Type 2 Diabetes Risk Differs By Blood Type

A new study done by researchers in France at the Center for Research in Epidemiology and Population Health at the Gustave Roussy Institute has indicated the risk of developing diabetes can differ by blood type. The researchers looked at data from over 82,000 women. The study which included nearly 100,000 female teachers began in 1990.


The data was collected by having the women complete questionnaires about their health. The women’s risks of developing diabetes were able assessed by Rhesus factor in addition to the blood type. Each of these groups were them compared to the blood group O negative. The analysis of the data showed that women that have blood type A are more likely to develop diabetes than women that have blood type O. However, individuals with blood type B are more likely to develop type 2 diabetes.


There were no differences in risk for people that were Rhesus positive versus Rhesus negative. Women that have the blood type B+ were more likely to develop diabetes than people with blood type O-. Women with the blood type AB+ are more likely to develop diabetes at a rate of 26 percent. People with blood type A- had a 22 percent higher risk. Those individuals with blood type A+ were at an increased risk of 17 percent.


The findings for blood types O-, B-, and AB- are not statistically significant. Although there were differences in the risks according to blood type, the researchers say that there is not any information that suggests that the risks by blood type differ between the sexes. In addition, this new research also indicates that the risks for Type 2 diabetes may go far beyond the commonly associated risks, such as obesity.
