Women who have C-sections are no more likely to have children who develop obesity than women who give birth naturally, according to a large study by researchers at Karolinska Institutet in Sweden, published in the journal PLOS Medicine.
The findings contradict several smaller studies that did find an association between C-section deliveries and offspring obesity but did not consider the numerous maternal and prenatal factors that the researchers did in this study.
Cesarean or C-section deliveries have soared in recent years, from 6.7 percent globally in 1990 to around 19.1 percent in 2014, according to earlier reports. The jump has sparked intense research into the long-term consequences of C-section on offspring health, and several studies have linked cesarean deliveries with increased risks for asthma, various allergies and obesity. The association with obesity has, however, mainly been confirmed in smaller studies that were unable to account for a wide array of possible confounders or differentiate between types of C-sections.
