Non-febrile headache burden among secondary school students in Bukavu, Democratic Republic of Congo: prevalence, clinical phenotype, and sex differences
This 2019 cross-sectional study of 400 secondary school students in Bukavu, DRC, reveals a high 6-month prevalence of non-febrile headaches (67.5%), predominantly migraines, which significantly impact academic performance and show marked sex differences with females experiencing more frequent and severe symptoms, highlighting a critical unmet need for screening and preventive care in this low-resource setting.

Imagine your brain is a high-performance engine, and a headache is like a warning light flashing on the dashboard. Sometimes that light means the engine is overheating because you ran out of fuel (like skipping breakfast), other times it's a glitch in the wiring caused by stress, or maybe the engine is just running too hot because you've been driving too long without a break. In the world of science, doctors call these "headache disorders." They aren't just annoying; for millions of people, they are a major reason why life feels heavy and hard to get through. While we know these headaches are a huge problem for adults everywhere, we know very little about how often they strike teenagers, especially in places where doctors are hard to find and life can be tough. This story is about a group of researchers who decided to peek under the hood of a specific group of teenagers to see what was making their engines sputter.
This paper is a report from Bukavu, a city in the eastern part of the Democratic Republic of Congo (DRC), where the researchers went to ask 400 secondary school students about their headaches. They didn't look at headaches caused by fevers (like from malaria or the flu); they focused on the "non-febrile" kind—the ones that just show up on their own. The team wanted to know three things: How many kids had them? What did they feel like? And were there differences between boys and girls? They used a special checklist called ICHD-3, which is like a detective's rulebook for sorting headaches into categories like "migraine" (often a throbbing, one-sided pain with nausea) and "tension-type" (often a feeling of a tight band around the head).
The results were striking. The researchers found that headaches were everywhere. Out of every 100 students, about 68 of them (specifically 67.5%) said they had had at least one non-fever headache in the last six months. That's roughly two out of every three kids. The most common type wasn't the "tight band" tension headache, which is often the most common in rich countries; instead, the top category was "possible or probable migraine," affecting 47.0% of the students with headaches. This was followed by episodic tension-type headache at 36.7%.
The study also found that being a girl made a big difference in how the headaches acted. While the total number of boys and girls with headaches was somewhat similar, the girls were much more likely to have headaches every single day. In fact, girls were 2.46 times more likely to report daily headaches than boys. They were also significantly more likely to experience the classic migraine "side effects": visual disturbances (like seeing spots or flashes) and nausea or vomiting. The girls were 1.80 times more likely to have visual issues and 2.15 times more likely to feel sick to their stomachs.
These headaches weren't just a physical pain; they were a barrier to school. The students reported that their headaches made them feel like they were doing worse in class, and 21.5% of them missed at least one day of school every month because of the pain. Despite this heavy burden, the "treatment gap" was huge. Only 7.0% of the students were taking any kind of preventive medicine to stop the headaches before they started. Most of them were just trying to cope by resting, sleeping, or taking over-the-counter painkillers like paracetamol or aspirin on their own.
The researchers also looked at what triggered these headaches. The top culprits were physical or mental exertion (48.1%) and stress or emotional upset (46.3%). Interestingly, even though nearly half of the students (47.8%) went to school without eating breakfast, very few of them (only 1.5%) blamed their headaches on fasting. This suggests that while skipping meals is a known risk factor, the students might not realize it's the cause, or perhaps the stress of their daily lives is a bigger trigger.
The authors are careful to say that this is a snapshot in time from 2019, before the global pandemic, and that they relied on students telling them about their symptoms rather than a doctor examining them. They suggest that the high number of "probable migraines" might be because young people sometimes describe their pain in ways that fit the migraine rules, even if it's not a perfect match. However, the main takeaway is clear: in this part of the world, headaches are a massive, often overlooked problem that is stopping kids from learning. The study concludes that schools need to start screening for these headaches and that local doctors need training on how to treat them, because right now, the vast majority of these students are suffering without the help they need.
