Vitamin D Deficiency
Conditions
Brief summary
Vitamin D plays an important role in phosphocalcic metabolism and bone homeostasis in newborns. Premature newborns are at risk of vitamin D deficiency and may require supplementation. In this context, the French Society of Pediatrics (Société Française de Pédiatrie) recommends systematic vitamin D testing at 1 month. The aim of this study was to determine the frequency of vitamin D deficiency in premature newborns.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Vitamine D deficiency frequency | 6 months | 25-OH Vitamine D values will be collected for premature newborn , born before 32 weeks, or with a birth weight under 1500g. A 25-OH Vitamine D blood value under 20µg/L is considered as a vitamine D deficiency |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| vitamine D deficiency and maternal or feotal caracteristics | 6months | correlation between vitamine D deficiency and maternal or feotal caracteristics |
| vitamine D deficiency and premature newborn comorbidities | 6 months | correlation between vitamine D deficiency and premature newborn comorbidities |
| effect of supplementation | 6months | Number (proportion) of children with normalized 25 OH vitamin D levels after Vitamine D supplementation according to neonatal department protocol. |
