Key Points
Question Are increases in suicide rates associated with more suicidal acts, suicidal acts becoming more lethal, or a combination of both?
Findings In this cross-sectional study based on national representative data of 1 222 419 suicidal acts, increased suicide rates were associated with an increase in both incidence rates and lethality of suicidal acts from 2006 to 2015. In subgroup analyses, incidence of suicidal acts increased among female persons, adolescents, and older adults aged 65 to 74 years, whereas suicidal acts became more lethal among both sexes and persons aged 20 to 64 years.
Meaning These findings on population-level epidemiologic patterns may advance the understanding of suicide trends to guide prevention efforts.
