Description
Bilge Cetinkaya Demir and colleagues tracked cervix length in pregnancy in 2026. Early birth remains a leading cause of infant death and harm. Screening usually targets high-risk women. Yet many early births happen in low-risk women. Mid-pregnancy cervix checks may come too late for prevention. The team asked whether first-trimester checks could predict later length. They scanned nearly three hundred low-risk women three times. Scans ran from early to mid pregnancy.
Cervix length grew across the scans on average. Growth came mainly from the upper segment of the cervix. The lower segment stayed stable. First-trimester length predicted early birth only weakly. Its accuracy score fell well short of a strong test. The authors back continued mid-pregnancy checks for risk sorting. Early checks alone should not replace them, they conclude. The work also clarifies how the cervix changes shape over time.
