title: [Plasma 25-OH D deficiency in Maghrebian children more than 10 years of age immigrated to France].
abstract: From 1984 Feb 1st to April 30, 63 blood samples were collected from children more than 10 years old in the pediatric unit of CHR de St-Etienne, and analysed for 25 OH D, calcium, phosphate, magnesium and alkaline phosphatase serum concentrations. Mean 25 OH D is lower (22,6 nmol/1) in 26 migrant children (24 from Maghreb and 2 from Turkey) than in 37 European children (mean = 48,6 nmol/1; p less than 0,001). Serum concentration is under 10 nmol/1 in 3 of the 37 Europeans (8%), versus 13 of the 26 Maghrebians (50%). Mean alkaline phosphatase and phosphate are significantly higher in the 36 boys than in the 27 girls. A significative positive correlation is found between alkaline phosphatase and phosphate (r = 0,535; p less than 0,01). There is no relation between age, month of assessment, sex, height, weight, place of late holidays and any of the measured serum values.
