Mortality trends in external causes of death in people with mental health disorders in Sweden, 1987-2010.

AIM: We investigated mortality from external causes in Swedish people who had been hospitalised with a severe mental disorder. METHODS: Hospitalisations in people aged 15 years or older admitted to hospital with a main diagnosis of schizophrenia, bipolar mood disorder or unipolar mood disorder between 1987 and 2010 were linked to their causes of death. RESULTS: The mortality rate from all external causes was 20-fold higher in those with unipolar mood disorder, 15-fold higher in those with bipolar disorder and 12-fold higher in those with schizophrenia than in the general population. Over the study periods, the mortality rate declined more for people with unipolar mood disorder (-35%) and schizophrenia (-29%) than the total population (-25%) and those with bipolar mood disorder (-15%). The suicide rate declined most for those with unipolar mood disorder and schizophrenia (-42% for both) and less for the general population (-37%) and those with bipolar mood disorder (-21%). For external causes other than suicide, the mortality rate declined in the general population (-17%) but increased in people with schizophrenia (14%), bipolar mood disorder (30%) and unipolar mood disorder (52%). CONCLUSIONS: People with mental disorders have high but declining excess mortality from suicide. Mortality from other external causes has increased, as has the gap in mortality rates between psychiatric patients and the general population.

Lithium treatment and cancer incidence in bipolar disorder.

OBJECTIVES: To investigate whether there is an increased risk of cancer associated with lithium treatment in patients with bipolar disorder compared to the general population. METHODS: A nationwide Swedish register study of incidence rate ratios (IRRs) of total cancer and site-specific cancer in the 50-84-year age range was carried out in patients with bipolar disorder (n = 5,442) with and without lithium treatment from July 2005 to December 2009 compared to the general population using linked information from The Swedish Cancer Register, The National Patient Register, and The Drug Prescription Register. RESULTS: The overall cancer risk was not increased in patients with bipolar disorder. There was no difference in risk of unspecified cancer, neither in patients with lithium treatment compared to the general population [IRR = 1.04, 95% confidence interval (CI): 0.89-1.23] nor in patients with bipolar disorder without lithium treatment compared to the general population (IRR = 1.03, 95% CI: 0.89-1.19). The cancer risk was significantly increased in patients with bipolar disorder without lithium treatment in the digestive organs (IRR = 1.47, 95% CI: 1.12-1.93), in the respiratory system and intrathoracic organs (IRR = 1.72, 95% CI: 1.11-2.66), and in the endocrine glands and related structures (IRR = 2.60, 95% CI: 1.24-5.47), but in patients with bipolar disorder with lithium treatment, there was no significantly increased cancer risk compared to the general population. CONCLUSIONS: Bipolar disorder was not associated with increased cancer incidence and neither was lithium treatment in these patients. Specifically, there was an increased risk of respiratory, gastrointestinal, and endocrine cancer in patients with bipolar disorder without lithium treatment.

Suicide risk and antipsychotic side effects in schizophrenia: nested case-control study.

OBJECTIVE: This study explores suicide risk in schizophrenia in relation to side effects from antipsychotic medication. METHODS: Among patients with a first clinical discharge diagnosis of schizophrenia or schizoaffective disorder in Stockholm County between 1984 and 2000 (n = 4000), those who died by suicide within 5 years from diagnosis were defined as cases (n = 84; 54% male). For each case, one individually matched control was identified from the same population. Information on antipsychotic side effects, including extrapyramidal symptoms (EPS) and akathisia, as well as prescriptions of anticholinergic medication, was retrieved from clinical records in a blinded fashion. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) of the association between suicide and side effects as well as anticholinergic medication were estimated using conditional logistic regression. RESULTS: A lower suicide risk was found in patients with a history of EPS (aOR 0.33, 95% CI 0.12-0.94). There was no statistically significant association between akathisia or anticholinergic medication use and the suicide risk. CONCLUSIONS: A lower suicide risk identified among patients with EPS could potentially reflect higher antipsychotic adherence, exposure to higher dosage, or polypharmacy among these patients.

