Childhood obesity and cesarean delivery rates have skyrocketed over the last few decades, and intriguing new research suggests the two might be related.
Birth by C-section was associated with a two-fold increase in obesity at age 3 in the study by investigators from Harvard Medical School and Harvard School of Public Health.
Surgical delivery has recently been linked to an increased risk for allergy and asthma in children, but research examining the impact of C-section delivery on weight in childhood has been mixed.

In the newly published study, investigators followed 1,255 children from birth until after their third birthdays, during which time 16% of children delivered by C-section became obese, compared to 7.5% of children delivered vaginally.
