Background: Pre-labor rupture of membrane (PROM) refers to a membrane rupture that occurs after the 28th week of pregnancy but before the start of labor. If not appropriately managed, it poses a significant risk to the health of the mother and fetus. However, information on the magnitude of PROM, contributing factors, and its perinatal outcomes was limited in Eastern Ethiopia. This study assessed the prevalence, predictors, and perinatal outcomes of PROM among pregnant women admitted to Hiwot Fana Comprehensive Specialized University Hospital (HFCSUH) in Eastern Ethiopia so as to guide specific preventive measures.
Methods: A hospital-based retrospective cross-sectional study was carried out from May 15 to June 14, 2022, and data were gathered by reviewing the chart records of 424 pregnant women who were admitted to maternity and labor wards in the previous two years, from January 1, 2019 to December 31, 2020. Records were chosen using a simple random sampling method. Mother’s socio-demographic traits, previous obstetric and gynecologic history, current pregnancy history, habit-related history (khat chewing), ultrasound findings, laboratory investigations, mode of delivery, maternal and perinatal outcomes were extracted from the maternal charts. Bi-variable and multivariable logistic regression analyses were performed to identify predictors of pre-labor membrane rupture. The association between the explanatory and outcome variables was expressed using an adjusted odds ratio with a 95% confidence interval.
Results: The prevalence of pre-labor membrane rupture was 16.27% with 95% CI: (13.05–20.11). Among 69 women who experienced pre-labor rupture of membrane, 50 (72.5%) of them had adverse perinatal outcomes. Of all 69 neonates 17 (24.64%) were delivered with low birth weight and 20 (29%) of them were born preterm. The overall perinatal mortality rate was 10.1% or 101 per 1,000 live births. History of abortion [AOR = 2.61; 95% CI (1.09, 6.24)], urinary tract infection [AOR = 2.59; 95% CI (1.23, 5.42)], antepartum hemorrhage [AOR = 3.35; 95% CI (1.38, 8.13)], and khat chewing (a leafy plant which contains psychoactive chemical) in the current pregnancy [AOR = 2.63; 95% CI (1.49, 4.63)] were all significantly associated with pre-labor rupture of membrane.
Conclusion: In this study, the magnitude of pre-labor membrane rupture was relatively high compared to the global rate. Prenatal risk identification and early detection of complications among mothers with a history of abortion, antepartum hemorrhage, urinary tract infection, and counseling on the effects of khat chewing during pregnancy are crucial to reduce the likelihood of pre-labor membrane rupture and its adverse perinatal outcome.
1 Introduction
Pre-labor rupture of membrane (PROM) is rupture of membranes prior to the onset of labor (1). Rupture of membrane that occurs before 37 completed weeks of gestation is referred to as preterm PROM while term PROM refers to a rupture of membrane that occurs after 37th completed weeks of gestation (2). Approximately 70% of PROM cases occur at term (3).
The magnitude of pre-labor membrane rupture (PROM) varies slightly around the globe and affects 3 to 15% of all pregnancies (3, 4). It is relatively higher in Africa. For instance, the prevalence of PROM was 13.8% in Uganda, and it ranges from 1.4 to 23.5% in Ethiopia (5–8).
Preterm prelabor rupture of membranes (PPROM) complicates up to 3% of pregnancies and term PROM complicates approximately 8% of pregnancies (2, 3). PROM has been associated with significant maternal and perinatal complications which include a high rate of Cesarean section (C/S), chorioamnionitis, abruption-placenta, cord prolapse, respiratory distress syndrome (RDS), birth asphyxia, low APGAR score (<7/10), preterm labor, low birth weight, admission to neonatal intensive care unit (NICU) and perinatal death (6, 8–10). Pre-labor membrane rupture (PROM) is responsible for 44% of perinatal morbidity and 7% of perinatal mortality (11). About one-third of preterm births, which are the main cause of newborn death, and 13–60% of intra-amniotic infections or chorioamnionitis in pregnant women are attributed to PROM (12).
Moreover, PROM has a wide range of negative effects, including maternal and neonatal mortality and morbidity, as well as national economic loss from prescription expenses, hospital stays, lost productivity, and healthcare expenditures (11, 12).
There is no recognized or clear cause for PROM. Nevertheless, numerous studies have demonstrated that socioeconomic/demographic factors (maternal age, level of education, income), behavioral factors such as smoking and khat chewing (a leafy plant with psycho active chemical content), trauma or falls, a history of abortion, a prior history of premature rupture of membranes, a history of cesarean section, abnormal vaginal discharge (vaginal discharge following genital tract infection including STI) and antepartum hemorrhage (APH) were certain factors related with the occurrence of PROM (5, 7, 10, 13–15). In addition, maternal medical conditions, multiple pregnancies, and malposition are common obstetric factors associated with the incidence of PROM (14, 16).
