Abstract

Suicidality in autistic youth is a major public health issue. This study aimed to determine global prevalence of, and risk/protective factors for suicidality in autistic youth via systematic review and meta-analysis. We systematically searched Embase, PubMed, PsycINFO, Web of Science, and the Cochrane library for studies from inception to November 22nd, 2021. We selected empirical studies reporting on suicide outcomes (i.e., ideation, behaviors, attempts and deaths) in autistic youth (≤25 years). Random effects models were used to estimate the pooled prevalence of suicide outcomes with 95% confidence interval (CI). Heterogeneity was investigated with potential moderators using meta-regression analyses. The final selection included 47 papers, 29 of which were included in meta-analyses and 37 were narratively synthesized (sociodemographic, psychiatric, psychological, other factors, and interventions). The pooled prevalence of suicidal ideation was 25.2% (95% CI 18.2-33.8; i.e., one in four), suicide attempts 8.3% (3.6-18.2), and suicide deaths 0.2% (0.05-0.52). Estimates in self-reports were higher than in parent-reports. Age was a significant but inconsistent moderator on suicide outcomes, but substantial heterogeneity remained. Adverse childhood experiences were strong risk factors for suicidality, while resilience was protective. Participatory suicide risk-assessment, early intervention, and resilience promotion should be primary clinical/research goals.

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.

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.
