Factors that may increase a child's risk of rickets include:

  • Age. Children 3 to 36 months old are most at risk of rickets because their skeletons are growing so rapidly.
  • Dark skin. Dark skin doesn't react as strongly to sunshine as does lighter colored skin, so it produces less vitamin D.
  • Northern latitudes. Children who live in geographical locations where there is less sunshine are at higher risk of rickets.
  • Premature birth. Babies born before their due dates are more likely to develop rickets.
  • Anti-seizure medications. Certain types of anti-seizure medications appear to interfere with the body's ability to use vitamin D.
  • Exclusive breast-feeding. Breast milk doesn't contain enough vitamin D to prevent rickets. Babies who are exclusively breast-fed should receive vitamin D drops.
