INTRODUCTION: Suicidal behavior is a public health problem worldwide. The World Health Organization estimated 700 000 deaths for the year 2021.
OBJECTIVE: This study aimed to estimate the prevalence of suicidal behavior and describe its related factors in the Coquimbo Region, Chile, between 2018 and 2020.
METHODS: 2190 suicide attempt notifications from the regional epidemiological surveillance system were analyzed, corresponding to 1781 people, along with 217 reports from the Forensic Medical Service of people who died by suicide.
RESULTS: The overall suicide rate for the region during that period was 9.79 deaths per 100 000 inhabitants. The 2018 rates were standardized according to available information, with direct methods for the regional rate (9.55 per 100 000 inhabitants) and indirect methods for the communes. Rural communes presented higher rates than urban ones. Women showed a higher risk of attempts (OR 1.28; 95% CI 1.23 to 1.33) and a lower risk of suicide compared to men (0.086; 0.06 to 0.13). Young people had a higher risk of suicide attempts and a lower risk of suicide compared to older people. The increased suicide rates in older people (70 to 79 years) during 2020 are noteworthy. Basic education level is a risk variable for suicide (2.21; from 1.15 to 4.23), compared to having higher education. Previous suicide attempts and psychiatric pathology are risk factors.
CONCLUSIONS: Suicide prevalence and related factors are similar to those reported in other studies and national reports, highlighting rurality and higher risk in older male adults. In contrast to suicides, attempts are more frequent in women and young people. A history of mental health problems, previous attempts, and family violence are risk factors for both outcomes. Knowing the patterns of suicidal behavior in the population is fundamental for its prevention.
