Of the vaginally born children in the study, 13.2% had a food allergy. The researchers found that out of the 30% of children born by C-section, 12.7% had a food allergy during infancy. It also linked data with the Victorian Perinatal Data Collection. The present study tracked birth factor data on infants from the HealthNuts study. For instance, doctors often give mothers antibiotics during C-sections, which may affect the composition of the baby’s gut bacteria. Fisher mentioned that many factors contribute to a newborn’s microbiome before, during, and just after birth. I think this study was very interesting to let us clinicians know we don’t have to necessarily rely on their birth history to give us clues.”ĭr. “It is interesting as we are learning more about this microbiome in the gut and how it can affect the babies. Fisher said that a C-section versus vaginal birth has not been a major consideration for her in dealing with children’s food allergies. Danelle Fisher, pediatrician and Chair of Pediatrics at Providence Saint John’s Health Center in Santa Monica, CA, who was not involved in the research, about the implications of these findings.ĭr. Scientists have supposed that this might interfere with the proper development of a newborn’s immune system. The study appears in the Journal of Allergy and Clinical Immunology: In Practice.Ĭhildren delivered by C-section bypass the process of being exposed to beneficial bacteria in the birth canal. They said that their findings “may be useful for caregivers when considering the risks and benefits of cesarean delivery, and provide reassurance for mothers who require such intervention that there is little evidence that their infants are likely to be at a substantially increased risk of food allergy.” Now, new research offers compelling evidence that may ease the worries of expecting parents.Īfter studying data on over 2,000 infants, researchers at the Murdoch Children’s Research Institute in Australia concluded that the method of delivery has no significant impact on food allergy onset. Scientists have long assumed that cesarean delivery could make newborns more likely to develop allergic disorders in infancy. This condition affects an estimated 5% of children in the United States and is becoming more prevalent. The scientists also found that 30% of peanut allergies and 90% of egg allergies clear up by age 6.įood allergies can cause a person’s immune system to overreact to certain foods, triggering mild to life threatening symptoms.
Australian researchers say that elective or emergency C-sections that took place before or after labor started, do not affect the likelihood of developing food allergies compared to vaginal births.A recent study found that cesarean ( C-section) delivery does not increase the risk of food allergies in infants in the first year of their lives.Share on Pinterest Compared to vaginal birth, cesarean delivery has not been linked to an increased risk of childhood allergies.
