These women were also less likely to have a cesarean delivery, have a premature delivery or have a low birth weight baby, the researchers noted. This association was not due to social and personal factors or by other problems in pregnancy including smoking, they added.
And delaying getting pregnant after a miscarriage carries some risks, they said.
Putting off pregnancy, particularly in developed countries, can be problematic, researchers noted. "Women over 35 are more likely to experience difficulties in conceiving, and women aged 40 years have a 30 percent chance of miscarriage, which rises to 50 percent in those aged 45 years or more. Any delay in attempting conception could further decrease their chance of a healthy baby," they wrote.
Julia Shelley, an associate professor from the School of Health and Social Development at Deakin University in Melbourne, Australia, and author of an accompanying journal editorial, said the study did not conclusively answer the question of when the best time was to get pregnant after a miscarriage.
"In research such as this study, it is not possible to tell whether the intervals between pregnancies were deliberately chosen, or were accidental or involuntary," Shelley said. "Consequently, we cannot really tell whether pregnancies conceived very soon after a miscarriage really do have better outcomes, or whether women [and couples] who conceive quickly following a miscarriage have better outcomes in a subsequent pregnancy than couples who take longer to conceive."
"I think we can say that the study suggests that there is no harm in conceiving again immediately following a miscarriage," Shelley said.
But, she added, "I don't think the study provides good evidence that pregnancies conceived six to 12 months following a miscarriage will have poorer outcomes than those conceived more quickly. For example, the higher rate of pregnancy terminations in pregnancies conceived between 6
