Voluntary home smoking ban: prevalence, trend and determinants in Italy.

To investigate voluntary home smoking bans, we analysed five nationally representative surveys on 15 175 adults conducted in Italy in 2011-2015. Overall, 61% of Italians (69% of non-smokers and 32% of current smokers) adopted a complete home smoking ban. Although families with children more frequently live in smoke-free homes, still the majority of current smokers living with children admit smoking inside their homes. Complete home smoking bans are substantially increasing in Italy, and an acceleration of this trend is expected with the 2016 implementation of a new tobacco control legislation aimed at decreasing the social acceptability of smoking.
