Abstract

Amaç: Bu çalışmanın amacı, vajinal doğum yapmış miadında gebelerde çeşitli antenatal faktörlerin plasenta ağırlığını etkileyip etkilemediğini değerlendirmektir.
Gereç ve Yöntemler: Bu gözlemsel çalışma Ocak-Ağustos 2022 tarihleri arasında Karaman Eğitim ve Araştırma Hastanesi'nde yapılmıştır. Otuz yedinci gebelik haftasını tamamlayarak vajinal doğum yapan 630 gebe bu çalışmaya alındı. anne yaşı, paritesi, vücut kitle indeksi, kronik hastalıkları, plasenta ağırlığı, yenidoğanların da doğum ağırlığı, boyu ve cinsiyeti kaydedildi.Bu çalışmanın birincil sonucu, plasenta kitlesini etkileyebilecek anne yaşı, vücut kitle indeksi, parite, anemi ve kronik hastalık ve yenidoğan ağırlığı gibi faktörleri değerlendirmektir. Hamilelik sırasında tütün kullanımının yanı sıra cinsiyetin etkisinin değerlendirilmesi bu çalışmanın ikincil bir sonucuydu. Plasenta ağırlığını etkileyen faktörler değerlendirilirken Enter yöntemi ile lineer regresyon analizleri uygulandı.
Bulgular: Çalışmanın bulgularını değerlendirdiğimizde, doğum ağırlığının ve paritenin plasenta ağırlığı üzerinde istatistiksel olarak anlamlı bir etkiye sahip olduğunu gözlemledik (sırasıyla, p>0,001 ve p=0,024). Primipar gebelerde ortalama plasenta ağırlığı 580 gram iken, multiparlarda 600 gram (p=0,008). 13 hastalık kategorisi incelendiğinde sadece gestasyonel diyabetin plasenta ağırlığı üzerine anlamlı etkisi olduğu gösterildi (p=0,024). Annelerin vücut kitle indeksi , hemoglobin düzeyi ≤11 gr/dL olan annedeki anemi ve sigara alışkanlığının plasenta ağırlığı üzerinde etkisi bulunmamıştır.
Sonuç: Bu çalışmanın sonuçları, parite, yenidoğanın doğum ağırlığı ve annede gestasyonel diyabet varlığının plasenta ağırlığını etkileyen kritik faktörler olduğunu desteklemektedir

Evaluation of antenatal factors affecting placental weight in term pregnancies

Abstract

ABSTRACT:

Objective: The aim of this study was to evaluate whether various antenatal factors affect placental weight in term pregnant women who gave birth vaginally.

Materials and Methods: This observational study was conducted between January and August 2022 in Karaman Training and Research Hospital. Six hundred and thirty parturients after thirtyseventh gestational week with vaginal delivery were enrolled to this study. The maternal age, parity, body mass index, chronic diseases, and placental weight, weight, length and gender of he newborns were documented.
Primary outcome of this study was to evaluate the factors such as age, body mass index, parity, anemia and chronic disesase of mothers and weight of the newborns that may affect placental mass. Assessment of the influence of gender as well as tobacco usage during pregnancy was a secondary outcome of this study. Linear regression analyses with Enter methos was applied while evaluating the factors affecting placental weight.
Results: As we evaluated the findings of the study, we found that birth weight and parity had a statistically significant influence on placental weight (p>0,001 and p=0,024 ,respectively). In primipar pregnants , the average weight of the placenta was 580 grams, whereas it was 600 grams in multiparas (p=0,008). Only gestational diabetes was shown to have a significant effect on placental weight when 13 disease categories were investigated (p=0,024).Body mass index of mothers , maternal anemia with hemoglobin level ≤11 gr/dL and smoking habitus had no effect on placental weight.
Conclusion: The results of this study support , parity , birthweight of the newborn and gestational diabetes mellitus are
critical factors affecting placental weight.
