Many older first-time moms face a dilemma when information technology comes to baby No. 2. The clock is ticking louder than e'er. But doctors advise waiting at least a twelvemonth and a half later giving birth before conceiving again.
This is the standard advice, based on multiple studies and public health guidelines. Only deciding when to attempt again tin exist a difficult decision — weighing medical chance against infertility risk. Now there are some new data points to factor in. A newspaper published Mon in the periodical JAMA Internal Medicine analyzed medical records from near 150,000 Canadian pregnancies to tease out how a mother's age influences the effects of a shorter-than-recommended interval between pregnancies.
For older moms in a bustle, the bad news is that the study adds evidence that conceiving within 12 months of a birth does mean heightened health risks for both mother and child. But epidemiologist Laura Schummers, who led the research while at Harvard and is now a post-doctoral fellow at the University of British Columbia, says there'south good news for you here as well:
"The optimal spacing window that we found was one to two years after the commitment of one kid until the conception of the next pregnancy," she says. "That's when we found the lowest risk for both mothers and babies." And, she adds, that'southward brusque compared to some previous studies that had suggested the optimal look was between 18 months and upwards to five years.
Past research has institute a clear link between short "interpregnancy intervals" and increased gamble of wellness problems for female parent and babe, including premature birth. Only why? The contend, Schummers says, revolves effectually whether the short interval is a straight biological cause of the risks, or whether information technology information technology is itself a consequence of other forces at work in the mother'south life — for example, a lack of access to wellness care and unintended pregnancies.
Because older women are likelier to program their pregnancies and have amend access to care, Schummers and colleagues hypothesized that those mothers would not incur as much risk as younger women do if they had babies close together.
They found out they were wrong.
"In fact," Schummers says, "we establish that there were risks of adverse infant outcomes for women of all ages.
"The risks to the babies were higher among younger women, which was consistent with the squad's hypothesis. Just risks to the mothers were higher amongst older women — indeed, only older mothers incurred higher risks to their own health by getting significant once again so presently.
Afterward bookkeeping for other factors that could drive these numbers, Schummers says, the stats milk shake out like this:
• For women 35 years or older who conceived just vi months later on a nascency, half-dozen.ii per yard experienced serious illness or injury, including death. Wait xviii months and that risk dropped to 2.6 per per yard. So, modest absolute numbers only a dramatic divergence.
• A "severe adverse babe outcome" includes stillbirth and being born very early or very small. Among women ages 20 to 34, those who conceived after only six months had 20 babies per thousand with those severe outcomes; the adventure drops to fourteen per thousand among those who waited 18 months.
• Amidst women 35 years or older, there were 21 severe infant outcomes per grand amidst those who waited just 6 months; the risk drops to eighteen per thousand among those who waited 18 months.
"This shows you lot both the relationship between pregnancy spacing and the increased run a risk," Schummers says, "merely as well that older women tend to take a college baseline adventure of many of these outcomes at all pregnancy spacing lengths."
The enquiry turned up a like pattern for premature nativity: A short pregnancy interval raises the risk for all women, but peculiarly for younger women. The risk for them dropped from 53 per thousand at a six-month interval to 32 per thousand at an 18-calendar month interval. For women over 35, the take chances dropped from fifty per thousand at six months to 36 per thou after 18 months.
It seems like common sense that a woman's body may need more than six months to fully recover from building a baby and giving birth, but the actual mechanism behind the risks of curt pregnancy intervals is not fully clear.
The leading theory, Schummers says, is that nutrients similar fe or folate could be depleted in the female parent's body. Merely more than research is needed to see if that theory holds in developed countries like the U.s.a. and Canada, or if there are other mechanisms that accept not yet been identified.
For now, she says, her team hopes these new findings tin assist women make decisions within their own personal contexts, and in consultation with their medical teams. The data may be especially helpful for older women, she says, because they more often determine to accept short pregnancy intervals on purpose.
"And and so if you're making that kind of conclusion on purpose," she says, "it'southward easier to say, 'You know, let's wait another three months.' "
