However, the link between maternal mood entropy and children’s structural brain development, and how this association may change across childhood, remains unclear. In a longitudinal study with neuroimaging data collected at ages 4.5, 6, 7.5, and 10.5 years (n = 1,498; n = 674 with neuroimaging), we examined whether maternal mood entropy is associated with children’s hippocampal and amygdala volumes over time. Mothers reported on negative mood symptoms at several assessments between ages 3 months and 4.5 years. We calculated maternal mood levels as the sum of mood symptoms and computed maternal mood entropy by applying Shannon’s entropy to the distributions of mood questionnaire responses. Maternal mood measures were not associated with amygdala volumes; however, mood entropy was directly associated with smaller hippocampal volumes at age 4.5 years and indirectly associated with smaller hippocampal volumes at 10.5 years through rank-order stability over time. These effects were present beyond the effects of socioeconomic status and intracranial volume and were specific to mood entropy, not mood levels. Our findings indicate that patterns of maternal mood are embedded in early childhood brain structure, setting the stage for subsequent neurodevelopment.

Personality of young adults born prematurely: the Helsinki study of very low birth weight adults / Anu-Katriina PESONEN in Journal of Child Psychology and Psychiatry, 49-6 (June 2008)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 49-6 (June 2008) . - p.609-617 Titre : Personality of young adults born prematurely: the Helsinki study of very low birth weight adults Type de document : texte imprimé Auteurs : Anu-Katriina PESONEN, Auteur ; Katri RAIKKONEN, Auteur ; Eero KAJANTIE, Auteur ; Kati HEINONEN, Auteur ; Anna-Liisa JARVENPAA, Auteur ; Sture ANDERSSON, Auteur ; Petteri HOVI, Auteur ; Johan G. ERIKSSON, Auteur Année de publication : 2008 Article en page(s) : p.609-617 Langues : Anglais (eng) Mots-clés : Birth-weight prematurity longitudinal-studies personality risk-factors resilience adulthood Index. décimale : PER Périodiques Résumé : Background: Today, the first generations of very low birth weight (VLBW ≤ 1500 g) infants are entering adulthood but very little is known of their personality traits, associated with both psychopathological vulnerability and resilience. Methods: In this cohort study we compared personality traits among young adults (age range 18 to 27 years, mean 21.4, SD 2.19) with VLBW (n = 158) with those of term-born controls (n = 168) of same gender, age, and maternity hospital. The participants completed the Neo-Personality Inventory. Results: Of the five main traits, the VLBW participants scored significantly higher in conscientiousness (MD .1, 95% CI .0 to .3; p < .03), agreeableness (MD .2, 95% CI .0 to .3; p < .001), and lower in openness to experience (MD –.1, 95% CI –.2 to .0; p < .02). In addition, the VLBW group differed from the controls with regard to facets of neuroticism (lower hostility and impulsivity, ps < .05) and extraversion (less assertiveness p < .01). Furthermore, there were fewer undercontrolled personality profiles among the VLBW subjects (p < .01). All differences were independent of gender, age at assessment, parental education, individual school grade average, and maternal pre-eclampsia and smoking during pregnancy. Conclusions: Young adults born with VLBW showed markedly different personality traits compared with their controls. The VLBW group displayed less negative emotions, were more dutiful and cautious, and displayed more warmth in their social relationships than their term-born peers. We present two potential mechanisms underlying these findings. The first relates to parental influences and the other to evidence linking biological mechanisms associated with prematurity with personality characteristics in adulthood.
