GODFREY, Auteur ; SOUTHAMPTON WOMEN'S SURVEY STUDY GROUP, Auteur Année de publication : 2009 Article en page(s) : p.816-823 Langues : Anglais (eng) Mots-clés : nutrition infancy weaning intelligence neuropsychology Index. décimale : PER Périodiques Résumé : Background: Trials in developing countries suggest that improving young children's diet may benefit cognitive development. 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.

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.
