Researchers in Italy analyzed the health data of more than 5,700 healthy kids between the ages of 2 and 6 years. Roughly 10 percent of the children had become overweight or obese in the last year, and nearly half of that group was already showing signs of being at a higher risk of developing heart disease and diabetes.
Metabolic indicators such as high blood pressure, high cholesterol and elevated blood sugar levels were present even in children who had only been obese for a short period of time, and scientists believe those indicators could lead to health problems earlier in adulthood.
The results prompted researchers to recommend screening kids at a younger age to detect such abnormalities, especially if there is a family history. They also encourage healthy diet and lifestyle choices such as increasing daily physical activity and reducing the amount of trans fats and sugar consumed.
