of data from the Durham Child Health and Development Study, we find that risk alleles for dopamine receptor genes (dopamine receptor D4 for girls, dopamine receptor D2 for boys) are associated with less sensitive parenting. For girls, parenting mediates the link between dopamine receptor D4 and all academic outcomes. There is some indication that parenting also influences girls' withdrawn behavior in the classroom, which in turn influences teachers' assessments of academic performance. For boys, some evidence suggests that parenting is associated with emotion regulation, which is associated with teachers' assessments of academic behavior and both subscales of the Woodcock–Johnson. Replications of this exploratory study are necessary, but these findings provide a first step in understanding how evocative correlations in the home may predict indicators of psychosocial adjustment that in turn influence performance and achievement at school.
