Talk:Effect of health on intelligence

Mercury in fish and confusion

Another study found that pregnant women who consumed 340 grams of low-mercury containing fish with fatty acids per week have benefits that outweigh the risks for mercury poisoning.

Can't they just use substitutes for example omega 3-rich Linseed oil(flax oil)? Then Omega 3 is provided with no mercury exposure.I think this should be noted. — Preceding unsigned comment added by 83.10.81.69 (talk) 23:42, 10 March 2016 (UTC)

WOW!

This is a great well written, sourced article. It ought to be linked to more pages. I'm going to work on doing that now. futurebird 19:44, 22 January 2007 (UTC)

I concur.

This article requires authentication or verification by an expert.

This tag should be removed. The article has many solid sources. futurebird 20:26, 22 January 2007 (UTC)

In response to Futurebird's request on my talk page: To me, the article is, at a first glance, a collection of statements drawn from a variety of sources. It could be argued, that this provides a certain amount of credibility. However, I really prefer to have the article reviewed by a medical expert, since I (and probably no other reader) can easily verify and validate the sources. Let me remind you that scientific articles are also subjected to peer scrutiny. Kai A. Simon 20:55, 22 January 2007 (UTC)

Okay. How do we find an 'expert' ? (I was also wondering if you had any objections to these findings... recomendadtions for things that need to be better sourced, etc.)futurebird 21:09, 22 January 2007 (UTC)

Where to find an expert? Good question! I know a whole bunch of MDs, but I don't know, whether they are prepared to review the article. However, I can ask. I do not object the findins as such, since I cannot really assess them. Several of the statements appear to be totally reasonable. But, as I stated, I prefer a sound scientific review. Maybe this is a professional disease coming from working in a pharmaceutical company. :-)

I have expert knowledge regarding biomedicne. Furthermore, there is no Wikipedia policy requiring that a tag should remain indefinitely until a self-proclaimed expert may or may not look at it. If there are some concrete problems, please state them here.Ultramarine 23:15, 22 January 2007 (UTC)

breastfeeding

is it spelled breast feeding, breastfeeding, or breast-feeding? the article is breastfeeding. --WD RIK NEW 01:25, 31 January 2007 (UTC)

slight clarification

What does "Dutch conscripts" mean? In context, I thought at first it must mean Dutch civilians conscripted by the Nazis during the famine. "Draftees" or some other wording is needed to indicate that these intelligence measures pertain to those who were infants or prenatal individuals during the year 1944 but measured when they were conscripted for military service--unless I've guessed wrong about the actual intended meaning.

A Syntactic/Grammatical Error

"The article notes that children are more vulnerable and argues that new, precautionary approaches that recognise the unique vulnerability of the developing brain are needed for testing and control of chemicals in order to avoid the previous substantial * before starting restrictions on usage."

I believe that there should at least be a couple of words at * (such as the words 'cognitive losses'). I am uncertain that this alteration would make the sentence read better (ie: in context, the sentence *would* make sense, in a sense, though it could still do with more work!

ConcernedScientist 18:47, 27 June 2007 (UTC)

Some rewording is recommended in the "Toxins/Alcohol and drugs" subsection, namely the following sentence:

But another study instead looking at the relationship between environmental tobacco smoke exposure, measured with a blood biomarker, and cognitive abilities among U.S. children and adolescents 6–16 years of age, found an inverse association between exposure and cognitive deficits among children even at extremely low levels of exposure.

suggests inverse association between tobacco smoke exposure and cognitive deficits, but the source paper yields instead:

[...] there was a significant inverse relationship between serum cotinine and scores on reading [...], math [...], and block design [...] but not digit span [...].

which strongly suggests inverse association between tobacco smoke exposure and cognitive ability.

In the current state the casual reader could be easily misled, in my opinion.

Comments On the Stress Section

The following modifications might be well-placed in order to preserve article objectivity : “A group of largely African American urban first-grade children and their caregivers were evaluated using self-report, interview, and standardized tests, including IQ tests.”, should be converted to : As a example, a group of largely African American urban first-grade children and their caregivers were evaluated using self-report, interview, and standardized tests, including IQ tests.”

