Abstract

Upper-body fat has negative effects and lower-body fat has positive effects
on the supply of long-chain polyunsaturated fatty acids that are essential
for neurodevelopment. Thus, waist-hip ratio (WHR), a useful proxy for the
ratio of upper-body fat to lower-body fat, should predict cognitive ability
in women and their offspring. Moreover, because teenage mothers and their
children compete for these resources, their cognitive development should be
compromised, but less so for mothers with lower WHRs. These predictions are
supported by data from the Third National Health and Nutrition Examination
Survey. Controlling for other correlates of cognitive ability, women with
lower WHRs and their children have significantly higher cognitive test
scores, and teenage mothers with lower WHRs and their children are protected
from cognitive decrements associated with teen births. These findings
support the idea that WHR reflects the availability of neurodevelopmental
resources and thus offer a new explanation for men's preference for low WHR.
