Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Suicide behaviors are prevalent among inpatients with schizophrenia. However, the relationships between psychiatric symptoms, sleep disturbances, and suicide risk remain poorly understood in these high-risk populations. WHAT IS ADDED BY THIS REPORT? In a study of 672 schizophrenia inpatients across 9 hospitals in 4 Chinese provinces, the prevalence of suicide risk was 22.3% [95% confidence interval (CI): 19.3%, 25.6%]. The study identified significant associations between suicide risk and multiple clinical factors, including poor sleep quality, depressive symptoms, anxiety symptoms, and other psychiatric manifestations such as thinking disorder and activation. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Understanding the common sleep-related and psychiatric factors associated with suicide risk in hospitalized schizophrenia patients will enable clinicians and policymakers to better identify clinical risk indicators and enhance the quality of suicide prevention and treatment programs.
