Rise In Popularity Of E-Cigarettes Sparks Concerns And Recommendations Reply

The recent dramatic rise in popularity of e-cigarettes threatens to reverse hard-fought progress in the war against smoking, according to a new policy statement from the American Heart Association. “E-cigarettes have caused a major shift in the tobacco-control landscape,” said the lead author of the statement, Aruni Bhatnagar, chair of cardiovascular medicine at the University of Louisville.

But the AHA did not completely reject the use of e-cigarettes as an aid to stop smoking.

If You Snus, You Lose: Study Shows Benefits of Quitting Smokeless Tobacco Reply

The adverse effects of smoking are well known and documented. The effect of smokeless tobacco is less clear. Now a study from Sweden, published in Circulationoffers evidence that quitting smokeless tobacco after a heart attack is about as beneficial as quitting smoking. The results do not support the common view that smokeless tobacco is a safe alternative to smoking.

Hypertension And Smoking Top List Of Global Risk Factors 1

Screen Shot 2012-12-13 at 2.57.27 PMWorldwide, hypertension and tobacco smoking are the single largest causes of death and disability, according to findings from the Global Burden of Disease Study 2010 (GBD 2010), the largest ever assessment and analysis of global health and disease. In an unprecedented move, the Lancet devoted an entire issue to the study, including seven separate articles and eight comments.

GBD 2010 was led by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington. In a press release, IHME director Chris Murray said, “For decision-makers, health-sector leaders, researchers, and informed citizens, the global burden of disease approach provides an opportunity to see the big picture, to compare diseases, injuries, and risk factors, and to understand in a given place, time, and age-sex group, what are the most important contributors to health loss.”

Despite significant reductions in the rate of ischemic heart disease and stroke since 1990, overall these retained their position as the #1 and #2 worldwide causes of death. Among men 15-49 years of age, CV disease was the single largest cause of death, accounting for 12.8% of all deaths. For women of the same age CV disease was the third largest cause of death, following HIV/AIDS and other non-communicable diseases, accounting for 10.7% of all deaths.

Ischemic heart disease in 2010 now ranks as the largest single cause of global years of life lost. In 1990 it had ranked fourth, behind lower respiratory infections, diarrhea, and preterm birth complications. Stroke moved from fifth place to third place.

High blood pressure emerged as the single most important risk factor for death and disability, followed by tobacco smoking. In 1990 the top two risk factors were childhood underweight (#8 in 2010) and household pollution (#4 in 2010).

The Research Agrees: Smoking Is Really Bad For You Reply

Four new studies offer powerful evidence of the dangers of smoking and the health benefits of quitting or not being exposed to secondhand smoke.

Smoking in the UK– Between 1996 amd 2001 the Million Women Study started following more than one million women aged 50 to 65 years of age. In  a report published in the Lancet, trial investigators, including renowned epidemiologist Richard Peto, found that 12-year mortality was significantly higher in women with a history of smoking compared to women who never smoked (rate ratio 2.76, CI 2.71-2.81). Smokers, the authors calculated, lose 10 years of life. The good news is that stopping smoking before the age of 40 reduces the excess mortality by 90%.

Smoking in Japan– The Life Span Study, published in BMJ, was started in 1950 and has followed more than 65,000 men and women in Hiroshima and Nagasaki, Japan. The results were consistent with the Million Women Study in the UK: the rate ratio for mortality was more than doubled for smokers compared to nonsmokers both for men (2.21, CI 1.97-2.48) and for women (2.61, CI 1.98-3.44). The investigators also reported that stopping smoking before age 35 eliminated almost all of the risk associated with smoking.

Smoke-free legislation meta-analysis– Smoking is not just a personal decision that has individual health effects. A new meta-analysis published in Circulation found that smoke-free legislation results in immediate reductions in hospital admissions or deaths for coronary events (RR .848, CI .816-.881), other heart disease (RR .610, CI .440-.847), cerebrovascular accidents (RR .840, CI .753-.936) and respiratory disease (RR .760, CI .682-.846). The authors, Crystal Tan and Stanton Glatz, also report that the biggest reductions in events were associated with the most stringent smoke-free laws.

Smoke-free legislation in Minnesota– Here’s one more study to lend support to the above meta-analysis. In a paper published in Archives of Internal Medicine Richard Hurt and colleagues analyzed data before and after the implementation of a smoke-free law in Olmsted County, Minnesota and found a significant 33% reduction in the incidence of MI from 150.8 to 100.7 per 100000 people and a trend in the reduction of sudden cardiac death by 17% from 109.1 to 92.0 per 100,000 people. In an accompanying commentary, Sara Kalkhoran and Pamela Ling write that as “the evidence base documenting the positive health outcomes” of smoke-free legislation grows, “we should prioritize the enforcement of smoke-free policies, eliminating loopholes in existing policies as well as encouraging expansion of smoke-free policies to include multiunit housing, motor vehicles, casinos, and outdoor locations. Exposure to SHS should not be a condition of employment, and all workers, including those of lower income and those in the service and hospitality industries, should have equal protection from SHS exposure.”
