Osteogenesis Imperfecta - Epidemiology

Epidemiology

In the United States, the incidence of osteogenesis imperfecta is estimated to be 1 per 20,000 live births. An estimated 20,000 to 50,000 people are affected by OI in the United States.

Frequency is approximately the same across groups, but for unknown reasons the Shona and Ndebele of Zimbabwe seem to have a higher proportion of Type III to Type I than other groups. However, a similar pattern was found in segments of the Nigerian and South African population. In these varied cases the total number of OIs of all four types was roughly the same as any other ethnicity.
