“…Similar findings were seen in a study done by Crowther, 11 Smith et al 14 and Hack et al 15 Dizygocity was more common in this study than monozygosity which was similar to the observations made by Lewi and Deprest, 16 and Katz et al 17 In cases of monochorionicity, more of the second twins had Apgar score <7 than the first twin (MCDA: 6 vs. 4; MCMA: 6 vs. 3) similar to the study done by Shrim et al 18 Perinatal mortality rate in this study was similar to the study done by Hack et al, 15 Wieczorek and Krasomski, 19 Victoria et al, 20 Sperling et al, 21 and Oldenburg et al…”

Aims:The purpose of this study was to determine the perinatal outcome of the second twin compared to the first one.Methods: This is a hospital based comparative study of 60 pregnant women with twin pregnancy at Paropakar Maternity and Women's Hospital, Kathmandu from 14 January 2013 to13 April 2013. Apgar score and admission to neonatal intensive care unit of the first and the second twins were studied in relation to the gestational age, chorionicity, mode of delivery, interdelivery interval and birth weight. Mc Nemars test was used with 0.05 as the level of significance.Results: Among 60 sets of twins, Apgar score of the second twin was found to be lower than the first one (p=0.02) in general and in preterm gestation (p=0.049), dichorionic diamniotic chorionicity (p=0.012), vaginal delivery (p<0.001), inter-delivery interval of <30 minutes (p=0.007) and birth weight discordance of <30 % (p=0.014). Admission to neonatal intensive care unit was not significant (p=0.5).Conclusions: Second twin had low Apgar score and the neonatal admission rate was similar for both twins.

“…A higher twin birth rate has been reported in older mothers (Astolfi et al, 2003;Jewell & Yip, 1995) and mothers with higher parity (Astolfi et al, 2003;Katz et al, 2001). The variation in the twinning rate with maternal age and parity is largely due to variations in dizygotic twinning and is thought to be associated with gonadotrophin production (Katz et al, 2001).…”

Recently, there has been a significant increase in the rate of multiple births in most developed countries. However, few population-based studies have been conducted in China regarding the epidemiology of twin births in recent years. We performed a descriptive analysis of twin births from 1993 to 2005 using data from a population-based perinatal care program in southeast China. The twin birth rate in southeast China was 0.65%, and the twin birth rates from 1993 to 2005 fluctuated between 0.60% and 0.70%. During the three periods of 1993-1996, 1997-2000, and 2001-2005, the twin birth rate increased from 0.57% to 0.71% in urban areas (p = .005) and from 0.59% to 0.68% in mothers who had an education level of high school or higher (p = .046). After 2000, the twin birth rate of primiparae 30 years of age and older significantly increased from 0.72% to greater than 1.20%. We concluded that the twin birth rates in southeast China from 1993 to 2005 stayed constant in the overall population but increased in certain subgroups of women, presumably due to increased use of fertility treatment and the development of assisted reproductive technology.

Objective: To determine the socio demographic characteristics, clinical presentation and obstetric outcome at delivery and immediate postpartum period of twin gestation in a periurban hospitalMaterial & Methods: An observational study was conducted between January 2000 to December 2004 at Institute of Child and Mother Health. All twin pregnancy irrespective of gestational age admitted in the in-patient department of Institute of Child and Mother Health for delivery and also those undiagnosed cases found to have twin birth were enrolled in the study consecutively from January 2001 to December 2004. Data on socio-demographic factors, predisposing factors for twin gestation and obstetric characteristics was collected using a structured questionnaire. Hospital records were consulted for recording the investigation reports and management options. The outcome variables were maternal complications during antenatal, intranatal and immediate postnatal period, mode of delivery, birth weight and sex of newborn and fetal outcome. All twin pregnancies from the admitted obstetric patients were enrolled consecutivelyResults: During the study period there were 11,185 deliveries and among them 107 were twin gestation. About 22% were primigravida, 78.5% multigravida, 27.1% were illiterate. Most common age group were 24-29 years (39.4%). Antenatal care was availed by 71% of patients and 27.1% twins were not diagnosed till delivery. Family history of twin on maternal side was present in 58.1% and 31.8% had history of taking oral contraceptive immediately before the pregnancy. Ovulation inducing agents were given to 8.3% of twin. Presentations of fetus were both vertex 54.2%, 1st vertex and second breech 16%, and both breech 5.7%. About 55.1% were admitted with labor pain, 6.5% were undelivered second twin. Preterm birth was 27.2% and low birth weight of 1st baby 79.6% and second baby 80.9% respectively. Mode of delivery was vaginal delivery of both fetus 41.6%, caesarean section of both fetus 62.4%, and caesarean for second twin 3.1%. Same sex of both twins was found in 78% and male-male pair was 50%. There was one stillbirth, one conjoined twin and perinatal death was 11.2% Complications encountered during perinatal period were severe abdominal pain 9.3%, retained placenta in 7.3%; and post partum hemorrhage in 4.6% cases.Conclusion: Twin pregnancy is quite common and warrants specialized care during ante partum, intrapartum and postpartum period.Bangladesh J Obstet Gynaecol, 2012; Vol. 27(2) : 57-62
