Body fat percentages and Body Mass Index (BMI) values in Black and White people in New York
A study comparing New York’s white and black persons.
|BMI||fat %||BMI||fat %|
Men had similar BMI and body fat percentage, and although black women had higher values than white women, the ratio of body fat to Body Mass Index is extremely close. This is illustrated in the chart below, where black and white women’s data of body fat percentage and BMI is completely overlapping. (Also true for men).
This article has some data about leg length, saying that Black’s have longer legs than Whites. This theoretically affects BMI, but it didn’t seem to matter in this study.
Regarding Elderly people, this article says that, for people with BMI of 23, the body fat percentage increases 1.0 to 1.1 percent (men) or 0.7 to 1.0 percent (women) per decade.
Regarding Gender differences, this article says that, for 20-year olds with a BMI of 23, the men would have 13.3% body fat, and women would have 26.0%. For 80-year olds, men’s body fat would be 23.9% and women’s body fat percentage would be 32.6%. In other words, it seems natural for young women to have 12.7% greater body fat than men. (That seems a little high).
This article suggests some formulas to predict body fat percentage, based on BMI, Age, Gender and Race.
