Because of the study’s observational design, the results “cannot show that antibiotics cause heart disease and stroke, only that there is a link between them,” Dr. Qi said. “It’s possible that women who reported more antibiotic use might be sicker in other ways that we were unable to measure, or there may be other factors that could affect the results that we have not been able take account of.”
“Our study suggests that antibiotics should be used only when they are absolutely needed,” he concluded. “Considering the potentially cumulative adverse effects, the shorter time of antibiotic use the better.”
The study was supported by National Institutes of Health grants, the Boston Obesity Nutrition Research Center, and the United States–Israel Binational Science Foundation. One author received support from the Japan Society for the Promotion of Science. The authors had no conflicts of interest.
