Food additives and children's behaviour: evidence based policy at the margins of certainty
Full text linkThe possible effects of food additives (specifically artificial colours) have been debated for over 30 years. The evidence accumulated suggests that for some children with attention deficit hyperactivity disorder (ADHD) food colours exacerbate their condition. Two studies
undertaken by a research group at the University of Southampton have extended these findings to the effects on hyperactivity in children from the general population who do not show ADHD. This article reviews the response from policy-makers to these findings and concludes that the failure to impose a mandatory ban on the six food colours in the Southampton study is inadequate and that such a ban would be an appropriate application of the precautionary principle when the evidence is considered to be at the margins of certaint
Recent research on food additives: Implications for CAMH
No full textThe question of the possible role of food additives, and specifically food colours, in elevating hyperactive behaviour in children has been long debated. There is now replicated evidence that the removal of food colours from the diet can make a small improvement in the behaviour of some children with ADHD. However, as yet the characteristics of those who benefit from this dietary change are unknown. Two studies from a research group at Southampton have extended this work to show that some children from the general population without ADHD show a similar benefit. The implications of these findings for those in CAMH services are discussed. They are considered alongside other forms of dietary treatment for ADHD such as the use of ‘few foods’ diet and omega-3 fatty acids.<br/
The treatment of the long-term sequelae of child abuse
No full textThe literature on the long-term sequelae of sexual and physical abuse is reviewed. Abused children are at risk of long-term adverse psychological sequelae related to the abuse per se and not just as a consequence of other associated background factors. There is some specificity relating the type of psychological outcome to the type of abuse experienced. Physical abuse is just as traumagenic as sexual abuse in the long-term. Whatever the efficacy of specific psychological treatments, there are broad general service measures that will prevent both abuse and re-abuse and therefore impact on long-term sequelae. The studies on the effectiveness of intervention to prevent psychological sequelae of abuse are systematically appraised. There are few well-conducted and adequately controlled studies of the efficacy of treatment for abused children. Where a corpus of studies does exist, e.g. group therapy for sexually abused children, treatment for abused children appears to be as effective for children whose problems arise from other causes. Studies have also shown that abusive parenting can be changed by training
Relationship between behavior and asthma in children with atopic dermatitis
No full textOBJECTIVE: The significance of psychological factors in asthma is a subject of considerable dispute. This study addressed the little investigated question of the potential role of psychological factors in the initial onset of asthma.MATERIALS AND METHODS: Data on the validated, standardized Behavior Screening Questionnaire were obtained prospectively from 35 to 53 months for 150 atopic children who had asthma by age 53 months and for 115 who did not.RESULTS: At each age, the children who had asthma by 53 months had more behavior problems. There was no evidence that the subsequent behavior of those children who had asthma became more problematic. However, for those children without asthma by 35 months, an elevated behavior problem score at that age was related to the subsequent onset of asthma by age 53 months. The behavior problem score added significantly to the prediction of asthma onset (OR adjusted: 1.15; 95% CI: 1.02–1.29) when known risk factors of asthma and IgE levels for grass pollen and house dust mite at age 17 months were taken into account.CONCLUSIONS: Behavior problems may precede asthma onset in young atopic children. In this age group, behavior problems are not secondary psychological reactions to asthma onset. They may act as a marker for stress in the child’s life. The presence of behavior problems should alert clinicians that the child may be at increased risk for transition from atopic dermatitis to asthma
Dietary influences on cognitive development and behaviour in children
Get PDFThere are a number of ways in which food can influence behaviour, including malnutrition, types of diet, eating habits, pharmacological effects, food allergy, fatty acid deficiency and possibly food additives. The range of behaviour affected is also wide, and includes attention, conduct disorder and mood. A particular focus of interest has been the effects of food on hyperactivity in children. There is some initial evidence that fatty acids may influence hyperactivity in children with specific learning disabilities. The findings also suggest that some food additives (colourings, flavourings and preservatives) may increase hyperactivity in children with behaviour problems. For children showing behaviour problems such as hyperactivity the use of dietary manipulation tends to be a more acceptable approach to treatment than the use of drugs. However, there needs to be awareness of the dangers of the use of unsupervised restriction diets with children, and the use of dietary treatments alone is not likely to be sufficient treatment for many children with attention-deficit hyperactivity disorder. A study is currently underway to investigate the possible effects of additives on behaviour in the general population of childre

No full textThe structure of genetic influences on general cognitive, language, phonological, and reading abilities
No full textFollowing models that describe intraindividual correlates of stage transitions (S. S. Snyder & D. H. Feldman, 1984), this study assessed the relation between a measure of consolidation and transition in moral judgment development and the utility of moral concepts in sociomoral decision making. The study extends previous research in suggesting that individuals use moral concepts differently as they cycle through periods of consolidation and transition. With multiple cross-sectional and longitudinal samples, findings indicate that participants' reliance on a Kohlbergian moral framework as measured by the Defining Issues Test is highest during periods of consolidation and lowest during transitions. As participants move into periods of consolidation, the utility of moral stage information increases. Thus, this study indicates that the consolidation and transition model can be used to help identify individuals who are more or less likely to use Kohlberg's moral stages in their moral decision making
Executive functions in school-aged children born very prematurely
No full textAbstractBackgroundSchool-age preterm children are at risk for cognitive difficulties including Executive Dysfunction and low average IQ.AimThe aim of this study was to determine the performance of very preterm, school-age children on three components of Executive Function (EF), two components of Executive Attention and a measure of IQ.Study designCross-sectional, independent samples comparison.MethodsA UK sample of 40 very preterm (< 32 weeks gestational age, mean 28.43, SD 2.41) children and 41 term born control children aged between 6 and 12 years (mean ages 8 years 5 months in both groups) was assessed on IQ, EF (inhibition, working memory and set shifting) and attention (sustained and selective). Between group comparisons were made using multivariate analysis of variance and covariance.ResultsMultivariate analyses indicated that preterm children scored significantly lower than their term born peers across Executive Function and executive attention tasks. As expected, the preterm group achieved IQ scores at the low end of the average range. Univariate analyses indicated some difficulties with shifting and inhibition components of EF, although covariate analysis revealed that only shifting was independent of IQ.ConclusionsPreterm children showed mild executive function and executive attention difficulties in the context of average IQ scores. The findings highlight the benefit of using multivariate assessments of executive skills rather than general intellectual outcome alone, to obtain a better distinction of the specific cognitive weaknesses associated with preterm birth
