Diabetes and depression

There is good evidence of a link between diabetes and depression and new research from the Harvard School of Public Health suggests that the link could work in both directions. The researchers studied 65,381 women who were aged between 50 and 75 in 1996. The women filled out a questionnaire about their medical history at the start of the study and every two years thereafter. Over the course of the study 2,844 of the women developed type 2 diabetes and 7,415 developed depression. The women with depression were about 17% more likely to develop diabetes, even after taking into account other risk factors such as physical activity and weight, while the women with diabetes were 29% more likely to develop depression.
