Longer Breastfeeding May Decrease The Risk Of Type 2 Diabetes In Mothers
Breastfeeding for a year was recommended by the American College of Obstetricians and Gynecologists. But an earlier study shows that only 55 percent of the women were found breastfeeding in six months and a just 33 percent of the women in 12 months. An earlier study also shows that the following risks will be lowered in babies with breastfeeding their babies until they reach the age of six months.
An uncontrolled study supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) shows a lower risk of type 2 diabetes in the mother with a longer period of breastfeeding (also known as nursing).
Researchers have conducted an analytical study on 1,238 mothers, aged between 18 and 30 years with an average age of 24 years, both Black and White race and having at least one baby during the study. All of them are without type 2 diabetes at the start of the study. Researchers have used the Coronary Artery Risk Development in Young Adults (CARDIA) study data.
Over a period of 25 years, they found the diagnosis of type 2 diabetes in 182 women. The following table shows the number of new type 2 diabetes patients per year among women and the duration of breastfeeding.
Among the women with gestational diabetes during the pregnancy, the study shows 2.08 percent of the enhanced risk of type 2 diabetes per year in the women who did not breastfeed their baby when compared to the women who breastfeed their baby for at least 12 months.
But among the women without gestational diabetes during the pregnancy, the study shows just 0.48 percent of the risk of type 2 diabetes per year to the women who did not breastfeed their baby when compared to the women who breastfeed their baby for at least 12 months.
The study has found a gradual decrease in the risk of type 2 diabetes with an increased duration in breastfeeding. This biological association is independent of other risk factors for type 2 diabetes such as race, diet, lifestyle, obesity (body mass index. BMI) and gestational diabetes.
This study shows that the mother may get more health benefits from breastfeeding than previously known. The researchers say that a longer period of breastfeeding can lower the future risk of type 2 diabetes, even in the women who have developed gestational diabetes during the pregnancy.
Researchers say that a lactation failure (lactation insufficiency, insufficient milk syndrome or cessation of breastfeeding) due to low milk supply could increase the risk of type 2 diabetes. In experiments with mice models, researchers have found a rapid growth in the pancreatic beta-cells with lactation.
