Minnesota: Shorter and Longer Sleep Durations Linked to Heart Health Risk in Older Women

Researchers with the University of Minnesota School of Public Health recently completed two studies that reveal how sleep duration is associated with heart health in older women. The studies were led by postdoctoral research fellow Dr. Kelsie Full and and published in The Journals of Gerontology: Series A and Sleep.

Both studies examined measures of cardiovascular health and sleep behavior among a diverse group of more than 3,000 post-menopausal women participating in the larger Women’s Health Initiative Study. 

In The Journals of Gerontology study, the researchers looked at how the women’s average sleep duration related to a predictor of future cardiovascular health risk, called the Reynolds Risk Score. 

The study found: 

In the second study, published in Sleep, Dr. Full and the research team examined how sleep duration was associated with various cardiovascular and metabolic health measures, including body mass index (BMI) and total cholesterol. The study also evaluated how hypothetically altering the amount of time spent sleeping, sedentary or physically active each day changed the values of the measures.
