【摘要】：目的研究新標碘鹽供應前后廈門市沿海8-10歲兒童和孕婦的碘營養(yǎng)變化情況,為下一步碘缺乏病防控策略調(diào)整提供實證依據(jù)。方法在新標碘鹽供應前及食用新標碘鹽后的第3、6、9個月調(diào)查廈門市翔安區(qū)8-10歲學生和孕婦的尿碘、尿比重、碘鹽覆蓋率、碘鹽合格率、合格碘鹽食用率和居民日人均食鹽攝入量。結果自來水水碘含量為4.2μg/L,基線調(diào)查、第二、三次評估日人均食鹽攝入量均數(shù)分別為5.7、6.9、6.9 g;基線調(diào)查、第一、第二、三次評估,8-10歲學生碘鹽合格率和合格碘鹽食用率都分別為97.1、93.1、98.0和98.0,鹽碘中位數(shù)分別為28.7、24.7、24.0、25.3 mg/kg,尿碘中位數(shù)分別為132.0、177.7、181.7和134.5μg/L,尿比重均值分別為1.0157、1.0196、1.0213和1.0184;孕婦碘鹽合格率分別為97.8%、84.6%、84.4%和90.2%,鹽碘中位數(shù)分別為27.8、25.7、24.3和23.7mg/kg,尿碘中位數(shù)分別為103.8、128.5、138.9和100.2μg/L,尿比重均值分別為1.0123、1.0153、1.0180和1.0143;尿碘與采樣季節(jié)、氣候及尿比重有關,尿碘值與尿比重呈正相關關系。結論新標碘鹽實施前后,8-10歲兒童碘營養(yǎng)總體處于適宜水平,但孕婦碘營養(yǎng)均不足,要采取措施加強孕婦碘營養(yǎng),保障人群健康素質(zhì)。
[Abstract]:Objective to study the changes of iodine nutrition in children and pregnant women aged 8 years and 10 years old in Xiamen coastal area before and after the supply of new standard iodized salt, and to provide empirical basis for the adjustment of prevention and control strategies for iodine deficiency disorders (IDD) in the next step. Methods the urinary iodine, urine specific gravity, iodized salt coverage and qualified rate of iodized salt were investigated before and after the consumption of new standard iodized salt in Xiangan District of Xiamen City before and 3, 6 months after consumption of new standard iodized salt, and the urine iodine, urine specific gravity, iodized salt coverage rate and qualified rate of iodized salt were investigated in Xiangan District of Xiamen City. Qualified iodized salt consumption rate and daily per capita salt intake. Results the iodine content in tap water was 4.2 渭 g / L, and the average daily salt intake per capita was 5.7, 6.9 and 6.9 g, respectively. The first, second and third assessments showed that the qualified rate of iodized salt and the consumption rate of qualified iodized salt were 97.1, 93.1, 98.0 and 98.0, respectively, and the median of salt iodine was 28.7, 24.7, 24.0 and 25.3 mg/kg, respectively. The median of urinary iodine was 132.0177.7181.7 and 134.5 渭 g / L, and the mean urinary specific gravity was 1.0157, 1.0196, 1.0213 and 1.0184, respectively. The qualified rates of iodized salt in pregnant women were 97.8%, 84.6%, 84.4% and 90.2%, respectively. The median of salt iodine was 27.8, 25.7, 24.3 and 23.7 mg / kg, and the median of urinary iodine was 103.8128.5138.9 and 100.2 渭 g / L, respectively. The mean specific gravity of urine was 1.0123, 1.0153, 1.0180 and 1.0143, respectively. Urinary iodine was positively correlated with sampling season, climate and urine specific gravity, and urine iodine value was positively correlated with urine specific gravity. Conclusion before and after the implementation of the new standard iodized salt, the iodine nutrition of children aged 8 脳 10 years old is generally at a suitable level, but the iodine nutrition of pregnant women is insufficient. Measures should be taken to strengthen the iodine nutrition of pregnant women and ensure the health quality of the population.
