A new study suggests that the link between cognitive ability and body mass index (BMI) may be biased by shared family factors, rather than being causal. Researchers used data on 12,250 siblings from 5,602 households followed from adolescence to age 62 as part of four separate United States youth population cohort studies. When comparing siblings, moving from the 25th to 75th percentile of adolescent cognitive ability was associated with only a 0.06 kg/m2 decrease in BMI.
