A study that examined 255 severely obese children aged between two and 18 has found that majority of obese children below age 12 run the risk of heart disease.
Nearly 67% of the children studied carried atleast one risk factor for heart disease and the most common risk factor was hypertension.
British Heart Foundation senior cardiac nurse Doireann Maddock said: "Although it was a small study, the findings leave a bad taste in the mouth. It's a huge concern so many obese children were identified as already having at least one risk factor for heart disease, including high blood pressure, high blood glucose and problems with cholesterol levels.
"However, this is a problem that can be addressed by stopping young people becoming overweight and obese in the first place. Highlighting the importance of healthy eating and physical activity from an early age will help protect the heart health of future generations."
