Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact firstname.lastname@example.org.
Suicide and Quarantine During the COVID-19 Pandemic: Do We Know Everything?
23 Pages Posted: 14 Oct 2021More...
Background: There is widespread concern over the impact of COVID-19 and lockdown measures on suicidal behaviour. We assessed their effects on suicide and hospitalization for attempted suicide in Chile.
Methods: We used panel data at the county and month level from January 1, 2016 to December 31, 2020 on suicides and related hospitalizations and a pandemic quarantine dataset. Poisson regression models and a difference-in-difference (DiD) methodology was used to estimate the impact of quarantine on both measures.
Findings: Suicide and hospitalizations for attempted suicide decreased (18% and 5·8%, respectively) during the COVID-19 outbreak in Chile (March-December 2020) compared to the same period in 2016-2019. The DiD analysis showed that there was at least a 13·2% reduction in suicides in quarantined counties relative to counties without such restrictions. This reduction was in male suicides and unaffected by age. There was no significant difference between quarantined and non-quarantined counties in terms of hospitalization for suicide attempts.
Interpretation: This study shows a significant quarantine effect on reducing suicide during the COVID-19 pandemic. Changes in the number of hospitalizations for suicide attempts do not explain the differences between quarantined and non-quarantined counties.
