Study links smoking bans to fewer pre-term births.
What is already known on this topic

Despite growing evidence that secondhand smoke has a negative impact on pregnancy duration and birth weight, few studies have shown a beneficial impact of smoke-free legislation on pregnancy outcomes

What this study adds

Stepwise implementation of smoke-free legislation in Belgium allowed the demonstration of successive reductions in preterm deliveries which persisted after the implementation of the different legislation phases

The largest reductions in preterm birth coincided with the implementation of the second and the third phase of the legislation (smoking ban in restaurants and in bars serving food, respectively)

Even a small relative decline in preterm deliveries can have important public health benefits