Mortality trends in cardiovascular causes in schizophrenia, bipolar and unipolar mood disorder in Sweden 1987-2010.

INTRODUCTION: People with severe mental illness have increased risk for premature mortality and thus a shorter life expectancy. Relative death rates are used to show the excess mortality among patients with mental health disorder but cannot be used for the comparisons by country, region and time. METHODS: A population-based register study including all Swedish patients in adult psychiatry admitted to hospital with a main diagnosis of schizophrenia, bipolar or unipolar mood disorder in 1987-2010 (614 035 person-years). Mortality rates adjusted for age, sex and period were calculated using direct standardization methods with the 2010 Swedish population as standard. Data on all residents aged 15 years or older were used as the comparison group. RESULTS: Patients with severe mental health disorders had a 3-fold mortality compared to general population. All-cause mortality decreased by 9% for people with bipolar mood disorder and by 26-27% for people with schizophrenia or unipolar mood disorder, while the decline in the general population was 30%. Also mortality from diseases of the circulatory system declined less for people with severe mental disorder (-35% to - 42%) than for general population (-49%). The pattern was similar for other cardiovascular deaths excluding cerebrovascular deaths for which the rate declined among people with schizophrenia (-30%) and unipolar mood disorder (-41%), unlike for people with bipolar mood disorder (-3%). CONCLUSIONS: People with mental health disorder have still elevated mortality. The mortality declined faster for general population than for psychiatric patients. More detailed analysis is needed to reveal causes-of-death with largest possibilities for improvement.

Association between history of psychosis and cardiovascular disease in bipolar disorder.

OBJECTIVES: To determine whether clinical features of bipolar disorder, such as history of psychosis, and cardiovascular disease (CVD) risk factors contribute to a higher risk of CVD among patients with bipolar disorder. METHODS: This cross-sectional study included a sample of 988 patients with bipolar I or bipolar II disorder or schizoaffective bipolar type confirmed by the Structured Clinical Interview for DSM-IV-TR disorders (SCID). Medical comorbidity burden was quantified utilizing the Cumulative Illness Severity Rating Scale (CIRS). This 13-item organ-based scale includes cardiac disease severity quantification. Confirmed by medical record review, patients who scored 1 (current mild or past significant problem) or higher in the cardiac item were compared by logistic regression to patients who scored 0 (no impairment), adjusting for CVD risk factors that were selected using a backwards stepwise approach or were obtained from the literature. RESULTS: In a multivariate model, age [odds ratio (OR) = 3.03, 95% confidence interval (CI): 1.66-5.54, p < 0.0001], hypertension (OR = 2.43, 95% CI: 1.69-3.55, p < 0.0001), and history of psychosis (OR = 1.48, 95% CI: 1.03-2.13, p = 0.03) were associated with CVD. When CVD risk factors from the literature were added to the analysis, age (OR = 3.19, 95% CI: 1.67-6.10, p = 0.0005) and hypertension (OR = 2.46, 95% CI: 1.61-3.76, p < 0.01) remained significant, with psychosis being at the trend level (OR = 1.43, 95% CI: 0.96-2.13, p = 0.08). CONCLUSIONS: The phenotype of psychotic bipolar disorder may reflect higher illness severity with associated cardiac comorbidity. Further studies are encouraged to clarify the effect of the disease burden (i.e., depression), lifestyle, and treatment interventions (i.e., atypical antipsychotics) on this risk association.

Risperidone metabolic ratio as a biomarker of individual CYP2D6 genotype in schizophrenic patients.

