Resumen
Objective: Bipolar disorder (BD) is a highly prevalent, chronic and recurrent
mental illness. The smoking rates in patients with BD are much higher than those
of the general population, and BD is associated with an increased risk of suicide.
An association between smoking and suicidal behavior has been found in the
general population, this systematic review examines whether there is evidence of
an association between smoking and suicide behavior in patients with BD.
Method: A database search was carried out in Medline, Embase, The Cochrane
Library, Scopus, and Web of Science, updated until December 31st, 2021, according
to the 2020 PRISMA guidelines. We identified prospective and retrospective studies
that included patients diagnosed with BD types I, II, and not otherwise specified,
and in which smoking and suicidal behavior were correlated. Articles that focused
exclusively on other mental disorders were excluded. The Ottawa-Newcastle scale
was used to assess the methodological quality of the included articles.
Results: Fifteen articles (n = 7,395) met all the inclusion criteria. In nine of these
articles, the authors found an association between smoking and suicidal behavior in
BD, while in the remaining six articles, this association was not found. A great deal of
variability was observed between articles, particularly in the measurement of suicidal
behavior and tobacco consumption. The risk of bias, as assessed by the NOS, was
high for most of the included articles, except for two papers, whose risk was low.
Conclusion: It was not possible to establish a clear relationship between tobacco
use and the risk of suicide in BD patients due to the heterogeneity of the
articles included in this systematic review, which had different sample sizes and
methodological issues. However, both conditions are highly prevalent and have
a negative impact on the prognosis of BD. Therefore, a systematic approach is
needed, based on accurate measurement of a patient’s smoking habits and their
risk of suicidal behavior, in order to establish an appropriate therapeutic plan.
