Not many studies have been conducted on exercise and type 2 diabetes prevention in black women. But a recent publication in the American Journal of Epidemiology shows that several brisk walks per week can help to lower black women's type 2 diabetes risk.
Julie Palmer of Boston University and her colleagues reviewed data from the Black Women's Health Study which is currently following 45,000 black women between 1995 to 2005.
Women who reported walking at least five hours per week as part of their healthy lifestyle were one-third less likely to develop type 2 diabetes than non-walkers. Even with accounting for age, income, diet – even obesity – the chances of being diagnosed w/ the disease were also significantly lower among women routinely took brisk walks.
"This is important," notes Palmer, "because it suggests a way to reduce diabetes risk even among the women who are at highest risk of the disease."
