Non-breastfeeding moms risk diabetes

Mothers who did not breastfeed their children have significantly higher rates of type 2 diabetes later in life than moms who breastfed, report University of Pittsburgh, US, researchers in a study published in the American Journal of Medicine.

"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 realise that breastfeeding also reduces mothers' risk of developing the disease later in life by decreasing maternal belly fat."

The study

The study included 2,233 women between the ages of 40 and 78. Overall, 56% of mothers reported they had breastfed an infant for at least one month. 27% 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. In contrast, 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," said Schwarz. "Clinicians need to consider women's pregnancy and lactation history when advising women about their risk for developing type 2 diabetes." - (EurekAlert, August 2010)
