A new one Reconsideration Evidence that 52% World population Is affected by a Headache disorder Each year, 14% of migraines occur, according to the medical journal The Journal of Headache and Pain.
The Headache They are one of the most common and disabling conditions worldwide. However, the prevalence of headache studies can vary widely among them Method And samples, which may affect how the overall headache rate is estimated.
Authors from the Norwegian University of Science and Technology reviewed 357 publications to estimate the global incidence of headaches between 1961 and the end of 2020. Most of the publications considered in the review have been reported Adults Between the ages of 20 and 65, but some included Teenager And children up to 5 years, Old man 65 years old.
Based on an earlier report from 2007, Lars Jacob Stowner and colleagues They measure The The difference They have reviewed the research methodology. They modeled these differences methodically and how they relate to estimating its prevalence Headache. Most studies have reported a tendency to headaches in the last year. However, some studies have reported Extension Lifelong headaches and more Very short durationIncluding headaches on the last day.
Based on 357 publications reviewed, the authors estimate that 52% of the world’s population Headache disorder In a given year, 14% reporting a Migraine26% report tension-type headaches and 4.6% report headaches on 15 or more days per month.
Of the 12 studies that reported headaches in the past day, the authors estimated that 15.8% of the world’s population had a headache on any given day, of which about half reported migraine (7%).
Lead author Lars Jacob Stovner says, “We have found that the prevalence of headache disorders is higher worldwide and different types of burdens can affect many.” We have to try Reduce this burden through prevention and advanced treatment. To measure the impact of these efforts, we need to be able to monitor the prevalence and burden on society. Our study helps us understand how to improve our methods. ”
All types of headaches are more common in women than in men, especially migraines (17% in women vs. 8.6% in men) and 15 or more headaches per month (6% in women compared to 2.9% in men).
The author also investigates Union In Study method and headache estimation. Some of the different measures analyzed by the authors, such as screening questions, sample size, year of publication, and ways to apply diagnostic criteria, among others, explain the 29.9% variability of migraine estimates and less for other headache disorders. This suggests that there may be others Systematic reasons Let the elders explain Variety In study.
When modeling changes in migraine outbreak estimates, the year of publication of the study was associated with 6% of the variability in headache estimates, with higher prevalence estimates associated with recent publications.
The year of publication was not associated with other types of headaches. The authors suggest that this may be a reflection The real change, As migraines have become more common in the last three or four decades. Alternatively, this research may suggest that diagnostic methods have been developed for migraines.
Most of the writers also admit Publications They reviewed it from high-income countries with good health care, so it may not be reflected in all countries. Further research into low- and middle-income countries will help present more accurate global estimates.
However, in order to obtain data from as many countries as possible, the authors drew on extensive studies that sampled participants outside of clinical settings, such as company employees, university students, and hospital staff, among others.
Lars Jacob Stovner said, “Compared to our previous report and global estimates, the data suggest that the rates of headaches and migraines are increasing. It would be premature for the headaches to increase. ”
He adds that “what is clear is that, in general, there is a high prevalence of headache disorders worldwide and this can be a big burden. Analyzing the different causes of headaches may also be interesting in the future which varies between groups to guide prevention and treatment.” Treatment More effectively. ”
The author concludes that Study Provides a baseline for How to estimate the rate of headaches around the world And future research could build on this to improve methods of measuring the success of interventions.