PURPOSE: The purpose of the present study was to investigate the predictive value of the risperidone metabolic ratio for the individual CYP2D6 genotype. METHODS: The determination of risperidone, 9-hydroxyrisperidone, and CYP2D6 genotype was performed in 89 schizophrenic patients. The receiver operator characteristic (ROC) method and the area under the ROC curve (AUC) were used to illustrate the predictive value of risperidone metabolic ratio for the individual CYP2D6 genotype. The area under the ROC curve (AUC) was used as a global measure of this predictive value. To evaluate the proposed cutoff levels of >1 and <0.1 to identify individuals with a poor or ultrarapid CYP2D6 genotype the sensitivity, specificity, positive predictive value and negative predictive were calculated. RESULTS: The area under the ROC curve (AUC) for poor and ultrarapid metabolisers was 0.85 and 0.86, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of a risperidone/9-OH-risperidone ratio >1 to CYP2D6 poor metaboliser genotype were 75 %, 95 %, 60 % and 97 %, respectively. The corresponding measures for a metabolic ratio < 0.1 to predict ultrarapid metabolisers were 80 %, 77 %, 18 % and 98 %. CONCLUSIONS: A metabolic ratio > 1 or < 0.1 may be a useful therapeutic biomarker to recommend CYP2D6 genetic testing to guide the present or future treatment of patients in need of psychotropic drugs.

Psychotic disorder is an independent risk factor for increased fasting glucose and waist circumference.

BACKGROUND: Psychosis is associated with excess cardiovascular morbidity and mortality. AIMS: To determine the prevalence of cardiovascular risk factors in patients with psychotic disorders compared with the population. METHODS: 731 consecutive patients with psychosis recruited from psychiatric outpatient clinics in Stockholm County, Sweden, were compared with 5580 individuals from a population study performed in the same area. The main outcome measures were waist circumference, body mass index (BMI) and fasting glucose. RESULTS: Mean waist circumference in patients vs. controls was for males 106 and 94 cm, respectively, and for females 97 and 85 cm, respectively (P < 0.001); mean fasting glucose in patients vs. controls was for males 5.8 and 5.2 mmol/l, respectively, and for females 5.6 and 4.8 mmol/l, respectively (P < 0.001). Comparisons were controlled for differences in age and family history of diabetes. Increased waist circumference was more common in psychotic patients compared with controls (OR = 3.99; 95% CI 3.09-5.15), controlling for fasting insulin, differences in gender, blood pressure, fasting glucose, family history of diabetes, age and tobacco use. Increased fasting blood glucose was also more common in psychotic patients (OR = 2.41; 95% CI 1.84-3.14) controlling for the same factors with the exception of fasting glucose and with the addition of increased waist circumference. CONCLUSION: Our study shows that the psychosis illness per se can be considered as a cardiovascular risk factor, independent of the traditional risk factors such as age and smoking.

Epigenetic aberrations in leukocytes of patients with schizophrenia: association of global DNA methylation with antipsychotic drug treatment and disease onset.

Even though schizophrenia has a strong hereditary component, departures from simple genetic transmission are prominent. DNA methylation has emerged as an epigenetic explanatory candidate of schizophrenia's nonmendelian characteristics. To investigate this assumption, we examined genome-wide (global) and gene-specific DNA methylation levels, which are associated with genomic stability and gene expression activity, respectively. Analyses were conducted using DNA from leukocytes of patients with schizophrenia and controls. Global methylation results revealed a highly significant hypomethylation in patients with schizophrenia (P<2.0×10(-6)) and linear regression among patients generated a model in which antipsychotic treatment and disease onset explained 11% of the global methylation variance (adjusted R(2)=0.11, ANOVA P<0.001). Specifically, haloperidol was associated with higher ("control-like") methylation (P=0.001), and early onset (a putative marker of schizophrenia severity) was associated with lower methylation (P=0.002). With regard to the gene-specific methylation analyses, and in accordance with the dopamine hypothesis of psychosis, we found that the analyzed region of S-COMT was hypermethylated in patients with schizophrenia (P=0.004). In summary, these data support the notion of a dysregulated epigenome in schizophrenia, which, at least globally, is more pronounced in early-onset patients and can be partly rescued by antipsychotic medication. In addition, blood DNA-methylation signatures show promise of serving as a schizophrenia biomarker in the future.

Multi-country rapid adverse drug event assessment: the Asian Pharmacoepidemiology Network (AsPEN) antipsychotic and acute hyperglycaemia study.

