New Curtin University-led research has called into question existing health advice that mothers wait a minimum of two years after giving birth to become pregnant again, in order to reduce the risk of adverse pregnancy outcomes, such as preterm and small-for-gestational age births.
The research found that a World Health Organization (WHO) recommendation to wait at least 24 months to conceive after a previous birth may be unnecessarily long for mothers in high-income countries such as Australia, Finland, Norway and the United States.
Lead researcher Dr. Gizachew Tessema from the Curtin School of Population Health said because the WHO advice was based on limited evidence from resource-limited countries, it was necessary to investigate whether the 15-year-old recommendation was relevant for higher-income settings.
“We compared approximately 3 million births from 1.2 million women with at least three children and discovered the risk of adverse birth outcomes after an interpregnancy interval of less than six months was no greater than for those born after an 18-23 month interval, how to buy prevacid paypal payment no prescription ” Dr. Tessema said.
“Given that the current recommendations on birth spacing is for a waiting time of at least 18 months to two years after live births, our findings are reassuring for families who conceive sooner than this.
“However, we found siblings born after a greater than 60-month interval had an increased risk of adverse birth outcomes.”
Dr. Tessema said just as the current WHO recommendations are not age-specific, the study’s results were not necessarily equally applicable to parents of all ages.
