What leading factor contributes to the increase in Rickets cases among children today?

The increase in cases of Rickets among children can be largely attributed to spending less time outdoors. Rickets is primarily caused by a deficiency of vitamin D, which is essential for the absorption of calcium and phosphate in the body. Vitamin D is synthesized in the skin in response to sunlight exposure.

When children spend less time outdoors, they receive less sunlight, which leads to lower levels of vitamin D. This deficiency can result in weakened bones and can manifest as Rickets.

In contrast, increased outdoor activities would typically lead to more sun exposure, potentially increasing vitamin D levels and reducing the risk of Rickets. Excessive dairy consumption is not a leading factor related to Rickets; while dairy products are a source of calcium and other nutrients, they do not directly influence vitamin D synthesis. Similarly, although a lack of physical exercise can affect overall health, it is not a primary contributing factor to the rise in Rickets cases. The key issue remains the limited outdoor sunlight exposure, which directly impacts vitamin D production.
