摘要
目的分析深圳市华龙新区0~6岁儿童维生素D的营养状况及其与身高发育的关系。方法 2016年1-12月对龙华新区的1 286例学龄前儿童进行一般人口学资料调查、体格检查以及维生素D水平的检测。根据年龄不同将研究对象分为出生后1个月~1岁(婴儿组)382名,>1~3岁(幼儿组)337名,>3~6岁(学龄前期组)567名。总结其总体维生素D营养状况、年龄特点、季节特点以及与身高发育的关系。结果不同年龄段的平均身高存在差异,均达到全国标准,血清25(OH)D的平均值为(35.37±10.81)nmol/L;随着年龄的增长,不同年龄段儿童的维生素D水平显著下降,差异有统计学意义(F=190.06,P=0.00)。学龄前期儿童的维生素D缺乏比例较高为53.62%。在季节方面,在6-8月检测时,儿童的血清25(OH)D平均值最高,均≥40 nmol/L。相关性分析结果显示,儿童的维生素D水平对其身高发育具有正向影响作用(r=0.622,P=0.018)。结论 2016年深圳市龙华新区0~6岁儿童的平均维生素D水平和平均身高基本达标,但维生素D缺乏的情况仍大量存在。因此,相关卫生部门及家长应该重视该情况,并根据维生素D水平的季节化和年龄化的特点采取有针对性的措施促进该地区的儿童进行维生素D的补充。
Objective To analyze the status of vitamin D nutrition and its relationship with height development among children aged 0-6 years in Longhua New District of Shenzhen City. Methods General demographic survey, physical examination and serum vitamin D detection were performed in 1,286 preschoolers in Longhua New District from January to December in 2016. Ac- cording to the age, the objects were divided into the baby group aged 1 month - 1 year （ n = 382 ） , the infant group aged 〉 1 - 3 years （ n = 337 ） and the preschool group aged 〉 3 - 6 years （ n = 567 ）. The general nutritional status of vitamin D, age characteris- tics, seasonal characteristics and the relationship between vitamin D status and height development were summarized. Results The average height of different age groups was diverse, and all met the national standard. The average level of serum 25 （ OH ） D was（ 35.37±10.81） nmol/L. With the increase of age, the serum vitamin D level decreased significantly, and the differences were statistically significant （F= 190.06, P= 0.00）. The percentage of vitamin D deficiency in the preschool group was relatively high （ 53.62% ）. As for the seasonal distribution, the average value of serum 25 （OH） D reached the highest （ all ≥40 nmol/L） from June to August. Correlation analysis showed that the serum vitamin D level had a positive effect on the height of children. Conclu- sions The average vitamin D level and height of the children aged 0-6 years in Longhua New District of Shenzhen City in 2016 were basically up to standard, but vitamin D deficiency still prevailed. Thus the relevant health departments and parents should pay more attention to the situation, and take targeted measures based on seasonal and age characteristics of serum vitamin D levels to promote vitamin D supplement among the children.
