摘要
目的掌握河北省滦州市碘缺乏病重点人群碘营养状态,科学评估防治效果,为优化防治方案、精确补碘提供依据。方法于2020-09,滦州市以镇(街道)为单位,按东、南、西、北、中5个方位各随机抽取1个镇(街道)设为监测点;每个监测点抽取同校810岁走读学生确定为目标人群,进行尿碘含量检测,同时采集其家庭正常食用的食盐进行盐碘含量检测,对所得学生尿碘及盐碘数据,采用x(x±s)、中位数M(P_(25)-P_(75))描述;假设检验采用Mann-Whitney U、Kruskal-Wallis检验,以P<0.05为差异有统计学意义。结果共采集检测学生尿液样品200份,家用食盐样品200份;尿碘中位数262.98μg/L,超过尿碘适宜量;盐碘含量均值22.31 mg/kg,处在标准允许波动范围内;不同性别、不同年龄学生尿碘含量无显著性差异;镇(街道)样品尿碘中位数最高为360.68μg/L,最低为195.82μg/L,不同镇(街道)样品尿碘结果差异有统计学意义(χ^(2)=21.09,P<0.01)。结论滦州市重点人群尿碘含量、居民合格碘盐食用率符合国家相关标准,碘缺乏病防治效果成效明显;古城街道、茨榆坨镇两个镇/街存在高碘风险,应加强碘营养状态监测,防止高碘性疾病发生;同时应加强本地饮水碘含量监测,为因地制宜、科学优化人群补碘方案提供数据支持。
Objective To understand the iodine nutritional status of the key population at risk of iodine deficiency disorders in Luanzhou city of Hebei Province,and to scientifically evaluate the control effect,so as to provide basis for optimizing the control plan and accurately supplying iodine.Methods In September 2020,one town (district) was randomly selected from each of five directions of east,south,west,north and middle in Luan Zhou City.Then,8-10-year-old students from a school were chosen to test the urine iodine.Meanwhile,the household salt of the selectedstudents was collected to test the salt iodine content.The content of urinary iodine and salt iodine was expressed by mean±standard deviation and median (P_(25)-P_(75)).Mann Whitney U andKruskal Wallis test were performed,and P<0.05 was considered as statistically significant.Results Totally,200 urine samples from students and 200 household salt samples were collected for testing.The median of urine iodine was 262.98μg/L,which is over the upper limit of adequate range of urine iodine.The average iodine content in salt was 22.31 mg/kg,which is within the standard allowable fluctuation range.There was no significant difference in urinary iodine content among students of different genders and ages.The highest and lowest median of urinary iodine of samples from towns (districts) was 360.68μg/L and 195.82μg/L,respectively.The median of urinary iodine in different towns (streets) was statistically different(χ^(2)=21.09,P<0.01) Conclusion The urinary iodine content of key population and the consumption rate of qualified iodized salt met the relevant national standards in Luanzhou City.There is a risk of iodine excess in Gucheng street and Ciyutuo town,and monitoring of iodine nutrition status should be strengthened to prevent the occurrence of iodine excess diseases.Meanwhile,monitoring of iodine content in local drinking water should be strengthened to provide data support for scientifically iodine supplement programs based on local conditions.
