The reason we did the follow-up (2016 review) was that there was emerging evidence then that smoking bans had impacts on health outcomes. The new review shows much stronger evidence for this in the case of heart disease,” Professor Kelleher says.
With the 2016 update they found: “Along with evidence of improvements in the rate of cardio vascular disease, there were a number of other health outcomes assessed but with fewer studies to date. For instance they looked at perinatal or birth outcomes, showing some evidence of impact on birth weight but as yet less consistently”.
She adds: “We need to build the evidence base on sub-groups of populations. We see that bans are effectively reducing passive smoke exposure, but we would also like to quantify this more clearly to show the economic benefits on the population.”
