Increasing the amount of vigorous exercise can decrease the risk of developing type 2 diabetes and cardiovascular disease in children, reports a new study. The findings of the study are published in the Scandinavian Journal of Medicine & Science in Sports.

Physical exercise can reduce the risk factors of type 2 diabetes and cardiovascular disease even in children, a new study from the University of Eastern Finland shows.

In a two-year follow-up of primary school children, sedentary behavior increased the accumulation of risk factors, whereas increasing the amount of vigorous exercise reduced it. This is one of the first follow-up studies to reliably demonstrate these associations in children.

The results are based on follow-up data from the Physical Activity and Nutrition in Children (PANIC) Study, ongoing at the University of Eastern Finland. Conducted in collaboration with scientists from the University of Cambridge, the Norwegian School of Sport Sciences and the University of Copenhagen.

The two-year follow-up study analyzed associations of changes in the amount of vigorous, moderate and light exercise, as well as sedentary behavior, with risk factors of type 2 diabetes and cardiovascular diseases, such as body fat content, waist circumference, blood insulin, and glucose levels, blood lipids and blood pressure.

The amounts of vigorous, moderate and light exercise, as well as sedentary behavior, were objectively measured using the Actiheart® device, which records heart rate and body movement. Children wore the Actiheart® device continuously for a minimum of four days, and the measurement period included weekdays and days of the weekend.

During the two-year follow-up, the overall risk and individual risk factors of type 2 diabetes and cardiovascular reduced in children who increased their amount of vigorous exercise. In children whose sedentary behavior increased, the risk increased as well. These changes were independent of gender, biological maturity, and lean body mass, as well as of the levels of risk factors and physical activity measured at the beginning of the study.

The study is highly significant, as it is one of the first follow-up studies in the world to reliably show that increasing the amount of vigorous exercise is independently associated with a reduced risk of type 2 diabetes and cardiovascular disease in ordinary primary school children.

"A physically passive lifestyle is gradually becoming alarmingly widespread among children and young people almost all over the world. Our findings provide support for the role of physical activity in preventing common chronic diseases already in childhood," says Researcher Juuso Väistö, the first author of the article, from the University of Eastern Finland.

He points out that children and young people should engage in more physical exercise than what it takes to go about their daily activities.

"Our findings show that increasing the amount of vigorous exercise and reducing sedentary behavior are equally important in preventing type 2 diabetes and cardiovascular disease. According to the latest recommendations, children need diverse physical activity every day, and at least 60 minutes should be vigorous exercise. In practice, vigorous exercise refers to exercise or games that cause shortness of breath and perspiration."

Prevention of type 2 diabetes and cardiovascular disease are best begun already in childhood.

The PANIC Study has earlier shown that the accumulation of risk factors of type 2 diabetes and cardiovascular disease, which typically exists in people who are overweight, often begins already in childhood. This is a cause for concern, as the accumulation of risk factors in childhood significantly increases the risk of these diseases in adulthood.

According to this newly published study, regular exercise and avoiding a physically passive lifestyle constitute efficient means of mitigating the risk factors type 2 diabetes and cardiovascular disease.

PANIC Study - a source of scientifically valuable data on children's health

The Physical Activity and Nutrition in Children (PANIC) Study is an on-going lifestyle intervention study. A total of 512 children aged 6 to 8 years participated in the onset measurements in 2007-2009. The study applies scientifically sound methods to extensively study the lifestyles, health, and well-being of children.

The study provides novel information on children's physical activity, sedentary behaviour, nutrition, physical fitness, body composition, metabolism, cardiovascular system function, brain function, oral health, life quality, effects of exercise and nutrition on children's health and well-being, and on the effects of these factors on health care costs.
