Thanks for responding. Never would have expected it.

The article states:

“Use your hand to feel the bony prominences on the front of your hip and find the highest one, the anterior superior iliac spine (ASIS).
Draw a horizontal line to mark ASIS with cosmetic pencil on both sides.
Place tape measure around waist with the base of the tape measure flush the marked line.”

and also:

“I would recommend feeling for the ASIS and then placing the tape around the area just above that bony projection…”

However, the horizontal mark depicted in Exhibit 3-9 does not appear to be at or even “just above” the location of the ASIS based on my understanding of where the ASIS is located. Using the following image (https://www.wesnorman.com/Images/pelvislateral.jpg) for example as a guidepost, the horizontal mark in Exhibit 3-9 appears to be at the top of the Iliac crest and NOT at or even “just above” the ASIS?

Furthermore, the narration of the video, beginning at 5:10, says:

“At the superior margin of the iliac crest, that’s the highest point that you can palpate…that’s where the bottom of the tape measure will be.”

Again, based on my possibly incorrect understanding, and based on the images that I’ve found and linked in my two comments, placing the tape measure directly above the ASIS and directly above the superior margin of the iliac crest would appear to place the tape measure at two different locations that are several centimeters apart.

I look forward to your clarifying my misunderstanding! Thanks.

The position of the umbilicus (belly button) is irrelevant to the waist circumference measurement and only adds to the confusion. The article and the video are both correct, as you should measure above the ASIS at the top of the iliac crest.

I’m having trouble reconciling the waist measuring instructions in the video to the text of the article. I may be misunderstanding, but it seems the video is recommending to measure above the top of the iliac crest. During your demonstration in the video, the tape goes near your belly button, which is similar to where mine goes when I measure from the same place.

However, the article says to measure above the anterior superior iliac spine (ASIS). According to both Wikipedia (see below) and my potentially mistaken identification on my own body, the ASIS appears to be several centimeters below the top of the iliac crest. Could you clarify from which location is the correct place to measure? Thank you.

All Asians.

That seems reasonable.

Alan’s is way less than 40″, but I don’t have access to anyone else’s waist data besides my own and my clients. You could just ask a person who’s waist you’re curious about. Might be met with some weird stares, of course.

That study is 10 years old and much has been done in the interim. Currently there is no singular value that does what we want it to do. That said, BMI and waist circumference together do a good job and other ratios, calculations, etc. don’t do any better.

thanks for the user manual. I didnt know that and always measured to high. Lets see if that was under- or overestimating…

I think the data says only waist circumference is ok, but indeed waistt/height is a bit better. https://www.ncbi.nlm.nih.gov/pubmed/18359190

Of course, its one more step, making it a bit higher threshold. Although imo for somenone who doesnt mind, or for larger study populations, taking into account the height may make sense to get a bit more validity.