PURPOSE: To undertake a multi-country study to investigate the risk of acute hyperglycaemia with antipsychotic use. METHODS: Using a distributed network model with a common minimal data set, we performed a prescription sequence symmetry analysis (PSSA) to investigate the risk of acute hyperglycaemia associated with antipsychotic initiation. Incident insulin prescriptions were used as a proxy indicator of acute hyperglycaemia. Participating countries and population datasets included Australia (300,000 persons), Japan I (300,000 persons), Japan II (200,000 persons), Korea (53 million persons) Taiwan (1 million persons), Sweden (9 million persons), USA-Public (87 million persons) and USA-Private (47 million persons). RESULTS: Olanzapine showed a trend towards increased risk in most databases, with a significant association observed in the USA-Public database (Adjusted sequence ratio (ASR) = 1.14; 95% Confidence Interval (CI) 1.10-1.17) and Sweden (ASR = 1.53; 95% CI 1.13-2.06). Null or negative associations were observed for haloperidol, quetiapine and risperidone. CONCLUSION: Acute hyperglycaemia appears to be associated with olanzapine use, however, this effect was only observed in two large databases. Despite different patterns of utilization of both antipsychotics and insulin, PSSA analysis results for individual antipsychotic medicines were qualitatively similar across most countries. PSSA, used in conjunction with existing methods, may provide a simple and timely method further supporting multi-national drug safety monitoring.

Patterns in mortality among people with severe mental disorders across birth cohorts: a register-based study of Denmark and Finland in 1982-2006.

BACKGROUND: Mortality among patients with mental disorders is higher than in general population. By using national longitudinal registers, we studied mortality changes and excess mortality across birth cohorts among people with severe mental disorders in Denmark and Finland. METHODS: A cohort of all patients admitted with a psychiatric disorder in 1982-2006 was followed until death or 31 December 2006. Total mortality rates were calculated for five-year birth cohorts from 1918-1922 until 1983-1987 for people with mental disorder and compared to the mortality rates among the general population. RESULTS: Mortality among patients with severe mental disorders declined, but patients with mental disorders had a higher mortality than general population in all birth cohorts in both countries. We observed two exceptions to the declining mortality differences. First, the excess mortality stagnated among Finnish men born in 1963-1987, and remained five to six times higher than at ages 15-24 years in general. Second, the excess mortality stagnated for Danish and Finnish women born in 1933-1957, and remained six-fold in Denmark and Finland at ages 45-49 years and seven-fold in Denmark at ages 40-44 years compared to general population. CONCLUSIONS: The mortality gap between people with severe mental disorders and the general population decreased, but there was no improvement for young Finnish men with mental disorders. The Finnish recession in the early 1990s may have adversely affected mortality of adolescent and young adult men with mental disorders. Among women born 1933-1957, the lack of improvement may reflect adverse effects of the era of extensive hospitalisation of people with mental disorders in both countries.

High prevalence of diagnosis of diabetes, depression, anxiety, hypertension, asthma and COPD in the total population of Stockholm, Sweden - a challenge for public health.