There are other possible improvements that could be made within this section. Making a point of the physiological action of the stress-hormone cortisone (I believe that this is the correct term) would provide a scientific basis/rationale for how IQ and intelligence (which are often given as having some sort of underlying physiological basis) can affect intelligence scores and the like. Of course, the brain in a complex entity, so making a point concerning how there may be a complex interaction between the physiological mechanisms of stress and other emotional stimuli would be valid.

I might add that I predict that others will criticise this section for making two specific mentions of one particular ethnic group over another. This might be interpreted as contravening article objectivity (even though they are only examples). Perhaps it would be best to focus on mixed group studies, as it done in relation to reference 59 (which occurs `at' the phrase “and lower IQ in children of all races.”).

Possible split

"Health" is an overly broad and vague concept. Perhaps this article should be split into "Nutritional Correlates of Intelligence", "Drug Use Correlates of Intelligence", "Disease Correlates of Intelligence" and "Lifestyle Correlates of Intelligence". Each of those articles could be quite large, assuming Naturalism. Jwray (talk) 12:02, 28 January 2008 (UTC)

Intelligence Citations Bibliography for Articles Related to IQ Testing

You may find it helpful while reading or editing articles to look at a bibliography of Intelligence Citations, posted for the use of all Wikipedians who have occasion to edit articles on human intelligence and related issues. I happen to have circulating access to a huge academic research library at a university with an active research program in these issues (and to another library that is one of the ten largest public library systems in the United States) and have been researching these issues since 1989. You are welcome to use these citations for your own research. You can help other Wikipedians by suggesting new sources through comments on that page. It will be extremely helpful for articles on human intelligence to edit them according to the Wikipedia standards for reliable sources for medicine-related articles, as it is important to get these issues as well verified as possible. -- WeijiBaikeBianji (talk) 16:23, 4 July 2010 (UTC)

By the way, what do you think about merging this article with some of the other articles about IQ on Wikipedia? -- WeijiBaikeBianji (talk) 02:25, 25 August 2010 (UTC)

Same question as before. Who is watching this article, and how does it fit with other articles on related topics? -- WeijiBaikeBianji (talk) 00:51, 21 October 2010 (UTC)

See no article it could be merged with or why it should be done.Miradre (talk) 04:55, 21 October 2010 (UTC)

Moving article to new name

See discussion here: [1].

So in order to differentiate it from "Cognitive epidemiology" this article needs a new name. One suggestion is "Impact of health on intelligence.".Miradre (talk) 22:11, 8 July 2011 (UTC)

An alternative is "Health factors affecting intelligence".Miradre (talk) 22:12, 8 July 2011 (UTC)

Well, "Impact of health on intelligence" was my proposal, and I stand by that. The other proposal is not good, because, quoting from WP:NAME: "Use nouns: Nouns and noun phrases are normally preferred over titles using other parts of speech. -- Adjective and verb forms (e.g. democratic, integrate) should redirect to articles titled with the corresponding noun (Democracy, Integration)"--Victor Chmara (talk) 22:37, 8 July 2011 (UTC)

Fine with me. I do not see this as a controversial move but will add a template and wait some time for more possible views.Miradre (talk) 23:13, 8 July 2011 (UTC)

Moved.Miradre (talk) 01:42, 11 July 2011 (UTC)

Hi, I missed this entirely.

I'm not sure the rationale of this name page can be that a page exists on Cognitive Epidemiology. CE studies often consider both directions, and reciprocity. They are also much broader than just IQ, and often consider biology->Health + biology->IQ (with no causal links from health to iq) and other models.

Seems much more helpful to have the link to CE, but keep this page on the specific sub-topic of how and why health and IQ might be linked. Alternatively have a page for H->IQ, another for IQ->H, and another for IQ<->H... seems unnecessary given how little is known.

Thoughts? t

Ian Deary who is the leading researcher in cognitive epidemiology has always defined the field as one that investigates the predictive validity of IQ for health outcomes, trying to find causal links. CE may also consider other sources and directions of influence, but that's only to rule out confounding factors so as to find what the real role of intelligence is.

Even before the recent changes, this article had very little material on IQ as a predictor of health outcomes, so the changes did not really alter the scope of this article. Rather, the article name now matches the content better than before.--Victor Chmara (talk) 15:15, 11 July 2011 (UTC)
