**'' Prolapsed umbilical cord'' – Prolapse of the umbilical cord happens when the fetus is not in a correct position in the pelvis. Membranes rupture and the cord is pushed out through the cervix. When the fetus pushes on the cervix, the cord is compressed and blocks blood and oxygen flow to the fetus. The mother has approximately 10 minutes to get to a doctor before there is any harm done to the fetus.
**''Monoamniotic twins
Monoamniotic twins are identical or semi-identical twins that share the same amniotic sac within their mother's uterus. Monoamniotic twins are always monochorionic and are usually termed Monoamniotic-Monochorionic ("MoMo" or "Mono Mono") twins. ...
'' – These twins share the same placenta and the same amniotic sac and therefore can interfere with each other's umbilical cords. When entanglement of the cords is detected, it is highly recommended to deliver the fetuses as early as 31 weeks.
**''Umbilical cord length'' - A short umbilical cord (<30 cm) can affect the fetus in that fetal movements can cause cord compression, constriction, and rupture. A long umbilical cord (>72 cm) can affect the fetus depending on the way the fetus interacts with the cord. Some fetuses grasp the umbilical cord but it is yet unknown as to whether a fetus is strong enough to compress and stop blood flow through the cord. Also, an active fetus, one that frequently repositions itself in the uterus can accidentally entangle itself with the cord. A hyperactive fetus should be evaluated with ultrasound to rule out cord entanglement.
**''Cord entanglement'' - The umbilical cord can wrap around an extremity, the body or the neck of the fetus. When the cord is wrapped around the neck of the fetus, it is called a nuchal cord
A nuchal cord is when the umbilical cord becomes wrapped around the fetus's neck. Symptoms present in the baby shortly after birth from a prior nuchal cord may include duskiness of face, facial petechia, and subconjunctival bleeding, bleeding in t ...
. These entanglements can cause constriction of blood flow to the fetus. These entanglements can be visualized with ultrasound.
**''Torsion'' – This term refers to the twisting of the umbilical around itself. Torsion of the umbilical cord is very common (especially in equine stillbirths) but it is not a natural state of the umbilical cord. The umbilical cord can be untwisted at delivery. The average cord has three twists.

- If a pregnant woman gets trapped in a building fire, the smoke and fumes can kill an unborn child.
A pregnant woman sleeping on her back after 28 weeks of pregnancy may be a risk factor for stillbirth.
After a stillbirth there is a 2.5% risk of another stillbirth in the next pregnancy (an increase from 0.4%).
In the United States, highest rates of stillbirths happen in pregnant women who:
* are of low socioeconomic status
* are aged 35 years or older
* have chronic medical conditions such as diabetes, high blood pressure, high cholesterol, etc.
* are African-American
* have previously lost a child during pregnancy
* have multiple children at a time (twins, triplets, etc.)
Diagnosis
It is unknown how much time is needed for a fetus to die. Fetal behavior is consistent and a change in the fetus' movements or sleep-wake cycles can indicate fetal distress. A decrease or cessation in sensations of fetal activity may be an indication of fetal distress Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation.

These are sporadic if constriction is due to a change in the fetus' or mother's position, and may become worse or more frequent as the fetus grows.

. How the diagnosis of stillbirth is communicated by healthcare workers may have a long-lasting and deep impact on parents. People need to heal physically after a stillbirth just as they do emotionally. In Ireland, for example, people are offered a 'cuddle cot', a cooled cot which allows them to spend a number of days with their child before burial or cremation.
Delivery
In single stillbirths, common practice is to induce labor for the health of the mother due to possible complications such as exsanguination. Induction and labor can take 48 hours. In the case of various complications such as preclampsia, infections, multiples(twins), emergency Cesarean may occur.
Epidemiology
The average stillbirth rate in the United States is approximately 1 in 160 births, which is roughly 26,000 stillbirths each year. In Australia, England, Wales, and Northern Ireland, the rate is approximately 1 in every 200 births; in Scotland, 1 in 167. Rates of stillbirth in the United States have decreased by about two-thirds since the 1950s.

