ABSTRACT To evaluate whether the adult smoking rate changed in Lexington-Fayette County, Kentucky, following the enactment of a smoke-free public places ordinance.
Behavioral Risk Factor Surveillance System (BRFSS) data from 2001-2005 were used to test whether smoking rates changed in Fayette County from the pre- to post-law period, relative to the change in 30 Kentucky counties with similar demographics. The sample consisted of 10,413 BRFSS respondents: 7139 pre-law (40 months) and 3274 post-law (20 months).
There was a 31.9% decline in adult smoking in Fayette County (25.7% pre-law to 17.5% post-law). In the group of 30 Control counties, the rate was 28.4% pre-law and 27.6% post-law. Controlling for seasonality, time trend, age, gender, ethnicity, education, marital status, and income, there was a significant Time (pre- vs. post-law) by Group (Fayette vs. Controls) interaction. There were an estimated 16,500 fewer smokers in Fayette County during post-law compared to pre-law.
There was a significant effect of smoke-free legislation on adult smoking rates.

    ABSTRACT: Smokeless tobacco (SLT) use is associated with specific adverse health effects. Knowledge of student tobacco use, including SLT, may guide inquiry into other risky health behaviors, and provide opportunities for health education of students. An incentivized email invitation to complete a web-based survey was sent to students at 11 colleges and universities in North Carolina and Virginia. In autumn 2010, emails were sent to all first-year students (n=29,536) at 11 colleges and universities in North Carolina and Virginia, inviting them to participate in a brief web-based survey to be used to establish a cohort for the parent study evaluating tobacco use over 4 years. Survey items elicited demographic characteristics, tobacco use and other health behaviors. A total of 10,520 (36%) students responded. Past 30 day smoking and SLT use were 12% and 3%, respectively. Logistic regression analysis revealed that male gender (Adjusted Odds Ratio [AOR] = 11.6, 95% Confidence Interval [CI] = 8.16-16.59); current smoking (AOR = 5.5, 95% CI = 4.21-7.10), ever use of alcoholic energy drinks (AOR = 4.8, 95% CI = 3.63-6.43), and ≥ 5 days vs. < 3 days of physical activity a week (AOR = 1.5, 95% CI = 1.07-2.01) predicted risk of past 30 day SLT use. While SLT use is relatively uncommon, knowledge of significant correlations between student tobacco use, including SLT and other risky health behaviors, might guide clinicians' inquiry and provide opportunities for health education of students.

    ABSTRACT: Secondhand smoke (SHS) is a leading cause of childhood illness and premature death, especially in rural areas. The study examined the relationship of having a smoke-free home, strength of smoke-free law (SFL) in the county of residence, having one or more minor children in the home, rural/urban location, and demographics. An Internet-based panel survey was administered to Kentucky residents from 2007 to 2012. Sample size ranged from 400 to 513 per year; N = 2,653 total. Most were female, aged 35-54, had at least some college education, and a smoke-free home. Almost half lived in a county with a comprehensive SFL; 14% lived in a county with a moderate or weak law. Multivariate logistic regression revealed that the significant predictors of a smoke-free home included having education beyond high school, being a nonsmoker, living in an urban county, and year of participation in the survey. Controlling for smoking status and other personal characteristics, those who responded to the survey in the last 2 years of administration were more likely to have a smoke-free home compared to the reference year of 2007. Respondents living in urban counties were nearly 2 times more likely to report a smoke-free home than rural dwellers. Smoke-free homes in urban areas, where SFLs may be the norm, may be more typical than in rural communities. Public awareness campaigns and education about the benefits of smoke-free homes is needed, especially in rural areas, targeting smokers, those with less education, and those with children living in the home.
