Do Oral Contraceptives Help Women Live Longer?

Rate: 8 Flag

A recent study conducted at the University of Aberdeen in Scotland has concluded that women using oral contraceptives might have health and longevity advantages over those who don't.

'The Pill,' long associated with health risks including increased risk of blood clots in younger women, has not previously been associated with longevity.  As a means to suppress ovulation by artificial hormone stimulation, oral contraceptives came into widespread use in the 1960's, primarily to prevent unwanted pregnancy.  Oral contraceptives have been prescribed by physicians for purposes other than contraception, however.

The Aberdeen study, funded by the Royal College of GPs,  found women taking oral contraceptives were less likely to die by 12 per cent overall than women not taking the Pill, and found greater benefits in various diseases like cancer and heart disease.  The risk of death from bowel cancer is decreased 38 per cent in women taking birth control pills.  Risk of death from uterine and ovarian cancers is also significantly diminished.

The study followed over 46,000 women from 1968 for a period of almost forty years.

Benefits seemed to increase as a woman aged.  Women in younger age groups, under thirty, and those thirty to forty, demonstrated increased risk of death from taking oral contraceptives, but the researchers felt those risks were outweighed by the benefits in later life.  The health risks of taking the Pill disappeared after ten years.

The study concluded, "Although the proportion of increases or decreases in mortality directly attributable to oral contraception cannot be determined, these figures indicate that, at least in this relatively healthy UK cohort, oral contraception is not significantly associated with a major public health problem. The level of reduction in mortality seen in different parts of the world will depend on factors such as levels of oral contraception usage, duration of use, age at stopping, and the prevalence of disease."

The study, led by Dr. Philip C. Hannaford, was published in the March 11 edition of the British Medical Journal.

My first thought when I read the headline was Yes, they probably do if only because women will carry and birth fewer children in their lifetime while enjoying a healthy sex life - both factors that could contribute to longevity. The results you cite are very interesting though. It would be great if women benefited in unexpected ways from their contraception.
When I was in my 20's taking the pill, I was horrified at the idea of the dreaded blood clots and other side effects. It is difficult for me to imagine them helping us live longer. Interested in finding out more about this as now, my daughter is 20. Valuable information. xxa
it's easy to get caught up in misleading journalism like this seeing only what we want to see. i strongly suggest to read the link given by this poster below, from which she partially quotes and to get a better idea for yourselves about the subject. below are two excerpts from the source she uses.

"A recent publication from the study using incident cancer data has suggested that ever users of oral contraceptives may have a reduced overall risk of cancer.5 Whether this translates into an important mortality benefit, and if so how it relates to other causes of death, is unknown."


"Although the proportion of increases or decreases in mortality directly attributable to oral contraception cannot be determined, these figures indicate that, at least in this relatively healthy UK cohort, oral contraception is not significantly associated with a major public health problem. The level of reduction in mortality seen in different parts of the world will depend on factors such as levels of oral contraception usage, duration of use, age at stopping, and the prevalence of disease."
This is certainly intriguing, although I imagine there will need to be plenty more research before a clear link can be established.

As with most medications, there are benefits and risks. Physicians have felt that the risks outweigh the risks for many decades now. Controversy over risk of breast cancer has been pretty much resolved in favor of no effect. There are benefits in terms of less blood loss with menses (which may be significant for many women), and decreased risk of endometrial (uterine) cancer. Not to forget that the original investigation of oral contraceptives caused several deaths in the Puerto Rican woman where it was first tested. These days, the "pill" has far less hormone content than early pills did. The risk/benefit lines cross and tend towards unacceptable risk of blood clot for women over age 35 who smoke or have high blood pressure. Other than political objections, many reproductive health professionals believe that the pill should be available over the counter because of its safety profile.
Kathy, very intriguing information. A few additional medical points: the doses of hormones in today's oral contraceptives are just a fraction of the ones initially introduced in the 60s, and as a result are much safer than they were. Risks of blood clots are greatly increased by smoking cigarettes, another reason not to smoke (as if we needed another reason). The risk of medical problems are much higher in an unwanted pregnancy than from taking oral contraceptives. I haven't ready this study yet but plan to; it has huge importance worldwide. Thanks for presenting this.
Hope it's true, but one of the problems with these studies seems to be that a conflicting one comes out the following year, and nobody knows what's what.

Important information, important post. I take the Pill for granted, but when I think about it I owe it my life in many ways already. Thank you.
I started on the Pill when I was 11. It wasn't until last Summer (I'm now 33) that the heavy, painful periods with associated vomiting, bowel-upset and exhaustion were collectively diagnosed as endometriosis.

The Pill (and the new-fangled other methods of delivering synthesised progesterone; coil, implant, injection etc) have had another effect upon me aside from those considered here and in the (wonderfully thoughtful) comment: I am no longer in agony for 6 days out of every 28. And when you put it like that; almost a quarter of my life given up to pain, discomfort, inability to eat or digest properly and the constant stream of drugs required to temper these effects... well, it strikes me that -of course- my health is better thus I'll live longer.

There is also an argument to be made for the reduction of stress generally in women, not just in those who take the combi-pill (or straight up prostin) to control various unpleasant symptoms; we already know that Stress Is Bad, and I remain mystified that the monthly stress that many women go through (while balancing marriages, careers, children, a home, life in general) are so easily and frequently overlooked.

The Pill is, simply put, a life-saver to many of us already and more information such as this article needs to be made readily available to GP's, sexual wellness clinics and adolescent girls who are currently taught to tremble at the thought of taking the Pill AND flying in an aeroplane at the same time.

It's not longer only about contraception; it hasn't been for a long time. This article serves to highlight what many, many women have been saying for years: without it we'd be utterly lost.
I don't believe it for a second. I'm sure another study will come out in a year completely the opposite of this one. Or we'll find out they fudged the numbers. Screwing around with womens hormones by taking synthetic hormones for years and years can't be good for you, no matter what the latest study shows. Junk science, blech.
Nowadays I look at any medical study with a grain of salt, because it is likely another will follow shortly to disprove or point to the omissions in it. Thank you for the links; I'll read when I have more time.
I have to agree with seafarer and Deborah here - the pill has been around for about 50 years with relatively widespread use, but more recent methods of birth control delivery have not been around long enough to make any conclusions. I think any long-term use of a hormone should not be taken lightly, and far too few studies are being conducted on long term effects of exogenous hormones. Note that this study is from the U.K. - not surprising. The US puts far too few resources into womens' health research - a real shame. We know an awful lot about Viagra and the prostate after all...
