Posted in Longevity and Age Management, Cancer, Headache, Women's Health on Mon July 13, 2009 Researchers at the Fred Hutchinson Cancer Research Center conducted a follow-up study to their original research - a first-of-its-kind study that linked migraines with breast cancer risk reduction. The results of the second study confirmed their original findings, showing that there was a 26 percent reduced risk of breast cancer in women who had been clinically diagnosed with migraines. And regardless of a woman's menopausal status, the age she was diagnosed with migraines, the use of prescription migraine medication and whether she avoided such migraine triggers as alcohol consumption, they found that the risk reduction "remained statistically" similar. |

Posted in Longevity and Age Management, Longevity, Weight and Obesity on Mon July 13, 2009 For a period of 12 years, Japanese researchers studied 50,000 people in Northern Japan between the ages of 40 and 79. They looked at each participant's build, body-mass history and the number of years they lived beyond 40. The investigators found that those men with an average body mass index (BMI) in the normal range lived an average of 79.74 years, while those who were clinically obese lived an average of 81.64 years. Women with a normal BMI at age 40 lived to an average age of 87.97 years, while overweight women lived slightly longer - to an average age of 88.05. |
