The risk was greatest among the most obese women, the authors write in The Journal of the American Medical Association.
“The main message of the study is that maternal overweight and obesity increases the risk of fetal death, stillbirth and infant death,” said Dagfinn Aune, the study’s lead author, from Imperial College London.
“Since excess weight is a potentially modifiable risk factor, further studies should assess whether lifestyle and weight changes modifies the risk of fetal and infant death,” he told Reuters Health in an email.
Stillbirths, when a child dies in the womb toward the end of pregnancy, account for a large part of the estimated 3.6 million neonatal deaths that occur each year, the researchers point out.
Previous studies have linked women’s weight during pregnancy to the risk of their children dying in the womb or shortly after delivery due to complications. Some could not show their findings were not due to chance, however.
For the new study, the researchers pulled together data from 38 studies. Together, these included over 45,000 accounts of child deaths that occurred shortly before or after delivery, although a few studies counted deaths up to one year after birth.
According to the U.S. National Institutes of Health, a person of normal weight would have a body mass index (BMI) – which is a measure of weight in relation to height – between 18.5 and 24.9.
An adult who is 120 pounds and five feet, five inches tall, for example, would have a BMI of 20.
A BMI between 25 and 29.9 is considered overweight, and a score of 30 or above is considered obese.

A new study published in the American Journal of Obstetrics and Gynecology has found that women who give birth at home are 10 times more likely to have stillbirths; first-born children who are delivered at home are 14 times more likely to be stillborn. More from ABC News:

In the largest study of its kind, investigators at New York-Presbyterian/Weill Cornell Medical Center in New York City reviewed data from a sampling of 13 million of the nearly 17 million singleton full-term births in the United States between 2004-2007. These included births to parents of all races, ethnic groups and income levels.
Among their findings: Babies born at home were nearly 10 times more likely to be stillborn, and the risk of stillbirth increased to 14 times for firstborns. Babies born at home were also almost four times more likely to experience neonatal seizures or serious neurologic dysfunction compared with babies born in hospitals.
The study’s results were confirmed by analyzing birth certificate files from the National Center for Health Statistics to evaluate deliveries by physicians and midwives in the hospital and at home from 2007 to 2010. The researchers looked at Apgars, scores that assess the health of an infant one minute and five minutes after birth. A five-minute Apgar score of zero is considered a stillbirth. About 10 percent of these babies survive, though often with major health problems.
“Childbirth is one of the most wonderful moments in humanity, and people deserve the best of all circumstances, including enhancing the experience and reducing unnecessary interventions,” said Dr. Amos Grunebaum, chief of labor and delivery at New York-Presbyterian/Weill Cornell Medical Center, and the study’s lead author. “Having said that, it’s not only about experience. It’s also about making sure the baby is born safely.”
Grunebaum said that the study associated risk with the location of a planned birth, rather than the credentials of the person delivering the baby. When a child is born at home, typically there is only the midwife or doctor to address any unpredictable circumstances that arise, but in the hospital, a team of specialists can be mobilized in seconds if needed, he said.