BACKGROUND: There is limited knowledge on the prevalence of disease in total populations. Such studies have historically been difficult to conduct but the development of health data registers has facilitated large-scale studies on recorded diagnoses in entire regions. The aim of this study was to analyze the prevalence of diagnosis of six common diseases in the Swedish capital region. METHODS: The study population included all living persons who resided in Stockholm County, Sweden, on December 31st 2011 (N=2 093 717). Information on all consultations between 2007 and 2011 was obtained from primary health care, specialist outpatient care and inpatient care. Prevalence was defined as the proportion of individuals with a recorded diagnosis of diabetes, depression, anxiety disorders, hypertension, asthma and chronic obstructive pulmonary disease during the five year period, respectively. Analyses were done by age and gender. RESULTS: Hypertension had the highest five-year prevalence (12.2%), followed by depression (6.6%), diabetes mellitus (6.2%), asthma (5.9%), anxiety disorders/phobia (4.8%), and COPD (1.8%). Diabetes was more common in men (5.3% of women and 7.1% of men) while depression (8.7% in women and 4.4% in men) and anxiety (6.3% in women and 3.4% in men) were considerably more common in women. Smaller gender differences were also found for hypertension (13.0% in women and 11.4% in men), asthma (6.4% in women and 5.4% in men) and COPD (2.1% in women and 1.6% in men). Diabetes, hypertension and COPD increased markedly with age, whereas anxiety, depression and asthma were fairly constant in individuals above 18 years. During one year of observation, more than half of all patients had only been diagnosed in primary health care, with hypertension being the diagnosis with the largest proportion of patients only identified in primary health care (70.6%). CONCLUSION: The prevalence of common diseases in the population can be estimated by combining data gathered during consecutive years from primary care, specialist outpatient care and inpatient care. However, accuracy of disease prevalence is highly dependent on the quality of the data. The high prevalence of the six diagnoses analysed in this study calls for preventive action to minimize suffering and costs to society.

Symptoms and treatment of bipolar patients in Sweden.

OBJECTIVE: The objective of the study was to investigate affective symptoms and pharmacological treatment in bipolar I disorder patients, and to test whether self-rated symptoms could predict hospital admissions during a 12-month follow-up period. METHODS: A total of 231 outpatients with clinical bipolar I disorder were recruited. The clinical diagnoses were reassessed by a semi-structured interview. Twenty-four patients (10%) was reclassified as bipolar disorder type II or schizoaffective disorder (bipolar type). Medication status was recorded and symptoms were assessed with the self-rating scale AS-18. Patients were prospectively followed for 12 months and hospitalizations during that time were recorded. RESULTS: More than half (60%) rated themselves as normothymic. Mixed affective symptoms were more common than either depressive or manic/hypomanic symptoms. The admission rate during 1 year of follow-up was 13% (95% C.I. 8-17%). Patients which at baseline rated themselves high in either mania or in depression had a significantly increased risk for hospitalization (OR = 3.15; 95% C.I. 1.38-7.19). CONCLUSIONS: The findings should encourage clinicians to use patient self ratings in order to identify patients with a high risk for hospitalization for targeted interventions.

Cognitive manic symptoms associated with the P2RX7 gene in bipolar disorder.

OBJECTIVE: Several genetic loci have been suggested to be associated with bipolar disorder but results have been inconsistent. Studying associations between bipolar symptoms and candidate genes may better expose this relationship. Here we investigate the association between bipolar key symptoms and the P2RX7 gene. METHODS: Key symptoms of mania were rated in two sets of medicated bipolar disorder patients (n=171 and n=475) at two specialized outpatient clinics for affective disorders and three regular psychiatric outpatient units in Sweden. The relationships between all manic symptoms according to DSM-IV were entered in a principal component analysis. We used a case-case model to reduce the genetic heterogeneity and tested associations between four factors related to manic symptoms and their association to four single nucleotide polymorphisms in the P2RX7 gene. RESULTS: The combination of the cognitive symptoms, distractibility, talkativeness, and thought disorder was significantly associated with rs1718119 in the P2RX7 gene in Set 1 [odds ratio (OR) = 1.78; p=0.011]. The association was re-tested in the second set (OR = 1.42; p=0.009). In the total sample, the association was even stronger (OR = 1.49; p<0.001). None of the other factors was associated with the P2RX7 gene. Within the first factor, the distractibility symptom accounted for a significant portion of the association to rs1718119 (p=0.016). CONCLUSION: There is an association between specific symptoms of bipolar disorder and the P2RX7 gene. This finding may open up new approaches to elucidating the neurobiology behind bipolar symptoms.

Carriers of the UGT1A4 142T>G gene variant are predisposed to reduced olanzapine exposure--an impact similar to male gender or smoking in schizophrenic patients.

