“…A great number of them persevere with labor cases beyond what they can handle for career and economic reasons, and refer only when complications have set in. Although the perinatal mortality rate of 158.5/1000 births in this study is similar to that reported by other studies,15,19 it is higher than the perinatal mortality rate of 79.6/1000 for singleton births during the study period. Not all the women delivered at the hospital were from Bayelsa State, and some were referred from neighboring states.…”

BackgroundThe female is programmed to nurture one fetus and to take care of one neonate at a time; hence, twin pregnancy is associated with an increased risk of preterm deliveries, perinatal morbidity, and mortality and maternal complications. This study aimed to determine the twinning rate, and maternal and fetal outcomes of all twin pregnancies managed at the Niger Delta University Teaching Hospital Okolobiri.MethodsThe study is a 4-year descriptive retrospective evaluation of twin pregnancies managed at the Niger Delta University Teaching Hospital Okolobiri. Records of all pregnancies, booked and unbooked, managed from January 1, 2007 to December 31, 2010 were reviewed. Details of delivery and maternal and fetal outcomes were obtained using a pro forma designed for the study. Epi Info version 3.5.3 was used for statistical analysis. The Chi-square test was used to test for associations between variables. The level of significance was set at P ≤ 0.05.ResultsA total of 1341 deliveries including 41 cases of twin deliveries were recorded during the study period, giving an incidence of 30.6/1000. Twenty-nine (70.7%) of the patients were unbooked. The mean gestational age was 33.3 ± 2.6 weeks, and the mean fetal weight was 2.34 ± 0.54 kg. There were 13 perinatal deaths, with a perinatal mortality rate of 158.5/1000. There was no association between booking status and perinatal mortality rate (χ2 = 0.017, P = 1.000). Prematurity was the chief cause of perinatal death (65.4%). Maternal morbidities included anemia, wound infection, and genital sepsis. There were no maternal deaths.ConclusionThe twinning rate was high. There was a high perinatal mortality rate, with prematurity accounting for most of the mortality. There is a need for improved incubation/neonatal care for better outcomes with twin pregnancies in the hospital.

“…This is higher than the 10.6%15 but lower than the 60%19 reported from previous studies. The reason is that most of these patients were referred from private and public primary and secondary health facilities within and sometimes outside Bayelsa.…”

“…Perhaps more so, as the complete prevention of adverse prenatal factors remains an unattainable goal worldwide and the costs associated with even apparently healthy full-term multiple births may be prohibitive in resource-poor settings (35). The significant association of multiple gestations with the female sex in this study also warrants further research considering the dearth of corroborating evidence in the literature from this region (26), although some comparable studies also found a higher proportion of female twins in their population (9,12). While no direct association was found between multiple gestations and hearing screening failure, the risk of sensorineural hearing loss secondary to ineffective or inappropriate management of the other perinatal outcomes, such as severe hyperbilirubinaemia which is not uncommon in many resource-poor settings, should not be overlooked.…”

“…While multiple births are often disproportionately represented among preterm, low birthweight or intrauterine growth-restricted infants, maternal and infant morbidities following multiple pregnancies, unlike perinatal mortality rates, have not been thoroughly described in developing countries (9-13). Additionally, since preterm births, low birthweight, and intrauterine growth restriction are prominent risk factors for adverse neurodevelopmental outcomes worldwide, a better characterization of the perinatal consequences of multiple pregnancies should be helpful in facilitating resource allocation and closer developmental surveillance for infants at risk of developmental delays (6,14-18).…”

