Studies Show Black Women Are Healthier at a Higher Weight Than White Women

Studies reveal that African American women can weigh significantly more than White women and still be healthy. By examining two standards of measurement — BMI (body mass index) and WC (waist circumference) — researchers found that while White women with a BMI of 30 or more and a WC of 36 inches or more were at greater risk for diabetes, high blood pressure and high cholesterol, Black women with those same numbers were considered medically healthy. African American women's risk factors did not increase until they reached a BMI of 33 or more and a WC of 38 inches or more.

Typically, health experts consider adults with a BMI of 25-29.9 to be overweight and those with a BMI of 30 or greater to be obese.

Peter Katzmarzyk's Studies

The study, published in the January 6, 2011 research journal Obesity and authored by Peter Katzmarzyk and others at the Pennington Biomedical Research Center in Baton Rouge, Louisiana, only examined White and African American women. No similar racial difference between Black men and White men were studied.

Katmzarzyk theorizes that the weight gap between White and Black women may have to do with how body fat is distributed differently throughout the body. What many call "belly fat" is primarily recognized as being a significantly greater health risk than fat in the hips and thighs.

Dr. Samuel Dagogo-Jack's Findings

Katzmarzyk's findings echo a 2009 study by Dr. Samuel Dagogo-Jack of the University of Tennessee Health Science Center in Memphis. Funded by the National Institutes of Health and the American Diabetes Association, Dagogo-Jack's research revealed that Whites had more body fat than Black people, which led him to theorize that muscle mass may be higher in African Americans.

Existing BMI and WC guidelines are derived from studies of predominantly White and European populations and do not take into account physiological differences due to ethnicity and race. Because of this, Dagogo-Jack believes that his findings "argue for a review of the existing cutoffs for healthy BMI and waist circumference among African Americans."
