Breastfeeding for me and my health

Mothers who did not breastfeed their children are at significantly higher risk of developing type 2 diabetes later in life than moms who breastfed, reports a study published in the September issue of the American Journal of Medicine

The study included 2,233 women between the ages of 40 and 78 who were members of a large integrated health care delivery organization in California. Strikingly, one of every four mothers who had never breastfed had developed type 2 diabetes. Mothers who had not breastfed were almost twice as likely to develop diabetes as women who had breastfed or women who had never given birth.  These long-term differences were notable even after considering age, race, physical activity and other factors which affect risk of diabetes such as alcohol and tobacco use.   In contrast, mothers who breastfed all of their children were no more likely to develop diabetes than women who never gave birth.  In other words, breastfeeding is part of the way mothers’ bodies recover from pregnancy. When this process is interupted, and an infant is fed something other than it’s mother’s milk, a mother’s body suffers.

While prior studies have shown that the longer a mother breastfeeds the lower her risk of developing diabetes, this study found that even a single month of breastfeeding had marked effects on a mother’s future risk of developing diabetes.  This means that is all the more important that we find ways to support moms’ early efforts to breastfeed, and that we encourage moms to breastfeed for at least their baby’s first month of life.  Hospitals and workplaces that fail to provide this support are jeopardizing the health of both mothers and their children and producing significant costs to our society.   It was recently estimated that if 90% of US families could comply with medical recommendations to breastfeed exclusively for 6 months, the United States would save $13 billion per year and prevent an excess 911 infant deaths.  Unfortunately, only 56 percent of mothers studied reported they had ever breastfed an infant for one or more months.

Mothers who were not able to breastfeed their children may want to discuss with their primary care provider whether dietary changes or increasing physical activity may now be advisable.  Similarly, clinicians need to consider women’s pregnancy and lactation history when advising women about their risk for developing type 2 diabetes in the future.
