A Cut-off Value for Gestational Weight Gain to Predict Large for Gestational Age Fetuses in a Low-risk Pregnant Population

Öz

Objective: To determine a cut-off value for gestational weight gain for the prediction of large for gestational age (LGA) fetuses Materials and Methods: This retrospective cohort study was conducted among 103 pregnant women who delivered at private hospitals in Izmir between January, 1, 2018 and December, 31, 2018. Patients were divided into two groups in terms of neonatal birth weight percentiles: 1) LGA group (≥90 percentile) (n=11), 2) Non-LGA Group (n=92). Demographic features and clinical characteristics were compared between the groups. Additionally, a cut-off value for maternal weight gain during pregnancy was determined for the prediction of LGA fetuses. Results: Significantly higher total weight gain during pregnancy and higher cesarean rates were observed in LGA group compared to non-LGA group (p values were 0.01 and 0.03, respectively). The cut-off value of 16.1 kg for gestational weight gain (72.7% sensitivity, 60.9% specificity) was determined for the prediction of LGA fetuses. Conclusion: Physicians should be cautious about excess weight gain during pregnancy.

Düşük Riskli Bir Gebe Populasyonunda Gebelik Haftasına Göre İri Fetusların Tahmin Edilmesi Amacıyla Gestasyonel Kilo Alımı İçin Bir Eşik Değer

Öz

Amaç: Doğum haftasına göre iri bebekleri (LGA) tahmin etmek amacıyla gestasyonel kilo alımı için bir eşik değer belirlemek. Gereç ve Yöntemler: Bu retrospektif kohort çalışması, 1 Ocak 2018 ile 31 Aralık 2018 tarihleri arasında İzmir'deki bir özel hastaneye başvuran 103 hamile kadın üzerinde gerçekleştirildi. Hastalar neonatal doğum ağırlığı persantilleri açısından iki gruba ayrıldı: 1) LGA grubu (≥90 persentil)(n=11) ve 2) LGA olmayan grup (n=92). Demografik özellikler ve klinik karakteristikler gruplar arasında karşılaştırıldı. Ayrıca, LGA fetüslerinin tahmini amacıyla hamilelik sırasında maternal kilo alımı için bir eşik değeri belirlendi. Bulgular: LGA grubunda diğer gruba göre belirgin olarak daha yüksek gestasyonel kilo alımı ve sezaryen oranı gözlendi (p değerleri sırasıyla 0.01 ve 0.03). LGA bebekleri tahmin etmek amacıyla gestasyonel kilo alımı için eşik değer olarak 16.1 kg belirlendi (% 72.7 duyarlılık,% 60.9 özgüllük). Sonuç: Hamilelik sırasında aşırı kilo alımı konusunda dikkatli olunmalıdır.
