Preterm birth and maternal smoking: risks related to gestational age and onset of delivery

Article Abstract:

Spontaneous preterm birth is associated with maternal smoking, and risk increases with the amount smoked. Data from the Swedish Medical Birth Register on live singleton births between 1991 and 1993 were used in the study, constituting a study population of 311,977 births. The greatest effect of smoking was related to risk of very preterm birth, defined as a gestational age of less than or equal to 32 weeks. Smoking is also associated with spontaneous rather than induced preterm birth.

Will an adverse pregnancy outcome influence the risk of continued smoking in the next pregnancy?

Article Abstract:

A nationwide Swedish study is conducted to find out whether smoking habits in subsequent pregnancies were in any way related to smoking-related pregnancy outcome during the first pregnancy. The results suggested that there was only a modest reduction among women with severe adverse pregnancy outcomes, which means that the existing smoking interventions during pregnancy are insufficient and additional public health campaigns and more patient-centered strategies are required.
