An American study shows that people who arrive after quitting smoking may have an increased risk of developing type 2 diabetes (diabetes mellitus), indicating that health professionals should concentrate on good diet and physical activity in addition to smoking cessation. .
The study, conducted by a team from Chan School of Public Health of Harvard T.H., analyzed data on 171,150 male and female subjects for an average of 19 years.
Participants were asked to complete questionnaires every two years about their health and lifestyle, so that researchers could assess who did stopped smoking the impact of their weight gain about the risk of developing one diabetes mellitus and about the risk of death more for cardiovascular disease or others.
Scientists have discovered that, compared with smokers, those who recently stopped had an average increased risk 22% of type 2 diabetes. This risk was greatest between five and seven years after stopping smoking and then gradually decreased.
As test subjects became heavier after stopping, their risk of diabetes increased.
However, those who did not arrive did not register an increased risk and in the long term had a stopping smoking effect. advantageous about the risk of diabetes. Among people who have stopped smoking for 30 years, the risk of diabetes was comparable to that of people who had never smoked.
Stopping smoking leads to other important benefits
"We know that people who stop smoking are at high risk of diabetes and can prevent smokers from stopping", commented Qi Sun, the author of this research."But our study shows that the change in weight after stopping determines the risk of diabetes, so as long as they reduce their weight gain, their chances of diabetes do not increase and will decrease over the long term. ."
Stop smoking leads others significant benefits. The study showed that even in people who had taken more than 10 kg, the risk of premature mortality due to cardiovascular disease decreased by an average of 67% and the risk of other causes decreased by 50% after the cigarette stopped.
"Smokers should not be discouraged by potential weight gain after stopping because the risk reduction for cardiovascular disease is clear, both in the short and the long term.Hu said, also responsible for this study.
However, people who stop smoking should think about adopting one balanced diet and have physical activities to minimize weight gain to prevent the risk of diabetes and maximize the health benefits of stopping. "
