Women who were postmenopausal and breastfed had a decreased risk for stroke, according to a study published in the Journal of the American Heart Association.
“Breastfeeding is only one of many factors that could potentially protect against stroke,” Lisette T. Jacobson, PhD, MPA, MA, assistant professor in the department of preventive medicine and public health at the University of Kansas School of Medicine-Wichita, said in a press release. “Others include getting adequate exercise, choosing healthy foods, not smoking and seeking treatment if needed to keep your blood pressure, cholesterol and blood sugar in the normal range.”
Researchers analyzed data from 80,191 women (median age, 64 years) from the Women’s Health Initiative
Observational Study who were postmenopausal and parous at baseline.
Questionnaires were completed to collect data on reproductive history,
demographic information, medication use, lifestyle behaviors, and
personal and family medical history. Women were then categorized by ever
breastfed or never breastfed.
The primary outcome of interest was the incidence of stroke between the birth of their first child and the end of follow-up, which was conducted for a median of 12.6 years.
During follow-up, 3.4% of women had a stroke. In addition, 58% of women reported ever breastfeeding.
After adjusting for nonmodifiable risk factors, women who breastfed for 1 month or longer had a reduced risk for stroke compared with those who never breastfed (HR = 0.77; 95% CI, 0.7-0.83). This link was strongest in non-Hispanic black women (HR = 0.52; 95% CI, 0.37-0.71).
The risk for stroke was also lower in women who breastfed for 1 month to 6 months vs. those who never breastfed (HR = 0.81; 95% CI, 0.74-0.9). The relationship was stronger in women who breastfed for longer (P for trend < .01). The strongest association was seen in non-Hispanic white and non-Hispanic black women (P for trend < .01).
“The effectiveness of these types of interventions should be investigated in future studies,” Jacobson and colleagues wrote. “Increasing public awareness of the potential impact of breastfeeding on maternal health outcomes later in life may assist in the initiation and continuation of breastfeeding for those at greatest risk.” – by Darlene Dobkowski
