8 Habits Tied to Lower Diabetes Risk in Postmenopausal Women
A new analysis of the Women’s Health Initiative found that postmenopausal women who score high on the American Heart Association’s Life’s Essential 8 (LE8) framework face a dramatically lower chance of developing type 2 diabetes. Researchers tracked 19,403 women aged 50 and older for an average of 16 years, linking higher LE8 scores to a 57% risk reduction, while a reduced five‑factor version (LE5) still cut risk by 40%. Blood sugar control and body‑mass index emerged as the strongest individual predictors. The findings suggest that heart‑healthy habits can double as powerful diabetes‑prevention tools even later in life.
