Metabolic disorders, such as excess abdominal fat, raised blood pressure, higher levels of insulin, glucose and triglycerides and lower levels of the beneficial HDL cholesterol can be found in children as young as 6 to 8 years of age, according to a study carried out at the University of Eastern Finland. These metabolic risk factors often accumulate in overweight children and, in the newly published study, this accumulation was linked with mild artery wall stiffness. Of single disorders, higher levels of insulin, triglyceride and blood pressure were associated with artery wall stiffness. In addition, boys with excess abdominal fat and higher blood pressure levels were related to a reduced arterial dilation after maximal exercise in a bicycle test. The results were published today in Circulation Journal.
The researchers analyzed the relations of overweight, impaired glucose and fat metabolism and blood pressure to artery wall stiffness and arterial dilation capacity in 173 healthy children aged 6 to 8 years in Kuopio, eastern Finland. The study comprised part of the wider Physical Activity and Nutrition in Children (PANIC) study, which is carried out by a research group in the Institute of Biomedicine at the University of Eastern Finland. The PANIC study provides novel and scientifically valuable information on children's physical activity, nutrition, fitness, body composition, metabolism, vascular function, learning, oral health, sleep, pain and other factors of the quality of life. The original subject group was a population sample of 512 children from the city of Kuopio who were 6
