Women who gave birth to two or three children may have a lower risk of strokes and vascular brain damage, according to a new study.
The findings, published recently in the Journal of the American Heart Association on March 18, 2026, highlight how a woman’s reproductive history can serve as a vital predictor for her long-term neurological health. Because women account for nearly 57% of all stroke deaths in the United States, detecting precise risk factors is a top research priority.
Scholars examined data from 1882 women participating in a project that has tracked the health of over 15,000 residents in Massachusetts since 1948. At the beginning of the new study, the women were an average of 61 years old and had no prior history of stroke.

Over 18 years, researchers monitored them for clinical strokes as well as small areas of damage caused by restricted blood flow that can be seen on a brain MRI but might not cause instant symptoms.
According to an expert at UT Health San Antonio, the findings would suggest that reproductive factors, such as the number of live births, can be an additional factor to consider when evaluating stroke risks in women.
Inclusion of this risk factor, according to the U.S. Centers for Disease Control and Prevention (CDC), may increase risk prediction in women. By understanding these unique reproductive markers, doctors may soon be able to tailor stroke prevention plans specifically for women.
