Obese Kids as Young as 8 Show Heart Disease Signs

TUESDAY, Nov. 10, 2015 (HealthDay News) -- Obese children can develop signs of heart abnormalities as young as age 8, which might drive up their risk for early death as adults, new research suggests.
"It is both surprising and alarming to us that even the youngest obese children in our study who were 8 years old had evidence of heart disease," said study lead author Linyuan Jing, a postdoctoral fellow with Geisinger Health System in Danville, Pa.
"Ultimately, we hope that the effects we see in the hearts of these children are reversible," Jing added. "However, it is possible that there could be permanent damage."
For the study, Jing's team conducted MRI scans of 40 children between 8 and 16 years old. Half were obese; half were of normal weight.
The obese kids had an average of 27 percent more muscle mass in the left ventricle region of their heart, and 12 percent thicker heart muscle overall. Both are considered indicators of heart impairment, Jing said.
Also, among 40 percent of the obese children, scans showed thickened heart muscle had already translated into a reduced ability to pump blood. Kids with this reduced heart capacity were deemed to be at "high risk" for adult cardiac strain and heart disease.
"This should be further motivation for parents to help children lead a healthy lifestyle," Jing said.
Dr. Gregg Fonarow, a professor of cardiology at the University of California, Los Angeles, called the findings "alarming."
He and Jing said the structural heart changes detected by the scans are associated with more complicated health conditions in adulthood as well as early death in adults.
The changes in heart muscle mass "suggest a significant increase in risk of heart failure, arrhythmia [irregular heartbeat] and premature cardiovascular death in children with obesity," said Fonarow, who was not involved with the study.
Jing said the study results suggest obese children even younger than 8 years old likely have signs of heart disease, too. "Understanding the long-term ramifications will be critical as we deal with the impact of the pediatric obesity epidemic," she said.
