Prevalence and correlates of childhood-onset bipolar disorder among adolescents

Abstract

AIM: Early-onset bipolar disorder (BD) is associated with a more severe illness as well as a number of clinical factors among adults. Early-onset can be categorized as childhood- (age < 13) or adolescent- (age ≥ 13) onset, with the two displaying different clinical profiles. We set out to examine differences in clinical, and familial characteristics among adolescents with childhood- versus adolescent-onset BD. METHODS: The study included 195 adolescents with BD, ages 14-18 years. Age of onset was determined retrospectively by self-report. Participants completed the semi-structured K-SADS-PL diagnostic interviews along with self-reported dimensional scales. Analyses examined between-group differences for clinical and familial variables. Variables associated with age of onset at p < 0.1 in univariate analyses were evaluated in a logistic regression model. RESULTS: Approximately one-fifth of participants had childhood-onset BD (n = 35; 17.9%). A number of clinical and familial factors were significantly associated with childhood-onset BD. However, there were no significant differences in depressive and manic symptom severity. In multivariate analyses, the variables most strongly associated with childhood-onset were police contact, and family history of suicidal ideation. Smoking and psychiatric hospitalization were associated with adolescent-onset. CONCLUSIONS: In this large clinical sample of adolescents with BD, one-fifth reported childhood-onset BD. Correlates of childhood-onset generally aligned with those observed in the literature. Future research is warranted to better understand the genetic and environmental implications of high familial loading of psychopathology associated with childhood-onset, and to integrate age-related treatment and prevention strategies.

  • Smoking is a risk factor for an earlier age of onset of bipolar disorder.

    “Smoking as a risk factor for an earlier age of onset of BD was also found in an Italian study in more than 1,000 patients of specialized outpatient clinics (41) and in a clinical sample of 195 adolescents from the US with BD (42).”

    From The detrimental effects of smoking on the course and outcome in adults with bipolar disorder—A narrative review (2023) · cites this paper as [42]

    The Discussion (pp. 8–9) reports the opposite association in the study’s 195 adolescents with bipolar disorder: childhood-onset was negatively associated with lifetime smoking. The Multivariate analyses (p. 7) also report a significant negative association. The paper does not establish smoking as a risk factor for earlier onset. (LLM, conf=0.90)

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.
