Quit Smoking Now And Live 10 Years Longer, Ladies

Smoking may kill as many as a billion people worldwide this century. Now, a new study says that if women quit smoking before the age of 30 they could almost completely reverse the impact of smoking, while those aged forty could stand to add at least ten years to their life.

It may surprise you to learn that, in both the US and the UK, smoking ranks higher than obesity as the leading cause of preventable deaths.

This fact has spurred UK researchers, funded by Cancer Research UK, the British Heart Foundation and the Medical Research Council, into conducting one of the largest studies ever undertaken into the effects of smoking and, crucially, the benefits of quitting.

To do this a team of researchers, led by professor Richard Peto of the University of Oxford, recruited 1.3 million female participants aged between 50 to 65. This age group was important for one vital reason: they were the first generation who smoked in a sustained way through to the modern day and in a way comparable to today’s smoking habits.

In a review beginning 1996 and lasting to 2001, the scientists set out to track the lives of the 1.2 million women who were viable for the study to see what prolonged smoking did to their health and also whether the benefits of quitting smoking would be as pronounced as had been hoped.

The study, published in the Lancet, contained some eye-opening, and encouraging, findings.

Of the 1.2 million women in the sample, 20 percent were smokers, 28 percent had quit and 52 percent had never smoked.

It is important to note that 66,000 of those in the study died by 2011. Due to the United Kingdom’s national health service, each woman’s medical history was recorded as well as each participant’s cause of death, meaning that the data could also be incorporated into the study’s findings.

The researchers were able to show that those women who had smoked cigarettes throughout their adult lives were three times more likely to have died than non-smokers.

Furthermore, those who smoked throughout their adult lives were overwhelmingly more likely to suffer and then die of lung cancer, heart disease and stroke. It is important to note that even those who considered themselves light smokers, smoking less than ten cigarettes a day, were twice as likely to die early when compared to non-smokers.

Quitting before middle age, however, was shown to dramatically reduce that risk.

Women who stopped before 30 years of age were shown to have only a very small (5 percent) increased risk of death compared to non-smokers. Women who quit before they were fifty had a 56 percent increased risk of death compared with non-smokers. However, this group still showed a 72 percent decrease in mortality rates when compared to those rates associated with smoking.

The impact of quitting observed in the study was made stark in the study’s conclusion:

Among UK women, two-thirds of all deaths of smokers in their 50s, 60s, and 70s are caused by smoking; smokers lose at least 10 years of lifespan. Although the hazards of smoking until age 40 years and then stopping are substantial, the hazards of continuing are ten times greater. Stopping before age 40 years (and preferably well before age 40 years) avoids more than 90% of the excess mortality caused by continuing smoking; stopping before age 30 years avoids more than 97% of it.

Overall, those who quit smoking could stand to add ten years or more to their lives than those who would continue to smoke throughout their adult life.

What to take from this study, then?

This type of study cannot definitively prove that smoking, or quitting smoking, caused the health outcomes that were observed. While the scientists were careful to control as much as possible for other factors that might have impacted participants’ health, that kind of a conclusion would be overstating the findings.

However, given that the link between smoking and a number of diseases has already been established, and that an increased mortality rate among smokers is already well evidenced, this study apparently reinforces what we already know about smoking-related risks.

The study also points out that quitting smoking really could add years to your life, and while having never started at all would have been preferable, it really isn’t too late to quit and have a meaningful impact not only on the amount of years you will live but, and importantly, the quality of life you will also enjoy in your later years.

How much does someone have to know before they quit?

I stopped smoking at age 37 after being hospitalized three times for asthma. I'm 72 now but on a number of medications I wish I did not have to take due to COPD.

I never quit, I just said I was not going to smoke again until I could smoke without choking. That has never happened.

My mum was a heavy smoker she died when she was 84 my dad was a smoker and he died when he was 80. A friend of mine has a 93 year old grandma that smokes and according to him is still very fit. It doesn't affect everyone in the same way. As for stinking the place out unwashed human race is just as bad. (By the way I changed 2 years ago to E-Cigs)
