Half of the world’s population suffers from headaches
Twice as many women as men suffer from headaches. Migraines are the leading cause of disability for people under the age of 50.
Every single day, one in six people on the planet has a headache.
Half of them experience pain severe enough to be considered migraines.
Headaches can be painful and disabling.
Some people get headaches due to stress. Other headaches result from overusing medications like painkillers.
Researchers reviewed 357 articles
A research team has arrived at the findings through a large-scale review of several hundred publications.
The review highlights just how common headache struggles are.
“Headaches are a real and extremely frequent disorder. The condition is widespread in countries everywhere – although there can be differences,” says Lars Jacob Stovner, a professor at NTNU.
Stovner and his colleagues identified 357 articles published between 1961 and the end of 2020.
The articles covered different countries and time periods, and varied in their analytical approaches. Nevertheless, the research team was able to analyse the data to explore the prevalence of headache disorders around the world.
The results indicate that more than half of the world’s population has an active headache disorder.
Confirms previous findings on headaches
Headache prevalence is described as having experienced some type of headache over the past year. Further analyses revealed that just under 16 per cent of people around the world had a headache on any given day.
While many of the studies did not report specific headache types, those that did suggest that approximately seven per cent of the global population experience migraines on any given day, and almost nine per cent experience a tension headache.
The review also highlighted that the incidence of headaches varied by gender, with 17 per cent of women suffering from migraines in a given year, compared with 8.6 per cent of men.
Getting headaches for 15 or more days a month was also much more common in women.
Stovner says the general findings are consistent with previous estimates of the incidence of headaches, including the Global Burden of Disease Study.
Working age adults are hardest hit
Stovner and his colleagues have previously found that migraines are the leading cause of disability for people under the age of 50.
“A lot of other bodily pains increase as we approach retirement age. Migraines and headaches are most prevalent in the most active years of our life,” says Stovner, who also works with the Global Campaign against Headache.
He adds that headaches can have multiple causes – from an individual’s genetics to stress, sleep problems and overuse of medication.
Stovner emphasises that many options exist for preventing headache disorders or treating them when they occur.
“Headache woes are something the health service needs to take seriously. We have to inform the public, decision-makers and health services about this huge public health problem. We need to put a good system into place that gives everyone with these ailments access to good treatment, as well as to knowledge that enables them to reduce the negative impact as much as possible,” he says.
