Public Smoking Bans May Spill Over to Households
TUESDAY, Nov. 8 (HealthDay News) -- Smoking bans in public places have had a spillover effect by reducing smoking in homes as well, according to a new study.
U.S. researchers analyzed data from a nationally representative household survey of tobacco use and found that people who lived in counties with total smoking bans in workplaces, restaurants and bars were more likely to have total smoking bans at home.
Homes with children were most likely to be smoke-free, according to the study appearing online and in the December issue of the American Journal of Preventive Medicine.
"Since the home remains a major source of secondhand smoke exposure for children, this work shows that an additional justification for enacting smoke-free legislation is the secondary effect of encouraging voluntary smoke-free rules at home, particularly in homes occupied by smokers," he concluded.
Another study published in the same issue of the journal found that the rate of total smoking bans in U.S. homes more than tripled from 1992-1993 to 2006-2007. However, only half of households with both smokers and children were smoke-free.
Increases in total smoking bans at home were "smallest among African-American households, and among households with older versus younger children. There were fewer smoke-free households below the poverty line, in households with less education and in states with high smoking prevalence," lead author Karen Messer, professor and director of biostatistics at Moores Cancer Center at the University of California, San Diego, said in the news release.
"Effective interventions to promote smoke-free homes among smoking families are needed, and this study can help identify populations that would benefit from such interventions," she added.
