Adolescent Police Stops, Self-Harm, and Attempted Suicide: Findings From the UK Millennium Cohort Study, 2012‒2019
Abstract
Objectives. To explore associations between police stops, self-harm, and attempted suicide among a large, representative sample of adolescents in the United Kingdom. Methods. Data were drawn from the 3 most recent sweeps of the UK Millennium Cohort Study (MCS), from 2012 to 2019. The MCS is an ongoing nationally representative contemporary birth cohort of children born in the United Kingdom between September 2000 and January 2002 (n = 10 345). Weights were used to account for sample design and multiple imputation for missing data. Results. Youths experiencing police stops by the age of 14 years (14.77%) reported significantly higher rates of self-harm (incidence rate ratio = 1.52; 95% confidence interval [CI] = 1.35, 1.69) at age 17 years and significantly higher odds of attempted suicide (odds ratio = 2.25; 95% CI = 1.84, 2.76) by age 17 years. These patterns were largely consistent across examined features of police stops and generally did not vary by sociodemographic factors. In addition, 17.73% to 40.18% of associations between police stops and outcomes were explained by mental distress. Conclusions. Police-initiated encounters are associated with youth self-harm and attempted suicide. Youths may benefit when school counselors or social workers provide mental health screenings and offer counseling care following these events. (Am J Public Health.

How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 10 participants or records.
