Low-dose aspirin may reduce preterm birth risk among first-time mothers: study

Daily low-dose aspirin, from as early as the sixth week of pregnancy through the 36th week, may lower the risk for preterm birth among first-time mothers, suggests a study funded by the National Institutes of Health. The clinical trial, which involved more than 11,000 women in several low- and middle-income countries, found that women taking daily low-dose aspirin were 11% less likely to deliver before the 37th week of pregnancy, compared to those given a placebo.
