State-specific secondhand smoke exposure and current cigarette smoking among adults - United States, 2008.
Secondhand smoke (SHS) causes immediate and long-term adverse health effects in nonsmoking adults and children, including heart disease and lung cancer, and SHS exposure occurs primarily in homes and workplaces. Smoke-free policies, including not allowing smoking anywhere inside the home (i.e., having a smoke-free home rule), are the best way to provide protection from exposure to SHS. To assess SHS exposure in homes and indoor workplaces and the prevalence of smoke-free home rules, CDC analyzed 2008 Behavioral Risk Factor Surveillance System (BRFSS) data from 11 states and the U.S. Virgin Islands (USVI). This report summarizes the results, which showed wide variation among states in exposure to SHS in homes (from 3.2% [Arizona] to 10.6% [West Virginia]) and indoor workplaces (from 6.0% [Tennessee] to 17.3% [USVI]). The majority of persons surveyed in the 11 states and USVI reported having smoke-free home rules (from 68.8% [West Virginia] to 85.7% [USVI]). This report also provides the 2008 results for CDC's annual BRFSS-based state-specific estimates of current smoking in 50 states, the District of Columbia (DC), and three territories (Guam, Puerto Rico, and USVI). As in previous years, the results showed substantial variation in self-reported cigarette smoking prevalence (range: 6.5%--27.4%; median for 50 states and DC = 18.4%). Additional legislation is needed to increase the number of smoke-free workplaces and other public places. Health-care providers should continue to encourage persons to make their homes completely smoke-free.
