Study Finds Obese Children Display Early Signs of Heart Disease
Oct 19, 2007
A study published in the winter issue of the Journal of Cardiometabolic Syndrome suggests that obese children display early signs of heart disease similar to those exhibited by obese adults with heart disease, United Press International reports. To evaluate heart disease symptoms within the pediatric population, researchers from the Washington University School of Medicine in St. Louis studied 168 children ages 10 to 18 with symptoms including heart murmur, chest pain, acid reflux or high cholesterol.
Based on body mass index for age (BMIA) guidelines, 33 patients were classified as obese, 20 were labeled at risk for obesity and 115 were considered to be at normal weight. By assessing changes in each patient’s heart muscle motion, the researchers found that as a child’s BMIA increased, both the relaxation and contraction phases of the heart beat changed in a manner similar to the changes seen in adults.
Angela Sharkey, M.D., an author of the study, noted that "many of these changes that have been seen in adults were assumed to be from long-standing obesity, but it may be that these changes start much earlier in life." She suggests that future research seek to determine at what age cardiac changes occur and whether those changes could be reversed with weight loss.
The researchers further recommend that pediatricians use the findings to counsel children and their parents about the serious risks of obesity and the benefits of maintaining a healthy lifestyle.
