waist to hip ratio

I found this really cool study in the web about the waist to hip ratio and the intelegince in a fetus and it said that the study is still being reviewed, there is a moderate correlation between WHR and intelligence of offspring. Using data from the U.S. National Center for Health Statistics, William Lassek at the University of Pittsburgh in Pennsylvania and Steven Gaulin of the University of California, Santa Barbara, found a child's performance in cognition tests was linked to their mother's waist-hip ratio, a proxy for how much fat she stores on her hips.
Children whose mothers had wide hips and a low waist-hip ratio scored highest, leading Lassek and Gaulin to suggest that fetuses benefit from hip fat that contains polyunsaturated fatty acids critical for the development of the fetus's brain I found this very interesting and thought it was a great thing to talk about