impact is often underestimated. In the early 20th century, when a stillbirth occurred, the baby was taken and discarded and the parents were expected to immediately let go of the attachment and try for another baby. In many countries, parents are expected by friends and family members to recover from the loss of an unborn baby very soon after it happens. Societally-mediated complications such as financial hardship and depression are among the more common results. A stillbirth can have significant psychological effects on the parents, notably causing feelings of guilt
Guilt may refer to:
*Guilt (emotion), an emotion that occurs when a person feels that they have violated a moral standard

in the mother. Further psycho-social effects on parents include apprehension, anger, feelings of worthlessness and not wanting to interact with other people, with these reactions sometimes carried over into pregnancies that occur after the stillbirth. Men also suffer psychologically after stillbirth, although they are more likely to hide their grief and feelings and try to act strong, with the focus on supporting their partner.
Legal definitions
Australia
In Australia, stillbirth is defined as a baby born with no signs of life that weighs more than 400 grams, or more than 20 weeks in gestation. They legally must have their birth registered.
Austria
In Austria, a stillbirth is defined as a birth of a child of at least 500g weight without vital signs

in 1950 is as follows:
:"Fetal death" means death prior to the complete expulsion or extraction from its mother of a product of human conception, irrespective of the duration of pregnancy and which is not an induced termination of pregnancy. The death is indicated by the fact that after such expulsion or extraction, the fetus does not breathe or show any other evidence of life, such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles. Heartbeats are to be distinguished from transient cardiac contractions; respirations are to be distinguished from fleeting respiratory efforts or gasps.
Germany
In Germany, a stillbirth is defined as the birth of a child of at least 500g weight without blood circulation or breath. Details for burial vary amongst the federal states.
Republic of Ireland
Since 1 January 1995, stillbirths occurring in the Republic of Ireland must be registered; stillbirths that occurred before that date can also be registered but evidence is required. For the purposes of civil registration, s.1 of the Stillbirths Registration Act 1994 refers to "...a child weighing at least 500 grammes, or having reached a gestational age of at least 24 weeks who shows no signs of life."
Netherlands
In the Netherlands, stillbirth is defined differently by the Central Bureau of Statistics (CBS) and the Dutch Perinatal Registry (Stichting PRN). The birth and mortality numbers from the CBS include all livebirths, regardless of gestational duration, and all stillbirths from 24 weeks of gestation and onwards. In the Perinatal Registry, gestational duration of both liveborn and stillborn children is available. They register all liveborn and stillborn children from 22, 24 or 28 weeks of gestation and onwards (dependent on the report: fetal, neonatal or perinatal mortality). Therefore, data from these institutions on (still)births can not simply be compared one-on-one.
United Kingdom
The registration of stillbirths has been required in England and Wales from 1927 and in Scotland from 1939 but is not required in Northern Ireland. Sometimes a pregnancy is terminated deliberately during a late phase, for example due to congenital anomaly. UK law requires these procedures to be registered as "stillbirths".

collects statistical information on "live births, fetal deaths, and induced termination of pregnancy" from 57 reporting areas in the United States. Each reporting area has different guidelines and definitions for what is being reported; many do not use the term "stillbirth" at all. The federal guidelines suggest (at page 1) that fetal death and stillbirth can be interchangeable terms. The CDC definition of "fetal death" is based on the definition promulgated by the World Health Organization in 1950 (see section above on Canada). Researchers are learning more about the long term psychiatric sequelae of traumatic birth and believe the effects may be intergenerational
The federal guidelines recommend reporting those fetal deaths whose birth weight is over 12.5 oz (350 g), or those more than 20 weeks gestation. Forty-one areas use a definition very similar to the federal definition, thirteen areas use a shortened definition of fetal death, and three areas have no formal definition of fetal death. Only 11 areas specifically use the term 'stillbirth', often synonymously with late fetal death; however, they are split between whether stillbirths are "irrespective of the duration of pregnancy", or whether some age or weight constraint is applied. A movement in the U.S. has changed the way that stillbirths are documented through vital records. Previously, only the deaths were reported. However, 27 states have enacted legislation that offers some variation of a birth certificate as an option for parents who choose to pay for one. Parents may not claim a tax exemption for stillborn infants, even if a birth certificate is offered. To claim an exemption, the birth must be certified as live, even if the infant only lives for a very brief period.
