World Osteoporosis Day: October 20,2011

Wake-up call on weak bones
NEW DELHI: Here is something that should send couch potatoes among girls to the running track. A study has established the link between loss of bone density and a sedentary life. The study conducted on 186 girls from Delhi University - including those who are into sports - shows that only 1% of non-sportswomen meet the recommended dietary allowance for calcium, a major factor for bone strength.

Their exposure to sunlight is also less than required, putting them at higher risk for bone loss after they turn 50. On World Osteoporosis Day, being observed on Thursday, doctors advise that girls should exercise more and eat healthy during adolescence because that is the time when bones develop. Decline in bone strength starts after age 30. "Approximately 40% of bone acquisition takes place during adolescence, which protects against post-menopausal osteoporosis or bone loss. Our study highlights the need for girls to indulge in physical activity and focus on a healthy diet during this period so that they develop strong bones.

Fragility fractures in women and bone loss is common these days," said Dr Nikhil Tandon, professor endocrinology and metabolism at AIIMS, who headed the study. Institute of Nuclear Medicine and Allied Sciences, and Institute of Home Economics, DU, also participated in the study.
