Individuals infected with herpes simplex virus type 1 (HSV-1) may have an increased risk of developing type 2 diabetes by 50%, according to a report from the Peking Union Medical College. Earlier studies have indicated the hepatitis C virus infection as a risk factor for type 2 diabetes. Yet, there is a chance that infection with other viruses may make individuals more susceptible to the disease as well.
The current study tested 206 participants with type 2 diabetes for HSV-1 infection and a control group of 1360 participants without diabetes. The researchers noted that all of the participants were negative for hepatitis C virus antibodies. The results of the study found that 46% of the patients with diabetes were infected with HSV-1, compared with 36% of the controls. Reporting in Diabetes Care (February 2005), the researchers said that individuals with diabetes comprised 16% of the group with HSV-1 but only 11% of those were free of the virus.
One study linked multiple pregnancies to an increased risk of developing atrial fibrillation later in life, and another investigated the association between premature delivery and cardiovascular disease.