Different strategies have been set to reduce the adverse perinatal outcomes of PROM. A management protocol for selected obstetric cases including PROM were developed and use of prophylactic antibiotics for prolonged PROM (greater than 12 h) and steroid administration following pre-labor rupture of membranes remote from term were being implemented at all hospital levels (17). Despite all these efforts, feto-maternal complications related to PROM are still significant health problem in Ethiopia.
Assessing the modifiable or treatable risk factors of PROM is important to design strategies and interventions to prevent its complications and optimize pregnancy outcomes. Although prior studies tried to assess the magnitude and determinants of PROM at various levels and at certain times, the perinatal outcome of PROM and its predictors were not well studied in Ethiopia, specifically in this study area. Therefore, this study is intended to assess the prevalence, predictors and perinatal outcome of pre-labor rupture of membrane among pregnant women admitted to HFCSUH in Harar town, Eastern Ethiopia.
2 Methods and materials
2.1 Study setting and period
The study was done at the Hiwot Fana Comprehensive Specialized University Hospital (HFCSUH), which is situated in Harari region, Eastern Ethiopia, at a distance of 525 kilometers from Addis Ababa, the country’s capital. HFCSUH serves as a teaching hub and referral hospital and provides health care services for more than five million people in Eastern Ethiopia. It comprises four major departments (medical, surgery, pediatrics, and gynecology-obstetrics with 33, 42, 50, and 60 beds, respectively) and six minor departments (psychiatric, dental clinic, radiology unit, dermatology, ophthalmology, and chronic follow-up clinic visits). Additionally, it offers maternal health services to 5,800 pregnant women on average each year. This study was carried out from May 15, 2022 to June 14, 2022.
2.2 Study design and population
A retrospective cross-sectional study was undertaken among pregnant women admitted to Hiwot Fana Comprehensive Specialized University Hospital between January 1, 2019, and December 31, 2020. Randomly selected charts of pregnant women admitted to the maternity and labor ward with a gestational age of 28 weeks and above (calculated from the last normal menstrual period or an early ultrasound report obtained from medical records) were included in the study, whereas women’s charts with missing important data and pertinent variables (maternal conditions, obstetric/gynecologic history and perinatal outcomes) were excluded.
2.3 Sample size and sampling technique
Epi-calc statistical software was used to calculate the sample size with the double population proportion formula, taking into account variables that have a significant association with the outcome variable at p < 0.05, a two-sided confidence level of 95%, a margin of error of 5%, a power of 80%, and a ratio of exposed to unexposed of 1:1. Taking the previous history of urinary tract infection (UTI) as an exposure variable (outcomes among unexposed = 14.7% and outcomes among exposed = 26.74%) (5) and by adding a 10% non-response rate, the final required sample size was 429. All medical records of mothers admitted to maternity and labor ward between January 1, 2019, and December 31, 2020 were retrieved from the hospital’s archive room. Using admission-discharge register of labor and delivery logbooks as a sampling frame, all unique medical registration numbers of pregnant women’s chart or card were selected by simple random sampling until the desired sample size was achieved.
2.4 Data collection tool and procedure
A structured questionnaire and abstraction checklist that were initially developed in English were used to extract the data. The data collection instrument was crafted after revising pertinent literature (6–11, 15). The checklist includes socio-demographic characteristics, previous obstetric and gynecologic factors, current pregnancy-related factors, behavioral related factors (khat chewing), and perinatal outcomes. Prior to beginning the data collection, the supervisors and data collectors received a one-day training session. The data abstraction checklist and questionnaire were pretested on 5% of the sample size (n = 21) at another institution. Based on the findings of the pretest, adjustments and alterations were made to the tool. The validity of the tool was assessed using content validity and reliability was measured checking internal consistencies of the items (Cronbach’s α = 0.822).
Four Bachelor of Science midwives collected the data under the supervision of two Masters of Science nurses in maternity and neonatal nursing. Medical record numbers found in the labor and delivery ward registry were used to retrieve the necessary records. After that, the patient’s card was retrieved from the hospital’s archive room. All maternal records located in the admission record format and charts of Child Health and Mortality Prevention Surveillance (CHAMPS) were scrutinized to gather relevant data regarding the mother’s socio-demographic traits, previous obstetric and gynecologic history, current pregnancy history, habit-related history (khat chewing), ultrasound findings, laboratory investigations, mode of delivery and maternal and perinatal outcomes. Every day, the acquired data were reviewed for precision and comprehensiveness.
2.5 Operational definitions
2.5.1 Pre-labor rupture of membranes (PROM)
A rupture of membrane after 28 weeks of pregnancy (after fetal viability) and before the onset of labor (4, 5). The diagnosis of PROM was made if a woman had a history of leaking or gushing watery vaginal fluid without a uterine contraction, visualization of fluid pooling in the fornix or from the cervix with speculum examination and by using a basic pH test of vaginal fluid or ferning of dried vaginal fluid identified under microscopic evaluation refined/documented by physician/professionals (5, 17).
