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)

Researchers Claim, Men Aged 45 And Older Can Experience Decreased Fertility

Infants born to older fathers were found to be at higher risk of premature birth, late still birth, low birth weight, higher incidence of newborn seizures and birth defects such as congenital heart disease and cleft palate.

Men who delay starting a family have a ticking “biological clock” — just like women — that may affect the health of their partners and children, according to the researchers.

Men who delay fatherhood should consult their doctor and consider banking sperm before age 35, said the study which reviewed 40 years of research on the effect of parental age on fertility, pregnancy and the health of children.

“While it is widely accepted that physiological changes that occur in women after 35 can affect conception, pregnancy and the health of the child, most men do not realize their advanced age can have a similar impact,” said Gloria Bachmann, Director of the Women’s Health Institute at Rutgers University’s Robert Wood Johnson Medical School.

The study, published in the journal Maturitas, found that men aged 45 and older can experience decreased fertility and put their partners at risk for increased pregnancy complications such as gestational diabetes, preeclampsia and preterm birth.

Infants born to older fathers were found to be at higher risk of premature birth, late still birth, low birth weight, higher incidence of newborn seizures and birth defects such as congenital heart disease and cleft palate.

As they matured, these children were found to have an increased likelihood of childhood cancers, psychiatric and cognitive disorders, and autism.

The study also found that older men struggled with fertility issues even if their partner was under 25.

“While women tend to be more aware and educated than men about their reproductive health, most men do not consult with physicians unless they have a medical or fertility issue,” Bachmann said.

She recommended that physicians counsel older men as they do older women on the effect their age will have on conception, pregnancy and the health of their child. (IANS)
