Those methods, he said, include doing the measurements in private rooms or letting patients measure their own waistlines with inexpensive digital measuring tapes.
Rao said, "I think this study points to BMI as a flawed measure and offers evidence that we ought to be measuring waist circumference systematically in all of our adult patients at least once a year — not just because it shows certain people they are at high risk, but it might also identify folks that are not at high risk. Peters said more research is now needed into the different ways women and men store body fat and how that affects overall health.
Rao called for additional research into how waist circumference affects stroke risk, and how it impacts various racial and ethnic groups. In the meantime, Rao said the study reinforces the need for both men and women to decrease excess belly fat with a two-pronged approach of proper nutrition and regular exercise.

List of Partners vendors. Almost everyone knows by now that being overweight or obese substantially increases your risk of developing cardiovascular disease, including coronary artery disease CAD , heart attack , and stroke. The three most commonly used measures are BMI body mass index , waist circumference, and waist-to-hip ratio.
But is one better than the others? The measure most commonly used to assess weight-related risk is BMI, a ratio calculated from your weight and height. Specifically, your BMI equals your body in kilograms divided by your height squared in meters. A BMI of BMI calculators are easy to use all you need is your height and weight and are readily available online.
The BMI is useful because this measurement has been employed in numerous clinical studies, so lots of analysis has been done with the BMI measure. However, BMI is not always accurate in every individual. It overestimates body fat in people with a lot of muscle mass and tends to underestimate it in elderly people who often lose muscle mass. This is because abdominal obesity correlates with an increased risk for not only cardiovascular disease, but also metabolic syndrome , hypertension , and diabetes.
Studies have shown that a waist circumference of 40 inches or more cm in men, and of 35 inches or more 88 cm in women, is associated with elevated cardiovascular risk. The waist-to-hip ratio is another way of assessing abdominal obesity, and studies have confirmed that this measure correlates with cardiovascular risk. In women, the ratio should be 0. This means that in women the waist should be narrower than the hips, and in men, the waist should be narrower or the same as the hips.
The waist-to-hip ratio is helpful because in smaller people waist circumference alone may underestimate risk. By comparing waist circumference to hip circumference, you can get a better indication of abdominal obesity. There is no definitive answer to this question.
People with a normal Body Mass Index BMI who carry their weight around the middle are at the highest risk of death from any cause and cardiovascular causes compared to these who are obese according to BMI but carry their weight elsewhere, a new study co-led by University of Sydney researchers shows. Published today in the Annals of Internal Medicine , the study shows that normal weight people who carry fat around the middle of their body are 22 per cent more likely to die from any cause and a 25 per cent higher risk for death from cardiovascular causes compared to those who are classified as normal weight without carrying fat centrally.
Associate Professor Stamatakis says there are a range of reasons as to why fat carried centrally can lead to an increased risk of death. Associate Professor Stamatakis says those with larger waistlines are best advised to see their doctor to understand how to best lose excess weight.
