The great challenge: bone fragility and environment.

Osteoporosis is a worldwide common disease characterised by reduced bone mass and increased risk of fractures.Many genetic variants are associated with the disease, but they account for only a small percentage of variance in individual bone mineral density and fragility fracture risk. Only recently have researchers recognised the role of a broad variety of environmental factors in the pathogenesis of osteoporosis, which has led to a further step: how genetic and environmental factors can interact, which is the next frontier in research on bone fragility.
