TUESDAY, April 14, 2020 (HealthDay News) — Women born by cesarean delivery may have a higher risk for being obese and developing type 2 diabetes during adult life than women born by vaginal delivery, according to a study published online April 13 in JAMA Network Open<\/i>.<\/p>\n
Jorge E. Chavarro, M.D., Sc.D., from the Harvard T.H. Chan School of Public Health in Boston, and colleagues compared the incidence of obesity and type 2 diabetes between cesarean delivery and vaginal delivery births among 33,226 women (aged 24 to 66 years) participating in the Nurses’ Health Study II (born between 1946 and 1964), with follow-up through 2015.<\/p>\n
The researchers found that 3.3 percent of participants were born by cesarean delivery, and after 1,913,978 person-years of follow-up, 36.6 percent were obese and 6.1 percent received a diagnosis of type 2 diabetes. Participants born by cesarean delivery were more likely to be classified as obese (adjusted relative risk, 1.11) and to have received a diagnosis of type 2 diabetes (adjusted relative risk, 1.46) versus women born via vaginal delivery. This association remained significant after adjusting for participants’ body mass index (adjusted relative risk, 1.34).<\/p>\n
“Whether these findings are applicable to men or to individuals born today, when cesarean delivery rates are substantially higher, is uncertain,” the authors write.<\/p>\n
