摘　　要：目的了解福州市8~10岁儿童碘营养状况,并探讨儿童甲状腺容积与体格发育指标的关系.方法采用多阶段分层抽样,2020年4月-2022年4月每年在福州市所辖12个县(市)区按东、西、南、北、中5个方位各随机抽取1个乡镇/街道的1所小学,每所小学抽取8~10岁非寄宿学生40人,采集儿童即时尿样进行尿碘检测,使用B超法测量甲状腺容积,测量儿童身高、体重,并对儿童体格发育指数与甲状腺容积的关系进行分析.结果2020-2022年累计调查8~10岁儿童7390人.尿碘中位数为174.30µg/L.共检查7390名儿童甲状腺,甲状腺肿大79例,甲肿率1.07%.儿童甲状腺容积范围为0.6~16.5 ml,中位数2.51 ml.8~10岁儿童甲状腺容积与体表面积、身高、体重、年龄及身体质量指数均成正相关.多重回归分析结果显示体表面积对甲状腺容积影响大于年龄.结论福州市学龄儿童碘营养状况适宜,甲状腺容积随年龄、体格发育的增大而增大.Objective To investigate the iodine nutrition status of children aged 8-10 years in Fuzhou city,and to explore the relationship between thyroid volume and physical development indexes in children.Methods Multi-stage stratified sampling was adopted.From April 2020 to April 2022,a primary school in a township/street in 12 counties(cities)of Fuzhou was randomly selected from the east,west,south,north,and middle directions each year,and 40 non-boarding students aged 8-10 years were selected from each primary school.Instant urine samples were collected for urine iodine detection,and thyroid volume was measured by B-ultrasound.The height and weight of children were measured,and the relationship between children's physical development indexes and thyroid volume was analyzed.Results A total of 7390 children aged 8-10 years were investigated from 2020 to 2022.The median urinary iodine was 174.30µg/L.A total of 7390 children were examined for thyroid gland.About 79 goiter cases were found,and the rate of goiter was 1.07%.The thyroid volume of children ranged from 0.6 to 16.5ml,with a median of 2.51ml.Thyroid volume was positively correlated with body surface area,height,weight,age,and body mass index in children aged 8-10 years.The multiple regression analysis showed that the influence of body surface area on thyroid volume was higher than that of age.Conclusion The iodine nutritional status of school-aged children in Fuzhou is suitable,and the thyroid volume increases with the increase of age and physical development.
