Abstract

Amaç: Bu çalışmada yaş, parite, vücut kitle indeksi (VKİ)ile gebenin öyküsünde saptanan risk faktörlerinin 50 g glikoz tarama testi (OGTT) pozitifliği üzerine etkileri ve 50g OGTT’nin gestasyonel diabetes mellitus (GDM) tanısında etkinliği araştırıldı.
Yöntemler: Haziran 2012-Nisan 2020 tarihleri arasında özel bir kadın doğum kliniğinde takip edilen gebelerin tıbbi verileri bu retrospektif kohort çalışmasında incelendi. Gebeliğin24 ila 28. haftaları arasında tüm gebelere 50 g OGTT uygulandı. 1 saatlik venöz kan şekeri düzeyi 140 mg/dL üzerinde ise test pozitif kabul edildi ve tanı için 75 g 2 saatlik glikoz tolerans testi yapıldı. Gebelerin OGTT sonuçları, VKİ, parite, yaş ve diğer risk faktörlerinin GDM ile ilişkisi regresyon analizi ile incelendi.
Bulgular: Çalışmaya toplam 323 gebe dahil edildi. Ortalama yaş 29,35 (5,29) yıl ve ortalama vücut kitle indeksi 27,23 (6,07) kg/m2 idi. Grubun %35,9’unda en az bir risk faktörü mevcuttu. 50g OGTT’nin GDM tanısında duyarlılığı, özgüllüğü, pozitif prediktif değeri ve negatif prediktif değeri sırayla %100, %80,7, %27,5 ve %100 olarak bulundu. Regresyon analizinde ailede diyabet öyküsü GDM riskini 5,73 kat, GDM öyküsü 4,95 kat ve iri bebek öyküsü 1,43 kat artırdı.
Sonuç: İleri gebelik yaşı, gebelik öncesi VKİ ve öyküdeki risk faktörlerinin değerlendirilmesi GDM’nin öngörülmesi açısından faydalıdır. Ayrıca 50 g OGTT, anne ve bebeğin sağlığı için GDM tanısında yararlıdır.

The effects of age, parity and body mass index on 50 g oral glucose tolerance test results and its predictive value in gestational diabetes mellitus

Abstract

Aim: The aim of this study was to investigate the effects of age, parity, body mass index (BMI) and maternal risk factors on 50 g oral glucose tolerance test (OGTT) positivity and to evaluate the predictive value of 50 g OGTT in the diagnosis of gestational diabetes mellitus (GDM).
Methods: Medical data of pregnant women who were followed in a private obstetrics and gynecology clinic between June 2012 and April 2020 were analyzed in this retrospective cohort study. All patients underwent 50 g OGTT between 24 and 28 weeks of gestation. A 1-h postprandial venous plasma glucose cut-off of ≥140 mg/dL was considered positive for OGTT and the diagnosis was confirmed by 2-h 75 g OGTT. The relationship between the GDM and OGTT results, BMI, parity, age, and other maternal risk factors was analyzed in the regression analysis.
Results: A total of 323 pregnant women were included in the study. The mean age was 29.35 (5.29) years and the mean BMI was 27.23 (6.07) kg/m2. Among them, 35.9% had ≥1 risk factors. The sensitivity, specificity, positive predictive value, and negative predictive value of 50 g OGTT for GDM were 100%, 80.7%, 27.5%, and 100%, respectively. Regression analysis revealed that family history of diabetes, history of GDM, and macrosomic birth increased the GDM risk by 5.73, 4.95, and 1.43 folds, respectively.
Conclusion: Evaluation of advanced maternal age, pre-pregnancy BMI, and maternal risk factors is useful to predict GDM. In addition, 50 g OGTT is helpful in diagnosing GDM for both maternal and fetal health.
