Twenty-five years of maternal, neonatal, child and reproductive health measurement in Ethiopia: a harmonized trend and subnational inequality analysis of six Demographic and Health Surveys, 2000–2025

Imagine you are trying to understand how a giant, complex machine is running over time. In the world of public health, this machine is a whole country's population, and the "gears" are things like how many babies are born, how many mothers get help during childbirth, and how many children survive their first few years. To see if the machine is getting better, scientists use special surveys called Demographic and Health Surveys (DHS). Think of these surveys as giant, incredibly detailed snapshots taken of a country's families every few years. By lining up these snapshots one after another, researchers can create a time-lapse movie of a nation's health. The big question isn't just "Is the country getting healthier?" but "Is everyone getting healthier, or are some groups being left behind while others zoom ahead?" This is the heart of population health: measuring progress not just by the average, but by looking at the gaps between the richest and poorest, or the cities and the remote villages.

This paper takes a massive, twenty-five-year time-lapse movie of Ethiopia, stitching together six different snapshots taken between the years 2000 and 2025. The authors, Asrat Genet Amnie and Assaye Kassie Nigussie, acted like health detectives, harmonizing all the data so they could compare apples to apples across a quarter-century. They looked at twenty different health indicators, from how many women use birth control to how many children get vaccinated. Their main finding is a story of two different eras. For the first part of the movie, Ethiopia was a superstar, making huge, dramatic leaps forward. But around 2016, the movie hit a pause button. Some of the most important gears stopped turning, and in a few cases, they even started spinning backward. While the country achieved massive success in getting skilled doctors to help with births, other areas like childhood vaccinations and nutrition have stalled or regressed. Perhaps most importantly, the paper reveals that the "average" Ethiopian health score is a lie; the reality is a patchwork quilt where some regions are thriving like a bustling city, while others, particularly in the pastoralist areas, are struggling with gaps so wide they feel like a different world entirely.

The Great Health Time-Travel

Imagine you have a time machine that can show you the health of a country over twenty-five years. That is exactly what this paper does for Ethiopia. The researchers gathered data from six different national surveys (2000, 2005, 2011, 2016, 2019, and 2024–25) to create a single, continuous story. They wanted to see if the country was getting better at keeping mothers and children alive and healthy, and if that progress was shared by everyone or just a lucky few.

The Good News: A Giant Leap Forward
In the early days of this story (around the year 2000), Ethiopia was like a runner who had just tripped and fallen. Only about 6% of mothers had a skilled doctor or nurse helping them give birth. By 2024–25, that number had exploded to 64.0%. That is more than a tenfold increase! It's as if the country went from having one doctor for every village to having a whole team of helpers.

Similarly, the number of children dying before their fifth birthday dropped dramatically. In 2000, for every 1,000 babies born, 166 would not survive to age five. By 2024–25, that number fell to 51. That is a 69% drop. The country also got better at family planning. In 2000, only 6% of married women were using modern birth control. By 2016, that had risen to 41%, and it settled at 34.5% in the most recent survey. This means fewer unwanted pregnancies and more control for women over their own families.

The Plot Twist: The Pause Button
However, the story gets complicated around 2016. If you were watching a graph of Ethiopia's health progress, you would see a steep hill going up, and then, right around 2016, the hill flattens out. Some lines even start to go down.

• Vaccines: In 2016, 39% of children had received all their basic vaccines. By 2024–25, that number dropped to 30%. It's like a school that had a perfect attendance record suddenly seeing many students start skipping class.
• Birth Control: The use of modern birth control peaked in 2019 but then dropped back down to 2016 levels by 2024–25.
• Stunting: This is when children are too short for their age because they haven't gotten enough good food over a long time. In 2016, 38% of children were stunted. By 2024–25, it was still stuck at 37–40%. It's as if the country fixed the short-term hunger but couldn't solve the long-term problem of getting enough nutritious food.

The authors suggest that these reversals might be linked to tough times in the country, including conflicts, people being forced to move from their homes, and the global pandemic, which disrupted health services.

The Inequality Map: Two Different Worlds
The most striking part of the paper is how uneven the progress is. Imagine Ethiopia not as one big country, but as a map with some areas glowing bright and others dark.

• The "Frontier" Cities: Places like Addis Ababa (the capital) and Dire Dawa are like the "frontier" of health. In Addis Ababa, 98.2% of mothers had a skilled birth attendant. It's a place where almost everyone gets the care they need.
• The "Lagging" Regions: On the other side of the map, in regions like Somali and Afar, the numbers are much lower. In Somali, only 35.0% of mothers had a skilled birth attendant. The gap between the best region and the worst region for some health checks is huge—up to 82 percentage points for prenatal care.
• The Vaccination Gap: The inequality here is even wilder. In the best region, nearly 70% of kids are fully vaccinated. In the worst region, only 5.5% are. That is a difference of more than twelve times!

The researchers also noticed something interesting about where the problems are. The lack of vaccines and the lack of prenatal care often happen in the same places (the pastoralist regions). However, the problem of stunted growth (malnutrition) is a bit different. While the pastoralist regions struggle with vaccines, the highest rates of stunting are actually found in a different region called Benishangul-Gumuz. This tells us that fixing the health system isn't enough; we also need to fix food security and water in different areas to stop children from being stunted.

What This Means for the Future
The paper concludes that Ethiopia has done an amazing job building the "roads" to health over the last twenty-five years. They got more people to the hospital and more kids vaccinated than ever before. But now, the country has hit a wall. The easy wins are over. To keep improving, they can't just build more roads; they need to make sure the cars on those roads are high-quality and that everyone gets to drive, not just the people in the big cities.

The authors suggest that the next twenty-five years need to focus on three things:

1. Quality over Quantity: It's not enough to just see a doctor once; women need to finish all their prenatal visits, and babies need to get all their vaccines.
2. Fixing the Gaps: The huge differences between regions like Addis Ababa and Somali need to be closed.
3. New Strategies: Since stunting and vaccine gaps don't always happen in the same places, the government needs different plans for different areas.

In short, Ethiopia's health story is a mix of a massive success story and a warning sign. The country proved it can make huge leaps, but it also showed that without constant effort, progress can stall, and the gap between the rich and the poor can become a canyon. The data is clear: the next chapter of Ethiopia's health story depends on making sure no one is left behind.
