Abstract
Objective:
The study aimed to assess the prevalence of obstructed labor and associated factors among women delivered at public hospitals in Southern Ethiopia.
Methods:
Institution-based cross-sectional study was employed among 704 systematically selected postnatal women. The data were collected by the structured and pre-tested interviewer-administered questionnaire and analyzed by Statistical Package for Social Science version 20. Multivariable logistic regression with a 95% confidence level was used to determine the associated factors. Statistical significance was declared at
Result:
The prevalence of obstructed labor was 15.8% (95% confidence interval: 13.1–18.5). Age (adjusted odds ratio = 5.23, 95% confidence interval: 2.98–11.12), antenatal care follow-up (adjusted odds ratio = 1.8, 95% confidence interval: 1.10–3.39), duration of labor (adjusted odds ratio = 4.41, 95% confidence interval: 2.56–7.67), and experiencing complications (adjusted odds ratio = 4.21, 95% confidence interval: 2.63–6.98) were significantly associated with obstructed labor.
Conclusion:
The study revealed that one-sixth of women experienced obstructed labor. Regional health sectors and non-governmental organizations need to collaborate with healthcare providers in providing improved maternal health services with special emphasis on teenage women with optimum and proper follow-up throughout the pregnancy, by early identifying complications during labor and delivery to manage the problem early.
Introduction
Worldwide maternal mortality is the leading cause of death among females aged 15–49 years, an estimated 295,000 maternal deaths were reported in 2017; of this, 94% (277,300) of maternal deaths occur in developing countries and more than half of these deaths occurred in sub-Saharan Africa accounting 196,000 maternal death. 1 The approximate lifetime risk of maternal death in developed countries was 1 in 5400 as compared to 1 in 45 in low-income countries. 1
One of the main causes of maternal, and perinatal morbidity and mortality is delayed and neglected management of obstructed labor. 2 Globally, obstructed labor occurs in an estimated 5% of pregnancies and accounts for an estimated 9% of maternal deaths 3 with a higher incidence in developing areas, which varies from region to region, with 4.1% of all maternal deaths in Africa, 9.4% in Asia, and 13.4% in Latin America and the Caribbean. 4 Maternal mortality from obstructed labor is largely the result of hemorrhage due to ruptured uterus and puerperal infection, whereas prenatal mortality is mainly due to asphyxia. 5 The most frequent cause of obstructed labor is a cephalo-pelvic disproportion—a mismatch between the fetal head and the mother’s pelvic brim, 6 followed by mal-presentation or malposition of the fetus 6 and it can be caused by locked twins or pelvic tumors in rare situations. 7
Women in most sub-Saharan African countries are traditionally expected to give birth at home, and if complications arise, healthcare services are frequently delayed. 8 This may be due to three delays: delay in deciding to seek medical care, delay in reaching the facility, or delay in the offering of medical services while the patients are already in the facility. Inadequately developed healthcare systems including poor infrastructure, poor transportation, and poor obstetrics care are also major contributors to obstructed labor. 9
Ethiopia is one of the sub-Saharan African countries with the highest maternal death ratio, 871 per 100,000 live births in 2000 and now declined to 401 deaths per 100,000 live births in 2017, 10 and also is one of the six countries that contribute about 50% of global maternal deaths. 11 The major causes of maternal deaths in Ethiopia are similar to most developing countries. The proportion of maternal deaths in Ethiopia is attributed to various causes’ changes from year to year. Overall the case fatality rates of the ruptured uterus/obstructed labor and preeclampsia/eclampsia indicate an increasing trend while that of abortion remains stable. Obstructed labor accounts for 36% of maternal deaths in Ethiopia, according to these figures. 9 A systematic review and meta-analysis done in Ethiopia indicated that the prevalence of obstructed labor was 11.79%. 12 Another systemic review and meta-analysis showed that 14.4% pooled prevalence of maternal death incidence, 41.18% pooled prevalence of uterine rupture, 30.5% pooled prevalence of maternal near-miss, and 26.4% pooled prevalence of perinatal death in mothers faced obstructed labor. 13 Other complications such as obstetric fistula, hysterectomy, bladder injury, sepsis, postpartum hemorrhage, perinatal asphyxia, and stillbirth were reported by systematic review and meta-analysis in Ethiopia. 13
