目的了解甘肃省张掖市居民碘营养状况,为调整防治策略提供科学依据。方法在选中的项目县按东、西、南、北、中5个方位随机抽取5个乡;每个乡随机抽取1所小学8~10岁儿童尿样20份;每个乡随机抽取孕妇、哺乳期妇女尿样各5份测定尿碘。结果共检测8~10岁儿童尿样399份,尿碘中位数为239.91μg/L,<100μg/L的占4.26%,>200μg/L占65.91%;检测孕妇和哺乳期妇女尿样198份,尿碘中位数246.58μg/L,<150μg/L占14.65%,>300μg/L占37.88%。结论甘肃省张掖市居民碘营养充足,重点人群尿碘过量比例较高,希望通过适当调整盐碘浓度,提高居民碘营养适宜水平。
Objective To understand the iodine nutrition status of residents in Zhangye City, Gansu Province and to provide scientific basis for adjusting prevention and control strategies. Methods Five townships were randomly selected from five locations in the selected project counties of East, West, South, North and North. A sample of 20 urine samples from 8 to 10-year-old children in each township was randomly selected. Pregnant women, Urine samples of lactating women were measured in 5 urine iodine. Results A total of 399 urine samples were collected from 8 to 10 years old children with urinary iodine median of 239.91μg / L, accounting for 4.26% for those with 100μg / L and 65.91% for patients receiving 200μg / L urine. The urinary iodine median of 246.58μg / L, <150μg / L accounted for 14.65%,> 300μg / L accounted for 37.88%. Conclusion Residents in Zhangye City, Gansu Province, have adequate iodine nutrition and a high proportion of urinary iodine excess in key populations. It is hoped that iodine nutrition can be adjusted appropriately to improve the appropriate level of iodine nutrition for residents.
