Chronic Childhood Conditions Associated with Low Vitamin D

Among these common chronic health problems, the following have well-established or emerging associations with low vitamin D:

Chronic Condition Low Vitamin D Evidence/Notes
Asthma Yes Low vitamin D is linked to increased asthma severity and exacerbations[6][10][16].
Type 1 Diabetes Yes Vitamin D deficiency is more common in children with type 1 diabetes and may impact immune function[10][16].
Cystic Fibrosis Yes Malabsorption leads to high risk of vitamin D deficiency, affecting bone health[8][10].
Juvenile Arthritis Yes Children with chronic inflammatory conditions have higher risk of vitamin D deficiency[10][16].
Epilepsy Yes Some antiepileptic drugs reduce vitamin D levels, increasing risk of deficiency and bone disease[10].
Obesity Yes Obese children are at higher risk for vitamin D deficiency due to sequestration in adipose tissue[6][10].
Malnutrition Yes Inadequate dietary intake can directly cause vitamin D deficiency[10][7]

         

Other conditions such as ADHD, chronic sinusitis, chronic ear infections, rheumatic heart disease, and hypertension do not have a strong or direct association with vitamin D deficiency based on current evidence.

Additional Notes

  • Vitamin D deficiency is particularly prevalent in children with chronic systemic diseases affecting the gastrointestinal, renal, liver, neurologic, and musculoskeletal systems, often due to malabsorption, limited sun exposure, or medication side effects[10][8].

  • Children with chronic illnesses are at increased risk for poor bone health due to both their underlying disease and the higher likelihood of vitamin D deficiency[10].

  • Symptoms of vitamin D deficiency in children can be subtle and may overlap with symptoms of chronic illness, making proactive screening important in high-risk groups[6][10].

    • In summary:** Of the top 10 chronic health problems in children, asthma, type 1 diabetes, cystic fibrosis, juvenile arthritis, epilepsy, obesity, and malnutrition are most strongly associated with low vitamin D[6][8][10][16].