To bring a remarkable change to maternal mortality rate (MMR), countries targeted a new strategy called Sustainable Development Goals (SDGs) which targeted in reducing global maternal mortality to less than 70 deaths per 100,000 live births, and no country should have exceeded MMR of 140 maternal deaths per 100,000 live birth by 2030. 14 Ethiopia was also striving to end preventable maternal mortality, including those caused by obstructed labor, and it accounted for 19.1% of maternal death in Ethiopia.15,16
Even though obstructed labor in Ethiopia seems to be a common cause of maternal and prenatal morbidity and mortality, there is a dearth of evidence to increase the knowledge base for more successful intervention against obstructed labor, and understanding the factors associated with it is critical to take prompt action to prevent maternal and neonatal morbidity and mortality. Although the prevalence of obstructed labor remains high and a serious public health issue. 12 Most of the studies previously done were at a single public hospital,17–23 and even though there was an attempt to determine the prevalence of obstructed labor with a small sample size (165) at a similar study area, 22 it was not adequate. Thus, this study aimed to assess the prevalence and associated factors of obstructed labor among women delivered in public hospitals in southern Ethiopia.
Methods
Study area and period
This study was conducted in the western part of the Southern Nation, Nationalities, and People’s Region (SNNPR) from March 1 to 30, 2020. Hawasa was the capital city of SNNPR, which was located 284.8 km away from Addis Ababa, the center of Ethiopia, in the Southwest direction. 24 The study area includes four zones (Kaffa zone, Sheka zone, Bench-Sheko zone, and Debub mihrab Omo zone) with a total population of 1,355,422, 51% are female and 49% are male (population projection of Zonal Health Department). 25 It has 5 hospitals (two General, two primary hospitals, and one teaching hospital) and 96 health centers, all health facilities give delivery services; two Universities, one Health Sciences College, and 1 teaching college.24,26
Study design and population
Institution-based cross-sectional study design was employed. The source population was all women who gave birth in public hospitals in the western part of the SNNP regional state, Ethiopia. Mothers who gave birth in selected public hospitals during the actual data collection period were included in the study. Mothers who were severely ill and unable to communicate during the data collection period were excluded.
Sample size determination ad sampling procedures
The sample size was calculated using a single population proportion formula with the assumptions of
The total sample size was proportionally allocated to each selected health facility and became 199, 169, 155, 111, and 104 for Mizan Tepi University Hospital, Gebretsadik Shawo hospital (GSGH), Tepi General Hospital, Bachuma Primary Hospital, and Mizan Primary Hospital, respectively. Then eligible mothers in each facility were selected by a systematic random sampling technique with
Data collection method and procedure
The data were collected by interviewer-administered structured questionnaire and review of secondary data. The questionnaire was developed based on the Ethiopian Demographic Health Survey data collection tool and other relevant works of literature.17,19 The questionnaire contains two parts: the sociodemographic characteristics, health facility-related characteristics, and obstetric characteristics. Data collection was carried out by five BSc midwifery as data collectors while two MSc Midwifery were nominated as supervisors for 1 month. The questionnaires were initially prepared in English and then translated into Amharic and then back into English by a linguistic teacher to check their consistency. Cronbach’s alpha test was used to determine a tool’s reliability (0.83). A pilot test was done on 5% of the sample size, and based on its result ambiguous question was refined, and misunderstood question was modified. All information was collected from mothers who give birth in the hospital after their vital sign stability was confirmed and before their discharge. Maternal delivery records were reviewed at the same time before they left the health facilities. The diagnosis of obstructed labor is made by a physician or gynecology resident working in the hospital. Data collectors checked the cause by reviewing the client records.

