What deficiency is primarily associated with rickets in children?

Rickets in children is primarily associated with a deficiency of Vitamin D. This vitamin is crucial for the proper absorption of calcium and phosphorus in the body, which are essential minerals for healthy bone development. When there is insufficient Vitamin D, the body cannot absorb these minerals effectively, leading to weakened bones and the classic symptoms of rickets, such as bone pain, delayed growth, and deformities.

In children, if Vitamin D levels are low due to inadequate dietary intake, insufficient sunlight exposure, or certain medical conditions, it can lead to significant health issues, particularly with bone mineralization. Thus, ensuring adequate Vitamin D intake is vital for preventing rickets and promoting skeletal health in growing children.
