【Abstract】 Objective To learn about the serum 25-hydroxyvitamin D level of 0 to 14-year-old children in Sanmenxia.Methods A total of 1 338 children were chosen, who were treated in Huanghe Sanmenxia Hospital from January 2017 to December 2017.The level of 25(OH)D was determined by high-performance liquid chromatography tandem mass spectrometry.Results The level of 25(0 H)D in 1 338 children was(28.17±11.89)μg/L,in which the appropriateness rate was 73.6%(985/1 338).With the increase of the age, the level of vitamin D had a decreasing tendency. The vitamin D level reached the highest level in summer, being(32.65±10.49)μg/L, and the lowest in winter, being(21.32±11.83)μg/L.Conclusion The level of serum 25(OH)D is good in children aged 0 to 14 years old in Sanmenxia area. The vitamin D level of children changes significantly with the age and season, so they should increase outdoor activities, and vitamin D should be supplemented scientifically and reasonably in accordance with the age and season.更多还原
