Who gets screened? Prevalence and determinants of cervical cancer screening among women aged 15–49 in Malawi and Zambia: a cross- sectional analysis of the 2024 Demographic and Health Surveys
This study analyzes 2024 Demographic and Health Survey data to reveal that cervical cancer screening prevalence remains low (under one-third) among women aged 15–49 in Malawi and Zambia, with uptake significantly influenced by age, socioeconomic status, HIV status, and access to health services, highlighting the urgent need for targeted interventions to address these disparities.

Imagine the human body as a bustling city, and the cervix as a crucial checkpoint gate. Every so often, health inspectors need to stop by and check if the gate is healthy or if any troublemakers (cancer cells) are trying to sneak in. This check-up is called cervical cancer screening.
A new study took a giant snapshot of this city in two neighboring countries, Malawi and Zambia, looking at nearly 30,000 women aged 15 to 49. The researchers wanted to know: Who is actually getting their gate checked, and who is skipping the appointment?
The Big Picture: A City with Many Unchecked Gates
The news isn't great, but it's not a total blackout either. The study found that in Malawi, only about 29.7% of women have ever been screened. In Zambia, it's slightly better at 31.6%.
Think of it like a concert where the organizers promised 100% attendance, but only about one out of every three fans actually showed up. Even though both countries have been trying hard to fix this with special programs for the last two decades, the "gate checks" are still happening far too rarely.
Who Shows Up for the Check? (The High-Frequency Visitors)
The study used a massive database to figure out who is most likely to get screened. It turns out that certain groups are much more likely to visit the health inspectors.
- The Older Crowd: Women aged 40–49 are the most likely to get checked. In Malawi, 43.4% of them have been screened, and in Zambia, it's 47.1%. It's like how older drivers might be more careful about getting their car inspected because they know the road better.
- The Wealthy and Employed: If a woman has a formal job or belongs to the richest group of people, she is much more likely to get screened. In Malawi, the richest women had a 36.8% screening rate, while the poorest were at 23.5%. Money seems to act like a bus ticket that makes it easier to get to the clinic.
- The "Health Insurance" VIPs: Having health insurance is a huge booster. In Zambia, women with insurance were 54% more likely to get screened than those without. It's like having a VIP pass that removes the cost barrier.
- The HIV-Positive Community: This is a very specific and important group. Women living with HIV are getting checked at incredibly high rates: 71.5% in Malawi and 82.1% in Zambia. The study suggests this is because these women visit doctors frequently for other treatments, so they get reminded to check their cervix too. It's like getting a free upgrade every time you visit the clinic.
- The Tech-Savvy: Women who own a mobile phone are also more likely to get screened. In Zambia, 36.5% of phone owners were screened, compared to just 22.5% of non-owners.
Who is Missing the Appointment? (The Silent Gates)
Unfortunately, the study also highlights who is being left behind.
- The Young: Women aged 15–24 are the least likely to be screened. In Malawi, only 16.9% of them have ever been checked. They might feel too young to worry about the gate, but the data shows they are the most overlooked group.
- The Rural Residents: Women living in the countryside are less likely to get screened than those in cities. In Zambia, rural women had a 28% lower chance of being screened compared to urban women. It's like the health inspectors are mostly parked in the city center, making it a long, hard walk for rural residents.
- The HIV-Negative: Here is a surprising twist. Women who do not have HIV are much less likely to get screened than those who do. In Malawi, HIV-negative women were 80% less likely to be screened than HIV-positive women. The study suggests that because HIV-positive women are reminded constantly by their doctors, the HIV-negative women slip through the cracks.
- Smokers and Muslims (in Zambia): In Malawi, smokers were 57% less likely to get screened. In Zambia, Muslim women were 66% less likely to be screened compared to Christian women. The authors suggest this might be due to cultural modesty or a fatalistic attitude toward health, but they are careful to say this is what the data suggests, not a proven fact.
What the Study Rules Out (What We Don't Know)
The researchers were very careful about what they didn't find.
- They didn't find a magic bullet: Just having a TV or listening to the radio didn't guarantee a screening in every case. While media exposure helps, it's not a magic switch that turns everyone into a regular visitor.
- They didn't prove cause and effect: Because this was a "snapshot" (a cross-sectional study), they can't say for sure that having a job causes you to get screened. They can only say they happen together. It's like seeing that people with umbrellas are often wet; the umbrella didn't make them wet, the rain did. Similarly, having money might help you get screened, but we can't prove the money caused the screening just from this snapshot.
- They didn't find that education always wins: In Zambia, having a secondary education didn't significantly increase the odds of screening compared to having no education. The "more education = more screening" rule didn't hold up perfectly there.
How Sure Are They?
The authors are quite confident in their numbers because they used data from the 2024 Demographic and Health Surveys, which are designed to represent the whole country. They ran the numbers through strict statistical tests and found that their results fit the data well.
However, they admit there are limits. Because the women told the researchers if they had been screened (self-reported), there's a small chance some people forgot or lied. Also, since they didn't follow the women over time, they can't say for certain why one group got screened and another didn't, only that the two things are linked.
The Takeaway
The study concludes that while Malawi and Zambia have made some progress, the "gate checks" are still happening far too rarely. To fix this, the authors suggest we need to target the specific groups that are missing out: the young, the rural, the poor, and those without health insurance. They also suggest that since women living with HIV are getting checked so well, we should try to use those same clinic visits to help the women who don't have HIV, so no one is left behind.
It's a clear message: We have the map, we know who is missing, and now we need to build the roads to get them to the clinic.
