Suicidal behaviors among adults

Résumé

Suicidal behaviors are fatal or nonfatal outcomes of complex, dynamic trajectories of risk and protection. This chapter describes the epidemiology of fatal and nonfatal suicide events among adults in the United States. It discusses sources of data on suicide mortality and morbidity, and methodological challenges associated with obtaining reliable and valid information. Recent data on incidence of suicide fatalities among US adults, prevalence and incidence of nonfatal suicidal behaviors, mechanism of injury, sociodemographic characteristics, onset, and course are presented. Key distal and proximal risk processes for suicide mortality and morbidity in adults are discussed from an individual and environmental perspective. The chapter concludes with a brief overview of how an understanding of the complex trajectories that contribute to suicidal behaviors may be leveraged to identify potential opportunities for preventive intervention and promising directions for future research.
