Lancet Study Considers Pregnancy Soon After Stillbirth Safe

However, "such nutritional depletion might not occur to the same extent after a pregnancy loss, and this may affect the optimal interpregnancy interval, explaining why it may be different after stillbirth and livebirth"

Conceiving within a year of stillbirth is not associated with increased risk of pregnancy loss, preterm birth, or any other health risk to the baby, finds a new study, challenging previous recommendations.

The World Health Organization (WHO) recommends women to wait for at least two years after a livebirth and at least six months after a miscarriage or induced abortion before conceiving again.

The study, published in The Lancet, showed that an interpregnancy interval of less than one year was not associated with increased risk of adverse birth outcomes in the next pregnancy, compared with an interval of at least two years.

This trend remained the same when adjusted for maternal age, number of previous births, and decade of delivery, the findings revealed.

“Our findings provide valuable evidence for recommended pregnancy spacing after a stillbirth,” said Annette Regan from Curtin University in Australia.

There is limited guidance available for planning future pregnancies after stillbirth, Regan said, adding, “we hope that our findings can provide reassurance to women who wish to become pregnant or unexpectedly become pregnant shortly after a stillbirth”.

For the study, the team included 14,452 births among mothers from Finland, Norway, and Australia, who had a stillbirth in their previous pregnancy.

The researchers noted that there is difference in optimal intervals following livebirth and stillbirth.

“Without sufficient time to recover from a previous pregnancy, women may be at increased risk of entering a reproductive cycle with poor nutritional status, which has been linked to increased risk of foetal growth restriction and birth defects,” Regan said.

However, “such nutritional depletion might not occur to the same extent after a pregnancy loss, and this may affect the optimal interpregnancy interval, explaining why it may be different after stillbirth and livebirth”, she said. (IANS)

Children Born to Women with Hyperemesis may be at Increased Risk of Autism

This could lead to dangerous dehydration and inadequate nutrition during pregnancy

Children whose mothers had hyperemesis gravidarum, a severe form of morning sickness, during pregnancy were 53 per cent more likely to be diagnosed with an autism spectrum disorder, a study said.

Hyperemesis gravidarum occurs in less than five per cent of pregnancies. Affected women experience intense nausea and are unable to keep down food and fluids.

This could lead to dangerous dehydration and inadequate nutrition during pregnancy.

“This study is important because it suggests that children born to women with hyperemesis may be at an increased risk of autism,” said the study’s lead author Darios Getahun, Kaiser Permanente Southern California Department of Research and Evaluation.

“Awareness of this association may create the opportunity for earlier diagnosis and intervention in children at risk of autism,” Getahun said,

For the study published in the American Journal of Perinatology, researchers reviewed the electronic health records of nearly 500,000 pregnant women and their children born between 1991-2014 in Southern California.

They compared children whose mothers had a diagnosis of hyperemesis gravidarum during pregnancy to those whose mothers did not.

The researchers found that exposure to hyperemesis gravidarum was associated with increased risk of autism when the disease was diagnosed during the first and second trimesters of pregnancy, but not when it was diagnosed only in the third trimester.

Exposure to the disease was associated with the risk of autism regardless of the severity of the mother’s hyperemesis gravidarum, the study said.

The results are consistent with the hypothesis that women experiencing hyperemesis gravidarum have a poor nutritional intake, which might, in turn lead to potential long-term neurodevelopment impairment in their children. (IANS)
