States with smoke-free laws report fewer asthma symptomsNew research from the American Journal of Public Health finds non-smoking adults are less likely to report asthma symptoms in states that have enacted smoke-free indoor air laws.
Researchers analyzed data from the 2007-2011 Behavior Risk Factor Surveillance System Asthma Call-Back Survey to assess the impact of smoke-free indoor air laws on second-hand smoke exposure, asthma attacks and doctor visits for asthma symptoms. Data from Iowa, Illinois and Maryland, states that had enacted smoke-free indoor air laws in 2008, were compared against data from Texas and West Virginia where no statewide smoking restrictions had been constituted. Understanding that asthma attacks can result from a range of risk factors other than second hand smoke exposure including gender, socioeconomic status, use of indoor combustion devices, pets and mold, researchers controlled for these risk factors to investigate its interactions with secondhand smoke and asthma.
Findings revealed a significant decrease in second hand smoke exposure in states with comprehensive smoke-free indoor air laws. In addition, compared to states with no smoke-free indoor air laws, non-smoking adults had lower odds of reporting asthma symptoms and were also less likely to report fewer doctor visits as a result of severe asthma symptoms in states with such laws in place.
“We have demonstrated the efficacy of the enactment of comprehensive smoke-free indoor air laws in reducing asthma symptoms and the number of doctor visits owing to severe asthma symptoms in a fully adjusted model. Several previous studies support our findings although their samples were not representative of the entire nation,” the authors explain.

For new users, sleeping pills may double car crash riskNew research from the American Journal of Public Health finds that sedative hypnotic medication use could nearly double the risk of motor vehicle crash among new users of the medications.
Researchers developed a cohort study of participants who had a drug benefit through Group Health Cooperative, were between 21 and 79 years old, were Washington state residents and had Washington state driving licenses. The population's medical encounters and prescription records were combined with Washington State driver’s license records and motor vehicle crash records. The researchers sought to understand associations between motor vehicle crashes and three types of sedative agents: temazepam, zolpidem and trazodone.
For new users of all three prescriptions, exposure nearly doubled the risk of motor vehicle crashes. Among the three drugs analyzed, temazepam appeared to offer the least risk. The increased risk could last for a period of up to one year of continuous prescription filling for new users.
“Depending on an individual’s need to drive regularly combined with a medical indication for sedative use, the choice of a particular sedative may affect the risk of crashing. Prescribers, pharmacists and patients should discuss this potential risk and consider the implications of this analysis when selecting a sedative hypnotic medication,” the researchers recommend.

Graphic, risk-oriented warnings may be most effective in limiting indoor tanningMessaging that emphasizes the risk of tanning and contains graphic imagery may be the most effective at helping women decide not to tan, according to new research from the American Journal of Public Health.
Researchers surveyed more than 600 non-Hispanic white women ages 18-30. The survey assessed their responses to five different messages about tanning. One message mirrored the current required FDA warnings; two were gain-framed messages which highlighted the benefits of not tanning paired with images depicting healthy skin; and two were loss-framed messages which focused on the risks associated with tanning paired with images showing damaged skin. Participants’ intentions to tan, past tanning experiences and additional demographic information were collected and analyzed.
Results from the study indicated that loss-framed graphic messaging was most effective in lowering intentions to tan indoors compared to text only or gain-framed graphic messaging. While loss-framed messaging was the most effective in affecting intention to tan indoors, gain-framed messages did show stronger intentions to quit indoor tanning compared to text only messages.
“Given the established link between indoor tanning and skin cancer risk, the substantial public health burden of skin cancer, and the findings of this study, a public health communication approach closer to the FDA’s warning for tobacco products may be warranted,” the authors suggest.
