　　目的了解广西学龄儿童维生素D营养状况与生长发育关系，为防治儿童维生素D缺乏提供科学依据。方法采用横断面研究的方法，随机选取广西融水县512名6～13岁儿童，采集静脉血，用酶联免疫吸附法测定血清25-羟维生素D[25-(OH)D]浓度，测量身高、体重，计算体质指数（BMI）。结果研究对象血清25-(OH)D平均浓度为（22.86±0.41）ng/mL。血清25-(OH)D浓度与性别、身高、体重、BMI呈正相关（R2=0.046，P＜0.05）。研究对象血清25-（OH）D水平各年龄组间差异有统计学意义（F=2.382,P＜0.05）。各年龄段维生素D营养状况分布不同，13岁组血清25-(OH)D水平处于正常或充足状态的比例最高，占33.30%；而7岁组最低仅占3.20%，8～9岁组血清25-(OH)D缺乏者较多，分别占61.90%和44.70%。结论维生素D营养状况与学龄儿童BMI呈正相关，维生素D缺乏状况不容忽视。

Objective To assess the relation between vitamin D status and growth in school children in Guangxi, and provide scientific evidence for preventing vitamin D deficiency symptom. Methods In a cross-sectional study, 512 children aged from 6 to 13 years were randomly recruited in Rongshui County. The concentration of 25-hydroxyvitamin D [25-(OH)D] in the blood Sample from students was determined by ELISA. Height, weight and BMI in school students were measured. Results The average serum 25-(OH)D concentration was (22.86±0.41) ng/mL. Serum 25-(OH)D concentration was significantly correlated with sex, height, weight as well as BMI(R2=0.046,P<0.05). There was statistically significant difference in the serum level of 25-(OH)D among the children at different age groups (F=2.382,P<0.05); the sufficient rate of vitamin D in 13-years old group was the highest(33.3%), and the sufficient rate of vitamin D,but in 7-years old group was the lowest(3.2%);the deficiency rate of vitamin D in 8 and 9-years old group was the highest(61.9%and 44.7%respectively). Conclusion Vitamin D had positive effect on BMI, and it is important not to occur the vitamin D deficiency symptom.
