What is it about?

During the two-year follow-up, the overall risk and individual risk factors of type 2 diabetes and cardiovascular diseases reduced in children who increased their amount of vigorous exercise. In children whose sedentary behaviour increased, the risk increased as well.

Why is it important?

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. These findings provide support for the role of physical activity in preventing common chronic diseases already in childhood


Once again on publication from my PhD student and from the PANIC Study, which 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.
