Fractures of the hip and distal forearm in West Africa and the United Kingdom.
Adebajo AO., Cooper C., Evans JG.
Comparison of age- and sex-specific incidence rates of fractures of the proximal femur and the distal forearm showed significantly lower rates in Ibadan than in two urban centres in England, with risk ratio of up to 20. In the Ibadan data no evidence of higher rates in women or of a prominent age-associated increase in rates was observed.
