Suicide is a global issue, with approximately 800,000 suicides reported worldwide in 2015, accounting for 1.4% of premature deaths. Suicide rates vary by age, gender, and socioeconomic status, with males completing suicide more frequently than females. Suicide attempts are more common than completed suicides, but they are significant predictors of repeated attempts and completed suicides. The most common methods include hanging, pesticide poisoning, and firearm use. Mental disorders, particularly depression, substance use, and psychosis, are major risk factors for suicide. Suicide rates are higher in low- and middle-income countries (LMIC), where underreporting is likely. Prevention strategies include restricting access to suicide means, training healthcare professionals to identify at-risk individuals, and improving media reporting. Suicide is a significant public health issue requiring global attention. Suicide rates vary by region, with Europe having the highest rates. Suicide rates among young people are higher than in older adults, and gender differences are evident. Socioeconomic factors, such as poverty and inequality, contribute to higher suicide rates. Special groups, including the elderly, military personnel, and individuals with mental illnesses, are at higher risk. Suicide prevention measures, including primary and secondary prevention, are essential. Data quality is a challenge, with underreporting and misclassification of suicide cases. Suicide prevention is possible through targeted interventions and improved healthcare systems.Suicide is a global issue, with approximately 800,000 suicides reported worldwide in 2015, accounting for 1.4% of premature deaths.
