Whether dietary composition influences young children's cognition in developed countries is unclear. Although many studies have examined the relation between type of milk received in infancy and subsequent cognition, there has been no investigation of the possible effect of variations in the weaning diet. Methods: We studied 241 children aged 4 years, whose diet had been assessed at age 6 and 12 months. We measured IQ with the Wechsler Pre-School and Primary Scale of Intelligence, visual attention, visuomotor precision, sentence repetition and verbal fluency with the Developmental Neuropsychological Assessment (NEPSY), and visual form-constancy with the Test of Visual Perceptual Skills. Results: In sex-adjusted analyses, children whose diet in infancy was characterised by high consumption of fruit, vegetables and home-prepared foods ('infant guidelines' dietary pattern) had higher full-scale and verbal IQ and better memory performance at age 4 years. Further adjustment for maternal education, intelligence, social class, quality of the home environment and other potential confounding factors attenuated these associations but the relations between higher 'infant guidelines' diet score and full-scale and verbal IQ remained significant. For a standard deviation increase in 'infant guidelines' diet score at 6 or 12 months full-scale IQ rose by .18 (95% CI .04 to .31) of a standard deviation. For a standard deviation increase in 'infant guidelines' diet score at 6 months verbal IQ rose by .14 (.01 to .27) of a standard deviation. There were no associations between dietary patterns in infancy and 4-year performance on the other tests. Conclusions: These findings suggest that dietary patterns in early life may have some effect on cognitive development. It is also possible that they reflect the influence of unmeasured confounding factors.

Effortful control mediates associations of fetal growth with hyperactivity and behavioural problems in 7- to 9-year-old children / Wolff SCHLOTZ in Journal of Child Psychology and Psychiatry, 49-11 (November 2008)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 49-11 (November 2008) . - p.1228-1236 Titre : Effortful control mediates associations of fetal growth with hyperactivity and behavioural problems in 7- to 9-year-old children Type de document : Texte imprimé et/ou numérique Auteurs : Wolff SCHLOTZ, Auteur ; Keith M. GODFREY, Auteur ; Alexander JONES, Auteur ; David I.W. PHILLIPS, Auteur Année de publication : 2008 Article en page(s) : p.1228-1236 Langues : Anglais (eng) Mots-clés : Fetal-growth temperament effortful-control behavioural-problems hyperactivity birth-weight Index. décimale : PER Périodiques Résumé : Background: Inverse associations of fetal growth with behavioural problems in childhood have been repeatedly reported, suggesting long-term effects of the prenatal developmental environment on behaviour later in life. However, no study so far has examined effects on temperament and potential developmental pathways. Temperamental traits may be particularly susceptible to neurodevelopmental alterations, and they are linked to behavioural problems. Therefore, we tested for associations of fetal growth with behavioural problems in children and tested if temperament mediated such effects. Methods: One hundred and thirty-nine mother–child pairs were recruited in early pregnancy. Weight, head circumference and gestational age were measured at birth, and the mother reported on their child's behavioural problems and temperament at age 7 to 9 years. Results: Birth weight and head circumference at birth adjusted for gestational age (i.e., fetal growth) were inversely associated with hyperactivity and total behavioural problems, and positively associated with the temperamental trait Effortful Control. Path analyses showed that Effortful Control mediated the effects of fetal growth on hyperactivity and total behavioural problems. Conclusions: Our results suggest that an adverse fetal environment is associated with behavioural problems in childhood, in particular in those children that show a low capacity for attentional and behavioural regulation. An adverse fetal environment might induce vulnerability for behavioural problems, or it might induce changes in temperament and behavioural problems independently, representing a common cause. Pathways are likely to be based on long-lasting neurodevelopmental alterations due to prenatal adversity.

