The frequency of acceptance of oral glucose tolerance test in Turkish pregnant women: A single tertiary center results

OBJECTIVE: It is thought that there is not enough data about the frequency of acceptance of oral glucose tolerance test (OGTT) in Turkish pregnant women. The aim of this study was to investigate the frequency of acceptance of OGTT among participants in our single tertiary center.
METHODS: The data of non-diabetic 344 pregnant women seen at the Obstetrics Clinic of our hospital between September 2016 and September 2017 were obtained from the hospital records. Women who did not have regular follow-up during pregnancy were excluded. One of the two or one-step approaches was used in the diagnosis of gestational diabetes mellitus (GDM) depending on the choice of the physician following the patient.
RESULTS: There were 223 subjects eligible for the study. One hundred seventy-seven pregnant women (79.4%) accepted to do OGTT. We determined that 46 women (20.6%) did not complete at least one OGTT, of whom 74% (n=34) never completed the recommended screening test in this cohort. The overall frequency of GDM was approximately 15.2% (n=34). OGTT acceptability was higher among pregnant women with university graduates (p=0.02). Adverse pregnancy outcomes were similar between the accepted and rejected groups. Among the reasons for OGTT rejection, the media had a significant influence (n=35).
CONCLUSION: Our results show that a significant percentage of patients refused to do OGTT. Therefore the actual frequency of pregnant women with GDM could not be determined. One way to increase compliance may be recommending only the one-step test for pregnant women in countries with a high rejection rate of OGTT.

Türk Populasyonundaki Gebelerin Oral Glukoz Tolerans Testini Kabul Etme Sýklýðý: üçüncü basamak tek merkez sonuçlarý

Giriþ: Türk popülasyonundaki gebelerde oral glukoz tolerans testinin (OGTT) kabul edilme sýklýðý ile ilgili yeterli veri olmadýðý düþünülmektedir. Bu çalýþmanýn amacý, üçüncü basamak merkezimizde katýlýmcýlar arasýnda OGTT’nin kabul edilme sýklýðýný araþtýrmaktýr.
Yöntem: Eylül 2016-Eylül 2017 tarihleri arasýnda hastanemizin Kadýn Hastalýklarý Kliniðinde görülen diyabetik olmayan 344 gebenin verileri hastane kayýtlarýndan elde edildi. Gebelik boyunca düzenli takibi olmayanlar çalýþma dýþý býrakýldý. Gestasyonel diyabet (GDM) tanýsýnda hastayý takip eden doktorun tercihine göre iki veya tek aþamalý yaklaþýmlardan biri kullanýldý.
Bulgular: Çalýþma için uygun olan 223 olgu vardý. Yüz yetmiþ yedi gebe kadýn (%79.4) OGTT yaptýrmayý kabul etti. Bu kohorttaki 46 kadýnýn (% 20.6) en az bir OGTT’yi tamamlamadýðýný belirledik, bunlarýn % 74’ü (n=34) önerilen tarama testini hiçbir zaman tamamlamadý. GDM sýklýðý yaklaþýk % 15.2 idi (n=34). Üniversite mezunu gebe kadýnlar arasýnda OGTT kabul edilebilirliði daha yüksekti (p=0.02). Olumsuz gebelik sonuçlarý kabul ve red eden grublar arasýnda benzerdi. OGTT rededilme nedenleri arasýnda medya önemli bir etkiye sahipti (n=35).
Tartýþma: Sonuçlarýmýz hastalarýn önemli bir yüzdesinin OGTT yaptýrmayý reddettiðini göstermektedir. Bu nedenle GDM' li gebe kadýnlarýn gerçek sýklýðý belirlenemedi. Uyumluluðu artýrmanýn bir yolu OGTT' nin reddedilme oranýnýn yüksek olduðu ülkelerdeki gebeler için sadece tek aþamalý test önermek olabilir. (NCI-2021-2-12/R1)
