Intimate partner violence and trajectories of perinatal depressive symptoms in Ethiopia and Guinea: a multilevel mixed-effects analysis

The period surrounding childbirth is a time of profound physical and emotional transformation, yet for many women, it is also a time of heightened vulnerability to mental health struggles. One of the most common conditions affecting mothers globally is perinatal depression, a state of persistent sadness and anxiety that can begin during pregnancy and continue after the baby is born. While the biological changes of pregnancy are well understood, researchers have long known that a woman's environment plays a critical role in her mental well-being. Among the many factors that can weigh on a mother's mind, the safety of her relationship with her partner stands out as a powerful influence. When a woman faces violence or abuse from an intimate partner, the psychological toll can be severe, but understanding exactly how this violence shapes the course of her depression over time has remained difficult to pin down, especially in regions with fewer medical resources.

To explore this connection, a team of researchers traveled to two major cities in West and East Africa: Addis Ababa in Ethiopia and Conakry in Guinea. They set out to follow a group of pregnant women from their third trimester through the first few months after their babies were born. The goal was not just to take a single snapshot of their mental health, but to watch how their feelings changed over time. The researchers were particularly interested in whether women who experienced intimate partner violence—defined as physical, emotional, or sexual harm by a current or former partner—followed a different emotional path than those who did not. By tracking these women across two distinct time points, the study aimed to reveal whether the shadow of violence lingers, fades, or grows as a mother moves from pregnancy into the postpartum period.

The study involved 579 women who were married or living with a partner, with 315 from Ethiopia and 264 from Guinea. The researchers met with them while they were still pregnant, asking them about their lives, their health, and whether they had experienced any form of abuse in the year leading up to the survey. They then returned to see these same women again, roughly seven to eight weeks after they had given birth. During both visits, the women completed a standard questionnaire designed to measure symptoms of depression, which asks about feelings of sadness, worry, and inability to cope. The researchers also gathered details about the women's education, their jobs, whether they had enough food to feed their families, and how much support they felt from their communities.

The results painted a clear and concerning picture. In both countries, the experience of violence was a strong predictor of higher levels of depressive symptoms. In Ethiopia, women who reported experiencing intimate partner violence had depression scores that were, on average, more than two points higher than those of women who had not experienced violence. In Guinea, the difference was slightly smaller but still significant, with violence-exposed women scoring about one point higher. These differences were not just a fleeting reaction to a single bad day; the data showed that women who faced violence carried a heavier emotional burden throughout the entire period studied, from late pregnancy through the early weeks of motherhood. The gap between the two groups remained steady, suggesting that the psychological impact of violence does not simply vanish once the baby is born.

The study also revealed how depression changed over time for the group as a whole, and how this differed between the two nations. In Ethiopia, the average level of depressive symptoms remained remarkably stable from pregnancy to the postpartum period; the scores did not go up or down significantly for the typical woman. In contrast, women in Guinea showed a different pattern. On average, their depression scores dropped noticeably after giving birth, suggesting that for many in Guinea, the immediate postpartum period brought a sense of relief or improvement compared to the stress of late pregnancy. However, this general improvement did not erase the disparity caused by violence. Even as the overall scores in Guinea fell, the women who had experienced abuse still had the highest levels of distress at both stages, maintaining a trajectory that was consistently worse than their peers.

Beyond the shadow of violence, the researchers found that other specific hardships also weighed heavily on a mother's mental state. In both countries, women who worried about having enough food to feed their families in the weeks before the second survey reported significantly higher depression scores. The loss of a baby, whether through stillbirth or early neonatal death, was associated with a dramatic spike in depressive symptoms, far higher than for women who had healthy births. Complications during pregnancy or childbirth also took a toll, as did having a pregnancy that was not planned or wanted. Conversely, having a strong network of social support acted as a buffer; women who felt they had adequate help from family and friends reported lower levels of depression. In Guinea specifically, women who attended four or more prenatal care visits had lower depression scores, hinting that regular contact with health services might offer a protective effect.

The study concludes that the link between violence and depression is not a temporary blip but a persistent reality for many mothers in these settings. The findings suggest that the emotional scars of abuse do not heal simply because a child has been born. Instead, the presence of violence creates a sustained elevation in distress that cuts across the entire perinatal period. The researchers emphasize that while the specific patterns of depression over time varied between Ethiopia and Guinea, the core message remained the same: violence is a major driver of poor mental health for mothers. They argue that to protect the well-being of mothers and their children, health services in these regions need to do more than just treat physical ailments. They must integrate routine checks for violence and mental health into standard prenatal and postnatal care, ensuring that women who are suffering in silence are identified and supported before the burden becomes too heavy to bear.
