The Epidemiology of Induction of Labor among Women Aged 15 - 49 Who Delivered at Shaafi Hospital in Hodon District, Mogadishu Somalia 2020 ()
1. Background
Induction of labor refers to artificial stimulation of uterine contractions before the true onset of spontaneous labor in order to achieve vaginal delivery; induction Labor is typically induced by using one of the following methods: Cervical ripening agents, artificial rupture of membranes, and uterine stimulation with oxytocin [1].
Induction of labor with the goal of achieving vaginal delivery prior to spontaneous onset of labor is recommended when the benefits of delivery out-weight the risk of continuing the pregnancy [2].
The World Health Organization (WHO) recommends induction is to be performed with a clear medical indication and when expected benefits outweigh potential harms [3].
The most common indication for induction of labor is prolonged pregnancy. The aim is to improve the health outcomes of the mother and/or baby. Induction of labor beyond 41 weeks’ gestation has been shown to reduce rates of caesarean section, operative vaginal delivery, meconium staining and macrosomia (birth weight > 4000 g) and risk of fetal and neonatal death [4].
Worldwide, the prevalence of labor induction varies greatly between countries and even between different regions of the same country. In general, however, it is higher in developed countries (at around 20%) than in developing countries [5].
In the United States of America and the United Kingdom, about 23% of all deliveries are by induction of labor [6] [7] while 11.4% was reported in Latin America [8]. Rate of induction labor are low in some Africa region evidenced by only 3% of women had an induction of labor in Nigeria hospitals [9].
There are a number of complications of pregnancy that confer significant ongoing risk to the mother or fetus (e.g., preeclampsia; preterm premature rupture of the membranes (PPROM); intrauterine growth restriction (IUGR); and post term pregnancy). For these conditions, induction of labor (IOL) is often the principal medical intervention utilized to decrease both maternal and neonatal morbidity and mortality [10].
In Somalia, the national rate of induction of labor (IOL) is not known.
2. Problem Statement
Worldwide, the prevalence of labor induction varies greatly between countries and even between different regions of the same country. In general, however, it is higher in developed countries (at around 20%) than in developing countries. [5]. the study conducted in Latin America showed that the average induction of labor was 11.4% (lower, 5.1% in Peru and higher, 20.1% in Cuba). Whereas the factors like: Age ≥ 35 years, being unmarried, Parity, PROM, hypertension during pregnancy and number of ANC visit ≥ 4 were significantly associated to the rate of induction of labor [8].
In Nigeria, the magnitude of induction of labor was 6.5% and in D.R. Congo which was 3.2% [11]. Their research conducted in Ethiopia, Addis Ababa two teaching hospitals magnitude of induction of labor was 4% [12]. Induction of labor is one of the most common procedure in obstetrics and one of the fastest growing procedures in the world mainly in developed countries. The reason why it rises is unclear but there are some assumptions, like a growing use of labor induction for post term pregnancies, an increasing trend towards elective induction of labor and induction with mothers’ request (elective induction) [13]. Furthermore, many pregnant women around the world to have undergone labor induction to deliver their babies this is factors generally included; gestational age of 41 completed weeks or more, pre-labor rupture of amniotic membranes, hypertensive disorders, maternal medical complications, fetal death, fetal growth restriction, chorioamnionitis, multiple pregnancy, vaginal bleeding and other complications etc. [5]. Although induction of labor is a daily practice at public and private health hospitals in Somalia; the national rate of induction of labor (IOL) is not known. However, the maternal mortality rate in Somalia in 2016 was 732 maternal deaths per 100,000 live births, which is among the highest in the world. Accordingly, the lifetime risk of maternal death in Somalia is among the worlds highest, 1 in 22, exceeded by only Chad and Sierra Leone [14]. Since Somalia demographic health survey report 2020 neither National Health information system (NHIS) indicators do not include information on induction of labor and In Somalia The civil registration and vital statistics system (CRVS) including mamaternal death Surveillance and Responseis lacking knowing the epidemiology of inductions of labor is crucial. A total of 370 women were derived in shaafi hospital from October 2019 to 31 March 2020. While 40 were inducted deliveries, 206 were spontaneous vaginal deliveries and 124 were cesarean section deliveries respectively. Therefore, the epidemiology of induction of labor among women aged 15 - 49 who delivered at Shaafi hospital in Hodon district, Mogadishu Somalia 2020.

housewife, followed by 4 (13%) were employed. A total of 15 (50%) there income was in between $300 - $400 monthly and followed 9 (30%) there income per month was above $500.
