Knowledge, Attitude, and Practice Regarding Tuberculosis Among University Students in Aden, Yemen: A Cross-Sectional Study with Advanced Statistical Analysis
This cross-sectional study of 302 university students in Aden, Yemen, reveals dangerously inadequate knowledge, attitudes, and practices regarding tuberculosis—particularly among males and non-medical students—and utilizes advanced statistical modeling to demonstrate that attitude partially mediates the link between knowledge and practice, thereby identifying distinct student profiles to guide targeted, dual-focus interventions.

Imagine the human body as a bustling city, and inside that city, there's a sneaky, invisible burglar called Tuberculosis (or TB for short). This burglar doesn't just knock on doors; it travels on the wind, hitching a ride on tiny droplets when someone coughs or sneezes. For a long time, scientists have known that if you want to stop this burglar, you can't just lock the doors; you have to teach the city's residents how to spot the signs, how to react, and how to keep the neighborhood safe. This is the science of "Knowledge, Attitude, and Practice" (KAP). Think of Knowledge as having a map of the city and knowing where the burglar hides. Attitude is your mindset: do you think the burglar is scary and worth fighting, or do you ignore it? And Practice is the actual action: locking the windows, wearing a mask, or calling the police when you hear a suspicious noise. If you have the map but don't believe the burglar is real, or if you believe it but don't know how to lock the windows, the city stays in danger. This is why researchers are always checking to see if the people living in the city actually know the rules, care about the threat, and are taking the right steps to stay safe.
Now, picture a group of young adults in a university in Aden, Yemen. These students are the future leaders, doctors, engineers, and teachers of their country. A team of researchers decided to check if these students had the right "city maps" and were taking the right actions against the TB burglar. They didn't just ask a few questions; they used some very fancy digital tools to analyze the answers, looking for hidden patterns and connections that a simple glance might miss.
Here is what they found: The situation is a bit worrying. Out of every 100 students they asked, only about 46 had a good "map" (knowledge) of the disease. About 55 had a positive mindset (attitude) about fighting it, but only 38 were actually taking the right protective steps (practice). It's like having a group of people who know a fire is dangerous and agree they should be safe, but fewer than half of them actually know how to use a fire extinguisher or where the exits are.
The researchers dug deeper and found some clear reasons for this gap. They discovered that being a male student or studying a subject that isn't related to medicine (like engineering or business) made it much more likely that a student didn't know the basics. In fact, male students were more than twice as likely to have poor knowledge compared to female students, and non-medical students were nearly four times as likely to be in the dark compared to their medical school peers. Another big clue was age in school: the younger students (freshmen and sophomores) knew significantly less than the seniors, suggesting that knowledge often comes with time and experience at university.
One of the most critical things the study uncovered was a specific blind spot. When asked, "If you have a cough that won't go away for more than two weeks, what should you do?" only about 22 out of 100 students knew the answer: go see a doctor immediately. This is a huge problem because that specific cough is the main alarm bell for TB. Similarly, only about 40 out of 100 knew that treatment takes a long time (6 to 9 months), which is crucial because stopping early can make the burglar stronger and harder to catch later.
The study also used a special mathematical tool (called a ROC curve) to find the "sweet spot" for knowledge. They found that students didn't need to be experts to take good action. If a student got about 14 out of 22 questions right (roughly 64%), they were likely to practice good prevention habits. This suggests that you don't need a PhD to be safe; you just need the basics.
Furthermore, the researchers found that having knowledge doesn't automatically lead to action. It's like having a recipe (knowledge) doesn't mean you'll cook the meal (practice) unless you also want to cook (attitude). The study showed that attitude acts as a bridge: about 40% of the time, knowledge helps you act because it changes how you feel about the disease. If you know the facts but still feel scared or think the disease isn't a big deal, you won't take the right steps.
Finally, the team used a computer method to sort the students into three distinct groups, like sorting players in a video game by their skill levels:
- The "TB-Aware" (18.5%): These are mostly older medical students who know the facts, have a positive attitude, and take good care. They are the "pro players."
- The "Moderately Informed" (54.3%): This is the biggest group. They know some things and have okay attitudes, but they aren't fully consistent in their actions. They are the "average players" who could use a little boost.
- The "TB-Ignorant" (27.2%): This group is the most at risk. They are mostly younger, male, non-medical students who know very little, have less positive attitudes, and rarely take protective actions. They are the "newbies" who need the most help.
The researchers concluded that to stop the TB burglar in Yemen, universities can't just hand out pamphlets. They need to target the "newbies" specifically, especially the young men in non-medical classes. They need to teach them the specific alarm signs (like the two-week cough) and help them understand that fighting TB is something they can actually do. The study suggests that fixing the knowledge gap is important, but fixing the attitude gap is just as critical, because you need both to get the job done.
