A new study has suggested that babies with large heads are more intelligent and more likely to go on and have university degrees.
Babies with large heads are more intelligent and more likely to go on and have university degrees, a new study has suggested.
The study, carried out by health charity UK Biobank, suggested that the brain size and head circumference of babies was linked to how likely a person is to have a university degree.
According to your baby’s ‘Red Book’, the average size of newborn’s head is 35cm for girls, and 36cm for boys.
Babies with larger heads were apparently also more intelligent, having ‘higher scores on verbal-numerical reasoning’, the researchers found. The scientists looked at data from more than 100,000 Brits in the UK Biobank database.
UK Biobank gathered information from volunteers in the UK aged between 37 and 73, from 2006 to 2010. Scientists studied the data to see if there were any links between genes, IQ and health.
Participants were also asked to provide detailed information about their lifestyle and background, and blood, saliva and urine samples.
Big heads, big brains
While the study, which was published in the journal of Molecular Psychiatry, suggested there was a strong link between genes and intelligence, the size of a baby’s head was an unexpected discovery.
Professor Ian Deary of Edinburgh University led the study and told Neuroscience News:
‘In addition to there being shared genetic influences between cognitive skills and some physical and mental health states, the study also found that cognitive skills share genetic influences with brain size, body shape and educational attainments.’