Table 2 showed that 12 (40%) had undergone induction once time previously, followed by 8 (27%) had undergone induction previously two times, while (20%) had undergone previously three times, 4 (13%) more than four times. 21 (70%) were delivered Spontaneous Vagina delivery (SVD), 6 (20%) were Cesarean section
(CS) and 3 (10%) instrumental vaginal delivery. In Table 2, 22 (73%) gave a safe birth (a life newborn) through induced labor one time, followed by 2 (7%) two times, 6 (20%) gave birth (dead newborn) through induced labor one time with their previous deliveries. A total of (60%) were delivered in public hospitals, followed by (23%) were delivered in private hospitals and 5 (17%) home delivery. In Table 2, a total of respondents 27 (90%) were 10 months (42 Weeks) of gestational period while having induced labor, while 3 (10%) were between 7 - 9 months (25 - 36 weeks). the reason of having induction of labor among study respondent about 2 (27 (90%) responded post term, followed by 2 (7%) were Intrauterine fetal death (IUFD), while only 1 (3%) were Pregnancy induced hypertension (PIH).
In Table 2, A total of 9 (30%) were started their ANC visit during the period between 4 - 6 months (13 - 24 Weeks), followed by 3 (20%) who were started their ANC visit in between 7 - 9 months (25 - 36 weeks). While most proportion about 17 (57%) had no previous ANC visit.
In Table 2, total of 23 (77%) were often take their daily sleep sometimes, while 4 (13%) had daily sleep in fixed time.
In Table 2, total of 22 (73%) had household chores sometimes, while 6 (20%) had household chores mostly.
In Table 2, total of 26 (87%) had daily meal intake twice during their previous pregnancies, while 3 (10%) had three times a day.
Table 3 showed When Women’s previous frequencies induced labor were cross tabulated to their reasons of induction showed that 26 (87%) women who previously had induced one were due to Post term (Post-mature), followed by 2 (7%) of women who previously had induced two times were due to Intrauterine fetal death (IUFD). Significant difference was strongly observed (P = 0.00).
Table 4 illustrated Women’s previous frequencies of induced labor were cross tabulated to their ANC visit showed that 13 (43%) of women who had previously induced once time was not visiting ANC during their previous pregnancies.

Followed by 3 (10%) of women who had previously induced two times was not visiting ANC during their previous pregnancies. Significant difference was not observed (P < 0.171)
Table 5 illustrated Women’s previous frequencies of induced labor were cross tabulated to their daily meal intake showed that 25 (83%) of women who had previously induced once time were taking their daily meal twice a day during previous pregnancies. While 1 (3%) of women who had previously induced three times were taking their daily meal twice a day during their previous pregnancies. significant difference was strongly observed (P < 0.001).
6. Discussion and Recommendation
This study aimed at to assess the epidemiology of induction of labor among women aged 15 - 49 who delivered at Shaafi hospital in Hodon district, Mogadishu Somalia 2020 during the period of the study from May-July 2020.
In Table 1, the study revealed that 18 (60%) were aged between 25 - 34 years, followed by 8 (27%) were aged between 25 - 34 yrs. While only 4 (8%) were between aged 35 - 44 yrs. 21 (70%) were married, 5 (17%) were divorced, 4 (13%) were windowed. While (37%) were primary level, while 7 (23%) were illiterate. The results explained that 21 (70%) were housewife, followed by 4 (13%) were employed, 15 (50%) there income was in between $300 - $400 monthly, followed 9 (30%) reported that their household income per month was above $500.
In Table 2, Major indication for induction of labor includes maternal, fetal, social or combination of these factors. These indications may also either be evident or anticipated [15]. Another study done by centers for disease controls Vital Statistics (USA) Induction rates do not seem to increase with age when you look at birth certificate data [16].
In Table 2, Studies showed that a higher percentage of nulliparous women were induced (36.4%) than multiparous women (27.2%) [17]. Previous research conducted in United Kingdom posits that increase women who are more educated may be able to more confidently advocate for themselves both before and during their pregnancy and birth [18]. Some previously published studies on childbirth intervention and labor induction, which have found that income-based measures of socioeconomic status have significant associations with induction of labor [19].
Table 5. Cross tabulate between women’s previous frequencies of induced labor according to their daily meal intake.
In Table 2, total of 9 (30%) were started their ANC visit during the period between 4 - 6 months (13 - 24 Weeks), followed by 3 (20%) who were started their ANC visit in between 7 - 9 months (25 - 36 weeks).
