目的:了解成都市儿童维生素D的营养状况。方法:对来医院儿童保健科门诊进行常规体检的0～6岁701例儿童采用酶联免疫法进行血清25-(OH)D检测。结果:25-(OH)D的平均测定值为(68.60±1.29)nmol/L,25-(OH)D缺乏及严重缺乏的为226例,占32.24%;25-(OH)D水平不足的为237例,占33.811%;水平充足(合适水平)的为238例,占33.95%,前两者占总人数的66.05%。男性和女性血清25-(OH)D水平差异无统计学意义(P>0.05),但25-(OH)D水平随着年龄增高而呈下降(P<0.01)。血清25-(OH)D水平夏秋季显著高于春冬季节(P<0.05)。结论:成都市0～6岁儿童25-(OH)D水平低下,应增加该地区儿童的维生素D摄入量及加强户外活动,尤需重视3～6岁的儿童及冬春季节维生素D的补充。
Objective: To understand the nutritional status of vitamin D in children in Chengdu. Methods: Serum 25- (OH) D was detected by enzyme-linked immunosorbent assay (ELISA) in 701 children aged 0-6 years. Results: The average measured value of 25- (OH) D was (68.60 ± 1.29) nmol / L, while the lack of 25- (OH) D and severe deficiency were 226 and 32.24%, respectively. 237 cases, accounting for 33.811%; adequate level (appropriate level) for 238 cases, accounting for 33.95%, the former two accounted for 66.05% of the total number. There was no significant difference in serum 25- (OH) D levels between men and women (P> 0.05), but the level of 25- (OH) D decreased with age (P <0.01). Serum 25- (OH) D levels in summer and autumn were significantly higher than those in spring and winter (P <0.05). Conclusion: The 25- (OH) D level of 0-6 year-old children in Chengdu is low. Children’s vitamin D intake and outdoor activities should be increased in this area, especially children aged 3 to 6 years and vitamin D in winter and spring supplement.
