Stillbirth

The death of a baby in the womb at or after the 20th week of pregnancy. It can happen before or during delivery. In many cases the cause remains unknown. In a large US study that examined stillbirths in detail, a probable cause was found in about six in ten, most often a problem with the pregnancy itself or with the placenta.

Overview

Technical summary

Condition of the fetus (recipient fetal), defined in MedlinePlus and by the NIH as fetal death at or after 20 weeks. The Stillbirth Collaborative Research Network (JAMA 2011) assigned a probable cause in 60.9% of 512 examined stillbirths; obstetric conditions and placental abnormalities were the most common causes. The AFFIRM trial (UK and Ireland, 2014 to 2016) found that a care package for reduced fetal movements did not reduce stillbirth. Burden figures: 1 in 160 US pregnancies (2011 report) and a 2015 worldwide estimate of 2.6 million.

Recognition

Fetal death from the 20th week of pregnancy onward, as MedlinePlus and the NIH define it; before delivery the diagnosis is made by checking whether the fetus's heart is beating (MedlinePlus)

Burden

  • Burden Observational Certainty not assessed

    A 2011 report from the Stillbirth Collaborative Research Network says stillbirth affects 1 in 160 pregnancies in the United States, equal to the number of infant deaths each year. It adds that rates are higher than in other developed countries and have stagnated over the past decade, and that there is a significant racial disparity in the rate of stillbirth that is unexplained.

  • Burden Observational Certainty not assessed

    The AFFIRM trial report states that 2.6 million pregnancies were estimated to have ended in stillbirth in 2015.
