TUESDAY, March 22 (HealthDay News / HolaDoctor) - A recent study suggests that Obesity often prepares adolescents for a wide variety of conditions that increase the risk of heart disease, such as inflammation, insulin resistance and signs of trouble in the metabolic system.
"Metabolic abnormalities suggest that the process of developing heart disease has already begun in these children, making it critical to introduce changes in diet and lifestyle," he said in a press release issued by the American Heart Association Dr. Ashutosh Lal, author of the study and pediatric hematologist at Children's Hospital & Research Center Oakland in California.
The findings were presented Tuesday at the Scientific Sessions of the American Heart Association in Atlanta.
The researchers compared the diets of 33 obese young people between eleven and 19 years with the other 19 of the same age group who were normal weight. Weight category of participants was determined using body mass index, a ratio of weight and height of a person.
Researchers also examined the results of blood tests of each of the participants, who received medical care at a clinic in downtown Oakland. Two thirds of participants in each group were female and were racially diverse groups.
Researchers found that obese adolescents showed signs of inflammation, insulin resistance (a precursor to diabetes) and oxidative stress (which can lead to damaged blood vessels).
"Examining the figures, you may think that these children may feel sick, but it was not," said Lal. "Apparently they felt fine, but there is much that lies beneath the surface."
problems could be related to poor diets low in fruits and vegetables, fiber and dairy. The researchers found that adolescents of both groups were not receiving adequate nutrition because they do not consume enough of these types of foods, although obese adolescents in particular consumed less milk and fewer servings of fruit.
The study authors indicated that it was found that potassium and vitamins A, C and D, found in fortified dairy products and fruits and vegetables in bright colors, were absent in the diets of obese children.
"The obese consumed very few natural sources of antioxidants, fruits and vegetables, and may have greater need for antioxidants in the inflammation associated with excess [weight]," said Lal. "For heart health, obese adolescents should eat better, not just less." Experts say
that research presented at meetings are not subject to the same kind of rigorous scrutiny than those published in peer-reviewed medical journals.
