ABSTRACT: Objectives: Although an asymptomatic short cervix is a risk factor for spontaneous
preterm birth (SPTB), the risk factors for SPTB among those with short cervix
remain unknown. We herein investigated risk factors for preterm delivery (PTD)
at Methods: This was a retrospective study. Seventy-three asymptomatic pregnant women with
a sonographic short cervix (excluding visible bulging fetal membranes) were
selected, and the relationship between clinical or biochemical risk factors and
preterm delivery (PTD) at Results: Thirteen
cases (17.8%) had PTD at ≥34 weeks (p dentified CM-IL-8 ≥ 803.5 ng/mL [21.3 (3.0
- 260), p = 0.002] and cervical
length ≤15 mm [17.1 (1.9 - 517), p =
0.008] as independent risk factors for PTD at Conclusions: Evaluation for cervical inflammation may be necessary for appropriate treatment
strategies in asymptomatic pregnant women with a short cervix. Cervical
inflammation warrants further study.
