This study aimed to understand the prevalence of suicide and non-suicidal self-injury (NSSI) in South Bangka Regency using a quantitative approach with a descriptive study design. Data was collected from electronic medical records at Junjung Besaoh Regional Hospital between September 2023 and July 2025. The results showed that the male-to-female suicide ratio was 1.14:1, with male suicides being more lethal. Suicides and NSSI were most common in adults (83.33%; 86.67%), with both unmarried and married individuals equally represented in suicide cases (50.00%), while NSSI was more common in those without marital status (60.00%). Unemployed individuals (36.66%) were the most common group for suicide, while contract employees (40.00%) had higher rates of NSSI. Sharp objects and self-poisoning were the most common methods for suicide (43.33% each), while NSSI often involved barcodes (53.33%). Among suicide cases, 56.67% had a known psychiatric diagnosis, while 66.67% of NSSI cases had one. Relationship issues were the most common reason for both suicide (56.67%) and NSSI (66.67%). This study found an annual increase in cases and identified male gender, adulthood, and unemployment as risk factors for suicide. The findings aim to inform local governments and hospitals in planning suicide prevention and treatment programs.
