According to the World Health Organization , it is advisable to waitusing data from more than 4.7 million live births in Brazil, suggests that this recommendation should be individualized, considering factors such as maternal obstetric history.
Most of interpregnancy intervals, ie, the difference between the previous childbirth and the subsequent conception, ranged from 23 to 58 months . Extreme intervals of 120 months occurred in 5.6% and 1.6% of cases, respectively. According to the researcher, the finding may reflect the distinct risk profile of mothers who wait a very long time to conceive again."This group, composed of older women, likely has a higher prevalence of health problems, such as diabetes and, which are known risk factors for having large-for-gestational-age babies," he said. He also highlighted the fact that the study showed that the risk for LGA also increased as the interval between pregnancies grew.
Furthermore, the authors noted that the previous occurrence of adverse outcomes seems to"have a more significant impact on the outcome of the current pregnancy than the interpregnancy interval."
