Twin pregnancy is associated with an increased risk of pre-term deliveries, perinatal morbidity, mortality and maternal complications, especially in developing countries. A descriptive study of all women who had twin pregnancies in a rural mission tertiary hospital over a 7-year period was undertaken. There were a total of 3,351 deliveries and 99 cases of twin deliveries during the study period giving an incidence of 29.5/1,000 or one in 33.8 deliveries. Some 60% of the twins were delivered by caesarean section, while 36.4% had vaginal delivery. A total of 4% had vacuum delivery and a combination of vacuum and caesarean delivery. Twinning rate increased with increasing age and parity. The majority of the patients were unbooked (65.7%). The study could not detect any differences in the birth weights of twin 1 compared to twin 2. There were more females (52%) than males (48%). Low birth weight babies constituted 57.1% of twins. There were 26 perinatal deaths giving rise to a perinatal mortality rate of 131/1,000 and there was no difference in the perinatal mortality rate in the unbooked (131/1,000) and the booked (132/1,000). ). Booking status had no significant effect on perinatal mortality of twins and singletons, p value = 0.65. Singletons had significantly more caesarean section and vaginal delivery than twins, p value < 0.0001. Prematurity was the chief cause of perinatal death (65.4%). The most common mode of presentation was cephalic/cephalic (58.6%), followed by cephalic/breech (29.2%), breech/cephalic (7.1%) and breech/breech (5.1%). There was no maternal death.
双胎妊娠与早产、围产期发病率、死亡率及孕产妇并发症风险增加相关，在发展中国家尤其如此。对一家农村教会三级医院7年间所有双胎妊娠妇女进行了一项描述性研究。研究期间共有3351例分娩，其中99例为双胎分娩，发病率为29.5/1000，即每33.8例分娩中有1例双胎分娩。约60%的双胎通过剖宫产分娩，36.4%经阴道分娩。共有4%采用真空吸引分娩以及真空吸引与剖宫产联合分娩。双胎发生率随年龄和产次增加而上升。大多数患者未登记预约（65.7%）。该研究未发现双胎1与双胎2出生体重有任何差异。女性（52%）多于男性（48%）。低体重儿占双胎的57.1%。有26例围产期死亡，围产儿死亡率为131/1000，未登记预约者（131/1000）和已登记预约者（132/1000）的围产儿死亡率无差异。预约登记状态对双胎和单胎围产儿死亡率无显著影响，p值 = 0.65。单胎剖宫产和阴道分娩显著多于双胎，p值<0.0001。早产是围产儿死亡的主要原因（65.4%）。最常见的胎位是头位/头位（58.6%），其次是头位/臀位（29.2%）、臀位/头位（7.1%）和臀位/臀位（5.1%）。无孕产妇死亡。
