Prevalence and Factors Associated with Diabetes Screening Uptake among Adults in Zambia: Evidence from The 2024 Zambia Demographic and Health Survey
Based on the 2024 Zambia Demographic and Health Survey, diabetes screening uptake among adults in Zambia remains low at 14.7% and is significantly influenced by socioeconomic status, age, health insurance coverage, and the presence of comorbidities like hypertension.

Imagine the human body as a bustling city. For years, the city's health inspectors have been very good at catching infectious diseases like the flu or a cold—those are the sudden storms that knock on the door and demand immediate attention. But there's a different kind of trouble brewing: a slow, silent leak in the pipes called diabetes. It's a condition where the body struggles to manage sugar, and if left unchecked, it can cause massive damage over time. The big question for health officials isn't just "How many people have this leak?" but "How many people have actually asked an inspector to check their pipes?" This is called screening. It's the act of getting your blood sugar measured by a doctor before you even feel sick. The World Health Organization suggests that catching this leak early is the best way to stop the city from flooding later, but in many places, people are still waiting until the water is ankle-deep before calling for help. This paper dives into the data to see who in Zambia is getting their pipes checked and, more importantly, who is being left out.
The researchers behind this study decided to take a giant, magnifying glass to the 2024 Zambia Demographic and Health Survey. Think of this survey as a massive snapshot of the entire country, capturing the lives of 26,508 adults. Instead of just guessing, they looked at the actual numbers to answer a simple question: How many people in Zambia have ever had their blood sugar checked by a healthcare worker? The answer, they found, is a bit of a wake-up call. Only about 14.7% of the people surveyed had ever been screened. That means if you walked into a room with 100 random Zambian adults, fewer than 15 of them would have had their blood sugar measured by a professional. It's like a city where only a tiny fraction of the population has ever called a plumber to check for leaks, even though the risk of a flood is rising.
But the story gets more interesting when we look at who is getting checked. The data reveals a clear pattern of "haves" and "have-nots" when it comes to health checks. If you are older, specifically 45 years and above, you are much more likely to have been screened—about 28.9% of people in this age group have had their blood sugar checked. It seems that as people get older, they visit the doctor more often, perhaps for other reasons, and the opportunity to check for diabetes slips in. Similarly, if you are female, have a higher level of education, live in a city (urban area), or have health insurance, your chances of getting screened jump significantly. For instance, those with health insurance had a screening rate of 38.1%, while those without it were much lower.
The study also points out some surprising gaps. Men are less likely to get screened than women, with odds of being screened dropping by about 25% for males. The researchers suggest this might be because men are often less likely to visit doctors for preventive care, perhaps due to cultural ideas about strength or simply not feeling the need until they are very sick. Another group that is being missed is smokers; they are less likely to get screened, possibly because they avoid the doctor to avoid hearing bad news about their lifestyle.
Geography plays a huge role too. If you live in Lusaka, the capital city, you are far more likely to have been screened compared to those in other regions. The study found that residents of all other regions had lower odds of screening compared to Lusaka. It's as if the health inspectors are mostly parked in the city center, leaving the rural neighborhoods waiting for a visit that hasn't happened yet.
So, what does this all mean? The paper doesn't claim to have solved the mystery of diabetes, but it does suggest that the current system is missing a huge chunk of the population. The low screening rate of 14.7% indicates that the "silent leak" is going undetected in millions of people. The authors argue that to fix this, we can't just wait for people to show up at the clinic. Instead, we need to bring the checks to the people. They suggest that screening should be mixed into other health services, like checking blood pressure or caring for HIV, so that no one slips through the cracks. They also emphasize that we need to reach out to men, younger people, and those in rural areas with better information and easier access to care. Until we do, the city of Zambia will continue to have too many people waiting for the water to rise before they finally call the plumber.