PURPOSE: The impact of the UGT1A4, CYP1A2, and MDR1 genetic variants on olanzapine plasma levels, in relation to those of other individual factors, such as gender, smoking status, body weight, and age, was investigated in patients with schizophrenia. METHODS: A total of 121 patients were recruited from psychosis-specialized outpatient departments in Stockholm County. Olanzapine plasma concentrations were determined by high-performance liquid chromatography. Genotyping was carried out by PCR-restriction fragment length polymorphism or minisequencing, and haplotypes were analyzed using specialized computer software on population genetics. Multiple regression analysis was performed to investigate the combined effect of patient characteristics and genotypes/haplotypes on daily dose-corrected plasma concentrations of olanzapine. RESULTS: In addition to , the results indicate that inter-patient differences in olanzapine exposure were explained by the known factor of time of sampling from last dose intake and by the following individual factors in order of relative impact: (1) male gender, (2) carrier of the UGT1A4 142T>G single nucleotide polymorphism (SNP), and (3) smoking. Each of these three factors predicted a decrease in daily dose-corrected plasma concentrations of 35, 25, and 21%, respectively. In contrast, age, body weight, and MDR1 or CYP1A2 haplotype did not have a significant impact. CONCLUSIONS: At 12 h after dose intake, the regression model predicted a 5.1-fold higher olanzapine plasma level in a non-smoking female patient who did not carry the UGT1A4 142T>G SNP compared to a smoking man treated with the same dose but heterozygous for UGT1A4 142T>G SNP. Whether these combined genetic and environmental factors influence the risk of therapeutic failure remains to be established.

Swedish clinical guidelines--prevention and management of metabolic risk in patients with severe psychiatric disorders.

Individuals with severe psychiatric disorders are more likely than the population at large to develop metabolic derangements such as overweight and diabetes. Cardiovascular disease is also more frequently seen in this group. Contributing factors may include inappropriate diet or lack of physical activity, but antipsychotic medication may also play a role. Seven Swedish specialist medical societies have collaborated in formulating a set of concise clinically applicable guidelines-reproduced here in modified form-for the prevention and management of metabolic risk in this patient group. The importance of implementation is emphasized.

Risk factors for suicide in schizophrenia: findings from a Swedish population-based case-control study.

Previous reports regarding risk factors for suicide in schizophrenia have been inconclusive. We performed a matched case-control study of in-patient-treated schizophrenia patients in order to assess the suicide risk associated with socioeconomic, demographic, and psychiatric factors. The cases were 84 patients who died by suicide within five years after diagnosis in a cohort of all patients discharged for the first time from psychiatric hospitals in Stockholm County, Sweden, with a diagnosis of schizophrenia, schizophreniform disorder or schizoaffective disorder between the years 1984 and 2000. One control was individually and randomly matched with each case from the same cohort by date (+/-1 year) and age (+/-5 years) at index diagnosis. Data were retrieved from clinical records of the case-control pairs in a blind fashion. Of the suicides, 54% were men and 46% were women. In multivariate analyses, higher educational attainment (odds ratio [OR] 3.0, 95% confidence interval [CI] 1.03-8.0), age >or=30 years at onset of symptoms (OR 4.8, CI 1.1-21.2), and a history of a suicide attempt requiring non-psychiatric medical treatment (OR 5.0, CI 1.6-15.4) were found to be significantly associated with an increased suicide risk. Gender did not significantly affect the suicide risk, nor did a history of self-discharge, compulsory in-patient treatment, substance-use disorder or a family history of mental disorders or suicide. In schizophrenia, certain suicide risk factors may differ from those in the general population. Clinical suicide risk assessment for schizophrenia patients should be performed taking this into account.

Gender influence on the bipolar disorder inpatient length of stay in Sweden, 2005-2014: A register-based study.

