  Knowledge of vitamin D has made great progress in recent years with the identification of its receptors (VDR) in most tissues, passing it from the role of a purely phosphocalcic and bone tropic hormone to that of a hormone playing a role global health.

  In Algeria, we lack epidemiological studies to assess the vitamin D status of healthy and supplemented infants. Through this work, we propose to determine the vitamin D status, to assess the vitamin D nutritional intake of healthy infants and to identify risk factors related to hypovitaminosis D in order to target and treat populations at risk.

Results: The analysis covers 395 infants aged between 9 and 24 months recruited during the 4 seasons. The mean age was

  11.5 ± 1.3 months. The sex ratio was 1.5. The average daily dietary intake of vitamin D was estimated at 167 IU/d (4.1µg/d). 90% of the children had low daily food intakes (less than 200IU/d).

The mean total vitamin D level in our series was 15.6 ± 4.4 ng/ml, significantly lower than current recommendations (25 OHD > 20 ng/ml) with a mean PTH level of 38 ± 4.2 pg/ml.

  The prevalence of vitamin D deficiency increased from 50% in the 12-24 month age group, to 75% in the 09-12 month group in winter, and from 21% in children aged between 12 and 24 months to 64% in children aged between 09.

  The risk of vitamin D deficiency is associated with individual factors that cannot be modified (skin pigmentation), lifestyle habits (lack of sunlight, insufficient dietary intake of vitamin D and) and environmental factors (season).

Conclusion: The magnitude of the prevalence of hypovitaminosis D in infants with high bone growth velocity and increased vitamin D requirements prompts us to question vitamin D drug supplementation. Six-monthly systematic vitamin D supplementation would be necessary for children with risk factors as well as children without risk factors in the winter period according to the results of our study.
