The low level of physical activity among children and young people in Northern Ireland has been described as a major health concern .
The warning is contained in a research paper on their physical activity and wellbeing just published by the Northern Ireland Assembly.
It said that more than a quarter of children in Northern Ireland were classed as overweight or obese.
The research paper was written for Stormont s Education Committee.
It said several studies suggested that physical activity, particularly at school, could improve children s mental as well as physical health.
