Tape measure helps gauge heart risk

Impediments to greater use may include the time required, uncertainty about who should take the measurements, and a lack of familiarity with methods, Iglar suggested. That’s why waist circumference is important to watch for the 65 per cent of Canadians adults who are overweight or obese. A tape measure around the waist helps show who is at risk for heart disease beyond standard body-mass measurements, but not all family doctors are routinely using it. 94 centimetres (37 inches) for most men. For some reason, I never thought of it that way before, and it kind of gave me a visual as to ‘That can’t be good. Those risks explain why Canadian family doctors are encouraged to watch their patients’ waistlines. It might lead to lifestyle interventions at an earlier stage than with BMI alone. When your waist circumference is bigger, all that fat is around all your organs, said Grant Barber, who is participating in a study on weight loss through exercise at Queen’s University in Kingston, Ont. Scientists are learning more about how the deep abdominal fat that surrounds vital organs is worse than fat just beneath the skin in terms of risk of developing heart disease, Type 2 diabetes and other obesity-related illnesses.
Using waist circumference alongside BMI helps doctors, nurses, dietitians, kinesiologists and psychologists to tease out who is in greater need of weight-loss counselling, said Prof. It would put people potentially in a different risk category if their waist circumference was above the cutoff, said Dr. Research suggests that if the waist circumference climbs to more than 102 centimetres (40 inches) for most men or more than 88 centimetres (35 inches) for women then the risk of Type 2 diabetes, coronary heart disease, and other obesity-related illness also rises. Since a healthy diet and exercise can shrink the waist while weight stays the same, a smaller waist circumference may reflect health improvements from lifestyle changes that might otherwise be abandoned by those discouraged by numbers on the scale that barely budge, Ross said. 80 centimetres (31. 5 inches) for women. While it’s simple for doctors to wield a tape measure alongside their prescription pads, there is room to improve on their use of the tool, said Iglar, who developed the checklist.

In 2007, waist circumference became part of a preventive care list for family doctors in Canada — a checklist for physicians to use during checkups for adults that also includes measures like colonoscopy and hepatitis B screening.
