Video games increase the risk of osteoporosis in adolescent boys
Boys who spend more time in front of the TV or computer have lower bone density than girls or boys who spend quality time in nature, as new research reveals. This means that in later life they face an increased risk of fractures and osteoporosis.
The human skeleton grows continuously from birth to late adolescence, reaching peak bone mass -in terms of strength and size- in early adulthood. Along with nutritional factors, physical activity can greatly impact on this process.
According to the Norwegian study, sedentary lifestyles in teenagers affect bone health and obesity rates. The study examined 463 girls and 484 boys aged 15 to 18 years. Bone density was measured by DXA (dual-energy X-ray absorptiometry), while their lifestyles were determined through questionnaires and interviews.
The researchers found that boys spent more time in front of computers than girls. In contrast to the boys, girls who spent four to six hours in front of the computer, had higher bone density than counterparts who spent less than 1.5 hours in front of a screen each day.
The study was presented at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases, on the occasion of low levels of awareness about osteoporosis risk and bone health in men.
