摘　　要：目的调查深圳市宝安区0~12岁638名儿童维生素D(Vit D)水平,比较儿童超重/肥胖与Vit D营养状况之间的关系,整理反馈地区儿童Vit D水平状况,为妇幼保健机构和公共卫生组织制定儿童健康政策提供参考依据。方法收集本院健康体检儿童的年龄、性别、身高、体质量和既往病史等资料,用化学发光法检测血清中25-羟维生素D[25-(OH)D]含量,按相关参考标准计算研究样本的体质量指数(BMI)、超重/肥胖率以及Vit D营养状况并进行统计学分析。结果638名儿童样本中,血清25-(OH)D水平为(38.34±12.04)ng/ml。不同性别儿童血清25-(OH)D含量差异无统计学意义(P>0.05)。婴幼儿组血清25-(OH)D含量为(46.00±11.83)ng/ml,学龄前组为(36.00±3.51)ng/ml,学龄组为(30.47±8.19)ng/ml,不同年龄儿童血清25-(OH)D含量差异有统计学意义(P<0.05)。不同年龄组间Vit D营养状况差异有统计学意义(P<0.001),且Vit D缺乏及不足率为学龄组(101/176,57.39%)>学龄前组(60/215,27.91%)>婴幼儿组(11/247,4.45%)。超重/肥胖和正常组儿童血清25-(OH)D含量与BMI呈负相关,差异有统计学意义(P<0.05)。结论深圳宝安区学龄儿童Vit D缺乏及不足率较幼儿和学龄前儿童高,且超重/肥胖儿童多出现于学龄段;家长及学校应重视学龄儿童Vit D的有效补充,同时要谨防儿童超重及肥胖问题的发生。Objective To explore the level of vitamin D(Vit D)in children aged 0-12 at Bao'an,Shenzhen and the relationship between overweight/obesity and Vit D nutritional status in children,and to provide scientific references for making child health policies by regional maternal and child health institutions.Methods A cross-sectional study was used to collect the physical examination data of healthy children in the Maternal and Child Care Service Centre in Bao'an,including their ages,gender,heights,weights,and case history.The serum level of 25-hydroxy vitamin D[25-(OH)D]was measured by chemiluminescence.And the body mass index(BMI),overweight/obesity rate,and Vit D nutritional status were statistically analyzed according to the established criteria.Results The average serum 25-(OH)D level was(38.34±12.04)ng/ml in the 638 children.There was no statistical difference in serum 25-(OH)D level between the male and female children(P>0.05).The serum level of 25-(OH)D was(46.00±11.83)ng/ml in the baby group,was(36.00±3.51)ng/ml in the preschool children,and was(30.47±8.19)ng/ml in the school-age children,with statistical differences between the 3 groups(P<0.05).There were statistical differences in the Vit D nutritional status between the children of different ages(P<0.001).The Vit Ddeficiency and insufficiency ratewas 57.39%(101/176)in the school-age children,27.91%(60/215)in the preschool children,and 4.45%(11/247)in the baby group.The serum 25-(OH)D levels were negatively correlated with BMI in the overweight/obesity and normal children.Conclusions The deficiency and insufficiency rate of Vit D in school-age children at Bao'an is higher than those in infants and preschool children.Society,schools,and parents should pay more attention to the nutritional status of Vit D in school-age children.
