Healthy lifestyles can help address childhood obesity problems

Girls in relay raceTwo in three severely obese children already have at least one risk factor for heart disease, new research shows.

The study findings revealed 67 per cent of 307 severely obese children had at least one risk factor for heart disease. Over half had high blood pressure and a similar proportion had high levels of low density (LDL), or bad, cholesterol. Fourteen per cent had high fasting blood glucose and just under one per cent had type 2 diabetes.

Type 2 diabetes, high blood cholesterol and high blood pressure are all modifiable risk factors for heart disease.

The researchers’ definition of severe obesity started at a body mass index (BMI) of 20.5 for a 2-year-old, 31 for a 12-year-old, and 35 for an 18-year-old. They found only one child's obesity was attributable to medical rather than lifestyle factors.

This is a problem that can be addressed by stopping young people becoming overweight and obese in the first place

Doireann Maddock, our Senior Cardiac Nurse, 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.”

Our Food4Thought campaign aims to help tackle childhood obesity and encourage children to lead a healthier lifestyle.
