Epidemiological Profile and Determinants of Abortion Cases in Ilam Province, Western Iran: A Two-Year Population-Based Registry Study
This two-year population-based registry study in Ilam Province, western Iran, characterizes the epidemiological profile of 1,962 abortion cases, revealing that spontaneous abortions predominate, chronic maternal diseases like thyroid disorders are significant correlates, and improved prenatal care is associated with a lower likelihood of induced abortion, while highlighting geographic disparities and a 30% increase in recorded cases likely due to enhanced surveillance.

Pregnancy is a journey that does not always reach its destination. In medical terms, the loss of a pregnancy before it can sustain life outside the womb is known as abortion, a broad category that includes both miscarriages, which happen naturally, and induced terminations, which are performed for medical or legal reasons. While these events are a common part of human reproduction, understanding exactly how often they occur and why is difficult, especially in places where laws restrict the practice or where records are kept in scattered, disconnected ways. In many regions, the true picture is hidden behind incomplete data, making it hard for health systems to know where to focus their care. Researchers care deeply about this because knowing the patterns of pregnancy loss allows them to identify risk factors, such as chronic illnesses or lack of medical checkups, and to build better support systems for women and families.
In the western Iranian province of Ilam, a team of researchers set out to clear away the fog of incomplete data by looking at a complete, two-year record of every abortion case registered across the entire region. They examined a vast digital ledger maintained by the local health authority, which captured events from all twelve counties in the province between March 2023 and March 2025. This was not a study based on surveys or a few hospitals; it was a census of the available records, covering nearly two thousand cases. The goal was to move beyond guesswork and describe the real faces of these losses: who the women were, how far along the pregnancies were, and what health conditions they carried. By looking at the whole province, the team hoped to find patterns that smaller studies might miss, particularly regarding the role of chronic diseases and the uneven access to prenatal care in this border region.
The researchers found that the women in this study were, on average, thirty-four years old, with a significant portion being thirty-five or older. Most of the pregnancies ended early, with nearly seventy-one percent occurring in the first three months, averaging just over eleven weeks of gestation. When the team looked at the types of losses, the vast majority were spontaneous, meaning they happened naturally without medical intervention, accounting for more than eighty percent of the cases. A smaller but notable group involved legal terminations approved for specific medical reasons, while a tiny fraction were ectopic pregnancies, where the embryo implants outside the uterus. The data also revealed that nearly thirty percent of the women had experienced a prior abortion, and almost thirty percent of the women were living with an underlying health condition. Among these conditions, thyroid disorders were the most common, followed by minor forms of thalassemia, a blood disorder, and other issues like high blood pressure and diabetes.
A striking pattern emerged when the researchers looked at the timing and location of these events. The number of recorded cases jumped by thirty percent from the first year of the study to the second. However, the authors suggest this was not necessarily a sudden surge in pregnancy losses. Instead, it likely reflected an improvement in how the health system was catching and recording these cases, as the rate of women receiving prenatal care also rose during the same period. This suggests that better record-keeping can make numbers go up without the actual situation getting worse. The study also highlighted that geographic disparities were real and significant. Some counties had much lower rates of prenatal care coverage than others, pointing to structural barriers in the health system rather than individual choices.
When the team tried to figure out what specifically made a pregnancy more likely to end in a legal termination versus a spontaneous loss, they found that the length of the pregnancy mattered. For every additional week a pregnancy continued, the odds of it being a legal termination increased. Conversely, women who had received at least one prenatal care visit were less likely to have a legal termination compared to a spontaneous loss. Interestingly, factors that are often assumed to be major drivers, such as a woman's body mass index, her age, or the presence of underlying chronic diseases, did not show a strong independent link to the type of abortion once other factors were taken into account. The study did find, however, that chronic diseases were a significant characteristic of the population, with thyroid dysfunction being the most common condition reported, suggesting these health issues are prevalent among women experiencing pregnancy loss in this region, even if they did not statistically predict the specific type of loss in the final analysis.
The researchers concluded that while the rising number of recorded cases might look alarming at first glance, it is more likely a sign of a health system that is finally seeing the full picture. The real story lies in the gaps: the women in underserved counties who are not getting prenatal care, and the women with thyroid or blood disorders who are not being screened before or during pregnancy. The study does not claim to have solved the problem of pregnancy loss, but it has provided a clear map of where the risks are concentrated. It suggests that the path forward involves strengthening the reach of prenatal care into remote areas and making routine screening for chronic conditions a standard part of care for women of reproductive age. By addressing these specific, measurable gaps, health officials in Ilam and similar regions can hope to improve outcomes for women and families, turning a fragmented picture into a coherent strategy for better health.
