A new study published in the Journal of the American Heart Association aimed to assess the association between breastfeeding and stroke and whether this association varies with race and ethnicity. This study included data on 80,191 parous postmenopausal women from the Womens Health Initiative Observational Study with follow-up through 2010. Of these women, 3.4% had experienced a stroke within a follow-up period of 12.6 years. The results showed that 53% of the patients reported to have breastfed in the past; 83% were non-Hispanic whites; 8% were non-Hispanic blacks; 4% were Hispanic; and 5% were of other race or ethnicity. When compared to women who had never breastfed, women who reported to have breastfed had a 23% lower risk of stroke, while this association was the strongest for non-Hispanic black women. In addition, breastfeeding for a short duration (1-6 months) was associated with a 19% lower risk of stroke. This association seemed stronger with a longer duration of breastfeeding and among non-Hispanic white and non-Hispanic black women. Thus, an association and dose-response relationship between breastfeeding and lower risk of stroke among postmenopausal women could be established after adjustment for multiple stroke risk factors and lifestyle variables. It was stated that this finding warranted further investigation.
