Abstract

OBJECTIVES: We investigated suicide timing over different time periods by age, sex and race/ethnicity.

METHODS: 122,107 suicide deaths were identified from the population-based U.S. National Violent Death Reporting System in 18 U.S. States from 2003 through 2014.

RESULTS: Suicides significantly increased (p < 0.05) from March to peak in September before falling, the first week of the month, and early in the week. Suicides also significantly increased (p < 0.05) in the morning, mainly peaking during the afternoon, although suicides in adolescents peaked in the evening and in those 65 years and older peaked in the morning.

CONCLUSIONS: Comprehensive prevention efforts should focus on those at overall increased suicide risk and at peaks of high suicide frequency, especially among those vulnerable subgroups.
