What does dying from all causes mean?
What does dying from all causes mean?
In some studies, at the end of them, I see:
"quitting smoking reduces your chance of dying from all causes."
So if I quit smoking I'm less likely to get hit by a bus?
You're viewing a single thread.
It means the overall death rate in the sample group was decreased substantially. The number of people who survived because they didn't get lung cancer or blood clots was so large that it had a noticeable impact on the number of total survivors, even when you include death by bus. This is a useful measure for a couple of reasons. One, it accounts for the prevalence of the disease being prevented - cutting all pork from your diet prevents 100% of deaths by trichinosis, which accounts for like 0.00001% of deaths from all causes (completely made up numbers and example, without consulting any sources). Two, it could account for net change in survival, for a treatment or behavior that has both positive and negative effects - giving radiation therapy indiscriminately to everyone with any kind of lump might decrease rate of dying from breast cancer, but increase death "from all causes" because it causes more problems than it solves.
I guess an additional way it might be useful is if we don't yet have data on the exact mechanisms by which the treatment helps or what exactly its preventing - all we know is that we gave group A the treatment and not group B, and after 20 years there were a lot more people alive in group A, but we haven't yet found a pattern in which causes of death were most affected and how.
Thanks. I kind of feel like they should say dying from all diseases. What do I know. I'm not a scientist.
If your body is dealing with the effects of decades of smoking, it will be less effective at healing you from all ailments (including being hit by a bus), not just diseases.
My wife has stage 4 colon cancer. One thing people who don't know some who has had cancer don't understand is that you can have it for a long time before it becomes so obvious that you have it. So while she has been far more susceptible to diseases before we figured it out, she found out because she went into the first stage of sepsis due to a necrotic tumor in her uterus that got infected. Sepsis isn't a disease, it's condition. Any infection can cause sepsis so it isn't a symptom but something caused by the symptoms, an add on effect, if you will. If not treated in time, you die of septic shock. Again, septic shock isn't a disease but a condition brought on by a disease. So no, dying from all diseases does not cover everything that you can die from that cancer or emphysema or COPD can have an effect on. In my wife's case, had we waited 24 hours more, she would have likely died because her organs would have started failing due to acidosis. Again, not a disease, a condition. Even if they had been able to treat her in time, her cancer would have likely made their treatments less effective than as they would have been for someone without cancer.
Let me try to put it in better terms. A disease can create a condition which can have a negative effect on the body. This condition is not necessarily solely caused by that disease, so it isn't a symptom. This condition, like acidosis of the blood, can then go on to create further problems, like organ failures, which you can die of. So in this example, the cause of death is organ failure, not acidosis, not the disease. and not the cancer. Without the cancer, the disease might not have spread as fast or happened at all. And thus, quitting smoking improves your chances of not dying from all causes, not just all diseases.
I'm sorry you're going through that. Thank you for the answer.
Wounds heal poorly for smokers. People who smoke after getting a tooth extraction can get dry socket.
I know someone who ate some rancid food, and was subsequently very, very unwell because they literally couldn't taste or smell that it was off.
It affects your cardiovascular health so good luck outrunning danger.
Everything is worse if you smoke, in real time and in terms of what it does to your body's ability to heal or respond to trauma.
Don't smoke. And if you do, try and quit.
