Body vitamin D content and its relationship with body composition of children in Huairou district of Beijing

• OBJECTIVE: To analyze vitamin D concentration and its association with body composition of children in Huairou district of Beijing, to provide evidence for evaluation and improvement of nutritional status of vitamin D in children. METHODS: Totally, 381 children aged 7 - 11 years were recruited in Huairou district of Beijing (40.3 degrees N). Samples of overnight fasting venous blood (drawn between 0630 and 0900) were obtained in late March. Serum 25-hydroxyvitamin D [25(OH)D]concentration was determined by ELISA kits (IDS Ltd, UK). Body composition indices of the whole body, the distal and proximal forearm were measured using dual-energy X-ray absorptiometry (DEXA, Norland, USA). RESULTS: The average serum 25(OH)D concentration of all subjects was (44.4 +/- 12.5) nmol/L. The percentage of vitamin D insufficient [serum 25(OH)D
