Low physical activity in youth is associated with brain cancer
According to a study by the National Cancer Institute of the United States published in the journal Cancer Research., Glioma, a form of cancer fatal brain in most cases, would be closely linked to physical activity that takes place during adolescence .
According to what explained the study leader Steven C. Moore, investigations resulted that there are biological factors associated with both the growth during adolescence and the expenditure of energy and both have an important role in the development of glioma.
This indication would help understand the biology of glioma and may be modified as the lifestyle factors to prevent disease.
Little is known about although gliomas are the most common type of brain cancer. However, with this research as evidence emerged that environmental exposures during childhood and both adolescence have an important role in the origin of this type of disease.
Physical activity, the rate of body mass and height were used as parameters to determine if these factors early in life could be associated with risk of glioma.
Between 1995 and 1996 nearly 500,000 men and women participating in a study on diet and health , completed a questionnaire about their lifestyle and feeding are subsequently followed up participants for 8 years and the result was that 480 of them suffered from glioma.
The conclusion reached was that those who remained physically active in adolescence had a lower risk of glioma, about 36%, compared with those who were inactive at the same stage of life and those who were obese adolescence were at greater risk for this disease.
On the other hand, it was concluded that taller people have twice the risk of breast cancer, but neither physical activity nor obesity in adults may be associated with the disease.
The researchers believe that these studies should be extended to confirm the association of glioma with obesity, since in this research the number of obese participants was very low.
