Investigators recently studied whether modifiable cardiometabolic and lifestyle risk factors affected the prevalence of ruptured or unruptured IA and aSAH using a Mendelian randomization. They included common risk factors, such as high blood pressure and smoking, as well as blood glucose levels, body mass index, cholesterol, chronic inflammation, coffee consumption, physical activity, sleep, type 2 diabetes, and kidney function.

The data showed that higher blood pressure, smoking, and a predisposition to insomnia were all associated with increased risk for both IA and aSAH. Of note, a genetic predisposition for insomnia increased the risk for both outcomes by 24%. Other factors did not appear to be significantly associated with risk for either outcome.
