Guest guest Posted June 26, 2004 Report Share Posted June 26, 2004 Hi Al: Thanks for that reference. And now I think about it, I can see the sense in it. The problems we recognize with BMI are that muscular or heavy-boned people may appear to have an excessively high BMI. But there is no good reason why such people would be expected to have elevated health risks of the type associated with obesity. But then heavy-boned or muscular people, while having a high BMI, will not have a materially higher waist circumference, in comparison with those who have a high BMI because of excess fat tissue. So it makes a lot of sense that some measure of circumference (waist? abdomen?) would be better correlated with obesity-type health problems than BMI. Quite funny really. Everyone these days is supposed to go to the trouble of converting their data for height and weight to metric, and then remember which is to be squared, and which of them is supposed to be the numerator and which the denominator, then find a calculator and do the calculation. Whereas they could, instead, get a superior indication of what they want to know in a couple of seconds by just taking one simple measurement with a tape measure - no calculations!

Guest guest Posted June 26, 2004 Report Share Posted June 26, 2004 But recognize that "belly" fat is maybe visceral as well as adipose. I'm not sure if it's saying the adipose fat on the belly is diff from the adipose fat on the hips. The visceral seems to come out easily. Not so the adipose. I got the waist down to 38.5" but I'm stumped how to get that 5# slab on the surface off.

Guest guest Posted June 26, 2004 Report Share Posted June 26, 2004 Yes Al the 'apple/pear' comparison has been around for quite some time as I recall. Here's a quote from this weeks 'Forbes Magazine' about heart attacks and cholesterol. Home > Magazines > Forbes Global Ê Attacking Heart Attacks Langreth, 06.21.04 Heart disease kills an estimated 17 million people a year worldwide. Scientists are designing a new arsenal of weapons that could conquer this killer in our lifetime. By the Numbers Critical Care Heart disease wreaks a devastating toll. Ê 13,200,000 Americans have heart disease. 865,000 Americans suffer heart attacks each year. 696,000 Die from heart disease. $133.2 billion Annual cost of treating heart disease. 28.5% Of adults have high cholesterol. 26.7% Have high blood pressure. Sources: American Heart Association; Centers for Disease Control.In his own small way an icelandic former carpenter named Asgeir Arnason has contributed to a startling turn in the medical assault on heart disease. For decades doctors and scientists obsessed over one key factor in heart attacks--high cholesterol--and devised drugs to treat it. But in recent years their understanding of heart disease has shifted to focus on an entirely new front: inflammation of the arteries. Arnason, age 48, helped. As early as age 22 he complained of stabbing chest pains; in 1992, at age 36, he survived a massive heart attack. He spent seven years recovering, and in that time his mother, a sister and a first cousin also had heart attacks; the cousin's was fatal. Convinced something more than high cholesterol was at work, Arnason and his father gave blood samples in 2000 to DeCode Genetics, a biotech firm in Reykjavik that uses Iceland's isolated population to search for disease-causing genes. DeCode researchers spent four years analyzing the DNA of the Arnasons and thousands of other Icelandic heart patients, unearthing a couple of key suspects:two gene variants, previously thought to be involved in asthma, that nearly double the risk of heart attack by boosting levels of a molecule that promotes inflammation of the artery walls. On the basis of this discovery,DeCode recently began human trials of an old asthma drug that counteracts the bad genes, hoping this will slash heart attack risk. Boasts DeCode founder and Chief Kari Stefansson: " If this holds up, it could match the importance of the discovery that high cholesterol predisposes [one] to heart attacks. " " There's a sea change in how doctors think about cardiovascular disease, " says Harvard cardiologist Ridker, a pioneer in studying artery inflammation. " It's not just about cholesterol anymore. " This radical rethinking is part of an intensifying attack on heart disease, one that could, in our lifetime, neutralize the most lethal killer of Americans. Heart attacks hit 865,000 people in the U.S. each year; and heart disease kills an estimated 17 million worldwide annually (696,000 in the U.S.). Half of all men in the U.S. will get heart disease. Despite powerful new drugs, fully 64% of American adults have high cholesterol or other risk factors, up from 58% in 1991. " We're losing the lifestyle war, " says Libby, chief of cardiovascular medicine at Brigham & Women's Hospital in Boston. Now academic researchers, drug giants and fledgling biotechs are opening up a new arsenal: genetic tracking to isolate flawed genes; new drugs to quell inflammation or raise " good " cholesterol; and new techniques to inspect plaque inside the arteries. The race is on to uncover the key molecular triggers of artery inflammation and develop ways to detect and treat it before it does fatal damage. Virtually every drug firm, including Glaxokline, Novartis and & , is working on some method of limiting inflammation. Pfizer, Eli Lilly, Bristol-Myers Squibb, AstraZeneca and others are testing drugs that would reduce inflammation indirectly by raising the " good " HDL cholesterol that helps the body pump fat out of the arteries. " Atherosclerosis is very much an inflammatory disease, and that's where all the future therapies are going, " says Colin Macphee, a Glaxokline biologist. Adds Aldons Lusis, who studies atherosclerosis at UCLA: " Every major drug company is thinking about it. " Ultimately, cardiologists hope to create a powerful new triple-threat cocktail combining today's statin drugs for lowering bad cholesterol (like Lipitor) with new compounds to boost good cholesterol and other drugs that would directly reduce vessel-wall inflammation. All of this, some researchers speculate, might prevent 75% of all heart attacks. " We are getting at the roots of the disease process, " saysCleveland Clinic cardiologist Nissen, who is testing many of the new drugs. " Can we roll the clock back on atherosclerosis? It is a dream, but I think it is a dream that is about to come true. " At the heart of the new assault is the radical view that heart attacks don't result simply from blood vessels clogged with fatty cholesterol plaques--that instead they may arise from an immune system gone haywire trying to remove the cholesterol. Immune cells called macrophages, trying to clear the mess, eventually choke and die, worsening the situation. Inflamed with immune cells, the resultant unstable plaques are prone to rupture like a volcano at any time, spewing toxic fat globs into the bloodstream and triggering deadly clots, causing cardiac arrest. The inflammation theory helps explain why even someone with low cholesterol can have a heart attack, and why so many patients with no previous symptoms can suddenly be struck down. The plaque that bursts isn't necessarily the one that blocks arteries and causes symptoms. " Atherosclerosis is not a killer. Almost all Americans over age 50 have plaque " in the arteries, says Topol, chairman of cardiovascular medicine at the Cleveland Clinic. " What kills people is the cracking of the arteries.
