Women With Insomnia Over Midlife at Higher Risk for Incident CVD

Insomnia symptoms and short sleep duration are linked to an increased risk of cardiovascular disease (CVD) in women. The Study of Women’s Health Across the Nation (SWAN) gathered data from over 2,900 women aged 42 to 52 over a 19-year period. Participants with persistent high insomnia had a higher risk of CVD, as did those with persistently short sleep. A joint analysis found that high insomnia symptoms with short or moderate sleep were also associated with CVD risk. Self-reported sleep symptoms were a limitation of the study. Researchers stress the importance of considering sleep in assessing women’s CVD risk.
