Experts examine how a diet high in fat and sugar could vary newborn DNA in a way that might cause behavioural problems
A diet high in fat and sugar during pregnancy may be linked to attention deficit hyperactivity disorder in children around behavioural problems early in life, experts have found.
The research, led by scientists from Kings College London( KCL) and the University of Bristol, is believed to be the first explained that an unhealthy diet alters the babys DNA in a way that might lead to brain changes and later ADHD .
ADHD and deport difficulties are the most common reasons for child mental health issues referral in the UK and tend to occur in tandem. More than 40% of children around a diagnosis of behavioural problems also have a diagnosis of ADHD.
A high flab, high carbohydrate nutrition in pregnancy had already been associated with behavioural both problems and ADHD, but the study, published in the Journal of Child Psychology and Psychiatry on Thursday, attempts to look at the relevant procedures involved.
Studying participants from the Bristol-based Children of the 90 s cohort, the experts equated 83 children around early-onset lingering deport problems linked to 81 children who had little of manage problems. They assessed how the mothers nutrition changed IGF2, a gene to participate in foetal proliferation and the development of the cerebellum and hippocampus, areas of the intelligence implicated in ADHD.
The outcomes pictured high fatty and carbohydrate foods of processed food and confectionery were associated with greater modification of IGF2 in both sets of children. Higher IGF2 methylation was also associated with higher ADHD indications between the ages of 7 and 13, but merely in the case of children who showed an early onset of behavioural problems such as lying or fighting.
Co-author Dr Edward Barker, from government departments of psychology at KCL, should be pointed out that parents with children with ADHD should not blame themselves because diet was just one influence, albeit a potentially large one.
ADHD/ manage difficulties are very complex psychiatric problems, they find themselves multi-determined, he said. Diet could be an important but its going to be important alongside a host of other probabilities. A sensible diet can improve indications but its not a single causal agent.
He also said the results did not prove causation and needed to be replicated in larger studies, but added to a weight of evidence about the importance of diet for good mental health.
Diet can affect a range of psychiatric questions, he said. Theres good proof that diet can affect hollow. Of trend it feigns obesity, but obesity is related to how we feel about ourselves and can be related to ADHD.
Dr Max Davie, mental health issues make at the Royal College of Paediatrics and “Childrens health”, said the hypothesis applied to a fairly small subset of children.
It may be situations where the mothers with a worse diet are more reckless by nature, and hence is very hard to balk undesirable alternatives, and this inherited predisposition is, at the least in part, responsible for the fact that there is ADHD symptoms in their children, he said.
At present, this is not a study that would change my clinical practise, but if intervention investigates resulting from this work evidence nutritional funding in pregnancy can have an effect then we should take any opportunity we can to help.
