There is an increased likelihood of prolonged pregnancy with increasing second-trimester cervical length, according to a study of 9,165 nulliparous women who underwent routine cervical length measurement between 18 and 24 weeks of gestation. A secondary analysis included only women who achieved at least 39 weeks of gestation. Researchers found:
• 16.2% of women had a prolonged pregnancy.
• Women in increasing cervical length quartiles were more likely to experience a prolonged pregnancy.
• The secondary analysis was consistent with the overall analysis.
