iodine deficiency

Risk Factors
Hey Epidemiologists Please add a bit more on risk factors, it would be fun knowing the mechanism of actions of the risk factors. didnt have references of few so if anyone could add that too, would be a great help. enjoy discover and share knowledge

The first sentence describes iodine, when it should describe iodine deficiency. —Preceding unsigned comment added by 134.155.89.247 (talk) 01:30, 30 May 2010 (UTC)

Is this really a scientifically approved test? To me it certainly doesn't sound like it is. I suggest it is removed.--Bjornwireen 22:09, 7 November 2007 (UTC)


 * You're right. I removed that external link. But please use this template on the article's page. Thank you for the notice! NCurse work 18:44, 8 November 2007 (UTC)

Netherlands?
Why is the Netherlands listed as one of the countries with iodine deficiency problems? I live there and I've never heard about it being a problem. Our salt is iodized so I can't see how we fit in that list. Xaphire (talk) 18:00, 31 January 2008 (UTC)


 * Because it has had a long history of iodine deficiency problems. The spotty history of iodinization of salt in the Netherlands is given here:
 * http://www.sph.emory.edu/PAMM/present/7-justus/tsld004.htm
 * Also, note that iodization of salt does not guarantee uniform and adequate iodine nutrition; far from it. It is a great start, but that's all.
 * Alan2012 (talk) 02:20, 27 August 2008 (UTC)


 * Agree. Iodized salt doesn't help much if you use no salt because of fear of too much salt will harm you.

I agree, I live there and salt has been iodised since the second world war or so, hence removed, also it would've been 'The Netherlands' Probably someone afflicted by cretinism. Also, no mountains, so how? 41.241.180.193 (talk) 22:04, 22 August 2008 (UTC)


 * Iodine deficiency does not occur only in mountains. It occurs all over.

UK, Germany
You can't buy iodized salt in the UK, while in Germany you find it on the shelves of every supermarket.

Australia
Australia has also been listed, and I have the same comment! —Preceding unsigned comment added by 203.94.54.14 (talk) 01:49, 22 April 2008 (UTC)


 * Yes, Australia, too. See below.

School of Public Health, University of Sydney, Edward Ford Building (A27), Sydney, NSW 2006, Australia. muli@health.usyd.edu.au

OBJECTIVE: To document the population iodine nutritional status in Australian schoolchildren. DESIGN AND SETTING: Cross-sectional survey of schoolchildren aged 8-10 years, based on a one-stage random cluster sample drawn from all Year 4 school classes in government and non-government schools in the five mainland Australian states of New South Wales, Victoria, South Australia, Western Australia and Queensland. The study was conducted between July 2003 and December 2004. PARTICIPANTS: 1709 students from 88 schools (881 boys and 828 girls), representing 85% of the estimated target number of students. The class participation rate was 65%. MAIN OUTCOME MEASURES: (i) Urinary iodine excretion (UIE) levels (compared with the criteria for the severity of iodine deficiency of the World Health Organization/International Council for the Control of Iodine Deficiency Disorders: iodine replete, UIE > or = 100 microg/L; mild iodine deficiency, UIE 50-99 microg/L; moderate iodine deficiency, UIE 20-49 microg/L; severe iodine deficiency, UIE < 20 microg/L); (ii) Thyroid volumes measured by ultrasound (compared with new international reference values). RESULTS: Overall, children in mainland Australia are borderline iodine deficient, with a national median UIE of 104 microg/L. On a state basis, NSW and Victorian children are mildly iodine deficient, with median UIE levels of 89 microg/L and 73.5 microg/L, respectively. South Australian children are borderline iodine deficient, with a median UIE of 101 microg/L. Both Queensland and Western Australian children are iodine sufficient, with median UIE levels of 136.5 microg/L and 142.5 microg/L, respectively. Thyroid volumes in Australian schoolchildren are marginally increased compared with international normative data obtained from children living in iodine sufficient countries. There was no significant association between UIE and thyroid volume. CONCLUSION: Our results confirm the existence of inadequate iodine intake in the Australian population, and we call for the urgent implementation of mandatory iodisation of all edible salt in Australia.

Almost half of all Australian primary school children are mild to moderately iodine deficient, putting their mental and physical development at risk, researchers say.

critinism??
"mistaken for the word 'critinism' originating in the French word 'cretin'". I can't see this early possible version in the OED. Should it still be "cretinism"? Myrvin (talk) 08:28, 4 March 2008 (UTC)


 * Yes. Cretinism.

