Weekly differences in the prevalence of a short cervix at 18+0 to 23+6 weeks of gestation in pregnant women with and without a history of preterm delivery

Objective: To estimate weekly differences in the prevalence of a short cervix during the period of 18+0 to 23+6 weeks of gestation in pregnant women with and without a history of previous preterm delivery (PTD).
Design: Observational study
Methods: Setting and participants: 20,002 pregnant women, 18,591 without a history of previous PTD (low risk) and 1,411 with at least one previous PTD (high risk) were evaluated at 18+0 to 23+6 weeks + days of gestation. Weekly differences in the prevalence of a short cervix ( ≤25 mm, ≤20 mm, and ≤15mm) between women with and without previous PTD were estimated.
Results: High-risk women had a significantly higher prevalence of a short cervix, defined either as ≤25 mm (4.4% vs. 2.2%; p
