Interesting but really?

Keeping fit protects against getting cancer and dying from it, the largest study of its kind has concluded.

The fittest people more than halved their risk of bowel or lung cancer and cut their risk of dying of it, researchers in the US found.

So, smoking but keeping fit as well leaves you with no increased risk of lung cancer?

Or they already defining being fit as not smoking?

  1. Since I’m a very fit 70 years old, I’d like to believe this.

    But there is so much junk science in epidemiology that I can’t.

  2. It’s like an old funding scheme I was involved with. Poor areas have more traffic accidents, so we’ll weight the amount of money both by how poor an area is and how many traffic accidents there are.

  3. I suppose cancer rates might appear to be going up simply because there have been advances at detecting it earlier. Does anyone know a good source on this matter?

  4. Obesity increases the risk of cancer as well as diabetes.
    Keeping fit reduces obesity. [It also strengthens, or slows down the weakening of heart muscles]
    Have they adjusted the results for levels of obesity?

  5. Can’t be troubled to look it up, but I’m sure many studies have said that the slightly overweight tend to live the longest.

    Since I can’t square “Keeping fit protects against getting cancer and dying from it” and the overweight live longer, I’d say this study is piecewise cubic shit.

  6. Dearime,

    The probability of death is 1, which is the sum of all the probabilities listed by cause. When you reduce one cause, the others increase to keep the sum at 1. Small variations in percentages are likely to be statistical blips, systematic change implies one cause is being eliminated. The causes unlikely to be eliminated totally are those due to wearing out or malfunction.

    The study includes ‘and dying from it’ where early detection doesn’t help, I guess. Early detection might help with ‘and not dying from it quickly’.

    Since I can’t square “Keeping fit protects against getting cancer and dying from it” and the overweight live longer, I’d say this study is piecewise cubic shit.

    As we’ve discussed before, its the definition of overweight that is bollocks.

  8. Good point, BiND. If it makes you live longer, it should be ‘ideal,’ not ‘over.’
