我国四地区正常孕妇的尿碘水平分析

目的 以世界卫生组织(WHO)推荐的标准作依据,分析我国正常孕妇的尿碘水平,推荐作为评价孕妇人群碘营养状况的参考值,用于孕期碘营养监测及其相关研究.方法 在横断面调查中选择健康、碘营养充足、甲状腺功能正常、甲状腺自身抗体阴性的604名孕妇和192名当地非妊娠妇女作为本次研究对象,采用标准方法检测饮水、食盐、尿液的碘含量,采用化学发光免疫测定方法检测血清TSH、FT4、FT3、甲状腺过氧化物酶抗体(TPOAb)、甲状腺球蛋白抗体(TgAb).结果 (1)平均饮水碘含量为3.0μg/L,提示饮水提供的碘量很低.(2)平均食盐碘含量为31.7mg/kg,推测每日至少从食盐中获得240μg碘(按每人每日摄盐10 g计算,再减去烹饪过程可能丢失20%碘量),足以满足孕妇对碘的需求量.(3)604名孕妇的尿碘中位数为173.1μg/L,早、中、晚孕期分别为174.5、167.0和180.7μg/L,均达到了WHO推荐的150～249μg/L适宜水平,但未超过200μg/L.非妊娠妇女尿碘中位数为240.2μg/L,达到了WHO推荐的成人200-299 μg/L"超需要量"水平.(4)这些妇女都是甲状腺功能正常及抗体阴性者,但孕期TSH水平明显低于非妊娠妇女,以孕早期为最低;FT4及FT3,也低于非妊娠妇女,并随孕期进展而逐渐降低.结论 WHO推荐的孕妇适宜尿碘中位数水平(150-249μg/L)适用于我国孕期妇女,但我国孕妇尿碘偏低,位于150-200μg/L之间;同地区的非妊娠妇女尿碘水平偏高,建议市场可以供应不同浓度碘盐以满足不同人群的需求.

Abstract：

Objective To analyze the median urinary iodine(MUI)level in normal pregnant women based on World HeMth Organization(WHO) recommended criterion,and to provide the MUI reference values for monitoring and evaluating iodine nutrition during pregnancy and related studies.Methods Total 604 normal pregnant and 192 non-pregnant women(as a comparison)were selected from a cross-sectional survey.These women were all healthy,iodine sufficient,with normal thyroid function,and negative anti-thyroid antibodies.The iodine content in drinking water,edible salt,and urine was determined by standard methods,and serum TSH,FT4,FT3,thyroid peroxidaseantibody(TPOAb),and thyroglobulin antibody(TgAb)were measured using chemiluminescent immunoassay.Resuits (1)The iodine in drinking water was 3.0μg/L indicating such small amount of iodine could be neglected for daily iodine intake.(2)All women consumed iodized salt with the median iodine in salt of 31.7 mg/kg.The daily iodine intake of at least 240 μg could be roughly estimated if an average of 10 g salt was taken per person per day and further subtracted by 20%iodine lost during cooking,which could meet the iodine needs during pregnancy.(3)The MUI of 173.1μg/L was calculated from 604 pregnant women having 174.5,167.0,and 180.7 μg/L during the first,second,and third trimesters,respectively,reaching the optimal level of 150-249 μg/L recommended by WHO for pregnant women.However,our data showed relatively lower levels,not reaching 200μg/L.The MUI of 240.2μg/L was calculated from 192 non-pregnant women,reaching the level of"above requirement"(200-299μg/L) recommended by WHO for adults.(4)All women were euthyroid and antibody-negative,but the TSH level in pregnant women was lower than that in non-pregnant women,in particular during the first trimester,while FT4 and FT3 were considerably decreased compared with the non-pregnant(with an exception of FT4 in the first trimester),and both gradually declined with the gestational age.Conclusions The optimal MUI level of 150-249 μg/,L recommended by WHO can be applied to pregnant Chinese women,but our data provided a relatively low range of 150-200μ/L throughout pregnancy.The higher MUI of 240.2μg/L in non-pregnant women indicated that iodized salt with different contents should be supplied on market to meet the requirement of different groups of population.

新疆阿克苏地区重点人群碘营养和智力水平调查

Objective To investigate the iodine nutritional status of school children, lactating women and infants in iodine deficient areas of Baicheng and Wushi Counties in Xinjiang Autonomous Region. Methods According to the geographic location of east, south, west and north of county, 10 primary schools of 8 townships were selected. In each school, 10 children among each gender and age group from 8 to 10 years old were selected. A total of 300 school children were chosen. One hundred and four infants aged 0-2 years old and their mother were selected in 8 townships. Iodine content in edible salt at household level, the urinary iodine in school children and lactating women, total goiter rate(TGR) and the status of the intelligence quotient (1Q) of school children, the status of psychological development of infants were observed. Direct titration assay for testing the salt iodine, colorimetric ceric-arsenic assay and vitriolic ammonium assimilation were used for testing urinary iodine. The size of thyroid gland was measured by palpation. The Combined Raven Test for Chinese Rural was used to test the IQ. The psychological development of infants was tested by Danver Development Screening Test (DDST). Results The coverage rate of iodized salt at household level was 73.1% (123/182), however, the proportion of households using adequately iodized salt was 64.1% (118/182). The medium of urinary iodine in school children was 103.7 μ/L, with 47.8%(75/157) less than 100 μg/L and 28.0% (44/157) less than 50 μg/L; it was 123.0 μg/L in Baieheng County, with 44.4%(28/63) less than 100 μg/L and 33.3%(21/63) less than 50 μg/L; it was 100.3 μg/L in Wushi County, 50.0%(47/94) less than 100 μg/L and 24.5%(23/94) less than 50 μg/L. The medium of urinary iodine in locating women was 143.3 μg/L, it was 119.7 μg/L and 184.6 μg/L in Baicheng and Wushi Counties, respectively. The total rate of goiter in school children was 14.3%(43/300), it was 10.8%(13/120) and 16.6%(30/180) in Baicheng and Wushi Counties, respectively. The average IQ in school children was 80.6±11.6, it was 83.0±11.6 and 79.0±11.7 in Baicheng and Wushi Counties, respectively. The proportion of mental retardation in school children (IQ≤69) was 13.0% (39/300), it was 6.7% (8/120) and 17.2%(31/180) in Baicheng and Wushi Counties, respectively. In addition, the proportion of psychological development in infants being normal, suspicious and abnormal was 78.8%(82/104), 12.5% (13/104) and 8.7%(9/104), respectively. Conclusion This study confirms the fact that there is also existence of mental retardation in children and infants, caused by iodine deficiency.
