The U.S. Criminal Legal System and Population Health.

Area of Science:

• Public Health
• Social Epidemiology
• Health Disparities Research

Background:

• The criminal legal system is increasingly recognized as a critical social determinant of health.
• Prior research focused on incarceration, but recent studies include community supervision and police contact.
• Existing evidence highlights elevated physical and mental health risks associated with criminal legal system involvement.

Purpose of the Study:

• To describe the U.S. criminal legal landscape.
• To summarize recent research on the criminal legal system's impact on population health.
• To identify future research directions for understanding this relationship.

Main Methods:

• Review of existing literature on the criminal legal system and health.
• Synthesis of findings on direct and indirect contact with the system.
• Identification of limitations in current research methodologies.

Main Results:

• Contact with the criminal legal system, including incarceration, supervision, and police encounters, is linked to adverse health outcomes.
• Research has expanded beyond incarceration to include other forms of legal system contact.
• Significant gaps remain in understanding the longitudinal effects and causal mechanisms.

Conclusions:

• The criminal legal system is a major driver of population health and health disparities.
• More research is required to elucidate the pathways through which legal system contact affects health.
• Future studies should employ causal modeling and measure underlying mechanisms more effectively.
