Non modifiable risk factors
Genetic factors account for up to 80% of the difference in peak bone mass and bone turnover, as well as contributing to the occurrence of osteoporotic fractures.
Bone mineral density decreases with age and therefore the risk of osteoporosis increases.
Ethnicity: Afro-Caribbean women have a higher bone mineral density than Caucasian women and this factor is at any given age be it in adolescent or adulthood. They also have a higher peak bone mineral density and they lose the bone at a slower rate.
History of previous fracture: women who have had a fragility fracture are at increased risk of future fractures irrespective of bone mineral density.
