Background: In recent years, vitamin D is attracting increasing interest due to the resurgence of vitamin D deficiency and rickets in developed countries, identifying their extraesqueletics actions and greater understanding of its many benefits. Vitamin D deficiency in children prevalence of vitamin D deficiency in certain regions described up to 80%, especially at high latitudes (above 37) and some breeds.

Objective and hypotheses: To study the degree of deficit VITD in our population (Location: 42° 51’ north latitude 2° 41’ west longitude) and check whether there are ethnic differences.

Method: Cross-sectional observational study. Inclusion: Patients historical Endocrinology Unit Child-up over 2014. 1 wave/semester. Rating ethnic and outdoors origin. Excluded: Children with chronic disease and unable to fulfill. Reference Endocrine Society (2011) Levels of 25-OH-vitamin D (ng/ml), failure <30. Control performed within their own routine monitoring base. Study test (X2) and ANOVA, with a confidence interval of 95%. SPSS 19.0.

Results: 152 cases initially selected (72/152♂–47%). Average age 9.24aDS3.27 (1–15). Pubertal (92/152) 60%. Distribution pathology (DM 36/152, 34/152 size, thyroiditis 15/152, forward/precocious puberty 23/152, 41/152 overweight, others 2/152). Distribution by ethnicity (Caucasian 108/152, black 8/152, 10/152 Maghreb, latina oriental 2/152 24/152). 35/42/28/47 quarterly distribution. No sex differences, pubertal status and pathology in the waves.78% in range 25OHD insufficiency average 21 ngr/ml DS (12–29). Significant differences between quarters (P: 0.01) and etnarios groups (P:0.001). Caucasian children deficit 68% (73/108) 25OHD average 24 ngr/ml DS (18–29) compared with 95% of foreign (42/45) 25OHD average of 12 ngr/ml DS (2–25), group deficit more severe. 1 case of tetanus hypocalcaemia.

Conclusion: Children in our region have a prevalence of vitamin D deficit. Important. The exercise outdoors, extracurricular activities and a clearer skin could be responsible for the differences found, but given the high prevalence should make a general recommendation for prophylaxis VITD all the paediatric population in our latitude during school months.