Lower maternal folate status in early pregnancy is associated with childhood hyperactivity and peer problems in offspring / Wolff SCHLOTZ in Journal of Child Psychology and Psychiatry, 51-5 (May 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-5 (May 2010) . - p.594-602 Titre : Lower maternal folate status in early pregnancy is associated with childhood hyperactivity and peer problems in offspring Type de document : Texte imprimé et/ou numérique Auteurs : Wolff SCHLOTZ, Auteur ; Sian M.

We examined for associations of maternal folate status and dietary intake during pregnancy with brain growth and childhood behavioural difficulties in the offspring. Methods: In a prospective cohort study, maternal red blood cell folate (RCF) was measured at 14 weeks of pregnancy and total folate intake (TFI) from food and supplements was assessed in early and late pregnancy. The offspring's head circumference and body weight were measured at birth and in infancy, and 100 mothers reported on children's behavioural difficulties at a mean age of 8.75 years using the Strengths and Difficulties Questionnaire. Results: Lower maternal RCF and TFI in early pregnancy were associated with higher childhood hyperactivity (RCF: beta = −.24; p = .013; TFI: beta = −.24; p = .022) and peer problems scores (RCF: beta = −.28; p = .004; TFI: beta = −.28; p = .009) in the offspring. Maternal gestational RCF was positively associated with head circumference at birth (adjusted for gestational age), and mediation analyses showed significant inverse indirect associations of RCF with hyperactivity/inattention and peer problems via fetal brain growth. Adjustment for mother's smoking and drinking alcohol during pregnancy did not change the results. Conclusions: Although the associations are small and residual confounding is possible, our data provide preliminary support for the hypothesis that lower folate status in early pregnancy might impair fetal brain development and affect hyperactivity/inattention and peer problems in childhood.

Oily fish intake during pregnancy – association with lower hyperactivity but not with higher full-scale IQ in offspring / Catherine GALE in Journal of Child Psychology and Psychiatry, 49-10 (October 2008)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 49-10 (October 2008) . - p.1061-1068 Titre : Oily fish intake during pregnancy – association with lower hyperactivity but not with higher full-scale IQ in offspring Type de document : Texte imprimé et/ou numérique Auteurs : Catherine GALE, Auteur ; Sian M. ROBINSON, Auteur ; Keith M. GODFREY, Auteur ; Catherine M. LAW, Auteur ; Wolff SCHLOTZ, Auteur ; F. J. O'CALLAGHAN, Auteur Année de publication : 2008 Article en page(s) : p.1061-1068 Langues : Anglais (eng) Mots-clés : Intelligence behaviour-problems diet pregnancy fish-intake hyperactivity omega-3 fatty-acids nutrition pre-natal Index. décimale : PER Périodiques Résumé : Background: Long-chain omega-3 polyunsaturated fatty acids are thought to be important for fetal neurodevelopment. Animal studies suggest that a deficiency of omega-3 fatty acids may lead to behavioural or cognitive deficits. As oily fish is a major dietary source of omega-3 fatty acids, it is possible that low intake of fish during pregnancy may have adverse effects on the developing fetal brain. Methods: We used the Strengths and Difficulties Questionnaire and the Wechsler Abbreviated Scale of Intelligence to assess behavioural problems and intelligence in 217 nine-year-old children. The mothers of these children had participated in a study of nutrition during pregnancy during which fish intake was assessed in early and late gestation. Results: Children whose mothers had eaten oily fish in early pregnancy had a reduced risk of hyperactivity compared to those whose mothers did not eat oily fish: OR .34, 95% CI .15 to .78, after adjustment for potential confounding factors. Children whose mothers had eaten fish (whether oily or non-oily) in late pregnancy had a verbal IQ that was 7.55 points higher (95% CI .75 to 14.4) than those whose mothers did not eat fish. There were, however, no significant associations between fish intake in pregnancy and other behavioural problems or full-scale and performance intelligence, after adjustment for potential confounding factors. Conclusions: Although maternal fish intake in pregnancy was associated with hyperactivity scores and verbal IQ in children, in general, how much fish women ate during pregnancy appeared to have little long-term relation with neurodevelopmental outcomes in their child.
