天津市实施全民食盐加碘措施后各种人群碘营养现状的调查研究

IODINE NUTRITIONAL INVESTIGATION OF POPULATIONS INTIANJIN CITY SINCE UNIVERSAL SALT IODIZATION AS A MAJOR IMPLEMENT

了解天津市在实施全民食盐加碘措施后各种人群在仅食用合格碘盐条件下的碘营养状况。方法：选取天津市区成人、孕妇、乳母和婴儿为观察对象，以尿碘、乳碘中位数为主要观测指标。结果：除哺乳期妇女外，其他各种人群的碘缺乏均得到纠正。哺乳期妇女尿碘中位数低于１００μｇ／Ｌ（为９１．５μｇ／Ｌ），其原因可能是乳腺代偿性加强了浓集碘的功能而使其自身处于轻度缺碘状态。结论：哺乳期妇女需补服富碘食物。

Objective: To evaluate the iodine nutritional status since universal salt iodization as major intervention has been implementedHZ Methods: To select various populations (adultpregnant womenlactating women and infants) in Tianjin city Their urinary iodine and iodine concentrations in breast milk as a major indication were determined Results: Except for lactating women,Iodine deficiency of all populations had been fully correctedThe uninary iodine level reached and was above 100g/L The uninary iodine level of lactating women was 915g/L Conclusion: The result suggested that the lactating women should increase iodine intake
