Prevalence and Determinants of Birth-Related Perineal Tears Among Women with Vaginal Deliveries at a Tertiary Public Hospital in Northern Uganda: A Retrospective Cross-Sectional Study
This retrospective cross-sectional study of 390 women at Lira Regional Referral Hospital in Northern Uganda found a 30.26% prevalence of birth-related perineal tears, identifying nulliparity and prolonged labor stages as significant independent predictors.

Childbirth is a profound biological event, yet it carries an inherent risk of physical injury that often goes unspoken in public health discussions. When a baby is born through the vaginal canal, the tissues of the perineum—the area between the vaginal opening and the anus—must stretch significantly to allow the baby to pass. Sometimes, this stretching exceeds the limits of the skin and muscle, resulting in a tear. These injuries range from minor cuts that heal quickly to more severe damage involving the muscles that control bowel movements. While many women recover without long-term issues, these tears can lead to pain, infection, and lasting difficulties with daily life. Understanding why these tears happen is crucial for doctors and midwives, as it allows them to anticipate risks and protect mothers during the most vulnerable moments of delivery. In many parts of the world, particularly in regions with fewer medical resources, the true scale of this problem remains unclear, making it difficult to design effective care strategies.
In a recent study conducted at a major public hospital in Northern Uganda, researchers set out to uncover the specific patterns of these injuries. They focused on the Lira Regional Referral Hospital, a facility that serves a vast population of approximately 2.5 million people across the Lango sub-region. The team looked back at the medical records of 390 women who had given birth vaginally at the hospital between October and December 2024. By carefully reviewing these files, they aimed to count how many women experienced a tear and to identify the specific circumstances during labor that made such injuries more likely. The researchers were particularly interested in factors like whether it was a woman's first baby, how long the labor lasted, and the skill level of the person assisting the birth.
The investigation revealed that birth-related tears are a common occurrence in this setting. Out of the 390 women studied, 118 sustained some form of perineal tear, meaning that roughly one in three women who delivered vaginally experienced this injury. This finding highlights that perineal trauma is a significant source of maternal health challenges in the region. The study did not just count the injuries; it sought to understand the "why" behind them. The analysis pointed to three main factors that independently increased the likelihood of a tear. First, women who were giving birth for the first time were at a higher risk. Second, women whose active labor lasted eight hours or longer were more likely to tear. Third, the risk increased if the second stage of labor—the period from full dilation to the actual birth of the baby—lasted longer than 60 minutes.
Interestingly, the study found that other common assumptions did not hold up as strong predictors in this specific group. For instance, the age of the mother, her education level, or the weight of the baby did not show a statistically significant link to the occurrence of tears once the other factors were accounted for. Similarly, whether a skilled or unskilled attendant was present did not change the risk in the data collected. The researchers emphasized that the length of labor and the experience of being a first-time mother were the most consistent signals of danger. This suggests that the physical stress of a long labor, combined with the lack of prior stretching of the tissues in first-time mothers, creates a perfect storm for injury.
The implications of these findings are practical and immediate for the hospital and similar facilities. The authors suggest that by paying closer attention to the duration of labor, medical staff can identify women who are at higher risk before an injury occurs. For first-time mothers, or for any woman whose labor drags on beyond the typical windows, extra vigilance and specific protective techniques could make a difference. The study also noted that while the hospital sees a high volume of complex cases, the records sometimes lacked details on how severe the tears were, which limits the ability to compare the severity of injuries with other studies. Despite this limitation, the data provides a clear map of the risks.
Ultimately, this research underscores that preventing these injuries is not just about having a doctor present, but about how labor is managed over time. The findings support the idea that careful monitoring of labor progress, combined with evidence-based techniques to support the perineum during delivery, could reduce the number of women who leave the hospital with preventable injuries. By focusing on the specific moments when the risk is highest—the first birth and the prolonged stages of labor—healthcare providers in Northern Uganda and similar resource-limited settings can better protect the physical well-being of mothers during childbirth.
