According to an American study published on October 29 and relayed by the Physician's Daily, the ideal interval between the birth of a child and the conception of the next is between 12 and 24 months, whatever the age of the child. wife.
A panel of 123,122 women was constituted between 2004 and 2014 in British Columbia (Canada), corresponding to 148,544 pregnancies. Of these pregnancies, 83.4% involved women aged 20 to 34, 11.8% of over 35s and 4.8% of those under 20 years of age.
For each age group, the risks of pregnancy intervals of 3, 6, 9 and 12 months were compared at the 18-month interval.
"Our research has revealed increased risks for both mother and infant when pregnancies are close, especially for women over 35," said study director Laura Schummers. "The results for older women are particularly important because they tend to space their pregnancies more closely and often do so intentionally."
A risk for the mother
For example, the risk of maternal mortality or severe morbidity (admission to the intensive care unit, organ failure, etc.) was 2.39 times higher for a 6-month interval than for an 18-month interval in women with this age. For women aged 20 to 34, no difference was found between 6 and 18 months.
A risk for the baby
In addition, "we have found risks for the baby in women aged 20 to 34 and 35 years and over." The risk to the baby (death at birth, premature birth, low birth weight, etc.) is however greater for women aged 20 to 34: it is 1.42 times higher at 6 than at 18 months. For people over 35, the risk is 1.15 times higher.
A risk of premature labor
Taking into account the risk of spontaneous premature birth also shows a higher risk in the 20-34 age group, with a risk 1.65 times higher at 6 than at 18 months (against 1.40 times at 35 years old). and more). "The number of women under 20 was too small for us to make meaningful comparisons," said Laura Schummers.
This study suggests that the optimal delay between two pregnancies is 12 to 24 months. "Beyond that, the risks are starting to increase again, but as our study focused on short intervals between two pregnancies, the risks badociated with longer intervals were not presented," the scientist said.
More late pregnancies
In France, over the last thirty years, the number of late pregnancies has increased. According to INSEE statistics, 17.5% of babies born in 2004 have a mother aged 35 and over (and 3.3% a mother over forty), whereas they were 14% in 1995 and 8% in 1980.
