SpotlightText Messaging Found to be Effective Smoking Intervention A recent study conducted in the UK has shown that people receiving encouraging text messages as part of a smoking cessation regime experience a quit rate two times higher than those in a placebo group. The study, txt2stop, a single-blind, randomized trial, was funded by the UK Medical Research Council. It was constructed using two groups of participants, those who would receive the txt2stop smoking cessation texts, and those who only received generic texts with information and news about the study. The 5,885 participants in the control group received messages like this one: "Thanks for taking part! Without your input the study could not have gone ahead!" The 5,915 participants in txt2stop group received messages that were often motivational in nature and could be sent in real time in response to the subject's physical or emotional state. An example of this is in the event of a craving. A participant could text the word "crave" to txt2stop and would receive a message similar to this: "Cravings last less than 5 minutes on average. To help distract yourself, try sipping a drink slowly until the craving is over," according to the txt2stop study authors. This exercise can also be done by texting the word "lapse" as well. The study's methodology outlined that during the study all participants were to be texted five times a day for the first five weeks, with the following six month period featuring only three texts per week, not including texts in response to "crave" or "lapse" messages. During the six month trial period all participants were asked to self report their rates of cessation. Once the trial period was over, all study subjects had their saliva tested for actual nicotine levels in order to gauge the real cessation rate. The results showed that after six months, 10.7% of the txt2stop participants had successfully quit smoking, compared to 4.9% of the control group. According to Professor Max Parmer, director of the Medical Research Council's clinical trials unit, "This research has shown that texting could be a powerful tool to help people to walk away from cigarettes for good." While these results are similar to other successful smoking cessation techniques and interventions, they remain important for a few reasons. First, the study's authors found that the txt2stop intervention is effective in all socioeconomic groups that participated, as well as in both younger and in older smokers. Second, the txt2stop program is easy to combine with other smoking cessation methods such as medication and one-on-one counseling. Last, the study's authors point out that the txt2stop intervention is an ideal model for delivery of a tobacco cessation message on a national or international level. They point out that the technicalities involved in making necessary adjustments between cultures and languages are fairly minor. Translation and adaptation can easily be done at a low cost. This exciting study has contributed a potentially valuable new tool to the smoking cessation arsenal. The prospects for its use in North America are vast, as mobile technology is continually evolving. Txt2stop already has shown a decent success rate using simple text messages. The possibilities of more involved messages, or even a txt2stop smart phone app that could distract users during a "crave" moment, may lead to an even higher rate of quitting, especially when used in combination with other smoking cessation techniques.
Research HighlightsADHD, Learning Issues May Be Linked to Secondhand SmokeChildren exposed to secondhand smoke in their homes face a higher risk of developing attention-deficit/hyperactivity disorder, other behavioral problems and learning disorders, a new study finds. The research doesn't definitively prove that tobacco smoke can harm children's brains, and it doesn't say how much smoke is too much. However, it does add to the evidence that children may be especially vulnerable to the effects of smoke exposure. "They're in a developmental stage and their body is growing," potentially putting them at greater risk of disruptions to their brains than adults, said study co-author Hillel R. Alpert, a research scientist at Harvard School of Public Health's Center for Global Tobacco Control in Boston. It's difficult to confirm whether secondhand smoke causes children's health problems because it would be unethical to expose kids to smoke and watch what happens to them. Instead, researchers often must look backward, as they did in this study, and try to eliminate all explanations but one for a link between smoke exposure and illness. For their study, published online July 11 in the journal Pediatrics, researchers examined the results of a 2007 U.S. telephone survey of families that included 55,358 children under the age of 12. Six percent of them were exposed to secondhand smoke in the home. After adjusting their numbers to improve their validity from a statistical point of view, the researchers found that about 8 percent of the kids had learning disabilities, 6 percent had attention-deficit/hyperactivity disorder, and almost 4 percent had behavioral and conduct disorders, such as oppositional defiant disorder. Those who lived in homes with smokers were more likely to have at least two of the conditions, even after the researchers adjusted their statistics to account for such factors as income and education levels of parents. The researchers estimated that secondhand smoke may be responsible for 274,100 extra cases of the three types of disorders examined. Older children, particularly those between 9 and 11 years old, boys and poor children were most at risk of developing the disorders as a result of smoke exposure, the researchers found. Children with smoke exposure at home were also more likely to receive behavioral counseling or treatment, which greatly increases health care costs, the survey found. "Parents should consider banning smoking from their homes," Alpert said. No only are children vulnerable because of their physiology, "they're also vulnerable because they do not necessarily have the choice about being exposed to smoke or not," he added. According to the U.S. Environmental Protection Agency, secondhand smoke has been linked to increased severity of asthma in 200,000 to 1 million children and 150,000-300,000 lower respiratory tract infections in babies. Secondhand smoke is also linked to increased risk of sudden infant death syndrome. Based on the survey results, the researchers concluded that about 4.8 million U.S. children under the age of 12 live in homes with a smoker, which is slightly less than previous estimates.

