A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to have
with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of having preterm labor. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
Non-white women under the 18 years or over 35 years have an increased risk of preterm labor. Other factors that may increase your risk include:
Exposure to diethylstilbestrol (DES)—Before its dangers were known, DES was given to pregnant women to decrease the risk of miscarriage; if your mother took DES while she was pregnant with you, your reproductive organs may be damaged. DES has not been used since the 1970s.
