Abstract

Metabolic syndrome (MetS) and its components are highly predictive of cardiovascular diseases. The primary aim of this systematic review and meta‐analysis was to assess the prevalence of MetS and its components in people with schizophrenia and related psychotic disorders, bipolar disorder and major depressive disorder, comparing subjects with different disorders and taking into account demographic variables and psychotropic medication use. The secondary aim was to compare the MetS prevalence in persons with any of the selected disorders versus matched general population controls. The pooled MetS prevalence in people with severe mental illness was 32.6% (95% CI: 30.8%‐34.4%; N = 198; n = 52,678). Relative risk meta‐analyses established that there was no significant difference in MetS prevalence in studies directly comparing schizophrenia versus bipolar disorder, and in those directly comparing bipolar disorder versus major depressive disorder. Only two studies directly compared people with schizophrenia and major depressive disorder, precluding meta‐analytic calculations. Older age and a higher body mass index were significant moderators in the final demographic regression model (z = −3.6, p = 0.0003, r 2 = 0.19). People treated with all individual antipsychotic medications had a significantly (p<0.001) higher MetS risk compared to antipsychotic‐naïve participants. MetS risk was significantly higher with clozapine and olanzapine (except vs. clozapine) than other antipsychotics, and significantly lower with aripiprazole than other antipsychotics (except vs. amisulpride). Compared with matched general population controls, people with severe mental illness had a significantly increased risk for MetS (RR = 1.58; 95% CI: 1.35‐1.86; p<0.001) and all its components, except for hypertension (p = 0.07). These data suggest that the risk for MetS is similarly elevated in the diagnostic subgroups of severe mental illness. Routine screening and multidisciplinary management of medical and behavioral conditions is needed in these patients. Risks of individual antipsychotics should be considered when making treatment choices.

TL;DR

This systematic review and meta-analysis found that metabolic syndrome (MetS) affects about one third of people with severe mental illness and is elevated versus matched general population controls. Risk was similar across schizophrenia, bipolar disorder, and major depressive disorder, but differed by age, body mass index, and individual antipsychotic medication.

Key findings

  • Pooled MetS prevalence in people with severe mental illness was 32.6% (95% CI: 30.8%–34.4%; N=198; n=52,678), and compared with matched general population controls the relative risk was 1.58 (95% CI: 1.35–1.86; p<0.001).
  • MetS prevalence did not differ significantly in direct comparisons of schizophrenia versus bipolar disorder (RR=0.92, 95% CI: 0.79–1.06; p=0.24) or bipolar disorder versus major depressive disorder (RR=0.87, 95% CI: 0.48–1.55; p=0.64); only two studies directly compared schizophrenia and major depressive disorder, precluding meta-analysis.
  • Older age and higher body mass index were significant moderators in the final demographic regression model (z=23.6, p=0.0003, r²=0.19).
  • Among antipsychotics, MetS prevalence was lowest for aripiprazole (19.4%, 95% CI: 8.0%–34.2%) and highest for clozapine (47.2%, 95% CI: 42.0%–52.6%); antipsychotic-naïve participants had 10.2% (95% CI: 6.8%–14.3%). Compared with controls, risk was increased for all MetS components except hypertension, which showed a statistical trend (RR=1.12, 95% CI: 0.99–1.28; p=0.07).

Methods

  • Systematic review and meta-analysis conducted according to MOOSE and PRISMA, searching MEDLINE, PsycARTICLES, EMBASE, and CINAHL from database inception to January 1, 2015.
  • Included observational studies in adults with DSM-IV/ICD-10 diagnoses of schizophrenia or related psychotic disorders, bipolar disorder, or major depressive disorder, and MetS defined by non-modified ATP-III, ATP-III-A, IDF, or WHO criteria; 198 studies with 52,678 unique persons with severe mental illness were included.
  • Pooled prevalence used the DerSimonian-Laird random-effects proportion method; relative risks were calculated for MetS and its components within and across diagnostic subgroups and versus matched general population controls, with meta-regression for moderators.

Limitations

  • The paper states considerable methodological heterogeneity across studies; cross-sectional data meant directionality of medication–metabolic associations could not be deduced with certainty; clinical subtypes and concomitant or previous antidepressant/mood stabilizer use were often insufficiently reported or controlled; publication bias and heterogeneity were encountered, though main findings were robust after trim-and-fill adjustment; and inadequate data on ethnicity and lifestyle behaviors precluded meta-analytic assessment of these factors.
  • Evident from the text: there were no data in first-episode bipolar disorder or major depressive disorder patients, precluding comparison with multi-episode patients, and only two studies directly compared schizophrenia and major depressive disorder.
  • Evident from the text: illness duration was a significant predictor in separate meta-regression but not in the final model, which the authors note may be due to limited data available for illness duration compared with age.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.
