About 1 in 100 (1%) of the general population has some type of
scoliosis.1 Fortunately, most
cases of scoliosis are mild.
Scoliosis usually starts between the ages of 8 and 10.2
Scoliosis that is bad enough to need treatment is most common in girls.3 The prevalence of scoliosis in female athletes may be even
higher because they are at increased risk for muscle pain (nonstructural
scoliosis) or spinal injury (structural scoliosis).4
Girls are seven times more likely than boys to have a significant curve that
requires treatment.3
Mild or small curves are more common than moderate or severe curves.
For example, about 0.2% of people with scoliosis have a curve of more than 30
degrees, and about 0.1% of people with scoliosis have a curve of more than 40
degrees. About 10% of children who are diagnosed with scoliosis require
treatment (either bracing or surgery).5
Of those with scoliosis, 30% have family members with the
condition.2 Children—especially daughters—of women who
have scoliosis are at increased risk for having scoliosis.1