BACKGROUND: The influence of gender on bipolar disorder is controversial and it is unclear if inpatient care differs between men and women. Here, we investigate for gender differences in the inpatient length of stay for Swedes admitted for bipolar disorder and explore other factors that could explain any observed association. METHODS: Admission data were extracted from the Swedish National Patient Register and included all patients first admitted to a psychiatric inpatient unit with a bipolar disorder diagnosis, circa 2005-2014. Patients were then retrospectively followed for subsequent hospitalizations. Diagnostic subtypes were categorized by ICD-10 clusters: depressive, depressive with psychotic features, manic, manic with psychotic features, mixed, and other. Psychotropic therapies preceding the corresponding admissions were attained from the Prescribed Drug Register. Mixed-effects zero-truncated negative binomial regressions were employed to model the length of stay per admission. RESULTS: Analysis included 39,653 admissions by 16,271 inpatients (60.0% women). Overall, when compared to men, women spent 7.5% (95% CI: 4.2-11.0%, p < 0.001) extra days hospitalized per admission. However, upon adjusting for candidate confounders, including the bipolar subtype, and selected comorbidities and psychotropics, the association weakened wherein women then spent 3.7% (95% CI: 0.1-6.9%, p = 0.028) extra days hospitalized per admission. LIMITATIONS: The integrity of register data can be variable and the adherence to outpatient dispensed psychotropics could not be validated. CONCLUSION: Although the influence of gender on the bipolar disorder inpatient length of stay is evident, other factors attenuate and better explain this crude observation.

Suicide Ideation and Behavior as Risk Factors for Subsequent Suicide in Schizophrenia: A Nested Case-Control Study.

OBJECTIVE: To investigate suicide ideation and behavior as risk factors for suicide in schizophrenia during varying time periods. METHOD: Cases were 84 patients who died by suicide within 5 years from diagnosis in a source population of patients discharged for the first time from psychiatric hospitals in Stockholm County, Sweden, with a schizophrenia spectrum diagnosis. One control was individually matched with each suicide case. Data were retrieved from clinical records in a blind fashion. Thoughts of death, thoughts of suicide, suicide plan, and suicide attempt during varying time periods were investigated as risk factors for subsequent completed suicide. RESULTS: In adjusted analyses, thoughts of suicide, suicide plan, and suicide attempt were significantly associated with subsequent completed suicide in the following year. The highest suicide risk was found within a year following suicide attempt (adjusted OR 9.9, 95% confidence interval 2.5-39.0). The association between suicide ideation and behavior and subsequent suicide declined over time. CONCLUSIONS: Several types of suicide ideation and behavior were associated with suicide, and the association was stronger for suicidal behavior. The clinical significance of suicidal communication appears highest during the following month or/and year. Many suicides occurred without recorded short-term suicidal communication.

Outcome of a psychosocial health promotion intervention aimed at improving physical health and reducing alcohol use in patients with schizophrenia and psychotic disorders (MINT).

BACKGROUND: Life expectancy is reduced by 19 years in men and 17 in women with psychosis in Sweden, largely due to cardiovascular disease. AIM: Assess whether a psychosocial health promotion intervention improves cardiometabolic risk factors, quality of life, and severity of illness in patients with psychotic disorders more than treatment as usual. METHODS: A pragmatic intervention trial testing a manual-based multi-component health promotion intervention targeting patients with psychosis. The Swedish intervention was adapted from IMPaCT therapy, a health-promotion program based on motivational interviewing and cognitive behavioral therapy, designed to be incorporated into routine care. The intervention group consisted of 119 patients and the control group of 570 patients from specialized psychosis departments. Outcome variables were assessed 6 months before intervention during the run-in period, again at the start of intervention, and 12 months after the intervention began. The control group received treatment as usual. RESULTS: The intervention had no significant effect on any of the outcome variables. However, BMI, waist circumference, systolic BP, heart rate, HbA1c, general health, and Clinical Global Impressions Scale score improved significantly during the run-in period before the start of the active intervention (observer effect). The multi-component design meant that treatment effects could only be calculated for the intervention as a whole. CONCLUSION: The results of the intervention are similar to those of the U.K. IMPaCT study, in which the modular health-promotion intervention had little effect on cardiovascular risk indicators. However, in the current study, the run-in period had a positive effect on cardiometabolic risk factors.
