Vitamin D deficiency is a common concern for kids of all ages and can cause various health problems. This deficiency occurs when the body doesn’t get enough of this important vitamin. Hence, it’s important to understand what brings about this deficiency, recognize the warning signs, and take preventive measures to ensure that it doesn’t happen in the first place.

Importance Of Vitamin D

Vitamin D plays a vital role in many important bodily functions, such as maintaining bone strength and enhancing immunity. It helps in the absorption of calcium from food and also helps maintain the right balance of calcium and phosphorus in the bones. Furthermore, maintaining optimal vitamin D levels in children may protect against certain autoimmune conditions, infections, and even type 2 diabetes (1).

What Causes Vitamin D Deficiency In Children?

In children, insufficient vitamin D levels can be attributed to various factors, including (2):

  • Inadequate Sun Exposure: Primarily, vitamin D is synthesized from sunlight. If children have limited outdoor exposure or reside in regions with scarce sunlight, it can lead to a deficit.

  • Not Eating Enough Vitamin D Foods: Insufficient consumption of vitamin D-rich foods like fatty fish, egg yolks, and fortified milk can result in deficiency.

  • Being Obese: When children have too much body fat, it can trap vitamin D since it’s fat-soluble. This makes it less available for the body to use.

  • Medical Conditions: Celiac disease, Crohn’s disease, Cystic fibrosis, and liver and kidney diseases are a few medical conditions that can cause vitamin D deficiency by affecting how the body absorbs or uses vitamin D.

  • Medications: Medications that can cause vitamin D deficiency include laxatives, steroids, Rifampin, and Orlistat. These medications can interfere with how the body handles vitamin D.

  • Weight-loss surgeries: Procedures that reduce the size of the stomach or intestines, often used for weight loss, make it harder for the body to absorb vitamin D.

Vitamin D Deficiency In India

Vitamin D deficiency is a widespread concern in India, affecting people of all ages due to dietary limitations and limited sun exposure. Studies indicate that a substantial portion of the population, up to 70% to 100%, lacks sufficient vitamin D (7). Notably, this deficiency extends to children living in both urban and rural areas, regardless of their socioeconomic status. Recent research reveals that approximately 13.7% of preschoolers, 18.2% of school-age children, and 23.9% of teenagers in India have inadequate levels of vitamin D (8).

As parents, being vigilant about spotting the early signs of vitamin D deficiency in our children and taking steps to prevent it can make a world of difference in their health and happiness. This means making sure your child eats a balanced diet, gets enough sunshine, and keeps up with regular doctor visits to maintain those essential vitamin D levels. So, let’s remember, a little knowledge and looking after our kids can go a long way in keeping them healthy and happy.
