Type 1 Diabetes
Attention-Deficit/Hyperactivity Disorder (ADHD)
Cystic Fibrosis
Juvenile Arthritis
Epilepsy
Chronic Sinusitis

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].