Compared to singletons, multiple births are associated with a substantially-higher risk of maternal and perinatal mortality worldwide. However, little evidence exists on the perinatal profile and risk of neurodevelopmental disabilities among the survivors, especially in developing countries. This cross-sectional study, therefore, set out to determine the adverse perinatal outcomes that are potential markers for neurodevelopmental disabilities in infants with multiple gestations in a developing country. In total, 4,573 mothers, and their 4,718 surviving offspring in an inner-city maternity hospital in Lagos, Nigeria, from May 2005 to December 2007, were recruited. Comparisons of maternal and infant outcomes between single and multiple births were performed using multivariable logistic regression and generalized estimation equation analyses. Odds ratio (OR) and the corresponding 95% confidence interval (CI) for each marker were estimated. Of the 4,573 deliveries, there were 4,416 (96.6%) singletons and 157 (3.4%) multiples, comprising 296 twins and six triplets together (6.4% of all live 4,718 infants). After adjusting for maternal age, ethnicity, occupation, parity, and antenatal care, multiple gestations were associated with increased risks of hypertensive disorders and caesarean delivery. Similarly, after adjusting for potential maternal confounders, multiple births were associated with low five-minute Apgar score (OR: 1.47, 95% CI 1.13-1.93), neonatal sepsis (OR: 2.16, 95% CI 1.28-3.65), severe hyperbilirubinaemia (OR: 1.60, 95% CI 1.00-2.56), and admission to a special-care baby unit (OR: 1.56, 95% CI 1.12-2.17) underpinned by preterm delivery before 34 weeks (OR: 1.91, 95% CI 1.14-3.19), birthweight of less than 2,500 g (OR: 6.45, 95% CI 4.80-8.66), and intrauterine growth restriction (OR: 9.04, 95% CI 6.62-12.34). Overall, the results suggest that, in resourcepoor settings, infants of multiple gestations are associated with a significantly-elevated risk of adverse perinatal outcomes. Since these perinatal outcomes are related to the increased risk of later neurodevelopmental disabilities, multiple-birth infants merit close developmental surveillance for timely intervention.

“…However, until now relatively few twin studies have been carried out in Sub-Saharan Africa [1,2,4,10]. Of the studies done [2,6,8-16], most have examined hospital records retrospectively [1,2]. Therefore there is a need of prospective cohort studies focusing specifically on the epidemiological and clinical aspects of twinning.…”

BackgroundDespite twinning being common in Africa, few prospective twin studies have been conducted. We studied twinning rate, perinatal mortality and the clinical characteristics of newborn twins in urban Guinea-Bissau.MethodsThe study was conducted at the Bandim Health Project (BHP), a health and demographic surveillance site in Bissau, the capital of Guinea-Bissau. The cohort included all newborn twins delivered at the National Hospital Simão Mendes and in the BHP study area during the period September 2009 to August 2011 as well as singleton controls from the BHP study area. Data regarding obstetric history and pregnancy were collected at the hospital. Live children were examined clinically. For a subset of twin pairs zygosity was established by using genetic markers.ResultsOut of the 5262 births from mothers included in the BHP study area, 94 were twin births, i.e. a community twinning rate of 18/1000. The monozygotic rate was 3.4/1000. Perinatal mortality among twins vs. singletons was 218/1000 vs. 80/1000 (RR = 2.71, 95% CI: 1.93-3.80). Among the 13783 hospital births 388 were twin births (28/1000). The hospital perinatal twin mortality was 237/1000.Birth weight < 2000g (RR = 4.24, CI: 2.39-7.51) and caesarean section (RR = 1.78, CI: 1.06-2.99) were significant risk factors for perinatal twin mortality. Male sex (RR = 1.38, CI: 0.97-1.96), unawareness of twin pregnancy (RR = 1.64, CI: 0.97-2.78) and high blood pressure during pregnancy (RR = 1.77, CI: 0.88-3.57) were borderline non-significant. Sixty-five percent (245/375) of the mothers who delivered at the hospital were unaware of their twin pregnancy.ConclusionsTwins had a very high perinatal mortality, three-fold higher than singletons. A birth weight < 2000g was the strongest risk factor for perinatal death, and unrecognized twin pregnancy was common. Urgent interventions are needed to lower perinatal twin mortality in Guinea-Bissau.
