摘　　要：目的 了解合肥市8 - 10岁儿童甲状腺容积大小，并探讨其影响因素。方法 2016年，按照《全国碘缺乏病监测方案（2016版）》要求，采用分层多阶段抽样方法，在合肥市所辖9个县（市、区）内按照东、西、南、北、中5个方位各抽取1所小学，在抽中的每所小学中抽取40名8 - 10岁儿童（男女各半、年龄分布均衡），进行甲状腺容积、身高和体质量测量；同期进行问卷调查，问卷项目包括性格、学习压力、膳食习惯、相关疾病史和接触史等。结果 在合肥市辖内9个县（市、区）共抽取45所小学、1 800名8 - 10岁儿童，儿童甲状腺容积为（3.009 ± 1.197）ml；共发现甲状腺肿大71例，甲状腺肿大率为3.9%，达到碘缺乏病消除标准（ 〈 5%）。单因素分析显示，不同年龄组、食用海带和紫菜不同频次、是否接受放射检查以及不同身高和体质量的8 - 10岁儿童，其甲状腺容积比较差异有统计学意义（P均 〈 0.05）；多元线性回归分析表明，体质量、身高是影响合肥市8 - 10岁儿童甲状腺容积的主要因素，标准偏回归系数分别为0.288和0.140。结论 合肥市8 - 10岁儿童甲状腺容积总体处于正常水平，甲状腺肿大率低于碘缺乏病消除标准。在评价学龄儿童甲状腺容积大小时除分析年龄因素外，还应综合身高、体质量等其他因素的影响。Objective To investigate the status and the influencing factors of thyroid volume of children aged 8 - 10 years in Hefei City. Methods In 2016, according to the requirements of ＂National Iodine Deficiency Disorders Surveillance Plan （the 2016 Edition）＂, the method of multistage stratified sampling was used in 9 counties（cities, districts） of Hefei. Five primary schools were randomly selected from each county （city, district）, with one in each direction （the east, west, south, north and center）, then 40 children aged 8 - 10 years （male ∶ female = 1 ∶ 1, with similar age distribution） were randomly chosen in each primary school. The thyroid volume, height and weight were measured. In addition, a questionnaire with the items including personality, learning pressure, dietary habits, related disease history and contact history was designed and used to collect the data of the subjects. Results Totally 1 800 children aged 8 - 10 years were selected from 45 primary schools in 9 counties （cities, districts）. The mean thyroid volume was （3.009 ± 1.197） ml. Totally 71 people were found with thyroid enlargement and the goiter rate was 3.9%, which was in the range described in the elimination iodine deficiency disorders （IDD） standard （ 〈 5%）. Univariate analysis showed that for children in different age groups, seafood consumption frequency, radiological examination, height, and body mass, the thyroid volumes were significantly different （P 〈 0.05）; Multivariate linear regression showed that body weight and height were main factors affecting the thyroid volume of children aged 8 - 10 years in Hefei City, the standard partial regression coefficient are 0.288 and 0.140, respectively. Conclusions The thyroid volume of the 8 - 10 years old children is generally in the normal range in Hefei. Goiter rate is lower than the standard for elimination of iodine deficiency The findings have showed that not only age, but also height, body mass and other factors should be considered whi
