County Smoking Bans in Bars, Restaurants Cut Asthma-Related Hospitalizations
Expanding smoke-free laws in bars or restaurants may be more impactful in preventing asthma-related hospitalizations than smoke-free laws in nonhospitality workplaces, according to a study published online May 14 in the Canadian Respiratory Journal.
While the majority of nonhospitality workplaces (e.g., office buildings) are covered by either public or private smoking bans, only about half of the U.S. populations lives in places where 100% smoke-free laws are in force in all workplaces, including bars and restaurants.
Previous research on the impact of smoke-free laws has focused on state laws. In the present study, the researchers examined multistate, county level data using Healthcare Cost and Utilization Project (HCUP) state inpatient data (2002 to 2009) in combination with the American Nonsmokers’ Rights Foundation’s smoke-free laws database of state and county laws.
In total, data from 17 states was included in the analysis (12 states with state smoke-free laws and five states without state smoke-free laws). These 17 states represented approximately 103 million people, or 35 percent of the U.S. population living in 840 counties. Twenty-nine counties, included in the study, passed a county-level clean indoor law during the study period, 16 counties already had a county-level nonhospitality workplace law in place, and 20 counties already had a county-level restaurant or bar law in place.
Overall, the researchers found that asthma-related hospital discharges were not reduced by enacting smoke-free workplace laws within county jurisdictions. However, enacting smoke-free restaurant and bar laws was tied to reductions in asthma discharges.
“Only 49% of the U.S. population lives in a location where smoke-free laws are in force in all bars, restaurants, and workplaces,” says lead author Glenn Landers, Sc.D., director of health systems at the Georgia Health Policy Center. “Clearly, there are still opportunities to reduce second hand smoke exposure and health outcomes through changes in county smoking laws.”
