Pediatrics Why Is Scoliosis More Common In Girls Than Boys? By Pediatrics, May 19, 2017 Your brown eyes, red hair, and the shape of your nose — all traits you can inherit from your mother and father. On the other hand, how someone develops scoliosis, and why it is more common among women than men, remains more of a mystery. Scoliosis is a disorder that causes your spine to curve in the shape of a “C” or an “S.” Idiopathic scoliosis is a specific type of scoliosis that develops for unknown reasons. Spinal curvature due to scoliosis can range from mild to severe. Learn more from the Spine Center at Children’s Hospital of Pittsburgh of UPMC What Causes Scoliosis? Doctors do not know why some people are more likely to develop scoliosis than others. They also do not fully understand why girls suffer from the condition more than boys. Factors such as family history may or may not contribute to a child developing scoliosis. Doctors do believe genetics play a role in the development of this condition. RELATED: Scoliosis Frequently Asked Questions Scoliosis typically appears before or during puberty. Major growth spurts that occur right before puberty might be related to scoliosis. Girls who are taller than other children their age also have an increased risk for scoliosis. The hormone leptin may also be linked to scoliosis. Leptin tells your brain when you are full, and affects the activity of your Sympathetic Nervous System (SNS). Studies found girls who have higher amounts of both this hormone and SNS activity are more likely to have scoliosis. If you suspect your child may have scoliosis, contact the Children‘s Hospital of Pittsburgh Department of Orthopaedics for more information about receiving a diagnosis and treatment options. Scoliosis in Girls Even though we may not know why scoliosis develops, we do know scoliosis occurs more frequently in females than males. According to the American Academy of Orthopaedic Surgeons, idiopathic scoliosis occurs ten times more often in girls than it does in boys over the age of 10. Another group of doctors at Indiana University Health revealed 10 percent of women in the US have scoliosis compared to only 5 percent of men. Not only are girls more likely to develop scoliosis, but they are also more likely to develop severe curves from the disorder as well. When a girl receives a diagnosis of scoliosis, the chance of her curve worsening is up to eight times more likely than in a boy of similar age.
