A study of more than 100,000 persons with bipolar disorder or schizophrenia from three Nordic countries found that life expectancy was 12 to 20 years reduced for the men and 11 to 17 years reduced for the women, compared to the general population. The main reasons for the excess mortality were an unhealthy lifestyle in terms of their diet, smoking, alcohol use and exercise. A higher mortality rate for individuals with schizophrenia compared to those with bipolar was seen as possibly due to the increased use of antipsychotic medications in the schizophrenia group. Results appear online in PL0S ONE.
