Obesity Linked to Rise in Stroke Rates in Women


Previously, an analysis of stroke prevalence rates in the United States from 199 to 2004 revealed that middle-aged women (ages 35 to 54) were more than twice as likely as men of similar age to have a stroke. Amytis Towfighi, from the University of Southern California (USA), and colleagues analyzed data from women who participated in selected timeframes of the National Health and Nutrition Surveys (NHANES) study. The team found that 1.79% of women ages 35 to 54 who participated in the more recent NHANES study years, versus 0.63% in the earlier survey. The researchers further observed that women in the more recent study were "significantly more obese than women a decade prior," with increased BMI (28.6 versus 27.1) as well as waist circumference (4 centimeters greater), and higher glycated hemoglobin (an indicator of poor blood sugar control).

Abdominal obesity is a known predictor of stroke, especially in women, and extra pounds may be a key factor in the surge in the rates of midlife stroke in this population. This study underscores the importance to intensify efforts to curb the obesity epidemic
