PTSD Nearly Doubles the Risk of Infection

A new study finds that people with post-traumatic stress disorder (PTSD) are 1.8 times as likely to have any infection as those without PTSD, ranging from being 1.3 times as likely to have meningitis, to 1.7 times as likely to have influenza, to 2.7 times as likely to have viral hepatitis.

The Boston University School of Public Health (BUSPH) study is the first to look at the relationship between PTSD and dozens of infection types in a nationwide dataset.

The study is also the first to find that PTSD affects infection risks for men and women differently, having, for example, more of an effect on a woman’s risk of urinary tract infection and a man’s risk of skin infection.

“Our study adds to the growing evidence suggesting that PTSD and chronic severe stress are damaging for physical health,” says BUSPH doctoral candidate Tammy Jiang, who led the study. The findings underscore the public health importance of PTSD prevention and treatment interventions, she says.

For the study, Jiang and a team from BUSPH, Aarhus University Hospital in Denmark, the University of Vermont, and the Emory University Rollins School of Public Health used Danish national records to look at the health histories of every Danish-born Danish citizen who received a PTSD diagnosis from 1995 through 2011, and matched each person with a comparison group of Danes of the same sex and age.

The team then compared the participants’ histories of hospital care for 28 different kinds of infections. After adjusting for other physical and mental health diagnoses and for marriage/registered partnership, the findings show that people with PTSD were 1.8 times as likely to have any infection than those without PTSD, as well as calculating the increased risk for each of the 28 kinds of infection.

Next, the researchers compared men and women with PTSD and found that having PTSD had more of an effect on a woman’s risk for several kinds of infection, most notably urinary tract infection, than on a man’s risk.

Having PTSD also had more of an effect on a man’s risk of certain other kinds of infection, most notably skin infection.

The findings are published in the journal Epidemiology.
