目的:了解杭州市上城区重点人群的碘营养状况,为碘缺乏病防治工作提供科学依据。方法:采取多阶段分层随机抽样法每年分别抽取8岁~10岁学生约200名、孕妇或哺乳期妇女约50名,进行碘营养水平监测。结果:8岁~10岁学生家庭食用盐的碘中位数(P25~P75)为26.1(21.7~30.8)mg/kg,尿碘中位数(P25~P75)为181.2(123.1~256.5)μg/L;孕妇或哺乳期妇女食用盐碘中位数(P25~P75)26.2(21.9~30.4)mg/kg,尿碘中位数(P25~P75)104.5(70.6~164.5)μg/L。结论:杭州市上城区重点人群处于碘营养适宜状况,但是孕妇及哺乳期妇女碘营养水平比学生人群低,存在碘缺乏的危险,应根据不同状况给予营养指导。

Methods: A multi-stage stratified random sampling method was used to draw out about 200 students from 8 years old to 10 years old and about 50 pregnant women or lactating women respectively to monitor the iodine nutrition level. Results: The median iodine (P25 ~ P75) of household edible salt was between 8 years old and 10 years old was 26.1 (21.7-30.8) mg / kg and the median of urinary iodine was 181.2 (123.1 ~ 256.5) μg / L; median of salt iodine (P25 ~ P75) 26.2 (21.9 ~ 30.4) mg / kg, median urinary iodine (P25 ~ P75) 104.5 (70.6 ~ 164.5) μg / L of pregnant women or lactating women. Conclusion: The key population in Shangcheng District of Hangzhou is in the suitable status of iodine nutrition.
