High A1Cs Raise Women’s Stroke Risk
Poor blood glucose control is linked to a greater risk for stroke in women—but not men. That’s what researchers found when they studied more than 30,000 adults with newly diagnosed type 2 diabetes. Women with higher A1Cs were more likely to have a stroke during nearly seven years of follow-up than those with in-range levels. Compared with women whose A1Cs were between 6 and 6.9 percent, women with A1Cs between 9 and 9.9 were 32 percent more likely to have a stroke. Women whose A1C hit 10 percent or above had a 42 percent higher stroke risk. The association was stronger in women over 55 years old. The link between higher blood glucose and stroke risk wasn’t significant in men, but previous research has shown that a high A1C increases their heart attack risk.
