Obese children 'heading for diabetes'
![]() Blood testing revealed blood sugar problems in children
A quarter of obese children are already showing signs of changes that could lead to full-blown diabetes.
The finding supports doctors' fears that many of today's "couch potato generation" could be falling prey to the disabling disease before they hit their 30s. It has been known for some time that being obese, or even overweight, can greatly increase the chances of diabetes, but evidence is growing that younger and younger patients are at risk. The study, by researchers at Yale University in the US, looked at more than 150 obese children, aged between four and 18. They found that in the 55 aged four to 10, 25% were showing signs of "insulin resistance".
People with insulin resistance can go on to develop diabetes, in which blood sugar levels often cannot be brought under control without treatment. The researchers found that even in the 11 to 18 age group, 21% had signs of insulin resistance. Already diabetic Four of the adolescents had "silent" diabetes, meaning they already had the disease, but had no obvious symptoms. Associate Professor of Endocrinology Sonia Caprio, who led the study, said: "Most of the children are at high risk for type II diabetes. "And, if they develop diabetes before the age of 20, they face a lifetime of being at very high risk for complications." These complications include early heart disease, eye and kidney disorders. Poor circulation in the legs and feet can also contribute to slow-healing ulcers, which can lead to permanent damage. Lifestyle change Currently, this kind of diabetes is often termed "late onset diabetes", as most new cases arise among people in middle age or older. However, Dr Susan Jebb, from the Medical Research Council Centre for Human Nutrition in Cambridge, said that this was further evidence that the disease was likely to strike younger patients in future. She said: "If you are 15 or 20 when diabetes strikes, you are much more likely to suffer from complications." However, she said that there was no reason to suppose that the damaging changes already happening in pre-teen children could not be reversed if they began to lose weight. She said: "Being overweight is a serious risk to your child's health - if you want to protect your children's, you need to change your whole family's lifestyle." The study was published in the New England Journal of Medicine.
