Analysis of Serum Fat-soluble Vitamin Levels in Infants and Children in Anning City
-
摘要:
目的 了解安宁市婴幼儿及儿童血清脂溶性维生素水平,为安宁市儿童合理补充脂溶性维生素提供参考。 方法 于2019年6月至2020年7月,选取昆钢医院儿童体检中心925名婴幼儿及儿童,使用高效液相色谱-串联质谱法(HPLC-MS/MS)定量检测血清中脂溶性维生素;根据不同年龄、性别和季节进行脂溶性维生素营养水平分析。 结果 925例婴幼儿及儿童血清维生素A、25-羟基维生素D3、维生素E和维生素K的平均水平及不足和缺乏率分别为:(284±3.84)ng/mL,61.08%(565/925);(34.27±0.46)ng/mL,1.73%(16/925);(8.47±0.16)μg/mL,12.11%(112/925);(0.46±0.03)ng/mL,19.68%(182/925)。不同年龄段(3岁以下,4~6岁,7~12岁)之间及不同季节之间脂溶性维生素水平,差异有统计学意义(P < 0.01)。 结论 安宁市婴幼儿及儿童维生素A严重缺乏,需要密切关注,合理补充。由于天然的日照优势,维生素D营养水平较好,因避免盲目过度补充。 Abstract:Objective To investigate the serum fat-soluble vitamins levels in infants and children in Anning City, to provide reference data for reasonable fat-soluble vitamin supplementation. Methods From June 2019 to July 2020, 925 infants and children from Children’ s Physical Examination Center of Kungang Hospital were selected. High performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used to test the serum fat-soluble vitamins quantitatively. Then the fat-soluble vitamins levels were analyzed based on different ages, genders, and seasons. Results The average levels as well as insufficiency and deficient rates of serum vitamin A, 25-hydroxyvitamin D3, vitamin E and vitamin K in 925 infants and children were (284±3.84) ng/mL, 61.08%(565/925); (34.27±0.46)ng/mL, 1.73%(16/925); (8.47±0.16)μg/mL, 12.11%(112/925) and (0.46±0.03)ng/mL, 19.68%(182/925), respectively. There were differences between different age groups (age range 0-3, 4-6, 7-12) and seasons (P < 0.01). Conclusion There was a serious deficiency of vitamin A, which requires close attention and reasonable supplement. Due to the natural sunshine advantage in Yunnan, vitamin D nutrition level is relatively good, and excessive supplementation should be avoided. -
