Points of risk of obesity of children in pregnancy

What eats a mother during pregnancy can put her baby to an increased risk of obesity, suggests new research presented at a Summit of obesity in Montreal.

National Summit of the Canadian obesity network includes more than 800 delegates discuss prevention and treatment of public, political prospects and legal genetic health, nutrition,

A child touches the belly of its mother house in the last stages of her pregnancy. Pregnant with high cholesterol or acidic levels fatty women are more likely to have children later became obese and develop Type 2 diabetes, researchers only. Regis Duvignau/Reuters.

Physicians and researchers, the focus of prevention begins to move - in the uterus.

Dr. Jill Hamilton, a pediatric endocrinologist at the Hospital for Sick Children in Toronto, said emerging research shows pregnant women with high levels of cholesterol and fatty acid levels is more likely to have children later became obese and develop Type 2 diabetes.

"Some of these molecules can be transmitted to the baby and influence how the baby develops, Hamilton a."It may affect the programming of channels in the brain linked to appetite.""

Factors in the uterus can interact to change permanently the gene expression without actually changing the structure of DNA. The process is called epigenetics, and changes can affect how DNA instructions are interpreted as cells, proteins and the other in the body building blocks are formed.

In the research on obesity, "epigenetic" changes relate to the regulation of appetite. Those that can affect the way the body handles glucose fuel in food, which increases the likelihood that a child could develop resistance to insulin, or obesity, said Hamilton.

This week, Dr. Keith Godfrey, Professor of epidemiology and human development at the University of Southhamptom, in England and his colleagues published their results in the journal of diabetes. For the first time, the study showed that nutrition for women during pregnancy can change how DNA child works and bring the children to develop more fat.

The team of Godfrey measured epigenetic markers in nearly 300 children at birth. Markers explained at least 25% of the difference of adiposity when children have been studied again in six or nine years - or average a difference of about two kilograms for a 30 kilogram nine years.

"Remarkably, simple changes in the diet of the mother during pregnancy can permanently change appetite and levels of physical activity in the offspring," Godrey said previous studies on animals.

For Jolyn Swain, in Halifax, who is four months pregnant research changes any for it.

"It gives me envy to participate more, it gives me want to keep these journals of food and check the boxes," said Swain.

Researchers have said that they cannot prescribe specific foods to eat or avoid pregnancy. The conclusions also do not change current nutritional advice for pregnant women, apart from giving a another important reason to follow.

The Conference extends to May 1.
