目的了解江苏省加碘食盐干预项目地区[5个县(区)]妊娠和哺乳期妇女碘营养状况。方法对近半月内未服用富碘药物的妊娠和哺乳期妇女同时测定尿碘、食盐碘含量;以尿碘值×成人每天平均排尿量作为推算的碘摄入量,以WHO推荐的碘摄入量作为评估标准。结果调查妊娠和哺乳期妇女1243人,推算的碘摄入量中位数为285.0μg/d,与WHO推荐的碘摄入量200μg/d比较,高出42.5%,但仍有382人的推算碘摄入量中位数<200μg/d,比例高达30%;妊娠和哺乳期妇女环境碘摄入量平均78μg/d,加碘食盐供给的碘摄入量达到210μg/d。非碘盐率为11.4%~12.0%。结论江苏省加碘食盐干预项目地区(县、区)妊娠和哺乳期妇女碘摄入量水平基本上达到消除碘缺乏病(IDD)标准,但非碘盐比例有回升趋势,存在潜在危险。
Objective To understand the iodine nutrition status of pregnant and lactating women in five counties (districts) of iodized salt intervention project in Jiangsu Province. Methods Pregnant and lactating women who did not take iodine-rich drugs within the past half month were tested for urinary iodine and salt iodine. Urinary iodine value × average daily urine output of adults was used as the estimated iodine intake. The iodine intake recommended by the WHO Quantity as the evaluation criteria. Results A total of 1,243 pregnant and lactating women were surveyed. The median estimated iodine intake was 285.0 μg / d, which was 42.5% higher than the WHO recommended iodine intake of 200 μg / day. However, there were still 382 projections The median iodine intake was less than 200μg / d, with a high proportion of 30%. The iodine intake of pregnant women and lactating women averaged 78μg / d and the iodine intake of iodized salt reached 210μg / d. Non-iodized salt rate of 11.4% ~ 12.0%. Conclusion Iodine intake in pregnant and lactating women in iodized salt intervention areas in Jiangsu Province basically reached the standard of eliminating iodine deficiency disease (IDD), but the non-iodized salt proportion had a tendency of upward trend with potential risks.
