Factors associated with umbilical cord clamping in term newborns.
Juliana Karine Rodrigues Strada, Leticia Becker Vieira, Helga Geremias Gouveia and 3 others
PMID 35348571WHAT IT FOUND
In 300 term births, 53.7% had delayed cord clamping.
Needing resuscitation or holding the newborn at or below vaginal level was associated with early clamping; skin-to-skin contact was associated with delayed clamping. Records often missed or disagreed with observed clamping.
Key findings
01Of 300 mother-infant pairs, 53.7% had delayed/optimal cord clamping, and the median clamping time was 70.5 seconds.
02After adjustment, newborns held below the vaginal canal or at vaginal level, and newborns needing resuscitation, were associated with early clamping; skin-to-skin contact was associated with delayed clamping.
03Records missed clamping practice in 79 nurse records, 132 obstetrician records, and 21 pediatrician records, and agreement with observation varied by professional.

What it does not show
Women were selected by convenience and birth order, so selection bias is possible. The study was done in one university hospital in southern Brazil, so results may not apply to other settings. The study observed associations and did not test whether changing newborn position, resuscitation practice, or skin-to-skin contact changes clamping time. Some professionals did not record clamping time in all births, and record agreement with observation varied by professional.
The easy way to misread this
Do not conclude that holding the newborn on the mother or avoiding resuscitation will cause delayed clamping. The study observed associations in one hospital and did not test these practices.
