Special Issue Information

Dear Colleagues,

Suicide carries a significant global burden. Despite being preventable, research on suicide and its prevention has received inadequate financial and human investment. This Special Issue provides a comprehensive overview of suicide, attempt assessments, and prevention efforts around the world, identifying evidence-based approaches for developing policies and programs which can be adapted to different settings. This Special Issue is expected to serve as a foundation for the development and implementation of comprehensive suicide prevention strategies around the world. Suicide prevention begins with surveillance in order to define and understand the problem, followed by the identification of risk, protective factors, and effective interventions, and, finally, implementation, which includes intervention evaluation and improvement, a review of the surveillance, and moving to the next step. There must also be vision, political will, leadership, stakeholder buy-in, and, crucially, funding to help support suicide prevention, along with data to guide its development, implementation, and evaluation. The incidence, characteristics, and methods of suicidal behavior vary across regions, demographic groups, and time. Thus, there is a need to understand the ways to improve the monitoring of suicidal behavior, identify the causes of large variations in suicide rates across regions and countries, and determine the modifiable factors influencing suicide rates through policies and programs.

Considering the above, this Special Issue welcomes papers related to the following:

  • Assessment and management of suicidal behavior, mental health issues, and substance use disorders;
  • Follow-up and community support for discharged patients;
  • Improved access to health care (improved mental health literacy);
  • Increased awareness of mental health and suicide (e.g., reduced stigma);
  • Intervention and postvention support for vulnerable groups;
  • Interventions related to community and relationship risk factors;
  • Interventions related to health system and societal or individual risk factors;
  • Management of gatekeeper training and crisis support services;
  • Measures for responsible media reporting;
  • Mental health policies intended to reduce suicide mortality;
  • Restricted access to tools (e.g., pesticides, firearms, and hazardous gasses).

Suicide is a major public health problem that has grown at alarming rates in the last two decades. Colorectal cancer (CRC) is one of the most common causes of cancer deaths in the United States in both males and females. However, the influence of suicidal ideation (SI) on the association between CRC and risk of mortality has not been well examined. Methods: For this study, the 2005–2018 National Health and Nutrition Examination Survey (NHANES), a nationally representative survey of United States adults aged 20 years or older, was utilized. CRC survivorship was determined from self-reported data on CRC, and mortality was ascertained by linking the NHANES data with death files from the National Death Index up to December 2019. Suicidal ideation (SI) confirmation was based on a response to a survey question. Results: People with SI had a significantly higher rate (12.3% vs. 7.5%, p < 0.01) of mortality than those without SI. Also, individuals with CRC (2.4%) had a statistically significant higher rate of frequent SI (almost daily) than individuals without CRC (0.6%). Upon a mean follow-up of 7.5 years, more CRC survivors (34.6%) died than non-CRC survivors (7.6%). The adjusted HR was elevated HR = 5.4 among individuals who had CRC and SI but close to 1.0 among individuals who had a history of CRC alone after adjusting for demographic and health variables. Conclusions: In this first national study in the U.S., we found that SI and CRC combined had worse mortality outcomes than CRC alone. Additionally, people with CRC were more likely to experience frequent SI. Our findings underscore the importance of mental healthcare and psychological well-being promotion among individuals with chronic diseases and the high need for integrated care approaches that address both physical and mental health needs.
