The authors also found that antibiotic use was associated with even higher risk for mental illness. This connection is thought to be, in part, because antibiotics affect bacteria in the intestinal microbiome.
The study — which supports emerging theories about the functional interaction between infection, the gut microbiome and mental illness — is one of close to 50 papers published using data from the Danish Psychiatric Central Research Register since the latter half of 2018.
This registry tracks, for the first time, the clinical data of more than one million people — in this case, data from 1995 onwards on Danes who were treated for mental illness over their first 17 years of life, either in a hospital or as outpatients.