Operational definition
Data quality control
To ensure the quality of the data, a structured and pretested questionnaire was used. Five percent of the questionnaires were pretested at the Tercha Primary Hospital (found in the nearby zone) before the actual data collection period. Then, further clarification and conceptuality of instruments were checked, data collectors familiarize themselves with the instrument, and the time needed was estimated. Based on the pretest result, ambiguous and unclear questions were modified accordingly. Two days of intensive training about instruments, ways of data collection, ethical issues, and the aims of the study were provided for data collectors and supervisors. To keep completeness and consistency, data collectors were closely supervised before and during the data collection process. The data were double-entered into Epi data version 4.2.0 by two different individuals.
Data processing and analysis
Data were checked for completeness, coded, and entered into Epi data version 4.2.0 software, and analyzed by SPSS version 20. Descriptive summaries such as frequency, prevalence, cross tabs, and graphical presentation were used. The association between independent and outcome variables (obstructed labor) was analyzed using bivariate and multivariable logistic regression. It was checked by crude odds ratio and 95% confidence level. The variables with

Sociodemographic characteristics
Among 738 study participants, 704 women were participated in the study which made response rate 95.4%. The mean (±SD) age of the respondents was 28.5 (±5.8) and ranged from 18 to 45 years. Less than two-thirds of 451 (64.1%) of them were in the age group of 20–30 years. The majority, 587 (83.4%), of study participants were married. The mean monthly income of respondents was 1988.4 (±1817.7 SD) Ethiopian birr and 411(58.4%) of them had a monthly income of <2000 Ethiopian Birr (Table 1).

Obstetric characteristics
Of the total study participants, 630 (89.5%) of them had 1–4 live births. About 595(84.5%) of them had ANC follow-up while 307(51.6%) of them had started ANC follow-up in the second trimester of their pregnancy. In all, 608 (86.4%) participants’ labor took 12–24 hours, and 105(14.9%) of the respondents were delivered through the cesarean section while almost one out of five (20.7%) of participants of the study encountered labor and delivery complications, the most common complication was postpartum hemorrhage 78 (53.4%) (Table 3).

Factors associated with obstructed labor
To identify associated factors with obstructed labor, nine variables (age, have their source of income, parity, ANC follow-up, institutional delivery, complication during labor and delivery, birth weight, gestational age, and duration of labor) that had
The odds of obstructed labor were higher among women whose age was <20 years (adjusted odds ratio (AOR) = 5.23, 95% CI (2.98, 11.12)) as compared to their counterparts. Women who had no ANC follow-up were 1.8 times (AOR = 1.8 (1.10, 3.39)) greater likelihood of having obstructed labor than those who had at least one ANC follow-up. Women who were laboring for ⩾24 hours were 4.41 times (AOR = 4.41, 95% CI (2.56, 7.67)) more likely to experience obstructed labor than women whose labor persists <24 hours of duration. Those women who experienced any complications during their labor and delivery were 4.21 times (AOR = 4.21, 95% CI (2.63, 6.98)) had a greater likelihood of experiencing obstructed labor than their counterparts (Table 4).

Discussion
Globally, up to 15% of pregnancies might develop a risk of complications and will be threatening the life of the mother and/ or newborn. 27 Obstructed labor is a risky pregnancy complication, which was rare in developed countries, but is still one of the leading causes of maternal and prenatal mortality in developing countries. 28 Obstructed labor contributed 4.1% (range: 0–10.3%) to all maternal deaths in Africa. 29
In this study, 15.8% of women experienced obstructed labor. This finding was in line with other institution-based studies conducted in Ethiopia: Mizan Tepi University Teaching Hospital (15.3%),

This might be due to the difference in the study setting, sample size, socioeconomic, and the difference in the time duration of the studies. For instance, a study conducted in 2015 in Mizan Aman General Hospital, Southwest Ethiopia had a small sample size (
On the other hand, the prevalence of obstructed labor reported in this study is lower than the study conducted at Public Hospitals of Western Hararghe Zone, Oromia, Ethiopia in 2018 (34.3%), 33 Mojo Town, Oromia (22%), 34 and 20.5% prevalence of obstructed labor was reported in Nigeria. 35 The possible difference for this might be an improved healthcare system, proper care during pregnancy and delivery, and improved ANC follow-up in recent years than ever before. In addition to that improved referral linkage between the three-tier system of health care, primary levels of care (health post, health centers, and primary hospitals), the secondary level of care (general hospitals), and tertiary level of health care (specialized hospitals) than ever might be another reason.
