INTRODUCTION: Recent decades have seen an uptick in suicide attempts and completed suicides among adolescents and young adults worldwide. In the Americas, including Cuba, suicide is the third leading cause of death in adolescents (ages 10-19 years).
OBJECTIVE: Characterize the epidemiology of attempted and completed suicide in Cuban adolescents from 2011 through 2014.
METHODS: A descriptive epidemiological study was carried out. The information was gathered from morbidity records for suicide attempts and mortality records for suicide deaths in adolescents, taken from the Cuban Ministry of Public Health's Medical Records and Health Statistics Division database for January 1, 2011 through December 31, 2014. Variables were sex, age, occupation or employment status, and suicide method. Suicide attempt incidence rates and suicide mortality rates by age group per 100,000 population (crude, adjusted and age/sex specific), mortality sex ratio and attempt/suicide ratio were calculated. Relative change was calculated as a percentage, as were frequencies by variable for attempted suicide and suicide, and by age and sex for method used.
RESULTS: A total of 19,541 suicide attempts and 149 suicides were reported. Average annual numbers were 4,885.2 suicide attempts and 37.2 suicides (131:1 ratio). There were 3,966 suicide attempts among boys, for a sex ratio of 0.25:1. Age-adjusted suicide attempt rates decreased from 391.8 per 100,000 population to 304.5 (22.3% reduction over the study period). Boys accounted for 107 of 149 suicide deaths, for a sex ratio of 2.5:1. Age-adjusted suicide mortality rates decreased from 2.8 to 2.3 per 100,000 population (17.9% reduction). The group aged 15-19 years had the highest age-adjusted suicide rate (3.9 per 100,000 population) and contributed the most deaths (114/149, 76.5%), although it did experience a 31.8% reduction over the study period. The group aged 10-14 years recorded a relative increase of 60% over the study period. Hanging was the most common suicide method (116/149, 77.9%). The suicide rate in Cuban adolescents (2.6 per 100,000 population, 3.7 in boys and 1.5 in girls) is less than that reported by the Region of the Americas between 2005 and 2009, 3.7 per 100,000 population (5/100,000 in boys and 2.3/100,000 in girls).
CONCLUSIONS: Suicide rates in Cuban adolescents are lower than reported elsewhere in the Americas. Suicide attempts and suicide rates decreased modestly between 2011 and 2014. Hanging is the most commonly used method. The highest rates occur in the group aged 15-19 years, but those aged 10-14 years showed a relative increase over the study period. These results update the epidemiology of suicide in Cuban adolescents and demonstrate the extent of the problem. Suicides and suicide attempts show opposite patterns in boys and girls; suicides are more frequent among boys while suicide attempts are more frequent among girls. CONTRIBUTION OF THIS RESEARCH: These results update the epidemiology of suicide in Cuban adolescents and reveal the extent of the problem for one of the main preventable causes of death in this age group.
