Factors Influencing High-Risk Fertility Practices Among Women of Reproductive Age in Zambia: A Multilevel Analysis of the 2024 Demographic and Health Survey
Using 2024 Zambia Demographic and Health Survey data, this multilevel analysis reveals that nearly half of women of reproductive age engage in high-risk fertility behaviors, with older maternal age and lower education identified as primary individual-level risk factors driving the prevalence.

Imagine Zambia's population as a massive, bustling garden. In this garden, the "flowers" are families, and the "growing season" is a woman's reproductive years. The researchers in this paper are gardeners who noticed that many of these families are growing too many flowers too quickly, or at the wrong times, which can damage the soil (the mother's health) and the new buds (the babies). They call this "High-Risk Fertility Behavior" (HRFB).
Here is a simple breakdown of what they found, using the 2024 survey data as their map of the garden.
The Big Picture: How Common is the Problem?
The researchers looked at nearly 14,000 women (the gardeners) and found that almost half (48.4%) were experiencing at least one of these risky growing patterns. It's like saying if you walk through this garden, nearly every second plot has a plant that is struggling because it was planted too early, planted too late, planted too close together, or there are simply too many plants in one spot.
What Counts as "Risky"?
The study defines a "risky" situation as any of these four scenarios:
- The Early Sprout: Having a first baby before age 18 (like trying to harvest a crop before it's fully grown).
- The Late Bloom: Having a baby after age 34 (like trying to plant seeds when the frost is already coming).
- The Crowded Bed: Having babies less than 24 months apart (like planting seeds so close together they choke each other out).
- The Overcrowded Pot: Having four or more children (like putting too many plants in a single small pot).
The Main Drivers: Who is Most at Risk?
The researchers used a special microscope (a statistical tool called multilevel analysis) to see what makes some women more likely to have these risky patterns than others.
- Age is the Biggest Factor: The older a woman gets, the more likely she is to be in a "risky" situation.
- Analogy: Think of age like a snowball rolling down a hill. The further down the hill (older age) the snowball rolls, the bigger it gets. Women aged 35–49 were nearly twice as likely to have risky fertility patterns compared to women aged 15–24. This is often because they have had more children over time or had them closer together.
- Education is the Shield: Education acts like a strong fence protecting the garden.
- Women with secondary or higher education, and women whose husbands are educated, were much less likely to have risky fertility.
- Analogy: Education gives a woman a better "instruction manual" for her garden. It helps her plan when to plant and how many seeds to use, rather than just letting nature take its course.
- Money and Work: The results here were a bit surprising.
- Work: Women who were employed were slightly more likely to have risky fertility.
- Money: Interestingly, the poorest women were slightly less likely to have risky fertility in the final analysis compared to the richest, though the poor still face many other health challenges.
- Analogy: It's like finding that people with jobs are planting more seeds than those without. The researchers suggest this might be because women often start using birth control after they have already had several children or faced a difficult pregnancy, rather than planning ahead.
The Surprising Twist: Contraceptives
The study found that women currently using modern contraception were actually more likely to be in a high-risk category.
- The Metaphor: Imagine a gardener who realizes their garden is overrun with weeds after the weeds have already taken over, and then they buy a weed killer. The study suggests many Zambian women are using contraception as a "fix-it" tool after they have already had too many children or had them too close together, rather than as a "prevent-it" tool from the start.
The Location Myth: City vs. Country
You might think that living in the city (urban) is safer than the countryside (rural).
- The Finding: When the researchers looked at the raw numbers, rural women did have more risky fertility. However, once they accounted for education and money, the location itself didn't matter much.
- Analogy: It's not that the "soil" in the countryside is bad; it's that the gardeners in the countryside often have fewer tools (education) and less fertilizer (money). If you gave a city gardener and a country gardener the exact same tools and knowledge, their gardens would look about the same. The risk comes from the tools, not the location.
The "Community" Factor
The researchers checked if the specific neighborhood or village a woman lived in made a difference.
- The Finding: Almost zero.
- Analogy: Imagine a row of houses. You might think the "vibe" of the street determines if a family has too many kids. This study says the "vibe" of the street doesn't matter. The decision is made entirely inside the individual household. The risk is personal, not communal.
What Should Be Done?
Based on these findings, the paper suggests:
- Focus on Education: Keep girls in school and educate their partners. This is the strongest "fence" against risky fertility.
- Help Older Women: Don't ignore women who are older and still having children; they need specific support to space their babies safely.
- Change the Timing of Contraception: Instead of waiting until a woman has had many children to offer birth control, offer it earlier, before the "garden" gets overcrowded.
- Use Past Experiences: If a woman has had a pregnancy loss (a terminated pregnancy), use that moment to gently guide her toward better family planning for the future.
In short: The paper tells us that nearly half of Zambian women are facing fertility risks, mostly driven by age and a lack of education. The solution isn't just about building more clinics in the countryside; it's about empowering individual women with knowledge and ensuring they can plan their families before the risks start to pile up.
