NEW figures have revealed that more than a third of North Yorkshire residents are risking major health problems by not exercising enough.

The study, by MORI and Sheffield Hallam University, found only 26 per cent of people living in the county exercise for at least 30 minutes, five or more times a week.

A further 37 per cent take part in sport or active recreation four or fewer times a week.

But 36 per cent are said to be inactive, exercising less than once a week.

Michelle Hanchard, Hambleton and Richmondshire Primary Care Trust's specialist in health improvement, said the third of North Yorkshire residents who did not exercise enough, faced an increased risk of developing chronic diseases such as heart disease, stroke, type two diabetes and cancer.

Ms Hanchard added: "Low levels of physical activity have also contributed to the dramatic increase in the levels of obesity we are observing in this country.

"Regular physical activity also reduces the risk of depression and has positive benefits for mood and self-esteem."

The Sport England-funded study was conducted for all of Yorkshire and Humberside.

North Yorkshire's district and borough councils said yesterday they were working hard to increase participation in sport.

Hilary Conway, community leisure officer for Richmondshire District Council, said: "As a council, we are aiming to ensure that everyone is as healthy as possible and that everyone has access to a wide range of cultural, leisure and sporting facilities.

"During this financial year, the council has allocated funding to two multi-use games areas which will be constructed in Middleton Tyas and Askrigg.

"The facilities will provide residents with access to an area for both organised and casual sport with reduced travel."

David Gent, regional director of Sport England Yorkshire, said: "The Yorkshire Plan for Sport aims to increase participation in sport and active recreation by four per cent by 2008.

He said the new information provided detailed knowledge that meant that money and time can be invested in sport and physical activity in the communities that need it most.
