Correlates of DHS-defined infecund/menopausal status among Nigerian women aged 45-49: Evidence from the 2024 Nigeria Demographic and Health Survey
Using data from the 2024 Nigeria Demographic and Health Survey, this study reveals that DHS-defined infecund/menopausal status among women aged 45–49 is strongly associated with marital history, parity, and socioeconomic factors, though these cross-sectional correlations should not be interpreted as causal due to the survey's reliance on self-reported rather than clinically confirmed menopause.

Imagine a large room filled with women aged 45 to 49. If you asked a casual observer to look at this group, they might assume everyone in the room has already "clocked out" of their reproductive years, like a factory that has shut down for the day. They might assume everyone is done having children and has reached menopause.
This study is like a detective walking into that room with a clipboard, checking the actual status of every woman to see if that assumption is true. The researchers used data from the 2024 Nigeria Demographic and Health Survey (NDHS) to take a snapshot of 3,237 women in this age group.
Here is what they found, broken down into simple concepts:
1. The "Factory" Isn't Closed Yet
The study found that the room is actually quite mixed.
- The Majority: About 54% of the women were classified as "infecund" or "menopausal" (the factory is closed).
- The Minority: However, about 41.5% were still "fecund" (the factory is still running and could produce).
- The Exceptions: A tiny few were currently pregnant or had just given birth recently.
The Takeaway: You cannot treat all women in their late 40s as if they are finished with childbearing. They are a diverse group, not a uniform block.
2. The "Life Story" Matters More Than Age
The researchers didn't just look at how old the women were; they looked at their life stories. They found that a woman's reproductive status is heavily influenced by her social history, much like how a person's career path is shaped by their education and job history.
Marriage is the Biggest Clue: The strongest signal of whether a woman was "done" or still "active" was her marital history.
- Women who had never been married were the most likely to still be fertile.
- Women who were currently married or had been married before were much more likely to be classified as menopausal.
- Analogy: Think of marriage as a long journey. The longer you've been on the journey (or the more times you've traveled it), the more likely you are to have reached the "end of the line" compared to someone who hasn't started the trip yet.
Money and Education: Women with more education and more money were slightly more likely to be in the "fertile" group, while women with less education and less money were more likely to be in the "menopausal" group. However, this link was a bit shaky and depended on other factors.
Ethnicity: Where a woman comes from (her ethnic group) mattered. Some groups were more likely to be classified as menopausal than others, but this was likely due to cultural differences in marriage and family life, not just biology.
3. The "Contraception Confusion"
One of the most interesting parts of the study was looking at birth control.
- Women using birth control were much less likely to be classified as "menopausal."
- Why? The study explains that this isn't because birth control stops menopause. It's more like a "smoke detector" that is going off. If a woman is using birth control, it usually means she thinks she can still get pregnant, so she is protecting herself. If she thinks she can't get pregnant (because she's menopausal), she stops using birth control.
- When the researchers added this "birth control" factor into their math, some of the other links (like education and money) became weaker. This suggests that what we see as "menopause" in these surveys is often just a reflection of whether a woman is still trying to avoid pregnancy.
4. What This Is (and What It Is Not)
The authors are very careful to draw a line in the sand:
- What it is: This study looks at a "Demographic" label. It's a category used by survey takers to figure out if a woman is exposed to the risk of pregnancy.
- What it is NOT: It is not a medical diagnosis. Just because the survey says a woman is "infecund/menopausal" doesn't mean a doctor has confirmed she has gone through menopause (which is medically defined as 12 months without a period).
The Bottom Line
Think of women aged 45–49 not as a group that has all retired at the same time, but as a group at different stages of a long journey.
- Marriage history is the most reliable map for where they are on that journey.
- Social factors (money, education, ethnicity) shape the path they took.
- Birth control use tells us who still thinks they are on the road.
The study concludes that we shouldn't assume all women in their late 40s are done having children. We need to look at their individual life stories to understand where they really stand.
