Women smokers who quit by 30 'evade earlier death risks'
Women who give up smoking by the age of 30 will almost completely avoid the risks of dying early from tobacco-related diseases, according to a study of more than a million women in the UK.
The results, published in the Lancet, showed lifelong smokers died a decade earlier than those who never started.
But those who stopped by 30 lost, on average, a month of life and if they stopped by 40 they died a year younger.
Health experts said this was not a licence for the young to smoke.
The study followed the first generation of women to start smoking during the 1950s and 60s. As women started smoking on a large scale much later than men, the impact of a lifetime of cigarettes has only just been analysed for women.
"What we've shown is that if women smoke like men, they die like men," said lead researcher Prof Sir Richard Peto, from Oxford University.
He told the BBC: "More than half of women who smoke and keep on smoking will get killed by tobacco.
"Stopping works, amazingly well actually. Smoking kills, stopping works and the earlier you stop the better."
Professor Peto added the crucial(решающий) risk factor was "time" spent smoking, rather than amount.
"If you smoke 10 cigarettes a day for 40 years it's a lot more dangerous than smoking 20 cigarettes a day for 20 years," he said.
"Even if you smoke a few cigarettes a day then you're twice as likely to die at middle age."
He added it was hard to measure the risk of "social smoking" a few times a week.
Early death The records from 1.2 million women showed that even those who smoked fewer than 10 cigarettes a day were more likely to die sooner.
Sir Richard said that it was exactly the same picture as for men.
The British Lung Foundation said the prospects for long-term health were much better if people stopped smoking before they were 30, but cautioned that this was not a licence to smoke "as much as you want in your 20s".
Its chief executive, Dr Penny Woods, said: "Stopping smoking can also be difficult to do - an estimated(приблизительно) 70% of current smokers say they want to quit, so you shouldn't start and just assume you'll be able to quit smoking whenever you want to.
"The best thing for your health is to avoid smoking at all."
Prof Robert West, from the health behaviour research unit at University College London, said it was important to remember that smoking had more effects on the body than leading to an early death, such as ageing the skin.
"Around your mid-20s your lung function peaks and then declines. For most people that's fine - by the time you're into your 60s and 70s it's still good enough. But if you've smoked, and then stopped there isirreversible(необратимый) damage, which combined with age-related decline can significantly affect their quality of life.
"Obviously there is an issue around smoking if they want to get pregnant because it affects fertility and then there are the dangers of smoking during and after pregnancy."
The chartered health psychologist, Dr Lisa McNally, who specialises in NHS stop smoking services, also emphasised(подчеркнула) other factors.
Speaking to BBC News, she said: "There's the danger isn't there that people could almost take permission to continue to smoke to 30 or even to 40, but actually in my experience younger women quit smoking for other reasons other than life expectancy.
"They're more concerned about the cosmetic effects."
The Department of Health has announced that more than 268,000 people registered to take part in its "Stoptober" campaign - the UK's first ever mass event to stop smoking.
Health minister Anna Soubry said the £5.7m campaign had "exceeded expectations", adding that smokers were "five times more likely to give up for good after 28 days".
What age should smokers give up smoking by? When was the first generation of women who start smoking?
This article is little hope for under thirty smokers. They still can give up smoking and live long life. I like articles that make you think. It's one of these ones.
I think that smoking is a bad habit. I smoke but i know that it is really harmful. So guys never start smoking. It is really hard to give up this awful habit
In my opinion,it is one of the biggest problems in the world.Many people smoke every day and it is a pity.Firstly,it is harmful to health,but many people do not realize it.Moreover,smokers harm people who do not smoke.I think people should give up this habit.
It is known that smoking is a big harm!! People should take care of their health. But we harm ourself. It is wrong!!!As for me, smoking must be forbiden."The best thing for your health is to avoid smoking at all." -i agree with this phrase.
In my opinion,smoking is one of the most harmful habits.It is a very nasty habit.I don't understand why people smoke!As for me,I have never tried to smoke and I am proud of it!!!
