NIH Study Finds That Coffee Drinkers Have Lower Risk of Death

parallel_prankster writes "Older adults who drank coffee — caffeinated or decaffeinated — had a lower risk of death [full paper is paywalled, at the New England Journal of Medicine] overall than others who did not drink coffee, according to a study by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, and AARP. Coffee drinkers were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the association was not seen for cancer. These results from a large study of older adults were observed after adjustment for the effects of other risk factors on mortality, such as smoking and alcohol consumption. They also found that the association between coffee and reduction in risk of death increased with the amount of coffee consumed. Relative to men and women who did not drink coffee, those who consumed three or more cups of coffee per day had approximately a 10 percent lower risk of death. Researchers caution, however, that they can't be sure whether these associations mean that drinking coffee actually makes people live longer."

      Okay, I'm going to make a computer and car analogy.

      Suppose that on every single story that mentioned RAM in any context, there were guaranteed to be a hundred comments along the lines of "Isn't the Ram a pickup truck?" Some of these comments would be meant as in-jokes, but most would be absolutely serious. The people making the comments (a self-selected group of intelligent, technically minded people who are, supposedly, interested in the world around them) would absolutely refuse to understand, no matter how many times it was explained to them, that the word "ram" has multiple specific meanings, and that only one of those meanings is relevant to the conversation at hand.

      Wouldn't you get just a little tired of this?

      The reason why these jokes keep coming up is because "risk of death" is a ridiculous phrase if not explicitly qualified. So, for slightly different reasons, is "mortality risk."

      If you want the canonical term that's used in a statistical or medical context, just say "mortality". We'll all understand perfectly what you mean, and there will be no snickering. You don't say "mortality risk" because that would be redundant. It makes you look like you don't know what you're talking about. (Of course, if you want to create that impression, you're on the right track.)

      Another conventional term is "death rate". Both "mortality" and "death rate" refer to the relative frequency of deaths in a given population under given conditions.

    This is probably because people with bad hearts, etc., do not drink coffee, hence only people who are healthier drink coffee when they are old. Isn't it amazing that they would have a reduced death rate. Imagine what the relative death rate would be for old people who skydive, compared to those who don't?

      These results from a large study of older adults were observed after adjustment for the effects of other risk factors on mortality, such as smoking and alcohol consumption.

      So your explanation would be that people growing old and sick tend to give up coffee, but keep smoking and drinking alcohol? I guess it's possible, but I it's not obvious to me why that would be.

    Even though a larger proportion of coffee drinkers may engage in those activities (I'm not saying they do, but let's grant it, for the sake of argument), if you control for the different variables, you can still draw correlations out of the data. For instance, a coffee drinker who also smokes may, on average, live longer than someone who smokes but doesn't drink coffee as well. Likewise for red meat, less exercise, etc.. They're not suggesting that coffee drinking cancels out the effects of all those other things. They're merely suggesting it may provide some benefits over similar people not drinking coffee.

    You've alleged that their controls are terrible. Please elaborate on how, exactly, since they explicitly mentioned controlling for smoking in the article, which was one of your points.

    There was an interesting article a year or so ago that showed a correlation between coffee drinking and bowl movements vs water drinking. I will try to find it for citation, but the gist of it was: Due to the diuretic properties of coffee, the coffee drinkers had more regular bowl movements than those who drank water which meant that toxins spent less time in the intestines thus creating a lower likelihood of some intestinal diseases.

    As the text also notes:

    "The mechanism by which coffee protects against risk of death — if indeed the finding reflects a causal relationship — is not clear, because coffee contains more than 1,000 compounds that might potentially affect health," said Freedman.

    Coffee is known to be rich in antioxidants, so that could be one sporadic blind guess. But yeah.
