Shapely women have smart kids

NewScientist reports:
Curvier women may have smart children because hip fat contains polyunsaturated fatty acids critical for the development of the fetus's brain.

Using data from the US 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.
The study authors claimed that they accounted for other factors, but I don't believe it. Men prefer women with small waist-hip ratios. So do women. So all they really found was that female success in one area is correlated with success in another area. Maybe these women are smarter or healthier, or marry smarter husbands, or have more money, or less likely to be drug addicts, or a lot of other things.