Women below 20 years had higher odds to face obstructed labor. This is consistent with findings reported from Ethiopia: a hospital-based cross-sectional study conducted in Halab Kulito Primary Hospital in 2015, 17 Gimbi General hospital in 2019, 21 and Southwestern Uganda. 32 This implies that pregnancy and related labor and delivery in teenagers are very risky for both maternal and fetal well-being secondary to her body not being well matured.
In this study, women who had no ANC follow-up had greater odds of having obstructed labor than those who had ANC follow-up. A similar finding was reported by another research in Southern Ethiopia. 17 This could be because not having ANC during pregnancy may decrease women’s knowledge about risk factors of obstructed labor like multiple pregnancies, a big baby, and fetal anomalies. In addition, women who did not have ANC were prone to home delivery, have poor awareness about birth preparedness and complication readiness plan, and danger signs of pregnancy which might increase the risk of obstructed labor. 3
Duration of labor that persists ⩾24 hours were significantly associated with experiencing obstructed labor. This is in line with a study conducted in Adigrat Zonal Hospital, Tigray Region, Ethiopia reported that obstructed labor was highly prevalent among women who are in labor for a long time, 36 Metu Referal Hospital, Ilu Ababora Zone, Southwest Ethiopia, 18 Adama Hospital Medical College, 19 Mojo Town, Oromia, 34 Hawasa Town 37 and also abroad study reported that prolonged labor and obstructed labor were significantly associated.7,38 Therefore, proper follow-up of danger signs of obstructed labor to women in labor and delivery and appropriate utilization of partograph to follow labor progress will help reduce the occurrence of obstructed labor which, in turn, decreases maternal mortality. 39 Later, this will help in achieving SDG targeting the reduction of maternal morbidity and mortality related to labor and delivery. 40
Those women who experienced any complications during labor and delivery were more likely to encounter obstructed labor. This finding is consistent with the study finding done in Halaba Kulito primary Hospital, Southern Ethiopia, 17 Mizan-Aman General Hospital, Ethiopia, 22 Adama Hospital Medical College, Ethiopia, 19 and in Southwestern Uganda. 32 This might be due to complications like mal-presentation, cephalo-pelvic disproportion, and malposition left unidentified and managed early, they were at high risk for obstructed labor since their diameter was not competent to pass through the pelvic bone. Therefore, to avoid related problems and enhance maternal and fetal outcomes, early detection and prompt intervention are crucial.
If neglected in the early stages, obstructed labor can result in serious or life-threatening complications, including the death of the mother and/or the unborn child. Therefore, special attention coupled with optimum and timely care by advancing ANC follow-up, and easy access to labor and delivery service for those pregnant women would minimize maternal complications, so that it is possible to prevent morbidity and mortality secondary to obstructed labor.
This study utilized both primary and secondary data, all zonal public hospitals (multicenter study) were incorporated and a relatively large sample size was used. However, this study was Institution-based and it may not represent the proportion of obstructed labor in the community since many rural populations limited health service utilization.
Conclusion
The prevalence of obstructed labor was higher than in developed and even some developing countries. The main causes were cephalo-pelvic disproportion, malposition, and mal-presentation. Most obstructed labor was managed by the caesarian section. Maternal age, ANC follow-up, duration of labor ⩾ 24 hours, and any complications experienced during labor and delivery were significantly associated with obstructed labor. Regional and Zonal district health sectors and non-governmental organizations should work in collaboration with healthcare providers in providing improved maternal health services with special emphasis on teenage women with optimum and proper follow-up throughout the pregnancy, by early identifying complications during labor and delivery and properly managing them.
