A study by University of Pittsburgh researchers has claimed that breastfeeding protects mothers from developing type 2 diabetes later in life.
"We have seen dramatic increases in the prevalence of type 2 diabetes over the last century," said Dr. Eleanor Bimla Schwarz, assistant professor of medicine, epidemiology, and obstetrics, gynecology and reproductive sciences at the University of Pittsburgh.
"Diet and exercise are widely known to impact the risk of type 2 diabetes, but few people realize that breastfeeding also reduces mothers' risk of developing the disease later in life by decreasing maternal belly fat," he added.
Overall, 56 percent of mothers reported they had breastfed an infant for at least one month.
Twenty-seven percent of mothers who did not breastfeed developed type 2 diabetes and were almost twice as likely to develop the disease as women who had breastfed or never given birth.
On the other hand, mothers who breastfed all of their children were no more likely to develop diabetes than women who never gave birth.
These long-term differences were notable even after considering age, race, physical activity and tobacco and alcohol use.
"Our study provides another good reason to encourage women to breastfeed their infants, at least for the infant's first month of life. Clinicians need to consider women's pregnancy and lactation history when advising women about their risk for developing type 2 diabetes," said Schwarz.
The study has been published in the September issue of the American Journal of Medicine.
