Merge?

I think this article should be merged with, or redirect to bone mineral density.

I think it should be merged with Dual energy X-ray absorptiometry. —The preceding unsigned comment was added by 195.10.45.155 (talk) 14:45, August 22, 2007 (UTC)

unit problem...

I think the BMD is express is g/cm² and the BMC is in g. http://hypertextbook.com/facts/2002/AnnaYarusskaya.shtml

yes, someone please correct it?

Bone Density Improvement

It would be helpful if discussion could be presented as to what steps can be taken to improve bone density. (Something beyond drinking milk)

Or at least a link to a site where such info could be obtained.

Why important?

I came to this page to read, why is bone density relevant, and haven't found an answer. Is it considered good to have high bone density? I would imagine the body gets heavier, making it more difficult to do certain activities (like lifts in dance or other performing arts).

Commentor (talk) 19:01, 4 May 2010 (UTC)[reply]

Good question. I rewrote the intro to answer it. alteripse (talk) 02:55, 5 May 2010 (UTC)[reply]

Math

"Normal is a T-score of -1.0 or higher" Um, don't you mean lower? --Palbert (talk) 13:39, 1 October 2010 (UTC)[reply]

Actual density

Is there any sort of number for the actual density of bone, like mass/volume? Or at least the average? --71.229.74.0 (talk) 23:23, 14 November 2011 (UTC)[reply]

    In general, the article would be greatly enhanced by providing the values (in g/cm2) of the norms (which define the T scores) and ranges for the four standard bones used to check for osteoporosis (spine, femur neck, femur total, and forearm radius).  RAWBits4 (talk) 16:58, 5 April 2016 (UTC)[reply]

I came to this page expecting to see numbers for the density of bone in gm/cm^3. I understand that osteoporosis is important but the page is titled "Bone Density". 174.125.235.219 (talk) 16:33, 15 February 2017 (UTC)[reply]

Dietary - behavioral ways to improve bone density

I'd love if someone competent would add such information, which is imo the most important. Possible factors: Sunlight exposure, Vitamin D intake (integrators), weightlifting, and others that i don't know. — Preceding unsigned comment added by 95.244.204.139 (talk) 11:20, 22 May 2012 (UTC)[reply]

I like to see this diet info added too. — Lentower (talk) 23:08, 26 November 2017 (UTC)[reply]

Square or cube?

Bone density (or bone mineral density) is a medical term normally referring to the amount of mineral matter per square centimeter of bones.[

Wouldn't this be 'per cubic centimeter'? Bones are 3d objects so would be measured in quantity cubicly, I don't think you can measure bones in square because it's not a flat plane. Only 3-dimensional objects have mass. Ranze (talk) 21:53, 12 March 2014 (UTC)[reply]

[No - X-ray attenuation (DEXA) gives only an areal bone density. You don't know what the "z" dimension is and so cannot compute a specific gravity. But it can be done -- see https://www.galileo-training.com/at-deutsch/literaturdownload.html?f=lit210.pdf. RAWBits4 (talk) 19:11, 5 April 2016 (UTC)[reply]

So it isn't really density. It's a figure of merit that one hopes is roughly proportional to density. That's fine, but you should make it clear that you are using the phrase "bone density" as a medical term of art rather than in the engineering sense of density. It might also be useful to some people (me, for example) to add a table of actual bone densities. 174.125.235.219 (talk) —Preceding undated comment added 16:41, 15 February 2017 (UTC)[reply]

add info on drugs that treat low bone desnity

This article needs a section on the drugs that treat low bone desnity. Including their effectiveness. — Lentower (talk) 23:10, 26 November 2017 (UTC)[reply]

add info on effectiveness of exercise to improve bone density

This article needs a section on the effectiveness of different kinds og exercise to improve bone density. — Lentower (talk) 23:11, 26 November 2017 (UTC)[reply]

Overtesting and treatment

The section "Overtesting and treatment" addresses neither. — Preceding unsigned comment added by 2600:1000:B10D:6B53:0:67:FDD1:1201 (talk) 20:45, 3 March 2018 (UTC)[reply]

Wiki Education assignment: UCSF SOM Inquiry In Action-- Wikipedia Editing 2022

This article was the subject of a Wiki Education Foundation-supported course assignment, between 8 August 2022 and 20 September 2022. Further details are available on the course page. Student editor(s): Pdh1997, TomasAlamin (article contribs). Peer reviewers: Rwile, Carlosr97, Rballena, Cindyf99.

— Assignment last updated by Rballena (talk) 21:53, 16 September 2022 (UTC)[reply]

Rwile Peer Review: This article is laid out in a very clear manner, and it was very easy to follow!

For the prevention section, it may be helpful to have subsections such as micronutrients (with information on calcium and vitamin D intake), exercise (with information on weight-bearing and resistance exercises), and pharmacological therapies (with information on estrogens, bisphosphonates, etc.). I think sectioning it out in this way may allow you to include more detailed information on the different types of low bone density prevention strategies.

For the Genetic Diseases Associated with Bone Mineral Density section, I would include more of a description of some of the diseases or hyperlink the Wikipedia pages for the diseases so readers are able to see or easily access further details about Osteogenesis Imperfecta, Osteoporosis Pseudoglioma Syndrome, etc. Also, make sure to add in the citation for the sentence, "Because of the heritability of Bone Mineral Density, family history of fractures is considered as a risk factor for osteoporosis."

Overall, this article gave a great overview of the relevant topics to bone density. I think prevention strategies and genetics related to bone density were great choices for additions to the article. Great job! — Preceding unsigned comment added by Rwile (talk • contribs) 04:37, 16 September 2022 (UTC)[reply]

Carlosr97 Peer Review: I thought the genetics and prevention factors you wrote were excellent additions to the article as they can provide valuable education especially to those who are looking to learn about how their own bone density has been affected by modifiable and inherited factors.

In the prevention section, when mentioning exercise, consider comparing these exercise regimens to data about how sedentary lifestyles may lead to reduced bone density (if such research is available).

For the diet section of prevention, listing some foods/diets that do contain an adequate amount of minerals for bone health would be helpful when comparing to vegan/vegetarian diets.

For the genetics section, adding a column for incidence/prevalence would add more info about epidemiology of these genetic conditions.

Overall great job :) — Preceding unsigned comment added by Carlosr97 (talk • contribs) 06:16, 16 September 2022 (UTC)[reply]

Rballena Peer Review: Positive feedback: - I appreciate you adding the section of genetics because it is much needed for this topic. Great job on using high impact review articles as your first references. - Your table is very well designed and your two sources for this topic are credible.

Constructive feedback: - You wrote "(cite from risk factor paper above)" at the end of a sentence. Thoughts on possibly just including the citation? and taking out the parentheses. - For the table, thoughts on including a legend or at least some explanation somewhere that AR = autosomal recessive? I think it could help readers who don't automatically know what AR signifies understand what it means if you put AR = autosomal recessive. — Preceding unsigned comment added by Rballena (talk • contribs) 22:31, 16 September 2022 (UTC)[reply]

Cindyf99 Peer Review: The additional information on diet, risk factors, and genetics is very helpful and detailed. One suggestion I have is a broad overview of the types of bone disease (eg brittle bone disease for OI and soft bone disease for rickets). The prevention section also notes the use of estrogen in maintaining bone density, so it'd be interesting to see how hormonal treatments such as HRT affect BMD long-term. Overall, these edits were well-sourced and helpful in learning more about BMD. — Preceding unsigned comment added by Cindyf99 (talk • contribs) 15:56, 17 September 2022 (UTC)[reply]
