It is healthy that the ultra sufficient iodine nutrition state threatens the thyroid gland

It is healthy that the ultra sufficient iodine nutrition state threatens the thyroid gland
It is reported (Reporter Korea S. Lu) Chinese Medical Association endocrine credit can announce the China first urbanite's thyroid gland disease epidemiology investigation result a few days ago. Investigation show, in 15181 resident that is poll, have 1 the intersection of hypothyroidism and disease (including clinical first make a reduction of with inferior clinical first making a reduction of promptly in the every 15 people, abbreviate as first, make a reduction of in unison as follows) Patient, there are nearly a persons that have thyroid gland tubercle in every 5 people.
This investigation basically reflects the iodine nutritional status of eastern city in our country
It is introduced, this project is started in March of 2009, to Beijing with whole group of sampling methods, Chengdu, Guangzhou, Guiyang, the resident residents of the community investigate the disease epidemiology system of thyroid gland over 15181 20 of Jinan, Nanjing, Shanghai, Shenyang, Wuhan, Xi'an 10 cities. The investigation including questionnaire, scene physical detection, thyroid gland Ultrasonography B checks, adopt the empty stomach vein not to resist blood coagulation, empty stomach urine sample sample. Compared with the situation that iodine of Liaoning Province in 2006 causes the flowing and adjusting of project of the second of of the thyroid gland, this time in the the residents polled, first makes a reduction of the ill rate to already improve from 3.8% to 6.5%, thyroid gland tubercle( Including single shot and pilosity tubercle) Been ill for rate improve to 18.6% from 10.2%.
Will wait and take the post as General Board, thyroid gland and study introduction of Teng WeiPing, group leader of group according to Chinese Medical Association's endocrine credit, in 10 cities that choose of this investigation, 4 cities are in the ultra sufficient state (the iodine median of urine lie between 200 micrograms 300 micrograms liter) of iodine ,6 cities are in the sufficient state of iodine (the iodine median of urine lie between between 100 micrograms and 200 micrograms liter, it is that the iodine is suitable for the state) ,Have iodine lack district ' The iodine median of the urine is lower than 100 micrograms liter) With the excessive area of iodine ' The iodine median of the urine is higher than 300 micrograms liter) ,This investigation can basically represent iodine nutritional status of the eastern city in our country.
The educational circles of the endocrine agree in reduce the upper limit of content of iodized salting
Teng WeiPing says, this investigation has obtained disease ill rate and relation with iodine nutrition state of urban crowd's thyroid gland of our country for the first time. The result indicate, the clinic first of the intersection of iodine and ultra sufficient district make a reduction of, inferior clinical first make a reduction of and the ill rate of one's own antibody of thyroid gland is higher than the sufficient area of iodine by 2~3 times notably, verify again, it is unsafe that the iodine median of the urine exceeds 200 micrograms liter in terms of epidemiology. So, as to Ministry of Public Health in the recent food security national standard announced>China, the upper limit of iodine content of adding the salt is reduce to the revision of 30 milligrams kilogram from 60 milligrams kilogrammed, the educational circles of the endocrine show that totally agree. Teng WeiPing says, urbanite's iodine nutritional status and ill monitoring that led of of thyroid gland have offered the base-line data after this investigation was adjusted for the iodized salt standard too.
