Risk factors for violent suicide attempts: Hungarian cross-sectional study.

backgroundIndividuals who die by suicide tend to share more characteristics with those who attempt suicide using violent methods than with those who employ nonviolent means. To date, limited research has been published on the demographic characteristics of individuals who engage in violent suicide attempts.

objectivesThis study aimed to examine trends in the characteristics of violent suicidal behavior in comparison to nonviolent suicidal behavior.

methodsPatients included in the study were consecutively admitted between 2016 and 2021 to the Dr. Manninger Jenő National Trauma Center and the Psychiatric and Toxicology Wards of Péterfy Sándor Hospital in Budapest, Hungary, for medical treatment following violent or nonviolent suicide attempts. Differences in demographic characteristics, risk factors associated with violent suicidal behavior, and methods of attempt were analyzed using Chi-square tests and logistic regression models.

resultsA total of 298 inpatients (46.1% male, 53.9% female), aged between 18 and 65 - representing the economically active population - were included in the study. The sample comprised 145 individuals who attempted suicide using nonviolent methods (73% female, 27% male) and 153 who used violent methods (64.7% male, 35.3% female). Of the total sample, 22 individuals (12.1%) died during treatment due to severe medical complications. Among male attempters, the highest proportion fell within the economically active age range of 18-55 years, whereas among female attempters, the 18-35 age group represented the highest proportion. The most common violent methods, in descending order of frequency, were stabbing (49.7%), jumping from a height (29.8%), and jumping in front of a train (7.7%). The most frequently diagnosed psychiatric disorders among the sample were major depressive disorder (42.2%), anxiety disorders (44.9%), and bipolar disorder (12%). The leading reported motives for violent suicide attempts, in decreasing order of frequency, were marital conflict (32.4%), divorce/separation/break-up (30.2%), and severe or chronic somatic illnesses (12%). When comparing the two subgroups, the strongest risk factors associated with violent suicide methods included male gender, older age, and residence in the capital city.

conclusionsPrevious studies suggest that risk factors are largely indistinguishable between individuals who engage in violent versus nonviolent suicide attempts. However, individuals who attempted suicide using violent methods exhibited characteristics more closely aligned with those who died by suicide than with the remainder of the sample. The majority of data in this study were collected during the COVID-19 pandemic - a period marked by multiple overlapping crises - which may have played a disproportionately large role in the emergence of suicide risk.
