" Today's Topic: Walk Till Your Sugar Drops Traditional advice concerning physical activity is that you need vigorous activity for half your waking hours. A report in the October 20, 1999 edition of the Journal of the American Medical Association (JAMA) shows that walking is effective in reducing the development of diabetes in middle-aged women and cut the rate by about half. Over 1,400 cases of type 2 diabetes were diagnosed over eight years in 70,000 female nurses. < http://jama.ama-assn.org/cgi/content/abstract/282/15/1433 > The data in this study are statistically adjusted for all known risks such as age, smoking, alcohol use, body mass index (BMI), etc. Even taking into account differences in BMI, walking still reduced the number of women with diabetes. The more time per week spent walking and the faster the walking pace, the greater the benefit. HERE'S WHAT YOU NEED TO KNOW: Although about half the protective effect of walking seems related to lower BMI, there is an independent protective effect at any given weight. As the population in the U.S. continues to get heavier, we can expect the number of diabetics to increase. Moderate to brisk walking is one means of countering this unhealthy trend. While we are enthusiastic about these results, it must be remembered that observational studies like this, inherently, cannot prove cause and effect.
