Summary

Osteoporotic fractures are common, especially in women, and are associated with a substantial health, social and economic burden worldwide. Although age-specific rates are falling in most areas, shifts in population demographics are causing fracture numbers to continue to rise particularly in Asia and the developing world. There is a growing recognition of a complex interaction between genetic and environmental factors in the aetiology of osteoporosis. A substantial number of the genes identified as contributing to bone density influence one of three biological pathways: the oestrogen pathway, Wnt-β-catenin signalling pathway and the RANKL-RANK-OPG pathway. However, together these polymorphisms explain only a small proportion of the observed variance in bone density. Early life environment, such as intrauterine nutrition, also has an effect on adult bone health and is likely to act through alterations in gene expression and epigenetic mechanisms. This highlights a possible target for population-based interventions.
