Abstract

Objective: High-risk pregnancy is a situation associated with pregnancy involving a real or potential risk for the health and well-being of the mother and the fetus. Our study aimed to examine the preterm labor conditions of pregnant women followed up at a high-risk pregnancy outpatient clinic and related factors. Material and Methods: Designed as a retrospective cohort study, the study was carried out with the participation of 293 pregnant women who presented to a high-risk pregnancy outpatient clinic in the Batman province of Turkey and were followed up between March 2017 and January 2019. Results: The top three high-risk conditions determined in the pregnant women were pregnancy over the age of 35 (n=83, 28.3%), pregnancy in a shorter interval than two years (n=71, 24.2%) and consanguineous marriage (n=60, 20.5%), respectively. Twentypoint-one percent (n=59) of the pregnant women had preterm labor. It was determined that the rates of caesarean section births and births at a private hospital among the pregnant women who had preterm labor were significantly higher in comparison to the pregnant women who gave birth at term (p=0.001, p=0.037, respectively). It was determined that the risk of preterm labor increased OR=5.6 (1.2-25.6) times in the pregnant women with anemia, OR=12.5 (1.3-122.7) times in those with intrauterine fertilization and OR=32.6 (3.2-332.5) times in those with multiple pregnancies. Conclusion: Anemia, multiple pregnancy and intrauterine fertilization increase the risk of preterm labor. Quality prenatal care services are important in terms of protecting the health of the mother and the newborn.

Abstract

Amaç: Riskli gebelik annenin ve fetüsün sağlığı veya iyiliği için gerçek veya potansiyel bir tehlikeye sahip hamilelikle ilişkili bir durumdur. Çalışmamızda riskli gebelik polikliniğinde takibi yapılan gebelerin preterm eylem durumu ve ilişkili faktörlerin incelenmesi amaçlanmıştır. Gereç ve Yöntem: Retrospektif kohort olarak tasarlanan bu çalışma Batman ilinde (Türkiye) riskli gebe polikliniğine başvuran Mart 2017- Ocak 2019 tarihleri arasında takibi yapılan 293 gebe ile gerçekleştirilmiştir. Bulgular: Gebelerde tespit edilen ilk üç risk durumu sırasıyla 35 yaş üzeri gebelik (n=83, %28,3), iki yıldan kısa aralıklı gebelik (n=71, %24,2), akraba evliliği (n=60, %20,5) şeklindedir. Riskli gebelerin %20,1’inde (n=59) preterm eylem gerçekleşmiştir. Preterm eylem gerçekleşen gebelerin miadında doğum yapan gebelere göre sezaryen doğum ve özel hastanede doğum yapma durumu istatistiksel olarak fazla olduğu tespit edilmiştir (sırasıyla p=0,001, p=0,037). Preterm eylem riski değerlendirildiğinde, anemisi olan gebelerde OR=5,6 (1,2-25,6) kat, intrauterin fertilizasyon olan gebelerde OR=12,5 (1,3-122,7) kat, çoğul gebelerde OR=32,6 (3,2-332,5) kat arttığı tespit edilmiştir. Sonuç: Anemi, multiparite ve intrauterin fertilizasyon preterm eylem riskini artırmaktadır. Kaliteli doğum öncesi bakım hizmetleri gebe ve bebek sağlığını korumada önemlidir.
