Mortality Disparities Among Arrestees by Race, Sentencing Disposition, and Place

Abstract

ImportanceUnderstanding mortality disparities among justice system–involved populations is crucial for public health and policy, especially for marginalized racial groups such as American Indian/Alaska Native persons.ObjectiveTo examine racial disparities in mortality within the broader justice system–involved population in South Dakota, focusing on different sentencing dispositions and the role of place.Design, Setting, and ParticipantsThis observational study used administrative criminal records linked to mortality data from January 2000 to December 2016. The statewide data linked data from South Dakota Attorney General’s Office and South Dakota Department of Health. Individuals aged 18 years and older with arrests were analyzed in this population-based sample. Data were analyzed from August 1, 2022, to July 30, 2023.ExposureSentencing dispositions were categorized as arrest only, fine, probation, jail, and prison.Main Outcomes and MeasuresThe main outcomes were mortality rates (both all-cause and cause-specific) calculated using Poisson regression models, adjusted for demographic and county variables.ResultsOf 182 472 individuals with 422 987 arrests, the study sample included 29 690 American Indian/Alaska Native arrestees (17 900 [60%] male; mean [SD] age, 29.4 [11.0] years) and 142 248 White arrestees (103 471 [73%] male; mean [SD] age, 32.6 [12.9] years). American Indian/Alaska Native persons accounted for 16% of arrestees and 26% of arrests, but only 9% of the population in South Dakota. Across dispositions, mortality risk was greater for White individuals sentenced to probation, jail, and prison relative to White individuals who were arrested only. In terms of racial disparities, all-cause mortality risk was 2.37 (95% CI, 1.95-2.88) times higher for American Indian/Alaska Native than White arrestees in the arrest-only disposition. Disparities persisted across all dispositions but narrowed substantially for probation and prison. Results were similar for cause-specific mortality risk, except for cancer risk. In urban areas, mortality risk was 2.70 (95% CI, 1.29-2.44) times greater for American Indian/Alaska Native individuals relative to White individuals among those with arrest-only dispositions.Conclusions and RelevanceIn this population-based observational study, mortality risk and associated racial disparities among justice system–involved individuals differed substantially across dispositions and places, underscoring the need for public health interventions tailored to these factors. Further research is needed to understand the mechanisms through which sentencing and place shape these disparities.