A perinatal outcome is an outcome that can happen from the 28th week of gestation to the first week of the postpartum period. It can be adverse (unfavorable) perinatal outcomes or favorable perinatal outcomes (8, 9).
2.5.2 Adverse perinatal outcome
Presence of either of the following: preterm birth, perinatal death (stillbirth and immediate newborn death), low birth weight, birth asphyxia, respiratory distress syndrome (RDS), meconium aspiration syndrome (MAS), low APGAR score (<7/10), and admission to the NICU (neonatal intensive care unit) (6, 8, 9).
2.5.3 Stillbirth
A newborn that shows no signs of life at or beyond 28 weeks of pregnancy (6, 8).
2.5.4 Low birth weight
A newborn weighing less than 2,500 g at birth (9, 18).
2.5.5 Preterm birth
When a baby is born alive before 37 full weeks of pregnancy but after 28 weeks of pregnancy (8, 18).
2.5.6 Perinatal mortality
The sum total of stillbirths, fetal deaths in pregnancies longer than 28 weeks, and early neonatal deaths that occur within the first few weeks of life (7, 9, 10).
2.6 Data processing and analysis
EpiData version 3.1 was used to code, clean, and double-enter the data before they were exported to SPSS version 26 for analysis. Descriptive data analysis was computed to generate proportions, frequencies and mean. The pre-labor membrane rupture was the outcome variable, and it was coded as ‘1’ for diagnosed PROM and ‘0’ for no PROM. To determine the predictors of PROM, bi-variable and multivariable logistic regression analyses were carried out. Explanatory variables with a p-value of less than 0.25 in the bi-variable analysis were regarded as candidates for the multi-variable logistic regression analysis. Model fitness was evaluated using the Hosmer-Lemeshow test (0.910). An adjusted odds ratio (AOR) with 95% confidence interval was used to describe the association between the independent variables and outcome variable. A p-value less than 0.05 were taken as significant in the final model.

3.6 Predictors of PROM
In bi-variable analysis, age, abortion history, previous preterm birth, previous PROM, previous C/S, antenatal care follow-up, UTI, pregnancy-induced hypertension, antepartum hemorrhage (APH), and khat chewing were associated with PROM at p < 0.25. After adjusting for confounding variables, the history of abortion, UTI in the current pregnancy, antepartum hemorrhage, and khat chewing during the current pregnancy remained statistically significant in the multivariable analysis.
Those women with an abortion history had 2.6 times greater odds of PROM [AOR = 2.61; 95% CI (1.09–6.24)] when compared to women without an abortion history. Moreover, women who experienced a UTI during the current pregnancy had a 2.6-fold [AOR = 2.59; 95% CI (1.23–5.42)] increased risk of developing PROM compared to women who did not.
Additionally, those women with APH were about 3.4 times more likely [AOR = 3.35; 95% CI (1.38–8.13)] to have PROM when compared to women who did not have APH during the present pregnancy. Furthermore, the risks of developing PROM were 2.6 times greater for those women who chewed khat throughout the present pregnancy when compared to those women who did not [AOR = 2.63; 95% CI (1.49–4.63)] (Table 5).

4 Discussion
Pre-labor rupture of membrane (PROM) is one of the significant obstetric problems that lead to morbidity and death among women and their newborns. This study assessed the prevalence, predictors, and perinatal outcomes of pre-labor membrane rupture among pregnant women admitted to Hiwot Fana Comprehensive Specialized University Hospital in Harar town, Eastern Ethiopia.
In this study, the overall prevalence of PROM was 16.3% (95% CI, 13.05–20.11). This study finding is consistent with the findings of studies conducted in Debre Tabor (13.7%) (5), Jimma (14.6%) (8), Uganda (13.8%) (19) and China (19.53%) (20). However, this result was higher than those of studies conducted in Brazil (3.1%) (13) and Tikur Anbessa Hospital in Ethiopia (1.4%) (6). The higher prevalence of PROM in our study could be attributed to inclusion criteria, as our study included all PROM diagnoses, whereas other studies only included preterm PROM. Furthermore, because the study site is a referral hospital, more severe and complicated cases of PROM were referred to and admitted to this hospital, thus increasing the prevalence of PROM.
This finding, however, was lower than those of the studies conducted in India (27.9%) (9), and Harar (23.5%), Ethiopia (7). This disparity could be attributed to the high sample size and inclusion of more than one facility, whereas our study was conducted only at one institution.
