Excess weight is the mother makes the child autism, scientists warn
Development problems in children, including autism, may be due to the presence of maternal obesity, disturbances in metabolism and diabetes. Corresponding risk increases by more than 1.5 times, RIA "Novosti" with reference to the research floors Krakowiak University of California.
According to statistics, more than one third of the residents of the States of childbearing age are overweight, and 10% of the time during pregnancy develop diabetes. As stated Krakowiak, all this is reflected in the alarming rates of autism in the country, because obese women affects child development.
Experts have identified this relationship as an example of about 1000 pairs of mothers and their children. In 517 children was diagnosed with "autism spectrum disorder". Even in 172 recorded other developmental disorders. The analysis showed that the presence of obesity in the mother at the time of pregnancy increases the chance of a sick child in the light of 1.6 times.
In the group of children for more than 20% of the mothers were overweight. But in the healthy group figure was 14%. Diabetes increased the risk of abnormalities in more than 2 times. In total, about 29% of autistic children born to mothers with problems with metabolism, and in the group of healthy children the figure was 19%.
Scientists explain this relationship as follows: obesity triggers diabetes, hypertension, resistance to insulin and chronic inflammation. Elevated levels of sugar in the blood of women in the child increases the production of insulin. But this process requires more oxygen, which threatens to oxygen deprivation has a negative impact on brain development.
