Smoking behaviour, cessation attempts and the influence of parental smoking in older adult women: a cross-sectional analysis from Italy

The overall prevalence of current smoking was 15.6% (n=1516), and that of former smoking was 13.2%. Women whose parent(s) smoked were more likely to be current smokers, especially if only the mother smoked (adjusted odds ratio 4.27; 95% confidence interval 2.24-8.12). Other factors significantly associated with current smoking in the multivariate analysis were younger age, lower body mass index, higher level of education, unmarried status, and exposure to ETS either inside or outside the family environment. Eighteen percent of all current smokers were non-inhalers, and more than 60% of ex-smokers quit smoking on their first attempt. Our findings expand the existing evidence suggesting that a strong effect of parental conduct on a daughter's smoking behaviour may persist throughout life. Although more research is needed, especially to clarify the role of genetic and environmental factors in determining the mother-child smoking association, our results suggest that intensifying smoking prevention efforts directed at women with children might considerably reduce the risk of ever smoking in future female generations.
