John M. Thorpe, Jr. MD and Clarke Forsythe on what the WHO’s document on preterm births leaves out:
Unfortunately, one significant, and modifiable, risk factor for preterm birth was completely ignored by the WHO report: prior termination of pregnancy. There is a large and growing body of scientific data documenting this risk factor for pre-term birth. More than 120 peer-reviewed studies, from more than a dozen countries, have found a statistically significant increased risk of preterm birth or low-birth weight after a termination of pregnancy.
