Australians with schizophrenia die 25 years earlier than the general population, according to a new study.
The gap in life-expectancy has been labelled a "preventable tragedy" and led to calls for urgent national action.
A research paper by researchers at the University of Sydney and published in the Medical Journal of Australia, shows people with this mental illness mainly die because of poor heart health.
"People with schizophrenia and psychosis die early in life mainly from heart attacks, heart disease, and strokes due to untreated hypertension and high cholesterol, and high rates of obesity and smoking," said lead author, psychiatrist Professor Tim Lambert of the University of Sydney Collaborative Centre for Cardiometabolic Health in Psychosis (ccCHiP).
Prof Lambert says a lack of co-ordinated care between hospitals, community mental health services, GPs and other primary health care professionals is to blame.

The facts on schizophrenia and heart health.