In this study, the perinatal mortality rate was 101/1000 live births (10.1%). This finding was consistent with that of Tikur Anbessa specialized teaching hospital (10.7%) (6), but higher than the study finding from Bangladesh 7% (11). This discrepancy might be due to low ANC follow-up among our study participants, where more than 27% of the women have no ANC follow-up. Another possible explanation could be due to our study facility was a referral hospital and most of the cases were referred from remote areas after they developed complications.
This study found that women with previous experiences of abortion were more prone to suffer pre-labor rupture of membranes than women with no experience of abortion. This result is congruent with research conducted in Uganda (19), Mekele (10), and a public hospital in southern Ethiopia (21). The possible reason for this might be the abortion technique, particularly dilation and curettage, may impair cervical and uterine flexibility, resulting in uterine scarring and cervical insufficiency, which results to pre-labor membrane rupture. Another possible explanation could be due to the fact that abortion can result in cervical incompetence. During abortion, mechanical dilation results in cervical trauma and may increase the risk of cervical incompetency. This might predispose membrane to trauma and rupture through effacement and dilation of the cervix (14, 22). Furthermore, the women with unsafe abortion are at greater risk to suffer from intra-amniotic and intrapartum infections, which may result in PROM (13, 23). Preventing unsafe abortion and providing high-quality post-abortion care (PAC) can help to reduce the adverse health consequences of unsafe abortion. Screening and follow-up for a mother with an abortion history are also essential to decrease the risk of PROM and its adverse perinatal outcome.
Moreover, women having a history of antepartum hemorrhage (APH) in the present pregnancy were more likely to have pre-labor membrane rupture than their counterparts. This result was consistent with the findings of research conducted at Debretabor General Hospital (5). The possible reason for this could be the formation of thrombin as a result of decidual hemorrhage may trigger the production of inflammatory cytokines and proteases, resulting in tissue necrosis, degradation of the extracellular matrix, and membrane rupture (24).
Furthermore, this study found that women who had urinary tract infections (UTIs) during pregnancy were at greater risk to have premature membrane rupture. This is consistent with study findings in rural Uganda (19) and Debretabor (5). This link could be explained by the fact that UTIs are potential reservoirs for bacteria that enter the vagina and go up through the cervical canal to the membranes, causing localized irritation. The bacteria produce a variety of proteolytic enzymes, including collagenase and gelatinase, which can cause local membrane weakening (25). Inflammatory mediators, like prostaglandins, cytokines, and proteinases in the local tissue also have a role in disrupting fetal membrane integrity and inducing uterine contractility. The generation of matrix-degrading enzymes and TNFs (tumor necrosis factors) also play a role in occurrence of PROM processes. Then, due to localized inflammation, occult contractions with increased pressure at the internal cervical os will occur, leading to PROM (24). As a result, early detection and treatment of UTIs during pregnancy are critical to reduce the risk of PROM and associated consequences.
This study also found that khat chewing is a strong predictor of premature membrane rupture. This is backed by another study finding in Eastern Ethiopia (7). Evidences showed that khat chewing practices have a negative impact on periodontal oral health (26).
The relationship between periodontal disease and PROM may be due to a probable transfer of peri-pathogenic bacteria to the placenta and amniotic fluid, as well as a systemic response to this chronic inflammatory condition (27). The possibility that chewing khat cultivated with chemical pesticides may cause significant unfavorable perinatal outcomes in khat users warrants further research.
Though pregnancy induced hypertension (PIH) and history of PROM were not significantly associated with PROM in our study, it is difficult to deny their impact on the occurrence of PROM during subsequent pregnancies. Khat chewing may increase the risk of hypertension among pregnant women which in turn may result in PIH predisposing the women for APH (particularly abruption-placenta) which is associated with PROM in our study. Hence further research is required to investigate the impact of Khat chewing on PIH and how PIH leads to APH.
4.1 Strength and limitations of the study
The CHAMPS (Child Health and Mortality Prevention Surveillance) evaluation or admission format sheet, as well as medical record cards, were utilized in this study. Furthermore, this study included other characteristics, such as khat chewing that had not been addressed in earlier investigations. This study also attempted to evaluate adverse perinatal outcomes related to PROM, which may provide an ideal option to anticipate PROM outcomes and prevent its complications. Because this study was conducted in a single referral center, our findings may not be applicable to people visiting lower-level facilities. Furthermore, retrospective data are susceptible to information bias. Moreover, because the data are cross-sectional, it is impossible to draw conclusions about the cause-and-effect relationship between the outcome and associated variables.
5 Conclusion
In this study, the magnitude of PROM was relatively high in comparison to the global rate. A history of abortion, UTI, antepartum hemorrhage, and khat chewing were all found to be risk factors for PROM. Prenatal risk identification and early detection of complications among mothers with a history of abortion and antepartum hemorrhage in the current pregnancy, screening, and treatment of UTI, and raising community awareness about the risk of khat chewing are required to minimize the occurrence of PROM and its adverse perinatal outcomes.
