For the first time older mothers have a similar testimony about how a break should be done between pregnancies.


Expectant mothers should wait a year between birth of baby and new pregnancy to reduce risks to own health as well as baby.

However, researchers say that it is not necessary to wait 18 months, as advised by the world health organization, reports BBC.

Short intervals between pregnancies can cause premature birth and lead to low weight babies and increase the risks of infant and maternal mortality.

The researchers hope that the results are “reassuring” for older women.

Study author Dr. Wendy Norman stated that this was “encouraging news” for women over 35, who expect replenishment in the family.

“For the first time older mothers have a similar testimony about how a break should be done between the birth of children,” she said.

“Summer is the optimal interval is available for many women, and it is really worth going to decrease the risks”.

University of British Columbia (UBC) and the school of Public health Harvard University examined almost 150 000 deliveries in Canada and published the results in JAMA Internal Medicine.

The study showed that the interval from 12 to 18 months proved to be the ideal between birth and a new pregnancy.

Current recommendations of the world health organization talking about the interval of 24 months, or at least not less than 18 months.

The researchers also learned that:

– Pregnancy, which began less than 12 months after the previous one, carries risks for women at any age

– Greater risk of repeated pregnancy is for women over 35 years, at the same time as the risk for baby’s health the least, mothers from 20 to 34 years old

Women older than 35 years, who conceived a child six months after the previous birth, had a risk of maternal mortality or injury at 1.2% (12 cases per 1000 pregnancies)

– The span of 18 months between pregnancies reduced the risk to 0,5% (five per 1000)

Young women who become pregnant six months after the previous birth, had the risk of preterm birth at 8.5%
– He declined to 3.7% if they waited 18 months between pregnancies

The study’s lead author Laura Summers, said: “Our survey showed how risk mothers, including women older than 35 years, and infants, in the case where pregnancies follow one another”.

“These findings are especially important for older women, because they often deliberately don’t plan on doing between pregnancies”.

The researchers considered only the experience of canadian women, so it is unclear how their results can be applied worldwide.

Researcher Sonia Hernandez-Diaz noted that the findings demonstrated different risks for each age group.

“A short interval between pregnancies may indicate a second unplanned pregnancy, especially among young women.”

“Regardless of whether these risks are related to the fact that our bodies do not have time to recover if we got pregnant soon after giving birth, or factors associated with unplanned pregnancy, the recommendations are the same: it is necessary to improve access to postpartum contraception or refrain from sexual contacts with men after birth.”

Mend Forrester from the Royal College of obstetricians said the study was “useful, and it builds on previous research on birth intervals”.

“It’s a woman’s choice, how long to wait between pregnancies. It is important that they know about the risks, and make your choice, armed with the right information.”

“Health professionals always support a woman’s choice regarding her pregnancy”.
