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.

Small body size at birth and behavioural symptoms of ADHD in children aged five to six years / J. LAHTI in Journal of Child Psychology and Psychiatry, 47-11 (November 2006)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 47-11 (November 2006) . - p.1167–1174 Titre : Small body size at birth and behavioural symptoms of ADHD in children aged five to six years Type de document : Texte imprimé et/ou numérique Auteurs : J. LAHTI, Auteur ; Katri RAIKKONEN, Auteur ; Eero KAJANTIE, Auteur ; Kati HEINONEN, Auteur ; Anu-Katriina PESONEN, Auteur ; Anna-Liisa JARVENPAA, Auteur ; T. STRANDBERG, Auteur Année de publication : 2007 Article en page(s) : p.1167–1174 Langues : Anglais (eng) Mots-clés : Birth-weight ponderal-index head-circumference ADHD attention hyperactivity length-of-gestation term Index. décimale : PER Périodiques Résumé : Background: Behavioural disorders with a neurodevelopmental background, such as attention deficit hyperactivity disorder (ADHD), have been associated with a non-optimal foetal environment, reflected in small body size at birth. However, the evidence stems from highly selected groups with birth outcomes biased towards the extreme low end of the distribution in birth weight. Whether a similar association exists among the normal range of term birth is unclear. Methods: The ADHD Rating Scale was filled in by the biological mothers and fathers of children aged five to six years who were born healthy at term. Information on weight (kg), height (cm), head circumference (cm), and gestational age at birth were obtained from hospital records, and the ponderal index (kg/m3), a commonly used measure of thinness, and head circumference-to-length ratio were calculated. Results: Behavioural symptoms of ADHD were predicted by a lower ponderal index, a smaller head circumference, and a smaller head circumference-to-length ratio (β's: −.12 to −.14, p's < .05). Adjustments for length of gestation, mother's age, tobacco and alcohol use during pregnancy, pre-pregnancy body mass index (BMI), or parity, the monthly gross income of the family, child's BMI at the age of five to six years or gender did not change the associations. Conclusion: These results suggest that physiological adaptation in utero, indicated by small body size at birth, within term gestational range may increase the susceptibility to behavioural symptoms of ADHD.