Deficiency in USA
I don't know how to edit pages, but I think it would be worthwhile to document some of the known deficiency levels around the world. In particular, around 11.3% of Americans are moderately to severely deficient.

NIH study from 2003-2004

216.166.58.170 (talk) 20:57, 29 September 2009 (UTC)  This promo from a Dr Brownstein claims iodine deficiency is significant / unappreciated by north american doctors (& big pharma) and is responsible for many cancers and other health problems as noted herein. He also claims that salt manufacturers have substituted other similar elements for iodine to save costs, despite negative risks. His claims may well be bunkum but should be easy to refute if so. Can someone look into this, do some tests and let us know if there is something to his claims, even if they are a bit over the top (like everyone else, lol). Thanks.

An update of U.S. iodine status was published in 2011: Caldwell KL, Makhmudov A, Ely E, Jones RL, Wang RY. Iodine status of the U.S. population, National Health and Nutrition Examination Survey, 2005–2006 and 2007–2008. Thyroid. 2011 Apr;21(4):419-27. Caldwell and others use urinary iodine concentration as micrograms per liter because >90% of consumed iodine ends up being excreted in urine. Definitions for mild, moderate and severe iodine deficiency are set at 50-100 ug/L, 20-50 ug/L and <20 ug/L. Caldwell reported about 1% of U.S. population severe, 8-11% moderate and 20-32% mild. Some age groups more likely deficient than others.David notMD (talk) 14:02, 5 February 2017 (UTC)

NHANES data and Caldwell's report are based on urinary iodine concentration (UIC) rather than calculating iodine intake from foods. This 2016 reference compares food intake surveys versus UIC to consider whether assessment of iodine status can be improved: Juan W, Trumbo PR, Spungen JH, Dwyer JT, Carriquiry AL, Zimmerman TP, Swanson CA, Murphy SP. Comparison of 2 methods for estimating the prevalences of inadequate and excessive iodine intakes. Am J Clin Nutr. 2016 Sep;104 Suppl 3:888S-97S. David notMD (talk) 13:48, 5 February 2017 (UTC)

Pearce 2016 points out that UIC is a valid population assessment tool, but does not indicate how individuals are adapting (or not) to low iodine intake. Discusses thyroid hormones and perhaps thyroglobulin as biomarkers: Pearce EN, Caldwell KL. Urinary iodine, thyroid function, and thyroglobulin as biomarkers of iodine status. Am J Clin Nutr. 2016 Sep;104 Suppl 3:898S-901S. doi: 10.3945/ajcn.115.110395. Review. PubMed PMID: 27534636. David notMD (talk) 14:20, 5 February 2017 (UTC)

Goiter
I tried to clarify the T4-T3-TSH links in iodine deficiency. It is many T4 levels that regulate TSH release, as shown by Reed Larsen. Pustelnik (talk) 17:39, 16 August 2010 (UTC)

Orphaned references in Iodine deficiency
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Iodine deficiency's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "Patrick2008": From Iodine:  From Thyroid:  

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 20:15, 29 October 2010 (UTC)

Deficiency costing Germany 1 billion?
I looked into this statement, which seems a bit far fetched: "In Germany, it has been estimated to cause a billion dollars in health care costs per year."

The source for this statement is here: http://www.thorne.com/altmedrev/.fulltext/13/2/116.pdf

This paper has a further source listed as: Gutekunst R. Iodine deficiency costs Germany over one billion dollars per year. IDD Newsletter 1993;9:29-31.

Here is a link to the IDD Newsletter: http://iccidd.server295.com/media/IDD%20Newsletter/1991-2006/idd293.htm

'''I could not find any references to back up this statement. I propose the statement be removed from the page.""

 * It was not that hard, it might be actually even more than 1 billion: Richiez (talk) 22:42, 9 March 2011 (UTC)

need to update dead link in reference 1
Nice article. reference 1 link is dead link. reference 1 is supposed to link to- http://www.thyroidmanager.org/chapter/the-iodine-deficiency-disorders/ which is a great scientific article - with pictures of iodine deficiency in humans. I used to correct things like this all the time but I can't work out how to do it with the new "ref list" format...... sorry - you need to do it yourself !
