The article, “A Citywide Smoking Ban Reduced Maternal Smoking and Risk for Preterm, Not Low Birth Weight, Births: A Colorado Natural Experiment,” is available free on the Journal of Women’s Health website.
According to the authors, prenatal exposure to tobacco smoke–whether the mother is a smoker or exposure is from environmental sources—is associated with premature births and low birth weight. The results of a “natural experiment” that compared outcomes in two cities, one with a smoking ban and one without a ban, showed reductions in both maternal smoking and premature births in the city with a smoking ban.
The article concluded that a population-level intervention using a smoking ban improved maternal and fetal outcomes.
