Big head, big reason to care.
Does your baby have a large head?
Well, that’s quite awesome, because it would seem that babies with larger heads are more intelligent.
There’s no doubt to the fact that we’ve all heard the usual stereotype that associates people with larger heads with more intelligence. However, a study from Edinburgh University suggests that this stereotype just might be true.
The study was conducted in 2016, and it took data from 10,000 residents in the United Kingdom, all of whom were between the ages of 37 and 73.
The data was gathered by U.K. Biobank, a health resource that keeps data from 502,655 people, all between the aforementioned ages. The participants for the study were recruited between 2006 and 2010. They underwent physical and cognitive assessments, and they as gave samples of their saliva, urine and blood.
The participants of the study also gave detailed information about their backgrounds and the lives they lead, and this is how the scientists formed a link between the size of the head and intelligence. The study also found out that babies who are born with bug heads might turn out to be smarter in real life.
In a statement, the researchers said, “Highly significant associations were observed between the cognitive test scores… and a lot of polygenic profile scores, such as intracranial volume, the circumference of an infant’s head and the cognitive ability of a child”
Babies with large heads were found to actually be more likely to get a degree. The study also revealed that people who had big heads ended up scoring higher on verbal and numerical reasoning exercises. It also found that there are 17 significant genes which can affect the function of the brain and impact the physical and mental health of people.
Professor Ian Deary of the Edinburgh University, who was the lead researcher of the study, said, “In addition to the fact that there are some shared genetic influences between some mental and physical health states and cognitive skills, the study also discovered that cognitive skills share some genetic influences with the size of the brain, the shape of the body and some educational attainments”
Researchers said that there were a lot of findings from the study, so much so that it wasn’t possible to fully discuss the implications that they would have. However, one fact was made abundantly clear
A statement by researcher Saskia Hagenaars reads, “The study supports an existing theory which says that people who have better overall heath are likely to have significantly higher levels of intelligence and mental capacity”
According to a report by the Huffngton Post, the average baby born in the United States has a circumference of 13.5 to 14.1 inches.
However, there are also some people who believe that the size of a baby’s head can’t conclusively determine how intelligent the baby is going to be.
Diane Sacks of Today’s Parents wrote, “A large cranium could just be a reflection of a mom or dad who had a bigger-than-average head. One thing is for certain; a large cranium doesn’t indicate a learning disorder or a disability of any sort”
There are a few circumstances where a large head might be a sign of health issues as well.
Sacks said, “The most important information here is whether the circumference of the baby’s head has been growing along the same growth pattern ever since the baby was born. That’s why measurements are taken and the doctor follows its growth on a monthly basis”
