Answer

In the United States, the incidence of diskitis ranges from 1 in 100,000 population to 1 in 250,000 population. In other developed nations, the incidence of diskitis is similar; however, in less developed nations, infectious diskitis is much more common. In some areas of Africa, it has been reported that 11% of all patients seen for back pain were diagnosed with diskitis.

A bimodal distribution of ages occurs with diskitis. Childhood diskitis affects patients with a mean age of 7 years. The incidence of diskitis then decreases until middle age, when a second peak in incidence is observed at approximately 50 years of age. Some authors argue that childhood diskitis is a separate disease entity and should be considered independently.

The predominance of diskitis in males is more pronounced in adults, with male-to-female ratios ranging from 2:1 to as high as 5:1. Childhood diskitis has a slight male prevalence, with a male-to-female ratio of 1.4:1.

No specific racial predilection has been noted.
