The waist circumferences provided look too low for the equivalent BFs. “True” 31-inch waists are not very common among men. The relatively short follow-up period, of 8.8 years, led to too few deaths being recorded – e.g., 470, from a total sample of 6171. These are among the problems that I’ve noticed right away.Ned Kockhttps://www.blogger.com/profile/02755560885749335053noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-12225672530996794932013-06-20T09:10:48.804-07:002013-06-20T09:10:48.804-07:00Patrick,

Thanks.<br /><br />The table for waist measurements indicates a dramatic reduction in risk for the major "cardiometabolic" diseases associated with waist circumference < 79.9cm (~31.5inch) for men. <br /><br />It's not clear to me how "waist circumference" was measured.<br /><br />Is there a clinical standard practice for measuring waist circumference, I wonder? Searching on line brings up a few directions, all seemingly error prone (eg. taken at or one inch above the navel? or the narrowest circumference? at the top of the hip bone?).<br /><br />And how did you extract that 46% ratio for waist/height from the data presented?<br /><br />Patrick<br /><br /><br />Patrick Snookhttps://www.blogger.com/profile/10587563992062414001noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-54019862560620258412013-06-19T14:34:05.148-07:002013-06-19T14:34:05.148-07:00David

My current ratio of 0.1882 inches/pound (~12% body fat) is the lowest of all. My highest was 0.2044 inches/pound (~22% body fat) a few years ago. Body fat was based on the US Navy Circumference Method.<br />I wish I had data going back another decade when I was 30 pounds heavier.taphttps://www.blogger.com/profile/10496485747177537600noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-25435888823675330782013-06-19T02:44:25.203-07:002013-06-19T02:44:25.203-07:00Thanks, Ned, I'll keep reading.
