河北省低碘盐覆盖率地区重点人群碘营养状况调查

Objective To investigate the iodine nutrition status of the target population living in the areas with low coverage rate of iodized salt and to provide a basis to prevent and control iodine deficiency. Methods The investigation was carried out in the areas with coverage rate of iodized salt lower than 80%, including 7 counties (city, district). Three townships(sub-district office) were sampled in each county and two elementary schools in each township(sub-district office). Urinary iodine level was measured for 40 children aged from 8 to 10 years old in each elementary school. Drinking water iodine was collected and determined in their living villages. Twenty salt samples were tested for iodine in salt from 20 house which had fertile women, and urine iodine of 10 fertile women were tested in each village. Results Sixty-two water samples were determined and the water iodine was ranged from 5.8 to 272.7 μg/L, of which 3 water samples were equal and more than 150 μg/L. Eight hundred and seventy-two salt samples were collected. The coverage rate of iodized salt was 70.74%(585/827) and the coverage rates were below than 80% in 5 counties (city, district). A total of 1660 children' urine samples were collected, the content of urine iodine ranged from 10.0 to 1088.0 μg/L and the urine iodine median was 173.7 μg/L. Four hundred and thirty-seven urine samples were collected from the fertile women and the urine iodine median was 179.1 μg/L. The iodine level of children and women was the highest in Dongguang County(251.8,273.8 μg/L) while that of Hejian County (130.8,118.7 μg/L) was the lowest. Conclusions Although the iodine nutrition of children and fertile women is appropriate in areas with low coverage rate of iodized salt, we presume from the results that the possibility of iodine deficiency in pregnant and lactating women exists in Hejian and Anping.

Abstract：

Objective To investigate new cases of endemic cretinism in high-risk areas of Inner Mongolia, the prevalence of endemic goiter, the implementation of comprehensive measures, and to provide scientific basis for developing control strategies against iodine deficiency disorders (IDD). Methods In 2007 and 2008, a search for new cretin cases was conducted among children under the age of 10 in 11 historical serious epidemic cretinism prevalent areas of Songshan district, Keshiketeng qi, Kalaqin qi, Zhalaite qi, Zhuozi county,Liangcheng county, Qingshuihe county, Helin county, Dongsheng district, Zhungeer qi and Yinjinhuoluo qi. Three to 5 towns were selected in each qi(county, district) and 3 to 5 village primary schools were selected in each town.One hundred and twenty to 200 children aged 8 to 10 were selected in each school to inspect thyroid by B ultrasound and palpation and to test intelligence and urinary iodine. Two villages were selected in each town and 30 households were selected to determine urinary iodine of housewives and salt iodine. Results A total of 56 cases of suspected cases of endemic cretinism were found from the 11 counties but no case was confirmed. The goiter rate of children aged 8 to 10 was 5.2% (309/5922) by palpation and 4.3% (252/5922) by B-ultrasound. The median urinary iodine of children aged 8 to 10 was 241.5 μg/L, and urinary iodine was 100 to 300 μg/L, accounted 65.9%(3901/5920). Median urinary iodine of the 9 Qis(counties, districts) was in the range of 200 and 300μg/L.Higher than 5% of the 11 Qis(counties, districts) with urinary iodine lower than 50 μg/L was zero. Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 1. The median urinary iodine of housewives was 225.6 μg/L, and lower than 50 μg/L accounted for 2.2%(35/1597). Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 4. A total of 2109 households were investigated and 97.45%(2055/2109) of them ate iodized salt and 2.55%(54/2109) of them ate non-iodized salt. Conclusions In the 11 investigated counties, goiter rate of children has decreased to less than 10%, and no new cretin was found. It could be concluded that the fulfillment of prevention and control of IDD is effective. The iodine nutrition of children and women of childbearing age is in an adequate level. The coverage rate of iodized salt has maintained at a higher level, the sales network is sound, the salt price is reasonable and salt is easy to get and the children's intelligence is protected effectively. But, the health education about IDD is still weak, need to be reinforced.
