Risk of diabetes raised by spouse having the disease

When Canadian researchers reviewed six articles, covering nearly 75,000 couples, they found spousal history was associated with a 26% increased diabetes risk and an 18% increased risk when adjusted for BMI.

Spouses may share the same environment, diet, physical activity and smoking and drinking habits, the authors said.

Taking a spousal medical history may be as important as family history when assessing a person’s risk of diabetes, they concluded.