In Previous same study showed that the rate of induced labor was higher among laboring mother who had not ANC follow-up compared to the other counterpart. And there was statistically significant association between the ANC follow-up and induction of labor (P < 0.000) [20].
In Table 2, total of 12 (40%) had undergone induction once time previously, followed by 8 (27%) had undergone induction previously two times, while 6 (20%) had undergone previously three times, 4 (13%) more than four times. 21 (70%) were delivered Spontaneous Vagina delivery (SVD), 6 (20%) were Cesarean section (CS) and 3 (10%) instrumental vaginal delivery.
In Table 2, the current study showed that 22 (73%) gave a safe birth (a life newborn) through induced labor one time, followed by 2 (7%) two times. While 6 (20%) gave birth (dead newborn) through induced labor one time with their previous deliveries. A total of (60%) were delivered in public hospitals, followed by (23%) were delivered in private hospitals and 5 (17%) home delivery.
A Study conducted in Addis Ababa Army Referral Hospital showed out of 76 women who undergone induction about 59.7% women had successful induction [21]. In Aga Khan Hospital, Pakistan, (81.9%) that revealed an induced labor ended with vaginal delivery [5], King Khalid University Hospital who had registered (84%) of women had vaginal delivery considered as successful outcome of IOL [22]. This discrepancy could be due to the difference in hospital setup, skilled professional and availability of different method for applying induction. [22]. Overall rate of induction for the African region was 4.4%. Most inductions being performed between 37 and 41 weeks of gestation [19]. The laboring mother with the gestational age (<42 weeks) show an increase in chance of success for induced labor for about 9.47 times compared to the mothers who had underwent induced labor with gestational age having greater than to 42 weeks [20].
In Table 3, according to this study the primary reason for induction of labor was premature rupture of membranes (PROM) followed by for post-date and medical disorders with pregnancy. This finding was in line with study done in Ain Shams University Maternity Hospital, Egypt [23].
In other study done in Kingdom of Saudi Arabia post-term pregnancy was found to be the most common indications followed by diabetes mellitus in participated women [22]. While the common indications for induction in Nepal study was post term pregnancy [24].
Fetal structural condition was matters for induction of labor in this study. Mothers who pregnant anomalic fetuses were 5.7 times more likely to get induction of labor [8] [25].
7. Conclusions
The study revealed that prevalence of induction labor among women aged 15 - 49 who had undergone induction of labor at Shaafi hospital for the period of six months from October 2019 to March 2020 were 40 women out of 370 women who were derived at shaafi hospital from October 2019 to 31 March 2020.
The result showed that the majority of the respondents 18 (60%) were aged between 25 - 34 years, followed by 8 (27%) were aged between 25 - 34 yrs. While only 4 (8%) were between aged 35 - 44 yrs. While 21 (70%) were married, while 11 (37%) were primary level, while 7 (23%) were illiterate, 21 (70%) were housewife, followed by 4 (13%) were employed. 15 (50%) their monthly income was in between $300 - $400 monthly (Table 1).
The study showed that a total of 12 (40%) had undergone induction once time previously, followed by 8 (27%) had undergone induction previously two times, while 6 (20%) had undergone previously three times, 4 (13%) more than four times. 21 (70%) were delivered Spontaneous Vagina delivery (SVD), 6 (20%) were Cesarean section (CS) and 3 (10%) instrumental vaginal delivery (Table 2).
The result showed that the outcomes of labor 22 (73%) gave a safe birth (a life newborn) through induced labor one time, followed by 2 (7%) two times. Followed by 6 (20%) who gave birth (dead newborn) through induced labor one time with their previous deliveries (Table 2).
In addition post term 27 (90%), followed by responded intrauterine fetal death (IUFD) 2 (7%) Pregnancy induced hypertension (PIH) 1 (3%) were found to be the main reason for their induction of labor (Table 3).
The study revealed that the socio-demographic and obstetrical determinants such as age, and daily meal intake as well as antenatal care visit during pregnancies and reasons for induction; e.g. Post term (Post-mature), Intrauterine fetal death (IUFD) and Pregnancy induced hypertension (PIH) showed significant association to the induced labor while non-significant have been observed with mother’s gestational age and their induction of labor (Table 4 and Table 5).
Recommendation
· The ministry should develop a national guideline of induction of labor for health workers in public and private health care facilities
· The study recommended that ministry of health should ensure that every pregnant woman has access to skilled maternal counseling to improve quality of antenatal care.
· To train all health workers especially (doctors, nurse and midwives,) in the health facility level on a national guideline of induction of labor and monitor its implementation to and ensure that all induction of labor procedures are performed only for acceptable indications across the country.
