NEWS YOU CAN USE: How Exercise Can Help You Live Longer. Independently, it seems, of its effect on cholesterol, weight, etc.
More surprising, when the researchers controlled for each volunteer’s Framingham risk score and waist size, they found that exercising still significantly reduced people’s risk of dying from heart disease. The benefits were fainter, amounting to about half as much risk reduction as before adjustment for these health factors. But they accrued even among volunteers who had less-than-ideal blood pressure, cholesterol levels or waistlines. Someone with a high Framingham score who exercised had less risk of dying than someone with a similar score who did not.
The study’s results do not suggest, of course, that any of us should now willfully ignore cholesterol or other standard risk factors when considering heart health, said Satvinder Dhaliwal, a professor at Curtin University, who with Timothy Welborn and Peter Howat, conducted the study. But the data does suggest that “identifying and increasing physical activity” may be “at least as important as the measurement and treatment of lipids and hypertension,” he said.
So now doctors should not only talk to patients about diet — something most doctors aren’t very good at — but also about exercise, something most doctors are even worse at. . . . Still, an interesting finding.
