Abstract

This study was conducted for the purpose of assessing, in the light of results of other research carried out in the present researchers' clinic and in Turkey, the status of twin pregnancies in Turkey, the incidence of twin births, perinatal and mortality rates associated with twin pregnancies, and the problems experienced in Turkey in cases of multiple and twin pregnancies. Materials and Methodology: The outcomes of twin births that occurred at the researchers' clinic during the period 2001–2009 were studied retrospectively. Seventeen studies conducted in Turkey on multiple and twin pregnancies during the years 1991–2010 were included in the study. Findings: It was observed that the mean multiple pregnancy rate in Turkey is 1.9% and the mean twin birth rate is 1.7%. It was also observed that a large majority (80–97.3%) of multiple pregnancies in Turkey are twin pregnancies. It was noted from Turkish literature that the mean gestational age of twins at birth varies between 33–36.2 weeks and that mean birthweights are 2065–2327 grams for the first-born twin and 1887–2262 grams for the second-born. These findings were observed to be lower than what is indicated in the literature. Perinatal and neonatal mortality, at 58–156/1000 and 40–98/1000 respectively, were seen to be higher than in the literature. Conclusion: It can be seen that preterm birth rates for twin pregnancies in Turkey are higher than what is indicated in the literature and that prenatal and neonatal mortality rates are also similarly higher.
