Study finds strong genetic component to childhood obesity

Chris Engel 3/26/136:23 PM

"Previous research has shown that obesity runs in families, and twin studies suggest that this is largely due to genetic factors, with heritability estimates over 50%. 32 genes have been identified as risk factors for obesity but previous analyses suggest that these genes alone cannot fully explain the high level of heritability in childhood obesity, as together they explain only 2% of individual differences in childhood body weight. This has led to a problem of 'missing heritability'...."
