INTRODUCTION: The study aimed to investigate the relationship between mid-trimester cervical length and pre-term delivery and maternal characteristics.
METHODS: Cervical length measurement was carried out in 98 pregnant women who presented to antenatal outpatient clinic between 20 and 24th weeks� pregnancy. Age, obstetric history, gravida, parity, the number of abortion, and body mass index (BMI) were also recorded. Births before 37th week formed preterm birth group, and those after 37th week formed term birth group.
RESULTS: Of pregnant women included in the study, 77 (78.6%) gave birth after 37th week of pregnancy, while 21(21.4%) gave birth before 37th week of pregnancy. Fourteen cases (14.3%) with cervical length under 25 mm, while 84 (85.7%) cases with cervical length over 25 mm. Twelve (12.24%) of the study group had a history of preterm birth. Of these cases, 11 (91.7%) had a recurrent pre-term birth. The rate of pre-term birth was higher in cases with a cervical length less than 25 mm compared to other cases (p<0.05). There was a significant relation between cervical length and age and BMI levels (p<0.05). No significant relation was found between parity and term and pre-term births (p>0.05). There was a significant relation between BMI and term and pre-term birth rates (p<0.01). The rate of pre-term birth was significantly higher in cases with previous history of pre-term birth (p<0.05).
DISCUSSION AND CONCLUSION: Mid-trimester short cervical length associated with presence of funneling, his-tory of preterm birth, and obesity. Both a history of pre-term birth and a short cervix were associated with preterm birth. Therefore, in this patient group, routine cervical length measurement at 20�24 pregnancy weeks is recommended.

Keywords: Cervical length, pregnancy; preterm birth; ultrasonography.

G�R�� ve AMA�: Bu �al��man�n amac� 2. trimesterdaki servikal uzunluk ile preterm do�um ve maternal �zellikler aras�ndaki ili�ki de�erlendirmektir.
Y�NTEM ve GERE�LER: �al��maya, hastanemiz antenatal poliklini�ine 20-24. gebelik haftalar�nda ba�vuran servikal uzunluk �l��m� yap�lan 98 gebe �al��maya dahil edildi. Ya�, v�cut kitle indeksi (VK�), obstetrik �yk�, gravida, parite ve abort say�lar� kaydedildi. Preterm do�um grubu 37. gestasyonel hafta �ncesi do�um, term do�um grubu 37. gestesyonel hafta sonras� do�um olarak tan�mland�.
BULGULAR: �al��ma grubunda 77 (%78.6) gebe 37. gebelik haftas�ndan sonra 21 (%21.4) gebe ise 37. gebelik haftas� �ncesinde do�um yapt�. Servikal uzunluk 14 (%14.3) hastada 25 mm�den k�sa, 84 (%85.7) hastada ise 25 mm�den uzun olarak tespit edildi. On iki (%12.24) hastam�z-da preterm do�um �yk�s� mevcuttu. Preterm do�um oran� servikal uzunlu�u 25 mm�den k�sa olan grupta anlaml� olarak y�ksek bulundu (p<0.05). Ya�, VK� seviyeleri ile servikal uzunluk aras�nda anlaml� ili�ki tespit edildi (p<0.05). Preterm/term do�um ve parite say�s� aras�nda ili�ki tespit edilemedi (p<0.05). Preterm ve term do�um oranlar� ile VK� aras�nda anlaml� ili�ki tespit edildi (p<0.05). Preterm do�um �yk�s� varl��nda preterm do�um oran� anlaml� olarak artmaktad�r (p<0.05).
TARTI�MA ve SONU�: Servikal hunile�me, preterm do�um �yk�s� ve obezite varl�� 2. trimester servikal uzunlu�unun k�sa olmas� ile ili�kili tespit edildi. Bu nedenle bu hasta gruplar�nda 20-24. gebelik haftalar�nda rutin servikal uzunluk �l��m� yap�lmas� �nerilmektedir.

Anahtar Kelimeler: Gebelik, preterm do�um; servikal uzunluk; ultrasonografi.
