摘要
目的分析2020年南宁市碘缺乏病监测结果,掌握居民碘盐食用情况及重点人群碘营养状况,为针对性制定或调整碘缺乏病防治措施提供科学依据。方法按照《广西壮族自治区碘缺乏病监测方案》,在南宁市所辖12个区(县)开展监测,每个区(县)按东、西、南、北、中5个方位各抽取1个乡镇(街道),每个乡镇(街道)抽取40名8~10岁非寄宿儿童和20名孕妇作为监测对象。采集儿童随机中段尿样、孕妇晨尿及家中食盐盐样分别检测尿碘和盐碘含量;对青秀区、良庆区、隆安县和上林县8~10岁儿童进行甲状腺检查,计算甲状腺肿大率。结果2020年南宁市共调查8~10岁儿童2434人、孕妇1207人,碘盐覆盖率、碘盐合格率、合格碘盐食用率分别为99.67%(3629/3641)、97.99%(3556/3629)、97.67%(3556/3641);儿童尿碘中位数为182.0μg/L,各区(县)中位数范围为146.5~234.8μg/L,城区与非城区,不同性别、年龄组尿碘中位数比较差异均有统计学意义(U=2.38、2.41,P=0.017,0.016;H=16.42,P<0.001);儿童甲状腺肿大率为0.99%(8/807),开展甲状腺检查的4个区(县)儿童甲状腺肿大率范围为0~2.00%(4/200),城区与非城区、不同年龄儿童甲状腺容积比较差异均有统计学意义(U=-3.52,P<0.001;H=47.67,P<0.001)。孕妇尿碘中位数为191.0μg/L,各区(县)中位数范围为141.0~241.5μg/L,不同孕期孕妇尿碘中位数比较差异有统计学意义(H=24.37,P<0.001)。结论2020年南宁市居民碘盐覆盖率、碘盐合格率、合格碘盐食用率均较高,儿童及孕妇碘营养均处于适宜水平。
Objective To analyze the monitoring results of iodine deficiency disorders in Nanning City in 2020,learn about the consumption of iodized salt among residents and the iodine nutrition status of key populations,and provide scientific basis for formulating or adjusting targeted prevention and control measures of iodine deficiency disorders.Methods According to the Guangxi Iodine Deficiency Disorders Monitoring Plan,monitoring was carried out in all of 12 districts(counties)in Nanning City.One township(street)was selected from each of the five directions of east,west,south,north,and central.Forty non-boarding children aged 8 to 10 and 20 pregnant women were selected as monitoring subjects in each township(street).Edible salt samples were collected from children and pregnant women to detect salt iodine content,random mid-course urine samples from children and morning urine samples from pregnant women were collected to detect urinary iodine content;in addition,thyroid examination of children was conducted in Qingxiu District,Liangqing District,Long an County and Shanglin County.Results In 2020,a total of 2434 children aged 8 to 10 and 1207 pregnant women were surveyed in Nanning City.The coverage rate of iodized salt,the qualified rate of iodized salt and the qualified iodine salt consumption rate were 99.67%(3629/3641),97.99%(3556/3629)and 97.67%(3556/3641),respectively.The median urinary iodine of children was 182.0μg/L,and the median values ranged from 146.5 to 234.8μg/L in different districts(counties),there were significant differences in median urinary iodine between urban and non-urban areas,different gender and age groups(U=2.38,2.41,P=0.017,0.016;H=16.42,P<0.001).The goiter rate of children was 0.99%(8/807),and the rate ranged from 0 to 2.00%(4/200)in the 4 districts(counties)examined,there were significant differences in thyroid volume between urban and non-urban areas and different ages(U=-3.52,P<0.001;H=47.67,P<0.001).The median urinary iodine of pregnant women was 191.0μg/L.The median urinary iodine of different districts(counties)ranged from 141.0 to 241.5μg/L,and the difference was statistically significant at different gestational stages(H=24.37,P<0.001).Conclusion In 2020,the coverage rate of iodized salt,the qualified rate of iodized salt and the qualified iodine salt consumption rate by residents in Nanning City are high,and the iodine nutrition of both children and pregnant women are at an appropriate level.
