Injuries

• One reason diagnosing low bone density in children is so important is because of the potential risks involved. Children that have low bone density are more prone to fractures that can occur with very little trauma. Bones become weaker and can easily be injured when the density is at an unhealthy level.
  
  

Vitamin D Deficiency

• One of the most prominent causes of low bone density in children is a vitamin D defenciency. Children need lots of vitamin D and calcium to grow healthy bones and when they lack these essential vitamins and minerals, their bones suffer. Sunlight is also a source of vitamin D and children with darker skin have an increased risk of vitamin D defeciency because the higher levels of melanin in their skin blocks the sunlight needed for the synthesis of vitamin D. A nutritious diet rich in calcium and vitamin D coupled with sunlight is one solution to a low bone density problem.
  
  

Fibrous Dysplasia

• According to the Mayo Clinic, there are times when low bone density is the result of a bone disorder. For example, fibrous dysplasia is a condition that causes scar-like tissue to develop in the place of normal bone. The cause of fibrous dysplasia remains unknown and there is currently no cure for the disorder. Children with fibrous dysplasia are born with the disorder and in serious cases will see symptoms before age 15.
  
  

Exercise and Diet

• Researchers at the University of Wales and the University of Exeter suggested that children with low bone density combine vigorous exercise with a diet high in calcium. Vigorous activity includes normal playtime activities like jumping rope, running, or playing around outside with a ball. A combination of activity and high calcium intake is the key to an increase in bone density.
  
  

Considerations

• Through a simple x-ray, doctors can identify if a child has bones that look thin. It's important that low bone density is treated because if it is not, possible bone deformities can result. Taking the right preventative measures such as emphasizing a nutritious diet and lots of activity can help a child lower their risk of having low bone density.
