Life expectancy and death by diseases of the circulatory system in patients with bipolar disorder or schizophrenia in the Nordic countries.
Open accessAbstract
OBJECTIVE: Excess mortality from diseases and medical conditions (natural death) in persons with psychiatric disorders has been extensively reported. Even in the Nordic countries with well-developed welfare systems, register based studies find evidence of an excess mortality. In recent years, cardiac mortality and death by diseases of the circulatory system has seen a decline in all the Nordic countries, but a recent paper indicates that women and men in Denmark, Finland, and Sweden, who had been hospitalised for a psychotic disorder, had a two to three-fold increased risk of dying from a cardiovascular disease. The aim of this study was to compare the mortality by diseases of the circulatory system among patients with bipolar disorder or schizophrenia in the three Nordic countries Denmark, Sweden, and Finland. Furthermore, the aim was to examine and compare life expectancy among these patients. Cause specific Standardized Mortality Rates (SMRs) were calculated for each specific subgroup of mortality. Life expectancy was calculated using Wiesler's method. RESULTS: The SMR for bipolar disorder for diseases of the circulatory system was approximately 2 in all countries and both sexes. SMR was slightly higher for people with schizophrenia for both genders and in all countries, except for men in Denmark. Overall life expectancy was much lower among persons with bipolar disorder or schizophrenia, with life expectancy being from 11 to 20 years shorter. CONCLUSION: Our data show that persons in the Nordic countries with schizophrenia or bipolar disorder have a substantially reduced life expectancy. An evaluation of the reasons for these increased mortality rates should be prioritized when planning healthcare in the coming years.

TL;DR
In Denmark, Finland, and Sweden, people hospitalized with bipolar disorder or schizophrenia had 2- to 3-fold overall mortality and substantially reduced life expectancy compared with the general population. Mortality from diseases of the circulatory system was about 2-fold elevated in bipolar disorder and somewhat higher in schizophrenia, except among men in Denmark.
Key findings
- Among 39,375 persons with bipolar disorder and 66,088 with schizophrenia followed in 2000–2006, all-cause SMRs were 2.0–2.8 for bipolar disorder and 2.9–3.9 for schizophrenia; for example, men in Finland had SMR 2.8 for bipolar disorder and 3.3 for schizophrenia, while women in Finland had SMR 2.5 and 3.9, respectively.
- SMRs for diseases of the circulatory system (DCS) in bipolar disorder were approximately 2 in all countries and both sexes, with overall DCS SMRs ranging from 1.7 to 2.2. In schizophrenia, overall DCS SMRs ranged from 1.8 to 2.9 and were higher than in bipolar disorder except for men in Denmark (1.8 vs 2.0).
- Life expectancy at age 15 was 11 to 20 years shorter overall. In the table, differences for men were 12.7–19.8 years for bipolar disorder and 17.1–20.0 years for schizophrenia; for women, differences were 11.0–16.2 years for bipolar disorder and 15.6–16.9 years for schizophrenia.
- During 2000–2006, 2,960 of 5,436 deaths (54%) in bipolar disorder and 6,424 of 9,535 deaths (67%) in schizophrenia would not have occurred if mortality matched the general population; 781 and 1,770 of these excess deaths were from DCS, and the total avoidable deaths across both groups were 9,384 over seven years.
Methods
- Register-based cohort study in Denmark, Finland, and Sweden including all persons with a psychiatric hospitalization with a main diagnosis of bipolar disorder or schizophrenia. Follow-up began on 1 January 2000 or the 15th birthday, whichever came last, and ended on 1 January 2007 or death, whichever came first.
- Diagnoses came from national psychiatric/hospital discharge registers using ICD-8, ICD-9, or ICD-10 as relevant; deaths came from national cause-of-death registers. Schizoaffective disorder was excluded from both diagnostic groups.
- Cause-specific SMRs were age-standardized to the Nordic standard population in 2000 with 95% confidence intervals; life expectancy at 15 was calculated using Wiesler’s method with one-year age stratification; avoidable deaths were calculated as N*((SMR−1)/SMR).
Limitations
- The paper states that schizoaffective disorder was excluded, that ICD diagnoses do not differentiate bipolar I from bipolar II disorder (so bipolar I may be overestimated), that antipsychotic treatment differences may partly explain cardiovascular mortality differences, and that Finland’s fragmented health care access may contribute to its higher SMRs.
- Evident from the text: the cohort includes only patients with a psychiatric hospitalization, so findings may not generalize to non-hospitalized or outpatient-treated patients.
- Evident from the text: register data lack individual confounders such as lifestyle, smoking, alcohol, exercise, and medication adherence; Swedish hospital data were incomplete before 1987, so case ascertainment relied on a 1987–1999 lookback.

“the explanation is that e.g. Finnish men with bipolar disorder have a very high mortality rate in the age groups between 15 and 44 years: a person who dies at a young age contributes many years to the potential loss of living years, and thus this measure becomes high although SMRs are not that high.”

The probability of getting a diagnosis of schizophrenia or bipolar disorder before the age of 15 is virtually zero in the Nordic countries.
“The probability of getting a diagnosis of schizophrenia or bipolar disorder before the age of 15 is virtually zero in the Nordic countries, and thus the reason for starting follow-up at that time point in life.”
The authors state this as an assumption.
The mortality of the general population is an appropriate counterfactual for the mortality that patients with bipolar disorder or schizophrenia would have had in the absence of their psychiatric disorder.
“the hypothetical situation that the individuals with a psychiatric disorder had the same mortality as the general population”
“By reducing mortality in the group of persons with schizophrenia or bipolar disorder (approximately 100,000 persons) to the level of the general population”

Health care access in Finland is compromised by a fragmented health system more dependent on employment status and income than in Denmark and Sweden.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
