目的分析化州市碘缺乏病监测结果,掌握化州市城乡居民碘营养状况和碘缺乏病病情,为制订有针对性的碘缺乏病防治措施提供科学依据。方法在化州市东、西、南、北、中5个方位各随机抽取1个乡镇/街道,在每个乡镇/街道各随机抽取4个行政村,每个行政村随机抽检15户居民家中食盐样品;在所抽取的乡镇随机抽1间小学,在小学中各随机抽取40名8~10周岁儿童,监测儿童尿碘含量和甲状腺肿大情况;在每个乡镇各随机抽检20名孕妇,监测孕妇尿碘含量和家庭食用盐样,对其中10名孕妇进行防治知识问卷调查。结果居民户合格碘盐食用率为97.33%,碘盐中位数为24.29 mg/kg,孕妇家庭碘盐中位数为23.90 mg/kg,居民户与孕妇家庭合格碘盐食用率差异无统计学意义(χ~2=0.46,P>0.05)。儿童尿碘中位数为195.00μg/L,5个乡镇学龄儿童的尿碘含量的分布不同,差异有统计学意义(H=10.44,P<0.05);孕妇尿碘中位数为143μg/L,5个乡镇孕妇的尿碘含量的分布不同,差异有统计学意义(H=15.68,P<0.05)。儿童甲状腺肿大率为1.00%。孕妇健康教育知晓率为69.00%。结论化州市碘缺乏病防治措施落实,防控效果较好;居民碘营养现状总体处于适宜水平,但孕妇碘营养水平偏低,乡镇之间存在地区差异,孕妇的防治知识知晓率偏低。今后需加强监测及健康教育力度,坚持因地制宜和科学补碘,持续消除碘缺乏危害。 Objective To analyze the monitoring results of iodine deficiency disorders in Huazhou and to understand the status of iodine deficiency and iodine deficiency among urban and rural residents in Huazhou and to provide a scientific basis for the development of targeted prevention and treatment measures for iodine deficiency disorders. Methods A township / street was randomly selected from five directions in Huazhou city at east, west, south, north and south. Four administrative villages were randomly selected from each township / street, and 15 households were selected randomly from each administrative village Salt samples were collected. One primary school was randomly selected in the townships sampled and 40 children aged 8-10 were selected randomly from primary schools to monitor the urinary iodine content and goiter of children. Twenty pregnant women were randomly selected in each township, Monitoring urinary iodine content of pregnant women and family consumption of salt samples, of which 10 pregnant women prevention and control knowledge survey. Results The household consumption of qualified iodized salt was 97.33%, the median of iodized salt was 24.29 mg / kg, and the median of iodized salt of pregnant women was 23.90 mg / kg. There was no significant difference in the eating rate of iodized salt between household and pregnant women Significance (χ ~ 2 = 0.46, P> 0.05). The median urinary iodine of children was 195.00μg / L, and the distribution of urinary iodine in five township school-age children was different, with a statistically significant difference (H = 10.44, P <0.05). The median urinary iodine of pregnant women was 143μg / L The distribution of urinary iodine in pregnant women in 5 townships was different, the difference was statistically significant (H = 15.68, P <0.05). Goiter in children was 1.00%. Pregnancy health education awareness rate was 69.00%. Conclusion The prevention and control measures for iodine deficiency disorders in Huazhou City are well implemented and the prevention and control effects are good. The current status of iodine nutrition in residents is generally at an appropriate level, but the iodine nutrition level of pregnant women is low, and there are regional differences among villages and towns and the prevention rate of pregnant women is low. In the future, monitoring and health education should be stepped up. Insisting on adapting to local conditions and science, it will continue to eliminate the harm of iodine deficiency.
