Response: Growing data suggest that antibiotic exposure is associated with a long-lasting alteration in gut microbiota, and may be related to subsequent cardiovascular disease (CVD). We investigated associations of duration of antibiotic use in different phases of adulthood (young, middle and late adulthood) with the CVD incidence among women at usual risk.

This new analysis from the Nurses’ Health Study shows that women who take antibiotics for long periods, especially during more recent adulthood (such as  in middle- and late adulthood) had a higher risk of CVD in later life. What should readers take away from your report?

Response: Longer duration of antibiotic use may be linked to higher risk of CVD among women. What recommendations do you have for future research as a result of this work? 

Response: Studies in other populations including male participants would be needed to confirm whether our results are applicable to other populations.
Also, more research focusing on duration of antibiotic use with other metabolic disease outcomes as well as non-cardiovascular events would be important.
