Objective To clarify the effect of iodine intake on serum thyroglobulin (Tg). Methods A 5-year prospective study was conducted in the 3 different iodine intake areas in China [Panshan (miht deficiency) ,Zhangwu (more than adequate) and Huanghua (excess)]. A total of 3 099 people with normal serum levels of Tg in 1999 were followed and 2 448 of these participants were feasible to be observed in 2004 and included in the present study. The serum levels of Tg, thyraglobulin antibody(TgAb), thyroid peroxidase antibody(TPOAb) and TSH, thyroid volume, family and personal histories of thyroid diseases were measured and inquried. The general linear model (GLM) was used to explore the determinants of Tg. Results Among the study population at baseline, serum Tg were significantly different in three areas [7.5 (4.4-13. 1) μg/L at Panshan, 6.8 (3.6-11.2)μg/L at Huanghua, 5.9 (3.2-10.7) μg/L at Zhangwu, P<0.01]. They were associated with age, sex and the rate of positive TgAb, abnormal thyroid volume, abnormal TSH and positive personal history of thyroid diseases, in order to control the effects of confounding factors, the data from 1856 subjects with thyroid-related indexes all in normal range and without personal history of thyroid diseases were analyzed to clarify the effect of iodine intake on Tg. The serum Tg among three areas were significantly different in both 1999 and 2004, they were all increased in 5 years with significant augment (△ Tg) among the three areas[3.1 (-0.2-8.0) μg/L at Panshan, 3.5 (0.5-9.0)μg/L at Huanghua vs 2. 5(0.3-6.1) μg/L at Zhangwu,P<0.01]. The GLM analysis revealed that age, Tg and TSH levels at baseline were the determinants of △Tg in addition to iodine intake. Conclusion Iodine intake is a dominant determinant of serum Tg. Age and TSH should also be considered while indicating iodine intake by serum Tg. 相似文献

Objective To study the effects of different level of iodine nutrition on the thyroid function in women of reproductive age. Methods A total of 100 (50 from each) women of reproductive age but not pregnant were collected from iodine deficient and adequate areas. The questionnaire was obtained individually with items concerning personal history of thyroid diseases, goiters and category of edible salt and drinking water based on the project design. The household salt and drinking water were collected for measuring iodine content, and blood samples were obtained for TSH, FT4 and FT3 testing. Results The coverage of iodized salt and the median level of urinary iodine in iodine deficient women(72.0% and 95.5 μg/L) were obviously lower than that in iodine sufficient women(100.0% and 167.4 μg/L, χ2=16.28, U = 632.00, P < 0.01). Median level of serum TSH in iodine deficient women (2.56 m U/L) appeared in an increasing tendency compared to the iodine sufficient women (1.88 mU/L), but there was no significance (U=990.50, P > 0.05). Serum FT4 mean level in iodine deficient women [(14.7±2.0) pmol/L]was lower than that in iodine sufficient women[(17.0±3.8)pmoI/L, t=3.76, P<0.01]. There was no difference in serum FT3 between two group women[(5.1±1.4), (4.8±0.5)pmoI/L, t = 1.59, P > 0.05]; but FT3/FT4 ratio in iodine deficient women(0.33±0.04) was markedly higher than that in the iodine sufficient women(0.30±0.04, t=3.13, P<0.01). The percentage of thyroid dysfunction in iodine deficient women[20.0% (10/50)]was higher compared with the iodine sufficient women[8.0%(4/50)], but without significance(χ2=2.99, P>0.05). Conclusions Iodine deficiency is a primary cause leading to hypothyroid in women of reproductive age. Long term of iodized salt usage is an efficient way to correct iodine deficiency. 相似文献

Results The coverage of iodized salt and the median level of urinary iodine in iodine deficient women(72.0% and 95.5 μg/L) were obviously lower than that in iodine sufficient women(100.0% and 167.4 μg/L, χ2=16.28, U = 632.00, P < 0.01). Median level of serum TSH in iodine deficient women (2.56 m U/L) appeared in an increasing tendency compared to the iodine sufficient women (1.88 mU/L), but there was no significance (U=990.50, P > 0.05). Serum FT4 mean level in iodine deficient women [(14.7±2.0) pmol/L]was lower than that in iodine sufficient women[(17.0±3.8)pmoI/L, t=3.76, P<0.01]. There was no difference in serum FT3 between two group women[(5.1±1.4), (4.8±0.5)pmoI/L, t = 1.59, P > 0.05]; but FT3/FT4 ratio in iodine deficient women(0.33±0.04) was markedly higher than that in the iodine sufficient women(0.30±0.04, t=3.13, P<0.01). The percentage of thyroid dysfunction in iodine deficient women[20.0% (10/50)]was higher compared with the iodine sufficient women[8.0%(4/50)], but without significance(χ2=2.99, P>0.05). Conclusions Iodine deficiency is a primary cause leading to hypothyroid in women of reproductive age. Long term of iodized salt usage is an efficient way to correct iodine deficiency. 相似文献

Objective To study the effects of different level of iodine nutrition on the thyroid function in women of reproductive age. Methods A total of 100 (50 from each) women of reproductive age but not pregnant were collected from iodine deficient and adequate areas. The questionnaire was obtained individually with items concerning personal history of thyroid diseases, goiters and category of edible salt and drinking water based on the project design. The household salt and drinking water were collected for measuring iodine content, and blood samples were obtained for TSH, FT4 and FT3 testing.

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. 相似文献