Higher Cigarette Taxes Don't Faze Certain Age, Income GroupsWealthy people and adults ages 25 to 44 aren't deterred by cigarette taxes, continuing to light up despite the climbing price of a pack, a new Canadian study finds.The study focused on the long-term impact of taxing cigarettes and found that higher taxes encourage low-and middle-income earners to quit. However, price increases do not persuade wealthier smokers to quit, according to researchers from Concordia University in Montreal. In the United States, cigarettes are subjected to state and federal taxes, with New York having the highest cigarette tax of all U.S. states, at an average of $4.35 per pack, while Missouri at $0.17 per pack has the lowest state cigarette tax. "Overall, it was smokers from lower socioeconomic groups who are more price-responsive than those from higher socioeconomic groups," study researcher Mesbah Sharaf said in a statement. But the numbers of low-and middle-income smokers who kick the habit in response to higher taxes do add up. "If there is a 10 percent increase in taxes, then smoking participation will fall by about 2.3 percent," Sharaf said. After examining data from the National Population Health Survey conducted from 1998 to 1999 and 2008 to 2009, the researchers analyzed three age groups of daily smokers: ages 12 to 24; 25 to 44; and 45 to 65. The findings showed that, of the three groups, people ages 25 to 44 kept puffing away even when faced with higher cigarette taxes. The study also found that people with a postsecondary education, such as a bachelor's or associate's degree, were less likely to smoke than those who did not finish high school. "The lowest percentage of smokers can be found among women who are married, older, with high income and more education," study researcher Sunday Azagba said. The findings, which were announced this week, were detailed online May 16 in the International Journal of Environmental Research and Public Health.
Less Lighting Up in Movies Aimed at KidsThe number of films that children are likely to see that include smoking has dropped for the fifth straight year, a new report finds. Overall, there has been a nearly 72 percent drop since 2005 in smoking depictions in movies rated G, PG or PG-13 -- from 2,093 incidents of onscreen smoking to 595 in 2010. In addition, the average number of smoking incidents in youth-rated films dropped more than 66 percent -- from about 20 percent in 2005 to 6.8 percent in 2010. "This study shows that studios know how to eliminate smoking from youth-rated movies and have nothing to fear from a policy requiring them to do so," said Vince Willmore, a spokesman for the Campaign for Tobacco-Free Kids. "The Motion Picture Association of America should move quickly to adopt a policy requiring an R-rating for any movie that depicts smoking that is not in a historical setting," he said. However, the drop in onscreen smoking varied depending on the motion picture company, according to researchers led by Stanton Glantz, director of the Center for Tobacco ControlResearch and Education at the University of California, San Francisco. His team found that from 2005 to 2010, companies that had policies to reduce onscreen smoking had an average decrease in depictions of almost 96 percent, compared with about 42 percent among companies that have no such policies, according to the report. The report is published in the July 15 issue of the U.S. Centers for Disease Control and Prevention's journal, Morbidity and Mortality Weekly Report. The report is published in the July 15 issue of the U.S. Centers for Disease Control and Prevention's journal, Morbidity and Mortality Weekly Report. According to the U.S. National Cancer Institute, studies show that seeing smoking in movies is directly related to getting adolescents to start smoking. In fact, teens exposed to the most onscreen smoking are twice as likely to start smoking as teens who see little or no onscreen smoking, the new report said. That's why it's heartening that "the percentages of 2010 top-grossing movies with no tobacco incidents were the highest observed in two decades," according to the studyauthors. They contend that the drop in onscreen smoking "might have contributed to the decline in cigarette use among middle school and high school students."

Teens' Hearing Loss Linked to Secondhand SmokeSmoke gets in your ears -- if you're a teen exposed to secondhand smoke -- and is associated with hearing loss, a large study suggested. Exposed adolescents were 1.83 times more likely to experience low-frequency hearing loss (95% CI 1.08 to 3.41) than those who had no exposure, according to Anil K. Lalwani, MD, and colleagues from New York University in New York City. And the greatest risk for hearing loss -- a 2.72-fold increase (95% CI 1.46 to 5.06) -- was in those with the highest levels of exposure as determined by serum cotinine levels, Lalwani's group reported in the July Archives of Otolaryngology-Head & Neck Surgery. The list of potentially harmful outcomes associated with exposure to secondhand smoke continues to grow, from low birth weight to behavioral and cognitive problems and respiratory tract infections -- and more than half of U.S. children are exposed. In the first study to examine secondhand smoke exposure and sensorineural hearing loss in young people, the investigators analyzed cross-sectional data from the 2005-2006 National Health and Nutrition Examination Survey (NHANES). They identified 1,533 nonsmokers ages 12 to 19 who had undergone audiometric testing and whose serum cotinine levels had been measured. Low-frequency sensorineural hearing loss was defined as a pure-tone level above 15 dB for 0.5, 1, and 2 kHz, while high-frequency loss was a level above 15 dB for 3, 4, 6, and 8 kHz. Overall rates of hearing loss were:
