Many older first-time moms face a dilemma when it comes to baby No. 2. The clock is ticking louder than always. Just doctors propose waiting at to the lowest degree a twelvemonth and a one-half later on giving nascency before conceiving over again.

This is the standard advice, based on multiple studies and public health guidelines. But deciding when to effort again can be a difficult decision — weighing medical risk against infertility adventure. Now there are some new data points to factor in. A paper published Monday in the journal JAMA Internal Medicine analyzed medical records from near 150,000 Canadian pregnancies to tease out how a female parent'due south historic period 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 kid. But epidemiologist Laura Schummers, who led the research while at Harvard and is at present a post-doctoral young man at the University of British Columbia, says there's practiced news for you lot here as well:

"The optimal spacing window that we found was ane to two years after the delivery of 1 child until the conception of the adjacent pregnancy," she says. "That'southward when we plant the lowest risk for both mothers and babies." And, she adds, that'due south brusque compared to some previous studies that had suggested the optimal wait was between eighteen months and upward to five years.

Past inquiry has constitute a clear link betwixt short "interpregnancy intervals" and increased adventure of health problems for female parent and baby, including premature birth. But why? The debate, Schummers says, revolves effectually whether the short interval is a direct biological cause of the risks, or whether information technology information technology is itself a issue of other forces at work in the mother's life — for case, a lack of access to health care and unintended pregnancies.

Because older women are likelier to plan their pregnancies and have better access to intendance, Schummers and colleagues hypothesized that those mothers would not incur as much take chances every bit younger women practise if they had babies close together.

They found out they were wrong.

"In fact," Schummers says, "we found that in that location were risks of agin infant outcomes for women of all ages.

"The risks to the babies were college amidst younger women, which was consistent with the team's hypothesis. But risks to the mothers were higher amidst older women — indeed, but older mothers incurred higher risks to their own health past getting pregnant once more so before long.

After accounting for other factors that could drive these numbers, Schummers says, the stats shake out similar this:

• For women 35 years or older who conceived simply six months after a birth, vi.2 per chiliad experienced serious illness or injury, including death. Look 18 months and that risk dropped to 2.6 per per yard. Then, minor absolute numbers only a dramatic divergence.

• A "astringent adverse infant upshot" includes stillbirth and being born very early on or very pocket-sized. Amidst women ages 20 to 34, those who conceived later on only half dozen months had 20 babies per chiliad with those severe outcomes; the risk drops to fourteen per grand amid those who waited eighteen months.

• Amidst women 35 years or older, there were 21 severe infant outcomes per g among those who waited but 6 months; the chance drops to 18 per thousand among those who waited xviii months.

"This shows you both the relationship betwixt pregnancy spacing and the increased risk," Schummers says, "only likewise that older women tend to have a college baseline run a risk of many of these outcomes at all pregnancy spacing lengths."

The inquiry turned up a similar pattern for premature birth: A short pregnancy interval raises the take chances for all women, only specially for younger women. The gamble for them dropped from 53 per thousand at a six-month interval to 32 per k at an eighteen-month interval. For women over 35, the risk dropped from fifty per thousand at half dozen months to 36 per thousand after 18 months.

It seems like common sense that a adult female's body may need more six months to fully recover from building a baby and giving birth, but the actual machinery behind the risks of short pregnancy intervals is not fully clear.

The leading theory, Schummers says, is that nutrients like iron or folate could be depleted in the mother'south torso. Simply more than research is needed to encounter if that theory holds in developed countries like the United States 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 help women brand decisions within their own personal contexts, and in consultation with their medical teams. The data may be particularly helpful for older women, she says, because they more often determine to accept brusque pregnancy intervals on purpose.

"And so if yous're making that kind of decision on purpose," she says, "it'southward easier to say, 'You know, allow's wait some other iii months.' "
