US researchers found that even after the age of 80, smoking increased a person's risk of developing AMD, age-related macular degeneration, the leading cause of blindness among Americans aged 65 and over, suggesting it is never too late to give up the habit. The study was the work of lead author Dr Anne Coleman, professor of ophthalmology at the Jules Stein Eye Institute at University of California, Los Angeles (UCLA), and colleagues, and is published in the January issue of the American Journal of Ophthalmology. AMD causes a darkening and/or blurring of central vision, and prevents you from being able to read, drive and recognize people you know. It is a progressive degeneration of the macula, the centre of the retina, the part of the membrane inside the back of the eye that allows us to see fine details.
As the US population becomes increasingly obese while smoking rates continue to decline, obesity has become an equal, if not greater, contributor to the burden of disease and shortening of healthy life in comparison to smoking. In an article published in the February 2010 issue of the American Journal of Preventive Medicine, researchers from Columbia University and The City College of New York calculate that the Quality-Adjusted Life Years (QALYs) lost due to obesity is now equal to, if not greater than, those lost due to smoking, both modifiable risk factors. QALYs use preference-based measurements of Health-Related Quality of Life (HRQOL) which allow a person to state a relative preference for a given health outcome.
Cigarette smoking is a well-known risk factor for type 2 diabetes, but new research from Johns Hopkins suggests that quitting the habit may actually raise diabetes risk in the short term. The researchers suspect the elevated diabetes risk is related to the extra pounds people typically put on after renouncing cigarettes and caution that no one should use the study's results as an excuse to keep smoking, which is also a risk factor for lung disease, heart disease, strokes and many types of cancer. "The message is: Don't even start to smoke, " says study leader Hsin-Chieh "Jessica" Yeh, Ph.D., an assistant professor of general internal medicine and epidemiology at the Johns Hopkins University School of Medicine.
New research suggests that quitting smoking may raise the risk of developing type 2 diabetes in the short term, and as ex-smokers log more years without touching cigarettes, that risk gradually comes down to that of a never-smoker; the researchers suspect weight gain is the main reason and warn quitters to watch their weight. These are the findings of a study by researchers from the Johns Hopkins University School of Medicine in Baltimore, Maryland, the University of North Carolina at Chapel Hill, both in the US, and the Federal University of Rio Grande do Sul in Porto Alegre, Brazil. Cigarette smoking is already a well-established risk factor for type 2 diabetes, but when smokers quit, they typically put on extra pounds.
A US study this week reported that giving up smoking increases the risk of developing Type 2 diabetes. The researchers looked at 10, 892 middle-aged adults who were followed for up to 17 years and found the risk of developing Type 2 diabetes was highest in the first three years after giving up smoking. 70 per cent increased risk The study found quitters had a 70 per cent increased risk of developing Type 2 diabetes in the first six years without cigarettes compared with non-smokers, due to them tending to put on weight. "If you smoke, give it up. That's the right thing to do. But people have to also watch their weight, " said researcher, Dr Jessica Yeh. Not an excuse not to give up smoking However, stressing the research should not be used as an excuse not to give up smoking Natasha Marsland, Care Advisor Diabetes UK, said: "The health benefits of giving up smoking far outweigh the risk of developing Type 2 diabetes from modest, short-term weight gain.
Today the U.S. District Court for the District of Columbia issued a decision granting leading global electronic cigarette brand NJOY's motion for preliminary injunction seeking to prevent FDA from detaining or refusing admission into the U.S. of its electronic cigarette products, a result that should help ensure that committed smokers have continued access to this alternative smoking product. "This is a very important day for our company, which has been on the front lines of the political, legal, consumer and scientific conversations about electronic cigarettes since we introduced the category to North America quite a few years ago now, " said CEO Jack Leadbeater.
New research on deaths from cancer in Europe concludes that the key priority for continuing to reduce mortality is cutting tobacco smoking. The study shows that, while deaths for men from lung cancer in the EU have declined overall, by 17 % from 1995 to 2004, they rose by 27% for women over the same period. It also reveals other significant differences in the mortality between different EU countries and genders, and a steady decline in cancer deaths overall between the early 1990s and 2004. The gender 'splits' reflect how the spread of cigarette smoking among men and women across Europe has changed in the past. For example, the lowest death rates for women in the early 2000s were in Spain, Greece and Portugal, the highest being in Denmark, Hungary and Scotland.
The Honourable Leona Aglukkaq, Minister of Health, announced today an important investment that will help encourage Canadians to quit smoking and lead healthier lives. Health Canada is providing just over $2.4 million dollars in funding to the Ottawa Heart Institute Research Corporation for a project that will assist hospital out-patients with smoking cessation. "The Government of Canada remains committed to protecting all Canadians from the proven health hazards associated with tobacco use, " said Minister Aglukkaq. "Today's funding is a step towards ensuring we get Canadians the help they need to quit smoking." Funding from today's announcement will go towards a project entitled "Extending Tobacco Treatment Excellence: a National Dissemination of Systems".
Adverse events in childhood have been linked to an increase in the likelihood of developing lung cancer in later life. Researchers writing in the open access journal BMC Public Health describe how the link is partly explained by raised rates of cigarette smoking in victims of childhood trauma, but note that other factors may also be to blame. David Brown and Robert Anda, from the Centers for Disease Control and Prevention, Atlanta, USA, worked with a team of researchers to study the effects of abuse (emotional, physical, sexual), witnessing domestic violence, parental separation, or growing up in a household where people were mentally ill, substance abusers, or sent to prison.
Addressing tobacco use without judging the user appears to help people quit, especially if a primary care physician uses a form of supportive counseling called "motivational interviewing, " according to a new review of studies. The review included data from 14 studies published between 1997 and 2008, with more than 10, 000 smokers involved. "While motivational interviewing has been widely used to help people stop smoking and is recommended in many international anti-smoking guidelines, it had not yet been substantiated by evidence, " said lead investigator Douglas Lai, a family medicine specialist in Hong Kong. "This is the first rigorous review of the best evidence available and the result is encouraging.