Yet only 18.43% of the teens with these forms of hearing loss were aware of the problem. In a bivariate analysis of factors that could influence hearing loss, unilateral low-frequency loss was more prevalent among teens exposed to secondhand smoke (11.82% versus 7.53%, P=0.04). Rates of unilateral high-frequency loss also were higher among the exposed (17.09% versus 13.86%), although this difference was not significant. Other factors associated with hearing loss included a history of eczema, black race, and having been cared for in a neonatal intensive care unit. When participants were divided into quartiles by level of serum cotinine, the prevalence increased from 7.53% in nonexposed adolescents to 17.05% of those with the highest level of this marker of tobacco exposure (0.858 μg/L to 15 μg/L). The researchers noted that the link of secondhand smoke exposure with elevated thresholds ranging from 0.5 kHz to 8 kHz suggests "that the injury to the inner ear is global." In addition, the unilateral hearing loss is probably an early phase of ocular damage that is likely to progress in severity, they cautioned. The elevated thresholds at 2, 3, and 4 kHz were particularly important, according to Lalwani and colleagues. "These mid-to-high frequencies are critical for hearing in humans and are responsible for the clarity of hearing that allows us to discriminate between similar sounding words," they observed. Possible mechanisms by which secondhand smoke could result in auditory damage include effects on the vasculature of the inner ear and injury from nicotine or other components of the smoke. Hearing loss in young children has been shown to interfere with not only speech and language development, but also cognitive function, academic progress, and social interaction. But neonates and young children are routinely screened for hearing difficulties, while adolescents are not. The findings of this study suggest that teens who are exposed to secondhand smoke should have their hearing tested, and parents and caretakers should be made aware of the auditory hazards of their smoking. Limitations of the study include its use of cross-sectional data which doesn't allow assignment of causation, lack of information on duration and sources of secondhand smoke exposure -- including prenatal exposure -- and absence of data on other factors such as exposure to loud noises. The researchers also were unable to rule out the possibility that some of the participants had conductive, rather than sensorineural, hearing loss. They concluded, "Future studies need to investigate the adverse consequences of this early hearing loss on social development, academic performance, behavioral and cognitive function, and public health costs." The study was supported by the Zausmer Foundation and the National Institutes of Health
Return to Smoking After Heart Attack Ups Death RiskAfter a heart attack, quitting smoking may offer a patient more benefits than any medication, but Italian researchers say the flipside is that resuming smoking after leaving the hospital can raise the same patient's risk of dying as much as five-fold. On average, people who started smoking again after being hospitalized for acute coronary syndrome (ACS) -- crushing chest pain that often signals a heart attack -- were more than three times as likely to die within a year as people who successfully quit in a study led by Dr. Furio Colivicchi of San Filippo Neri Hospital in Rome. "Relapse is a major risk factor for long term survival," said Dr. David Katz, associate professor of internal medicine at University of Iowa Carver College of Medicine in Iowa City. Quitting smoking has a similar lifesaving effect for ACS patients as taking recommended drugs to lower blood pressure or cholesterol, added Katz, who was not involved in the new study. To gauge the effects of resuming smoking after a heart "event," and to see how many people are likely to relapse, Colivicchi and his colleagues tracked 1294 patients who reported being regular smokers before they were hospitalized with ACS. All the participants had ceased smoking while in the hospital and declared themselves motivated to continue abstaining once they were released. Patients received a few brief smoking-cessation counseling sessions while in the hospital, but no further counseling, nicotine replacement or other smoking-cessation help was provided after they left the hospital. The researchers interviewed patients about their smoking status at one, six, and 12 months after their release from the hospital and found that a total of 813 (63 percent) had relapsed by the end of the first year. About half had begun smoking again within 20 days of leaving the hospital. Within a year, 97 patients died, with 81 of those deaths attributed to cardiovascular causes, according to findings published in the American Journal of Cardiology. After adjusting for patient ages and other variables, the researchers found that resuming smoking raised a person's risk of death three-fold compared to patients who didn't relapse. The earlier a patient fell off the wagon, the more likely he or she was to die within a year -- those who resumed smoking within 10 days of leaving the hospital were five times as likely to die as those who continued to abstain. Very few patients relapsed after being smoke-free for six months. "If you manage to stay off cigarettes for six months, you probably have the addiction beat," said Dr. Nancy Rigotti, director of the Tobacco Research and Treatment Unit at Massachusetts General Hospital in Boston, who was not involved in the study. Colivicchi's group did not measure how often the patients smoked -- an important predictor of relapse and early death, Katz noted. Nonetheless, the results indicate a need to improve the way doctors help patients quit smoking, said Rigotti. "People don't take treating tobacco use seriously in the medical setting," and recommended treatments have not made their way into practice, she said. Colivicchi agreed. A successful program to help patients quit should take "a comprehensive long-term approach, including individual counseling, post-discharge support and pharmacological treatment," he told Reuters Health in an email. A recent study from Harvard Medical School suggested that a comprehensive anti-smoking counseling program for heart attack patients could save thousands of lives at a relatively low cost. These findings, along with the results of the Italian study, said Rigotti, suggest that hospitals and insurers should work together to implement comprehensive anti-smoking programs to continue to help patients after they leave the hospital.
