Prostate cancer can be indolent, not posing a risk to life — or aggressive, leading to an increased risk of death. A new analysis from the large EPIC study suggests that increases in BMI and waist circumference are associated with an increased risk of the aggressive form, and thus to an increased mortality risk.
waist circumference
The claim that artificial sweeteners might contribute to obesity is one we have seen many times in the past. The newest study on the subject is a research article just published in the Journal of the American Geriatrics Society which evaluated the possibility of a relationship between the consumption of diet soda and increasing waist circumference (WC) in older Americans (i.e., over 65 years old).
The good news about obesity is that recent trends suggest that its rate of increase in Americans has stabilized. The bad news is that many of us are already overweight or obese, and a significant part of the problem, as suggested by a recent study in The American Journal of Medicine, is a widespread decrease in physical activity.
